Preheat rotary injection molding die mechanism for injection molding machine

Abstract

The invention discloses a preheat rotary injection molding die mechanism for an injection molding machine. The injection molding die mechanism comprises a rack, wherein a main vertical plate is fixedat the top of the rack; two vertical fixing plates are fixed at the top of the roof of the rack and at the rear part of the right side of the main vertical plate; heat plates are fixed on two oppositewall surfaces of the two vertical fixing plates; a transverse main shaft is hinged with the center of the main vertical plate; and the right end of the traverse main shaft extends out of the main vertical plate, and a rotary plate is fixed at the right end of the transverse main shaft. According to the preheat rotary injection molding die mechanism, a plurality of left injection molding dies arearranged on the rotary plate, after injection molding in one left injection molding die is completed, the rotary plate is immediately rotated to the next left injection molding die for injection molding, continuous injection molding is realized along with good effect and high efficiency, and the left injection molding dies and right convex die blocks to be about to injection molding can be preheated to ensure the temperature for the dies during injection molding, so that the injection molding effect can be ensured.

Description

Technical field: [0001] The invention relates to the technical field of injection molding equipment, in particular to a preheating rotary injection mold mechanism for an injection molding machine. Background technique: [0002] In the existing small injection molding machines, it generally only has one injection mold. After injecting the injection material into the injection mold through the injection nozzle, the injection mold needs to be opened to take out the material, and then the subsequent injection molding is very troublesome and inefficient. continuous production; [0003] At the same time, before injection molding, in order to ensure the injection molding effect, the mold needs to be heated, and the existing mold generally needs to be heated before installation, which is very troublesome, especially in winter, the heating time is long, and after one injection molding is completed, the next For one thing, when the temperature of the mold is not enough, it needs to b...
