The non-riser casting device is characterized by comprising a sprue cup, a transverse sprue runner and a straight sprue runner, wherein the cross section of both of the transverse sprue runner and the straight sprue runner is trapezoidal; pouring units of three casting forming moulds are respectively arranged at two sides of the straight sprue runner; the straight sprue runner is provided with a flow chock A, a flow chock B and a flow chock C, the flow chock A is arranged in an intersection of the transverse sprue runner and the straight sprue runner, and the flow chock B and the flow chock C are arranged on the straight sprue rubber; and a necking A, a necking B, a necking C, a necking D, a necking E and a necking F are respectively arranged at a combined part of the straight sprue runner and the casting forming mould and are communicated with the casting forming mould. The non-riser casting device has the advantages that a non-riser casting system is simple in structure, is easy to embody and convenient to operate; and when the castings of air condition compressor are produced, the rate of finished products of the castings can be increased, the cost can be reduced, the appearance quality of the castings can be improved, and the postprocessing is easy.
Description
Technical field
The utility model relates to the casting of nodular iron casting, particularly a kind of head-free casting device that is used for the vehicle wheel shaft foundry goods.
Background technology
During the vehicle wheel shaft castings production, adopt the flow production line operation usually.What our factory adopted is Denmark DISA230 mould on end line.In this mo(u)lding line, using the area of mould template is (650 * 535) mm
2, but when actual production, the area of the real mould template that utilizes is limited.When adopting traditional foundry goods to add the casting technique of rising head, need calculate the modulus of rising head usually according to the modulus of foundry goods thermal center, and confirm the size of rising head with this, form whole running gate system through ingate connection rising head or foundry goods again.But because rising head and running channel occupy template face area greatly, template plate face is not fully utilized, not only the castings production rate is low, cost is high, and the post processing difficulty.
The utility model content
The purpose of the utility model is to above-mentioned existing problems, provide a kind of simple in structure, easy to implement, post processing is easy, easy to operate and can improve the no riser gating device that is used for the vehicle wheel shaft foundry goods of castings production rate.
The technical scheme of the utility model:
A kind of no riser gating device of vehicle wheel shaft foundry goods; It is characterized in that: comprise cup, cross gate and sprue; The cross section of cross gate and sprue is ladder type; The both sides of sprue are respectively equipped with the cast unit of three foundry goods patterns, and sprue is provided with choked flow A, choked flow B and choked flow C, and wherein choked flow A is arranged at cross gate and sprue intersection; Choked flow B and choked flow C are arranged on the sprue, and necking down A, necking down B, necking down C, necking down D, necking down E and necking down F lay respectively at sprue and communicate with the joint portion of foundry goods pattern and with the foundry goods pattern.
Said cross gate is identical with sprue ladder type sectional area, and the length of the upper base in ladder type cross section is 1/2nd of the length of going to the bottom, and height is identical with the length of going to the bottom.
The shape of said necking down A, necking down B, necking down C, necking down D, necking down E and necking down F is identical with sectional area, and the sectional area of necking down is 1.5 times of sprue sectional area, and the width of necking down and foundry goods overlap joint is 1.5-2mm, and length is go to the bottom 1.5 times of length of sprue.
The distance of said choked flow B and choked flow C and necking down B and necking down C is 15-20mm.
The design principle of the utility model:
In order to make sprue that the feeding effect of rising head arranged, so directly on sprue, make necking down; In order to make the type that fills of whole running gate system ability while and quick and stable, choked flow is set on sprue, there are not latent defect and good surface appearance such as shrinkage cavity, shrinkage porosite to guarantee foundry goods.Because the loss of partial discharge is arranged in filling the process of type, so the sectional area of choked flow must be bigger than the overlap joint area of necking down and foundry goods, this running gate system is set at 1.3 times.Though each necking down is identical with foundry goods overlap joint area, the flow of each bottleneck is different, and the flow of each bottleneck can draw to the vertical height of necking down bottom surface and the Time Calculation of cast according to cup.
The utility model has the advantages that: this no riser gating apparatus structure is simple, easy to implement, easy to operate, when producing the vehicle wheel shaft foundry goods, can improve casting yield, reduces cost, improves the visual quality of casting, post processing is easy.
