Description

Technical Field

[0001] This utility model relates to the field of forming molds, and in particular to a forming mold for workpiece processing. Background Technology

[0002] When machining a cylindrical workpiece, it is necessary to ensure that the diameters at the top and bottom of the workpiece are the same, while the diameter at the middle is larger than the diameters at the top and bottom (as shown in the attached diagram in the instruction manual). Figure 5 (As shown in the image); therefore, forming molds are needed to process the workpieces. However, when processing cylindrical workpieces, the diameter of the inner middle part of the workpiece is larger than the diameter of the upper inner part after the workpiece is formed, which makes demolding difficult and causes great trouble for the workpiece processing. Utility Model Content

[0003] This utility model discloses a forming mold for workpiece processing, which solves the problem that it is not easy to demold the workpiece after it has been processed and formed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A forming mold for workpiece processing includes a guide ring, a lower pad fixed to the inner side of the guide ring, a lower die located on top of the lower pad fixed to the inner side of the guide ring, an upper die above the lower die, a liftable upper pad above the upper die, a deformable colloid passing through the inner side of the upper die fixed to the bottom of the upper pad, a press for driving the upper pad above the upper die, a first spring connected to the top of the upper die fixed to the bottom of the press, and a through hole for the first spring to pass through on the upper pad.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After placing the cylindrical workpiece inside the lower die and supporting it with the lower pad, the press is started to drive the upper pad downwards. As the upper die moves downwards, it first contacts the lower die. At this point, the bottom of the colloid inserts into the workpiece and contacts its bottom. Then, the press continues to drive the upper pad downwards, compressing the first spring. As the upper pad continues downwards, the colloid begins to deform, squeezing the inner wall of the workpiece. This causes the outer wall of the workpiece to fit against the inner walls of the upper and lower dies, completing the workpiece processing. Then, the press drives the upper pad upwards to return to its original position. As the upper pad moves, the colloid returns to its original position and moves upwards. Once the colloid has moved outside the workpiece, it can be removed from the inside of the lower die. This invention allows for rapid processing and shaping of the workpiece, followed by separation and demolding. The demolding process is simple and fast. Attached Figure Description

[0015] The specific content of the utility model will be described in detail below in combination with the drawings and examples.

[0016] As shown in Figure 1 , Figure 2 and Figure 3 , the utility model provides a forming die for workpiece processing, including pilot ring 1, the inner side of pilot ring 1 is fixed with lower base plate 2, the inner side of pilot ring 1 is also fixed with lower die 3 located at the top of lower base plate 2, the upper side of lower die 3 is equipped with upper die 4, the upper side of upper die 4 is equipped with liftable upper base plate 5, the bottom of upper base plate 5 is fixed with gel 6 that can be deformed and passes through the inner side of upper die 4;The upper side of upper die 4 is equipped with press 7 for driving upper base plate 5, the bottom of press 7 is fixed with No. 1 spring 8 connected with the top of upper die 4, and the perforation for No. 1 spring 8 is set up in upper base plate 5.

[0017] As shown in Figure 1 , Figure 5 and Figure 3 , the bottom of upper die 4 is fixed with positioning column 41, and the top of lower die 3 is equipped with positioning hole 31 corresponding with positioning column 41. Upper die 4 moves downward and contacts lower die 3, positioning column 41 is inserted into positioning hole 31, and upper die 4 is positioned, which ensures that upper die 4 and lower die 3 can be accurately corresponded together.

[0018] As Figure 1 , Figure 2 and Figure 3 shown, the glue 6 uses the super glue. The super glue has the rigidity of plastic and the elasticity of rubber, so that the workpiece can be quickly recovered after processing.

[0019] As Figure 1 , Figure 2 and Figure 3 shown, the top of the lower bolster plate 2 is provided with a groove, and the groove is slidably connected with a top block 21 located in the lower die 3, and the bottom of the top block 21 is fixedly connected with a second spring 22 connected with the bottom of the groove. When the workpiece is extruded, the top block 21 enters the groove and compresses the second spring 22; when the workpiece is processed and the upper bolster plate 5 is recovered, the second spring 22 is recovered to push the workpiece upward by the top block 21, so that the workpiece can be taken out of the lower die 3 by the worker.

[0020] In use, the cylindrical workpiece is placed inside the lower die 3, and the lower bolster plate 2 supports the workpiece, and then the press 7 drives the upper bolster plate 5 to move downward (the extension end of the press 7 is fixedly connected with the top of the upper bolster plate 5), and the upper die 4 is first contacted with the lower die 3 after moving downward, at this time, the bottom of the glue 6 is inserted into the workpiece and contacted with the bottom of the workpiece; then the press 7 continues to drive the upper bolster plate 5 to move downward, so that the first spring 8 is compressed, and the glue 6 starts to deform and extrude the inner wall of the workpiece as the upper bolster plate 5 continues to move downward, and when the bottom of the upper bolster plate 5 is contacted with the top of the upper die 4, the outer wall of the workpiece is attached to the inner wall of the upper die 4 and the lower die 3, and the processing of the workpiece is completed; then the press 7 drives the upper bolster plate 5 to recover upward, and the glue 6 recovers and moves upward after the upper bolster plate 5 moves, and the workpiece can be taken out of the lower die 3 when the glue 6 moves to the outside of the workpiece.
