DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Reference Figures 1 to 3 A die-casting mold includes a die-casting table 1, characterized in that: a mold 2 is arranged on the top of the die-casting table 1, a pressure block 3 is arranged above the die-casting table 1, and the pressure block 3 can be stuck in the mold 2, a first hydraulic press 31 is arranged above the pressure block 3, and the telescopic end of the first hydraulic press 31 is connected to the top of the pressure block 3, a heat dissipation chamber 12 is arranged inside the die-casting table 1, and the four sides of the heat dissipation chamber 12 are respectively provided with air flow ports 11 connected to the outside world, and fans are installed on two non-adjacent air flow ports 11, and a plurality of heat-conducting columns 23 are slidably arranged at the bottom of the mold 2, and the bottom of the heat-conducting column 23 penetrates the mold 2 and extends into the heat dissipation chamber 12, and is connected to a heat dissipation column 231, and a push plate 4 is slidably arranged at the bottom of the heat dissipation chamber 12.

[0015] The mold 2 is fixedly mounted on the die casting table 1 by bolts. The mold 2 is composed of a heat insulating layer 21 and a heat conducting layer 22. The side in contact with the die casting table 1 is the heat insulating layer 21 made of a heat insulating material, and the side in contact with the molten metal is the heat conducting layer 22 made of a heat conducting material. A circle of rubber pads is arranged around the bottom of the mold. The outer surface of the heat dissipation column 231 is provided with a plurality of metal sheets, and the top of the heat dissipation column 231 is connected to the heat conducting column 23. At the bottom of the push plate 4, a second hydraulic press 41 is arranged in the die casting table 1, and the telescopic end of the second hydraulic press 41 is connected to the bottom of the push plate 4.

[0016] When the device is in use, the molten metal is poured into the mold 2. The first hydraulic press 31 is controlled to drive the pressing block 3 downward into the mold 2 for die casting. The heat in the mold 2 is transferred to the heat-conducting column 23 through the heat-conducting layer 22, and then transferred from the heat-conducting column 23 to the heat-dissipating column 231. The fan on the airflow port 11 is started, and the airflow generated by the fan generates convection in the heat-dissipating chamber 12 and flows out from the other two airflow ports 11. In this process, the airflow takes away the heat on the heat-dissipating column, accelerating the cooling of the mold and the metal parts in the mold. After completion, the pressing block is lifted, and then the second hydraulic press is controlled to drive the push plate to move upward. During the movement of the push plate, the heat-dissipating column and the heat-conducting column are pushed upward, and the metal parts in the mold are lifted up, making it convenient for the staff to take them out.
