[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in the present embodiment, a C-type sheet metal processing rapid prototyping mold comprises a processing table 1, a lower mold 2 is fixedly connected to the upper end of the processing table 1, an upper mold 3 is arranged above the lower mold 2, a mold groove 4 is opened on the lower mold 2, and the mold groove 4 is an arc surface structure. The upper end of the lower mold 2 is located on both sides of the mold groove 4 and is provided with material guide grooves 6 acting on the sheet metal, a feed push plate 7 is arranged in the material guide groove 6, and the two ends of the bottom of the feed push plate 7 are respectively fixedly connected with guide blocks 18, and the guide block 18 is slidably installed in the guide groove 19 opened in the processing table 1, one end of the feed push plate 7 is connected with a reset component, and a feed push plate 13 is arranged at the bottom of the feed push plate 7, the feed push plate 13 is an arc plate and slides in contact with the inner wall of the mold groove 4, and the feed push plate 13 is fixedly connected to the feed push plate 7 through a connecting column 8.

[0021] Among them, the reset component includes a connecting rod 9, a movable plate 10, a mounting table 11, a fixed plate 12 and a reset spring 14. The movable plate 10 is fixedly connected to the feed push plate 7 through the connecting rod 9. A slider 17 is fixedly connected to the bottom of the movable plate 10. The slider 17 is slidably installed in a slide groove 16 opened on the mounting table 11. The mounting table 11 is fixedly connected to the processing table 1. The side of the upper end of the processing table 1 away from the movable plate 10 is fixedly connected with the fixed plate 12, and a reset spring 14 is fixedly connected between the fixed plate 12 and the movable plate 10.

[0022] During use, when the feed push plate 7 pushes the sheet metal, the movable plate 10 will move toward the fixed plate 12 and compress the reset spring 14. When the feed push plate 7 is released, the movable plate 10 will return to its original position under the action of the reset spring 14 restoring the deformation, thereby driving the feed push plate 7 to return to its original position.

[0023] A material guide plate 20 is disposed at the tail of the lower die 2 , the material guide plate 20 is fixedly connected to the processing table 1 , and the material guide plate 20 is tilted relative to the horizontal plane.

[0024] The material guide plate 20 can be used to guide the C-shaped sheet metal being cut.

[0025] A movable rod 15 is inserted into the inner side of the return spring 14 , one end of the movable rod 15 is fixedly connected to the side wall of the movable plate 10 , and the other end of the movable rod 15 slides through the fixed plate 12 .

[0026] Since the return spring 14 is relatively long, the return spring 14 may deviate to the left or right during the compression process. The movable rod 15 can avoid the above situation.

[0027] The two material guide grooves 6 are respectively fixedly connected with the limiting blocks 5 .

[0028] By setting the limit block 5, the feeding sheet metal can be limited to prevent the sheet metal feeding position from being too deep and escaping from the bottom of the upper mold 3.

[0029] The utility model provides a C-shaped sheet metal processing rapid forming die, and the specific working principle is as follows:

[0030] After the upper die 3 and the lower die 2 are closed, the sheet metal is stamped into a C-shaped sheet metal and is located in the die groove 4. Then, the next sheet metal is placed in the material guide trough 6 and the feed push plate 7 is continued to be pushed. At this time, the feed push plate 7 will push the sheet metal to the bottom of the upper die 3, and the unloading push plate 13 fixedly connected to the feed push plate 7 will push the C-shaped sheet metal in the die groove 4 away from the bottom of the upper die 3. The above operation is repeated, and the C-shaped sheet metal can be unloaded while the sheet metal is being loaded, so as to avoid the time waste caused by frequent material extraction, thereby effectively improving the work efficiency. It should be noted that a collection box should be placed under the guide plate 20 to collect the unloaded C-shaped sheet metal.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
