Abstract
The utility model relates to a casting molding core of a part of a railway system, and particularly provides a railway wagon swing bolster mold core provided with a novel support structure. The railway wagon swing bolster mold core provided with the novel support structure comprises end portion mold core bodies located inside an outer mold, and a central mold core body arranged between the two end portion mold core bodies in a butt joint mode, and the outer mold, the end portion mold core bodies and the central mold core body jointly form a sand mold which is provided with a mold cavity used for defining an inner surface and an outer surface of a swing bolster. Core heads for supporting and positioning are arranged on two sides of an end face where one end portion mold core body and the central mold core body are in butt joint, each end portion mold core body extends outwards to form an end portion supporting assembly, and therefore the problem that an integrated mold core is hard to manufacture and operate can be effectively solved.
Description
Technical field
The utility model relates to the casting core of a kind of railway system parts, specifically a kind of truck bolster for railway wagon core with Novel support structure.
Background technology
Bolster is the part of roller bearing adapter stabilizer bar, bogie truck is one of parts of paramount importance in the guideway vehicle structure, its Main Function is support car body and bear and transmit from car body between wheel or from wheel track to various load and application force between car body, make the even distribution of axle weight average, guarantee the safe operation of vehicle, can move and waltz through curve along the straight line circuit neatly.Bolster is a kind of load carrier that turns to, play a part transmission of pressure and tractive force, because performance requriements is more special, therefore bolster adopts the mode of casting to produce more, its end core of traditional bolster foundry technique is combined by up and down two labels, and do not comprise the support of both sides, usually by stud support, the location.Due to the existence of stud, cause defective hidden danger to reduce the reliability of product in the foundry goods body thereby often give.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of truck bolster for railway wagon core with Novel support structure, can actv. solves split core intensity low, and core assembly is unreliable, the shortcoming that needs stud to support.
the utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of truck bolster for railway wagon core with Novel support structure, comprise the end core in external form and be docked at two central core between the core of end, described external form, end core and central core are together to form to be had in the bolster of defining, the bolster integral sand mold of the die cavity of outside face, described end core is whole shape structure, the end core docks with central core end face both sides are provided with the lateral support member that supporting and location is used, the described end core formation end support member that stretches out.
Described external form inner chamber side is provided with places the die cavity core print seat that core both sides, end core print is used.
Described external form inner chamber two ends are provided with the end core print seat that the end support member of placing the end core is used.
Be equipped with the core face that closes on described core, fuse interface separately.
Beneficial effect: a kind of truck bolster for railway wagon core with Novel support structure of the utility model, its end core is provided with support, align member in the both sides of docking end face with central core, the end core formation end support member that stretches out, can make the end core directly be placed on the core print seat inside of external form, this end core has independent support, and have side direction, vertically, the three-dimensional limit function in up and down.Make the end core break away from dependence to stud, avoided moving because of it casting deformation that causes.
Description of drawings
Fig. 1 is birds-eye view of the present utility model;
Fig. 2 is lateral plan of the present utility model;
Fig. 3 is the birds-eye view of the utility model end core when being placed in external form.
Mark in figure: a, end core, b, central core, c, external form, a-1, lateral support member, a-2, end support member, 12, the die cavity core print seat, 13, the end core print seat.
The specific embodiment
below in conjunction with the description of drawings specific embodiment of the present utility model: a kind of truck bolster for railway wagon core with Novel support structure, comprise the end core a in external form c and be docked at two central core b between the core of end, described external form c, end core a and central core b are together to form to have in the bolster of defining, the bolster integral sand mold of the die cavity of outside face, described end core is whole shape structure, the end core docks with central core end face both sides are provided with the lateral support member a-1 that supporting and location is used, described end core stretches out and forms end support member a-2.
Described external form c inner chamber side is provided with the die cavity core print seat 12 that the core print of placing the end core is used.
Described external form c inner chamber two ends are provided with the end core print seat 13 that the end support member a-2 that places the end core uses.
Be equipped with the core face that closes on described core, fuse interface separately.
Described external form refers to hold the outside sand mold of the integrated of fuse or core.
end core a and central core b are placed in external form c jointly, end core a docks with central core b end face both sides are provided with the lateral support member a-1 that supporting and location is used, external form inner chamber side is provided with places the die cavity core print seat 12 that core both sides, end core print is used, the end core stretches out and forms end support member a-2, when core and fuse combination, the end support member a-2 of end core puts in the end core print seat 13 of external form, end core a puts into the end of external form under the location of lateral support member a-1 and end support member a-2, central core b is docked between the core a of end, be equipped with the core face that closes on interface separately, docking between facilitating separately.
