SPECIFICATION

A VITRIFIED PRODUCT CASTING MACHINE

TECHNICAL FIELD

The present invention relates to a vitrified product casting machine for production of vitrified products.

PRIOR ART

In casting processes of vitrified products like wash-basin, shower tray, vitrified product casting machine can be used having multiple mold system which casts pluralities of vitrified products onto a machine. Thanks to vitrified product casting machines, products with predetermined dimensions and predetermined aesthetic can be produced, and production can be standardized.

However, in these vitrified product casting machines, molds are positioned orthogonally by means of a hanger system. In this case, in said vitrified product casting machine, only the production of vitrified products which must be taken from the mold at 90 degrees can be realized. For the special vitrified products which must be taken in the horizontal position, a new vitrified product casting machine must be provided.

In the known state of the art, casting machines, provided for vitrified products which must be taken in the horizontal position, can realize pressing by means of a mold. This leads to inefficiency in terms of labor, time and cost.

In the literature, there is the patent application with application number US5156855. Said application relates to a device used in die casting of ceramic goods like sanitary systems. According to the invention, during molding, the machine is bent by a hydraulic unit and efficiency of molding is increased and the excessive raw material is discharged.

Besides, closet technology has also changed in time. Today, the vitrified products known as smart closet have more complex recesses and protrusions when compared with known classical closets. During production of these recesses and protrusions in the presently used vitrified casting machines, the mud/liquid mortar cannot be completely placed in the mold and a gapped structure occurs. In this case, discard proportion increases, production cost increases, and time losses occur.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , a representative perspective view of the subject matter casting machine (10) is given. Accordingly, said casting machine (10) particularly provides the production of vitrified products by injecting mud/liquid mortar into the mold. The casting machine (10) has at least one casting unit (30) and at least one main body (20) for carrying said casting unit (30). Said casting unit (30) is bedded in said main body (20) in a manner at least partially rotating around itself particularly for providing molding of complex structured vitrified products. The casting unit (30) is rotated by driving at least one rotation shaft (52), positioned on the casting unit (30), by at least one drive element (60) positioned on the main body (20). In a possible embodiment of the present invention, there are two rotation shafts (52) and said shafts (52) are bedded to the main body (20) from the two mutual sides of the casting unit (30).

In Figure 2, a representative exploded view of the casting unit (30) positioned in the subject matter casting machine (10) is given. Accordingly, the casting unit (30) comprises at least two lateral molds (31) positioned mutually, at least one lower mold (34) and at least one upper mold (35) associated with said lateral molds (31) vertically, in order to form a closed volume for molding of the vitrified product. Moreover, the casting unit (30) has at least one rear mold (32) and provides mud/liquid mortar input into the mold by said rear mold (32). The molds are configured to be one each parts of the surface which encircles the form desired to be produced at the inner part thereof. At least one flow line (33) is positioned on the rear mold (32), and the flow of the molding material into the mold is provided. In the casting unit (30), the mutual molds are moved with respect to each other for molding of the vitrified product and for removing of the vitrified product from the mold. The lateral molds (31) are positioned so as to slide on at least one guide (51). Said guide (51) is connected to at least one each carriage bodies (50) positioned at two mutual sides of the casting unit (30) from one each ends. In a possible embodiment of the present invention, the two lateral molds (31) are moved hydraulically in the horizontal plane on the guide (51). The lower mold (34) and the upper mold (35) are moved vertically with the movement items (not illustrated in the figures) positioned on the main body (20). The hangers (41), positioned on the upper mold (35), provide the movement items to carry the upper mold (35). The lower mold (34) and the upper mold (35) are separated from the movement items in order to provide rotation of the casting unit (30) around itself. The lower mold (34) and the upper mold (35), separated from the movement items, are configured to be able to move together with the casting unit (30).

There are at least one each locks (39) for providing positioning of the lower mold and the upper mold (35) in the casting unit (30). Said locks (39) enter into at least one each lock housings (40) provided on the lateral molds (31) and provide the lower mold (34) or the upper mold (35) to move together with the casting unit (30) in the vertical plane. In the preferred embodiment of the present invention, there are at least four each locks (39) and lock housings (40) for the lower mold (34) or for the upper mold (35), and they are moved pneumatically towards the lock housing (40). Moreover, the lower mold (34) and the upper mold (35) have at least one each tabs (37). Said tabs (37) engage to at least one tab housing (38) provided on the lateral molds (31). Thanks to this, the movement of the lateral molds (31) in an independent manner from each other is prevented and a rigid structure is obtained. In the preferred embodiment of the present invention, at least one each air pads (36) are positioned on the molds. Said air pads (36) expand pneumatically and compensate the assembly gaps which may occur when the molds are joined. The movable items, provided in the casting machine (10), are connected to at least one control unit (not illustrated in the figures). By means of said control unit, approaching of the molds to each other, diverging of the molds from each other and rotating of the casting unit (30) at least partially are programmed and controlled by the user. The control unit is preferably an arduino programming platform.

In a possible embodiment of the present invention, when closet (70) casting is desired to be realized in the casting machine (10), the lateral molds (31) and the rear mold (32) move horizontally and are rested to each other. After joining horizontally, the lower mold (34) and the upper mold (35) are rested to the lateral molds (31) by means of vertical movement in the vertical plane. As the lower mold (34) and the upper mold (35) are rested to the lateral molds (31), the tabs (37) enter into the tab housings (38) and the lock (39) is engaged to the lock housing (40). After the lower mold (34) and the upper mold (35) are joined with the lateral molds (31), they are separated from the movement items. In this case, the casting unit (30) has connection with the casting machine (10) only through the rotation shaft (52). The rotation shaft (52) can be rotated by the drive element (60) at a predetermined amount. Molding material is injected through the flow line (33) for molding of the closet (70) and the production is realized. In order to provide placement of the mud/liquid mortar, which will form the closet (70), into the mold without gaps during casting of the closet (70), the casting unit (30) is rotated at a predetermined amount by the drive element (60). In order to remove the closet (70) from the mold after casting, the tabs (37) and the locks (39), provided on the lower mold (34) and on the upper mold (35), are separated from the lateral molds (31) and are diverged from the lateral mold (31) in the vertical plane. Afterwards, the closet (70) can be held from the base (71) by a robot arm (not illustrated in the figures) and removed. Or if an additional adhesion process is needed to be realized to the rim (72) part of the closet (70), the closet (70) can be rotated and adhesion can be realized such that the closet (70) weight is above.

With all these embodiments, casting angle, washing angle, discharge angle can be easily provided during casting thanks to the rotation characteristic of the casting unit (30). Besides, foot casting and casting over the rim (72) are realized by a single casting machine (10), and an extra product cost is prevented. Moreover, by means of the rotation characteristic, the heavy part is provided to be above in the production processes of the closet (70) with adhesion where production cannot be realized in a single step. By means of this, the discard proportion is reduced, production cost is reduced and high production amount is obtained in a short time.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
