Abstract
The utility model discloses a composite coating centrifugal mold of a wear-resistant ball, comprising a base, a rotating platform, an upper mold and a lower mold, wherein the upper mold and the lower mold are split horizontally; the base is rotatably provided with a rotating platform which is provided with the lower mold; a corresponding plane of the upper mold and a lower mold splitting horizontally is provided with a plurality of hemispherical cavities which are uniformly distributed around the center; the center of the lower mold is provided with a sinking groove; the sinking groove and the hemispherical cavities are communicated by runners; the center of the upper mold is provided with a riser opposite to the sinking groove; a split surface of the upper mold and the lower mold is provided with oppositely-opened air flow channels respectively along the edges of the hemispherical cavities; the front sections of the air flow channels are communicated with the hemispherical cavities and the sinking groove; the tail ends of the air flow channels extend to the side walls of the upper mold and the lower mold; and the inner walls of the sinking groove, the hemispherical cavities, the runners and the air flow channels are respectively coated with a composite coating. A product cast by the composite coating centrifugal mold has the advantages of compact organization of casting pieces, good surface quality, no pollution for the environment and low cost, so that the production quality of the wear-resistant ball generates a qualitative leap and large economic and social benefits are brought.
Description
Technical field:
The utility model relates to mould applications, relates in particular to a kind of wear-resisting ball composite coating centrifugal mold.
Background technology:
Tradition wear resisting cast ball production main method has three kinds: one, tide mould sand casting (being applicable to bead).Two, water-glass sand iron mould casting.Three, device for sand coated iron mould (resin sand) casting.Above method exists the molten iron utilization rate low, and die life is short, contaminated environment, and cost is high, all need utilize shortcomings such as molding sand.
Centrifugal casting: motlten metal pours into the casting mold around level, inclination or vertical axis rotation, under centrifugal action, and the foundry goods axis of solidification forming and the casting method of rotating the casting mold dead in line.Centrifugal casting has foundry goods dense structure, and product yield is high, and surface quality is good, environmentally safe, and cost is low, the high advantages such as (its density improve 1%-2% approximately, and hardness improves 5%-11% approximately, and tensile strength improves 4%-20% approximately) of product quality.So since the nineties in last century, people's thinking is introduced the casting of casting ball with centre spinning method, and has carried out a series of tests in succession, but answers mold material can't satisfy technological requirement eventually, can not be applied to actual production so far.
The utility model content:
The purpose of the utility model provides a kind of wear-resisting ball composite coating centrifugal mold, has thoroughly solved a difficult problem of utilizing centrifugal casting technique can't produce wear resisting cast ball, makes wear resisting cast ball production produce a kind of qualitative leap, has practiced thrift cost and human resources.
The technical scheme of the utility model is following:
Wear-resisting ball composite coating centrifugal mold; The upper die and lower die that comprise base, turntable, horizontal parting are rotatablely equipped with turntable on the base, counterdie is installed on the turntable; Corresponding flat at the upper and lower mould of horizontal parting is provided with the hemi-spherical cavities that several are uniformly distributed with around the center; It is characterized in that: described counterdie center is provided with deep gouge, is communicated with through running channel between deep gouge and the described hemi-spherical cavities, and described patrix center has the rising head over against described deep gouge; Hemi-spherical cavities edge, described upper and lower mould die joint upper edge is respectively equipped with the gas channel of splitting; The gas channel leading portion communicates with hemi-spherical cavities, deep gouge, and the gas channel end extends to upper and lower mould sidewall, scribbles composite coating on described deep gouge, hemi-spherical cavities, running channel, the gas channel inwall.
Described wear-resisting ball composite coating centrifugal mold, it is characterized in that: described hemi-spherical cavities inwall is provided with through hole.
Described wear-resisting ball composite coating centrifugal mold, it is characterized in that: described counterdie die joint is provided with equally distributed several grooves, and described patrix die joint is provided with the convexity that matches with described several grooves.
Described wear-resisting ball composite coating centrifugal mold is characterized in that: described composite coating adopts thermal spraying or deposition process, composite coating thickness range 100um-3mm.
Compare the superior part of the utility model with traditional wear-resisting ball mfg. moulding die:
1. centrifugal casting has foundry goods dense structure, and product yield is high, and surface quality is good; Environmentally safe, cost is low, and product quality is high, and (its density improves 1%-2% approximately; Hardness improves 5%-11% approximately; Tensile strength improves 4%-20% approximately) etc. advantage, make the production of wear-resisting ball produce a kind of qualitative leap, with bringing huge economic and social benefit.
2. the composite coating on the mould die joint has heat conduction, high temperature resistant impact, wear-resisting, anti-oxidant, wash away with strong, the anti-molten iron of basal body binding force, advantages such as long service life.
3. composite coating not only can use on centrifugal mold, and is applicable to the mould of a lot of other types, equally production is brought the saving on the cost.
