Abstract
The utility model relates to a sand chilled and drawing machine, which is a device of hardening sand mould and drawing compound processes used for casting production. The utility model is particularly suitable for the flow processes and the line production of the chilled and drawing sand mould for fine castings. A carbon dioxide chamber arranged at the lower part of the piston rod of a head section cylinder is driven down by the piston rod of the head section cylinder, the gas is blown from a pore arranged on a bottom surface to blow a hard sand mould box and the sand mould in a mould, the sand mould box is pushed up by a lower push rod mechanism, and a produced hard mould can be obtained. The utility model can cast fine parts, has high efficiency, and the blowing gas can be saved.
Description
The utility model relates to the device of castings production with hardening sand mold and molding compound working procedure, be specially adapted to fine cast of Fe-Mn chill, play the model sand mold continuous productive process or become line production.
Producing sand mold with the gas hardening method in foundry industry generally adopts.Most waterglass and the resins of adopting of moulding sand binder, with carbon dioxide or triethylamine, sulfur dioxide gas is blow molded into hard sand mold.Poisonous from the cost of binding agent and gas, have excitant to consider still to make binding agent on general the production with carbon dioxide and waterglass except producing high-precision foundry goods.
The existing carbon dioxide of using blows the sand mold technology that hard water glass is made binding agent, is divided into two procedures and carries out, two two.The molding of system type elder generation, hard moulding is blown with carbon dioxide in the back.Molding and chillly on two equipment, carry out.Adopt the vibration molding during molding mostly, lost a part of precision, can only make the cast product of the following precision of CT7.Blowing computer hardware is the case and the hardening cabinet of simple structure, and carbon dioxide was chill for up to tens of minutes.Also on an equipment, do not finish the equipment that earlier chill back molding makes the hard sand mold of fine cast of Fe-Mn now.
The purpose of this utility model is to overcome the deficiencies in the prior art part, proposes a kind ofly can finish the chill sand mold of carbon dioxide on an equipment, steadily works the device that is molded as the higher hard sand mold of precision then.
The purpose of this utility model can reach by following measure:
The utility model structure mainly comprises, the gripping mechanism on fuselage, head cylinder, support, workbench, workpiece sand mould box, template, the workbench, push rod elevating mechanism and air chamber, source of the gas, pipeline such as cut down at composition.The sand mold that workpiece sand mould box and template are contained when chill is by the air chamber bottom surface of cylinder piston rod lower end elder generation consolidation, the air chamber bottom surface is pressed on the periphery of molding sand case upper edge, sand mold is sealed in the middle of air chamber, sand mould box and the template, and the air chamber carbon dioxide blows hard sand mold by the air chamber hole, finishes chill step.Move on the air chamber, chucking sand mould box and template are moved on the push rod and are ejected sand mould box, can take out the hard sand mold after the molding, have finished mold process.
The purpose of this utility model can also reach by following measure:
1) the venting hole of air chamber bottom surface is barrier shape hole.
2) air chamber bottom surface barrier shape hole spacing is less than the molding sand granularity.
3) air chamber is the tabular air chamber of cavity.
4) it is gradient that sand mould box is frame shape inner rim.
5) the push rod elevating mechanism is linkage or hydraulic pressure, pneumatic cylinder mechanism.
Accompanying drawing is the chill pattern drawing machine structure principle chart of sand mold.
Description of drawings: 1 support, 2 push rod elevating mechanisms, 3 handwheels, 4 push rods, 5 gripping mechanisms, 6 templates, 7 sand mould boxes, 8 venting holes, 9 air chambers, 10 fuselages, 11 carbon dioxide tracheaes, 12 head cylinders, 13 cylinder hydraulic pressure or pneumatic tubes, 14 carbon dioxide air sources, 15 head cylinder hydraulic pressure or pneumatic supplies, 16 pistons; 17 piston rods, 18 cut down door 1,19 cuts down door 2,20 workbench, 21 sand molds, 22 cut down door 3.
Example shown in the utility model is incited somebody to action in conjunction with the accompanying drawings is described in further detail:
From accompanying drawing its structure as can be seen, support (1) is gone up and is linked curved boom shape fuselage (10), there is tubular head cylinder (12) fuselage (10) top, piston (6) is arranged in the head cylinder (12), piston rod (17) lower end under the piston (16) has a bottom surface to be the tabular air chamber (9) on plane, air chamber (9) bottom surface has barrier shape venting hole (8), head cylinder (12) is connected with pneumatic tube (13) and cuts down a 1(18) cut down a 2(19), and link to each other with air compressor pneumatic supply (15).Be that workbench (20) workbench can be the plane between air chamber (9) and the support (1), can also establish many group rollers on the workbench (20), place sand mould box (7) and template (6) on workbench (20) or the roller.On the support (1) of workbench (20) below, be provided with the push rod elevating mechanism (2) of top, be depicted as the connecting rod elevating mechanism (2) of band handwheel (3) leading screw as the accompanying drawing example with four push rods (4).
When sand mould box (7) and template (6) workpiece of containing sand mold (21), put well when workbench (20) position, compressed air is from cut down the 1(18 of pneumatic supply (15) through opening), pneumatic tube (13), enter head cylinder (12), the air chamber (9) that piston (16) in the head cylinder (12) drives piston rod (17) lower end moves down, air chamber (9) bottom surface is pressed on the periphery of sand mould box (7) upper edge, solid sand mold (21), open simultaneously and cut down a 2(19), make carbon dioxide from carbon dioxide air source (14) through carbon dioxide tracheae (11), enter air chamber (9) back and enter sand mold (21) from air chamber (9) barrier shape venting hole (8) and make it sclerosis.Close then and cut down a 2(19).Compressed air makes piston (16) go up the moving piston rod (17) of shipper pole again, air chamber moves on (9), finishes chill step.Gripping mechanism (5) tightens sand mould box (7) and template (6) automatically then, shake handwheel (3), rotary screw rod makes on the push rod (4) on the push rod elevating mechanism and moves, pass the hole on workbench (20) and the template (6), sand mould box (7) is gone up the top, separate the sand mold (21) after blowing firmly, can take out chill good hard sand mold (21).Be noted that also this equipment can blow hard sand mold (21) from template (6) face.
The utility model has the following advantages compared to existing technology:
1. chill, the molding of sand mold can at a station, be finished on the equipment. Saving of labor, the efficient that saves time height. Per hour plastic 100～120 of outputs.
2. adopt the friction molding, guaranteed the casting mold precision, foundry goods can reach CT7 level dimensional accuracy.
Carbon dioxide air pressure, flow, controlled, prevent the over-blowing phenomenon.
4. than there being mutually technology to economize carbon dioxide about 50%.
