Description

Technical Field

[0001] The utility model relates to the technical field of plastic boxes, in particular to an injection molding demoulding device for a plastic box. Background Art

[0002] Plastic boxes are a common packaging container, usually made of plastic. Compared with boxes made of other materials, plastic boxes are lighter and easier to handle and transport. They are usually made by injection molding, which is a common production process used to manufacture plastic boxes of various shapes and sizes. This process heats and melts plastic particles, injects them into a mold, and finally obtains a molded plastic box after cooling and solidification.

[0003] Existing plastic box injection molding devices are usually composed of an injection molding machine, a mold, a feeding mechanism, etc. After the injection molding machine heats and melts the plastic particles, the plastic is injected into the mold through the feeding mechanism. After cooling and solidification, a molded plastic box is finally obtained. The design and manufacture of the mold have an important impact on the quality and production efficiency of the plastic box. The function of the feeding mechanism is to accurately deliver the plastic to the injection molding machine to ensure the smooth progress of the injection molding process. When using the existing plastic box injection molding device, it is necessary to pay attention to the maintenance and care of the equipment to ensure its normal operation and service life.

[0004] However, the existing plastic box injection molding device cannot eject it quickly and conveniently after the injection molding is completed, which will extend the production cycle and reduce production efficiency. It takes more time and effort to remove the plastic box, which increases labor intensity. In addition, forced removal may cause the plastic box to deform or be damaged, affecting product quality. Therefore, a plastic box injection molding demolding device is proposed to solve the above problems. Utility Model Content
