Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, and more specifically, to an injection molding device for producing plastic products. Background Art

[0002] In the existing technology, during the injection molding process, the feed pipe is a key component for transporting plastic raw materials to the injection molding machine. However, since the plastic raw materials may accumulate or condense in the feed pipe, especially when the raw materials have poor fluidity or low temperature, the feed pipe may be blocked, which will not only affect the continuity of the injection molding process, but also may lead to waste of raw materials and reduced production efficiency.

[0003] During the molding process, the injection molding device usually needs to use a positioning rod to accurately control the position of the movable mold and the fixed mold. During long-term use, if the positioning rod lacks proper lubrication, it may cause increased friction, increased wear, and even cause equipment failure.

[0004] After injection molding, the molded plastic products need to be removed from the mold and subjected to subsequent processing, such as cooling, trimming or packaging. If the equipment lacks an effective post-discharge parts collection assembly, it may lead to low production efficiency, increased labor costs, and even product damage. Utility Model Content
