Screw type injection molding device

Abstract

The invention discloses a screw type injection molding device. The device comprises an injection molding machine shell, wherein a feeding hopper is arranged at the upper end of the injection molding machine shell; an injection molding screw rod is arranged inside the injection molding machine shell, a screw rod edge is arranged at the upper end of the injection molding screw rod, the right end ofthe injection molding screw rod is connected to a driving motor, and the left end of the injection molding screw rod is connected to a screw rod head; and an injection molding nozzle is arranged at the left end of the injection molding machine shell, wedge grooves are formed in the inner wall of the injection molding machine shell, and ultrasonic cleaning structures are installed in the wedge grooves. According to the screw type injection molding device, the ultrasonic cleaning mechanisms are arranged on the injection molding machine shell, ultrasonic waves are radiated into the interior of the injection molding machine shell by utilizing the radiation surfaces on the ultrasonic cleaning mechanisms, the long injection screw rod is cleaned through the plurality of ultrasonic cleaning mechanisms, and under the action of the ultrasonic waves, the rotating injection molding screw rod utilizes the cavitation effect, the acceleration effect and the direct inflow effect of the ultrasonic waves in the liquid to perform direct action and indirect action on liquid and dirt, so that a dirt layer is dispersed, emulsified and stripped to achieve the cleaning purpose, and the device is worthy ofpopularization.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a screw type injection molding device. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. [0003] Precision injection molding, strictly speaking, refers to the dimensional accuracy of plastic products produced by injection molding machine equipment, which can reach below 0.01mm, usually an injection molding production method with a size between 0.01mm and 0.001mm. Precision inject...
