Abstract
The utility model provides a tramcar wheel casting mould which is characterized in that metal chill rings between a pre-cast upper even core and a pre-cast lower even core or an upper sand mould and a lower sand mould. The tramcar wheel casting mould can cast tramcar wheels, not only has the advantages of less sand and low manufacturing cost, no need of mechanical processing to the wheel tread and high working efficiency, but also chills and hardens the wheel surface with the help of the metal chill rings, and the inside of the wheel is kept soft, so that the wheel has quite good deformation resistance capability, breakage resistance capability, anti-corrosion capability and quite high anti-fatigue strength. In addition, the tramcar wheel casting mould also has the advantages of convenience and quickness in knockout, high finished product rate of casting and low labor intensity.
Description
Technical field
The utility model relates to a kind of mould, and especially a kind of mine tram wheel casting mould belongs to the machine casting technical field.
Background technology
For many years, the ore that comes out of mining transports by mine car mostly.According to the auxilliary requirement of establishing of mine rail, tramcar wheel must have enough load-carrying abilities, tread must be hard, wear-resisting, but can not gnaw rail, especially when wheel is subjected to shock loading, except that requiring it to have higher non-deformability and the anti-disrumpent feelings ability, also require wheel must have certain fatigue resistance, to improve the service life of mine car.In addition, soak wheel, require wheel to possess certain resistance to corrosion for preventing mineral dust, big G﹠W.Existing tramcar wheel generally forms by full sand mold or all-metal die cast, and perhaps by forging base, machined forms.Should long-lived requirement under abominable mining condition but all can not satisfy.Therefore, be necessary fully prior art is improved.
Summary of the invention
The purpose of this utility model be to provide a kind of can cast out have higher resistance to deformation, anti-disrumpent feelings ability, and fatigue resistance height, the casting mould of the tramcar wheel that decay resistance is strong.
The utility model is finished by following technical proposal: a kind of mine tram wheel casting mould is characterized in that between prefabricated upper and lower mud core or upper and lower sand mold metal cold shock circle being set.
Described prefabricated last mud core is made as the disk of band center hole, and the upper surface of disk is the plane, and the lower surface is provided with the annulus of a circle projection, is used to form the disc of wheel, and this disk is made by core sand in core box in advance.
Described mud core down is made as disk, the lower surface of disk is the plane, the center of upper surface is provided with the bullet core post of projection, be used to form the axis hole of wheel, play the annulus that is provided with a circle projection between core post and the edge, be used to form the interior tread of wheel, be interval with the cylinder of projection on the annulus, be used to form the through hole on the wheel, this disk and bullet core post are made by core sand in core box in advance.
Described metal cold shock circle is to be with bell-mouthed hollow circular cylinder, is used to form the outer tread of wheel, and cylindrical upper and lower end face is respectively equipped with the locating table of a circle projection, so that can accurately locate when joining core.
Scribble a dope layer on the described metal cold shock circle inner headed face, so that the demoulding, help prolonging the service life of cold shock circle simultaneously.
Described metal cold shock circle periphery is provided with the reinforcement of symmetry, to prolong the service life of cold shock circle, is convenient to the demoulding simultaneously.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can cast tramcar wheel easily, not only sand using amount is few, production cost is low, need not wheel tread is carried out machined, high efficiency again, the more important thing is by the effect of metal cold shock circle, the wheel wheel face is carried out Quench and hardening, inner then keep softer performance, thus make wheel have preferable non-deformability, anti-disrumpent feelings ability, resistance to corrosion and higher fatigue resistance.In addition, the utility model also has and is convenient in demoulding, fast casting yield height, the advantage that labour intensity is low.
