Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 2 to 7, a mold for preventing a convex hull of a part from being deformed in a concave manner comprises an upper mold and a lower mold, wherein the upper mold comprises a top plate 1, a mounting plate 2 and a discharging plate 3 are sequentially and fixedly arranged at the bottom of the top plate 1, a concave mold 4 is fixedly arranged in the discharging plate 3, the lower end part of the concave mold 4 extends below the discharging plate 3, a mounting groove is formed in the mounting plate 2, an upper padding plate 5 is arranged in the mounting groove, the upper padding plate 5 is fixedly arranged at the bottom of the top plate 1, a vertically arranged spring 6 is arranged in the upper padding plate 5, a material clamping column 7 is fixedly arranged at the bottom of the spring 6, the material clamping column 7 sequentially penetrates through the upper padding plate 5 and the concave mold 4 downwards, the material clamping column 7 extends outside the concave mold 4, the lower mold comprises a bottom plate 8, a convex mold plate 9 is sequentially and fixedly arranged on the top surface of the bottom plate 8, an insert, the upper end of the male die rod 11 extends to the outside of the male die insert 10, the male die rod 11 and the material clamping column 7 are coaxially arranged, and the top of the male die rod 11 is fixedly provided with a boss 12 with an arc-shaped cross section.

As shown in fig. 2 to 4, a guide hole is formed in the female die 4 along the axial direction thereof. The material clamping column 7 is in sliding fit with the guide hole. The bottom of the upper backing plate 5 is provided with a blind hole, and the spring 6 is fixedly arranged at the bottom of the blind hole. A concave die insert 13 is fixedly arranged in the discharging plate 3, and the concave die 4 is fixedly arranged in the concave die insert 13.

The working process of the utility model is as follows:

the worker connects the top plate 1 to the punch of the punch, the worker places the sheet material on the top surface of the boss 12, then the worker operates the punch to move the top plate 1 downwards, the clamp column 7 extends to the outside of the female die 4, so the clamp column 7 clamps the sheet material between the boss 12 and the clamp column 7, along with the continuous downward movement of the top plate 1, the male die rod 11 extends into the female die 4 to deform the sheet material upwards to form the convex hull of the part, the raised sheet material jacks up the clamp column 7, the clamp column 7 compresses the spring 6 when moving upwards, the female die 4 presses the outer edge of the sheet material downwards, and when closed, as shown in fig. 3-4, the finished convex hull part can be obtained, and the structure of the finished convex hull part is shown in fig. 5. After the male die rod 11 enters the female die 4, the boss 12 jacks up an arc-shaped bulge on the basis of the formed convex hull, the arc-shaped bulge is recovered downwards under stress, and the bulge with the plane top surface can be obtained after recovery. Therefore, the die greatly improves the qualification rate of the convex hull parts, greatly improves the quality of the parts with the convex hulls, and effectively prevents the concave deformation of the convex hulls after the parts are molded.

After the forming, the punch is operated to move the top plate 1 upwards, the die opening action is completed after the female die 4 is separated from the male die rod 11 as shown in fig. 2, meanwhile, the material clamping column 7 moves downwards under the restoring force of the spring 6, and the material clamping column 7 pushes the bulge of the finished convex hull part out of the female die downwards.
