A Mold Structure for Eliminating Wrinkles on the Outer Wall of the Door Inner Panel and Window Frame

Abstract

The invention discloses a mold structure for eliminating wrinkles of the vertical wall outside the window frame of the inner panel of the automobile door. The shape of the rounded corner R1, the shape of the concave rounded corner R2 is also set on the supplementary surface of the concave mold technology matched with the supplementary surface of the convex mold process, the concave rounded corner R2 matches the shape of the convex rounded corner R1 surface, and the convex rounded corner The shape length direction of R1 conforms to the shape length direction of the concave fillet R2. The invention can solve the problem of wrinkling of the outer vertical wall of the existing automobile door inner panel and window frame, improve the surface quality of stamping single parts, thereby improving the quality of the whole vehicle.

Description

A mold structure for eliminating the wrinkle of the outer vertical wall of the inner panel and window frame of the car door technical field The present invention relates to the technical field of vehicle engineering, particularly relate to a kind of deep drawing die structure of automobile door inner panel. Background technique [0002] With the continuous development of the automobile industry, users pay more attention to automobile protection while pursuing the beautiful appearance of automobiles. Hit safety. In order to better absorb the impact energy on the side of the door, the depth of the inner panel of the door continues to increase, followed by the inner door of the car. The depth of the window frame is getting deeper and deeper, the concave fillet at the root of the reverse molding is generally about R5mm, which is very small, and the draft angle of the vertical wall outside the window frame is also small. It is small and has a deep forming depth, resulting in...
