Description

Cooling device for bottle cap injection molding Technical Field The utility model relates to the technical field of mold design, in particular to a cooling device for bottle cap injection molding. Background The traditional bottle cap mold cooling water system adopts a water-proof sheet to divide cooling water holes, so that cooling water reaches the top of a mold core, the cooling water holes need to keep a safe distance of 13mm from the top of the mold core during processing, and the mold core is prevented from cracking due to over-deep processing. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a cooling device for injection molding of a bottle cap, which solves the problems that the bottle cap cannot be cooled rapidly in production due to the fact that the distance between the cooling water hole and the top of the mold core is long and the cooling water cannot completely cover the top of the mold core, and the bottle cap is easy to lift up, burst up deformation and the like. In order to solve the problems, the technical scheme adopted by the utility model is as follows: The utility model provides a cooling device for bottle cap injection molding, which comprises a fixed die, wherein a pouring gate is arranged in the middle of the upper end of the inner part of the fixed die, a push rod with a hollow inner part and an opening at the upper end and the lower end is arranged at the lower end of the fixed die, an insert is connected to the upper end of the inner part of the push rod, a hole is arranged in the insert, a water-proof sheet is connected to the middle of the inner part of the push rod, the upper end of the water-proof sheet is connected to the middle of the inner part of the insert, an opening at the lower end of the push rod is connected with an opening at the left side and the right side, a water-proof sheet in the opening is also connected to the inside of the opening, the water-proof sheet in the opening is fixedly connected with the water-proof sheet in the push rod, a movable template is sleeved outside the upper end of the push rod, the outside of the movable template is connected with an outside movable template, the outside of the movable template is tightly attached to the inner side of the movable template, and the upper end of the outside movable template is tightly attached to the opening at the lower end of the inner part of the fixed die.
