Above-mentioned casting model powder case comprises top box and the nowel of mounted on top, described detent mechanism comprises some positioning units, each described positioning unit comprises locating clip and taper pin, the periphery at the top of described nowel is provided with flange and reinforcement, described reinforcement is vertically installed on described flange, described locating clip is fixed on described reinforcement, described locating clip is wholely set the location division stretching to described top box, described location division be just inclined-plane to the surface of described top box, thus wedge gap is formed between described location division and described top box.As preferably, described flange is installed with positioning seat, described locating clip is fixed on described positioning seat and described reinforcement simultaneously.
The casting sandbox comprising top box and nowel is applied to usually produces Conventional compact product, and it is relative fixing that the detent mechanism that nowel is arranged can realize between top box with nowel more firmly, realizes the better locating effect of casting sandbox.Wedge gap is provided with between this detent mechanism and nowel, structure is simple, easy to use, this wedge gap makes top box have certain activity space when moulding, facilitate box moulding, after taper pin being knocked in this wedge gap, what can realize between top box and nowel is relatively fixing, location and fastening top box better, thus effectively solve the distortion of molding box problem caused because of graphite expansion, reduce the casting flaw because sandbox collision produces, improve qualified casting.
Above-mentioned casting model powder case comprises the top box of mounted on top, raising middle flask and nowel, described detent mechanism comprises the first detent mechanism and the second detent mechanism, the first described detent mechanism is arranged between described top box and described raising middle flask, and the second described detent mechanism is arranged between described nowel and described raising middle flask; The first described detent mechanism comprises some positioning units, each described positioning unit comprises locating clip and taper pin, the periphery of the bottom of described top box is provided with flange and reinforcement, described reinforcement is vertically installed on described flange, described locating clip is fixed on described reinforcement, described locating clip is wholely set the location division stretching to described raising middle flask, described location division be just inclined-plane to the surface of described raising middle flask, thus form wedge gap between described location division and described raising middle flask; The second described detent mechanism is identical with the structure of the first described detent mechanism, locating clip in the second described detent mechanism is fixed on the reinforcement of described nowel top perimeter, and the reinforcement of described nowel top perimeter is installed on the flange of described nowel top perimeter.
For the casting sandbox comprising top box, raising middle flask and nowel, be generally applied to production large product, because raising middle flask is the weak link of sandbox, and when casting, the major part of foundry goods is all positioned at raising middle flask, and when therefore foundry goods expands, raising middle flask is the most easily out of shape.And the detent mechanism of the utility model casting sandbox, top box and nowel being respectively arranged with the first detent mechanism for locating raising middle flask and the second detent mechanism, because top box and nowel are subject to foundry goods expansion effects little, thus the effect of constraint raising middle flask can being played; In addition, wedge gap is equipped with at the first detent mechanism with between the second detent mechanism and raising middle flask, this wedge gap makes sandbox have certain activity space when moulding, facilitate box moulding, after taper pin being knocked in this wedge gap, can realize, to the location of raising middle flask and fastening, raising middle flask being strengthened, effectively can solve the distortion of molding box problem caused because of graphite expansion, reduce the casting flaw because sandbox collision produces.As preferably, described flange is installed with positioning seat, described locating clip is fixed on described positioning seat and described reinforcement simultaneously, to realize better location and enhancing effect.
As preferably, described positioning seat is frame-type structure.The positioning seat of frame-type structure can reduce detent mechanism materials, reduces costs.
As preferably, the flange on described top box and the flange between reinforcement and on described nowel and be all arranged at intervals with some stiffeners between reinforcement.Stiffener can further improve the intensity of top box and nowel periphery, guarantees the binding effect of detent mechanism to raising middle flask.
Compared with prior art, the utility model has the advantage of: the detent mechanism of the utility model disclosed casting sandbox, detent mechanism is provided with between its two neighbouring layer box bodies, realize between adjacent boxes by detent mechanism relatively fixing, thus avoid the relative movement in handling process between adjacent boxes and dislocation, simultaneously effectively can solve the distortion of molding box problem caused because of graphite expansion, reduce casting flaw because sandbox collision produces and bad.
