Anti-deviation injection molding device with magnetic block positioning structure

Abstract

The invention relates to the technical field of injection molding equipment, and discloses an anti-deviation injection molding device with a magnetic block positioning structure. The anti-deviation injection molding device with the magnetic block positioning structure comprises a rotating shaft, a fixed mold and a fixed block, wherein the fixed block is located on the right side of the fixed mold. Through the arrangement of movable molds, a magnetic block I and a movable electromagnetic device I, a circular ring formed by the five movable molds can be divided into four areas, namely an injection area, a pressure maintaining area, an unloading area and a mold closing area, the direction of current introduced into the movable electromagnetic device I is switched, the direction of a magnetic field is changed, and then adsorption and boosting of the magnetic block I are completed; and when the movable molds are positioned and boosted during adsorption, the movable molds are pushed to rotate, and the fixed mold after injection is pushed to the pressure maintaining area, so that injection and pressure maintaining cooling procedures are separated and do not interfere with each other, on one hand, the injection molding efficiency is improved, on the other hand, the pressure maintaining time is prolonged, a plastic part is ensured to have enough time for cooling and shaping, and the situation that deformation after unloading is caused due to insufficient cooling time of the plastic part is prevented.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to an anti-deviation injection molding device with a magnetic block positioning structure. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding machines are the main molding equipment for making plastics into various shapes of plastic products using plastic molding molds. During production, plastic raw materials are in the injection molding machine. Heating and melting in the middle, and then injecting the melted plastic into the mold, cooling and forming, but there are some shortcomings in the use of the injection molding device, as follows: [0003] During the injection process, the mold needs to be clamped first, and then the injection head of the injection machine should be aligned with the injection port of the mold. However...

Problems solved by technology

[0003] During the injection process, the mold needs to be clamped first, and then the injection head of the injection machine should be aligned with the injection port of the mold. However, during this process, the mold needs to be positioned precisely. Offset with the core, causing the edge of the plastic part to overflow, the plastic is deformed and burrs are formed. Since the injection head is directly connected to the injection molding machine, the inertia force is relatively large during the contact process between the mold and the injection molding machine. Once the injection head and the injection port are docked Deviations will cause collision or friction between the injection head and the mold, which will cause the injection head to wear out, or cause the injection head to break
