Material removing device of injection mold

Abstract

The invention belongs to the field of gel cleaning, and particularly relates to a material removing device of an injection mold. The device comprises a pressing-in mechanism, a pulling-out mechanism and a screw, wherein the pressing-in mechanism comprises a pressing rod, a reset rod, a reset spring, a guide sleeve and a heating sleeve; the pressing rod is connected with the reset rod; the guide sleeve is arranged at the tail end of the reset rod; one end of the reset spring is connected with the head end of the reset rod, and the other end of the reset spring is connected with the head end ofthe guide sleeve, and the reset spring sleeves the reset rod; the tail end of the guide sleeve is connected with a heating tube; and the heating tube is connected with a power supply wire. The specialtool is designed to replace inefficient tools such as nipper pliers for clamping or round rods for knocking, so that the cleaning efficiency is improved, the damage to the mold is reduced in the process of removing the gel, and the service life of a main runner bush is prolonged; and the product is developed and produced, so that theoretical practical experience can be provided for development ofother similar products.

Description

technical field [0001] The invention belongs to the field of coagulation material cleaning, and in particular relates to a coagulation material removal device for an injection mold. Background technique [0002] The main channel is the main passage for the molten plastic raw material to flow into the mold cavity. During the mold trial process of the injection mold, due to reasons such as unreasonable injection molding process parameters or mold design defects, the condensate often remains in the main channel and cannot be cleaned. Once this happens, the inflow channel will be blocked, affecting the trial and production. [0003] In actual production, needle-nose pliers are often used to pick, or the method of knocking with thin metal rods is time-consuming and laborious, and it is easy to cause damage to the main channel bushing, affect the use of the mold, and cause certain economic losses. Specifically in: [0004] 1. Due to the relatively narrow outlet of the main chann...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the relatively narrow outlet of the main channel bushing, it is difficult for the needle-nose pliers to penetrate into it, and it is impossible to effectively clamp the condensate. Even if the partial material is clamped, the cooled condensate is relatively brittle, and the process of pulling it outward It is easy to cause the fracture of the aggregate, and the residual material is left deep in the main channel, which is more difficult to remove

[0005] 2. Since the condensate is closely attached to the side wall after cooling, the friction force is very large. It is necessary to use a thin metal rod to penetrate into the main channel to knock it out. It requires a lot of force, which may easily cause the metal rod to scratch the inner wall and affect the subsequent injection molding production.
