Carrying mechanism for quick die change

Abstract

The invention discloses a carrying mechanism for quick die change. The carrying mechanism comprises a die carrying platform (1), wherein a plurality of blind holes (2) are formed in the top surface ofthe die carrying platform (1); a steel ball mounting mechanism is arranged in each blind hole (2) and comprises a cylinder (3) as well as a spring (4), a steel ball (5) and an upright post (6) whichare arranged in the cylinder (3), an annular shoulder (7) is arranged in the cylinder (3) and at the upper end part of the cylinder (3), a through hole (8) is formed in the middle of the annular shoulder (7) and communicated with the cylinder (3), a mounting seat (9) is arranged in the cylinder (3) and located at the lower end part of the cylinder (3), the spring (4) is fixed at the top of the mounting seat (9), and the upright post (6) capable of sliding axially along the cylinder (3) is fixed at the top of the spring (4). The carrying mechanism has the following beneficial effects: the structure is compact, sliding friction is changed into rolling friction, die loading and unloading pressure is reduced, labor intensity of a worker is reduced, and die loading and unloading efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of upper and lower mold support mechanisms, in particular to a quick mold change bearing mechanism. Background technique [0002] With the continuous development of stamping technology, the structure of parts is becoming more and more complex, and a set of molds needs to be replaced every time a structure is stamped and formed. In order to facilitate the replacement of molds, it is necessary to use a mold bearing platform with a flat and smooth surface to support the mold. When installing the mold, first place the mold on the mold bearing platform, then push the mold backwards so that the mold is aligned directly under the die under the press, and fix the mold with the pressure plate after it is in place, although the bottom surface of the mold is in contact with the mold bearing The platform is in surface-to-surface contact with low friction, which achieves the purpose of quick mold replacement, but it stil...

When installing the mold, first place the mold on the mold bearing platform, then push the mold backwards so that the mold is aligned directly under the die under the press, and fix the mold with the pressure plate after it is in place, although the bottom surface of the mold is in contact with the mold bearing The platform is in surface-to-surface contact with low friction, which achieves the purpose of quick mold replacement, but still requires a lot of thrust to push the heavy mold back, which increases the labor intensity of workers and reduces the efficiency of the upper and lower molds
