Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for clutch production. Background Art

[0002] An automotive clutch is a component directly connected to the engine in the automotive transmission system. Its main function is to control the connection and disconnection between the engine and the automotive transmission system, and realize the transmission and cut-off of power. Since the clutch housing has relatively high requirements for dimensional accuracy, ordinary die-casting molds cannot produce complex-shaped clutch parts and obtain high dimensional accuracy. A special die-casting mold with higher precision is required for die-casting the clutch during die-casting.

[0003] Currently, cooling pipelines for temperature reduction are provided in die-casting molds. For example, a die-casting mold for producing a clutch housing disclosed in Chinese Patent Publication No. "CN117102463B" includes an upper mold and a lower mold. The upper mold can be embedded inside the lower mold, and a bowl-shaped clutch housing cavity appears at their connection. A feeding channel is opened at the edge of the upper mold, and the feeding channel is communicated with the inside of the cavity. Upper preheating channels and lower preheating channels are respectively opened inside the upper mold and the lower mold. The upper preheating channel and the lower preheating channel are vertically distributed outside the cavity, and the preheating through the upper preheating channel and the lower preheating channel is used to reduce the temperature difference between the molten object and the feeding channel.

[0004] Currently, the die-casting molds for clutches all have cooling pipelines opened inside. Since the cooling pipelines are opened inside the mold, the cooling pipelines cannot be conveniently opened either. Therefore, this cooling method is not convenient for cleaning after long-term cooling, and impurities or scale generated by the cooling water are likely to accumulate in the cooling pipelines and affect the normal flow. Summary of the Utility Model

A number of connecting mechanisms 6 are provided between the cooling assembly 5 and the lower die 2; this die-casting mold can assemble an upper cooling plate 51 and a lower cooling plate 52 into a cooling part, and can be movably inserted into the lower die 2. The entire cooling water channel can not only be conveniently disassembled for cleaning, but also the cooling water channel with different paths can be conveniently changed through the preliminary design, which is convenient for adapting to different workpieces, can effectively avoid impurities such as scale remaining in the cooling water channel, and is also convenient for adaptation.

[0023] In this embodiment, the cooling assembly 5 includes an upper cooling plate 51 and a lower cooling plate 52. The upper cooling plate 51 and the lower cooling plate 52 are symmetrically designed. Corresponding connecting pipes 53 are fixed on one side of the upper cooling plate 51 and the lower cooling plate 52. A cooling pipeline 54 is provided on the contacting side of the upper cooling plate 51 and the lower cooling plate 52. The connecting pipe 53 and the cooling pipeline 54 are semicircular in shape and can become a circular connecting pipe 53 and cooling pipeline 54 after splicing. A fixing mechanism 7 is provided between the upper cooling plate 51 and the lower cooling plate 52.

[0024] Furthermore, the fixing mechanism 7 includes a threaded column 71, and the threaded column 71 is fixed on the four sides of the surface of the lower cooling plate 52. The surface of the upper cooling plate 51 is provided with through holes 72 on the four sides. The threaded column 71 passes through the through holes 72 and is threadedly connected with a nut 73. The threaded column 71 can pass through the through holes 72 and be fixed by the nut 73.

[0025] Furthermore, a circular groove 8 adapted to the nut 73 is formed at the top of the through hole 72. The nut 73 is located inside the circular groove 8 when tightened. The circular groove 8 can hide the nut 73 to prevent the nut 73 from affecting the installation.

[0026] In addition, an annular groove 9 is formed on the contacting side of the upper cooling plate 51 and the lower cooling plate 52, and an annular gasket 10 is embedded in the inner side of the annular groove 9. The annular gaskets 10 can contact each other to perform sealing and prevent cooling water leakage.

[0027] It should be noted that the connecting mechanism 6 includes a connecting plate 61 hinged to the upper cooling plate 51 and hinged to the two sides of the front of the lower cooling plate 52, a hook 62 is fixed on one side of the connecting plate 61, and fixed blocks 63 are fixed on all four sides of the front of the lower mold 2, and a slide groove 64 is opened inside the fixed block 63, and a T-block 65 is slidably connected to the inner side of the slide groove 64, a spring 66 is provided on the inner side of the slide groove 64, and the two sides of the spring 66 respectively conflict with the T-block 65 and the inner side of the slide groove 64, the hook 62 is movably engaged with the T-block 65, and the T-block 65 can cooperate with the hook 62 for limiting, so as to facilitate the clamping of the connecting plate 61.

[0028] In addition, a through groove 11 for moving the T-block 65 is provided on the outer side of the fixed block 63, and a protrusion 12 is fixed on the outer side of the T-block 65 and the protrusion 12 extends to the outside of the slide groove 64 through the through groove 11.

[0029] Working method: When cooling is in progress, the water supply pipeline can be connected through the connecting pipe 53 to cool the lower mold 2. When the cooling device needs to be cleaned or replaced, the staff can use their fingers to move the protrusion 12, and the protrusion 12 drives the T-block 65 to move upward, thereby driving the T-block 65 to disengage from the hook 62, thereby releasing the limit of the connecting plate 61, and then the connecting plate 61 can be rotated to release the limit on the cooling assembly 5. Then the staff will take out the cooling assembly 5 as a whole, and then use a tool to unscrew the nut 73, and then the upper cooling plate 51 and the lower cooling plate 52 can be separated and disassembled. After disassembly, the water channel can be cleaned, and then it can be reinstalled and assembled.
