An adhesive wheel pouring system comprises a plurality of adhesive wheel pouring units, each adhesive wheel pouring unit comprises a transitional transverse pouring path, a lower straight pouring path, and a plurality of inner pouring paths, wherein the lower straight pouring path, the transitional transverse pouring path, and the plurality of inner pouring paths are communicated sequentially, and the transitional transverse pouring paths of all the adhesive wheel pouring units are communicated with one another. Each adhesive wheel pouring unit also comprises a lower transverse pouring path at the top of an adhesive wheel cavity, an upper straight pouring path vertically arranged above the lower transverse pouring path, and upper transverse pouring paths at two ends of the lower transverse pouring path, wherein the upper straight pouring paths, the lower transverse pouring paths, and the upper transverse pouring paths are communicated sequentially, the upper transverse pouring paths are communicated with corresponding lower straight pouring paths respectively, and in the lower transverse pouring path, inoculators used for preventing pouring liquid from decay and oxidation are arranged therein. The adhesive wheel pouring system can reduce the oxidation of the pouring liquid, guarantee the pouring liquid quality, and reduce shrinkage cavity and shrinkage porosity rates of castings.

Description

The mill running gate system

Technical field

The utility model relates to the manufacturing field of mining machinery product, is specifically related to a kind of mill running gate system that is used to manufacture mine levigator mill.

Background technology

In the process of manufacturing mine levigator mill, the quality of mill running gate system will directly influence the casting quality of mill.

Existing mill running gate system generally comprises vertical setting and the sprue of arranging around the mill die cavity, the transition cross gate that is provided with along mill die cavity base, radial direction is provided with along the mill bottom ingate.Said sprue, transition cross gate and ingate are communicated with successively.During cast, the potting syrup in the pouring basin is injected in the mill die cavity behind the sprue, transition cross gate and the ingate that are communicated with successively, the final required mill foundry goods of moulding by casting.

At present, since the size of mine levigator mill very big (Fig. 1 be a kind of mine levigator mill, the height H=2945mm of this mill, goes up diameter=3780mm, time diameter=5940mm); In the cast series products, belong to heavy castings, not only need a large amount of potting syrups, and need the long duration of pouring; In casting process; Directly enter into the mill running gate system of above structure like the potting syrup in the pouring basin, the oxidation of potting syrup is then comparatively obvious, makes in the potting syrup oxidizing slag more; Thereby influence the potting syrup quality, it is bigger to make foundry goods the probability of shrinkage cavity, shrinkage porosite occur.

Summary of the invention

The technical problem that the utility model will solve is, provides a kind of and can reduce the phenomenon that oxidation appears in potting syrup, ensures the potting syrup quality, reduces the mill running gate system that shrinkage cavity, shrinkage porosite probability appear in foundry goods.

For solving the problems of the technologies described above; The utility model adopts a kind of like this mill running gate system; It comprises a plurality of mill cast unit that is provided with around the mill die cavity; Each mill cast unit comprises the transition cross gate that is arranged on the mill cavity bottom, vertically is arranged on the following sprue at two ends, transition cross gate top and a plurality of ingates that are arranged on transition cross gate below and extend along mill cavity bottom radial direction; Said sprue, transition cross gate, a plurality of ingate down are communicated with successively; The transition cross gate of each mill cast unit is communicated with mutually, and each mill cast unit also comprises the following cross gate that is arranged on the millstone type top of chamber, vertically is arranged on down the last sprue of cross gate top and the last cross gate that is arranged on down the cross gate two ends, and said upward sprue, following cross gate, upward cross gate is communicated with successively; The said cross gate of going up is communicated with each self-corresponding sprue down, is placed with the inovulant that prevents potting syrup decline, oxidation in the said cross gate down.

Be provided with filter block between said cross gate down and the last cross gate.

Said mill cast unit is 4, and these 4 mill cast unit evenly distribute around the mill die cavity.

After adopting above structure; The utility model compared with prior art; Have the following advantages: because each mill cast unit also comprises the following cross gate that is arranged on the millstone type top of chamber, vertically is arranged on down the last sprue of cross gate top and the last cross gate that is arranged on down the cross gate two ends, saidly go up sprue, following cross gate, upward cross gate is communicated with successively, sprue was communicated with under said upward cross gate and each were self-corresponding; And be placed with the inovulant that prevents potting syrup decline, oxidation in the said cross gate down; The placement of this inovulant can be played modified effect to potting syrup, and potting syrup is carried out inoculation process, has effectively prevented decline and the oxidation of potting syrup and forms oxidizing slag; Ensure the quality of potting syrup, reduced the probability that shrinkage cavity, shrinkage porosite appear in foundry goods.

As improvement; Be provided with filter block between said cross gate down and the last cross gate; When potting syrup is gone up cross gate from descending cross gate to flow into; Be located at down crossing filter block and can play the pushing off the slag effect between cross gate and the last cross gate, further improved the quality of potting syrup, further reduced the probability that shrinkage cavity, shrinkage porosite appear in foundry goods potting syrup.

As further improvement, said mill cast unit is 4, these 4 mills cast unit evenly distribute around the mill die cavity, and potting syrup is flowed in the mill die cavity fast, uniformly, has further reduced the probability that shrinkage cavity, shrinkage porosite appear in foundry goods.

Description of drawings:

Fig. 1 is the structural representation of the mill running gate system of the utility model.

Fig. 2 is the sectional structure sketch map of the mill running gate system of the utility model.

Shown in the figure: 1, following sprue, 2, the transition cross gate, 3, a plurality of ingate, 4, the mill die cavity, 5, go up sprue, 6, cross gate down, 7, go up cross gate, 8, cross filter block.

The specific embodiment:

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.

As depicted in figs. 1 and 2; The mill running gate system of the utility model; It comprises a plurality of mills cast unit that is provided with around mill die cavity 4, and each mill cast unit comprises the transition cross gate 2 that is arranged on mill die cavity 4 bottoms, a plurality of ingates 3 that vertically are arranged on the following sprue 1 at two ends, transition cross gate 2 top and are arranged on transition cross gate 2 belows and extend along mill die cavity 4 bottom radial direction.Said sprue 1, transition cross gate 2, a plurality of ingate 3 down are communicated with successively.The transition cross gate 2 of each mill cast unit is communicated with mutually, and is communicated with the bottom that is centered around mill die cavity 4 circlewise.
