[0002] Currently, automotive domain controllers are the core hub of a vehicle's electronic and electrical architecture, responsible for integrating and controlling multiple functional modules. Through software-defined vehicles, they enhance the functionality and intelligence of automobiles. With the accelerating trend of automotive intelligence and connectivity, domain controllers, as a crucial component of automotive electronic systems, are gradually occupying a central position in the automotive industry. The form of domain controllers may evolve into a central domain, controlling all vehicle functions through a central computing unit.

[0003] To ensure the proper functioning of the controller, its housing is typically machined as a heat-dissipating shell to allow the heat from the internal control chip to dissipate promptly. During manufacturing, the presence of screw posts within the mold can easily lead to problems such as insufficient filling, cold shuts, and severe watermarks in the product's center.

[0011] In this utility model, as a preferred embodiment, the bottom wall of the second groove section is provided with multiple grooves, and adjacent two grooves are connected by an arc protrusion.

[0012] In this utility model, as a preferred embodiment, the connecting groove segment includes a first inclined groove segment and a second inclined groove segment that are connected to each other, the first inclined groove segment is connected to the first groove segment, and the second inclined groove segment is connected to the second groove segment.

[0029] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0030] like Figures 1-5 The mold shown is for a controller heat sink housing, including an upper mold 10, a lower mold 20, and a drive component. The upper mold 10 has an upper cavity and a gating channel, and the gating channel has an inlet and an outlet. The inlet extends to the upper end face of the upper mold 10, and the outlet extends to the upper cavity. The gating channel can communicate with the flow channel of a die-casting machine 30 in the prior art. In addition, the lower mold 20 has a lower cavity 21 and multiple slag-filling grooves. The lower cavity 21 is correspondingly arranged with the upper cavity and cooperates with the upper cavity to form a molding cavity when the mold is closed. The multiple slag-filling grooves are located on the side of the lower cavity 21 and communicate with the lower cavity 21.

[0031] The aforementioned driving component can drive the upper mold 10 to move up and down, thereby driving the upper mold 10 and the lower mold 20 to open or close. The driving component can be a linear drive such as a drive cylinder or drive oil cylinder in the prior art, which drives the upper mold 10 and the lower mold 20 to move up and down directly to realize the mold opening and closing action. Alternatively, it can be driven by a drive cylinder or drive oil cylinder to move the inclined ejector block on the side of the mold, in conjunction with the guide rod on the mold, to realize the mold opening and closing action. The specific choice depends on the actual needs.

[0032] The die-casting machine 30 injects material directly through the sprue and fills the molding cavity through the gating channel. Because the mold temperature is lower than the material temperature, the high-temperature material will raise the internal temperature of the mold after passing through the mold cavity. The material that enters the mold cavity in the early stage will become cold material. After the product is filled, since multiple slag pockets are connected to the lower cavity 21, when the material fluid continues to enter, the cold material that enters the cavity first will be squeezed into the slag pocket position, so that the material that enters the mold cavity later can fill the inside of the product.

[0033] Therefore, in this application, by setting a slag pocket groove on the lower mold 20, when the material fluid of the pouring channel 11 flows in the cavity, the excess cold material fluid and the material fluid mixed with gas, impurities, etc. will flow into the slag pocket groove through the channel connected to the cavity, thereby ensuring the quality of the casting and reducing the generation of defects such as cold shut, porosity and slag inclusion.

[0034] In addition, since air entrapment usually occurs in the corners or edges of the molding cavity or in a position far from the gating channel 11 during the molding process, the slag trap is set on the side of the lower cavity 21, away from the gating channel 11 set on the upper mold 10, to ensure that cold material and gas can be effectively collected.

[0035] Furthermore, the slag bag trough includes a first trough section 221 and a second trough section 223. One end of the first trough section 221 is connected to the lower mold cavity 21, and the other end of the first trough section 221 is connected to the second trough section 223 through a connecting trough section 222, so that the second trough section 223 is lower than the first trough section 221. In this way, cold material, gas, and other impurities overflowing from the molding cavity can be guided into the slag bag trough through the first trough section 221 and introduced through an overflow port. Since there may be a lot of cold material and trapped gas in the molding cavity, the cold material and gas are guided downward to the second trough section 223, which serves as a secondary slag bag, through the connecting trough section 222, to further collect impurities and gas. In addition, the flow is smooth due to the downward flow properties.

[0036] Furthermore, the bottom wall of the second groove section 223 is provided with multiple grooves, and two adjacent grooves are connected by an arc protrusion. This can form a wave-like structure in the second groove section 223. The wave-like structure can increase the surface area and the complexity of the gas flow path in the slag pot. After the discharged fluid enters the second groove section 223 of the slag pot, the gas flows in the wave-like channel, which is easier to be divided and guided, thereby more effectively separating it from the molten metal and discharging it from the slag pot, reducing porosity defects in the mold.

[0037] Furthermore, the connecting channel 222 includes a first inclined channel and a second inclined channel that are interconnected. The first inclined channel is connected to the first channel 221, and the second inclined channel is connected to the second channel 223. Thus, after the material fluid enters the first channel 221, it can be guided downwards through the first and second inclined channels. As the material fluid flows in the inclined channels, the changes in flow velocity and direction cause a certain degree of disturbance and rotation in the molten metal, prompting impurities in the material fluid to settle more quickly to the bottom of the channels under the influence of gravity.

[0038] Furthermore, a guide element 111 can be provided at the outlet. Specifically, the guide element 111 has a guide port and multiple guide channels 112. The guide port is connected to the outlet, and the multiple guide channels 112 are connected to the guide port and are distributed at intervals in the width direction of the outlet. In this way, the material fluid entering the gating channel can enter the guide port and then be dispersed into the multiple guide channels 112. Therefore, the material fluid can be dispersed and introduced into the molding cavity, preventing the material fluid from agglomerating. During the fluid dispersion and introduction process, the temperature inside the mold can be raised more evenly; and the uneven thickness caused by material concentration during the molding process is also reduced.

[0039] Furthermore, the bottom end of the lower mold 20 is provided with a lower ejector pin 24, a lower ejector pin 24 plate 23, and an ejector plate 23 drive. The lower ejector pin 24 plate 23 is located at the bottom end of the lower mold 20 and moves up and down under the drive of the ejector plate 23 drive. The bottom end of the lower ejector pin 24 plate 23 is connected to the lower ejector pin 24 plate 23, and the top end of the lower ejector pin 24 plate 23 is movably connected to the lower mold 20 and can extend into or out of the lower cavity 21. After the mold is formed, the ejector plate 23 can be driven upward by the ejector plate 23 drive, which in turn drives the lower ejector pin 24 to move upward, ejecting the product from the mold cavity, allowing the product to be smoothly separated from the mold, facilitating product removal, and realizing automated production.

[0040] Furthermore, the top of the upper mold 10 is provided with multiple upper ejector pin assemblies 12. Each upper ejector pin assembly 12 includes an upper ejector pin 121 and an elastic member 122. The elastic member 122 provides an elastic stress that drives the upper ejector pin 121 to move downward. The upper ejector pin 121 moves downward during mold opening to extend into the upper cavity. After the molding action of the mold is completed, the elastic stress provided by the elastic member 122 drives the upper ejector pin 121 to extend into the upper cavity, allowing the upper ejector pin 121 to eject the product from above. This results in faster demolding speed, and the elastic member 122 can also act as a buffer when the upper ejector pin 121 is ejected, preventing the ejector pin from making instantaneous rigid contact with the product or other parts of the mold, reducing impact and wear, and preventing the product from being damaged or deformed by ejection.

[0041] Furthermore, the top of the upper mold 10 is provided with multiple ejector cavities 123, and each upper ejector assembly 12 is installed in each ejector cavity 123. In this way, the upper ejector assemblies 12 can be installed one-to-one in each ejector cavity 123, and the elastic part 122 of each upper ejector assembly 12 can extend and retract within the ejector cavity 123 independently without interfering with each other, and the extension and retraction process is stable.

[0042] The embodiments described are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
