The cross-section of the guide chute is trapezoidal, and rollers are evenly distributed on the slope inside the guide groove, and the slope of the slider is in contact with the rollers.

The length of the slider is greater than the distance between two adjacent rollers.

The section of the discharge rod is rectangular.

The lower surface of the discharge rod is at the same height as the upper surface of the lower mold.

The first support member and the second support member are rod-shaped members, and the cross sections of the first support member and the second support member are rectangular.

A reinforcing rod is arranged between the first support member and the second support member.

The left end surface of the elastic material part is an arc surface.

The beneficial effect of the present invention is that: the entire stamping die spring material device is arranged on the outside of the mold, which avoids setting holes on the mold for installing the stamping die spring material device, avoids the processing of the mold, makes the assembly more convenient, and ensures the forming The quality; and, the whole device realizes the horizontal separation of the stamping workpiece from the mold, ensuring the continuity of the stamping workpiece.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

As shown in Figures 1 and 2, a stamping die spring material device includes an upper die 1, a lower die 2, a first support 3, a second support 4, a support plate 5, a discharge rod 6, a connecting rod 7 and Rotary rod 8, one end of the first support 3 is connected to the side of the lower mold 2, the other end of the first support 3 is connected to one end of the second support 4, and the other end of the second support 4 is connected to the support The plates 5 are connected, and the support plate 5 is set horizontally. The lower surface of the discharge rod 6 is provided with a slider 9, the cross section of the slide block 9 is trapezoidal, and the upper surface of the support plate 5 is provided with a guide that is compatible with it. chute 10, the slider 9 is placed in the guide chute 10; the connecting rod 7 is fixedly connected with the upper mold 1, and the connecting rod 7 is located above the support plate 5, and one end of the rotating rod 8 is connected to the The rod 7 is hinged, and the other end of the rotating rod 8 is hinged with the discharge rod 6; the left end surface of the discharge rod 6 is provided with a groove, and a spring 13 is arranged in the groove, and one end of the spring 13 is connected with the discharge rod 6, and the spring 13 The other end of the is connected with elastic material part 14.

As shown in Figures 1 and 3, the section of the guide chute 10 is trapezoidal, and the inclined surface in the guide chute 10 is provided with evenly distributed rollers 11, and a plurality of rollers 11 are arranged along the direction of the guide chute 10, The inclined surface of the slider 9 is in contact with the roller 11 . The length of the slider 9 is greater than the distance between two adjacent rollers 11 . The cross-section of the discharge rod 6 is rectangular. The lower surface of the discharge rod 6 is at the same height as the upper surface of the lower mold 2 . The first support member 3 and the second support member 4 are rod-shaped members, and the cross sections of the first support member 3 and the second support member 4 are rectangular. A reinforcing rod 12 is arranged between the first support member 3 and the second support member 4 .
