Abstract
A horizontal-parted-mould two-way high pressure molding machine relates to molding equipment of casting technology, which comprises a hydraulic cylinder 1, a piston 2, and a piston rod 3, a plunger piston 4 nested on the piston rod, a firm joint plate 11 arranged on the top of the piston rod, a firm joint support plate 9 arranged on the top of the piston rod, a fixed waste sand frame 10 arranged on the support plate, a squeeze head 14 with multiple contacts , a flat squeeze head 16, a molding box 18, a hydraulic circuit, and a hydraulic cylinder exit pore 5 which is connected with a one-way sequence valve. The utility model has the advantages that a multiple hydraulic cylinder with a piston nested by a plunger piston outside is pushed upward and compressed tightly by the high pressure multiple contacts, then the molding box is placed on the complementary sand frame, the piston is then pushed upward to push the sand mold enter the molding box through the complementary sand frame; thus the sand mixture is compressed by the two-way high pressure, which effectively overcomes the problem that the compactness of the parting surface sand mixture is less than that of the sand filling surface sand mixture; the quality of sand mold is improved. Because the plunger piston can guide and stabilize the piston rod at the same time, the pattern drawing is ensured not to incline. The special shaped convex top contact is used to make the compression and force of the sand mixture more reasonable. Thereby the sand-scraping is avoided, which makes the site clean without sand falling.
Description
Technical field:
The utility model relates to foundry engieering, relates generally to the mo(u)lding equipment of sand casting, is meant a kind of horizontal parting bidirectional high-pressure moulding machine especially.
Background technology:
At present, both at home and abroad in the Foundry Production, because of sand casting production efficiency height, cost is low, flexibility is big, adaptation is wide, technology maturation, be most widely used.The formative method that is used for sand casting has hand moulding and machine molding, and modern machines moulding productivity ratio height, steady quality, labor strength is low, than hand moulding many unrivaled advantages is arranged.Machine molding in using at present has ram-jolt, microseism squeeze mo(u)lding; Pressure, high pressure moulding in low; The moulding of static pressure consolidation; Gas dashes, the air-flow gain adds extrusion moduling or the like, and its pluses and minuses and accommodation are respectively arranged.High pressure moulding is meant the simple squeeze mo(u)lding method of compacting specific pressure more than or equal to 0.7Mpa, and it has the casting quality height, and the foundry goods precision can reach CT7～8 grade, and surface roughness is Ra max=6.3～12.5 μ m, foundry goods metallographic structure densification, and mechanical property improves; Foundry goods precision height can reduce allowance; Reduce labour intensity, boost productivity; Avoided jarring, gas dash etc. formative method hot-tempered sound, pollute and invest drawbacks such as big.So the overall merit high pressure moulding has more superiority than other machine molding, is more suitable for China's national situation.
The high pressure multiple contact moulding machine that high pressure moulding equipment is produced with German KW company is celebrated the most and is the most representative, it has a lifting hydraulic cylinder, its affixed template in piston rod top, fixed model and shelve sandbox on it, the sandbox top is provided with the multiple contact pressure head, lifting after the back-up sand, multiple contact pressure head be the conformal compacting molding sand that floats just, molding then, strike-offs, releases sandbox.It has four defectives: the one,, to touch multiple contact earlier stressed because of lifting case process back-up sand face, what the die joint molding sand was suffered is the power of getting off through the sand transmission from top, so just caused the degree of packing of the sand compaction of die joint less than back-up sand face, the degree of packing occurring is inverted, this is opposite with the formative technology requirement, and this will influence the foundry goods Forming Quality; The 2nd,, need additional complicated molding balanced controls, otherwise will produce withdrawing pattern, influence sand mold complete sum quality; The 3rd,, the contact end face is a flat-top, is mainly vertically and exerts pressure, horizontal, the radial shortcoming of exerting pressure, with each position that influences molding sand evenly tamp, compacting; The 4th,, strike-off and will cause surplus sand to be scattered, need manual recovery, increased workload.
Summary of the invention:
Goal of the invention of the present utility model is existing high pressure multiple contact moulding machine is improved, and a kind of horizontal parting bidirectional high-pressure moulding machine is provided, and it has effectively overcome the many defectives and the deficiency of existing high pressure multiple contact moulding machine, realizes the high-quality moulding.
Above-mentioned purpose can realize by following technique measures, a kind of horizontal parting bidirectional high-pressure moulding machine, comprise hydraulic cylinder 1, cylinder inner carrier 2 and piston rod 3, the affixed template 11 in piston rod top, sandbox 18, multiple contact pressure head 14, pressure head and hydraulic cylinder hydraulic system, described hydraulic cylinder 1 its piston rod 3 overcoat plungers 4, the affixed supporting plate 9 of plunger top, the supporting plate periphery is fixed the strike-off frame 10 that its end face can be placed sandbox 18.Also have one can with the concora crush head 16 of high pressure multiple contact pressure head 14 conversion stations, its bottom surface is provided with a plurality of taper spiculas 17.Oilhole 5 is connected to one way sequence valve 7 on the hydraulic cylinder 1.
The contact 15 of multiple contact pressure head 14 of the present utility model, the shape of its head end are turbination or inversed taper platform shape or the hemispherical of falling.
Advantage of the present utility model is, composite hydraulic cylinder with piston rod overcoat plunger, the affixed template in piston rod top, the affixed supporting plate of plunger top, fixing strike-off frame on the supporting plate, last act is earlier through the compacting of high pressure multiple contact, fall again sandbox is placed on the strike-off frame after rise, lift on the piston sand mold is headed into sandbox by strike-off frame, so make molding sand obtain the bidirectional high-pressure compacting, effectively overcome the die joint sand compaction less than back-up sand face sand compaction problem, improved sand-mould quality.Because of plunger can play guiding, stabilization to piston rod simultaneously, guarantee that molding does not occur tilting, and has guaranteed that sand mold is complete.Adopt the protruding head that contacts of abnormity, make the molding sand compacting stressed more reasonable.Exempted and having strike-off, made the place clean not knockout.
