Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a forming mold for automobile crossbeam parts. Background Art

[0002] A mold is a tool that, under the action of external force, makes the blank become a part of a specific shape and size. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The application of a contour shape with a cutting edge can make the blank separate (punch out) according to the contour shape, and the application of an inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally consists of a movable mold and a fixed mold (or a punch and a die). The two parts can be separated and combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It withstands the expansion force of the blank and has high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

[0003] Various parts are welded onto the crossbeam of a car, such as connectors, supports, and fixings, to facilitate the installation of other components. These parts are usually formed by die stamping. Currently, the die structures on the market are relatively complex, difficult to maintain, and have high costs and low production efficiency.
