Description
Technical field
The utility model patent relates to a kind of foundry clay sand sand mold stripper apparatus, especially a kind of stripper apparatus for five width wheel hub sand molds.
Background technology
Casting Metal Melting is smelt meet necessarily required liquid and water enter in casting mold, through cooled and solidified, level process after obtain the technical process of the foundry goods (part or blank) of predetermined shape, size and performance.The fundamental technology of modern mechanical manufacturing industry.The blank of Foundry Production is with low cost, for part that is complex-shaped, that particularly have complicated inner cavity, more can demonstrate its economy; Its adaptability is comparatively wide simultaneously, and has good comprehensive mechanical performance.Modal method for casting production adopts sand casting, and the foundry goods die cavity made with roughing sand, adhesive and other auxiliary materials in Foundry Production is sand mold, and by using, adhesive is different to be divided: clay sand mold, self-hardening resin sand mold, automatic harding glass sand mold.Traditional casting sand mold is divided into two steps when the demoulding: turned by the core that sandbox and bottom thereof are connected with base plate, catches the base plate with core vertically to extract.This method needs to be operated by experienced master craftsman, and not only labour intensity is large, and technical requirement is high, and sand mold is easily out of shape, cause casting dimension accuracy to reduce, easily cause type angle and discontinuity, cause drop, band sand or sand mold damage phenomenon, add manufacturing cost.
Five width wheel hubs are truck hubs that a kind of structure is comparatively complicated, its mechanical property requirements is higher, foundry goods body metallographic requires that uniformity will be got well, mould structure is more complicated also, need to use and make sand mold compared with the furan resin-sand of strong hardness, guarantee the survival rate of moulding, because furane resins, curing agent generally adopt benzene sulfonic acid curing agent, cause cast(ing) surface sulfurizing, cause peeling nodulizing grade on the low side, though adopt antisurlphuizing coating to shield, the cast(ing) surface nodulizing grade that sulfurizing brings can not be eliminated completely low, mechanical performance declines, and casting quality is poor.And furan resin-sand solidify with casting process in can produce strong smell, the eyes of operative employee and respiratory tract are had to larger harm and can not recycle, and cost is higher, because the structure of this product is special, again can not the lower molding sand of working strength; Five width hub molds are in modeling process, and because the groove on each spoke is comparatively dark, when the type of rising, sand mold is easy to fracture, falls soon, and labour intensity is large, time-consuming, and the product qualified rate of sand mold is lower, and manufacturing cost also improves relatively.
Utility model content
For the problems of the prior art, the purpose of this utility model to provide a kind of five width wheel hub clay-bonded sand sand mold moulds, this sand mold mould is with liftout attachment, lower to the requirement of Modeling Material, general use clay-bonded sand can meet requirement of strength, when sand mold is taken out from mould, five projections that liftout attachment can head on sand mold simultaneously up run, and then smoothly by sand mold from mold ejection, this mode of getting sand mold ensure that the overall shape of sand mold, labour intensity is low, technical requirement is not high, and sand mold is not easy distortion, and then casting dimension accuracy is also higher, sand mold is there will not be to rupture, fall fast phenomenon, yield rate is high, working (machining) efficiency is high, be convenient in demoulding laborsaving, save manpower, substantially increase moulding efficiency and be shaped to motility rate and can adopt general clay-bonded sand, reduce production cost.
In order to achieve the above object, the technical solution of the utility model is:
A kind of five width wheel hub clay-bonded sand sand mold moulds, comprise the mould plate of mold, mo(u)ld top half holder template, base, lifting platform, the holder template of bed die and mo(u)ld bottom half mould, mould plate is connected on base by masterplate supporting leg, and by base and masterplate supporting leg positioning supports, it is characterized in that: in the middle part of described mould plate, be provided with sand mold face, described mould plate upper end is provided with mo(u)ld top half holder template, sand mold face relative to the plane of mould plate and mo(u)ld top half holder template in recessed arc, this sand mold face is provided with five sand mold grooves caved in, the middle part in sand mold face is provided with the sand core head of evagination, described five sand mold grooves circumference uniform distribution centered by sand core head, the lifting platform of one deck activity is provided with between mould plate and base, masterplate supporting leg is through lifting platform, under outside dynamic structure effect, lifting platform can move up and down along the direction of masterplate supporting leg, and lifting platform is fixedly installed five jacking blocks and four top case guide rods, jacking block is corresponding with five sand mold groove location, the bottom land of the bottom of sand mold groove is opening shape, lifting platform can drive jacking block pass the bottom land of sand mold groove and move up and down at the bottom of opposed slot.
Preferably, lifting platform heads on mo(u)ld top half holder template by top case guide rod, and this mo(u)ld top half holder template and lifting platform are synchronized with the movement.Also be synchronized with the movement with five jacking blocks, when after sand mold is shaping by the sand mold demoulding time, lifting platform up moves with jacking block and mo(u)ld top half holder template, is jointly ejected in die cavity by sand mold, ejects effective, simple to operate.
Preferably, top case guide rod and the split type setting of mo(u)ld top half holder template, can lift down mo(u)ld top half holder template easily.
Preferably, the sand mold material used in this sand mold mould is green sand, and this structure need not re-use the more expensive furan resin-sand of price, and this structure is less demanding to chiltern intensity, and common clay sand can meet user demand.
Preferably, described jacking block is cuboid jacking block, and the jacking block top surface shape of jacking block is arranged along the bottom land opening shape of sand mold groove, the opening of this jacking block end face and bottom land cooperatively interacts, bottom land being sealed, there will not be crack when carrying out sand mold moulding, guarantee that sand mould structure is perfect.
In addition, locking mechanism can be set on lifting platform, when by sandbox as when mould plate carrying out sand mold moulding, this locking mechanism can prevent lifting platform from moving down under pressure, affects modeling effect.
Compared with prior art, the five width wheel hub clay-bonded sand sand mold mould structures that the utility model provides are unusual, the sand mold mould of traditional fabrication five width wheel hub does not have liftout attachment, the knock-pin that existing liftout attachment is also just single, eject effect bad, also easily make a mess of sand mold, this sand mold liftout attachment is arranged on the bottom of five sand mold grooves, make the sand mold groove bottom land of traditional closed into opening shape, five jacking block actings in conjunction, sand mold block in five sand mold grooves is ejected, simple to operate, efficiency is high, save time, the complete of sand mould structure can be guaranteed simultaneously.
