Description

Technical Field

[0001] The utility model relates to the field of automobile die-casting production, in particular to a die-casting demoulding and cleaning device for automobile die-castings. Background Technique

[0002] Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal by using a mold cavity, so that the metal liquid quickly fills the mold cavity under the action of pressure and solidifies under high pressure. Since it is formed under high pressure, the dimensional accuracy and surface finish of die-castings are relatively high, which can meet many applications with high-precision requirements.

[0003] After retrieval, the Chinese patent publication number: CN220216679U discloses a die-casting demoulding and cleaning device for automobile die-castings. Through a first cleaning tank, a second cleaning tank, a spraying part, a water pumping part, a material frame, a driving mechanism, and a fixing frame, this cleaning device can clean automobile die-castings at least twice. Among them, the first cleaning is carried out in the first cleaning tank, and the second cleaning is carried out in the second cleaning tank. When the first cleaning is carried out, the material frame loaded with the die-castings to be cleaned is placed in the first cleaning tank, and the water pumping part pumps the liquid in the second cleaning tank to the first cleaning tank, and the spraying part conducts a primary cleaning on the die-castings to be cleaned; after the first cleaning is completed, the driving mechanism drives the material frame to rise, then moves along the fixing frame to above the second cleaning tank and then descends into the second cleaning tank, and the spraying part pumps water from the clean water bucket to conduct a secondary cleaning on the die-castings. This cleaning device realizes the soaking and multiple cleanings of die-castings at the same time, increases the utilization rate of cleaning water, and reduces the waste of water resources.

[0004] However, during the use of the above device, since the die-castings to be cleaned need to be stored in the material frame for cleaning, and the material frame is easy to block the side walls of the die-castings, and the die-castings are fixed during cleaning, it makes it difficult for the water sprayed by the spraying part to wash the outer walls of the die-castings comprehensively and evenly. At the same time, the impurities washed off from the die-castings will fall into the material frame, resulting in the impurities in the material frame adhering to the cleaned die-castings again, reducing the use effect of the die-casting cleaning device.

The bottom of the water tank 31 is fixedly installed at the top right end of the bottom plate 1, and the tank cover 32 is fixedly installed on the top of the water tank 31, which plays a protective role for the clean water in the water tank 31 to prevent the clean water in the water tank 31 from being polluted. The floating plate 33 is slidably connected to the inside of the water tank 31. The floating plate 33 has a buoyancy effect and can rise and fall according to the water level in the water tank 31. The indicating rod 34 is fixedly installed on the top of the floating plate 33. When the floating plate 33 rises and falls, it can drive the indicating rod 34 to move vertically. The indicating rod 34 penetrates and is slidably connected to the inner wall of the tank cover 32. When the indicating rod 34 moves vertically, the length of the indicating rod 34 exposed outside the tank cover 32 will change, so as to remind the staff.

Two groups of springs 37 are symmetrically distributed. Through the elastic force of the spring 37, the plug rod 38 always maintains the clamping effect with the clamping groove without external force, so as to limit the protective cover 36 and keep the water filling pipe 35 in a closed state all the time. The outer wall of the plug rod 38 is slidably connected to the right inner wall of the water filling pipe 35. Through the sliding effect of the plug rod 38, the plug rod 38 is clamped or unclamped with the clamping groove, so as to limit or release the limit of the protective cover 36.
