Injection molding method for environment-friendly plastic box

Abstract

The invention relates to an injection molding method for an environment-friendly plastic box. Plastic box machining and manufacturing equipment is used and comprises a workbench and a placing table rotatably arranged on the outer wall of the workbench, a feeding device is arranged at the top of the workbench, a cooling device is arranged above the placing table, a dismounting device is arranged above the placing table, and a cleaning device is arranged above the placing table. According to the injection molding method for the environment-friendly plastic box provided by the invention, through cooperation of a current-conducting plate, an air pump and a battery, when the battery makes contact with the current-conducting plate, the air pump is powered on, airflow generated in the air pump is jetted to a feed hopper through an air blowing pipe, and therefore waste remaining on the inner wall of a mold box after demolding can be automatically cleaned, the waste in the mold box is prevented from being accumulated, the production quality of the plastic box is influenced, the cleaning time is saved, the working efficiency is improved, and the manpower is saved.

Description

technical field [0001] The invention relates to the field of plastic box processing, in particular to an injection molding method for an environmentally friendly plastic box. Background technique [0002] Environmentally friendly plastic box means that all the indicators of the product meet or exceed the national quality standards, and it is hygienic, non-toxic, and non-polluting. Its appearance brings hope for reducing or eliminating white pollution. [0003] Plastics are based on synthetic or natural polymer resins. After adding various additives, it has ductility under certain temperature and pressure, and it is a kind of material that can fix its shape after cooling. Plastic boxes are made of PVC / PET / PP / PS and other related plastic products, such as transparent folding boxes, cylinders, sky and earth cover boxes, handle bags, elevator hanging pieces, etc., and can be UV offset printing, silk screen printing, bronzing / Silver, frosted and other printing effects, and eas...

AI Technical Summary

Problems solved by technology

[0006] 1. When injecting the mold, the injection liquid will be fed continuously, which will easily cause the injection liquid to overflow the outside of the mold, waste materials, and cause burrs on the surface of the plastic box after injection molding;

[0007] 2. When removing the plastic box after injection molding, some residual material may remain or adhere to the inner wall of the mold. After cleaning the inside with water, it is necessary to wipe or dry the inside of the mold. The steps are very cumbersome , time-consuming, reducing work efficiency
