[0002] Die-casting molds are tools for casting metal parts. They are tools that complete the die-casting process on a special die-casting forging machine. Die-casting materials, die-casting machines, and molds are the three major elements of die-casting production, and none of them can be missing. The so-called die-casting process is to organically and comprehensively utilize these three major elements to stably, rhythmically and efficiently produce qualified castings with good appearance and internal quality and dimensions that meet the requirements of the drawings or agreements, or even high-quality castings. The die-casting mold is one of the important components of the die base.

[0003] However, the current die-casting molds still have some shortcomings. For example, the existing die-casting molds are mostly fixed inside the mold base by fastening bolts, which makes it difficult for the mold base to quickly replace different types of die-casting molds according to usage needs, which affects the processing of the workpiece, resulting in a decrease in the practicality of the die-casting mold and a decrease in the efficiency of use, resulting in certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a die-casting mold and a mold base that are easy to replace. Utility Model Content

The outer dimensions of the block 406 match the outer dimensions of the lower die base 401, and the lower die 407 is connected to the lower die base 401 through the docking block 406. The inner dimensions of the limiting through hole 408 match the outer dimensions of the limiting rod 403, and the limiting rod 403 is embeddedly connected to the lower die 407 through the limiting through hole 408. The limiting cylinder 402 is fixedly installed on both sides of the outer side of the lower die base 401 by fastening bolts, and the limiting rod 403 is installed in the limiting cylinder 402. At the same time, the return spring 404 is used to elastically connect the limiting rod 403 to the limiting cylinder 402. The inner dimensions of the limiting through holes 408 opened on both sides of the mold 407 match the outer dimensions of the limiting rod 403, so that the limiting through holes 408 are used in conjunction with the limiting rod 403 to limit the installation of the lower mold 407 inside the lower mold base 401. At the same time, the docking groove 405 opened inside the lower mold base 401 matches the docking block 406 added to the bottom of the lower mold 407, so that the accuracy and convenience of the installation and docking of the lower mold 407 are further increased by cooperating with the docking block 406, thereby increasing the overall use efficiency of the mold base.

[0022] like Figure 1 and Figure 2As shown in the figure, a limiting component 5 is arranged below the top plate 3. The limiting component 5 includes a hydraulic cylinder 501, an upper die holder 502 and an upper die 503. The front end of the hydraulic cylinder 501 is installed with the upper die holder 502, and the upper die 503 is arranged in the middle of the upper die holder 502. The limiting component 5 further includes a limiting slider 504, a limiting through groove 505 and a limiting vertical rod 506. Limiting sliders 504 are additionally arranged on both sides of the outside of the upper die holder 502. At the same time, a limiting through groove 505 is opened inside the limiting slider 504, and a limiting vertical rod 506 is connected inside the limiting through groove 505. The internal dimension of the limiting through groove 505 matches the external dimension of the limiting vertical rod 506, and the limiting slider 504 is slidably connected with the limiting vertical rod 506 through the limiting through groove 505. The hydraulic cylinder 501 is fixedly installed in the middle of the inside of the top plate 3 through fasteners, and the upper die holder 502 is fixedly installed at the front end of the hydraulic cylinder 501 in cooperation with the fasteners. The operation of the hydraulic cylinder 501 drives the upper die holder 502 to move in position, so that the upper die 503 arranged inside the upper die holder 502 moves in position accordingly. At the same time, the internal dimension of the limiting through groove 505 opened inside the limiting sliders 504 installed on both sides of the outside of the upper die holder 502 matches the external dimension of the limiting vertical rod 506 installed in the middle of the inside of the receiving vertical plate 2. Therefore, the stability of the limiting slider 504 during the movement is increased through the cooperation of the limiting through groove 505 and the limiting vertical rod 506, thereby avoiding the position deviation of the upper die holder 502 during movement, improving the accuracy of die holder docking, and increasing the stability and use efficiency during the use of the die holder.

[0023] A die holder, which is installed with the above-mentioned die-casting die that is convenient to replace.

The operation of the hydraulic cylinder 501 drives the upper mold base 502 to move its position, so that the upper mold 503 set inside the upper mold base 502 moves its position accordingly. At the same time, the internal dimensions of the limiting through grooves 505 opened in the limiting sliders 504 installed on both sides of the outer side of the upper mold base 502 match the external dimensions of the limiting vertical rods 506 installed in the middle end of the receiving vertical plate 2, so that the limiting through grooves 505 are combined with the limiting vertical rods 506 to increase the stability of the limiting slider 504 during movement, thereby avoiding the position of the upper mold base 502 during movement. The offset improves the accuracy of the mold base docking and increases the stability and efficiency of the mold base during use. Then, the limiting cylinder 402 is fixedly installed on both sides of the outer side of the lower mold base 401 by tightening bolts, and the limiting rod 403 is installed into the limiting cylinder 402.
