Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to a die casting mould fixing device. Background Art

[0002] Die casting mold is a tool for casting metal parts, a tool that completes the die casting process on a special die casting forging machine. The basic process of die casting is: the molten metal is first cast and filled into the mold cavity at a low speed or high speed. The mold has a movable cavity surface, which is pressurized and forged with the cooling process of the molten metal, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank are significantly improved. When processing the mold, a fixture needs to be used to fix the mold before processing.

[0003] Chinese patent publication number CN214321749U discloses a die-casting mold fixing device, including a bracket, a support plate and a fixing block, wherein the bracket is fixedly connected with a support plate inside, and the bracket is fixedly connected with fixing blocks on both sides, and a slide groove is embedded above the fixing block, and an electric push rod is fixedly connected inside the slide groove. Although the device can be connected to the slider by embedding a slide groove above the fixing block and arranging an electric push rod inside the slide groove, so that the clamping block arranged at one end of the connecting rod is inclined to clamp the die-casting mold, it can be adjusted according to the specifications of the mold, and has high versatility. By embedding a placement groove above the support plate, and arranging a hydraulic cylinder inside the placement groove, the mold is pushed up by a push plate arranged above the telescopic rod, so that the uncooled mold is avoided from being manually taken, and the danger is reduced. However, most common mold fixing devices are not convenient for adapting to molds of different sizes, and are more troublesome to use. A few fixing devices that can adjust the size usually have a more complicated adjustment method, so they need to be improved. Utility Model Content

[0027] See also Figure 2-5 The surface of the guide block 3 is slidably connected with a connecting block 9, there are two groups of connecting blocks 9, and there are two groups of sliders 11. Threads are provided inside the two groups of sliders 11 to facilitate engagement with the threads A7 and B8. The threads inside one group of sliders 11 are engaged with the threads A7, and the threads inside the other group of sliders 11 are engaged with the threads B8. The threads A7 and B8 have opposite rotation directions. The anti-adjustment rod 6 drives the threads A7 and B8 to rotate while driving the sliders 11 to move toward each other, thereby facilitating adjustment of the spacing between the splints 10. The splint 10 is fixedly installed on the top surface of the connecting block 9, and the slider 11 is fixedly installed on the bottom surface of the connecting block 9.

[0028] Embodiment 2

[0029] See also Figure 4-5A circular groove 13 is provided inside the splint 10, and a slide bar 14 is fixedly installed inside the circular groove 13. A tension spring 15 is sleeved on the surface of the slide bar 14, and a sleeve 16 is slidably connected to the surface of the slide bar 14. A positioning plate 17 is fixedly installed at one end of the sleeve 16, and one end of the tension spring 15 is fixedly connected to the surface of the sleeve 16, and the other end of the tension spring 15 is fixedly connected to the inside of the circular groove 13, so that the sleeve 16 can be reset when the tension spring 15 automatically recovers, so that the sleeve 16 drives the positioning plate 17 to move, and then the positioning plate 17 clamps and fixes the mold, and a rubber pad 18 is fixedly installed on the surface of the positioning plate 17, so as to increase the friction between the mold and the positioning plate 17 and further improve the fixing effect of the positioning plate 17.

[0030] Working principle: When in use, first place the mold to be fixed on the support table 2, and then rotate the turntable 12. The turntable 12 drives the adjusting rod 6 to rotate, and at the same time, the threads A7 and B8 at both ends of the adjusting rod 6 also start to rotate. Since the slider 11 is engaged with the threads A7 and B8, the adjusting rod 6 drives the slider 11 to move toward each other, and at the same time, the slider 11 drives the connecting block 9 to move, and the connecting block 9 slides on the surface of the guide block 3. At the same time, the connecting block 9 drives the splint 10 to move until the side of the splint 10 is in contact with the surface of the mold. At this time, stop rotating the turntable 12, and the splint 10 can clamp the mold. When the mold needs to be replaced, rotate the turntable 12 in the opposite direction, and the turntable 12 drives the adjusting rod 6 to rotate in the opposite direction. The adjusting rod 6 then drives the threads A7 and B8 to rotate in the opposite direction. At this time, the threads A7 and B 8 drives the slider 11 to move toward the two ends of the adjusting rod 6. At the same time, the slider 11 drives the connecting block 9 to slide on the surface of the guide block 3. The connecting block 9 drives the clamping plate 10 to gradually move away from the mold surface. Then the mold can be removed and replaced. When fixing the mold, pull the positioning plate 17 outward. The positioning plate 17 drives the sleeve 16 to move outward. The sleeve 16 then drives the tension spring 15 to move outward. At the same time, the sleeve 16 slides on the surface of the slide bar 14 until the positioning plate 17 is matched with the size of the mold. At this time, place the mold on the support table 2, and then release the hand that pulls the positioning plate 17. At this time, the tension spring 15 loses the external force restriction. Due to its own tension, it drives the sleeve 16 to move into the circular groove 13 until the tension spring 15 recovers. At this time, the positioning plate 17 is in contact with the mold surface and fixes the mold between the positioning plate 17 and the support table 2.
