Description

Technical Field

[0002] In the aluminum alloy wheel manufacturing industry, gravity casting machines are usually used to cast blanks. At present, the gravity casting machine itself does not have a blank removal mechanism. The cast blanks are taken out of the gravity casting machine by manual clamping or by a rack robot after the wheel hub is molded. However, the above two clamping methods have the following defects:

[0003] The problem with manual clamping is that due to the heavy weight of the wheel hub blank, it is difficult for workers to clamp it, and a large clamping force is required, which increases the labor intensity of the workers. At the same time, the temperature of the wheel hub blank is high, and if the workers operate improperly, scalding accidents are very likely to occur, which poses a great safety hazard.

[0004] There are problems with the gripping method of the traveling frame robot. When the traveling frame robot grips, the entire upper template needs to be moved away in the gripping direction, otherwise it is inconvenient for the robot to grip. Therefore, the entire machine structure is complex and the retrieval time is long, which will cause the mold temperature to drop, affecting the quality of the cast hub and the production rhythm. In addition, the human-machine collaboration requirements are high and safety accidents are prone to occur. Summary of the invention

[0047] The working principle of the present invention is as follows:

[0048] When it is necessary to cast an aluminum alloy wheel hub, first, close the molding die 2, and inject aluminum liquid into the mold from the top of the molding die 2 for molding. After molding is completed, the split unit of the lower mold 21 pulls the lower mold outward through the push-pull cylinder 7 to separate, and the wheel hub is exposed. At the same time, the driving cylinder 4a pulls the first connecting shaft 4c and the upper mold upward to complete the mold opening. When the driving cylinder 4a drives the upper mold to open the mold, it also drives the clamping mechanism 5 to move upward a certain distance. Then, the lifting mechanism 3 lifts the wheel hub upward for a certain distance and completely disengages. The clamping cylinder 5b of the clamping mechanism 5 drives the claw 5c to move forward to fix the lower end of the wheel hub, and then the driving cylinder 4a drives the wheel hub to continue to move upward for a certain distance and then stop. At this time, the rotating cylinder 6c of the receiving mechanism 6 works, and drives the receiving plate 6a to rotate to the bottom of the wheel hub through the adjusting column 6f. At this time, the clamping cylinder 5b of the clamping mechanism 5 retracts and places the wheel hub on the receiving plate 6a, and the receiving mechanism 6 rotates out of the work station to complete the material collection. Then, all mechanisms are reset and the operation can be repeated.

When it is necessary to receive the material of the wheel hub, the clamping cylinder 5b of the clamping mechanism 5 drives the claw 5c to move forward to fix the lower end of the wheel hub, and then drives the oil cylinder 4a to drive the wheel hub to continue to move upward for a certain distance and then stop. At this time, the sliding cylinder 8a and the material receiving disc 8b slide to the bottom of the wheel hub, and the clamping cylinder 5b of the clamping mechanism 5 recycles and places the wheel hub on the material receiving disc 6a, and the material receiving mechanism 6 rotates out of the work station to complete the material collection. Then, all mechanisms are reset and the operation is repeated.
