Abstract
Description
Technical Field
[0001] This utility model relates to automotive component forming molds, and more particularly to a stamping forming mold for an automotive door inner panel support frame. Background Technology
[0002] The automotive door inner panel support frame is used for supporting the inner part of the door panel, thus protecting the door. In recent years, with the rapid development of my country's automotive industry, people's requirements for automotive interiors have become increasingly higher. The automotive door inner panel support frame is an important component of the automotive door system, needing to meet requirements in terms of ergonomics, comfort, and functionality. Traditional progressive forming dies used in the processing of automotive door inner panel support frames simply design the mold structure based on the shape. The mold structure is complex and poorly designed, leading to high mold development costs. Furthermore, in traditional molds, the upper and lower dies directly contact each other to stamp the workpiece. Due to the rapid mold closing process and short stamping and shaping times, the forming contour surface accuracy of the workpiece is not high. The trimming process uses the cooperation between the upper and lower dies to remove the edges of the workpiece.
[0003] Traditional edge trimming dies are prone to incomplete trimming due to short stamping time, resulting in poor edge forming of the car door inner panel support frame, deformation at the edge of the car door inner panel support frame, and excessive number of stamping and scrap removal operations, making it impossible to guarantee the accuracy of the cutting.
[0004] Therefore, there is an urgent need for a car door inner panel support frame that can solve the above problems to improve the stamping quality of the car door inner panel support frame, which affects the forming quality of parts and manufacturing progress. Utility Model Content
[0005] The purpose of this utility model is to provide a stamping die for a support frame of an automotive door inner panel, which solves the problem that the moving die and the fixed die are not smoothly closed due to the influence of external forces and vibrations, and that the displacement is easy to occur, resulting in inaccurate stamping of the automotive door sill interior panel and affecting the stamping quality.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a stamping forming die for an inner panel support frame of an automobile door, including a lower die structure, an upper die structure, and a pressure ring structure disposed between the upper die structure and the lower die structure. The upper die structure includes an upper die body, an upper die body auxiliary component disposed in the upper die body, and an upper die forming cutter structure disposed in the upper die body. The lower die structure includes a lower die body, a lower die body auxiliary component disposed in the lower die body, and a lower die forming cutter pedestal structure disposed in the lower die body. The pressure ring structure includes a pressure ring external connecting structure disposed in the upper die structure and a pressure forming body structure disposed in the pressure ring external connecting structure. The pressure forming body structure includes a pressure ring body structure that matches the upper die forming cutter structure, and a pressure ring body fixing connector assembly disposed on the outer periphery of the pressure ring body structure. The pressure ring body structure includes an upper first pressure ring cutter body, an upper second pressure ring cutter body, a lower first pressure ring cutter body, and a lower second pressure ring cutter body.

[0008] An external auxiliary component for the pressure ring is provided between the pressure ring connector and the pressure ring body structure. The external auxiliary component for the pressure ring includes a pressure ring cast-in lifting bar, a pressure ring positioning key, and a pressure ring side end pressure plate assembly.
[0009] The auxiliary components of the upper mold body include an upper mold casting-in lifting bar, an upper mold outer guide plate, an upper mold pier dead block, an upper mold positioning key, and an upper mold side pressure plate, all located in the upper mold body.
[0010] The auxiliary components of the lower mold body include a lower mold casting-in lifting bar, a lower mold outer guide plate, a lower mold pier dead block, a lower mold positioning key, and a lower mold side pressure plate, all located in the lower mold base.
