Description
This equipment belongs to the sand mold moulding machine, especially belongs to gas Impact Molding equipment.
The gas impact molding machine is present a kind of advanced person's mo(u)lding equipment in the world, resembles Germany DE-OS3327822 patent, and No. 85102676 patents of jiangxi Palytechnic Univ. all belong to this class mo(u)lding equipment.There are following three point defects in above equipment: the one, and they adopt a plurality of parallel valve openings to arrange, make the quck-opening valve complex structure, and the accuracy of manufacture requires very high, keeps in repair very difficultly, uses not really reliable; The 2nd, gas acts directly on the molding sand after by flow distribution plate, cause the degree of packing at the sand mold back side not high, therefore need replenish consolidation, perhaps before consolidation, add sand the sand mold back side, behind the consolidation sand mold back side lower molding sand of the degree of packing is removed, this has just increased the complexity of technology; The 3rd, the lifting mechanism of these equipment all adopts large diameter hydraulic jack to finish, and with the supporting oil pump station of oil cylinder, needs investment more than 50,000 yuan.
It is a kind of simple in structure that the purpose of this utility model is to provide, the equipment that cost is low and sand mold compactability is high.
The purpose of this utility model is achieved in that quck-opening valve only adopts one, has increased to amplify the open and close of air valve with the control quck-opening valve in control loop; Adopted multiple contact to cooperate in the shock compaction mechanism, kept sand compaction even with dividing flow cone, flow distribution plate; Lifting mechanism adopts wrist assembly and cylinder, to replace original hydraulic system.
The quck-opening valve of this equipment adopts single hole garden type valve, has increased the amplification air valve and make simple in structurely, easy to manufacture in control loop, uses reliable, easy to maintenance; Adopted multiple contact in the shock compaction mechanism, gas shock multiple contact and make contact do accelerated motion, its kinetic energy is greater than the direct impact of gas to molding sand, not only solved the low problem of the sand mold back side degree of packing, and saved source of the gas, source of the gas can be dropped to 0.3MPa and just can meet the demands by the 0.6MPa of similar original equipment; Lifting mechanism has adopted wrist assembly and cylinder, and is not only simple in structure, reliable, compares with original hydraulic system and reduces cost more than 50,000 yuan.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
Fig. 1 is the profile according to the gas shock compaction moulding machine that the utility model proposes.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete equipment that the utility model proposes.
This equipment comprises quck-opening valve mechanism, three parts of shock compaction mechanism and lifting mechanism.Quck-opening valve mechanism comprises magnetic valve 1, amplifies air valve 2, muffler 3, quck-opening valve 5, gas tank 20.Magnetic valve is a two-position four-way valve, D
g=3/4
11, amplifying air valve is two position three-way valve D
g=50 millimeters, its effect is that moving up and down of quck-opening valve of control reaches closing and opening of quck-opening valve.The volume of gas tank is 1.5M
3, 320 * 8.6 millimeters of the sealing ring φ above the quck-opening valve, 250 millimeters of valve opening diameter phi.Comprise branch flow cone 6, flow distribution plate 7, second diffluence plate 8, guide rod 9, contact 11 in the shock compaction mechanism.Dividing flow cone is a garden shape awl, and cone angle 90 degree are bored highly 120 millimeters, are drilled with the passage of 6 φ 25 on the awl of garden, 20 millimeters apart from flow distribution plate plane of cone bottoms.Flow distribution plate is one thick 160 millimeters a matrix plate, and concave surface is downward, is drilled with the passage of 50 millimeters of 63 φ.The second diffluence plate is thick 35 millimeters iron plate, evenly is drilled with the passage of 30 millimeters of 63 φ above, is drilled with 8 of the passages of 15 millimeters of φ around in each hole, and guide rod is 30 millimeters rod members of φ, and there is boss the bar upper end.Contact is that 63 square iron blocks are closely arranged mutually, and the gap between them is between the 0.2-0.5 millimeter.Lifting mechanism comprises wrist assembly 14 and cylinder 17, supporting plate 24, bearing 25, magnetic valve 15.Wrist assembly is made of a, b, c, d, six identical rod members of e, f and bearing pin 26.Wrist assembly stroke S=220 millimeter, cylinder 17 are that 125 millimeters valve piston 16 diameters are that 300 millimeters big piston 18 constitutes by piston rod 19, diameter.Wrist assembly has specific (special) requirements that two pistons need be set to cylinder.Find out from the mechanical analysis of wrist assembly: when cylinder piston rod moves upward, need very big active force to lift molding sand, sandbox, so it is very big that the diameter of cylinder requires, before having arrived the fast termination of cylinder stroke, effect can reach infinite after the expansion of the first elbow joint ef, and that the active force of the second elbow joint ab and cd also can reach is infinite, if when at this moment running into reaction force, the active force of cylinder is added up entirely and will be caused template, sandbox and equipment destroyed.In order to solve the active force that this contradiction only reduces cylinder, then on big cylinder piston 18, a valve piston 16 is being set again, when cylinder operation begins, big valve piston is all worked, but because the valve piston area is little, active force is also for a short time to be pushed away motionlessly, and at this moment big piston plays a major role; When the near stroke of big piston stopped, it quit work, and continues the work of moving upward by valve piston.
This equipment components is to connect like this.Solenoid control is amplified air valve, amplify the Air Valve Control quck-opening valve, muffler is positioned on and amplifies on the air valve, gas tank is fixedlyed connected with the entablature 22 of this machine frame 21, divide flow cone to be positioned at the quck-opening valve central lower, be fixed on flow distribution plate with four screws, one time flow distribution plate top is connected with entablature, the bottom is connected with the second diffluence plate, contact is suspended on the second diffluence plate by guide rod, each guide rod can axially move in the hole, and guide rod is corresponding with the position of a flow distribution plate pore, so that air-flow is affacted on the contact, wrist assembly ac rod member is connected by bearing pin with supporting plate, the bd rod member is connected with bearing by bearing pin, and bearing is fixed on the sill 23 of framework, and the ef rod member of wrist assembly is connected with the piston rod of cylinder.Valve piston is enclosed within the big piston, the motion of magnetic valve 15 control cylinders.
The course of work of this equipment is as follows: after sandbox 12 has added molding sand, sends in this machine, and magnetic valve 15 energisings at this moment, cylinder operation, piston rod moves upward and promotes the wrist assembly motion and promotion template 13; Sandbox, strike-off frame 10 move upward together.When the molding sand of strike-off frame is run into multiple contact, and drive multiple contact and move up together, when multiple contact contacted with the second diffluence board plane, multiple contact began to compress molding sand, until the plane contact of the last plane of strike-off frame and second diffluence plate and till compressing.At this moment air valve work is amplified in magnetic valve 1 energising, and quck-opening valve air chamber 4 air inlet sources are cut off, and quck-opening valve air chamber and atmosphere are connected, gas emptying by muffler.Pressure in the quck-opening valve air chamber descends rapidly, and quck-opening valve is upwards rapid to be moved and open and the gas of gas tank promotes.Air-flow is discharged from quick opening valve, runs into branch flow cone shunting, impacts on the multiple contact by flow distribution plate and the shunting of second diffluence plate again, makes multiple contact do accelerated motion and compacting molding sand.
