Abstract

The invention relates to the technical field of extrusion injection molding machines, to solve the problem of low production efficiency of an injection molding machine in the prior art. In particular, the invention relates to an extrusion feeding mechanism, comprising a pushing assembly, a sliding assembly and an extrusion assembly, wherein the pushing assembly drives the extrusion assembly for straight reciprocating motions through the sliding assembly; the pushing assembly comprises a first support frame, a first oil cylinder mounted on the first support frame, and a connecting plate capable of doing straight reciprocating motions under the push of the first oil cylinder; a channel for the first support frame to pass is arranged on the connecting plate; the sliding assembly comprises a substrate and a sliding member; the first support frame passes through the connecting plate to be fixedly connected to the substrate. The invention also specifically relates to an extrusion injection molding machine, comprising the extrusion feeding mechanism, wherein two extrusion feeding mechanisms are arranged, each of which is disposed on each of two sides of an injection mold, and respectively correspond to a first injection molding port and a second injection molding port. The production efficiency of the current injection molding machine can be accelerated, and production costs can be saved.

Description

technical field [0001] The invention relates to the technical field of extrusion injection molding machines, in particular to an extrusion feeding mechanism and an extrusion injection molding machine. Background technique [0002] In recent years, plastic products have become more and more popular in people's daily life due to their excellent performance and cheap price. As a common model in the plastic processing industry, injection molding machines have also been widely used. [0003] Injection molding machine is a very traditional injection molding old product driven by an oil motor drive screw. It has been in circulation in the market for more than 30 years. The materials used for injection molding of injection molding machines are divided into raw materials and recycled materials. Raw materials It is directly produced by chemical synthesis methods, such as common PP, PE, ABS, etc. During the injection molding process, the injection molding machine heats the raw material...
