[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4 A mold for processing a continuous mold of a right mounting bracket of a front suspension of an automobile comprises a support seat 1, two parallel support plates 2 are symmetrically arranged on the right side wall of the support seat 1, the support plate 2 is vertically arranged, the upper side wall of the support seat 1 is higher than the upper side wall of the support plate 2, a lower mold is fixedly arranged on the support seat 1 and the support plate 2, a positioning step is arranged at the upper left end of the support seat 1, and a notch matching the positioning step is opened at the left end of the lower mold, the arrangement of the positioning step and the notch is conducive to the rapid positioning of the lower mold and the support seat 1, the lower mold is Z-shaped, and the lower mold includes a horizontal template 1 3 and a template 2 4.

[0021] Template 1 3 and template 2 4 are respectively fitted with the upper walls of the support seat 1 and the support plate 2, and a vertical through hole 1 5 is opened on the upper side wall of template 2 4. The shape of through hole 1 5 is designed according to the shape of the workpiece processing hole. An upper mold is arranged on the upper side of the lower mold, and the upper mold is arranged in parallel with the lower mold. After the upper mold and the lower mold are combined, the bending processing of the workpiece will be completed. The upper mold includes a horizontal template 3 6 and a template 4 7, and template 3 6 and template 4 7 correspond to template 1 3 and template 2 4 respectively. The outer walls of template 3 6 and template 4 7 are symmetrically provided with connecting plates 8, and a vertical downward guide column 9 is fixed on the connecting plate 8. The outer walls of the support seat 1 and the support plate 2 are fixedly provided with a guide sleeve 10 corresponding to the guide column 9, and the guide column 9 is slidably arranged in the corresponding guide sleeve 10. A spring is fixedly connected between the lower end of the guide column 9 and the inner bottom wall of the corresponding guide sleeve 10. Under the elastic force of the spring, the guide column 9 lifts the upper mold to keep the upper mold and the lower mold separated, which is convenient for loading and unloading.

[0022] The upper wall of the template 47 is provided with a through hole 2 corresponding to the through hole 15. A hydraulic cylinder 11 located on the upper side of the through hole 2 is fixedly arranged on the upper side of the template 47. The driving end of the hydraulic cylinder 11 is vertically downward. The driving end of the hydraulic cylinder 11 is fixedly connected to a punch 12 located in the through hole 2. The upper side wall of the template 47 is symmetrically provided with limit plates 14 located on both sides of the through hole 2. The ends of the limit plates 14 are both extended into the through hole 2. The limit plates 14 are located on the upper side of the punch 12. When the punch 12 When in contact with the limit plate 14, the lower side wall of the punch 12 is flush with the lower side wall of the template 47. When the upper die and the lower die are closed, the hydraulic cylinder 11 is started to lower the punch 12. As the punch 12 extends into the through hole 5, the punch 12 completes the punching process on the workpiece. Since the punching is completed in the closed state, the position accuracy of the processed hole of the bent workpiece is guaranteed. In addition, compared with single-step stamping, the time for repositioning is saved, thereby improving the efficiency of workpiece forming.

[0023] The spacing between the two support plates 2 is greater than the maximum size of the through hole 15. The waste generated by punching will fall directly from the through hole 15 to the bottom, which is convenient for the later waste collection. The outer wall of the upper mold is fixedly connected with a bracket 13, and the bracket 13 is fixedly connected to the external driving mechanism. The driving mechanism includes a hydraulic cylinder 2. The function of the hydraulic cylinder 2 is to drive the upper mold to move, thereby completing the closing and opening of the upper and lower molds.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
