Abstract
The utility model relates to an air-blowing and lifting hydraulic system of a sprue milling machine, which comprises an air source, an air source treatment device, a pressure gauge, an air-blowing electromagnetic directional valve, a lifting electromagnetic directional valve, silencers, a spacer plug, a throttle valve, a one-way valve, one-way throttle valves, hoses, a cylinder and an air-blowing nozzle. The lower end of a piston rod of a lifting cylinder is connected with the air-blowing nozzle controlled by the air-blowing electromagnetic directional valve, and the throttle valve, the one-way valve and one of the hoses are mounted between the air-blowing electromagnetic directional valve and the air-blowing nozzle. The lifting electromagnetic directional valve controls the lifting of the cylinder, and the one-way throttle valves and the other of the hoses are mounted between the lifting electromagnetic directional valve and the cylinder. The air-blowing and lifting hydraulic system of the sprue milling machine is compact in structure and small in occupied area since the two electromagnetic directional valves, the two silencers and the spacer plug are integrated on one valve block, and is simple and convenient in operation and good in cleaning effect due to the fact that the air-blowing nozzle can move vertically along with the cylinder and floating sand which is milled can be blown and cleaned completely.
Description
Technical field
The utility model belongs to casting field, relates to full-automatic flask molding line, especially a kind of cast gate machine air blowing lifting hydraulic system of milling.
Background technology
In full-automatic moulding line production practices, in order to finish cast work, the processing of cast gate is absolutely necessary.After having made sand mold, mill the moulding line of gating practice separately, need a cover and can sweep clean system floating sand blast.But existing blow device or can not move up and down along with the lifting of milling cutter causes the sand mold cast gate to go out to purge unclean, or structure is not compact, and floor space is big, is not easy to operation and maintenance, and cost is also high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of easy and simple to handle, compact conformation, cleaning clean mill cast gate machine air blowing lifting hydraulic system.
The utility model realizes that the technical scheme of purpose is as follows:
A kind of cast gate machine air blowing lifting hydraulic system of milling, comprise source of the gas, air supply processing equipment, Pressure gauge, air blowing and lifting solenoid directional control valve, muffler, batching pig, choke valve, check valve, one-way throttle valve, flexible pipe, cylinder, blowing nozzle, the piston-rod lower end of lift cylinder connects a blowing nozzle by the control of air blowing solenoid directional control valve, between this air blowing solenoid directional control valve and the blowing nozzle choke valve, check valve and flexible pipe is installed also; The lifting of lifting solenoid directional control valve control cylinder also is equipped with one-way throttle valve and flexible pipe between this magnetic valve and the cylinder.
And, being connected with an air supply processing equipment at the air inlet position of source of the gas, this air supply processing equipment is made of tee ball valve, oil water separator, pressure-reducing valve and oil sprayer.
And, be provided with a batching pig between two gas circuits of described air blowing and lifting solenoid directional control valve.
Advantage of the present utility model and good effect are:
Originally mill cast gate machine air blowing lifting hydraulic system two solenoid directional control valves, two mufflers and batching pig are concentrated on above the valve piece, compact conformation, floor space is little, blowing nozzle can move up and down along with cylinder, to mill the floating sand blast that gets off and sweep totally, easy and simple to handle, cleaning effect is good.
Description of drawings
Fig. 1 is the structure connection diagram of the utility model lifting hydraulic system.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of cast gate machine air blowing lifting hydraulic system of milling, form by source of the gas 101, air supply processing equipment 102, Pressure gauge 103, air blowing and lifting solenoid directional control valve 107,108, muffler 105,106, batching pig 104, choke valve 109, check valve 110, one-way throttle valve 114,115, flexible pipe 111,112, cylinder 116, blowing nozzle 113 etc., source of the gas 101 links to each other with air supply processing equipment 102, and this air supply processing equipment is made of tee ball valve, oil water separator, pressure-reducing valve and oil sprayer; Pipeline through oil sprayer connects lifting solenoid directional control valve 108, does not have the pipeline through oil sprayer to connect air blowing solenoid directional control valve 107.107,108 and two mufflers 105,106 of two solenoid directional control valves and batching pig 104 are installed on the same valve piece.The outlet of air blowing solenoid directional control valve 107 links to each other with the blowing nozzle 113 that is fixed on the lever front end, and the centre is provided with choke valve 109, check valve 110, flexible pipe 111; The outlet of lifting solenoid directional control valve 108 links to each other with the upper and lower cavity of cylinder 116 respectively, and the centre is provided with flexible pipe 112 and one-way throttle valve 114,115.
Operation principle of the present utility model is:
System must not when electricity, and the gas of handling through air supply processing equipment enters lower chamber of air cylinder by lifting solenoid directional control valve 108, and cylinder can not blown and remained on raised position this moment.
Valve is blown and the lifting of cylinder is controlled two gas circuit mutually noninterferes by two solenoid directional control valves 107,108 respectively.When air blowing solenoid directional control valve 107 when electric, the gas after source of the gas is handled begins to blow without oil sprayer, and is adjusted by choke valve.When lifting solenoid directional control valve 108 when electric, the gas after source of the gas is handled enters into upper chamber of air cylinder through oil sprayer, and cylinder is descended.The lifting of cylinder is outlet throttling speed governing by two one-way throttle valve regulation.
