Problems solved by technology

[0002] Existing joining dies are widely used, and are generally used in the butt joint of dense rubber sheets. Since the burr on the periphery of the product needs to be trimmed after the butt joint operation, a large amount of manpower is required, and the thickness of the burr of the vulcanized product is difficult to control. There are flashes and burrs, which make subsequent trimming difficult, product quality is not easy to control, the entire production and processing cycle is long, and production efficiency is low

Abstract

The invention discloses a trimming-free joint mold and application thereof. The trimming-free joint mold is formed by four molds in butt joint; after the joint surfaces of the four molds are in butt joint, a product has no need to be trimmed or deburred manually, so that the manpower is saved, and the productivity is improved; and by applying the trimming-free joint mold to jointing the product, the quality of the finished product is controllable, the production processing period is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to molds, in particular to a trimming-free joining mold. Background technique [0002] Existing jointing dies are widely used, and are generally used in the butt joint of dense rubber sheets. Since the burr on the periphery of the product needs to be trimmed after the butt joint operation, a large amount of manpower is required, and the thickness of the burr of the vulcanized product is difficult to control. There are flashes and burrs, which make subsequent trimming difficult, product quality is not easy to control, the entire production and processing cycle is long, and production efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a trimming-free joining die for direct molding without trimming and its application. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a trimming-...
