[0025] The upper surface of the lower mold half 2 is provided with a bowl-shaped die groove 202, and the bowl-shaped punch 102 can be inserted into the bowl-shaped die groove 202, and a distance is provided between the bowl-shaped punch 102 and the bowl-shaped die groove 202;

[0026] Among them, cooling components 3 are provided in both the upper mold 1 and the lower mold 2. The cooling component 3 in the upper mold 1 encloses the bowl-shaped punch 102, and the cooling component 3 in the lower mold 2 surrounds the bowl-shaped die groove 202. A feed port 101 is protrudingly fixedly installed on the upper surface of the upper mold 1, and a discharge port 104 is provided in the feed port 101. The discharge port 104 is opposite to the guide groove 203 provided on the upper surface of the upper mold 1, and the guide groove 203 is connected to the four groups of bowl-shaped die grooves 202.

[0027] According to the above design, through the design of the upper mold 1, the lower mold 2, the electric push rod 201, the bowl-shaped convex mold 102, the bowl-shaped concave mold groove 202 and the cooling component 3, during injection molding, the upper mold 1 can be driven to move vertically downward by starting the electric push rod 201, and the bowl-shaped convex mold 102 on the lower surface of the upper mold 1 is inserted into the bowl-shaped concave mold groove 202 opened on the upper surface of the lower mold 2, and after the upper mold 1 and the lower mold 2 are completely fitted, a distance is formed between the bowl-shaped convex mold 102 and the bowl-shaped concave mold groove 202, and then the molten plastic can be poured from the feed port 101, and the molten plastic will flow into the discharge port 104 along the feed port 101, so that the molten plastic flows into the guide groove 203 along the discharge port 104, and flows into the bowl-shaped concave mold groove 202 along the guide groove 203, and with the blocking of the bowl-shaped convex mold 102, the molten plastic can be cooled and hardened to form a bowl shape;

[0028] In the process of the material flowing into the bowl-shaped die groove 202 for cooling, the coolant in the cooling component 3 will circulate on the outer surface of the bowl-shaped punch 102 and the periphery of the bowl-shaped die groove 202, and each time the cooling component 3 circulates, the heated coolant will flow into the upper half mold 1 and the lower half mold 2 again for cooling.

The mold temperature can be quickly and evenly reduced, which can ensure that all parts of the plastic part are evenly cooled, reduce shrinkage deformation, internal stress and warping caused by uneven cooling, and thus improve the dimensional stability and appearance quality of the final product.

[0029] The rapid cooling efficiency can accelerate the cooling process of molten plastic, thereby shortening the entire production cycle and enabling more products to be produced in the same time. By quickly and evenly lowering the mold temperature, it can ensure that all parts of the plastic parts are cooled evenly, reducing shrinkage deformation, internal stress and warping caused by uneven cooling, thereby improving the dimensional stability and appearance quality of the final product.

[0030] Specifically, Figure 4-5 As shown, the cooling assembly 3 includes a square cylinder 302, which is fixedly installed at one end of the lower half mold 2. A heat sink is fixedly installed in the square cylinder 302, and a liquid inlet pipe 304 and a liquid outlet pipe 305 are inserted in the heat sink of the square cylinder 302. The liquid inlet pipe 304 is connected to the water outlet of the water pump 303, and the liquid outlet pipe 305 is connected to the water inlet of the water pump 303.

[0031] Specifically, the liquid inlet pipe 304 and the liquid outlet pipe 305 in the square tube 302 are in a curved shape, and a heat dissipation fan 301 is fixedly installed on the upper surface of the square tube 302 .

[0032] Specifically, a water-passing ring 307 is fixedly installed in the plug-in groove 103 , the water-passing ring 307 is connected to the liquid inlet pipe 304 , and the water-passing ring 307 is sleeved on the outer surface of the bowl-shaped punch 102 .

[0033] Specifically, a cooling pipe 306 is inserted into the lower half mold 2 , and the cooling pipe 306 is connected to the liquid outlet pipe 305 .

[0034] Specifically, the liquid inlet pipe 304 and the liquid outlet pipe 305 extending from the upper half mold 1 and the lower half mold 2 are connected, and the other ends are connected to the water outlet and the water inlet of the water pump 303 respectively.

[0035] According to the above design, through the design of the water pump 303, the liquid inlet pipe 304, the liquid outlet pipe 305, the cooling pipe 306 and the water ring 307, when the material flows into the bowl-shaped die groove 202 for cooling, the cooling liquid in the liquid outlet pipe 305 can be supplied into the cooling pipe 306 by starting the water pump 303, and the cooling pipe 306 is around the bowl-shaped die groove 202, so that the molten plastic therein can be cooled through the bowl-shaped die groove 202, and the cooling liquid passing through the cooling pipe 306 will flow into the liquid inlet pipe 304 again, so that the liquid inlet pipe 304 supplies the cooling liquid into the water ring 307, and the water ring 307 is mounted on the outer surface of the bowl-shaped punch 102, so that By lowering the temperature of the bowl-shaped punch 102, the lower temperature can be transmitted to the molten plastic through the bowl-shaped punch 102 to accelerate the cooling efficiency. When the coolant flows out from the water ring 307, the coolant will enter the heat sink of the square tube 302 through the liquid inlet pipe 304 to dissipate the heat of the coolant in the pipe. The heat in the heated heat sink will be driven by the cooling fan 301, so that the cooled coolant will enter the water pump 303 again, and then be supplied to the liquid inlet and outlet pipe 305 by the water pump 303 again, and flow into the cooling pipe 306 for another cooling cycle. After multiple cycles, the cooling efficiency of the mold can be accelerated, and the cooling process is fast and balanced.
