[0029] The air cylinder 222 operates, the air cylinder 222 pushes the fixed plate 223 to move, the fixed plate 223 drives the push rod 224 to move, so that the polyurethane ejector block 225 contacts the part and pushes the part, and the part is pushed out above the lower die 1, thereby realizing automatic material taking, improving work efficiency, and reducing the complexity and danger of manual operation.

[0030] In this embodiment, the pushing unit 22 further includes two limiting seats 227 fixedly installed inside the base plate 221. A limiting rod 228 is slidably installed through the inside of the limiting seat 227, and one end of the limiting rod 228 is fixedly connected to the fixed plate 223.

[0031] During the movement of the fixed plate 223, the fixed plate 223 drives the limiting rod 228 to slide inside the limiting seat 227, thereby realizing the limitation of the movement of the fixed plate 223.

[0032] In this embodiment, a protective cover 2210 is fixedly installed above the base plate 221, and a baffle 226 is fixedly installed in the middle of the side of the fixed plate 223 where the push rod 224 is installed.
