Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an automatic ejection injection mold. Background Art

[0002] An injection mold is a tool used to manufacture plastic products. It usually consists of two parts: a movable mold and a fixed mold. During the injection molding process, molten plastic is injected into the mold cavity and then cooled and solidified to form the desired product.

[0003] Automatic ejection of injection molds is designed to improve production efficiency and reduce manual labor. During the injection molding process, molten plastic is injected into the mold cavity, where it cools and solidifies to form the desired product. An automatic ejector automatically ejects the product from the mold after solidification, reducing manual operation time and labor while also improving production efficiency. However, current ejector mechanisms can only automatically discharge the molded part due to the gravity of the molded part when the side of the mold is opened. Injection molds with movable and static molds positioned above and below each other still require manual control after ejection, making the operation cumbersome and inconvenient.
