Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy processing, in particular to an aluminum alloy die-casting precision molding device. Background Art

[0002] Aluminum alloy die-casting is the process of injecting liquid aluminum alloy into the cavity of a precision metal mold at high speed under high pressure, so that the aluminum alloy quickly cools and solidifies under pressure to form a casting of the desired shape. Depending on the die-casting machine, aluminum alloy die-casting is divided into two basic methods: cold chamber die-casting and hot chamber die-casting.

[0003] At present, the molten aluminum alloy is easy to slide off the surface of the crucible and drip on the surface of the base during the process of pouring into the mold. After a period of processing and production, the molten aluminum accumulated on the surface of the base will be fixed on the base due to temperature cooling, which is difficult to clean, increasing the maintenance cost of the equipment. Moreover, since the molten aluminum alloy drips on the base, it takes extra time to clean it, which not only increases the production cycle, but also reduces production efficiency. At present, the staff often needs to spray the mold cavity surface of the mold with a release agent before die-casting, but most of the spraying is done manually, and the local release agent on the mold surface is insufficient, which can easily lead to sticking of the mold or scratching of the surface of the parts, and the demolding effect is poor.

After the staff turns on the second motor 121, the output shaft of the second motor 121 drives the second threaded rod 122 to rotate, thereby making the second threaded sleeves 123 on the left and right sides move in opposite directions. When the staff controls the rotation direction of the output shaft of the second motor 121, the push rod 124 can push the movable plate 13 out, so that the nozzle 16 can move between the die-casting mold 2 and the aluminum alloy die-casting equipment on the surface of the mounting frame 3, so that the nozzle 16 can evenly spray the release agent on the surface of the die-casting mold 2 and the aluminum alloy die-casting equipment.

[0022] Working principle: When the staff performs aluminum alloy die-casting processing, first the staff controls the mechanical arm to clamp the crucible and pour the aluminum alloy melt into the interior of the die-casting mold 2. After the aluminum alloy melt is poured in, a small amount of aluminum alloy melt will drip on the front side of the top of the base body 1. At this time, the staff controls the aluminum alloy die-casting equipment above the mounting frame 3 to descend, and uses high pressure to inject the liquid aluminum alloy into the precision mold cavity at high speed, so that the aluminum alloy is quickly cooled and solidified under pressure. At the same time, when the aluminum alloy melt dripping on the top of the base body 1 is cooled, the staff can turn on the first motor 51 and the small cylinder 93 to flip the cleaning scraper 10 so that the cleaning scraper 10 is attached to the surface of the base body 1, and the movable rod 94 drives the movable frame 8 to move slowly to the right. As the cleaning scraper 10 moves, the aluminum alloy melt solidified on the surface of the base body 1 is pushed to the right by the cleaning scraper 10, and finally pushed into the interior of the right collection box 18. When the die-casting mold After the aluminum alloy melt inside the mold 2 is cooled and formed, the staff controls the aluminum alloy die-casting equipment above the mounting frame 3 to make the die-casting equipment leave the die-casting mold 2, and the staff can take out the aluminum alloy product cooled and formed inside the die-casting mold 2. At this time, the staff controls the second motor 121 to open, so that the nozzle 16 moves to between the die-casting mold 2 and the aluminum alloy die-casting equipment. At this time, the staff injects the release agent into the inside of the connecting hose 15, so that the nozzle 16 sprays the release agent. At this time, the staff controls the rotation direction of the output shaft of the second motor 121, so that the nozzle 16 moves back and forth between the die-casting mold 2 and the aluminum alloy die-casting equipment, and evenly sprays the release agent on their surfaces. After the spraying is completed, the staff controls the second motor 121 again, so that the movable plate 13 moves back to the inside of the mounting plate 11 again, and then the staff can continue to pour the aluminum alloy melt into the inside of the die-casting mold 2 to perform subsequent aluminum alloy die-casting operations.
