Injection molding direct-drive glue injection structure

Abstract

The invention discloses an injection molding direct-drive glue injection structure, and relates to the technical field of glue injection mechanisms for injection molding machines. A glue injection power assembly drives a glue melting power assembly to work. The glue injection power assembly outputs torque. A ball screw, a sensor and the glue melting power assembly drive a screw to move front and back to achieve injection and loosening actions, and the glue melting power assembly can drive the screw to rotate to achieve a glue melting action. An injection moving support is connected with an injection table body. The whole device is driven by an injection moving oil cylinder assembly to move back and forth on an injection moving linear guide rail, so that a power transmission link is reduced. The injection molding direct-drive glue injection structure has the advantages of being compact, easy and convenient to install and maintain, good in overall rigidity effect, low in operation noise, economical, high in autonomous controllable capacity and the like.

Description

technical field [0001] The invention relates to the technical field of an injection mechanism for an injection molding machine, in particular to a direct-drive injection structure for injection molding. Background technique [0002] At present, electric injection units for general injection molding machines mostly use servo motors, synchronous wheels, and synchronous belts to provide power and drive ball screw transmission to complete the injection action. The glue melting action also uses a servo motor, and completes the power transmission through the synchronous wheel and the synchronous belt. [0003] This kind of structure is complex, and the servo motor adopts a general model, which is poorly matched with the injection mechanism, resulting in larger dimensions and poor economy. At the same time, there are disadvantages such as high rotation noise of the synchronous belt, complicated installation process of the synchronous wheel, and fatigue and aging of the synchronous...

AI Technical Summary

Problems solved by technology

[0003] This kind of structure is complicated, and the servo motor adopts a general model, which is poorly matched with the injection mechanism, resulting in larger dimensions and poor economy.

At the same time, there are disadvantages such as large rotation noise of the synchronous belt, complicated installation process of the synchronous wheel, fatigue and aging of the synchronous belt, etc.

And the current high-performance synchronous belts are basically foreign brands, and the localization rate is low

The injection screw of the universal electric injection platform adopts the installation and fixing method of angular contact ball bearings. This kind of bearing basically relies on imports, which is expensive and has a complicated structure.
