Description

Wheel disc mold

Technical field

The utility model belongs to shape casting field, more particularly to a kind of wheel disc mold.

Background technology

The application of wheel disc is very extensive, is related to some and manufactures equipment, automobile equipment and field of ship equipment, One type wheel disc includes inside and outside wheel disc, and inside and outside wheel disc is connected by diameter item.In traditional handicraft, inside and outside wheel disc, diameter item difference Casting processing is carried out, then again by being welded to connect, but it is not integral molding, and structure existing defects, intensity is insufficient, adds Work technique is also complex.Integral molding mold is used in the prior art, is only to be provided with one at lateral location to pour Runner is cast, casting liquid eventually arrives at interior wheel disc place runner from runner where outer wheel disc, diameter item successively, is finally completed molding, this Casting liquid may not be able to completely arrive at runner where interior wheel disc during a, since flow passage route is long, flow resistance causes to cast greatly Liquid cannot reach all forming areas of forming cavity before cooling, so wheel disc after molding can still have casting flaw.

Utility model content

The purpose of this utility model is to provide a kind of wheel disc molds, it is ensured that takes turns the casting and forming quality of disk-like accessory.

To achieve the goals above, the utility model takes following technical scheme：A kind of wheel disc mold, including two, mold Corresponding upper and lower mould has forming surface on upper and lower mould and is enclosed the forming cavity of wheel disc, the upper and lower mould after molding each other On be disposed at least two runners, the outlet end of runner extends to the middle part of forming cavity, and the input end of runner extends to mold table Face and arranged adjacent.

It in above-mentioned technical proposal, is disposed with multiple runners and is connected to forming cavity, simultaneously to multiple input ends of arranged adjacent Injection casting liquid, casting liquid flow into the middle part of forming cavity from multiple outlet ends, and flow passage route reduces and ensures to cast liquid therefrom The molding of inside and outside wheel disc is completed to flows outside in portion, it is ensured that castability.

Specific implementation mode

It is made further instructions in conjunction with 1~4 pair of the utility model of attached drawing：

A kind of wheel disc mold, including the corresponding upper and lower mould 10,20 of two, mold, have on upper and lower mould 10,20 forming surface and It is enclosed the forming cavity 30 of wheel disc after molding each other, at least two runners 40 are disposed on the upper and lower mould 10,20, flows The outlet end 41 in road 40 extends to the middle part of forming cavity 30, and the input end 42 of runner 40 extends to die surface and arranged adjacent. It is disposed with multiple runners 40 to be connected to forming cavity 30, casting liquid is injected simultaneously to multiple input ends 42 of arranged adjacent, liquid of casting The middle part of forming cavity 30 is flowed into from multiple outlet ends 41, flow passage route reduces and ensures that casting liquid has been flowed from the outside portion in middle part At the molding of inside and outside wheel disc, it is ensured that castability.

The forming cavity 30 includes interior wheel disc chamber, diameter chamber, the outer wheel disc chamber 31,32,33 being sequentially communicated, the stream The outlet end 41 in road 40 is arranged in the inner bottom surface of lower die 20 and correspondence is connected to each diameter chamber 32.Between interior wheel disc and outer wheel disc Diameter item be evenly arranged, multiple outlet ends 41 respectively it is corresponding with diameter chamber 32 connection, casting liquid enter diameter chamber 32 inwardly, Interior wheel disc chamber, outer wheel disc chamber 31,33 are flowed to outside, are shortened the shape casting time while being ensured the castability of wheel disc.

The runner 40 is ceramic tube, and the input end 42 of ceramic tube extends to the upper surface of lower die 20.Ceramic tube is heat-resisting, Wear-resisting, the corrosion-resistant runner 40 for as casting, it is ensured that the upper table at 20 edge of lower die is arranged in Forming Quality, input end 42 Face, after upper and lower mould 10,20 molds, casting gate is connected with input end 42, and casting liquid is directly entered input end 42 from casting gate, makes pottery The selection of porcelain tube is conducive to constitute runner, it is ensured that casting liquid stream is dynamic and flow resistance is small while easy to disassemble.

The lower die 20 is equipped with flange 21, postpones and turns over from bottom to top in the molding sand that runner 40 is coated by 20 periphery of lower die Side 21 connects.Lower die 20 can use molding sand to manufacture completely, can also be mold made of metal material as core model, outside core model It is coated with molding sand week, and ceramic tube passes through connection casting gate and forming cavity 30 as runner 40 from molding sand, the setting of molding sand is just Arrangement in ceramic tube and dismounting.

The flange 21 offers casting gate 22, and the input end 42 of runner 40 is located in casting gate 22, the upper mold 10 offer through-hole corresponding with casting gate 22 11.After upper and lower mould 10,20 molds, injection casting liquid, is poured since in through-hole 11 It casts input end 42 of the liquid out of casting gate 22 and enters forming cavity 30.

The runner 40 includes horizontally disposed ceramic bottom tube 43, the both ends of ceramic bottom tube 43 respectively with upwardly extend Ceramic bend pipe 44 connects, and the open end of the ceramic bend pipe 44 at both ends extends respectively to the inner bottom surface of lower die 20, in casting gate 22.Pottery Porcelain bottom tube 43, ceramic bend pipe 44 setting convenient for before casting to the arrangement of runner, can very easily will be ceramic after casting and forming Bottom tube 43, ceramic bend pipe 44 are detached and are dismantled.
