Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive cover plate molds, specifically, to an automotive cover plate manufacturing mold. Background Technology
[0002] The front hood of a car is a type of automotive body panel. Body panels mainly refer to parts that cover the car engine and chassis, form the cab, and constitute the car body. After assembly, body panels form the entire external and internal shape of the car body and cab. They are both decorative parts and load-bearing parts that are enclosed thin shells. The manufacturing of body panels is a key step in the manufacturing of car bodies. The front hood of a car is generally formed by stamping. Pressing machines and molds are used to press the sheet metal to produce plastic deformation or separation, thereby obtaining the required shape and size.
[0003] Chinese utility model patent application number CN202322031072.X, entitled "An Automobile Cover Forming Mold," discloses an automobile cover forming mold, including a bottom plate and a top plate. The top plate and the bottom plate are connected by multiple supporting telescopic rods. Two cylinders are arranged on the bottom plate at intervals on the left and right. The telescopic ends of the cylinders are vertically upward and fixedly connected to the top plate. A lower mold is provided on the bottom plate, and an upper mold is provided on the top plate opposite to the lower mold. The lower mold is connected to the bottom plate through a lower limiting structure, and the upper mold is connected to an upper limiting structure. The upper limiting structure is connected to the top plate through a buffer mechanism.
[0004] However, the above-mentioned patent still has the following shortcomings: when placing sheet metal raw materials, it lacks the positioning function of sheet metal, resulting in the problem of skewed sheet metal placement. In the existing technology, the sheet metal is pressed into shape and then the excess part of the edge is cut off. Because the sheet metal is stretched during pressing, the edge will move towards the center of the sheet metal. When the placement is skewed, the distance between some sheet metal edges and the mold is small, resulting in less reserved sheet metal. After pressing, there is a gap problem, which leads to the scrapping of the entire sheet metal material. Therefore, it is necessary to design a mold for manufacturing car cover plates.
