[0002] Plastic products are various products made from synthetic or natural polymer compounds (plastics) as the main raw material through processes such as injection molding, blow molding, extrusion, and calendering. During the processing and molding of plastic products, drilling equipment is typically used to punch holes in them.

[0003] CN220128988U discloses a multi-point punching device for molding plastic products, including a punching table. Two telescopic rods are fixedly connected to the top of the punching table. A first adjusting frame is fixedly connected to the top of one of the telescopic rods. A moving groove is formed on one side of the first adjusting frame. A fixed plate is fixedly connected to the side of the first adjusting frame away from the moving groove. An adjusting mechanism is fixedly connected to the back of the fixed plate. A second adjusting frame is fixedly connected to the top of the other telescopic rod. An adjusting groove is formed on one side of the second adjusting frame.

The moving component 4 can drive punch 5 to move, thereby realizing multi-point punching.
