Problems solved by technology

[0005] The object of the present invention is to provide a switchable composite mold for injection molding machine, to solve the problem that the current existing injection molding machine mold proposed in the above background technology can only process one piece or a set of the same product at a time, and the production efficiency is relatively low. It is not enough to meet the growing demand now; it is not convenient enough for later maintenance, and there is no way to easily replace the molds with different fixed mold slots to produce products of different specifications; at the same time, during injection molding, due to EMC in The reaction speed is accelerated at high temperature, resulting in a relatively short gelation time of EMC and poor fluidity. When the cavity is not completely filled, the viscosity of EMC will rise sharply, and the flow resistance will also increase, so that a good EMC cannot be obtained. filling, thus forming a problem of unfilled tendencies

Abstract

The invention discloses a switching type composite mold for ab injection molding machine. The switching type composite mold comprises a base, a side edge plate is fixedly installed at the upper end of the base, a fixed plate is fixedly installed at the upper end of the side edge plate, a shell body is fixedly installed on the right side of the side edge plate, a feeding port is fixedly installed at the upper end of the shell body, an injection molding head is fixedly installed at left end of shell body, and mold bodies is fixedly installed below fixed plate. According to the switching type composite mold, the plurality of sets of mold bodies are arranged, switching can be controlled in the injection molding process, the time is saved, the production efficiency is improved, and the upper mold and the lower mold can be independently disassembled and assembled according to different production requirements; a turbocharger is arranged, sufficient pressure can be effectively provided for the injection molding process of the injection molding head, the injection molding speed is guaranteed, the situation that injection molding in the mold is insufficient, and consequently a finished product is hollow and not formed is avoided; and an evaporator is arranged, the gelling time can be delayed, and the cooling waiting time can be shortened.

Description

technical field [0001] The invention belongs to the technical field of injection molding machines, and in particular relates to a switchable composite mold for injection molding machines. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The injection molding function The plastic is heated and high pressure is applied to the molten plastic, causing it to shoot out and fill the mold cavity. [0003] At present, the existing injection molding machine molds can only process one piece or a set of the same product at a time, and the production efficiency is low, which is not enough to meet the growing demand; it is not convenient enough for later maintenance, and there is no way to quickly It is conv...
