Description

Technical Field

[0001] The present application relates to the technical field of injection molded parts production and waste material treatment, and specifically to a material rod and injection molded product cavity separation device. Background Art

[0002] In the injection molding process, separating the molded product from the sprue (also known as the sprue handle or nozzle sprue) is a critical step. Injection molding processes are categorized into cold runner and hot runner processes, and corresponding injection molds are also categorized into cold runner and hot runner types. Cold runner molds are widely used in various injection molding applications due to their low cost, simple structure, and ease of maintenance. However, this process generates a large amount of sprue during production, which requires separation and collection from the molded product.

[0003] Currently, the separation of the sprue and the injection molded product mostly relies on manual operation. Manual separation is inefficient and costly, and there is a risk of quality problems and safety accidents caused by improper operation of workers. Utility Model Content

[0019] Furthermore, the inner wall of one end of the connecting frame is slidably arranged on the outer surface of the middle part of the second limiting rod, and one end of the second limiting rod is arranged on the bottom of the product grabbing fixture through a fixing plate.
