[0002] A zinc-aluminum alloy die-casting machine is a die-casting equipment specifically designed for zinc and aluminum alloy materials. It uses high pressure to press molten zinc or aluminum alloy into a mold cavity, quickly forming it into metal parts with complex shapes and high precision. The die-casting machine mold can be replaced and installed using a replacement device.

[0003] When using existing mold changing devices, the mold is moved to designated positions at both ends of the die-casting machine using a hoisting device. Then, the clamping device at the inner edge of the die-casting machine is pushed so that it inserts into both sides of the mold, thus completing the quick mold change. However, after the mold has been moved and used for a long time in the die-casting machine, the connection between the mold and the clamping device is prone to loosening, which affects the normal use of the mold. Therefore, it is necessary to propose an auxiliary and stable quick changing device to stabilize the connection between the clamping device and the mold. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figures 1-4 As shown, this utility model is a quick-change device for zinc-aluminum alloy die-casting machine molds, comprising: Quick-change assembly, which includes a set of clamps 13; The quick-change assembly also includes a groove 11, a slide bar 12, and a connecting line 14; the groove 11 is a set and is opened at the inner edge of the die-casting machine; the slide bar 12 is slidably connected to the inner side of the groove 11; the mold clamp 13 is fixed to the outer end of the slide bar 12; and the connecting line 14 is fixed to the center of one side of the outer end of the mold clamp 13. The groove 11 is used for connecting the slide rod 12, the slide rod 12 is used for connecting the mold clamp 13, the mold clamp 13 is used to limit the mold to be installed, and the connecting line 14 is used to connect the mold clamp 13 to external equipment.

[0018] The stabilizing assembly includes a crossbar 21, a telescopic rod 22, a connecting plate 23, and a positioning ring 24. The crossbar 21 is fixed to the center of the outer ends of the two middle clamping devices 13. The telescopic rod 22 is fixed to the opposite sides of the outer ends of the upper and lower clamping devices 13. The opposite ends of the connecting plate 23 are rotatably connected to the output end surface of the telescopic rod 22, and the opposite ends are inserted into the outer ends of the crossbar 21. The positioning ring 24 is threaded to the outer end of the crossbar 21 and is located outside the connecting plate 23. The crossbar 21 is used to connect the connecting plate 23, the telescopic rod 22 is used to connect the bottom of the connecting plate 23, the connecting plate 23 is used to connect the two middle clamping devices 13 with the upper and lower clamping devices 13, and the positioning ring 24 limits the position of the connecting plate 23 after it is sleeved with the crossbar 21.

[0019] The connecting plate 23 has a connecting hole 25 at the insertion point with the crossbar 21. A fixing ring 26 is fixedly connected to the inner surface of the crossbar 21 and is in close contact with the inner surface of the connecting plate 23. A lower plate 27 is fixedly connected to the bottom outer side of the positioning ring 24. The surface of the lower plate 27 is provided with a insertion hole 28, and a positioning rod 29 is threadedly connected to the inner side of the insertion hole 28. One end of the positioning rod 29 extends to the inside of the die-casting machine, and the die-casting machine has a positioning groove 291 at the connection with the positioning rod 29. The connecting hole 25 is used to connect the opposite end of the connecting plate 23 to the crossbar 21. The fixing ring 26 and the positioning ring 24 are used together to limit the connection of the connected plate 23 after it is sleeved. The lower plate 27 is used to open the insertion hole 28. The insertion hole 28 is used for the insertion and rotation of the positioning rod 29. The positioning groove 291 is used to connect the positioning rod 29 to the die casting machine. Pushing the mold clamp 13 will limit the mold. At this time, the mold clamp 13 will drive the positioning rod 29 to move to correspond with the positioning groove 291. Rotating the positioning rod 29 will cause the positioning rod 29 to rotate and insert into the positioning groove 291, thereby limiting the movement of the mold clamp 13 and the connecting plate 23.

[0020] Working principle: When the component is not in use, the clamping device 13 is located at the inner edge of the die-casting machine. When the component is in use, the mold is moved to the designated position inside the die-casting machine by the hoisting device. The operator uses the clamping device 13 to insert it into both sides of the mold. At this time, the operator rotates the upper and lower connecting plates 23 by hand, so that the opposite ends of the connecting plates 23 are tightly attached to the upper crossbar 21. Pushing the connecting plates 23 pushes the telescopic rod 22 to retract, so that the connecting plates 23, through the telescopic rod 22, drive the connecting hole 25 to engage with the crossbar 21, and rotate the positioning ring 24 to engage. At the outer end of the crossbar 21, the positioning ring 24 limits the connection plate 23 after it is snapped in. At this time, the insertion hole 28 corresponds to the positioning groove 291. The positioning rod 29 is rotated and inserted into the insertion hole 28, and the inner end of the positioning rod 29 is rotated and inserted into the positioning groove 291. This causes the positioning rod 29 to be connected to the insertion hole 28 and the positioning groove 291 through the thread. This allows the positioning rod 29 and the positioning ring 24 to limit the connection plate 23 and the clamping device 13 after they are snapped in, thus connecting the clamping devices 13 together and further stabilizing the connection between the clamping devices 13.

[0021] Please see Figures 1-2 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes: Connection components; The connecting assembly includes a fixing rod 31, a vertical rod 32, and a pin 33; the fixing rod 31 is fixed to the center of the bottom end of the upper middle clamping device 13, the vertical rod 32 is fixed to the center of the top end of the lower middle clamping device 13, the top end of the vertical rod 32 is inserted into the bottom end of the fixing rod 31, and the pin 33 passes through the insertion point of the vertical rod 32 and the fixing rod 31. The fixing rod 31 and the vertical rod 32 are used together to connect the two middle clamping devices 13. The pin rod 33 is used to limit the fixing rod 31 and the vertical rod 32 during insertion, so that the two middle clamping devices 13 are connected together.

[0022] The fixing rod 31 has a slot 34 at the insertion point with the vertical rod 32, and the fixing rod 31 and the vertical rod 32 have insertion holes 35 at the passage points with the pin rod 33. The insertion holes 35 are threadedly connected to the pin rod 33. The slot 34 is used for the connection between the vertical rod 32 and the fixed rod 31. The insertion hole 35 is used for the insertion and rotation of the pin rod 33. The two middle clamping devices 13 are pushed one by one. The lower clamping device 13 drives the vertical rod 32 to be inserted into the slot 34, so that the insertion holes 35 on the surfaces of the two are aligned. The pin rod 33 is rotated and inserted into the insertion hole 35, so that the fixed rod 31 and the vertical rod 32 are connected together, thereby limiting the two middle clamping devices 13 and further stabilizing the connection of the clamping devices 13 on the same side.

[0023] Working principle: When the component is not in use, the operator does not push the clamping device 13. When the component is in use, push the two middle clamping devices 13 one by one. When pushing the lower clamping device 13, the lower clamping device 13 drives the vertical rod 32 to insert into the slot 34, so that the insertion holes 35 on the surface of the two are aligned. By hand, rotate the pin rod 33 to insert it into the insertion hole 35. The pin rod 33 is rotated and connected to the inside of the insertion hole 35 through the thread, so that the fixing rod 31 is connected to the vertical rod 32, thereby limiting the two middle clamping devices 13, which facilitates the subsequent connection of the connecting plate 23 and the horizontal rod 21.
