[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figure 1-6 A die-casting mold for a radiator housing of a new energy vehicle charging pile, comprising: Support base 1, with fixed mold base 2 fixedly connected to the top of support base 1, and assembly cavity 3 opened at the top of fixed mold base 2, with central forming mold base 4 embedded in the middle of assembly cavity 3. The mold assembly is located inside the assembly cavity 3 and is used to cooperate with the central forming mold base 4 to form a fixed mold for the complete heat sink housing; The moving mold base 7 has a moving mold assembly 8 at the bottom center. The moving mold assembly 8 is used to cooperate with the middle forming mold base 4 and the mold assembly to form a complete cavity. In this embodiment, a limiting hole 15 is provided at the top of the fixed mold base 2, and a stabilizing rod 16 adapted to the limiting hole 15 is fixedly connected to the bottom of the moving mold base 7. By setting the limiting hole 15 and the stabilizing rod 16, when the moving mold base 7 approaches the fixed mold base 2, the stabilizing rod 16 is first aligned with the limiting hole 15. In the subsequent mold closing process, the displacement of the stabilizing rod 16 inside the limiting hole 15 can be used to guide the assembly position of the moving mold base 7 to ensure the mold closing accuracy. In this embodiment, vacuum connectors 17 are provided at both ends of the top of the fixed mold base 2 and at both ends of the bottom of the moving mold base 7. The vacuum connectors 17 on the fixed mold base 2 are connected to the middle forming mold base 4, and the vacuum connectors 17 on the moving mold base 7 are connected to the top forming cavity 10. By setting the vacuum connectors 17, after the top forming cavity 10 and the middle forming mold base 4 are closed, the external vacuum equipment is connected to the vacuum connectors 17, and the gas in the cavity can be extracted, thereby controlling the pressure in the cavity. In this embodiment, the molding assembly includes: Four molding seats 5 are slidably connected to the four ends of the assembly cavity 3. Cylinders 6 are fixedly connected to the four ends of the fixed mold seat 2, and the output ends of the four cylinders 6 are respectively connected to the four molding seats 5. In this embodiment, positioning frames 18 are fixedly connected to all four ends of the fixed mold base 2, and the four positioning frames 18 correspond to the four forming seats 5 respectively. The cylinder 6 is connected to one end of the positioning frame 18 by bolts. The positioning frame 18 is U-shaped. Due to the shape characteristics of the positioning frame 18, the positioning frame 18 has space for assembling the cylinder 6, and can also separate the cylinder 6 from the fixed mold base 2, so that there is space for the forming seat 5 to move between the cylinder 6 and the fixed mold base 2. In this embodiment, each of the multiple molding seats 5 has a mold groove at one end near the middle molding mold seat 4, and the outline of the mold groove is adapted to the partial edge outline of the heat sink housing of the new energy vehicle charging pile.

[0018] Example 2: Please see Figure 1-6 This embodiment provides a technical solution based on Embodiment 1: the moving model assembly 8 includes: The moving mold body 9 is embedded in the middle of the bottom end of the moving mold base 7. A top forming cavity 10 is opened in the middle of the bottom end of the moving mold body 9. A support strip 12 is fixedly connected inside the top forming cavity 10. An insert 13 is fixedly connected to both ends of the support strip 12. An exhaust hole groove is opened at the bottom end of the insert 13. Multiple forming strips 14 are fixedly connected to both sides of the insert 13. More specifically, due to the large clamping force of the heat dissipation fins, in this embodiment, the moving mold body 9 is provided with an anti-top structure, which includes: An anti-top pin is installed on the moving mold body 9, corresponding to the middle forming mold base 4; The driving component, used to drive the ejector pin, compresses or pushes it back when the mold is closed, making room for the molten metal. When the mold is opened, a spring or hydraulic cylinder pushes the ejector pin out, helping the casting to detach from the mold. By using an inverted top structure, manual intervention can be reduced, thereby improving production efficiency and product quality. This is a mature existing technology and will not be elaborated further here. In this embodiment, a flow channel 19 is provided at the top of the moving mold base 7, and a flow channel 11 communicating with the flow channel 19 is provided at one end of the moving mold body 9 near the flow channel 19. Through the structural cooperation of the flow channel 11 and the flow channel 19, the raw material of the heat sink shell of the new energy vehicle charging pile can be conveniently injected into the cavity.

[0019] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0020] Working principle: First, the top of the moving mold base 7 is assembled with the top of the fixed mold base 2. Then, the cylinder 6 is activated to push the molding base 5 towards the middle molding mold base 4 until the molding base 5 contacts the middle molding mold base 4, so that a complete heat sink shell is formed between the middle molding mold base 4, the molding base 5 and the top molding cavity 10. Then, the raw material is introduced into the cavity through the guide channel 19 and the flow channel 11, so that the heat sink shell is formed in the cavity. Furthermore, since the heat dissipation fins of the heat sink shell of the new energy vehicle charging pile are relatively high and dense, the presence of the insert 13 and the forming strip 14 in the embedded state can provide space for the forming of the heat dissipation fins and ensure the forming quality of the heat dissipation fins. After molding, the moving mold base 7 is separated from the fixed mold base 2, and the cylinder 6 is activated to move the molding base 5 away from the middle molding mold base 4, thereby separating the new energy vehicle charging pile radiator shell from the molding base 5. Then the molded new energy vehicle charging pile radiator shell can be transferred.
