Rubber buffer ring press die

Abstract

The invention discloses a rubber buffer ring press die which comprises a cylinder, a sleeve ring, an upper die and a lower die which define a die cavity used for rubber buffer ring molding. The upperdie and the lower die are oppositely arranged, the cylinder extends in a protruding manner from the top face of the lower die upwards, the sleeve ring is arranged on the outer side of the cylinder ina sleeving manner and is supported between the upper die and the lower die, a guide hole is formed in the middle portion of the upper die, the top end of the cylinder extends in a protruding manner into the guide hole and is in taper face fit with the inner wall of the guide hole, the top end of the lower die extends in a protruding manner to form a first boss with a taper side face, the bottom end of the sleeve ring is matched with the first boss to form a step part in a sinking manner, the bottom face of the upper die extends in a protruding manner to form a second boss, the bottom face of the second boss is formed above the die cavity, and the second boss and the top end of the sleeve ring are in slope fit. The rubber buffer ring press die has the beneficial effects that a product is easily taken out, exhausting is convenient, the working face of the product is avoided, sizing material filling is facilitated, the die is easy to mount and demount, the product appearance is guaranteed, and trimmings are easily removed.

Description

technical field [0001] The application relates to a compression mold of a rubber buffer ring, which is used for an idler roller of a belt conveyor. Background technique [0002] The rubber buffer ring is used for the idler roller of the belt conveyor. It is a light buffer part, and its hardness is generally about 70 degrees Shore. Follow-up when working, multiple joints work, do not bear excessive external force, and the strength requirement is not high, generally 10-12Mpa. [0003] Traditional molds for making rubber buffer rings generally use two-part molds, which include upper and lower molds and a cylinder in the middle. Although its cost is low, there are at least the following problems: [0004] (1) It is inconvenient to take out the product; [0005] (2) The exhaust of the lower mold is not good; [0006] (3), did not avoid the working surface of the product; [0007] (4), it is not convenient to fill the rubber; [0008] (5) The appearance of the product is aff...

AI Technical Summary

Problems solved by technology

[0004] (1) It is inconvenient to take out the product;

[0005] (2) The exhaust of the lower mold is not good;

[0006] (3), did not avoid the working surface of the product;

[0007] (4), it is not convenient to fill the rubber;

[0008] (5) The appearance of the product is affected, and it is not easy to remove the rubber edge

[0009] Therefore, traditional molds are difficult to meet actual needs
