[0002] An injection molding machine, also known as an injection molding machine or simply an injection molding machine, is a type of equipment used for plastic processing. It is mainly used to produce various thermoplastic products and some thermosetting plastic products. Injection molding machines are widely used in many industries such as automotive, electronics, medical, and packaging.

[0003] Injection molding machines contain numerous protective components, among which nylon safety guards are a common choice. Due to its high strength and impact resistance, nylon is frequently used to manufacture machine guards or shells, protecting internal components from external environmental influences and providing a degree of safety isolation for operators. In injection molding machines, nylon is primarily used to make safety doors. However, existing nylon safety doors require manual opening and closing. To increase processing speed, workers often keep the safety doors constantly open, posing a safety hazard. Furthermore, during processing, the safety doors are prone to slippage and fail to self-lock, reducing the safety of production processes. Utility Model Content
