[0028] Specifically, if Figure 1 and Figure 3 As shown, when it is necessary to eject the lower mold cavity 16 to take out the product inside the lower mold cavity 16, the drive motor 24 is started, and the drive motor 24 drives the turntable 19 to rotate through the rotating shaft 23, so that the movable block 22 can rotate inside the slide groove 20, and the movable plate 3 drives the push plate 15 to rise through the connecting rod 17. The rise of the push plate 15 can push the lower mold cavity 16 to eject the lower mold cavity 16 from the inside of the lower mold 2, thereby facilitating the removal of the product formed inside the lower mold cavity 16, and the limit rod 18 can limit the movable plate 3 to improve the stability of the lifting and lowering of the movable plate 3.

[0029] A low-temperature box 4 is provided on the left side inside the lower mold 2. An air pump 6 is installed on the top of the low-temperature box 4. The output end and input end of the air pump 6 are respectively fixedly connected to a pipe 14. An air blowing port 25 is provided at one end of the pipe 14 near the middle. The bottom end of the pipe 14 passes through the interior of the low-temperature box 4. The pipe 14 is provided outside the lower mold cavity 16.

The support block 12 can support the lower mold cavity 16 through the connecting block 11. The air pump 6 extracts the low-temperature gas inside the low-temperature box 4 into the interior of the pipeline 14 through the pipeline 14, and then blows the gas to the outer wall of the lower mold cavity 16 through the blowing port 25 to cool the interior of the lower mold cavity 16, so that the product inside the lower mold cavity 16 can be quickly molded, which can improve the efficiency of product molding. It is necessary to eject the lower mold cavity 16 to remove the lower mold.
