[0002] Die casting is a method of casting liquid die forging, a process completed on a dedicated die casting die forging machine. In die casting production, the mold temperature has an important influence on the casting quality, mold life and production cycle. Therefore, in modern die casting technology, the control of mold temperature has become an indispensable process means, so a die casting mold with efficient heat dissipation is required.

[0003] In the prior art, a Chinese patent document with publication number CN214079167U, A die-casting mold with efficient heat dissipation, proposes a die-casting mold with efficient heat dissipation. The die-casting mold with efficient heat dissipation has heat dissipation holes and ventilation ducts opened on the front of the die-casting mold body to dissipate the heat in the die-casting mold body. At the same time, two fans blow air towards the die-casting mold body to dissipate heat, thereby achieving the purpose of promoting heat dissipation. However, consistent with the traditional method, the above technical solution only cools the casting by setting two fans, and the cooling effect is not obvious in a short time, which is not conducive to the rapid production of the die-casting mold. Therefore, the present application discloses a die-casting mold with efficient heat dissipation to meet the needs of rapid cooling of the die-casting mold to improve production efficiency.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 to 5 As shown, a die-casting mold with efficient heat dissipation includes: a bracket 1, a supporting platform 2, two shells 7 and a die-casting assembly, the supporting platform 2 is fixedly arranged above the bracket 1, the shell 7 is arranged above the supporting platform 2, and pipes 8 are arranged inside the shell 7, and the pipes 8 are arranged inside the shell 7 in a circuitous manner. A protective shell 11 is fixedly connected above the pipe 8, and a turbofan 15 is arranged inside the protective shell 11. The protective shell 11 is fixedly connected above the pipe 8, and the pipe 8 is connected to the inside of the protective shell 11 through a slot, and the turbofan 15 is located at the slot opened in the pipe 8 inside the protective shell 11. The turbofan 15 5 is provided with a rotating rod 13, and the end of the rotating rod 13 away from the turbofan 15 penetrates the protective shell 11 and is provided with a fan 10, and the side of the protective shell 11 away from the rotating rod 13 is provided with a temperature control component 12, and a cavity for arranging the pipeline 8 is opened inside the shell 7; the die-casting component includes a cylinder 5, a push rod 6, a limit rod 14, a die-casting mold 18 and a feed port 19, the die-casting mold 18 is fixedly installed inside the shell 7, the feed port 19 is opened above the shell 7 and penetrates the shell 7 and the die-casting mold 18, and the die-casting components are used to cooperate with each other to form a complete mold for basic die-casting work. The die-casting mold is cooled from the inside to the outside by providing a circuitous coolant pipe 8 and circulating the coolant, and the fan 10 is used to assist in air convection, which complement each other to increase the cooling effect and enhance the practicability of the device. The design of the protective shell 11 can better protect the power transmission from external forces that affect the operation effect of the device. During use, when the temperature inside the die-casting mold rises, the temperature control component 12 will respond in time to form a circuit path, so that the water pump 16 works, thereby driving the coolant to enter the pipe 8 and circulate. When flowing through the pipe 8 inside the protective shell 11, it will drive the turbofan 15 to rotate, thereby driving the fan 10 to rotate to blow air to the inside of the device, thereby achieving an efficient cooling effect.

[0028] Further, such as Figure 1 As shown, cylinders 5 are provided on both sides of the support platform 2, and the cylinders 5 are provided on both sides of the support platform 2. A push rod 6 is fixedly connected to a movable end of the cylinder 5, and the other end of the push rod 6 is fixed to a shell 7. Two limit rods 14 are provided inside the support platform 2, and the shell 7 is sleeved on the limit rods 14. The setting of the cylinder 5 enables the device to perform die-casting more safely and stably. The limit rods 14 can ensure that the die-casting mold always maintains a fixed position, ensuring the stable operation of the device. During use, when the cylinder 5 pushes the push rod 6 to push the mold together, the molten liquid is poured into the mold for die-casting.

[0029] Further, such as Figure 1As shown, a cross bar 4 is provided inside the bracket 1, a coolant pool 3 is fixedly provided above the cross bar 4, a water pump 16 is provided inside the coolant pool 3, and the cross bar 4 fixes the coolant pool 3 at the lower position of the device. The water pump 16 can cooperate with the liquid cooling system to perform circulation cooling to improve the cooling efficiency.

[0030] Further, such as Figure 2 As shown, an insect-proof net 9 is provided on one side of the shell 7, a protrusion is provided on the top of the shell 7 near the insect-proof net 9, and insect-proof nets 9 are provided at both ends of the protrusion. An air duct (not shown in the figure) is also provided inside the shell 7. The insect-proof net 9 can prevent debris from entering the inside of the device during the operation of the device, thereby causing damage to the device and limiting its function. The design of the air duct can ensure smooth airflow inside the device and improve the cooling efficiency of the device.

[0031] Further, such as Figure 1 As shown, both ends of the pipe 8 pass through the outer wall of the shell 7, and the outer side of the pipe 8 is connected to the water pump 16 inside the cooling liquid pool 3 below by a hose (not shown in the figure) to form a passage. The hose is designed to better cooperate with the overall device to maintain a stable position and sound functions during movement, thereby improving the practicality of the device.

[0032] Further, such as Figure 5 As shown, the water pump 16 is connected to the power supply 17 through the circuit, and a circuit path is formed through the temperature control component 12.

[0033] Further, such as Figure 3 As shown, a rubber sealing gasket (not shown in the figure) is provided at a position where the rotating rod 13 passes through a side wall of the pipe 8. The design of the sealing gasket can better maintain the flow of coolant to drive the rotation of the turbofan 15 but will not flow out from the inside of the pipe 8, thereby improving the practicality of the device.

[0034] Further, such as Figure 4 As shown, the temperature control component 12 is composed of a U-shaped and an I-shaped metal sheet, wherein the U-shaped sheet is a conductive metal that deforms when heated, and the I-shaped sheet is a conductive metal that does not deform significantly when heated. The design of the bimetallic temperature control component 12 is more cost-effective, and it cools down when needed and does not start when not needed, thereby avoiding waste of resources and improving the practicality of the device. During operation, when the temperature inside the die-casting mold rises, the U-shaped metal sheet in the temperature control component 12 begins to deform, the angle of the U-shape increases, and the two endpoints begin to move away from each other until one side of the U-shaped metal sheet contacts the I-shaped metal sheet to form a circuit path. At this time, the device is running, and when the temperature drops, the U-shaped metal sheet begins to shrink. When the U-shaped metal sheet is no longer in contact with the I-shaped metal sheet, the device circuit is disconnected and the device stops running.
