Lateral glue injection device of injection molding machine

Abstract

The invention relates to the technical field of injection molding machine glue injection, and discloses a lateral glue injection device of an injection molding machine which comprises a base, a first fixing seat and a second fixing seat are arranged on the base, a positioning rod is connected between the first fixing seat and the second fixing seat, a movable support is arranged on the positioning rod in a sleeving mode, and a transmission mechanism is arranged on the movable support. A driving part drives the driving belt wheel to rotate, the driving belt wheel and the driven belt wheel are in transmission through a belt, namely, the driven belt wheel is driven to rotate, the injection screw rod rotates at a high speed, glue injection and injection operation of materials in the material storage barrel is completed, the driving part is designed in a side mode, the length of the device can be effectively reduced, and occupied space is reduced. Whole machine equipment is more attractive, driving belt wheels of different sizes can be replaced according to requirements, namely the speed ratio is changed by changing the size of the belt wheel of the power output part, the problem that the speed ratio is inconvenient to change in the center of the screw rod is solved, and the scheme is novel in structure, easy and convenient to operate and wide in application range and meets use requirements.

Description

technical field [0001] The invention relates to the technical field of glue injection for injection molding machines, in particular to a side-mounted glue injection device for injection molding machines. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The injection molding function The plastic is heated and high pressure is applied to the molten plastic, causing it to shoot out and fill the mold cavity. [0003] The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms: plunger type, screw type, and screw pre-molded plunger injection type. At present, the most widely used is the screw type. In one cycle of the machine, ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a side-mounted injection molding machine injection device to solve the disadvantages of the prior art that the single cylinder injection device is mostly placed at the tail of the propulsion cylinder. The problem is that it directly drives the piston rod of the propulsion cylinder to rotate, and transmits the rotational force to the injection screw, which causes considerable wear and tear on the seal of the piston rod of the propulsion cylinder due to rotation, greatly shortening the service life of each component
