Description

Technical Field

[0001] The utility model relates to the technical field of processing molds, in particular to an automobile parts processing mold. Background Art

[0002] Automotive parts processing molds are specialized mold equipment used to produce automotive components. During the automotive manufacturing process, many auto parts require processing and forming through molds to ensure their precision, quality, and consistency. Conventionally, molten metal is injected into the mold cavity, where it cools and solidifies to form the desired auto part.

[0003] After searching, the patent with announcement number CN212498578U discloses a high-strength automobile parts processing mold, which includes a lower mold and an upper mold. The surface of the upper mold is fixedly connected to the upper armor, and the surface of the lower mold is fixedly connected to the lower armor. The front and back sides of the bottom of both sides of the upper armor are fixedly connected to fixing boxes, and the front and back sides of both sides of the lower armor are fixedly connected to fixing blocks. A fixing mechanism is provided on the side of the fixing box facing the fixed block.

[0004] During use of the high-strength automobile parts processing mold mentioned above, after the upper mold is opened, the cooled and formed automobile parts may be embedded in the mold cavity of the lower mold, making it difficult to remove the cooled and formed automobile parts and inconvenient to use.

[0005] In view of the above problems, this utility model document proposes an automobile parts processing mold. Utility Model Content

[0006] The utility model provides an automobile parts processing mold, which solves the disadvantage in the prior art that after the upper mold is opened, the cooled and formed automobile parts may be embedded in the mold cavity of the lower mold, resulting in difficulty in removing the cooled and formed automobile parts and inconvenience in use.

[0007] The utility model provides the following technical solutions:

[0008] A mold for processing automobile parts, comprising:

[0009] An upper mold and a lower mold are used in conjunction with each other, wherein the top of the upper mold is connected to a hopper for adding molten metal, and a demoulding seat is provided below the lower mold. A first groove is provided in the center of the top of the demoulding seat, and the bottom of the outer wall of the lower mold is fixedly connected to the bottom of the inner wall of the first groove;

[0010] The punch assembly is provided on the demoulding seat and is used to eject the molded parts embedded in the mold cavity of the lower mold. The punch assembly includes a base plate fixedly arranged at the bottom of the demoulding seat, a hydraulic cylinder is fixedly installed in the center of the top of the base plate, and a through hole is provided in the center of the bottom of the lower mold for the output end of the hydraulic cylinder to pass through.

[0011] In a possible design, two locking blocks are symmetrically fixedly provided at the butt edges of the upper mold and the lower mold, and each set of the locking blocks is reinforced by the same fastening bolt.

[0012] In a possible design, a second groove for each set of locking blocks and fastening bolts to pass through is provided on the inner wall of the first groove.

[0013] In a possible design, a blocking block is slidably connected in the through hole. The blocking block is made of the same material as the lower mold and is used to prevent the output end of the hydraulic cylinder from being cast together with the molten metal.

[0014] In a possible design, a limit frame is fixedly provided on the bottom of the upper mold, and a plug-in slot for plugging in the limit frame is provided on the top of the lower mold.

[0015] In a possible design, a handle is fixedly provided at the center of the top of the upper mold.

[0016] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0017] In this application, when in use, molten metal is injected from the injection hopper into the upper mold and the lower mold that are locked together. After the part is cooled and formed, the fastening bolts on both sides are unscrewed, the upper mold is removed, and then the part embedded in the cavity of the lower mold is ejected by extending the output end of the hydraulic cylinder, thereby quickly completing the separation of the part from the cavity of the lower mold, which is convenient to use.

[0018] The barrier block can block the molten metal and the output end of the hydraulic cylinder, thereby preventing the output end of the hydraulic cylinder from being cast together with the molten metal. In addition, since the parts still need to be polished after being taken out, the excess parts extending into the through hole can be removed in the subsequent polishing process without affecting the quality of the parts.

[0019] The utility model has the following beneficial effects:

[0020] The utility model is provided with a punch assembly, which can eject the parts embedded in the lower mold cavity, thereby quickly completing the separation of the parts from the lower mold cavity. It is easy to use, and the blocking block can block the molten metal and the output end of the hydraulic cylinder, thereby preventing the output end of the hydraulic cylinder from being cast together with the molten metal.

[0021] The utility model can prevent the upper mold and the lower mold from being misplaced by arranging the limit frame and the plug-in groove, and also helps to improve the sealing performance of locking the upper mold and the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS

A demoulding seat 6 is provided below the lower mold 2. A first groove 7 is provided in the center of the top of the demoulding seat 6. The bottom of the outer wall of the lower mold 2 is fixedly connected to the bottom of the inner wall of the first groove 7.

[0033] Two locking blocks 3 are symmetrically fixed at the butt edges of the upper mold 1 and the lower mold 2. Each set of locking blocks 3 is reinforced by the same fastening bolt 4. A second groove 8 is provided on the inner wall of the first groove 7 for each set of locking blocks 3 and fastening bolt 4 to pass through. Each set of locking blocks 3 is locked by the fastening bolt 4, thereby reinforcing the upper mold 1 and the lower mold 2.

[0034] The punch assembly is provided on the demoulding seat 6 and is used to eject the molded parts embedded in the cavity of the lower mold 2. The punch assembly includes a base plate 9 fixedly provided on the bottom of the demoulding seat 6. A hydraulic cylinder 10 is fixedly installed in the center of the top of the base plate 9. A through hole 11 for the output end of the hydraulic cylinder 10 to penetrate is provided in the center of the bottom of the lower mold 2. When in use, molten metal is injected from the injection hopper 5 into the upper mold 1 and the lower mold 2 that are docked and locked. After the part is cooled and formed, the fastening bolts 4 on both sides are unscrewed, and the upper mold 1 is removed. Then, the output end of the hydraulic cylinder 10 is extended to eject the part embedded in the cavity of the lower mold 2, thereby quickly completing the separation of the part from the cavity of the lower mold 2. It is easy to use.

[0035] A blocking block 12 is slidably connected in the through hole 11. The blocking block 12 is made of the same material as the lower mold 2 and is used to prevent the output end of the hydraulic cylinder 10 from being cast together with the molten liquid. By setting the blocking block 12, the molten liquid and the output end of the hydraulic cylinder 10 can be blocked, thereby preventing the output end of the hydraulic cylinder 10 from being cast together with the molten liquid.

[0036] This application can be used for automobile parts processing, and can also be used in other fields applicable to this application.
