[0028] Further, the compression mold mechanism comprises a top support plate 10, a heating pipe 11, a heating motor 12, a compression mold plate 18, a compression mold base 19, a guide pipe 20, and a transmission shaft two 21. The compression mold base 19 is fixedly installed on the plane of the supporting bottom plate 1 corresponding to the rear of the base 15.
