[0026] The embodiments of this utility model relate to a die-casting core structure for a radiator housing, such as... Figure 1 As shown in Figure 4, the device includes an upper mold core 1, a lower mold core 2, and an end core-pulling block 3. The upper mold core 1 and the lower mold core 2 are stacked vertically. An end core-pulling block 3 is installed in the middle of the left end of the upper mold core 1 and the lower mold core 2. A shell forming protrusion 4 is provided on the left side of the upper end face of the lower mold core 2. A heat dissipation surface forming part 5 is provided on the right side of the upper end face of the lower mold core 2.

The hole forming protrusion 7 is inserted into the shell forming protrusion 4. An edge forming groove 6 is provided at the upper part of the left end of the end core-pulling block 3. An outwardly protruding part 9 is provided at the middle of the lower end of the slope structure 8. The side of the protruding part 9 that is attached to the end core-pulling block 3 adopts a demolding slope with the upper end inclined to the left.
[0027] In this technical solution, the shell forming protrusion 4 is used to facilitate the shell forming of the product, the heat dissipation surface forming part 5 is set to ensure the heat dissipation fins are formed, the end core pulling block 3 is set to facilitate the forming of the edge 22, the inclined structure 8 is set to facilitate the stable removal of the edge 22, the hole forming protrusion 7 is set to facilitate the forming of the hole 23, and the protrusion 9 and the demolding inclined surface are set to facilitate the quick removal of the end core pulling block 3 and avoid damaging the edge 22 during core pulling.
[0028] like Figure 7 As shown, as a supplement to this technical solution, an overflow slag packing groove 10 is provided in the middle of the upper end face of the shell forming protrusion 4. Several pin mounting holes 11 surrounding the overflow slag packing groove 10 are provided on the right side of the overflow slag packing groove 10. In this technical solution, the overflow slag packing groove 10 is provided to collect excess aluminum liquid, ensuring that the shell structure will not have local missing parts.
[0029] like Figure 7As shown, as a supplement to this technical solution, the front and rear edges of the heat dissipation surface forming part 5 are provided with edge forming ribs 12, and the edge forming ribs 12 are provided with a plurality of reinforcing rib forming notches 13.
[0030] Two protective baffles 24 need to be set on both sides of the heat dissipation part of the product. The protective baffles 24 can protect the heat sink structure. In order to reduce the material required for the molding of the protective baffles 24, an inward concave notch is provided on the lower side of the protective baffles 24. To facilitate the molding of the inward concave notch, a baffle forming rib 12 is designed. A reinforcing rib forming notch 13 is provided on the baffle forming rib 12, so that several reinforcing ribs are provided inside the inward concave notch, thereby ensuring the overall structural strength of the protective baffles 24.
[0031] As a supplement to this technical solution, the lower end face of the upper mold core 1 is provided with a number of heat sink forming gaps 18 arranged in a front-to-back manner. The heat sink forming gaps 18 are provided to ensure the heat sink is formed.
[0032] like Figure 5 and Figure 6 As shown, as a supplement to this technical solution, the lower mold core 2 is provided with a left flow channel groove 14 extending to the rear side of the shell forming protrusion 4, and the lower mold core 2 is provided with a right flow channel groove 15 extending to the right end of the heat dissipation surface forming part 5. The right flow channel groove 15 corresponds to the right end of the heat dissipation fin forming gap 18.
[0033] In this technical solution, a left flow channel groove 14 is provided to guide a portion of the molten aluminum to the shell forming protrusion 4. A right flow channel groove 15 is provided to facilitate the forming of the heat sink structure. The molten aluminum inlet node of the right flow channel groove 15 is located at the right end of the heat sink forming gap 18, thereby controlling the flow direction of the molten aluminum and ensuring that the flow direction matches the structure of the heat sink. This guarantees the quality of the heat sink structure. Furthermore, the dual-flow channel structure improves the injection efficiency of the molten aluminum, thus increasing the production efficiency of the product.
[0034] As a supplement to this technical solution, two side wall support forming notches 16 arranged side by side are provided at the left end of the shell forming protrusion 4. Two forming ribs 17 that match the side wall support forming notches 16 are provided on the lower end surface of the upper mold core 1. A gap is formed between the forming ribs 17 and the side wall support forming notches 16 to ensure that the shell side wall can form a reinforced structure.
[0035] As a supplement to this technical solution, two side slag packing structures 19 are provided on the left end of the lower mold core 2, which correspond one-to-one with the side wall support forming notch 16.
[0036] As a supplement to this technical solution, a core-pulling block slag-encasing groove 20 is provided at the left end of the lower mold core 2 where the core-pulling block 3 is installed.
[0037] Example
[0038] like Figure 8 As shown, the most difficult part of this product to form is the edge binding 22. Conventional core-pulling structures will damage the edge binding during the core-pulling action, while the edge binding itself is a necessary structure of the product. In order to solve this technical problem, the core-pulling part has been improved.
[0039] When this mold core is used in production, the molten aluminum is first diverted through the left flow channel groove 14 and the right flow channel groove 15, allowing the molten aluminum to be injected into the mold cavity from both parts simultaneously, improving the mold production efficiency. At the same time, the flow direction of the molten aluminum in the right flow channel groove 15 ensures that the heat sink is formed, ensuring the overall quality of the heat sink. When the mold cavity is filled, the excess molten aluminum in the middle of the product will enter the overflow slag packing groove 10, ensuring the integrity of the product. At this time, the inner ring of the product's edge 22 is a butt joint slope 21. When the product is cooled and formed and demolded, the upper mold core 1 and the lower mold core 2 are opened first, and then the core pulling action is performed. When the core is pulled, due to the demolding slope of the slope structure 8 and the protrusion 9, the butt joint slope 21 and the end core pulling block 3 can be quickly removed, avoiding damage to the edge 22. The principle is that the slope structure facilitates the release of internal stress when the molten aluminum cools, and the two slopes can avoid stress accumulation, making it easy for the end core pulling block 3 to be removed without affecting the quality of the product.
