Simple multi-station rapid die changing device

Abstract

The invention discloses a simple multi-station rapid mold changing device. The mold changing device comprises an upper mold base, a lower mold base, guide rails, positioning pin lifting mechanisms andpressing plate jacking and pressing mechanisms; guide columns on the upper mold bases are in sliding fit with guide sleeves on the lower mold bases; the positioning pin lifting mechanisms are locatedon the inner sides, on one end of knobs, of the guide rails, and are used for mold positioning; a set of the guide rails on the lower die base are located on two sides of each lower die holes, and are arranged in a longitudinal mode; the pressing plate jacking and pressing mechanisms are located at the opposite angle positions of the lower die holes, and are connected in a shaft mode between longguide rails and short guide rails. The simple multi-station rapid mold changing device is applied to machines such as a punch press, a press machine and the like so that requirements for replacing molds of products with different specifications can be met, the process of positioning and fixing of single-process molds are accelerated, structure is simple, maintenance is easy, cost of accessories of the whole set of the molds is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a simple multi-station rapid die change device, which is mainly suitable for the rapid change of punch presses, presses and various automatic machines using dies. Background technique [0002] At present, whether it is a forging machine or a stamping machine, it is inevitable to change the mold frequently in its normal production, so the length of the mold replacement time is one of the factors that affect the production efficiency of the machine. However, when the machine tool processes different sheet materials, it needs to use multiple sets of molds; when processing different shapes and structures, it needs to use different molds. On the common mold base, each single process needs to be positioned and fixed. Due to the traditional During the mold assembly process, multiple bolts are often used for positioning. It is time-consuming and laborious to replace the mold, and the speed of mold change is seriously affected, which ca...

However, when the machine tool processes different sheet materials, it needs to use multiple sets of molds; when processing different shapes and structures, it needs to use different molds. On the common mold base, each single process needs to be positioned and fixed. Due to the traditional During the mold assembly process, multiple bolts are often used for positioning. It takes time and effort to replace the mold, and the speed of mold change is seriously affected, which cannot meet the requirements of automatic production.
