Electric injecting table mechanism for double-lead-screw injection

Abstract

The invention discloses an electric injecting table mechanism for double-lead-screw injection. The electric injecting table mechanism comprises an injecting table fixed plate and an injecting table movable plate which are located on a base. The injecting table fixed plate is internally provided with a glue melting barrel. The injecting table fixed plate is provided with an electric driving device.A glue injecting screw and ball lead screws on the two sides of the glue injecting screw are arranged between the injecting table fixed plate and the injecting table movable plate. The glue injectingscrew and the ball lead screws are rotationally positioned in the injecting table movable plate. The glue injecting screw is inserted in the glue melting barrel in a penetrating mode. The electric driving device is connected with the glue injecting screw and simultaneously rotates with the ball lead screws. The injecting table fixed plate is provided with nuts. The free ends of the ball lead screws are in threaded connection with the nuts. The injecting table movable plate can linearly move along the base relative to the injecting table fixed plate. The electric injecting table mechanism fordouble-lead-screw injection is simple in structure, and large glue injecting force is obtained through only one servo motor.

Description

technical field [0001] The invention relates to an injection molding mechanism, in particular to an electric injection platform mechanism for twin-screw injection. Background technique [0002] At present, the injection mechanism of the electric injection station of the medium and large-scale injection molding machine in the market generally has a structure of three major plates.

[0002] At present, the injection mechanism of the electric injection station of the medium and large injection molding machine in the market generally has a structure of three major plates. The injection station part includes the front plate of the injection station, the movable The tie rod of the injection platform is fixed, the movable plate of the injection platform moves between the front plate of the injection platform and the tail plate of the injection platform, the pressure sensor is installed and fixed on the movable plate of the injection platform, the ball screw is fixed on the tail plate of the injection platform, the screw nut and the pressure sensor Fixed connection, the injection movement process is the rotation of the screw, pushing the nut and the movable plate to reciprocate to realize the injection and pumping action during the injection process. At the same time, in order to obtain a larger injection force, it is often driven by double servo motors. The transmission method of double screw rods, this structure is relatively large in size, and the cost of materials required is relatively high
