Detailed Description

The utility model provides a mould structure for deburring parts, which comprises: the purpose of deburring negative angle achieved by combining the driving slotting tool 24 and the chamfering insert 14 is achieved, and the deburring negative angle is not achieved by simply stamping two parts like the prior art, the utility model drives the slotting tool 24 to press down from the front, touches the back tool seat 11 to continuously descend and then contact the lower slide block 9, then drives the slide block to contact a product, the lower slide block 9 is embedded with the chamfering insert 14, and the surface of the chamfering insert 14 contacting with the part is provided with a profile matched with the part, thereby not only avoiding the problem of stamping precision of the single-forming punch 14, but also ensuring the precision of the product, moreover, the chamfering insert 14 also has the function of side-pressing negative angle of the part, the material pressing insert 14 enables the part not to have position deviation in the horizontal direction, and simultaneously, the side surface of the part can be chamfered in a closed state by driving the slotting tool 24 to contact with the lower slide block 9, thus the position fixing is carried out from the upper side, the lower side and the left of the part, this also assists in increased accuracy.

In order to improve the consistency of the upper and lower positions of the upper die holder 1 and the lower die holder 7 in the stamping process, an outer guide pillar 8 is arranged between the upper die holder 1 and the lower die holder 7, the lower end of the outer guide pillar 8 is fixed on the lower die holder 7 through clearance fit, and a guide sleeve tightly matched with the outer guide pillar 8 is arranged on the upper die holder 1.

In order to make the stripper plate 4 have good compressibility and automatically complete the separation action of the upper clamping plate 3 and the stripper plate 4 after the punching is completed, an upper die spring 21 is further arranged on the upper die base 1.

In order to enable the upper die holder 1, the upper clamping plate 3 and the discharging plate 4 to be integrally connected and achieve the limiting effect on the discharging plate 4, a countersunk hole is formed in the upper die holder 1, a limiting bolt 23 is inserted into the countersunk hole and sequentially penetrates through the upper backing plate 2 and the upper clamping plate 3, and the bottom of the limiting bolt 23 is fixedly connected with the discharging plate 4.

The specific connection relation of the utility model is as follows:

the use process of the utility model is as follows:

during punching forming, the upper die holder 1 vertically moves downwards along the outer guide post 9 under the action of the upper table surface of the punch until the stripper plate 4 is attached to the upper surface of the part, and continues to move downwards until the lower surface of the part is attached to the lower die plate 5, so that the parts are pressed and positioned (as shown in fig. 1);

the upper die holder 1 continues to move downwards, the upper die spring 21 starts to be compressed, the upper clamping plate 3 moves downwards and is completely attached to the discharging plate 4, the molded surface of the chamfer insert 14 and the part are punched, burrs are pressed off, and the lower dead point of the punch press is reached (as shown in fig. 2);

after punching is finished, the upper table surface of the punch drives the upper die holder 1 to move upwards, the upper clamping plate 3 is separated from the discharging plate 4 under the action of the compression force of the material pressing spring 21, and the ejector rod 17 ejects parts out of the lower die plate 5 under the action of the compression force of the material floating spring 18 to finish primary stripping; the upper die holder 1 continues to move upward until reaching the top dead center (as shown in fig. 3).

The die has the advantages of simple structure, convenient manufacture and lower cost.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
