Description

Technical Field

[0001] The utility model belongs to the technical field of die-casting molds, and particularly relates to a die-casting mold. Background Art

[0002] A die-casting mold is a special tool used in the die-casting process. It is mainly used to manufacture various metal parts with complex shapes. Die-casting is an efficient casting method that can produce parts with fine details and high dimensional accuracy. This process is particularly suitable for mass production.

[0003] A die-casting mold usually consists of two parts: a front mold (the moving part) and a rear mold (the fixed part). When the molten metal is injected into the mold cavity under high pressure, these parts close tightly to form the required part shape. Once the metal cools and hardens, the mold opens and the part can be removed.

[0004] However, when preparing die-castings with relatively complex shapes, affected by the separation direction of the existing front mold and rear mold of the die-casting mold, problems such as interference between the front mold or the rear mold and the die-casting part during demolding, resulting in inability to demold, are likely to occur. Summary of the Utility Model

[0005] In view of the above existing technical problems, the utility model provides a die-casting mold to solve the problem that the existing die-casting mold is difficult to meet the production of die-castings with complex shapes, and designs a new type of die-casting mold. This die-casting mold can reduce the demolding interference problem and realize the diversity of die-casting part design.

[0006] The utility model provides a die-casting mold, which includes a front mold, a middle plate, a rear mold, an inclined sliding block and a turning block. The middle plate is detachably arranged on one side of the rear mold, the front mold is detachably arranged on one side of the middle plate, the middle plate is located between the rear mold and the front mold, a die-casting cavity is formed between the rear mold and the middle plate, an inclined communication hole communicating the die-casting cavity and the front mold is opened on the middle plate, the inclined sliding block is slidably arranged in the inclined communication hole, one end of the inclined sliding block is inserted into the die-casting cavity, and the die-casting cavity is formed by enclosing one end of the inclined sliding block, the rear mold and the middle plate. The turning block is fixed on the side of the front mold facing the middle plate, the side of the turning block facing the middle plate is an inclined surface, the other end of the inclined sliding block is slidably arranged on the inclined surface of the turning block, the front mold drives the turning block to move horizontally, and the horizontal movement of the turning block drives the inclined sliding block to slide along the inclined communication hole.

[0007] Furthermore, the rear mold is provided with an injection runner communicating with the die-casting cavity.

[0008] Further, the die-casting mold further includes ejector pins and an ejector plate. One end of each ejector pin passes through the rear mold and exposes into the die-casting cavity, and the other end of the ejector pin is connected to the ejector plate. The ejector plate is disposed on a side of the rear mold away from the middle plate in a horizontally displaceable manner.

[0009] When die-casting with this die-casting mold, the die-casting cavity is formed by enclosing one end of the inclined sliding block, the rear mold, and the middle plate. The melt is injected into the die-casting cavity and cooled to form a shape. When demolding, the front mold is first removed. At the same time, the front mold drives the turning block to move horizontally, and the horizontal movement of the turning block drives the inclined sliding block to slide along the inclined communication hole, so that the inclined sliding block is separated from the die-casting part obliquely, for demolding of some structural positions that are prone to interference during demolding; then the middle plate and the rear mold are separated, and finally the die-casting part is separated from the rear mold; this die-casting mold realizes demolding in different positions and directions, and can effectively design different demolding methods according to the shape of the die-casting part, avoid interference during demolding, and realize the flexibility and diversity of the die-casting part shape design.
