[0002] The blister forming machine is also called a thermoplastic forming machine. The process of this forming equipment is mainly to use the vacuum suction force generated by a vacuum pump to heat and soften various thermoplastic plastic sheets through a mold to form vacuum covers of various shapes, or attach them to the surface of products of various shapes. Blistering is divided into thin sheet blistering and thick sheet blistering according to the thickness of the sheet. After searching the patent with publication number CN216993032U, a thick sheet blister forming machine automatically and synchronously cooperates with the mold locking device. The utility model cooperates with the card slot through the oblique square block, so that the lower mold is in a locked state to avoid shaking of the lower mold or causing the gap between the lower mold and the upper mold to be too large, affecting the effect of blister forming. However, this thick sheet blister forming machine automatically and synchronously cooperates with the mold locking device, and no cooling device is set, resulting in unsatisfactory cooling effect, slow shaping speed, and affecting work efficiency.
