[0026] As an implementation method in this embodiment, Figure 1-Figure 5 As shown, a valve 231 is fixedly connected to the front of the hollow seat 23, a pressure relief valve 232 is fixedly connected to the front of the hollow seat 23, an air pump 233 is fixedly installed on the top of the base 21, and the output end of the air pump 233 is fixedly connected to the front of the hollow seat 23, a support seat 22 is fixedly installed on the top of the base 21, and the lower mold body 1 is fixedly installed on the top of the support seat 22.
