Abstract

The invention discloses a rapid mold changing device. The rapid mold changing device comprises a mold base plate for clamping molds, and a pneumatic device which can fix a mold or remove the fixation is arranged on the plate body of the mold base plate. The invention also discloses an injection machine using the rapid mold-changing device, and a use method of the injection machine. According to the rapid mold changing device, the injection machine and the use method of the injection machine, a rapid mold changing process is achieved by an automatic locking mode. In a prior mold changing mode, mold base plate mounting and dismounting time accounts for about 42% of the whole mold changing time. Through use of the injection machine and the rapid mold changing method thereof, the whole mold changing efficiency is improved by more than 40%.

Description

technical field [0001] The invention relates to a mold changing equipment, in particular to a quick mold changing device for an injection molding machine, an injection molding machine using the quick mold changing device and a quick mold changing method for the injection molding machine. Background technique [0002] Injection molding machine is the main equipment for manufacturing compression molding products. When working, it is necessary to assemble and replace the mold used for product molding; at present, the traditional bolt and platen type manpower is used to install and disassemble the mold on the injection molding machine. Operation, since this method is manually installed by the molder during the entire mold changing process, it is limited by the experience, physical strength, and labor time of the molder, and the efficiency of the mold loading process is low. The length of time is difficult to be effectively guaranteed. [0003] At present, the hydraulic mold cla...
