Problems solved by technology

[0002] In the injection mold, 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 pull the waste material of the runner from the material installed on the panel. The runner waste is released from the rod to let it fall off automatically to realize the automatic production of the mold. However, with the different plastic materials, many plastics sometimes stick to each other after being demoulded from the mushroom head of the pull rod on the panel. If it cannot fall off on the runner plate, it will cause the demoulding failure of 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 problem

Abstract

The invention provides an injection mold and an application method thereof. The injection mold comprises a three-plate-mold injection mold front mold automatic ejecting mechanism for solving the problem of halfway falling in the three-plate upper runner waste falling; the mechanism performs reliable demolding for the problem of variable plastic runner wastes attached on runner plates, and can realize automatic falling of various plastic from the runner plates without bonding on the runner plates to guarantee the mold automatic production function; and the 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 mold mechanism design, in particular to an injection mold and a use method thereof. Background technique [0002] In the injection mold, 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 pull the waste material of the runner from the material installed on the panel. The runner waste is released from the rod to let it fall off automatically to realize the automatic production of the mold. However, with the different plastic materials, many plastics sometimes stick to each other after being demoulded from the mushroom head of the pull rod on the panel. If it cannot fall off on the runner plate, it will cause the demoulding failure of the entire runner waste, which will make it difficult to continue the working cycle of the mold. Therefore,...
