Description

Technical Field

[0001] This utility model relates to the field of wheel seat structure manufacturing technology, and in particular to a die-casting mold for wheel seat production. Background Technology

[0002] The wheel seat structure is ring-shaped. Conventional die-casting molds use four core-pulling structures to ensure the ring structure is formed. However, using four core-pulling structures greatly increases the manufacturing cost of the die-casting mold. To solve this problem, the mold needs to be modified. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a die-casting mold for wheel seat production, which has the characteristics of simplifying mold structure and reducing mold cost.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a die-casting mold for wheel seat production is provided, including an upper mold, a lower mold, and mold feet. The upper mold and the lower mold are stacked vertically. A mold foot is installed on the lower end face of the lower mold. An upper mold core and a lower mold core are stacked vertically between the upper mold and the lower mold, forming a mold cavity structure. A left core-pulling structure is installed on the left side between the upper mold and the lower mold, and a right core-pulling structure is installed on the right side between the upper mold and the lower mold. An ejector plate structure that moves vertically is installed on the mold feet. A core-pulling and receiving groove penetrating both sides is provided in the middle of the lower mold core. A lower forming boss is provided in the middle of the lower mold core. A central rib structure is provided on the upper surface of the lower forming boss. A gate structure is provided on the left end of the upper mold. A main runner groove is provided on the lower end face of the upper mold core. A main runner groove is provided between the gate structure and the mold cavity structure.

[0005] In this technical solution, a core-pulling storage groove is set to accommodate the left and right core-pulling structures, ensuring that the left and right core-pulling structures can form a ring structure. Compared with the original four core-pulling structures, the overall cost of this technical solution will be greatly reduced. At the same time, by designing the gate structure and the main runner, it is convenient for the aluminum liquid to be injected into the mold cavity structure.

[0006] As a supplement to this technical solution, the lower mold core has a limiting protrusion at the middle of the front and rear side walls of the core-pulling and receiving groove, which limits the left core-pulling structure and the right core-pulling structure. In this technical solution, the limiting protrusion is used to limit the right core-pulling structure and the left core-pulling structure, so that the right core-pulling structure and the left core-pulling structure can be inserted into place.

[0007] As a supplement to this technical solution, the left core-pulling structure includes a left slider, an inclined guide post, and a left core-pulling block. The left slider is installed at the left position of the upper and lower molds. A left core-pulling block for inserting into the mold cavity structure is installed on the right end of the left slider. Two inclined guide posts are installed side by side on the left side of the upper mold. The lower end of the inclined guide post is inclined to the left and passes through the left slider. The inclined guide post is used to guide the left slider to open, ensuring that the left core-pulling block is demolded.

[0008] As a supplement to this technical solution, the right core-pulling structure includes a right mold frame, a right core-pulling slider, and a right core-pulling block. The right mold frame is installed on the right side of the lower mold, and a right hydraulic cylinder with its main shaft facing left is installed on the right mold frame. The right core-pulling slider, which is connected to the main shaft of the right hydraulic cylinder, is installed inside the right side of the upper and lower molds. The right core-pulling block is installed on the left side of the right core-pulling slider.

[0009] As a supplement to this technical solution, the lower end face of the upper mold core is provided with an upper slag bag structure that communicates with the upper end of the mold cavity structure.

[0010] As a supplement to this technical solution, overflow groove structures are provided on the left and right sides of the lower forming boss. By providing overflow groove structures, excess aluminum liquid can be easily collected, ensuring product quality.

[0011] As a supplement to this technical solution, the upper end face of the lower mold core is symmetrically provided with four groove structures, and the lower end face of the upper mold core is provided with four positioning protrusions that correspond one-to-one with the groove structures.

[0012] Beneficial effects: This utility model relates to a die-casting mold for wheel seat production. By setting a core-pulling storage groove to accommodate the left and right core-pulling structures, the left and right core-pulling structures can be formed into a ring structure. Compared with the original four core-pulling structures, the overall cost of this technical solution will be greatly reduced. At the same time, by designing the gate structure and main runner, it is convenient for the aluminum liquid to be injected into the mold cavity structure, which has the characteristics of simplifying the mold structure and reducing the mold cost.
