Abstract
The invention discloses a die, which includes a die body composed of a lower die equipped with a hemispherical cavity internally and an upper die equipped with a hemispherical curve cavity, a heat preservation cavity disposed on the upper die and communicated with the outside, and a heat preservation die body embedded in the heat preservation cavity. The heat preservation cavity is communicated with the hemispherical curve cavity, the inlet of the heat preservation cavity is provided with an annular step slot, and the outer edge of the heat preservation die body is provided with an annular flange matching the annular step slot. One upper end side of the upper die is provided with a pouring gate, which is communicated with the hemispherical curve cavity of the upper die through a channel disposed in the heat preservation die body. Grinding balls poured by the die provided in the invention overcome the shrinkage cavity, porosity and other defects inside the balls, and have substantially improved wear resistance. The installation of a high-melting-point filtration net with fine meshes at a sprue gate of the die can significantly reduce dregs in the poured and molded grinding balls, so that the yield and quality of castings can be enhanced.

Background technology
Mould namely on industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is the instrument of formed article, and this instrument is made of various parts, and different moulds is made of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.Casting mould refers to that common hand moulding is commonly used wooden mold in order to obtain the model of qualified parts, plastic pattern, and the multiplex metal pattern of machine moulding, as: aluminium pattern, swage type.Hot investment casting wax pattern, evaporative pattern polystyrene model.Casting mould refers in order to obtain the planform of part, make in advance the planform of part with the material of other easy moulding, and then in sand mold, put into mould, so just formed a cavity the same with the design of part size in the sand mold, the mobile liquid of cast in this cavity just can form and the duplicate part of mold shape structure after this liquid cools is solidified again.
The abrading-ball of existing casting mould, it is inner easily to produce shrinkage cavity and the defective such as loose, and it is early stage broken that abrading-ball is easily produced in the course of the work.Shape and the Position Design of the metal type dies insulation die body that adopts at present simultaneously are unreasonable, fail to reach the indices of expection.And existing casting generally directly pours into motlten metal in the mold cavity, and it is high to make foundry goods after the moulding contain the dregs composition, and yield rate is low and casting quality can't be guaranteed.
Summary of the invention
Technical problem to be solved by this invention provides a kind of with filter effect, reduces the mould of abrading-ball defective and raising abrading-ball wearability.
The present invention is achieved through the following technical solutions: a kind of mould, the bed die of establishing hemispherical cavity in comprising with in establish the die body that the mold of hemispherical curved surface cavity forms, and be arranged on mold and the extraneous incubation cavity that communicates, and be flush-mounted in insulation die body in the incubation cavity, described incubation cavity communicates with hemispherical curved surface cavity, and offer the ring ladder groove in the incubation cavity porch, describedly be provided with the annular lip that matches with the ring ladder groove in insulation die body outer rim, described mold upper end one side offers running channel, and running channel communicates with the hemispherical curved surface cavity of mold by the passage that is provided with in the insulation die body.
As preferably, described running channel comprises running channel, down sprue and runner from top to bottom successively, the opening of described upper running channel is large, the opening of down sprue is little, and upper running channel and down sprue all are the inverted round stage shape, described porch at down sprue is concordant to arrange one for the screen pack that filters dregs, and the fusing point of described screen pack is higher than the fusing point of die body.
As preferably, described screen pack is set to inner concavity, and the surface of the limit, outer of screen pack and upper running channel inner chamber is close to.
As preferably, described runner is set to freely glide skewed, and the axis of the axis of runner and insulation die body passage is coaxial.
As preferably, be provided with a little hemi-spherical cavities and an inverted round stage hole in the described insulation die body, the bottom surface in inverted round stage hole and little hemi-spherical cavities intersect, and the end face in inverted round stage hole and passage intersect, and in the upper end of insulation die body handle are set.
As preferably, scrobicular ring is offered in the lower end of described mold, is provided with the bulge loop that cooperates scrobicular ring to install in the upper end of bed die.
As preferably, described mold and bed die adopt spheroidal graphite cast-iron to make, and described insulation die body adopts red sand or silicate fiber to make.
The beneficial effect of mould of the present invention is: the abrading-ball of this die casting, overcome and have shrinkage cavity and the defective such as loose in the ball, greatly improve the wearability of abrading-ball, settle the high-melting-point screen pack of fine and closely woven mesh at die casting mouth place, dregs in the cast molding abrading-ball are reduced in a large number, improve yield rate and the casting quality of foundry goods.
