Quick hoisting type mold changing trolley and mold changing method thereof

Abstract

The invention discloses a quick hoisting type mold changing trolley and a mold changing method thereof. The quick hoisting type mold changing trolley comprises a trolley body, wherein the trolley body comprises a bearing surface and an underbed; the trolley body is provided with an electrical control system for controlling a mold changing process; mounting seats are arranged at two ends of the trolley body; a lifting mechanism is connected between each mounting seat and the trolley body; each mounting seat is arranged in a separate manner, and comprises an upper part and a lower part; a first horizontal translation mechanism is connected between each upper part and the corresponding lower part; each upper part is provided with a mold shifting arm; and a second horizontal translation mechanism is connected between each mold shifting arm and the corresponding upper part. Compared with the prior art, the quick hoisting type mold changing trolley has the beneficial effects that a mold is lifted up through the lifting mechanisms at first, and then moves to the trolley through the translation mechanisms, in a whole process, the bottom surface of the mold does not rub a working table and the trolley, the mold changing process is stable, mold changing time is saved, and mold changing efficiency is improved.

Description

technical field [0001] The invention belongs to supporting equipment for mold changing operations of stamping machines, and relates to a fast lifting type mold changing trolley and a mold changing method thereof. Background technique [0002] In the current plastics industry, when changing molds, only cranes and manpower can be used to change molds. When the crane is changing the mould, it is prone to illegal operations such as crooked pulling and slanting, and the wire rope is also prone to damage the machine tool equipment during the pulling process. On the other hand, because the pulling distance is difficult to control, the operator operates completely by his own feeling, which is very easy to cause accidents where the mold slips to the ground and hurts people due to improper force. In addition, moving large molds manually is time-consuming and labor-intensive. [0003] Chinese patent, application number 201220164757.0, discloses a multi-directional mold changing troll...

Problems solved by technology

[0005] But its disadvantage is that the transmission structure is complex

[0008] But its disadvantage is: when the mold leaves the workbench, it is forced to the mold changing trolley, which is easy to cause wear to the mold
