Preferably, there are ten upper exhaust passages in total, and the ten upper exhaust passages are evenly arranged outside the two upper mold cavities.

Preferably, the upper exhaust channel is an L-shaped structure.

Compared with the prior art, the beneficial effects of the utility model are: the structure of the utility model is scientific and reasonable, and it is safe and convenient to use; exhaust grooves are uniformly arranged around the cavity on the silicone mold, and the exhaust groove is designed as an L shape, and the exhaust The air hole and the exhaust groove are in a right angle shape, which can effectively improve the efficiency of exhaust, and can effectively avoid the overflow of raw materials, avoid the occurrence of trapped air and the lack of glue, and reduce the defective rate, and there are two mold grooves inside the mold. Two molds can be molded at the same time, which effectively improves the production efficiency. The upper and lower molds are sealed and fixed by ten fixing columns and fixing holes, which improves the sealing performance of the mold.
