Technical Field
[0001] The utility model relates to the technical field of die-casting molds, in particular to an aluminum die-casting mold that is easy to demould. Background Art
[0002] The die-casting mold is a tool used to cast metal parts. The die-casting process is mainly completed 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 or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, which not only eliminates the shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state.
[0003] In the existing die-casting of aluminum, after the aluminum die-casting is formed, it is inconvenient for the device to demould the formed mold, so the formed aluminum alloy sticks to the surface wall of the mold and cannot be quickly removed, which affects the die-casting efficiency of the device and reduces work efficiency. Utility Model Content

[0006] Preferably, a support frame is fixedly installed on the top of the workbench, a second hole is opened on the top of the support frame, and a second hydraulic cylinder is fixedly installed on the top of the support frame.

[0009] Preferably, a hose is fixedly connected to one side of the outer wall of the storage box, a water pump is arranged on one side of the outer wall of the storage box, and a hole three is opened on the outer wall of the support frame.
[0010] Preferably, a rotating rod is movably inserted into the inner wall of the hole three, a stepping motor is arranged on one side of the outer wall of the rotating rod, and a fixing block is fixedly sleeved on the outer wall of the rotating rod.
[0011] Preferably, a fixing ring is arranged on the top of the fixing block, and a nozzle is arranged on the inner surface wall of the fixing ring.
[0012] Compared with the prior art, the advantages and positive effects of the utility model are:
[0013] 1. In the utility model, the upper mold is lowered and closed with the lower mold by the operation of the second hydraulic cylinder. At the same time, the two guide rods ensure the stability of the mold position, improve production efficiency, extend the service life of the mold, optimize operation and maintenance, and improve production safety. Secondly, the casting is formed by the operation of the first hydraulic cylinder to drive the fixed plate upward to eject the casting, so that the die-casting can be demolded from the mold more quickly, thereby improving the efficiency of the entire die-casting process, allowing the die-casting to be demolded quickly, reducing the waiting time in the production process, and thus improving production efficiency.
[0014] 2. In the utility model, the angle of the nozzle is adjusted by the operation of the stepper motor to make it parallel to the mold. At this time, the water pump operates to extract the lubricating oil in the storage box and spray the mold, which can reduce the friction between the mold and the casting and make the casting easier to separate from the mold. It can ensure that the inside of the mold can be evenly lubricated in each die-casting cycle, thereby improving the demoulding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The effect achieved by the entire embodiment 2 is that when the device is used normally, first, the controller 17 is linearly connected to the stepper motor 23, and the rotation of the stepper motor 23 is controlled by the controller 17, thereby controlling the angle of the nozzle 26, first making the nozzle 26 horizontal, and then the water pump 20 is connected to the hose 19, the hose 19 is fixedly connected to the storage box 18, and the hose 19 is fixedly connected to the nozzle 26, and the lubricating oil can be sprayed autonomously to spray the mold, which helps the casting to be demolded smoothly, avoids damage to the casting during the demolding process, such as scratches, deformation, etc., maintains the integrity and accuracy of the casting surface, and improves product quality.
[0027] Among them, hydraulic cylinder 1 5, hydraulic cylinder 2 12, controller 17, water pump 20 and stepper motor 23 are all existing technologies, and their components and operating principles are all public technologies, so no excessive explanation is given here.
[0028] Working principle: First, when the device is in normal use, a controller 17 is fixedly installed on the top of the workbench 2. The controller 17 is linearly connected to the stepper motor 23, and the stepper motor 23 is connected to the rotating rod 22. The outer wall of the rotating rod 22 is fixedly sleeved with a fixed block 24. The fixing ring 25 on the top of the fixing block 24 is fixed by screws. The fixing ring 25 fixes the nozzle 26 to the fixing block 24. The controller 17 controls the angle of each operation of the stepper motor 23. The operation of the stepper motor 23 can drive the rotating rod 22 to rotate, thereby driving the fixing block 24 to rotate. The angle of the nozzle 26 is adjusted by the speed and angle controlled by the motor 23. The nozzle 26 is first horizontally arranged, and the nozzle 26 is fixedly connected to the hose 19, the hose 19 is fixedly connected to the storage box 18, and is connected to the water pump 20. At this time, the water pump 20 operates to extract the lubricating oil in the storage box 18, and sprays the lubricating oil to the inside of the lower mold 8 through the hose 19. Finally, it is rotated to be vertical. Secondly, a hydraulic cylinder 12 is fixedly installed on the top of the support frame 10, and a piston rod 13 is arranged at the output end of the hydraulic cylinder 12. A connecting rod 13 is fixedly installed at the bottom of the piston rod 13. The connecting plate 14 is fixedly connected to the upper mold 15, and two guide rods 16 pass through the connecting plate 14 and are placed between the support frame 10 and the workbench 2. When the hydraulic cylinder 12 is running, the piston rod 13 is driven to extend and retract, thereby driving the upper mold 15 to descend and fit with the lower mold 8. At the same time, the two guide rods 16 ensure that the relative positions of the two molds are stable during the mold closing and mold opening processes, thereby ensuring the dimensional accuracy and shape integrity of the die-casting product. Secondly, the heated aluminum alloy is injected through the injection port 9 on one side of the outer wall of the lower mold 8, and the aluminum alloy is formed in the mold. Secondly, the top of the support plate 4 A hydraulic cylinder 5 is fixedly installed, and a piston rod 6 is arranged at the output end of the hydraulic cylinder 5. A fixing plate 7 is fixedly installed on the top of the piston rod 6. The fixing plate 7 is embedded in the bottom of the inner wall of the lower mold 8. When the hydraulic cylinder 5 is running, the piston rod 6 is driven to extend and retract, thereby driving the fixing plate 7 to rise and push out the formed model, which is helpful to improve the automation degree of the production line, and can also reduce the labor cost and the influence of human factors on product quality. At the same time, the lubricating oil sprayed in the early stage can form a protective film on the surface of the mold, reduce the friction between the metals, and reduce the wear of the mold due to long-term use.
