Description

Technical Field

[0001] The utility model relates to the technical field of demoulding mechanisms, in particular to a secondary demoulding mechanism for side hooks. Background Technique

[0002] Injection molding is a method for manufacturing industrial product shapes. Products usually use rubber injection molding and plastic injection molding. The injection molding process is realized through an injection molding machine and a mold. When there are structures such as hooks in the product, the mold often needs to cooperate with a demoulding mechanism during use.

[0003] In the prior art, the traditional hook demoulding mechanism is generally driven by a switch. After reaching the stroke, it will rebound, resulting in different opening values of the hook amount, affecting the forming quality of the hook, and not being suitable for multi-batch processing. It is easy for the injection-molded products to adhere to the switch and other components, affecting the service life. Therefore, it is necessary to improve a secondary demoulding mechanism for side hooks to solve the above problems. Content of the Utility Model
