Abstract

The utility model relates to an automobile die technical field, an embodiment of the present disclosure provides a four corners turn-ups plastic mould, and it is including the mould, the mould is including the base, the top of base is provided with the bed die, the inside of bed die is provided with demoulding mechanism. Compared with the traditional four-corner flanging shaping die, the four-corner flanging shaping die ejects the automobile covering part from the lower die forming block through the upward movement of the pushing block pushed by the air bag, so that the indentation and scratch are effectively eliminated, the die is particularly suitable for parts with high requirements on surface quality such as mirror surface stainless steel and anodic aluminum oxide alloy, the elastic deformation of the air bag can absorb the impact energy of demoulding instant, and micro cracks caused by sudden stress of materials are avoided.

Description

Four-corner flanging shaping die Technical Field The embodiment of the disclosure relates to the technical field of automobile molds, in particular to a four-corner flanging shaping mold. Background The four-corner flanging shaping die is a special die in the stamping die and is mainly used for flanging forming and shape correction of four corner areas of sheet metal parts, and is commonly used for manufacturing products such as automobile covering parts, household appliance shells and the like. In the field of automobile die manufacturing, particularly in the production of automobile covering parts, the function of the four-corner flanging shaping die is particularly important. Automobile panels such as doors, hoods, trunk lids, and the like often require precise flanging and shaping of the edge portions thereof to achieve good assembly accuracy and appearance quality. However, the conventional four-corner flanging shaping die has some defects in use, when the automobile covering part is subjected to flanging shaping, the automobile covering part needs to be ejected from the lower die through the air cylinder, when the automobile covering part is large, the air cylinder possibly forms an indentation on the surface of the automobile covering part, especially when the automobile covering part with large area or high requirement is processed, so that a plurality of air cylinders are generally required to be installed to push the automobile covering part at the same time, but when the air cylinders are independently controlled, millisecond-level delay exists between four corners and straight sides ejection, so that parts are subjected to uneven shearing force, and distortion deformation is caused.
