Front mold prior demoulding structure for injection mold

Abstract

The invention discloses a front mold prior demoulding structure for an injection mold. The front mold prior demoulding structure comprises a female mold plate and is characterized in that a male moldplate is arranged on the lower side of the female mold plate, a stripper plate is arranged on the upper side of the female mold plate, an upper fixed plate is arranged on the upper side of the stripper plate, a prior pulling plate component arranged between the female mold plate and the stripper plate, the female mold core of an injection molding product is arranged in the female mold plate, the male mold plate and the female mold plate are provided with mold locking devices, the prior pulling plate component is provided with a prior pulling insert, a guide positioning device and a limit mechanism are arranged between the female mold plate and the prior pulling plate component, and a forcible mold opening control structure is arranged among the female mold plate, the stripper plate and theprior pulling plate component. The front mold prior demoulding structure is simple in structure, capable of increasing product quality stability, stable in front mold prior demoulding, capable of favorably guaranteeing that the whole demoulding process is performed smoothly, simple and reliable in mechanism, capable of increasing product quality and production efficiency and suitable for being popularized.

Description

【Technical Field】 [0001] The invention relates to a first demolding structure of the front mold of an injection mold. 【Background technique】 [0002] In view of the structural characteristics of some injection molded products, the mold release process of the injection molding process involves the sequence of opening the female mold first and opening the male template and the female template to ensure product quality. The structure of the mold directly affects the safety of the production process and the stability of product quality. [0003] At present, the first demolding structure of the injection mold mainly relies on the elastic force of the spring to release the mold first, or some of it will be combined with the increase of the nylon rubber stopper and the expansion force after the locking rubber stopper is forced to open to realize the mold opening. The nylon rubber stopper is more durable Poor and insufficient stability, it will drop powder after damage, affecting the norm...

AI Technical Summary

Problems solved by technology

[0003] At present, the first demoulding structure of injection molds mainly relies on the elastic force of the spring to realize the first demoulding, or some will combine the addition of nylon rubber plugs to rely on the expansion force of the locked rubber plugs to force the opening to open the mold. The durability of nylon rubber plugs is relatively low. Poor and insufficient stability, it will drop powder after damage, affecting the normal production of the mold

Due to the fact that the spring is often stuck and the mold cannot be opened first, this structure seriously affects the quality of the product and the production efficiency
