Problems solved by technology

[0002] Production figure 1 For the products with the structure shown in the figure, for the current plastic parts with undercuts in the entire circumference, mold engineers generally use inserts and sliders when designing plastic injection molds. This demoulding method is to pull the core out first. Part of the insert remains in the product. After the product and the insert are ejected together, the product and the insert are fixed on a special fixture, and the inserts are taken out manually, which is extremely inefficient. , it is a waste of manpower, the efficiency of production cannot be improved, and the quality is difficult to control

Abstract

The invention discloses a novel inner-circle complete backoff core-pulling mechanism, which comprises a core, a sliding block I, a sliding block II, a sliding head, a guide block, a connecting rod, a main body and a driving guide device, wherein the sliding block I and the sliding block II are matched at the front end of the guide block in a sliding manner; a complete circle is formed at the front ends of the sliding block I and the sliding block II; the rear end of the guide block is connected with the front end of the connecting rod; the front ends of the sliding block I and the sliding block II are pressed against the rear end of the core; the sliding head is sleeved outside the front ends of the sliding block I and the sliding block II and is fixed at the front end of the main body; an extended thin pipe is arranged at the rear end of the core; axial through holes are formed in the guide block and the connecting rod; the extended thin pipe sequentially passes through the axial through holes in the guide block and the connecting rod; the rear end of the extended thin pipe is connected with a limiting block; an opening slot is formed in the rear half part of the connecting rod; the limiting block is positioned in the opening slot; and the connecting rod is connected with the driving guide device. By the novel inner-circle complete backoff core-pulling mechanism, the core-pulling efficiency is improved, resources are saved, and the production efficiency is improved; and the novel inner-circle complete backoff core-pulling mechanism belongs to the technical field of dies.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a novel core-pulling mechanism with an inner-circle full circumference undercut. Background technique [0002] Production figure 1 For the products with the structure shown in the figure, for the current plastic parts with undercuts in the entire circumference, mold engineers generally use inserts and sliders when designing plastic injection molds. This demoulding method is to pull the core out first. Part of the insert remains in the product. After the product and the insert are ejected together, the product and the insert are fixed on a special fixture, and the inserts are taken out manually, which is extremely inefficient. , which is a waste of manpower, the efficiency of production cannot be improved, and the quality is difficult to control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel inne...
