A flame head 15 is provided inside the bracket 1 to preheat the die-casting part of the mold. There are two flame heads 15 and they are located inside the bracket 1. The flame heads 15 are connected to the gas to enable continuous preheating. The output ends of the two flame heads 15 are respectively facing the protruding part of the movable mold 3 and the concave part of the static mold 8, and preheat the movable mold 3 and the static mold 8 respectively.

[0023] The base 7 supports the entire device. The base 7 is fixedly connected to the lower surface of the bracket 1 to provide a support point for the bracket 1. A heat insulation board 14 is provided between the base 7 and the bracket 1 to isolate heat and prevent damage to the base 7. The upper surface of the base 7 is fixedly connected to a static mold 8, which cooperates with the dynamic mold 3 for die casting. The upper surface of the static mold 8 is provided with a groove 9, which is engaged with the convex frame 4 so that the dynamic mold 3 and the static mold 8 are attached. The side surface of the static mold 8 is provided with a water inlet pipe 10 and a water outlet pipe 11. The water inlet pipe 10 is used to inject coolant into the mold, and the water outlet pipe 11 is used to discharge overheated coolant. The water inlet pipe 10 is connected to the first cooling channel 12 to cool the static mold 8. The water outlet pipe 11 is used to discharge overheated coolant. The water inlet pipe 10 is connected to the first cooling channel 12 to cool the static mold 8. 1 and the first cooling channel 12 are connected with the second cooling channel 6 during operation to form a water circulation system, which cools the dynamic mold 3 and the static mold 8 at the same time.

[0024] Working principle: When using the device, start the flame head 15 to preheat the lower surface of the movable mold 3 and the upper surface of the static mold 8. After preheating, start the telescopic rod 2 to extend the movable mold 3 toward the static mold 8, so that the convex frame 4 is fitted with the groove 9, and the protective door 17 is slid away to guide the molten metal into the filling port 5, so that the molten metal enters between the movable mold 3 and the static mold 8. After the injection is completed, slide the protective door 17, close the protective cover 16, and inject water into the water inlet pipe 10 to allow the coolant to enter the first cooling channel 12. Through the connection between the first cooling channel 12 and the second cooling channel 6, the coolant enters the second cooling channel 6, so that the coolant cools the mold and the metal liquid inside the mold, and the metal heated by the cooling is cooled. The coolant is discharged from the water outlet pipe 11, and the mold is continuously cooled sufficiently. When the metal liquid solidifies, the water outlet pipe 11 is closed, the telescopic rod 2 is retracted, and the movable mold 3 is partially raised. The coolant inside the second cooling channel 6 is blocked by the convex frame 4 and flows around the casting. The warm coolant performs preliminary contact cooling on the casting. The water outlet pipe 11 is opened, and water is continued to be fed in through the water inlet pipe 10 to achieve stepped cooling of the casting, preventing the casting from being affected by excessive temperature changes and affecting its quality. After cooling is completed, the water is discharged through the water outlet pipe 11, the movable mold 3 is completely raised, and the protective door 17 is slid away. The staff can directly take out the casting without cooling the casting and the mold surface, and can proceed to the next step.
