Description

Technical Field

[0001] This utility model belongs to the field of die-casting mold technology for housings, specifically a die-casting mold for electronic control housings of new energy vehicles. Background Technology

[0002] The electrical control box of a new energy vehicle is one of the core components of an electric vehicle. It carries the high-voltage electrical components and control units of the vehicle and plays a role in protection, support and heat dissipation. In the process of reinforcing the electrical control box of a new energy vehicle, die casting molds are used. Die casting molds are a tool for casting metal parts. They are tools that complete the die casting process on a special die casting forging machine. Therefore, a die casting mold for the electrical control box of a new energy vehicle is needed.

[0003] Existing die-casting molds for new energy vehicle electronic control boxes have certain drawbacks. When using existing die-casting molds for new energy vehicle electronic control boxes, they are usually cooled by natural cooling or liquid cooling. However, natural cooling takes a long time, while liquid cooling will cause the temperature of the coolant to rise during use, thus reducing the cooling efficiency. To improve the cooling efficiency, the coolant must be replaced manually in a timely manner. However, manual replacement of coolant will inevitably lead to a decrease in production efficiency and cannot meet people's needs. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1 Please see Figure 1 - Figure 4This application provides a die-casting mold for a new energy vehicle electronic control box, including: a mold body 1 for producing a new energy vehicle electronic control box and a cooling mechanism detachably mounted on the mold body 1; the cooling mechanism includes a first heat dissipation structure 2 symmetrically arranged on both sides of the outer surface of the mold body 1 for heat dissipation, a second heat dissipation structure 3 arranged below the first heat dissipation structure 2, a heat dissipation duct 4 arranged below the second heat dissipation structure 3 for heat dissipation of the second heat dissipation structure 3, a guide structure arranged above the first heat dissipation structure 2 and matched with the heat dissipation duct 4, and a heat dissipation component arranged inside the mold body 1 and connected to the first heat dissipation structure 2 and the second heat dissipation structure 3 respectively. The first heat dissipation structure 2 and the second heat dissipation structure 3 cooperate to dissipate heat from the mold body 1, and the heat dissipation duct 4 and the guide structure cooperate to dissipate heat from the first heat dissipation structure 2 and the second heat dissipation structure 3.

[0022] In this embodiment, both the first heat dissipation structure 2 and the second heat dissipation structure 3 include a heat dissipation substrate 6 disposed on the outer surface of the mold body 1 and heat dissipation fins 5 disposed on both sides of the outer surface of the heat dissipation substrate 6. The heat dissipation substrate 6 ensures smooth heat transfer, and the heat dissipation substrate 6 and the heat dissipation fins 5 work together to dissipate heat from the mold body 1.

[0023] In this embodiment, the heat dissipation component includes heat-absorbing plates 7 symmetrically arranged inside the mold body 1 and several sets of heat-conducting rods 8 vertically arranged on the outer surface of the heat-absorbing plates 7 and connected to the heat dissipation substrate 6. The mold body 1 is provided with a die-casting cavity. The heat-absorbing plates 7 can absorb the heat from the die-casting cavity inside the mold body 1 and transfer the heat to the heat dissipation substrate 6 through the heat-conducting rods 8 for heat dissipation.

[0024] In this embodiment, several sets of blowers 9 are installed at equal intervals on the heat dissipation duct 4. One end of the heat dissipation duct 4 is connected to a blower. The air guiding structure includes a guide nozzle 10 installed on the mold body 1 and aligned with the blower 9, and a guide pipe 11 installed inside the mold body 1 and connected to the guide nozzle 10. A connecting pipe 12 is provided on the mold body 1 to connect the two sets of guide pipes 11. One end of the connecting pipe 12 can be connected to an air suction device. The blower blows air onto the heat dissipation substrate 6 and heat dissipation fins 5 through the heat dissipation duct 4 and the blower 9. The air suction device can absorb the air blown by the heat dissipation duct 4 and the blower 9 through the guide nozzle 10 and the guide pipe 11, thereby accelerating the airflow and enabling the heat dissipation fins 5 to dissipate heat quickly.

[0025] In summary, after the die casting of the new energy vehicle electronic control box is completed using the mold body 1, the heat absorption plate 7 absorbs the heat inside the mold body 1 and transfers the heat to the heat dissipation base plate 6 through the heat conduction rod 8, so that the heat dissipation fins 5 dissipate heat on the heat dissipation base plate 6. The blowing equipment is activated, so that the heat dissipation air pipe 4 blows air to the heat dissipation fins 5 through the blower head 9. The air suction equipment is activated, and the air blown out by the blower head 9 is absorbed and extracted through the air guide nozzle 10 and the air guide pipe 11, thereby accelerating the air flow and improving the heat dissipation efficiency of the mold body 1.

[0026] Example 2 Reference Figure 1 - Figure 2 and Figure 5 - Figure 6 This is the second embodiment of the present invention. In this embodiment, the mold body 1 includes a base 13, a lower mold 14 detachably connected to the base 13, and an upper mold 15 detachably connected to the lower mold 14. The air guide structure is detachably installed on the upper mold 15, and the heat dissipation air pipe 4 is detachably installed on the outer surface of the base 13. The upper end face of the upper mold 15 is provided with a closable liquid injection port. The upper mold 15 and the lower mold 14 cooperate to perform die casting of the electric control box of new energy vehicles.

[0027] In this embodiment, the heat dissipation assembly includes several sets of heat dissipation guide pillars 16 vertically mounted on the lower end face of the upper mold 15 and heat dissipation fin rings 17 detachably mounted on the middle of the outer surface of the heat dissipation guide pillars 16. The heat dissipation guide pillars 16 are made of heat-absorbing material. Several sets of guide grooves corresponding to the heat dissipation guide pillars 16 are opened on the lower mold 14. The heat dissipation guide pillars 16 are located on the inner side of the heat absorption plate 7. The heat dissipation guide pillars 16 have an "I" shaped structure. The heat dissipation guide pillars 16 are composed of two sets of large guide pillars and small guide pillars connecting the two sets of large guide pillars. The heat dissipation fin rings 17 are installed on the outer wall of the small guide pillars. The diameter of the heat dissipation fin rings 17 is smaller than the diameter of the large guide pillars.

[0028] In this embodiment, the cooling mechanism also includes a water-cooling structure 19 disposed inside the lower mold 14 and a water guide pipe 18 disposed on the outer surface of the lower mold 14 and connected to the water-cooling structure 19. The water-cooling structure 19 is arranged in a serpentine manner inside the lower mold 14 and surrounds the outside of the die-casting cavity. Both ends of the two sets of water guide pipes 18 are connected to a water tank and a water pump connected to the water tank. The water pump allows the liquid in the water tank to be introduced into the water-cooling structure 19 through the water guide pipes 18 to cool the lower mold 14. The water pump can be connected to a refrigeration device to improve the cooling effect of the cooling mechanism. The refrigeration device can be replaced with a heating device to heat the liquid in the water tank, thereby preheating the upper mold 15 and the lower mold 14 and improving the applicability of the water-cooling structure 19.

[0029] In summary, the heat dissipation guide pillar 16 absorbs heat inside the lower mold 14, allowing the upper mold 15 to be removed from the lower mold 14, thus removing the heat dissipation guide pillar 16 from the guide groove. The heat dissipation fin ring 17 can quickly dissipate heat from the heat dissipation guide pillar 16, thereby quickly dissipating heat from the upper mold 15. The water pump and refrigeration equipment are started, and coolant is injected into the water-cooling structure 19 through the water pipe 18, so that the coolant carries away the heat inside the lower mold 14, thereby cooling the lower mold 14.

[0030] Example 3 Reference Figure 1 - Figure 6 This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0031] The heat-absorbing plate 7, heat-conducting rod 8, heat-dissipating base plate 6, and heat-dissipating fins 5 dissipate heat to the lower mold 14 and the upper mold 15. The heat dissipation air duct 4, blower head 9, air guide nozzle 10, and air guide duct 11 accelerate airflow and dissipate heat to the heat dissipating fins 5. The heat dissipation guide post 16 and heat dissipation fin ring 17 work together to dissipate heat to the lower mold 14 and the upper mold 15. The water-cooling structure 19 and water guide pipe 18 work together to cool the lower mold 14, thereby improving the heat dissipation efficiency of the mold body 1.
