Automatic mould-opening machine for rotary table shoemaking machine

The utility model relates to an automatic mould-opening machine for a rotary table shoemaking machine. The automatic mould-opening machine comprises a machine frame, a mould-lifting mechanism, a mould-opening mechanism, an injection molding head pulling mechanism, a mould-opening lock touching rod and a PLC logic circuit controller. The automatic mould-opening machine imitates operation of a worker, the mould-opening lock touching rod mounted at the upper part of the machine frame touches a mould-opening lock handle through a rotating force of the rotary table shoemaking machine, the mould-opening mechanism mounted in the middle of the machine frame opens a mould, the injection molding head pulling mechanism mounted below the mould-opening mechanism pulls out an injection molding head in the mould after the mould is opened, and then the mould-lifting mechanism mounted above the machine frame lifts and opens a shoe and a shoe mould so as to finish the whole operating process; actions of the mould-lifting mechanism, the mould-opening mechanism and the injection molding head pulling mechanism can be achieved by controlling a compressed air treating unit through the PLC logic circuit controller, so that the automatic mould-opening machine can achieve automatic mould opening, mould lifting and injection molding head pulling, saves time and labors, reduces the labor cost and improves the working efficiency.
