Stamping die used for manufacturing hinge fixing plate on automobile door

Abstract

The invention relates to the related technical field of dies, and in particular relates to a stamping die used for manufacturing a hinge fixing plate on an automobile door. The stamping die comprises a heat insulation plate, an upper die holder plate, a hot runner plate, an upper die plate, a lower die plate, an ejector rod fixing plate, an ejector rod backing plate, a lower die base plate and a heat insulation plate which are arranged from top to bottom; an inclined guide pillar, an inclined wedge, a sliding block seat, a wear-resisting block, a sliding block insert, a precise positioning block and oil temperature connectors are arranged from top to bottom on backs of the hot runner plate, the upper die plate and the lower die plate. According to the die, a plurality of working procedures for traditionally producing a screw tooth plate are combined in design, a plurality of working procedure for manufacturing the screw tooth plate can be finished by using the same die, once punching is enough for forming the screw tooth plate, the labor productivity can be greatly improved, the manufacturing cost is reduced, and the energy consumption is saved; at the same time, a material upsetting technology is adopted, so that a material used for manufacturing a screw hole part of the screw tooth plate achieves technical conditions, a requirement of screw thread machining on the material is met, and the screw thread strength is improved.

Description

Technical field [0001] The invention relates to the technical field of molds, and in particular to a stamping mold for manufacturing a hinge fixing plate of an automobile door. Background technique [0002] When the car door hinge fixing plate is processed with ordinary molds, the material will become thinner during the drawing process of the stamping parts, so that the wall thickness of the screw hole of the processed door screw plate does not meet the technical requirements, the thread strength is low, and the processing efficiency is low. The qualified rate of finished products is low, and the production cost is high. Summary of the invention [0003] In view of the defects or deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a stamping die for manufacturing automobile door hinge fixing plates, which can greatly increase the processing efficiency of automobile door hinge fixing plates and improve the qualified rate of finis...

AI Technical Summary

Problems solved by technology

[0002] When processing the fixed plate of the automobile door hinge with a common mold, the material will become thinner during the stretching process of the stamping part, so that the wall thickness of the screw hole of the processed car door screw tooth plate cannot meet the technical requirements, the thread strength is low, and its processing efficiency is low. The qualified rate of finished products is low and the production cost is high
