Novel injection mold for inverse buckle demolding

Abstract

The invention discloses a novel injection mold for inverse buckle demolding. The novel injection mold comprises a movable mold body and a fixed mold body and further comprises an inclined guide block,a mounting seat, a sliding table, a sliding plate, a driving cylinder and a mold core. The sliding table and the driving cylinder are fixedly arranged on the mounting seat. A linear chute is formed in the sliding table. The sliding plate is movably clamped in the linear chute. The driving cylinder is connected with the sliding plate. The mold core is installed on the sliding plate. A hollow cavity is formed in the mold core, and a core column is arranged in the cavity. The front end of the core column is of a conical structure, and sliding rails are arranged at the front end of the core column. A movable insert is movably clamped to each sliding rail. The movable inserts penetrate through the inside of the mold core in the radial direction of the core column. A T-shaped groove is formed in the inclined guide block. The tail end of the core column is movably clamped in the T-shaped groove. According to the novel injection mold, the movable inserts are arranged on the mold core and matched with the core column in the mold core, so that inverse buckle demolding of a pipe opening of a shell of an air filter element device is ingeniously realized, the production efficiency is high, thedemolding speed is high, the injection molding quality is good, the yield is high, and the use effect is good.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a novel injection mold with an undercut. Background technique [0002] Injection molds are important technological equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in industrial sectors such as aviation, aerospace, electronics, machinery, ships and automobiles, the scope of application of injection molds is increasing. more extensive. Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and melted plastic into a mold cavity under high pressure from an injection molding machine, and after cooling and solidifying, a molded product i...

AI Technical Summary

Problems solved by technology

[0004] , to solve the problem that there is an undercut at the nozzle of the air filter housing, and the conventional method cannot be used for demoulding, and strong demoulding will easily lead to tearing of the nozzle and low yield rate
