[0002] The commonly used mold cooling method in the prior art is to add water channels in the injection mold cavity and core, and then use external constant temperature water to take away the heat to cool the mold, and add steel inserts with fast heat dissipation in the local overheated area to allow the local inserts of the mold to quickly dissipate heat, but the insert area still cannot achieve rapid cooling. Summary of the invention

[0003] The problem to be solved by the utility model is to provide a plastic mold structure with a reduced cooling cycle, thereby overcoming the deficiencies in the prior art.

[0005] The above structure uses a cooling air converter to convert the provided compressed air into cold air through the principle of vortex theory and spray it into the cavity, thereby quickly cooling the area in the cavity.

[0006] Optionally, a compressed air adapter block is provided on the air pipeline between the air circuit switch and the air nozzle.

[0007] Optionally, the bottom surface of the gas circuit switch has a switch protrusion, which extends downward below the bottom surface of the cavity. When the cavity and the core are closed, the switch protrusion will be lifted up by the top surface of the core. In this way, the cooling system can be automatically opened and closed with the mold closing and opening without manual or computer control.

[0008] Optionally, the gas circuit switch is fixed to the outer wall of the cavity through an adjustment block, the gas circuit switch is fixed to the adjustment block, the adjustment block has a longitudinal long hole, the longitudinal long hole has an adjustment bolt, and the adjustment bolt is connected to the threaded hole set on the outer wall of the cavity. The installation form of the adjustment block is convenient for adjusting the position of the gas circuit switch, so that the replacement of the gas circuit switch can realize the function of automatic opening and closing.

[0009] Optionally, a pressing plate for fixing the air pipeline is provided on the outer wall of the cavity, and the arrangement of the pressing plate makes the air pipeline fit more closely to the outer wall of the cavity.

[0010] The utility model has the advantages and positive effects that when the mold structure is installed on a plastic mold of industrial equipment, the goal of rapid cooling can be achieved, so that the local overheated area can be cooled instantly, thereby improving the cooling cycle.
