Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1, 2 and 3, the present invention includes an upper mold structure 1 and a lower mold structure 2. The upper die structure 1 includes an upper die base plate 10, a pressure plate 11, and a punch mount 15. The lower die structure 2 includes a lower die base plate 23, a mount 20, and a punch support base 21. The pressure plate 11 and the punch mounting seat 15 are mounted on the upper die base plate 10, and the mounting seat 20 and the punch support seat 21 are mounted on the lower die base plate 23. The upper die base plate 10 and the lower die base plate 23 are oppositely arranged on the mounting surface and used for processing products.

As shown in fig. 2 and 3, a space is provided between the punch supporting seat 21 and the mounting seat 20; one side surface of the mounting seat 20 is a working surface, and the top surface of the mounting seat 20 is a matching fixing surface. The working face is adjacent to the punch support seat 21. The working surface is the side punched by the punch, and the matched fixing surface is used for storing the workpiece to be machined. The position of the pressure plate 11 corresponds to the position of the mount 20, and the position of the punch mount 15 corresponds to the position of the punch support base 21. The top surface of the material pressing plate 11 is a pressing working surface; a punching channel is arranged on one side surface of the material pressing plate 11; the punch channel is adjacent to the punch mount 15. The pressing working surface is opposite to the matching fixing surface, and the pressing working surface is matched with the matching fixing surface to press the workpiece to be machined. The punch channel is operative with the punch.

The number of the working faces on the mounting seat 20 is at least two, the number of the matching fixing faces, the number of the pressing working faces and the number of the punching channels are all consistent with the number of the working faces, the number of the punch supporting seats 21 is consistent with the number of the working faces, and the number of the punch mounting seats 15 is consistent with the number of the punch supporting seats 21 and corresponds to the positions of the punch supporting seats.

In this embodiment, as shown in fig. 3, there are two working surfaces on the mounting base 20, namely a first working surface 202 and a second working surface 203. The two matching fixing surfaces on the mounting seat are a first matching fixing surface 201 and a second matching fixing surface 200 respectively. The first mating attachment surface 201 is attached to the first work surface 202 and the second mating attachment surface 200 is attached to the second work surface 203. Because the workpiece to be machined is in an irregular shape, the first matching fixing surface 201 is designed into a shape which can be embedded when one end surface of the workpiece to be machined is machined, and the second matching fixing surface 200 is designed into a shape which can be embedded when the other end surface of the workpiece to be machined is machined; and the first working surface 202 and the second working surface 203 are also designed into structures for processing end surfaces and designing the positions of punched holes.

In this embodiment, as shown in fig. 2, the pressing working surfaces on the pressing plate 11 include a first pressing working surface 110 and a second pressing working surface 111. The punching channels comprise a first punching channel 17 and a second punching channel 12. The first press-fit working face 110 is communicated with the first punching channel 17; the second pressing working surface 111 is communicated with the second punching passage 12. The first pressing working surface 110 is opposite to the first matching fixing surface 201, and the second pressing working surface 111 is opposite to the second matching fixing surface 200, so that the first pressing working surface 110 and the second pressing working surface 111 are respectively designed into grooves which can be matched with the workpiece to be machined, and the workpiece to be machined is perfectly matched with the upper die and the lower die during punching. The punching channel is one of the most important structures of the punching process. Since the punch mounting seat 15 is located on the upper die base plate 10 and the working surface of the mounting seat 20 is located on the lower die base plate 23, the punch must be installed obliquely, and thus the punching passage is also obliquely provided.

In the present embodiment, as shown in fig. 2, the punch mount 15 includes a first punch mount 151 and a second punch mount 150. The first punch mounting seat 151 and the second punch mounting seat 150 are respectively provided with a punch, the punch is sleeved with the stripping structure 14, and the punch and the stripping structure 14 are erected on the adjacent first punching channel 17 and the second punching channel 12. When the upper die structure 1 and the lower die structure 2 are combined and work, the stripping structure 14 is in contact with a workpiece to be processed, the stripping structure is sleeved on the outer side of the punch, and when the punch returns after punching is finished, the workpiece is smoothly separated from the punch by using the interference force of the stripping device. The stripping structure is generally made of soft material.

As shown in fig. 2, protruding stoppers 13 are respectively provided on both sides of the first punched passage 17 and the second punched passage 12. The stop block 13 has a limiting effect, and after the machined part is machined, the punch is prevented from driving the workpiece to dislocate.

As shown in fig. 1, the upper mold base plate 10 and the lower mold base plate 23 are provided with the stopper posts 3 at corresponding positions. When the upper die structure 1 and the lower die structure 2 are combined, the upper limiting column 3 and the lower limiting column 3 are contacted, which shows that the processing position of the workpiece to be processed is reached. The influence on the processing quality of the product due to excessive combination is avoided. The lower die base plate 23 is provided with a guide post 4, the upper die base plate 10 is provided with a through hole 100 corresponding to the guide post 4, the through hole 100 is provided with a guide sleeve 5 extending outwards, and the top end of the guide post 4 extends into the guide sleeve 5. When the upper die base plate 10 moves downwards, the upper die base plate is prevented from deviating, and the guide posts 4 on the lower die base plate 23 are specially arranged to be matched with the upper die base plate. The downward movement process of the upper die base plate 10 is guaranteed, the position is accurate, deviation does not occur, and finally products meeting requirements can be matched with the lower die base plate 23 and processed.
