[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This embodiment proposes an automobile chassis aluminum profile extrusion die, comprising a main support frame 1; a lower die 2 is installed on the inner side of the bottom of the main support frame 1, the main support frame 1 is used to slide and support an upper die 3, and the lower die 2 cooperates with the upper die 3 to extrude and form the aluminum profile of the automobile chassis; an upper die 3 is also slidably installed on the inner side of the main support frame 1, and the upper die 3 cooperates with the lower die 2 to extrude and form the aluminum profile of the automobile chassis.

[0029] A hydraulic cylinder 4 is fixed on the inner side of the top of the main support frame 1, and the bottom end of the hydraulic cylinder 4 is fixedly connected to the top of the upper mold 3. When the hydraulic cylinder 4 is extended or retracted, it can drive the upper mold 3 to move up and down; a main water inlet pipe 5 is connected to the left side of the upper mold 3. When in use, the main water inlet pipe 5 can be connected to an external coolant pump. The coolant in the main water inlet pipe 5 can enter the cavity inside the upper mold 3 and the lower mold 2 to play a cooling role.

[0030] A water inlet connector 6 is provided at the bottom of the main water inlet pipe 5. When the lower mold 2 and the upper mold 3 are tightly closed, the raised frame at the bottom of the water inlet connector 6 will be tightly fitted with the opening at the top of the lower water inlet pipe 8, so that the coolant in the main water inlet pipe 5 can flow into the lower water inlet pipe 8 through the water inlet connector 6; an upper water outlet pipe 7 is connected to the right side of the upper mold 3. When the lower mold 2 and the upper mold 3 are tightly closed, the bottom of the upper water outlet pipe 7 will be tightly fitted with the raised frame at the top of the water outlet connector 10. Therefore, the coolant that has absorbed the heat in the upper mold 3 will flow into the main water outlet pipe 9 through the upper water outlet pipe 7 and the water outlet connector 10 and be discharged outward; a lower water inlet pipe 8 is connected to the left side of the lower mold 2. When the lower mold 2 and the upper mold 3 are tightly closed, the raised frame at the bottom of the water inlet connector 6 will be tightly fitted with the opening at the top of the lower water inlet pipe 8. Thereby, the coolant in the main water inlet pipe 5 can flow into the lower water inlet pipe 8 through the water inlet connector 6; a main water outlet pipe 9 is connected to the right side of the lower mold 2, and the main water outlet pipe 9 is used to discharge the coolant that has absorbed the heat to the outside to realize circulation; a water outlet connector 10 is arranged on the top of the main water outlet pipe 9, and when the lower mold 2 and the upper mold 3 are tightly closed, the bottom of the upper water outlet pipe 7 will be tightly fitted with the raised frame on the top of the water outlet connector 10, so the coolant that has absorbed the heat in the upper mold 3 will flow into the main water outlet pipe 9 through the upper water outlet pipe 7 and the water outlet connector 10 and be discharged to the outside; eight inner partitions 11 are fixed at equal distances on the inner sides of the lower mold 2 and the upper mold 3, and the inner partitions 11 are used to separate channels for the flow of coolant, and can increase the contact area of ​​the coolant for absorbing heat, thereby improving the heat dissipation effect.

[0031] Two water guide plates 12 are fixed on the inner sides of the lower mold 2 and the upper mold 3. When the coolant in the main water inlet pipe 5 flows into the upper mold 3 and the coolant in the lower water inlet pipe 8 flows into the lower mold 2, they will first hit the surface of the water guide plate 12 and disperse everywhere, so these coolants will evenly flow into the nine long strip channels separated by the inner partition 11.

[0032] In the present disclosure, Figure 3 As shown, the upper water outlet pipe 7 and the lower water inlet pipe 8 are both L-shaped pipes, and the bottom of the upper water outlet pipe 7 is open, and the top of the lower water inlet pipe 8 is open. When the lower mold 2 and the upper mold 3 are tightly closed, the raised frame at the bottom of the water inlet connector 6 will be tightly fitted with the opening at the top of the lower water inlet pipe 8, so that the coolant in the main water inlet pipe 5 can flow into the lower water inlet pipe 8 through the water inlet connector 6. At the same time, the bottom of the upper water outlet pipe 7 will be tightly fitted with the raised frame at the top of the water outlet connector 10. Therefore, the coolant that has absorbed the heat in the upper mold 3 will flow into the main water outlet pipe 9 through the upper water outlet pipe 7 and the water outlet connector 10 and be discharged outward.

[0033] In the present disclosure, Figure 3-Figure 6As shown, a rectangular cavity is provided inside the lower mold 2 and the upper mold 3, and eight inner partitions 11 separate the rectangular cavity into nine long strip channels. When the coolant enters the rectangular cavity inside the lower mold 2 and the upper mold 3, it will evenly flow into the nine long strip channels separated by the inner partitions 11, ensuring uniform adsorption of heat in the lower mold 2 and the upper mold 3, and then the coolant will flow from left to right in the long strip channels separated by the inner partitions 11.

[0034] In the present disclosure, Figure 1-Figure 3 As shown, a rectangular frame is provided at the bottom of the water inlet connector 6 and the top of the water outlet connector 10, and when the lower mold 2 and the upper mold 3 are tightly fitted, the top of the lower water inlet pipe 8 will be embedded in the rectangular frame at the bottom of the water inlet connector 6, and the bottom of the upper water outlet pipe 7 will be embedded in the rectangular frame at the top of the water outlet connector 10. When the lower mold 2 and the upper mold 3 are tightly closed, the raised frame at the bottom of the water inlet connector 6 will be tightly fitted with the opening at the top of the lower water inlet pipe 8, so that the coolant in the main water inlet pipe 5 can flow into the lower water inlet pipe 8 through the water inlet connector 6, and at the same time, the bottom of the upper water outlet pipe 7 will be tightly fitted with the raised frame at the top of the water outlet connector 10. Therefore, the coolant that has absorbed heat in the upper mold 3 will flow into the main water outlet pipe 9 through the upper water outlet pipe 7 and the water outlet connector 10 and be discharged outward.

[0035] In the present disclosure, Figure 3-Figure 6 As shown, a number of round rods are evenly spaced in the long strip channel separated by the inner partition 11, and the inner partition 11 and the round rods are both made of steel structures. During use, the coolant will flow from left to right in the long strip channel separated by the inner partition 11. During this process, the coolant will evenly contact the inner partition 11 and the round rods between the inner partitions 11. Because the inner partition 11 and the round rods between the inner partitions 11 will also absorb the heat on the lower mold 2 and the upper mold 3, the contact area of ​​the coolant for absorbing heat can be increased, thereby improving the heat dissipation effect.

[0036] In the present disclosure, Figure 3-Figure 5 As shown, the water guide plates 12 are composed of two eight-shaped rectangular plates, and the water guide plate 12 inside the lower mold 2 is located at the interface of the lower water inlet pipe 8, and the water guide plate 12 inside the upper mold 3 is located at the interface of the main water inlet pipe 5. When the coolant in the main water inlet pipe 5 flows into the upper mold 3 and the coolant in the lower water inlet pipe 8 flows into the lower mold 2, they will first hit the surface of the water guide plate 12 and disperse everywhere, so these coolants will evenly flow into the nine long strip channels separated by the inner partition 11.

[0037] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6As shown, the bottom outer wall of the upper water outlet pipe 7 and the top outer wall of the lower water inlet pipe 8 are wrapped with a layer of rubber, and the inner walls of the rectangular frames at the bottom of the water inlet connector 6 and the top of the water outlet connector 10 are also wrapped with a layer of rubber. When the lower mold 2 and the upper mold 3 are closed, the raised frame at the bottom of the water inlet connector 6 will fit tightly with the opening at the top of the lower water inlet pipe 8, and at the same time, the bottom of the upper water outlet pipe 7 will fit tightly with the raised frame at the top of the water outlet connector 10. At this time, these rubbers will also fit tightly, thereby ensuring the sealing of the connection position.

[0038] The working principle of this embodiment: when the device is used to extrude the aluminum profile of the automobile chassis, the hydraulic cylinder 4 is first controlled to contract to drive the upper mold 3 to move upward inside the main support frame 1, and then the heated aluminum rod can be placed on the inner side of the top of the lower mold 2, and the main water inlet pipe 5 is connected to the external coolant pump, and then the main water outlet pipe 9 is connected to the external coolant recovery tank, and then the hydraulic cylinder 4 can be controlled to extend to push the upper mold 3 to move downward inside the main support frame 1. In this process, the upper mold 3 will be tightly closed with the lower mold 2 to extrude the aluminum profile, and when the lower mold 2 and the upper mold 3 are tightly closed, the raised frame at the bottom of the water inlet connector 6 will be tightly fitted with the opening at the top of the lower water inlet pipe 8, so that the coolant in the main water inlet pipe 5 can flow into the lower water inlet pipe 8 through the water inlet connector 6, and then the coolant in the main water inlet pipe 5 will flow into the upper mold 3 for cooling, and the coolant in the lower water inlet pipe 8 will flow into the lower mold 2 for cooling, wherein the main water inlet pipe When the coolant in 5 flows into the upper mold 3 and the coolant in the lower water inlet pipe 8 flows into the lower mold 2, they will first hit the surface of the water guide plate 12 and disperse everywhere. Therefore, these coolants will evenly flow into the nine long strip channels separated by the inner partition 11, ensuring uniform adsorption of heat in the lower mold 2 and the upper mold 3. Then these coolants will flow from left to right in the long strip channels separated by the inner partition 11. In this process, the coolant will evenly contact the inner partition 11 and the round rods between the inner partitions 11. Because the inner partition 11 and the round rods between the inner partitions 11 will also adsorb the heat on the lower mold 2 and the upper mold 3, the contact area of ​​the coolant adsorbing heat can be increased, and the heat dissipation effect can be improved. Finally, the coolant that has absorbed the heat in the lower mold 2 will be directly discharged to the outside through the main water outlet pipe 9, and the coolant that has absorbed the heat in the upper mold 3 will flow into the main water outlet pipe 9 through the upper water outlet pipe 7 and the water outlet connector 10 and be discharged to the outside.
