A mold I and a mold II are symmetrically arranged up and down, have the same structure and respectively comprise a mold body and a demolding mechanism, a plastic uptake cavity is formed on the sides, close to each other, of the two mold bodies, the demolding mechanisms are located at the four corners of the plastic uptake cavity, and each demolding mechanism comprises a demolding push rod and an elastic piece. The structure of the demolding push rod is the same as the shape of the hook, one end of the demolding push rod extends into the blister cavity, the other end of the demolding push rod extends out of the sides, close to each other, of the two mold bodies, the mold bodies are provided with telescopic cavities corresponding to the demolding push rod, the demolding push rod is arranged in the telescopic cavities in an up-down sliding mode, and elastic pieces are arranged in the telescopic cavities to drive the demolding push rod to reset. In the press fit process of the first mold and the second mold, the
