Specifically, the outer side wall and the inner side wall of the threaded ring 11 are provided with threads, that is, the threaded ring 11 is in threaded connection with the inside of the mounting seat 1, so that when the threaded ring 11 rotates along the circumferential direction, the threaded ring 11 can move along the axial direction until the clamped material body can be pushed out, and the material body falls off; subsequently, the screw thread ring 11 is reset and moved after pushing out the material body, so that the other reassembled material body can be pushed out; this is repeated, thereby improving the demolding efficiency.

According to the figure 1, a guide part 2 is arranged on a mounting seat 1 in a penetrating way; specifically, one end of the guide portion 2 is inserted from the bottom of the mount 1 and is inserted from the top of the mount 1. A plurality of teeth 21 are provided along the length of the guide 2, so that when the guide 2 is moved, the plurality of teeth 21 are used to push the gear assembly 3 into rotation, so that the threaded ring 11 can move axially when rotated, pushing the body out.

According to fig. 1-2, in particular, the gear assembly 3 comprises a driving gear 31 and a driven gear 32 fixedly sleeved on the threaded ring 11, wherein the tooth edge of the driving gear 31 is in meshed connection with the tooth edge of the driven gear 32, and the tooth edge of the driven gear 32 is also in meshed connection with the tooth part 21 on the guide part 2.
