The depanning device of the blank of the cylinder sleeve comprises a main shaft (1) of a casting machine, a flange disc (2), a nut (3), an elastic gasket (4), a bolt (5), a casting mold (6), a paint (7), a blank cylinder sleeve (8), a spring (9), an opened cone-shaped expansion sleeve (10), a cone expansion head (11), a pull rod (12), a spring (13), a front cover (14), a cap (15), an oil cylinder (16), an oil inlet and return pipe (17), a piston (18), a sealing ring (19), an elastic gasket (20), a nut (21), an oil inlet and return pipe (22) and a spiral cooling water tank (23). The flange disc (2) and the casting mold (6) are connected by the bolt (5), the nut (3) and the elastic gasket (4); the opened cone-shaped expansion sleeve (10) and the cone expansion head (11) are arranged at one end of the pull rod (12); and the other end of the pull rod (12) is connected with the piston (18) and installed in the oil cylinder (16).
Description
Technical field
The present invention relates to demoulding device, be specifically related to a kind of knockout unit for cylinder liner blanks.
Background technology
At present; domestic and cylinder jacket manufacturer in the world; when the centre spinning cylinder cover blank; its demoulding device is overhead type; at the main shaft bearing base rear end, hydraulic pressure or mechanical demoulding device are set, behind the cylinder liner blank casting forming; promoted the push rod of casting machine inner hole of spindle by liftout attachment; promote to water the depanning of mold inner cylinder liner blank in the end by push rod, such knock-out gear manufacturing cost is high, and the processing of casting machine inner hole of spindle is very difficult; simultaneously because roof bar demoulding; main shaft and the mould of casting machine have formed through hole, and the rear portion of mould is owing to air enters, and heat-insulating property is poor; caused the end of cylinder liner blank to form the hard phenomenon of material, machining is very difficult.
Summary of the invention
The object of the invention is: a kind of knockout unit for cylinder liner blanks is provided; this demoulding device separates the front end that is arranged on casting machine; behind the cylinder liner blank casting forming; put in the inner chamber of blank by the cone of the hydraulic control head that rises, hydraulic stem retreats, and opens lobe cone ringfeder with cylinder liner blank endoporus tensioner; hydraulic stem continues to retreat the blank cylinder sleeve extracted and waters mold; reduce the processing of knock-out gear and spindle hole, saved manufacturing cost, improved product weight.
The technical scheme that technical solution problem of the present invention adopts is: this knockout unit for cylinder liner blanks comprises the casting machine main shaft, ring flange, nut, the bullet pad, bolt, water mold, coating, the blank cylinder sleeve, spring, open lobe taper ringfeder, the cone head that rises, pull bar, spring, front stifle, and cap, oil cylinder, the oil inlet and oil return pipe, piston, sealing ring, the bullet pad, nut, oil inlet and oil return pipe and spiral bosh, with bolts and nuts and bullet pad mounting flange with water injection molding, be provided with one end of pull bar out lobe taper ringfeder and the cone head that rises, the other end of pull bar connects Piston assembling in oil cylinder.
In the knockout unit for cylinder liner blanks of the present invention, opening mounting spring on the lobe taper ringfeder arc groove.
In the knockout unit for cylinder liner blanks of the present invention, water the mold outer surface and establish the spiral bosh.
In the knockout unit for cylinder liner blanks of the present invention, the casting mold cavity is arranged to blind hole.
During work, stifle before watering the installation of mold front end, then release the button rotated mold filing mould and preheating spray into coating, the casting molten iron, water the mold water cooling, 600 ℃ stop to water injection molding rotation behind casting solidification, are put in the inner chamber of blank by the cone of the hydraulic control head that rises, and hydraulic stem retreats, the cone ringfeder is cylinder liner blank endoporus tensioner, and hydraulic stem continues to retreat the blank cylinder sleeve extracted and waters mold.
The invention has the beneficial effects as follows: simple in structure, safe and reliable, save manufacturing cost, improved production efficiency.
