Unlike floating bottles and floating cylinders, the float ball does not have an opening and is in a sealed state when it is manufactured. It does not need to be additionally sealed or have a cover. Conventional float balls are blow molded using a blow molding mold. Due to the shape of the float ball, multiple groove structures need to be provided on the surface of the float ball to facilitate subsequent handling and use. In the production of existing float ball blow molding molds, if the side groove structure of the float ball needs to be formed simultaneously, a fixed forming part is designed in the mold. Due to the limitation of the groove structure, demolding is easily affected after forming, interference occurs, and it is very troublesome. Therefore, there is an urgent need to design a float ball blow molding mold lever quick opening and closing mold driving mechanism that can overcome the above defects.
