Improved oblique shock wave die structure for basin stand product

Abstract

The invention relates to the technical field of dies, and discloses an improved oblique shock wave die structure for a basin stand product. The improved oblique shock wave die structure comprises an upper die, a lower die and a sliding chute structure arranged between the upper die and the lower die, wherein the upper die comprises an upper padding plate, an upper fixing plate and a male die; the lower die comprises a female die, a limiting block, a lower padding plate and a female die padding plate; the sliding chute structure comprises a guide rail plate and a sliding block, an oblique sliding face is arranged on the guide rail plate and provided with a guide groove, a guide block matched with the guide groove is arranged on the sliding block, and the sliding block is further provided with a male die via hole matched with the male die; the upper fixing plate is installed at the lower end of the upper padding plate, the upper end of the sliding block corresponds to the lower end of the upper fixing plate, the guide rail plate is located at the upper end of the limiting block, the female die is installed on the lower padding plate through the female die padding plate, the limiting block is installed on the lower padding plate, the sliding block is further provided with an elastic recovery device, and the guide groove and the guide block are of a square structure. The improved oblique shock wave die structure has the advantages that machining is easy to carry out, stress is balanced in the working process, and the service life of the dies is prolonged.

Description

technical field [0001] The invention relates to the technical field of moulds, and more specifically relates to an improved oblique punching mold structure for pot frame products. Background technique [0002] Such as figure 1 As shown in , it is a structural diagram of an existing typical pot frame product, which is a stepped product with a slope in structure. In the production of continuous molds, excess material needs to be punched out at A and B to obtain windows. In the design of the mold structure, since the pot frame products have inclined surfaces, oblique punching is generally used for punching. [0003] Such as figure 2 As shown, the punching method in the prior art adopts the chute structure of the slider and the guide rail plate. More precise guidance and accurate punching; however, in the actual processing of the mold, it is difficult to ensure the parallelism and flatness of multiple surfaces at the same time, and the ideal state cannot be achieved. At the...

[0003] like figure 2 As shown, the punching method in the prior art adopts the chute structure of the slider and the guide rail plate. More precise guidance, accurate punching; but in the actual process of mold processing, it is necessary to ensure the parallelism and flatness of multiple surfaces at the same time, the processing is more difficult, and the ideal state cannot be achieved

At the same time, when the material is returned, because there are too many contact surfaces, there is friction between the surfaces, so that the spring will produce unbalanced force when the material is returned. The force analysis of the structure is as follows: image 3 As shown, it includes stripping force F1, punch friction force F2, stripping spring force F3, self-gravity G and T-slot friction force F4. Since T-slot friction force F4 has many stress surfaces, in production practice The slider 23 and the punch are easily stuck in the guide rail plate 20, and when the punch is not completely withdrawn from the die and the mold starts to move upward, the mold will explode, which directly reduces the service life of the mold
