Description

Guide post limiting guide mechanism in lower die of die Technical Field The utility model relates to the technical field of dies, in particular to a limiting and guiding mechanism for a guide post in a lower die of a die. Background In recent years, with the increasingly vigorous competition of the automobile market, various automobile manufacturers aim at covering parts and related stamping parts of automobiles in the direction of developing and researching novel automobile types, and the requirements on the covering parts and the related stamping parts are also called as finished parts, so that the requirements on the covering parts and the stamping parts are higher and higher, the finished parts tend to be complicated, high-strength, various and complex in types and unique in shape. The lifting plate for supporting the workpiece is arranged on the lower die holder in the die, and the lifting plate needs to repeatedly move up and down in production, so that the distance accuracy of the lifting plate and the lower die holder in the up and down movement is ensured, a guide post and a limit hook are usually used in a matched mode, but the structure has great influence on the die space, and a floating connecting device with smaller installation space is needed, so that the die space is increased, and the die cost is reduced.
