Automatic mold drawing machine for wheel casting mold

Abstract

The invention discloses an automatic mold drawing machine for a wheel casting mold. The automatic mold drawing machine comprises a mold drawing mechanism and a mold mounting seat, wherein the mold drawing mechanism comprises a base; an oil cylinder is fixed at the center of the base; a top plate is fixed on a piston rod of the oil cylinder; a plurality of adjustment bolts are fixed on the upper end face of the top plate; a plurality of guide columns are inserted into the top plate and are fixed on the base; a plurality of pull hooks are arranged on the outer side of the top plate and are hinged to the base through hinge seats and hinge shafts; the die mounting seat comprises a base plate; a screw rod is fixed on the base plate; a plurality of guide sleeves are fixed on the base plate, and mandrils are inserted into the guide sleeves and correspond to the adjustment bolts on the drawing mechanism. The automatic mold drawing machine is designed for an upper casting mold of a wheel hub, so that manual demolding by a worker is replaced, and the problems of mandril locking and trouble in detaching are solved; therefore, the demolding speed is increased, injury to the mold is reduced, the labor intensity of the worker is alleviated, and the production efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of auxiliary devices for casting aluminum equipment, and more specifically relates to an automatic mold lifting machine for wheel casting moulds. Background technique: [0002] At present, the wheel hub is generally formed by casting, and after the casting mold completes a production cycle, it needs to be fully maintained and repaired. It is necessary to disassemble the screw, top and bottom plates of the upper mold and other important links. The mold installation of the existing upper mold Seat such as figure 1 As shown, it is inserted into the screw rod 21 of the mold mounting seat, but due to the influence of high temperature and high pressure, the ejector pin is generally stuck, and the disassembly of the mold requires all the screws and ejector pins to be separated, or the mold must be manually clamped with an iron bar. The top plate needs to be knocked continuously to complete the disassembly, and th...
