Novel threaded side core-pulling injection mold

Abstract

The invention discloses a novel threaded side core-pulling injection mold in the technical filed of injection molds. The novel threaded side core-pulling injection mold comprises a fixed mold, a cavity is formed in the left side of the fixed mold, an ejection plate is slidably connected to the inner wall of the cavity, a reset mechanism of the ejection plate is connected to the right side of the fixed mold, an L-shaped mounting frame is fixedly connected to the bottom of the left side of the fixed mold, and an electric cylinder is fixedly connected to the side surface of the L-shaped mountingframe. According to the novel threaded side core-pulling injection mold, by arranging a threaded core, a U-shaped mounting frame, connecting rods, a moving plate, a pushing rod, supporting springs, alinkage plate, a threaded sleeve, a supporting rod, a follow-up gear, a L-shaped linkage plate, driving teeth and a pulling pin, in the demolding process, workers have no need manually demolding partson the other side, automatic demolding of injection-molded parts in the lateral core pulling process is achieved, and only the molded parts subjected to demolding need to be received so that the workers can conveniently demold the injection-molded parts, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a novel thread side core-pulling injection mold. Background technique [0002] When forming a plastic part with threaded holes on the side, it is necessary to use a threaded side core. Before the plastic part is demolded, the threaded side core is pulled out, and then the plastic part is ejected from the cavity. The core pulling of the threaded core has two actions, the rotary motion of the threaded core and the linear movement, so as to complete the thread removal action. [0003] In the prior art, there are some invention patents for threaded side core-pulling injection molds. The Chinese patent application number is 201710064713.8, which discloses a new type of threaded side core-pulling injection mold. The connecting screw is fixed; the main core passes through the fixed template; the screw shaft passes through the fixed template; the rack nut is sleeved on the screw...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a new thread side core-pulling injection mold to solve the problem that the thread side core-pulling injection mold in the prior art cannot automatically complete the process of side core-pulling mold opening in the above-mentioned background technology. The detachment of the molded part needs to be pulled sideways. After the completion of the core pulling, the staff manually pushes the molded part removal mechanism to complete. The staff pushes the part while pushing the part, and the other side needs to take the molded part. The operation is more troublesome and reduces the work efficiency.
