AI Technical Summary
Technical Problem
In existing plastic injection molding equipment, plastic residue is easily left in the lower mold cavity after injection molding, which makes cleaning difficult and affects the quality of subsequent injection molding.
Method used
A plastic injection molding device incorporating a cleaning component was designed. The upper mold is driven to descend and fit against the lower mold by a hydraulic cylinder, and plastic residue in the molding hole is cleaned by air pump and right-angle tube jet.
Benefits of technology
It enables convenient and efficient cleaning of plastic residue from the lower mold cavity, ensuring the stability of injection molding quality and production efficiency.

Abstract
This utility model provides a plastic injection molding device, relating to the field of plastic production technology. It includes a worktable, with a lower mold fixedly installed in the center of the upper surface of the worktable. The lower mold has several molding holes on its bottom surface. A bracket is fixedly installed on the upper surface of the worktable, and a hydraulic cylinder is fixedly installed on the upper surface of the bracket. The output end of the hydraulic cylinder passes through the bracket and is fixedly installed with an upper mold. In this utility model, after the plastic cools, the operator removes the molded part, thus completing the injection molding. After removing the molded part, the operator starts a motor, causing its output shaft to drive a lead screw to rotate. The rotating lead screw moves a slider and a bracket through a threaded connection. The operator then activates a guide rail, causing its moving end to move a right-angle tube. Subsequently, the operator starts an air pump, causing the right-angle tube to spray air and blow out plastic residue inside the molding holes for easy cleaning.
