As a technical optimization scheme of the utility model, the air blowing component comprises a miniature fan 7 and a plurality of air guide pipes 8, wherein the fan 7 is arranged in the air guide pipe 5, the plurality of air guide pipes 8 are arranged in the water storage cylinder 6, and two ends of the air guide pipes 8 extend to the outside of two ends of the water storage cylinder 6; the setting of the air blowing assembly enables the push plate 1 to be cooled in the process of air flow, so that the cooling speed of the formed part is improved, and the formed part is conveniently demoulded.
As a technical optimization scheme of the utility model, the air duct 8 is in a spiral state, and the air duct 8 has heat conductivity; the air duct 8 is spiral, so that the cooling capacity of the liquid in the water storage cylinder 6 can cool the air in the air duct 8 better.
As a technical optimization scheme of the utility model, the upper end and the lower end of the outer ring surface of the water storage cylinder 6 are respectively provided with a water inlet valve 9 and a water outlet valve 10, and the end parts of the water inlet valve 9 and the water outlet valve 10 are respectively provided with a dust cap; the water inlet valve 9 and the water outlet valve 10 are arranged, so that the replacement of the liquid in the water storage barrel 6 is facilitated.
As a technical optimization scheme of the utility model, an air inlet pipe 3 is respectively connected with push rods 2 at the ends of two push plates 1, and an air outlet pipe 4 is arranged at the end part of the push rod 2 at the other end of the two push plates 1; because the air inlet pipe 3 and the air outlet pipe 4 are positioned at the two ends of the two pushing plates 1, air enters one end of the inside of the pushing plates 1 from the air inlet pipe 3 and flows out through the other end of the pushing plates 1, namely, the air flows in the pushing plates 1 to cool the pushing plates 1, so that the cooling speed of the formed part is improved.
As a technical optimization scheme of the utility model, a plurality of rod bodies of the push rods 2 are jointly fixed with a stabilizing frame 11, and a reset spring 12 is sleeved on the rod body of the push rod 2 between the stabilizing frame 11 and an external mold; the reset spring 12 is beneficial to improving the stability of the push plate 1.
