Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, and more specifically, to a die casting mould for a car seat bracket. Background Art

[0002] Die casting mold is a tool for casting metal parts, a tool that completes the die casting process on a special die casting mold forging machine. The basic process of die casting is: the molten metal is first forged into the mold cavity at a low speed or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, eliminating the shrinkage and porosity defects of the blank and making the internal structure of the blank reach the broken grains in the forged state.

[0003] The die-casting mold is divided into a fixed mold and a movable mold. After the fixed mold and the movable mold are combined, the metal in the cavity is shaped. The die-casting mold for producing automobile seat brackets has cavities on both the fixed mold and the movable mold. When the mold is opened, metal parts are easy to stick to the cavity. If they stick to the fixed mold cavity, they can be ejected by the ejector pin, but if they stick to the movable mold cavity, they generally need to be removed manually, which is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is that metal parts stick to the cavity, and it is time-consuming and laborious to remove them manually. Therefore, a die-casting mold for an automobile seat bracket is provided to solve the above problem. When the fixed mold and the movable mold are opened, the metal parts in the cavity can be pre-detached, thereby achieving the effect of saving time and labor.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A die-casting mold for a car seat bracket comprises a movable mold located at an upper portion and a fixed mold located at a lower portion, a stripper plate is arranged between the movable mold and the fixed mold, and the stripper plate is movably connected to the cavity surface of the movable mold;

[0007] The unloading plate is provided with a through slot corresponding to the cavity position, and movable connecting parts and tensioning sleeves are arranged on both sides of the through slot of the unloading plate. The top end of the movable connecting part is fixedly connected to the cavity surface of the movable mold, and a tensioning cone for cooperating with the tensioning sleeve is arranged on the cavity surface of the movable mold.

[0008] Preferably, the height of the movable connecting piece is greater than the thickness of the unloading plate, the axial section of the movable connecting piece is set to an inverted T shape, and a groove for the bottom end of the movable connecting piece to be embedded is provided on the cavity surface of the fixed mold.

[0009] Preferably, the height of the movable connecting member is smaller than the thickness of the unloading plate, and a tension spring is connected between the top of the movable connecting member and the cavity surface of the movable mold.

[0010] Preferably, an insert is provided on the side wall of the through groove, the insert extends toward the cavity of the movable mold, and an avoidance notch for inserting the insert is provided on the side wall of the cavity of the movable mold.

[0011] Preferably, the side wall of the insert is in sliding friction contact with the side wall of the avoidance gap.

[0012] Preferably, a countersunk hole is provided at the bottom of the through groove.

[0013] Preferably: a push rod is provided in the cavity of the fixed mold.

[0014] The utility model has the following beneficial effects: when closing the mold, the stripper plate moves downward with the movable mold and is used in conjunction with the fixed mold. After the metal parts in the cavity are finalized, the movable mold moves upward before the stripper plate under the action of the tension sleeve and the tension cone. The stripper plate locks the metal parts in the cavity of the movable mold to prevent the metal parts from sticking to the cavity of the movable mold. Then, the stripper plate is driven by the movable connecting piece to separate from the fixed mold. The metal parts on the stripper plate remain in the cavity of the fixed mold due to their own gravity and the friction between the metal parts and the cavity of the fixed mold. Finally, they are ejected by the ejector pin in the cavity of the fixed mold, thereby achieving the effect of rapid demoulding. BRIEF DESCRIPTION OF THE DRAWINGS
