Abstract

The utility model relates to a hydraulic mould stripper which can strip the ingot mould cast from the mould by using the technology of the hydraulic transmission. The utility model comprises a mould stripping mechanism and a hydraulic transmission control system used for providing pressure oil for the mould stripper and controlling the mould stripping. The inner side of the oil cylinder body of the mould stripping mechanism is composed of an upper oil cylinder, a lower oil cylinder, an oil cylinder piston, and a piston rod. The lower end of the piston rod is a working head, and a lifting ring, a lifting eye, and a suspended type mould hook are arranged on the outer side of the oil cylinder body. The utility model can conveniently do the mould stripping on the steel ingot mould. The utility model has the advantages of simple structure, reasonable structure, flexible operation, lower labor intensity, and high production efficiency.

Description

Hydraulic ingot stripper

The utility model relates to a kind of device that adopts hydraulic transmission technology to make ingot mould foundry goods and mould separating, is specially the hydraulic ejection machine.

The Ferrous Metallurgy casting industry generally adopts monoblock type die casting ingot mould at present.Behind the product casting, with suspender foundry goods is hung up together with mould, make the foundry goods demoulding with the mode of beaing.The foundry goods demoulding difficulty manufacturing schedule is restricted, and stripping means is improper, and former sand mold is subject to destruction, and the molding sand consumption is big, and the labour intensity height increases production cost.Chinese patent (CN2049569U) once disclosed a kind of steel-making ingot casting demoulding unit, and it comprises handling and two systems of the demoulding.Lifting system is formed boom hoisting by a plurality of hydraulic machineries, and it can lift by crane several ingot moulds simultaneously, adopts the stripping means of ingot mould bottom backform, utilizes switching mechanism simultaneously, can pour out steel ingot easily from ingot mould.This utility model mechanization degree height can be continuous, large batch ofly carries out the steel ingot demoulding, but owing to adopt bottom backform and upset reverse mould operation, when being applied to the stripping process of cast steel ingot mould, still can destroy the sand mold of ingot mould mould, and complex structural designs.

The purpose of this utility model provides a kind of hydraulic ejection machine simple in structure; it both can guarantee to realize smoothly the disengaging of foundry goods and mould, alleviated labor intensity of operating personnel, helped improving the utilization rate of molding sand again; reduce production costs, and provide condition for safety in production.

The utility model is made up of mould emptier and hydraulic transmission control system.Mould emptier is made of upper cylinder, following oil cylinder, working head, cylinder body, oil cylinder piston, piston rod, suspension ring, hanger, suspension type mould drop hanger and high pressure rubber hose etc.To upper cylinder input pressure oil, discharge the oil of oil cylinder down by high pressure rubber hose simultaneously, working head stretches out; When downward oil cylinder input pressure oil, discharge the oil of upper cylinder simultaneously, the working head withdrawal.The top of cylinder body is provided with suspension ring for the boom hoisting lifting.On the hanger of both sides, cylinder body bottom, respectively have one group of groove, be used for fixing suspension type mould drop hanger, and make ingot stripper be applicable to the mold releasability of different size.The piston rod of oil cylinder and oil cylinder piston connect; the bottom of piston rod is a working head, and piston rod is that thread connects with working head, and working head is cone body; to guarantee tapered core iron when mould emptier and mould to timing, operating pressure is along the axial pressure of mould.Suspension type mould hanger can make the mould sling keep parallel with ingot stripper and the center is symmetrical, and can keep the rigid attachment of working head cylinder body and mould when tapered core iron is exerted pressure.

Hydraulic transmission control system provides pressure oil by high pressure rubber hose to mould emptier; and control the flexible of mould emptier working head, it is made up of motor, closed oil tank, screen filter, oil pump, one way stop peturn valve, solenoid directional control valve, Pressure gauge, overflow valve, high pressure rubber hose etc.By the motor drives oil pump, oil passes through oil cylinder discharge pressure oil up and down such as one way stop peturn valve, overflow valve and high pressure rubber hose through oil pump.The pressure of oil is shown by oil pressure gauge in the oil circuit, and by being arranged on the overflow valve adjustment in the oil circuit.Solenoid directional control valve is an electric control element of the present utility model, and it can change the flow direction of pressure oil in the oil circuit, and control mould emptier working head is flexible.High pressure rubber hose connects with upper and lower oil cylinder respectively, and high pressure rubber hose is the netted rubber hose of a kind of multiple layer metal, can bear elevated pressures, and is suitable for mould emptier mobile use in a big way.

In conjunction with the accompanying

drawings

1,2 pairs of the utility model of accompanying drawing and method of operating thereof are described further:

Fig. 1 is the principle schematic of the utility model hydraulic transmission control system.

Fig. 2 is the front view of the utility model mould emptier 10.

Wherein:

1-motor 2-closed oil tank 3-screen filter 4-oil pump 5-one way stop peturn valve 6-solenoid directional control valve 7-Pressure gauge 8-overflow valve 9-high pressure rubber hose 10-ingot stripper 11(1)-upper cylinder 11(2)-the tapered core iron 20-of lower oil cylinder 12-cylinder body 13-oil cylinder piston 14-piston rod 15-suspension ring 16-hanger 17-working head 18-suspension type mould drop hanger 19-mould 21-sand mold 22-ingot mould 23-core ingot

Mould emptier 10 of the present utility model is by upper cylinder 11(1) and following oil cylinder 11(2) cylinder body 12 formed, be built-in with oil cylinder piston 13 and piston rod 14 and be coupled to each other at cylinder body 12, the lower end of piston rod 14 is a working head 17, working head 17 is cone body, piston rod connects for the screw spinner with working head, high pressure rubber hose 9 is connected upper cylinder 11(1 respectively) and following oil cylinder 11(2) and link with hydraulic transmission control system, at upper cylinder 11(1) the top be provided with suspension ring 15, both sides, bottom at cylinder body 12 are fixed with hanger 16, on the hanger 16 of symmetry, respectively have one group of groove, according to the size of mould, suspension type mould drop hanger 18 can place in the suitable groove of hanger 16; Hydraulic transmission control system is made up of motor 1, closed oil tank 2, screen filter 3, oil pump 4, one way stop peturn valve 5, solenoid directional control valve 6, Pressure gauge 7, overflow valve 8 etc.

When the utility model uses, available overhead traveling crane mould emptier 10 is sling and move to mould 20 directly over, suspension type mould drop hanger 18 is hung mould and is kept working head 17 to be on the center of tapered core iron 19, then mould 20 is hung ground simultaneously.Starting motor 1, oil pump 4 is started working, and presses the control push button of solenoid directional control valve 6, and working head 17 stretches out, and can implement the demoulding, after the sand mold 21 of ingot mould 22 and mould breaks away from, makes working head 17 withdrawals in order to the next demoulding.
