Description

Technical Field

[0001] The utility model relates to a quick replacement device for a die-casting mold, belonging to the technical field of die-casting molds. Background Art

[0002] A die-casting mold is a tool used to manufacture metal castings, primarily during the high-pressure casting process. Its basic structure, consisting of a cavity, core, cooling channels, and exhaust system, enables the precise formation of complex metal parts. Die-casting molds are typically made of heat- and wear-resistant alloy steel to withstand high temperatures and high pressures. By injecting molten metal into the mold cavity at high pressure and rapidly cooling it to form the part, die-casting molds offer high production efficiency, excellent dimensional accuracy, and a smooth surface finish, making them widely used in the production of parts for the automotive, electronics, and machinery industries.

[0003] In the prior art, the lower mold of the die-casting mold needs to be disassembled by bolt engagement. During the disassembly process, there is a risk of damaging the parts of the die-casting mold, causing significant damage to the assembly surfaces and dimensions of the parts. In addition, disassembly is cumbersome and inconvenient. If the lower mold is inconvenient to disassemble, regular cleaning and maintenance will become more difficult, which may cause the mold to accumulate metal residues, oxidize or corrode, affecting the service life of the mold and the quality of the casting. At the same time, during the production process, if the mold needs to be replaced or the mold design needs to be adjusted, the inconvenience of disassembly will extend the downtime, reduce production efficiency, and affect the production plan.

[0004] To this end, a device for quickly replacing a die-casting mold is proposed. Utility Model Content

The quick-release assembly 4 includes a quick-release box 401, the quick-release box 401 is fixedly connected to the left and right sides of the top of the base 1, a return spring 410 is provided on the outside of the inner cavity of the quick-release box 401, a movable block 412 is fixedly connected to the inside of the return spring 410, a movable plate 405 is fixedly connected to the top of the movable block 412, a transmission rod 402 is fixedly connected to the inside of the transmission rod 402, a fixed plate 403 is fixedly connected to the inside of the fixed plate 403, and a plurality of insertion rods 404 are fixedly connected to the inside of the fixed plate 403, and the insertion rods 404 are inserted into the sockets 11.

[0026] By pulling the movable plate 405 outward, the movable block 412 is driven to move outward, and the movable block 412 squeezes the return spring 410 and deforms due to the influence of the force. At the same time, the movable block 412 drives the transmission rod 402 to move outward, and the transmission rod 402 drives the fixed plate 403 to move outward, and the fixed plate 403 drives the insertion rod 404 to leave the insertion hole 11, thereby releasing the limit on the lower mold 3. The staff pulls the lower mold 3 upward to make it leave the holder 2, and then completes its quick disassembly, thereby improving the efficiency of mold replacement.

[0027] Example 2

[0028] In one embodiment, the top of the quick-release box 401 is fixedly connected to a connecting plate 408, the inner surface of the connecting plate 408 is threadedly connected to an adjusting bolt 409, the inner side of the adjusting bolt 409 is fixedly connected to a limiting ring 407, a slide groove 411 is provided at the bottom of the inner cavity of the quick-release box 401, the bottom of the movable block 412 is fixedly connected to a slider 413, and the bottom of the slider 413 is slidably connected in the slide groove 411, a guide groove 406 is provided at the top of the quick-release box 401, the outer wall of the movable plate 405 is fitted with the guide groove 406, the top of the base 1 is fixedly connected to a fixing frame 6, the top of the fixing frame 6 is provided with a cylinder 10, the bottom of the cylinder 10 is provided with a mounting plate 9, the bottom of the mounting plate 9 is provided with an upper mold 8, both sides of the top of the base 1 are fixedly connected to vertical plates 5, the left and right sides of the mounting plate 9 are fixedly connected to slide plates 7, and the outer side of the slide plate 7 is slidably connected to the vertical plate 5.

[0029] By rotating the adjusting bolt 409 to drive the limiting ring 407 to move inward and release it from the movable plate 405, it can be limited to prevent it from loosening and affecting the fixing effect on the lower mold 3. By setting the slider 413 and the slide groove 411, the movable block 412 can be guided to avoid its deviation during movement, thereby improving its stability during movement. By setting the slide plate 7 and the vertical plate 5, the mounting plate 9 can be limited to improve its stability during the up and down operation and avoid deviation.

[0030] When the utility model is working: when the lower mold 3 needs to be disassembled, first, the movable block 412 is moved outward by pulling the movable plate 405 outward, and the movable block 412 squeezes the return spring 410 and is deformed due to the influence of the force. At the same time, the movable block 412 drives the transmission rod 402 to move outward, and the transmission rod 402 drives the fixed plate 403 to move outward, and the fixed plate 403 drives the insertion rod 404 to leave the insertion hole 11, thereby releasing the limit of the lower mold 3. The staff pulls the lower mold 3 upward to make it leave the card seat 2, and the rapid disassembly of it can be completed, thereby improving the efficiency of mold replacement. When the lower mold 3 needs to be installed, first, the movable plate 405 is pulled outward to move the movable block 412 outward, and the movable block 412 squeezes the return spring 410 and is deformed due to the influence of the force. At the same time, the movable block 412 drives the transmission rod 402 to move outward, the transmission rod 402 drives the fixed plate 403 to move outward, and the fixed plate 403 drives the insertion rod 404 to move outward. Then, the lower mold 3 is clamped in the holder 2, and then the movable plate 405 is released. At this time, the return spring 410 is deformed again due to the influence of the loss of force, and drives the movable block 412 to quickly bounce inward. The movable block 412 drives the insertion rod 404 to move inward through the transmission rod 402 and the fixed plate 403 and is inserted into the insertion hole 11, limiting the lower mold 3, and then completing the rapid installation of the lower mold 3. Finally, by rotating the adjusting bolt 409, the limiting ring 407 is driven to move inward and released from the movable plate 405, which can be limited to prevent it from loosening and affecting the fixing effect of the lower mold 3.
