Abstract
The utility model relates to a multi-tubular and multi-pouring-gate riser tube, which comprises a plurality of tube bodies and a cover plate arranged at the upper ends of the tube bodies. The multi-tubular and multi-pouring-gate riser tube is characterized in that the cover plate is connected with the upper ends of the tube bodies. The riser tube with the structure comprises a plurality of independent small riser tube bodies; the number of the served riser tube bodies is determined by the number of pouring gates of a product; the temperatures of aluminum liquid in the riser tube bodies are balanced; the riser tube bodies are easy to manufacture, low in cost, simple in structure and convenient to mount; liquid rising time is shortened, and the quality of castings is guaranteed; and the multi-tubular and multi-pouring-gate riser tube is used for a multi-cavity and large-size mold.
Description
Technical field
The utility model relates to a kind of stalk, relates in particular to a kind of many cast gates of multitube stalk, belongs to the Mechanical processing of casting field.
Background technology
Be the stalk schematic diagram of the single stalk multi-point sprue of peviform in the prior art such as Fig. 1 and Fig. 2, comprise body 3 and the cover plate 1 that is arranged on body 3 upper ends, be provided with a plurality of cast gates 2 on the cover plate, the stalk of this this structure need to rise metal aluminium liquid full to the basin of upper end, being full of aluminium liquid and could passing through the cast gate moulding in basin, filling time is long especially and marginal portion temperature of aluminum liquid decline basin is very fast, can affect to casting quality.
There is following problem in existing stalk: 1. stalk structure, making are too complicated.2. stalk is excessive, and difficulty is installed.Pressing time long, and need very large pressure.4. the basin mouth is too large, and the temperature of aluminum liquid at the two ends of length direction descends fast.Casting efficient is not high, beat is longer; Peviform stalk cost of manufacture is higher.
The utility model content
Technical problem to be solved in the utility model provides a kind of many cast gates of multitube stalk, and the stalk filling time that overcomes the single stalk multi-point sprue of traditional peviform is long, defective fast, high in cost of production that basin edge temperature of aluminum liquid descends.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of many cast gates of multitube stalk, comprise body and the cover plate that is arranged on described body upper end, and it is characterized in that, described cover plate links to each other with a plurality of bodys upper end.Its body front end can be the cast gate of stalk.
The beneficial effects of the utility model are: a plurality of independently small-sized stalks can have the several stalks of several cast gates for product; The Aluminum temperature equalization of each stalk; Stalk is made simply, cost is low; Stalk is installed simple and convenient; Shorten rising the liquid time, guarantee casting quality; Use and a multi-cavity mold, the mould that product size is larger.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described cover plate with link to each other more than or equal to the sealing of two bodys upper end.
Further, described body is hollow circular cylinder.
Further, described internal diameter of tube body is identical with described gate diameter.
Further, described body and cover plate one or split form.

In the accompanying drawing, the list of parts of each label representative is as follows:
1, cover plate, 2, cast gate, 3, body, 4, cover plate, 5, body, 6 cast gates
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 3, Figure 4, be a kind of many cast gates of multitube stalk, comprise body 5 and the cover plate 4 that is arranged on described body upper end, described cover plate 4 links to each other with a plurality of bodys 5 upper ends, and the body front end is the cast gate 6 of stalk.Described body 5 is hollow circular cylinder, described cover plate 4 with link to each other more than or equal to the sealing of two body 5 upper ends.Described body 5 internal diameters are identical with described cast gate 6 diameters.Described body 5 can one or split formation with cover plate 4.
The utility model is used in conjunction with the low-pressure casting machine for the production of the special-purpose stalk of the low-pressure casting machine of the foundry goods with dispersion thermal center or a multi-cavity mold foundry goods or long size foundry goods, can be used for the production of the foundry goods such as automobile engine cylinder head, cylinder body, long manifold.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
