During the curing process, the breathing membrane will adhere to the inner wall of the mold and is difficult to remove. When removing the breathing membrane, a certain amount of force may be required, which may cause damage or rupture of the breathing membrane. If the breathing membrane is damaged or deformed during the demolding process, the quality and performance of the breathing membrane may be affected, which may cause some breathing membranes to fail to meet the specified standards and need to be discarded or re-prepared, increasing costs and waste. In response to the above problems, a high-toughness breathing membrane preparation mold is proposed to solve them. Utility Model Content
