Abstract
The utility model relates to a molding of sand mould nodular cast iron spare is with abaculus formula dysmorphism chill mechanism, dysmorphism chill mechanism includes a plurality of arc chill piece and bar chill piece, arc chill piece and bar chill piece highly the same, the width is also the same, the cross section of chill piece is the rectangle be provided with the boss more than two on to the side of interior the making plausible of arc chill piece and on the length direction side of bar chill piece, the length of boss is highly the same with arc chill piece and bar chill piece, the height of boss is fourth to the two -thirds of the width of arc chill piece and bar chill piece, the inlaying power in the molding sand and the not slippage of chill when the shape of this structure will be guaranteed to increase the molding, special -shaped chill mechanism through the concatenation circularizes guarantees the cooling rate after the pouring.
Description
Technical field
The utility model relates to a kind of sand mold nodular iron casting moulding abaculus formula abnormity chill mechanism, belongs to ironcasting sand casting auxiliary member field.
Background technology
The Main Function of chill coordinates the solidification sequence controlling foundry goods, the setting rate accelerating foundry goods with running gate system and rising head, and energy crystal grain thinning tissue, improves the mechanical property of foundry goods simultaneously; Reduce Riser Dimensions, improve product yield.Apply widely in nodular iron casting sand casting.
Traditional chill is made up of cast iron.Due to chill when moulding be potting in type, core sand, its shape matching is simple, especially easily slippage, causes sand mold to be scrapped time serious.
Utility model content
The purpose of this utility model be exactly to propose a kind of when preventing moulding chill produce the organization plan of slippage, reduce the casting mold caused thus and scrap.
The utility model solves the technical scheme that its technical problem adopts:
A kind of sand mold nodular iron casting moulding abaculus formula abnormity chill mechanism, described special-shaped chill mechanism comprises several arc frozen iron blocks and bar shaped frozen iron blocks, arc frozen iron blocks is identical with the height of bar shaped frozen iron blocks, width is also identical, the cross section of described frozen iron blocks is rectangle, plural boss is provided with on the inner circle side of described arc frozen iron blocks and on the length direction side of bar shaped frozen iron blocks, the length of described boss is identical with the height of arc frozen iron blocks and bar shaped frozen iron blocks, the height of described boss is 2/1 to three/4ths of the width of arc frozen iron blocks and bar shaped frozen iron blocks.
As further innovation of the present utility model, be provided with the projection of a taper in the wherein side of described arc frozen iron blocks and bar shaped frozen iron blocks, be provided with a groove corresponding with projection at opposite side.
As further innovation of the present utility model, described boss and arc frozen iron blocks, bar shaped frozen iron blocks are integrated cast structure.
As further innovation of the present utility model, described arc frozen iron blocks, bar shaped frozen iron blocks are inoculation cast iron HT300 material.
As further innovation of the present utility model, the contact surface of described arc frozen iron blocks, bar shaped frozen iron blocks and molding sand is that porous cheats shape.
The beneficial effects of the utility model are:
1, by a kind of abaculus formula abnormity chill of cast iron quality, global shape is arc or bar shaped, and internal diameter and external diameter are determined according to concrete foundry goods arc surface, and at external diameter side design two or more boss structure, be highly 2/3 of chill body, width is identical with body.The power of inlaying in molding sand of chill when the shape of this structure will ensure to increase moulding and not slippage, by being spliced into the special-shaped chill mechanism of annular, ensure the cooling velocity after cast.
2, the use of projection and groove, the fastening force between the power of inlaying of chill in sand mold or special-shaped chill can be improved, chill proportion is large compared with resin sand, so chill is easy to because inertia makes sand mold deform, the situation of the sand mold distortion that projection and groove also can prevent chill local offset from causing.
3, integrally casting structure can improve intensity, prevents boss from peeling off.
4, the specific surface that chill contacts with molding sand is made porous and is cheated shape, also can make porous dress by having built not swabbing, improving the frictional force between chill and sand mold, improving stability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structure chart of arc chill;
Fig. 2 is the structure chart of bar shaped chill;
Figure comprises: arc frozen iron blocks 1, bar shaped frozen iron blocks 2, boss 3, projection 4, groove 5.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, the utility model is a kind of sand mold nodular iron casting moulding abaculus formula abnormity chill mechanism, it mainly comprises arc frozen iron blocks 1 and bar shaped frozen iron blocks 2, arc frozen iron blocks 1 and bar shaped frozen iron blocks 2 all adopt wooden model, moulding is carried out by furan resin-sand, select the high strength inoculation cast iron batching with the long property of excellent anti-oxidant and antibiosis, electro-smelting, adopt composite long-acting to breed the method adding instant inoculation to breed molten iron, ensure that the metallographic structure of material and intensity index meet the demands;
Arc frozen iron blocks 1 and bar shaped frozen iron blocks 2 are provided with two boss 3, wherein the boss 3 of arc frozen iron blocks 1 is arranged on arc inner headed face, bar shaped frozen iron blocks 2 is arranged on the side wall surface of length direction, the height of boss 3 is identical with the height of arc frozen iron blocks 1, bar shaped frozen iron blocks 2, its width be highly for arc frozen iron blocks 1, bar shaped frozen iron blocks 2 width 2/3;
Be provided with the projection 4 of a taper at length direction one side end of arc frozen iron blocks 1 and bar shaped frozen iron blocks 2, end side is provided with the groove 5 corresponding with projection 4;
After having cast, shot-peening is carried out to arc frozen iron blocks 1 and bar shaped frozen iron blocks 2 performance, obtain the hollow surface of non-oxidation layer;
Spliced by projection 4 and groove 5 between arc frozen iron blocks 1 and bar shaped frozen iron blocks 2, be embedded in sand mold simultaneously, ensured the cooling velocity of foundry goods by frozen iron blocks;
Boss 3 can ensure the bed knife between frozen iron blocks and sand mold, prevents frozen iron blocks from skew occurring or comes off.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
