DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 To Attachment Figure 7The principles and features of the present invention are described. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] A workpiece support structure for a spoke processing and shaping process comprises a fixing block 1, a fixing plate 3, a support plate 4 and a top block 7.

[0027] The fixing block 1 is connected to the upper mold 2 of the spoke processing mold. Specifically, a column 17 extending downward is connected to the upper mold 2. The fixing block 1 is provided with a threaded hole. The fixing block 1 is connected and fixed to the column 17 through the threaded hole. The fixing plate 3 is connected to the fixing block 1. The support plate 4 is rotatably connected to the fixing plate 4. Specifically, the support plate 4 includes an integrally formed supporting portion 6 and a baffle portion 10. The supporting portion 6 and the baffle portion 10 form an "L" shape. A pin 11 is connected at the intersection of the baffle portion 10 and the supporting portion 6. The support plate 4 is rotatably connected to the fixing plate 3 through the pin 11. The support plate 4 can complete a 90° rotation relative to the fixing plate 3. Specifically, the support plate 4 has two extreme positions, one of which is defined as the first extreme position and the other as the second extreme position. At the first extreme position, the supporting portion 6 is in a horizontal state; at the second extreme position, the supporting portion 6 is in a vertical state. The top block 7 can push the supporting portion 6 from the second extreme position to the first extreme position. In order to smoothly flip the support plate 4 from the second limit position to the first limit position, a counterweight block 18 is provided at the end of the supporting portion 6. Specifically, the upper surface of the supporting portion 6 is used to support the workpiece 5, and the counterweight block 18 is connected to the lower surface of the supporting portion 6.

[0028] The fixing plate 3 is provided with a first fan annular groove 8 and a second fan annular groove 12, wherein the first fan annular groove 8 and the second fan annular groove 12 are concentrically arranged, wherein the central angle of the first fan annular groove 8 is 90°. A guide wheel 9 is connected to one side of the baffle portion 10, and the guide wheel 9 extends into the first fan annular groove 8. A spring 13 is arranged in the second fan annular groove 12, and the top block 7 is slidably connected to the second fan annular groove 12 and connected to one end of the spring 13. The top block 7 includes a block body 14 and a stop pin 15, wherein the stop pin 15 is connected to the block body 14 by a thread, and the stop pin 15 can protrude to the surface of the block body 14 or be completely received in the block body 14. When the support plate 4 rotates from the first limit position to the second limit position under the action of an external force, the support plate 4 can gradually press the stop pin 15 until the spring 13 is pressed to the shortest; when the external force disappears, the spring 13 pushes the support plate 4 from the second limit position to the first limit position again through the top block 7.

[0029] When the pallet 4 is needed to extract the workpiece 5, the stop pin 15 is moved to the surface of the protruding block 14. When the upper mold 2 approaches the lower mold 16, the pallet 4 is flipped from the first extreme position to the second extreme position under the action of the unformed workpiece; when the upper mold 2 and the lower mold 16 are fitted together, under the action of the top block 7 and the spring 13, the pallet 4 is flipped from the second extreme position to the first extreme position; finally, after the upper mold 2 and the lower mold 16 are separated, the workpiece 5 can be taken away at the same time; when the pallet 4 is no longer needed to extract the workpiece 5, the stop pin 15 is completely stored in the block 14. After the pallet 4 rotates from the first extreme position to the second extreme position, it does not need to be rotated from the second extreme position to the first extreme position because there is no action of the top block 7.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
