Detailed Description

As shown in fig. 1 and referring to fig. 2 to 6, the mold with the shaping angle convenient to adjust according to the present utility model comprises an upper mold base 1 located above and a lower mold base 6 located below, wherein an upper fixing plate 2 is fixedly connected below the upper mold base 1, a stripper plate 3 is arranged below the upper fixing plate 2, the stripper plate 3 is connected with the upper mold base 1 through a spring and an equal-length bolt, a lower mold 4 is fixed above the lower mold base 6, and a lower mold insert 5 which is matched with a product 12 is fixedly inlaid on the lower mold 4, and the conventional structure of the conventional mold is not described in detail. A slidable shaping slide 8 is provided in the lower die insert 5, i.e. the shaping slide 8 is slidable in the lower die insert 5. A return spring 7 (as shown in fig. 1) is provided between the lower side surface of the shaping slider 8 and the lower die insert 5. The lower die insert 5 and the shaping slide 8 are respectively provided with a lower die insert inclined surface 17 and a shaping slide inclined surface 16 which are opposite, wherein the lower part of the lower die insert inclined surface 17 is inclined inwards (shown in figure 6), the upper part of the shaping slide inclined surface 16 is inclined inwards (shown in figure 4), and the shaping slide (8) is provided with a stamping inclined surface 18 (shown in figure 4). The lower surface of the upper die holder 1 is provided with a concave part 19, one end of the sliding cushion block 10 is inserted into the concave part 19, a plurality of steps 13 are arranged below the sliding cushion block 10, the side edge of the other end of the sliding cushion block 10 is provided with a plurality of openings 14, the fixed cushion block 11 is matched with the openings 14, and the fixed cushion block 11 is connected with the upper die holder 1 through screws. The upper end side of the shaping wedge 9 is provided with a hanging table 21, and the shaping wedge 9 passes through the upper fixing plate 2 and is hung on the upper fixing plate 2 through the hanging table 21. The upper end of the shaping wedge 9 is propped against the step 13, the shaping wedge 9 passes through the stripper plate 3, and the lower end of the shaping wedge 9 is provided with a wedge inclined surface 20 matched with the stamping inclined surface 18.

The working process is as follows: the upper die holder 1 is arranged on a stamping slide block component at the upper part of the stamping machine, the lower die holder 6 is arranged on a workbench below the stamping machine, the upper die holder 1, the upper fixing plate 2, the stripper plate 3 and the shaping wedge 9 are positioned at upper positions before shaping stamping, under the action of the reset spring 7, the shaping slide block 8 is separated from the lower die insert 5 by a certain distance, a product 12 (shown in figure 3) stamped in the previous procedure is arranged on the lower die insert 5, the stamping slide block in the stamping machine moves downwards to drive the upper die holder 1, the upper fixing plate 2, the stripper plate 3 and the shaping wedge 9 to move downwards,

when the wedge inclined surface 20 contacts with the stamping inclined surface 18, the shaping wedge 9 gives a rightward horizontal force to the shaping slide 8, so that the shaping slide 8 moves rightward, the reset spring is compressed, the shaping slide inclined surface 16 presses the product 12, and the bending part 15 of the product 12 can be bent inwards due to the fact that the lower die insert inclined surface 17 is arranged on the lower die insert 5, namely, the bending angle is smaller than 90 degrees, the bending part 15 of the product 12 is outwards stretched to a certain extent after the stamping slide of the stamping machine returns, and the bending angle and the outwards stretching angle are mutually complemented, so that the bending part of the product 12 is just in a 90-degree state.
