Injection molding machine of automobile injection mould

Abstract

The invention discloses an injection molding machine of an automobile injection mould. The injection molding machine comprises a charging barrel, a screw rod, a driving mechanism, a bracket and a control device, wherein the charging barrel comprises two parts including a charging barrel heating chamber and a charging barrel plastifying chamber; the charging barrel covers the screw rod; the inner diameter of the charging barrel heating chamber is 0.3mm less than the outer diameter of the head of the screw rod so that the charging barrel heating chamber can be tightly clamped by a screw rod plug; the charging barrel is fixedly ejected against the bracket; the front end of the charging barrel heating chamber is connected with a nozzle; an electric heating coil covers the screw rod; the electric heating coil is connected with a heating controller; the heating controller is fixedly arranged on the bracket; the charging barrel is provided with a feeding opening and solid plastic enters the charging barrel from a hopper. The injection molding machine of the automobile injection mould has the beneficial effects that the injection molding efficiency can be improved, the injection capacity range is large and a pouring gate trace is not generated.

Description

technical field [0001] The invention relates to the field of automobile injection molds, in particular to an injection molding machine for automobile injection molds. [0002] Background technique [0003] Injection mold injection molding machine is divided into vertical injection molding machine and horizontal injection molding machine. The injection direction of the vertical injection machine is downward and the mold clamping direction is upward. The injection method adopts the plunger method, which occupies a small area and is easy to install. The disadvantages The injection speed is uneven, the internal stress of the plastic part is large, and the efficiency is low. Horizontal injection machines are widely used at present. The mold is installed horizontally on the injection machine, and the injection and mold clamping directions are on the same horizontal line. The injection method is generally a screw. The advantage is low cost, easy to operate, the plastic parts can fa...

Problems solved by technology

[0002]Injection mold injection molding machine is divided into vertical injection molding machine and horizontal injection molding machine. The method adopts the plunger method, which occupies a small area and is easy to install. The disadvantage is that the injection speed is uneven, the internal stress of the plastic part is large, and the efficiency is low. Horizontal injection machines are widely used at present. The mold is installed horizontally on the injection machine. On the same level as the mold clamping direction, the injection method is generally screw type, which has the advantages of low cost, easy operation, plastic parts can fall by themselves after being ejected, high production efficiency, and occupies a large area. In addition, there are angle type injection molds. Injection machine, the gas injection direction is downward, and the injection method is plunger type. Its structure is simple, and the plastic parts can automatically fall after the mold is opened, but the insert is inconvenient to place and easy to tilt. Now the automobile injection mold is developing towards process and production. And gate traces are not allowed, improving the quality of injection molding machines has always been a concern of the injection mold industry
