When the formed metal workpiece needs to be taken out from the mold cylinder 1, the supporting and unloading device is moved into the mold cylinder 1 by the moving device connected to the supporting and unloading device, and then the formed metal workpiece is supported and clamped by the supporting and unloading device. Then, the supporting and unloading device is moved in a direction away from the mold cylinder 1 by the corresponding moving device, so that the formed metal workpiece can be taken out from the mold cylinder 1, thereby facilitating the unloading of the formed metal workpiece.

[0018] The cam 32 is provided on one side of the screw 31 to drive the cam 32 to rotate. The cam 32 is provided on both sides of the screw 31 to drive the cam 32 to rotate.

By driving the screw 31 to rotate with the adjusting motor 32, the connecting seat 34 that is mounted on the outer periphery of the screw 31 and threadedly matched with the screw 31 can be moved along the direction of the screw 31 under the guidance of the guide rod 33. In this way, the moving devices on both sides can respectively drive the feed hopper 2 and the top support and unloading device on both sides to move in the direction close to or away from the casting cylinder 1, wherein the feed hopper 2 can adopt the structure produced in the prior art.

[0019] In this embodiment, the specific structure of the supporting and unloading device includes a connecting shaft 41, the connecting shaft 41 and the center line of the mold cylinder 1 are located on the same axis, the connecting shaft 41 is located at one end close to the mold cylinder 1 and is fixed with a symmetrical fixed sleeve 42, the connecting shaft 41 is located at one end away from the mold cylinder 1 and is covered with a movable sleeve 43, a supporting rod 44 is provided on the outside of the connecting shaft 41, a first connecting rod 45 and a second connecting rod 46 are provided between the supporting rod 44 and the fixed sleeve 42 and the movable sleeve 43 respectively, one end of the first connecting rod 45 is rotatably connected to the supporting rod 44, and the other end is rotatably connected to the fixed sleeve 42, the second connecting rod 46 is rotatably connected to the supporting rod 44, and the other end is rotatably connected to the movable sleeve 43, the connecting shaft 41 is located at the end away from the mold cylinder 1 and is provided with a driving The cylinder 47 and the driving cylinder 47 are used to drive the movable sleeve 43 to move. When the formed metal workpiece needs to be taken out from the mold tube 1, the connecting shaft 41 is first moved into the mold tube 1 by the corresponding moving device, and then the output end of the driving cylinder 47 is ejected to move the movable sleeve 43 toward the fixed sleeve 42, thereby pushing the first connecting rod 45 and the second connecting rod 46 to rotate, so as to lift the supporting rod 44 so that the supporting rod 44 can be tightly pressed against the inside of the metal workpiece. In this way, the friction force generated by the contact between the supporting rod 44 and the metal workpiece can complete the clamping of the metal workpiece, and then the supporting unloading device is moved in the direction away from the mold tube 1 by the corresponding moving device, so that the formed metal workpiece can be taken out of the mold tube 1.

The output end of the driving motor 84 is fixed with an active transmission wheel 85. A transmission belt 86 is set between the active transmission wheel 85 and the driven transmission wheel 82. The present application adopts the coupling wheel 83 and the coupling groove 87 to couple with each other to drive the mold cylinder 1 to rotate, rather than adopting the existing The advantage of the rotation method connected to the drive shaft in the technology is that it can leave open structures on both sides of the mold cylinder 1, thereby ensuring that there is enough space to install the feed hopper 2 and the top support and unloading device on both sides of the mold cylinder. When it is necessary to drive the mold cylinder 1 to rotate, the driving motor 84 drives the active transmission wheel 85 to rotate, and the driven transmission wheel 82 can be driven to rotate under the transmission action of the transmission belt 86, thereby driving the rotating shaft 81 to rotate. As the rotating shaft 81 rotates, the coupling wheel 83 can rotate, and thus the mold cylinder 1 can be driven to rotate through the friction generated between the mutually coupled coupling wheels 83 and the coupling groove 87.
