It is to be understood that the present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The present disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

The present invention generally relates to the field of machine automation. The present invention particularly relates to an invertible curing ring mold device for power transmission V belts. Further the present invention relates to a method of assembling and disassembling of the invertible curing ring mold device for power transmission V belts. Advantageously, the present invention relates to an invertible curing ring mold device will reduce the worker ergonomics and will reduce the cycle time of assembling and dismantling. The dismantling of ring mold means taking the cured product out of the mold. In all the existing designs, the assembly and dismantling will be a separate process which was a time consuming and will create fatigue to the operator. To avoid this, the top and bottom rings was made identical. The top ring and bottom ring are interchangeable and to accommodate this change one label ring was introduced. In earlier designs the top and bottom rings will have product profile which restricts the possibility of interchanging the top and bottom mold.

In this new invention, the top and bottom rings were made flat and will not have product profile in it. Instead a label ring was introduced which will have product profile in it. This will enable the operator to assemble the product to the mold during dismantling process itself. This process combination of assembling and dismantling will reduce the cycle time by half and fatigue of the workmen by half. The below illustration shows step by step assembling and dismantling the mold.

Mold Construction: 1. The mold will have 6 parts. Top ring, Label ring, multiple middle rings, bottom rings, center shaft and bottom nut

2. One ring mold is an assembly of the six components.

3. The Label ring will have a portion of product profile on its bottom side.

4. The middle ring is designed in such a way that it will have product profile on top and bottom side. 5. Two middle rings will be placed one over another to form the profile of one product.

6. The top and bottom rings will be a flat ring and it will aid in closing the mold.

7. The center shaft is a round rod with one end will have hook to lift the mold and another end will have square thread to tight the mold.

8. The nut will be placed in the bottom ring. It is a loosed element. The nut will have square that to mate with the center shaft.

Mold assembly and dismantling steps:

9. Place bottom mold on the assembly table. The bottom ring will have a provision to hold the nut. Place the nut in that provision.

10. Place the middle rig over the bottom ring. Over the middle ring, place on uncured belt. The bottom ring will have half portion of the belt profile.

11. Place another middle ring over the uncured belt. When two middle rings assembled, the belt profile will be formed and uncured belt will seat inside the profile comfortably.

12. Repeat the assembly until the set of belt is over. After the last belt is placed over the middle ring, place the label ring. The label ring will have half portion of the belt. 13. Place the product indication label over the label ring and place the top ring over the label ring.

14. Insert the center shaft in the top ring center and pass it till it reaches the bottom ring. Tight the center shaft with the bottom nut. Tight until enough toque is achieved.

15. Lift the mold and place it inside the curing chamber.

Dismantling and assembling:

16. In this both dismantling and assembling will be at the same time.

17. Take the mold from the curing chamber once the curing is over.

18. After cooling process is completed, place the mold over the assembly table. 19. Loosen the center shaft and take the shaft out of the mold and keep it aside.

20. Remove the top ring and invert it and place it in the table. Since top and bottom rings are identical now the top ring will become bottom ring. Place the nut in the nut holding provision.

21. Remove the label ring and place it aside.

22. Remove the cured belt from the middle ring and place the uncured belt in the place of the cured belt. Take the middle ring with uncured belt and place it over the bottom mould without inverting.

23. Repeat this process until the last middle ring is assembled with uncured belt.

24. After the process is over, take the label ring and place it over the top middle ring.

25. Place the product indication over the label ring and take the bottom ring and place it over the label ring. Now the bottom ring will become top ring. 26. Insert the center shaft in the top ring center and pass it till it reaches the bottom ring. Tight the center shaft with the bottom nut. Tight until enough toque is achieved.

27. Lift the mold and place it inside the curing chamber.
