Abstract
A liquid lifting pipe with multiple pouring gates comprises a pipe body and a cover plate arranged at the upper end of the pipe body, wherein the cover plate is provided with multiple pouring gates. The invention relates to a special riser tube of a low-pressure casting machine for producing castings with dispersed thermal junctions or single-mold multi-cavity castings, which is matched with the low-pressure casting machine for use and can be used for producing castings of cylinder covers of automobile engines, intake manifolds, motorcycles and the like.
Description
Technical field
The present invention relates to a kind of low-pressure casting lift tube, especially a kind of stalk with multi-point sprue.
Background technology
Low pressure casting be make liquid metals under the lower pressure effect, fill die cavity, to form a kind of method of foundry goods.Its technical process is in airtight container, feeds dry compressed air, and under the effect of gas pressure, liquid metals rises along stalk, enters die cavity stably by cast gate, and keeps the gas pressure on the liquid level in the crucible; After solidifying fully to foundry goods, remove the gas pressure on the liquid level, make not solidified liquid metals backflow crucible in the stalk, take out foundry goods again.
Summary of the invention
The object of the present invention is to provide a kind of stalk that can realize the multi-point sprue cast.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of stalk with multi-point sprue comprises body and the cover plate that is arranged on the body upper end, and cover plate is provided with a plurality of cast gates.
Because the employing of technique scheme, the present invention has the following advantages:
The present invention is a kind of special-purpose stalk that is used to produce the low-pressure casting machine with the foundry goods that disperses thermal center or a multi-cavity mold foundry goods, is used with the low-pressure casting machine, can be used for the production of foundry goods such as automobile engine cylinder head, inlet manifold and motorcycle.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is a vertical view of the present invention;
Wherein: 1, body; 2, cover plate; 21, cast gate.
The specific embodiment
The stalk with multi-point sprue as shown in Figure 1 comprises body 1 and the cover plate 2 that is arranged on body 1 upper end, and cover plate 2 is provided with a plurality of cast gates 21, as shown in Figure 2.The quantity of the cast gate 21 that is provided with on the cover plate 2 is more than or equal to 3.
The present invention is used to produce the special-purpose stalk of the low-pressure casting machine with the foundry goods that disperses thermal center or a multi-cavity mold foundry goods, is used with the low-pressure casting machine, can be used for the production of foundry goods such as automobile engine cylinder head, inlet manifold and motorcycle.
