Problems solved by technology

[0002] In injection molding, when the three-plate mold structure mold is formed, the waste material of the point gate runner can be automatically stripped on the mold, and the small pull rod can be pulled through the fixed plate to pull the stripping plate to remove the waste material of the runner from the pull rod installed on the panel. The waste material of the runner will come out, let it fall off automatically, and realize the automatic production of the mold. However, with the different plastic materials, many plastics sometimes stick to the mold after being demoulded from the mushroom head of the pulling rod on the panel. If the runner plate cannot fall off, it will cause the failure of demolding the entire runner waste, which will make it difficult to continue the working cycle of the mold. Therefore, it is necessary to design an automatic material removal auxiliary mechanism for this practical production problem. to solve the above problems

Abstract

The invention discloses a front mould automatic shooting material mechanism of an injection mold of a three plates mold. The front mould automatic shooting material mechanism of the injection mold ofthe three plates mold is used to solve the problem of incompletely shedding of a runner waste material in demolding on the three plates. The problem that various plastic waste materials adhere on a runner plate is aimed to be carried out to reliably demould by the front mould automatic shooting material mechanism. The situations that various plastic automatically dropped off the runner plate and is not adhered to the runner plate are realized, and the function of mould automatic production is ensured. The front mould automatic shooting material mechanism is reasonable in design, compact in structure, stable in work, safe, reliable, and convenient to use.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to an automatic spring material mechanism for a front mold of a three-plate mold injection mold. Background technique [0002] In injection molding, when the three-plate mold structure mold is formed, the waste material of the point gate runner can be automatically stripped on the mold, and the small pull rod can be pulled through the fixed plate to pull the stripping plate to remove the waste material of the runner from the pull rod installed on the panel. The waste material of the runner will come out, let it fall off automatically, and realize the automatic production of the mold. However, with the different plastic materials, many plastics sometimes stick to the mold after being demoulded from the mushroom head of the pulling rod on the panel. If the runner plate cannot fall off, it will cause the failure of demolding the entire runner waste, which will make it dif...
