Two inner molds 25 are arranged on the inner walls of the two sets of outer molds 6. Through the mutual cooperation between the first cylinder 8 and the second cylinder 16, under the action of the connecting column 17, the top plate 5 rises, driving the pressing block 4, the mounting block 18 and the oblique rod 19 to move upward. Under the action of the sliding groove 21, the two outer molds 6 drive the inner molds 25 to move outward, so as to facilitate demolding. A plurality of second through grooves 22 are arranged at the middle position of the upper surface of the base 1. A first frame 23 and a second frame 24 are arranged at the middle position of the lower surface of the base 1 and are connected end to end. Through grooves 14 are provided on the upper surface, the lower surface and the front and rear end faces of the first frame 23.

By using the downward movement of the inclined rod 19, under the action of the chute 21, the two outer molds 6 drive the inner mold 25 to move inward, making the two outer molds 6 fit tightly. At the same time, the base 1 is in contact with the support table 2. Then, pouring is carried out from the pouring port 7. After pouring is completed, air is pumped into the through grooves 14 at the front and rear ends of the first frame 23 and the second frame 24, so that the gas jacks up the vibrating rod 27 to vibrate the cavity core 26 repeatedly, thus facilitating the separation between the cavity core 26 and the finished product. Then, by using the first cylinder 8 and the second cylinder 16, the top plate 5 moves upward, driving the pressing block 4, the mounting block 18 and the inclined rod 19 to move upward. By using the upward movement of the inclined rod 19, under the action of the chute 21, the two outer molds 6 drive the inner mold 25 to move outward, opening the mold, and then the finished product can be taken out.
