Staggered injection molding machine provided with screw cylinder cavity

Abstract

The invention discloses a staggered injection molding machine provided with a screw cylinder cavity. A screw cylinder main body used for heating raw materials is installed on a workbench at one side of an injection molding machine body, wherein the screw cylinder main body further comprises a first screw cylinder shell and a second screw cylinder shell, and the lower portion of the first screw cylinder shell is fixed on the workbench at one side of the injection molding machine body through bolts, so that the first screw cylinder shell is installed and fixed on the upper end surface of the injection molding machine body, and conveying transmission of feeding screw rods in conveying cavities is guaranteed. According to the staggered injection molding machine provided with the screw cylinder cavity, the structure of a screw cylinder of an injection molding machine is improved so that the interior of the screw cylinder can be conveniently cleaned and maintained when the screw cylinder is maintained, the feeding screw rods can be conveniently moved out, and meanwhile, the installation efficiency of heating plates is improved due to improvement of the shapes and the installation mode of the heating plates.

Description

technical field [0001] The invention relates to the technical field of injection molding machine screw barrels, in particular to a staggered injection molding machine with a screw barrel cavity. Background technique [0002] During the use and maintenance of the injection molding machine, there will inevitably be foreign matter in the raw materials. Over time, it will inevitably cause wear on the inner wall of the inner cavity of the screw barrel of the injection molding machine, and at the same time cause damage to the feeding screw, and then the injection molding machine needs to be repaired. The screw barrel is disassembled for cleaning and maintenance. [0003] For example, the comparative document application number: CN200810027245.8, authorized announcement date: 20101117, an injection mechanism of an injection molding machine, including an extrusion mechanism, an injection device and at least two moulds, is characterized in that the injection device is connected by at...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a staggered injection molding machine with a screw cavity, so as to solve the existing injection molding machine screw barrels on the market proposed by the above-mentioned background technology. When in use, the screw barrel structure is integrated. Formed single screw barrel structure, when the screw barrel needs to be repaired, the entire screw barrel needs to be removed, and it is not convenient to remove the feed screw, and a heating plate is usually fixed outside the heating screw barrel, but when installing the heating When installing the heating plate, it is necessary to fix the heating plate to the outside of the screw barrel and connect the wires one by one. The installation process is cumbersome and time-consuming.
