[0042] In order to facilitate the mold to be kept cool during plastic injection molding and improve the injection molding effect, thereby further improving the service life of the plastic injection mold, when in use, first drive the electric push rod 20 so that the four sliding seats 18 on the auxiliary mold 15 located on the movable end of the electric push rod 20 are limited by the four sliding rods 12 to slide downward, and the auxiliary mold 15 is buckled on the main mold 9, and the synchronous injection port I 10 and the injection port II 16 are buckled with each other to form an injection port that is convenient for the injection molding equipment to perform injection molding, and then the injection molding work is performed in the auxiliary mold 15 and the main mold 9. In order to prevent the temperature of the auxiliary mold 15 and the main mold 9 from being too high during injection molding, the two water pumps 22 are driven to circulate the coolant in the corresponding liquid storage tank 25 on the lower side through the two reciprocating cooling pipes 21, and the cooling liquid is circulated in the cooling pipe 21 through the left side of the cooling pipe 21. The cooling liquid is pumped into the cooling tube 21, and the cooling liquid flows back into the liquid storage tank 25 through the right port of the cooling tube 21, so that a circulation is formed in the cooling tube 21, and each cooling tube 21 is a metal pipe with a smooth surface, which is convenient for rapid temperature transfer, so that when the auxiliary mold 15 located on the upper side slides on the cooling tube 21 by relying on the side holes II 17 on the front and rear sides thereof, the auxiliary mold 15 is cooled by the cooling liquid flowing in each cooling tube 21, and the main mold 9 is cooled by relying on the side holes I 11 on the main mold 9 located on the lower side thereof by relying on the cooling liquid flowing in each cooling tube 21, so that the low temperature of the injection mold can be maintained during the injection molding work, and the staff is prevented from being scalded when touching the mold, and it is further convenient to improve the time efficiency of subsequent cooling and cooling of the plastic tools for injection molding;

[0045] In order to facilitate the rapid cooling of the plastic tooling formed in the main mold 9, when in use, when the electric push rod 20 is driven to move the sub-mold 15 in the opposite direction and there is a formed plastic tool in the main mold 9, the driving motor 8 causes the screw 3 to rotate, and then the transverse displacement seat 26 on the screw 3 moves laterally. At this time, the fan box 31 is driven synchronously. The fan box 31 is a product available in the prior art and is not described in detail. The air outlet of the fan box 31 faces downward. When the fan box 31 moves laterally, it passes over the plastic tooling formed in the main mold 9, thereby quickly and comprehensively performing adaptive cooling on the formed mold.
