Abstract

The invention relates to the manufacture of rubber technical products and is intended for the manufacture of endless V-belts. The purpose of the invention is to improve the quality and facilitate their discharge. For this, annular grooves with inclined side walls are made in the upper 1 and lower 2 plates. The annular liners 3 and 4 are provided on the ends with conical protrusions for the annular grooves of the plates 1 and 2. In the base of the annular grooves of the lower plate 2 there are holes 9 for the fingers of the form reloading device to enter. Ring grooves 3 and 4 are installed in the slots of plates 1 and 2. In the process of pressing, the belts are completely formed. When the mold is opened, the ring belts remain on the ring liners. 1 hp f-ly. 3 il.

FIG. one

The invention relates to the manufacture of rubber technical products and is intended for the manufacture of endless V-belts.

The purpose of the invention is to improve the quality and facilitate the discharge of belts.

FIG. 1 shows the form in the closed state; in fig. 2 - the same, with an open top plate; in fig. 3 - the same, with open top and bottom plates.

the form is closed. Forms are piled up and placed in a press and vulcanization unit (not shown).

During the pressing process, the upper plate 1 presses the compression layer 11 in the direction of the blanks 10, as a result of which the belts 12 are completely formed.

After vulcanization, the mold is opened to raise the upper plate 1 and lower the lower plate 2. Ring liners 3 and

The form contains the upper 1 and lower 2 4 4 with ready-made belts 12 coming to the shells and concentrates of the ejection of ready-made belts located concentrically in them. Dacres inserts 3 and 4, which form the upper and lower surfaces of the belt. In the upper 1 and lower 2 plates there are annular grooves 5-8 with inclined lateral.-Belts at unloading, walls.

The grooves of plates 1 and 2 have a trapezoid shape in cross section, in which the angles of inclination of the surface are different due to the size difference

The next cycle is repeated.

Invention Formula upper and lower surfaces of the belt. Kol1. A mold for making endless V-belts containing the top and Integral liners 3 and 4 are made on top-20 bottom plates and concentrically located with conical protrusions, corresponding annular liners that form the grooves of the upper 1 and lower 2 plates. The upper and lower surfaces of the belt are different. the slots are lowering so that, in order to increase the plate 2, there are holes 9 for inserting belts, in the upper and lower plates of the fingers of the form reloading device (not 25 circular grooves with inclined shown). Side walls and annular inserts. about at once. They are made with conical protrusions on the torus. In grooves 5 and 6, annular rings are installed to interact with the annular grooves 3 and 4. In the resulting cavities. between the bottom plate 2 and the ring inserts 2. The form according to claim 1, wherein Breathes 3 and 4 place a part of the blank 30, in order to facilitate the unloading of products, 10, consisting of a stretch layer and force-in bases of the annular grooves of the lower Pligo layer, and a blank of compression layer 11. Then through holes are made. the form is closed. Forms are piled up and placed in a press and vulcanization unit (not shown). During the pressing process, the upper plate 1 presses the compression layer 11 in the direction of the blanks 10, as a result of which the belts 12 are completely formed. After vulcanization, the mold is opened to raise the upper plate 1 and lower the lower plate 2. Ring liners 3 and 4 with ready-made belts 12 are fed to a device for pushing out ready-made belts. Durham when unloading The next cycle is repeated. The shape design prevents damage to the surface and dimensions of the finished Invention Formula FIG. 2 FIG. 3
