Description
Technical field
The utility model relates to a kind of setting turning device, and particularly turning device erect by the perpendicular sand mold that waters of the horizontal type of a kind of foundry goods, belongs to casting field.
Background technology
Foundry goods is when moulding by casting, due to the structure of product and the difference of field of employment, to foundry goods, there is special requirement, the particularly cast product of some bearing loads, require higher to the castability of foundry goods, some product in use can bear various load, plays the effect of frame member, and therefore its material material, inherent quality are most important to its serviceability.Output shaft housing is exactly the Typical Representative of this series products, it is the carrying housing of all kinds of wind-powered electricity generation, large-scale agricultural equipment mechanical transmission component output shaft, support and contain various driving parts, as gear, axle, bearing etc., output shaft housing enables them keep normal movement relation and kinematic accuracy.In the prior art, output shaft housing in the fabrication process, utilization be the cast shaping process of horizontal sculpting method and three somatotype three-cavity moulding modes.
The right view that the cross-sectional view that Fig. 6 is output shaft shell product, Fig. 7 are output shaft shell products, output shaft housing is the round table-like tube-in-tube structure of tapering, periphery is recess circular arc, wherein, 101 is large nose circle, 102 is little nose circle, nose circle protrudes to outer peripheral side, in Flange-shaped Parts, two outer shaft ends certificates are provided with this flange-like structure, fixing for output shaft housing 100, and output shaft housing 100 inside is provided with through hole, multiple ring-type inner ring is provided with, as the support portion of gear, axle or bearing in the middle of through hole.
Fig. 8 is the sand mold patrix plan structure schematic diagram of horizontal sculpting method, Fig. 9 is the right TV structure schematic diagram of sand mold patrix of horizontal sculpting method, Figure 10 is the sand mold counterdie plan structure schematic diagram of horizontal sculpting method, Figure 11 is the right TV structure schematic diagram of sand mold counterdie of horizontal sculpting method, wherein, 301 is cast gate one, 302 is cross gate one, 303 is rising head one, two rising heads 1 are provided with in the sand mold that this mould is formed, 304 is cope match plate one, 305 is mould board one, molten metal liquid from cast gate 1 through cross gate 302, ingate 306 enters in product cavity, moulding by casting.
Figure 12 is the side-looking structural representation of three somatotype three-cavity moulding modes, in this fashion, need to utilize three moulds to form three sandboxes respectively, three sandboxes are respectively top box 1, raising middle flask 1, nowel 1, castings after the superposition of three sandboxes, wherein, 601 be cast gate two, 603 is rising head two, molten metal liquid enters product cavity from cast gate 2 601 through cross gate, ingate, moulding by casting.
These two kinds of moulding by casting modes, in the moulding by casting process of reality, all have respective shortcoming, its concrete structure and subject matter as follows:
Horizontal moulding mould assembly mode is traditional casting pouring forming method, under level, namely utilize mould form running castings or claim sand mold, the mould assembling of sand mold up and down after utilizing mould molding again under level, from the cast gate upper metallic solution of vertical direction, foundry goods is formed after cooling, in this moulding by casting mode, sprue is consistent with the direction of riser passage, the mould assembling composition surface of all vertical and top box, nowel.
Output shaft housing adopts horizontal moulding mould assembly mode, and the shortcoming of horizontal moulding mould assembly mode is:
1, pour into a mould ingate position in the centre position of horizontal moulding mould assembly mode, static pressure is low, need arrange high riser feeding, and such Product Process yield rate is lower, and production cost price is high;
2, at the position, top of product, be easy to occur shrinkage porosity defect of contraction cavity, position, top is mainly in the place of two head flanges, and this place is generally the place of boring tapping, and shrinkage porosity defect of contraction cavity causes boring tapping failure or installing hole leakage of oil, and then product rejection.
Output shaft housing three somatotype three-cavity moulding mode is at above-mentioned horizontal moulding mould assembly, on the basis of casting on flat method, increase a sandbox again as mid-part, during cast, the two ends of mid-part are superimposed respectively and between upper lower box, pour into a mould, the precision that three somatotype three casees pouring types need making three moulds, three sand molds easily ensure foundry goods, and can reduced proper motion technique.
The shortcoming that three somatotype three-cavity moulding modes exist is:
1, adopt the method due to three moulding of three somatotypes, cannot realize do mechanization operation, production efficiency is low;
2, another shortcoming that artificial model is produced is that the casting mold degree of packing is low and be difficult to stable and consistent, and so not only cast product surface smoothness is low, and makes a concession due to the low casting mold that causes of the casting mold degree of packing, and shrinkage porosite rarefaction defect easily appears in product.
The common feature of above-mentioned two kinds of manufactures is, sprue with and mutually vertical between riser passage with sandbox mould assembling face, easily cause the shrinkage cavity and porosity defect of product end surface, increase the processing scrappage in end face silk hole etc.
Due in pouring forming technology in above-mentioned two, all there is respective shortcoming, how to prevent shrinkage cavity shrinkage porosity problem, improve product percent of pass, improve mould strength and stability, uniformity, the fineness of product appearance, the problems realizing must solving in mechanization production, in long-term production, have developed and ingate is set from flange side, shrinkage cavity shrinkage porosity problem can be avoided, improve static pressure, horizontal type is perpendicular waters method owing to can avoid above-mentioned defect, become the best mode in product manufacturing, but, because sand mold gravity is large, be not easy to move, moving sometimes due to sand mold, sand mold can be caused to damage in case the phenomenons such as sand mold, usually do over again, how to address this problem is the problem that technical staff pays close attention to always.
Summary of the invention
Low for fineness in horizontal moulding mould assembly mode and three somatotypes, three sculpting methods, product yield is lower, production cost price height two flange portion shrinkage porosity defect of contraction cavity causes boring tapping failure or installing hole leakage of oil, and then product rejection, the poor stability of product, and be not easy to realize the problems such as do mechanization operation, under level, sand mold is not easy problems such as erecting, the utility model provides the perpendicular sand mold that waters of the horizontal type of a kind of foundry goods to erect turning device, its objective is to reduce product casting flaw, improve the castability of product, improve the compactness of product surface fineness and product, solve the upset difficult problem of sandbox, reduce costs, realize do mechanization operation.
