Rubber buffer ring manufacturing pressing mold

Abstract

The invention discloses a rubber buffer ring manufacturing pressing mold. The rubber buffer ring manufacturing pressing mold comprises a cylinder core, a sleeve mold, an upper mold and a lower mold; the cylinder core, the sleeve mold, the upper mold and the lower mold surround to form a mold cavity formed by a rubber buffer ring; the upper mold and the lower mold are oppositely arranged; the cylinder core is upwards projected from the top surface of the lower mold; the sleeve mold coats the outer side of the cylinder core, and is supported between the upper mold and the lower mold; a circular through hole is formed in the middle part of the upper mold; the through hole is the same in upper and lower inner diameters; the top end of the cylinder core is projected in the circular through hole; the top surface of the lower mold is upwards projected with a first boss with a conical side surface; a groove is recessed in the bottom surface of the sleeve mold, and is matched to coat the first boss; the bottom surface of the upper mold is projected with an annular second boss; the second boss is matched to project in the mold cavity; the top surface of the sleeve mold is projected with an annular third boss; and the third boss coats the outer side of the second boss. The rubber buffer ring manufacturing pressing mold has the advantages of easiness in product taking, convenience for exhausting, avoidance from product working surfaces, convenience for glue filling and easiness in mold installation and dismounting.

Description

technical field [0001] The application relates to a compression mold for making a rubber buffer ring. 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 affected, and it is not easy to remove the rubber...

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
