The bottom mold 1 and the upper mold 3 are slidably matched through the guide post 4. The bottom surface of the upper mold 3 corresponds to the upper surface of the molded product. The upper mold 3 is provided with a feed hole communicating with its bottom surface. The bottom mold 1 is provided with a first telescopic member for pushing the mold forming plate 2 to move. The mold forming plate 2 is movably matched with the bottom mold 1. The upper surface of the mold forming plate 2 corresponds to the bottom surface of the molded product. An empty cavity 103 is provided between the bottom mold 1 and the mold forming plate 2. The bottom mold 1 is provided with an air inlet communicating groove 102 connected to the empty cavity 103. When forming the product, the upper mold 3 can slide along the guide post 4, so that the bottom surface of the upper mold 3 corresponds to the upper surface of the mold forming plate 2. A cavity for assisting in product forming is formed between the bottom surface of the upper mold 3 and the upper surface of the mold forming plate 2. The product material is guided into the cavity through the feed hole. After the product is cooled and solidified, the upper mold 3 is pushed upward by the first telescopic member to realize the separation of the upper mold 3 and the mold forming plate 2.
