Description:
A VITRIFIED CASTING MACHINE WITH IMPROVED OPERATING CHARACTERISTICS

FIELD OF THE INVENTION

The invention relates to at least one casting machine with at least one lower table and at least one upper table, which are mutually provided on at least one body and in which at least one mold can be positioned to manufacture vitrified products.

PRIOR ART

Today, vitrified products such as sinks, shower trays, and toilets are manufactured in casting machines. In these casting machines, vitrified products are obtained by pouring the raw material into the mold formed in a predetermined way and drying it. Thanks to the casting machines, production standardization is ensured by the manufacturing of products with predetermined dimensions and aesthetics.

The casting process is performed by moving the molds towards each other in the casting machines. There are hydraulic systems in the casting machines for moving the molds. These hydraulic systems are used to move the mold parts. These hydraulic systems, which are used in the current art, are very expensive since they have a complex structure. The use of such systems in casting machines also increases the cost of the machine. In this case, it also increases the production costs of the vitrified products produced as a result of molding. In addition, high-pressure oils are used for mobility in hydraulic systems known in the current art. These high-pressure hydraulic systems are also likely to malfunction. In this case, there may be frequent stops during production and it may take a long time to repair. In addition, it is necessary to use oil in hydraulic systems known in the art and to change the oil periodically. This creates extra costs for the production of vitrified products.

All the problems mentioned above have made it necessary to make an innovation in the related technical field as a result.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to the casting machine to eliminate the above-mentioned disadvantages and bring new advantages to the related technical field. An object of the invention is to provide the casting machine with an improved movement mechanism for moving the upper table relative to the lower table.

The present invention is at least one casting machine with at least one lower table and at least one upper table, which are mutually provided on at least one body and in which at least one mold can be positioned to manufacture vitrified products to realize all the objects that are mentioned above and will emerge from the following detailed description. Accordingly, its novelty is that it comprises at least one movement nut to which the said upper table is associated to move the upper table relative to the said lower table in at least one vertical axis, at least one worm gear shaft that allows the said movement nut to be moved in the said vertical axis by rotating it around itself, at least one movement mechanism with at least one drive element to rotate the said worm gear shaft around itself. Thus, the movement mechanism used in the movement of the lower table and the upper table relative to each other in the casting machines is simplified to increase the service life and reduce the possibility of failure thereof.

A possible embodiment of the invention is characterized in that it comprises at least one reducer between the worm gear shaft and the drive element on the said movement mechanism. Thus, speed adjustment of the movement mechanism can be made.

Another possible embodiment of the invention is characterized in that it comprises at least one locking assembly for fixing the position of the upper table in the vertical axis. Thus, the upper table can be fixed by leaning on the lower table.

Another possible embodiment of the invention is characterized in that it comprises at least one piston on at least one among the body and the upper table and at least one hole that can be aligned with the said piston on the other in the said locking assembly. Thus, fixation can be made by passing the piston into the hole.

Another possible embodiment of the invention is characterized in that there are mutually positioned struts on the body, each of the said struts comprising a movement mechanism. Thus, the upper table and the lower table can be moved in a balanced manner relative to each other. Another possible embodiment of the invention is characterized in that the vitrified product manufactured is a sink. Thus, sink production can be made in the casting machine at a low cost.

DETAILED DESCRIPTION OF THE INVENTION

The subject of the invention is explained with examples that do not have any limiting effect only for a better understanding of the subject in this detailed description.

A representative perspective view of the casting machine (1) of the invention is given in Figure 1. Accordingly, the casting machine (1) ensures that especially vitrified products are manufactured from sludge/liquid mortar. The said vitrified products in the invention are domestic products manufactured with clay and kaolinite mixed with clay. The vitrified product is preferably a sink.

The casting machine (1 ) has at least one body (10). The said body (10) has struts (11) that are essentially positioned opposite each other. The said struts (11 ) are positioned substantially parallel to each other and are held to each other by at least one mount (12) from their upper parts. There is at least one mold (20) between the struts (11 ) in the body (10). This mold (20) ensures that the specially prepared mortar is injected into the vitrified product and shaped while it is being manufactured. For this, the mold (20) has an essentially two-part structure. These may be characterized as lower mold (21 ) and upper mold (22). This lower mold (21) and the upper mold (22) are leaned against each other to create a closed volume between them and the mortar is filled in this part. When the mortar takes the form of the mold (20), the lower mold (21 ) and the upper mold (22) move away from each other and the obtained vitrified product is removed. The mold (20) must be at least two-piece for removal of the vitrified product. Molding is done by leaning at least one of the parts of this mold (20) relative to the other, and the molded vitrification product is removed by separating the molds (20) from each other.

A representative frontal view of the casting machine (1 ) of the invention is given in Figure 2. Accordingly, the mold (20) is associated with at least one lower table (14) and at least one upper table (13). In the invention, the lower mold (21 ) is connected with the lower table (14) and the upper mold (22) is connected with the upper table (13). Preferably, the lower table (14) is fixedly connected to the body (10). The said upper table (13) is configured to be at least partially moved on the vertical axis (I) on the body (10). The movement of the upper table (13) on the body (10) is provided by at least one movement mechanism (30).

A representative frontal view of the movement mechanism (30) in the casting machine (1) of the invention is given in Figure 3. Accordingly, the movement mechanism (30) is configured to move the upper table (13) at least partially in the vertical axis (I). For this, the movement mechanism (30) comprises at least one drive element (31 ). The drive element (31) provides the motion energy required by the movement mechanism (30). There may be various gearboxes on the drive element (31 ) that may allow speed adjustment in a possible embodiment of the invention. In addition, the drive element (31) may be an electric motor or a hydraulic drive source in possible embodiments of the invention. The drive element (31) is essentially positioned on the mount (12). The drive element (31 ) is configured to transfer power to at least one reducer (32). For this, there is at least one transmission arm (33) for transferring the movement between the said reducer (32) and the drive element (31). The reducer (32) is a gear system that changes the speed-torque ratio of the rotational movement with the help of the gears in it. The reducer (32) is connected with at least one worm gear shaft (34). The reducer (32) transfers the movement it receives from the drive element (31) to the worm gear shaft (34) by regulating it in a speed/torque ratio at predetermined rates. With this motion transfer, the worm gear shaft (34) can rotate around itself. There is at least one movement nut (35) on the worm gear shaft (34). This movement nut (35) moves in the vertical axis (I) by rotating the worm gear shaft (34) around itself. The movement nut (35) is connected with the upper table (13). The upper table (13) also moves as the movement nut (35) moves on the vertical axis (I). With the movement of the upper table (13), the upper mold (22) can be separated from the lower mold (21). In this way, molding and removal from the mold (20) can be easily done. Axising can be performed to improve the rotation of the worm gear shaft (34) around itself in the vertical axis (I). For this, the worm gear shaft (34) is connected with at least one bearing (36) on one side. The said bearing (36) contributes to the improvement of the rotation properties by preventing the worm gear shaft (34) from oscillating while rotating around itself.

In the movement mechanism (30), the reducer (32), the worm gear shaft (34), and the movement nut (35) to which the drive element (31 ) is connected are preferably provided per the number of each strut (11 ). There are two struts (11) positioned opposite each other in the casting machine (1) according to the invention. Thanks to the worm gear shaft (34) and the movement nut (35) on these struts (11), the upper table (13) can be moved in a balanced way in the vertical axis (I).

There is at least one wheel assembly (40) on the upper table (13). This wheel assembly (40) is associated with at least one slide (41 ) provided on the struts (11 ). The wheel assembly (40) on the wheel assembly (40) makes a sliding movement on the slide (41). The structure of the wheel assembly (40) and the slide (41 ) is provided on multiple sides between the upper table (13) and the struts (11). In fact, with the movement of the wheel assembly (40) on the slides (41 ) in the vertical axis (I), the centering is done. In this way, the stability of the movement of the upper table (13) in the vertical axis (I) is ensured.

There is also at least one locking assembly (50) between the upper table (13) and the body (10). The said locking assembly (50) allows the position of the upper table (13) in the vertical axis (I) to be fixed independently of the movement mechanism (30). For this, there is at least one piston (51) on at least one among the upper table (13) and the body (10) and at least one hole (52) that can be associated with the piston (51 ) on the other. When the piston (51) is aligned with the said hole (52), it extends into the hole (52) and fixes the upper mold (22) against the lower mold (21 ).

There may also be at least one spring assembly (60) on the upper table (13) strictly lean the upper mold (20) against the lower mold (21 ). The said spring assembly (60) creates a compressive force to lean the upper mold (22) against the lower mold (21 ) by taking power from the upper table (13). At least one air cushion (61) may also be positioned between the upper mold (22) and the upper table (13). This air cushion (61) provides better compression of the mortar in the mold (20).

With all this structure, the forming process of a vitrified product such as a sink is carried out by subjecting the sludge between a lower mold (21 ) and the upper mold (22) to pressure. During this process, the need for additional movement units in the casting machine (1 ) is eliminated by making the lower mold (21 ) and the upper mold (22) by the movement mechanism (30) operated according to the worm gear shaft (34) principle. This movement mechanism (30) eliminates the additional costs caused by the hydraulic movement units in the casting machines (1) known in the art. In addition, the manufacturing and assembly processes in the casting machine (1 ) are reduced.

The scope of protection of the invention is specified in the attached claims and cannot be limited to those explained for sampling purposes in this detailed description. It is evident that a person skilled in the art may exhibit similar embodiments in light of the above-mentioned facts without departing from the main theme of the invention.
