The driving mechanism drives the movable mold plate and the fixed mold plate to close the mold to form a mold cavity, and the preform is manufactured by injecting the melt into the mold cavity to form the preform. Since the preform usually has textures, when taking out the formed preform, it is necessary not only to separate the separation plate and the cavity plate, but also to open the open mold cavity so that the robot can take away the preform.
