Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, and in particular relates to a pad for venting blocks in die casting molds. Background Technology

[0002] During the die casting process using die casting molds, gas exists within the mold cavity. This gas includes air and fumes generated during injection. The more gas trapped in the cavity, the more difficult it is to form high-quality, defect-free die castings. Therefore, venting is necessary, and the quality of venting directly affects the quality of the die castings.

[0003] For the purpose of venting, die casting mold frames are usually equipped with venting blocks on the moving and fixed mold plates. However, when the air impact force is large, the traditional venting blocks will break the upper and lower venting blocks protruding from the mold, affecting venting and wasting materials. To solve the above problems, we propose a pad block for venting blocks in die casting molds. Utility Model Content

[0004] The purpose of this invention is to provide a gasket for venting in die-casting molds, thereby solving existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a gasket for venting a die-casting mold, including a fixed mold and a moving mold that cooperate with each other, a fixed mold venting block disposed on the fixed mold, and a moving mold venting block disposed on the moving mold. Venting teeth are provided on the opposing surfaces of the fixed mold venting block and the moving mold venting block. The venting teeth of the fixed mold venting block and the venting teeth of the moving mold venting block cooperate with each other. The venting teeth are disposed in the middle of the two opposing surfaces of the fixed mold venting block and the moving mold venting block.

[0007] A mold pad is fixed to one side of the mold. The lower surface of the mold pad is flush with the lower surface of the mold. The upper surface of the mold pad abuts against the lower surface of the mold venting block. The position of the mold pad is adapted to the mold venting block.

[0008] A moving mold pad is fixed to one side of the moving mold. The upper surface of the moving mold pad is flush with the upper surface of the moving mold, and the lower surface of the moving mold pad abuts against the upper surface of the moving mold venting block. The position of the moving mold pad is adapted to the moving mold venting block.

[0009] Furthermore, the venting teeth include a plurality of alternating concave teeth and convex teeth, wherein the concave teeth of the fixed mold venting block match the convex teeth of the moving mold venting block, and the convex teeth of the fixed mold venting block match the concave teeth of the moving mold venting block.

[0010] Furthermore, the fixed mold is fixed on the upper surface of the worktable, and the fixed mold pad abuts against the upper surface of the worktable, which helps to limit the fixed mold pad and prevent the fixed mold pad from shifting due to excessive pressure; the moving mold is fixed on the lower surface of the moving mold frame, and the moving mold pad abuts against the lower surface of the moving mold frame, which helps to limit the moving mold pad and prevent the moving mold pad from shifting due to excessive pressure.

[0011] This utility model has the following beneficial effects:

[0012] This invention provides moving mold pads and fixed mold pads above and below the moving mold venting block and the fixed mold venting block, respectively. The moving mold pads and fixed mold pads are fixedly connected to the fixed mold and the moving mold, respectively. The upper and lower end faces of the moving mold pads are flush with the upper surface of the moving mold and the upper surface of the moving mold venting block, respectively. The two end faces of the fixed mold pads are flush with the lower surface of the fixed mold and the lower surface of the fixed mold venting block, respectively. This facilitates the protection and support of the fixed mold venting block and the moving mold venting block that protrude from the die-casting mold during venting, preventing the venting block from being broken due to excessive impact force, thus affecting the efficiency of die casting and causing unnecessary material waste.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
