[0011] Preferably, limiting grooves are provided on the inner walls on both sides of the bracket, limiting blocks are slidably connected inside the limiting grooves, and the ends of the limiting blocks are fixedly connected to the side walls of the movable plate.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] 1. When the lower mold needs to be installed inside the base, the lower mold is placed inside the slot, and the rod slides into the lower mold and contacts the lower end of the rotary block. Then, the rotary block is rotated forward to connect with the rod body through threads, so that the lower mold can be installed quickly and conveniently.
