[0002] Die casting machines are machines used for pressure casting, including both hot and cold chamber types; they are further divided into vertical and horizontal types. Under pressure, the die casting machine injects molten metal into a mold to cool and solidify. After the mold is opened, a solid metal casting can be obtained. It was initially used for die casting lead type. When using die casting molds, they need to be replaced and adjusted according to the different shapes of the die castings.

[0003] A Chinese utility model patent (publication number: CN222429230U) discloses a detachable die-casting mold for a die-casting machine, comprising a base; a die-casting mold body is inserted into the top of the base near the middle position, and the base and the die-casting mold body are slidably connected; a detachable assembly / disassembly mechanism is provided between the base and the die-casting mold body; the detachable assembly / disassembly mechanism includes a first fixing block, which is located on the left and right sides of the top of the base; through the design of the detachable assembly / disassembly mechanism, the function of easy disassembly is realized, solving the problem that existing die-casting machines do not have components that facilitate the disassembly of the die-casting mold. Since the shape and size of the die-casting needs to be adjusted as needed during die-casting production, it is necessary to replace the die-casting mold with different specifications. However, existing die-casting machines are difficult and not easy to operate when replacing the die-casting mold.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned easy-to-disassemble die-casting mold for die-casting machines: In the above technical solution, the third insert block is disengaged from the second slot by the automatic rebound and contraction of the return spring. The return spring will gradually weaken its elasticity due to fatigue of the spring material when used at high frequency. When the bolt is disengaged from the threaded hole, the third insert block has difficulty disengaging from the second slot. Therefore, an easy-to-disassemble mold for die-casting machines is proposed. Utility Model Content

[0005] This utility model proposes a disassembly-friendly mold for die-casting machines, which solves the problem in related technologies where the third insert block is difficult to disengage from the second slot when the bolt is disengaged from the threaded hole.

[0006] The technical solution of this utility model is as follows: A disassembly-friendly mold for a die-casting machine, comprising: The base and the mold body detachably connected to the top of the base, both having limit blocks fixedly installed at the bottom of the mold body; A limiting plate is slidably connected to both sides of the inner wall of the base.

A push-pull assembly 5 is provided on the bottom inner wall of base 1, and one end of the push-pull assembly 5 is fixedly connected to the limiting plate 4. Power assembly 6 is installed on the top inner wall of base 1. Oil pipes 7 are fixedly installed on the outer walls of power assembly 6. One end of oil pipe 7 passes through base 1 and is connected to one end of push-pull assembly 5. Each base 1 has a limiting groove 10 on its top, and the limiting block 3 is inserted into the limiting groove 10. A threaded rod 11 is threaded through one side of the limiting plate 4, and a connecting block 12 is fixedly connected to one end of the threaded rod 11. A threaded groove 13 is opened on one side of the limiting block 3, and the threaded rod 11 and the threaded groove 13 are threadedly connected. A slot 14 is provided on one side of the limiting block 3, and a block 15 is fixedly installed on one side of the limiting plate 4. The block 15 and the slot 14 are engaged. When disassembling the mold body 2, rotating the connecting block 12 drives the threaded rod 11 to rotate until the threaded rod 11 disengages from the threaded groove 13. The power component 6 moves downward, allowing the hydraulic oil inside the push-pull component 5 to enter the power component 6 through the oil pipe 7. At this time, the push-pull component 5 drives the limiting plate 4 to move, and the limiting plate 4 drives the locking block 15 to disengage from the locking groove 14. Moving the mold body 2 upward causes the limiting block 3 to separate from the limiting groove 10, thus completing the convenient disassembly of the mold body 2. Conversely, moving it downward facilitates the installation of the mold body 2.

The connecting cylinder 61 is located on the top inner wall of the base 1. The cylinder 62 is located at the bottom end of the connecting cylinder 61. The output end of the cylinder 62 passes through the connecting cylinder 61 and is fixedly connected to the piston 63. The oil pipes 7 are all fixedly installed on the outer wall of the connecting cylinder 61. The output end of cylinder 62 drives piston 63 to move downward, so that the hydraulic oil inside the fixed cylinder 51 enters the connecting cylinder 61 through the oil pipe 7. At this time, piston 53 and rod 52 move away from the limiting plate 4. Rod 52 drives the limiting plate 4 to move. The limiting plate 4 drives the locking block 15 to smoothly disengage from the slot 14. The fixed cylinder 51, oil pipe 7 and connecting cylinder 61 are all filled with hydraulic oil.

[0023] Specifically, mounting ears 8 are fixedly installed on both sides of the base 1, and mounting grooves 9 are opened through the top of the mounting ears 8; The mounting ears 8 and mounting slots 9 facilitate the installation of the base 1 on the worktable of the die-casting equipment.

[0024] Specifically, the inner wall of the base 1 has grooves 16 on both sides, and the limiting plate 4 is slidably connected to the grooves 16. When the limiting plate 4 moves, it slides through the slide groove 16 to guide the movement of the limiting plate 4.
