Description
Technical field
The invention belongs to casting field, specifically, relate in particular to a kind of casting method of flywheel.
Background technology
Flywheel is widely used in automotive field, the present mode of production of flywheel adopts casting more, and common forging type is as described below, that is: adopt damp husky metal pattern to carry out moulding, the system of risers of casting is arranged cast gate, rising head routinely, and the defect of this forging type is that energy consumption is large, when useless work is useless, molten iron utilization rate is too low, and casting flaw is more, as burning into sand, slag inclusion, pore, loose.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of casting method of efficient, flywheel that cost is low, and solves the casting flaws such as pore that conventional cast method exists, slag inclusion.
Technical scheme of the present invention is as follows: a kind of casting method of flywheel, and its processing step is as follows:
Arenaceous shell in a, system: make on a core shooter, thereby obtain arenaceous shell (S);
B, the lower arenaceous shell of system: on the identical core shooter of another structure, make, thereby obtain lower arenaceous shell (X); Every described core shooter comprises frame (1) and two core boxes, its mid frame (1) top is installed with the storage sand storehouse (2) of an open top, the sand export in this storage sand storehouse is communicated with the sand inlet of penetrating Sha Cang (4) by a flexible pipe (3), this sand export of penetrating Sha Cang (4) is installed with two and penetrates Sha Zui (5), and penetrates Sha Cang (4) and can under the control of penetrating sand storehouse moving control mechanism, move; The sand end that enters of the described Sha Cang of penetrating (4) is installed with a high-pressure air pipe (6) and first cylinder (7), wherein high-pressure air pipe (6) communicates with the inner chamber of penetrating Sha Cang (4), the piston rod of described the first cylinder (7) reaches to be penetrated in Sha Cang (4) inner chamber, and this inserting end is installed with an energy will penetrate the sprue that Sha Cang (4) sand inlet is blocked; Described two core boxes can relatively move under the drive of core box moving control mechanism, on these two core boxes, are equipped with heating tube (8);
Described storage sand storehouse (2) is vertical setting, and upward, sand export down for its sand inlet; Described two core boxes are positioned at below, storage sand storehouse (2), and these two core boxes are left and right and are arranged side by side, and are specially left core box (9) and right core box (10), and described in the top correspondence of right core box (10), penetrate Sha Zui (5) and have sand inlet;
C, making cast gate: in valve gated mold, put into molding sand, after heating, make cast gate;
D, matched moulds: first the lower arenaceous shell (X) making in step b is put into the lower iron-clad (XT) of making in advance, the shape of the shape of this lower iron-clad inner chamber and lower arenaceous shell (X) outer wall matches, then the upper arenaceous shell (S) making in the above step a of top cover of lower arenaceous shell (X), the end face of the bottom surface of arenaceous shell lower disk portion and lower arenaceous shell (X) laminating on this, the axial line of these two arenaceous shells, on same straight line, and forms the die cavity of casting flywheel after upper and lower arenaceous shell matched moulds; Secondly the cast gate section on arenaceous shell (S) top puts a upper iron shell of making in advance (ST) on described, the end face of the bottom surface of this upper iron shell inner chamber and upper arenaceous shell (S) lower disk portion is adjacent to, finally with U-shaped clamp, block the bottom surface of upper iron shell (ST) end face and lower iron-clad (XT), thereby upper iron shell (ST) and lower iron-clad (XT) are compressed;
E, placement cast gate: the cast gate making in step c is put into the cast gate section of described upper arenaceous shell (S), and on cast gate upper iron shell (ST) end face around, covered the tide sand of pressuring action;
F, cast: the molten iron after heating is poured into a mould from cast gate, and be 30s-1min the duration of pouring, and be 15min-30min hardening time;
G, the demoulding: take out Wheel casting blank;
H, cleaning cast gate: the dead head on Wheel casting blank is cleaned out.
In above-described processing step, during cast, molten iron enters in the die cavity of casting flywheel from cast gate, and from bottom, is upwards full of whole die cavity, and the gas that the gas that precoated sand produces and molten iron produce rises with die cavity, and discharge from cast gate, thereby solve exhausting problem.
The heat transmission of molten iron is very fast, and is passed to very soon upper and lower iron-clad place, and due to the inside of heat fast transfer molten iron discharging, the cooling quickening of product, has so fundamentally solved the casting flaws such as loose, shrinkage cavity of product.In addition, because whole upper and lower iron-clad is compressed by U-shaped clamp, the powerful expansive force producing during molten steel solidification is lockable, and product is organized tightr, and molten iron is used to form the foundry goods of flywheel substantially, so the effective rate of utilization of molten iron is very high.Finally, we can make the upper iron shell of a lot of covers, lower iron-clad and U-shaped clamp etc. in advance, and make respectively upper arenaceous shell, lower arenaceous shell and cast gate separately, finally pour into a mould, and so just can significantly improve casting efficiency.
It needs to be noted, in step a and b, core shooter used is on the basis of outsourcing, carried out very large change, be specially: core shooter is adjusted into the horizontal type structure in the present invention by the vertical structure of outsourcing, that is: described two core boxes are positioned at the below in storage sand storehouse (2), these two core boxes are left and right and are arranged side by side, be specially left core box (9) and right core box (10), and described in the top correspondence of right core box (10), penetrate Sha Zui (5) and have sand inlet, so just from top, enter sand and enter sand, thisly enter sand mode and the original sand that enters from the side has basic difference, even if adopt this structure precoated sand because humidity hardens, but precoated sand is loosening under the blowing of gases at high pressure, and from the described Sha Zui of penetrating (5), drop out under Action of Gravity Field, so just can overcome existing core shooter and easily block the defect of penetrating Sha Zui (5).
In sum, the present invention can effectively prevent the burning into sand existing in conventional cast technique, slag inclusion, pore, the casting flaw such as loose, and the present invention is efficient, cost is low, molten iron effective rate of utilization is high, to workman's labour skill, require low, and in technical process, core shooter is improved on the basis of outsourcing, after improvement, can prevent well precoated sand and block the defect of penetrating sand mouth because of moist hardening, finally make the casting technique of this flywheel creative, possess good technology and economic worth, and be suitable for promoting the use to other disc-like parts of casting or regular shape parts.
