Connect problem not firm easy to fall off and that assembling is inconvenient.
Utility model content
The application aims to solve at least one of the technical problems existing in the prior art.For this purpose, the purpose of this utility model
One of be to provide a kind of lost foam casting running gate system easy to assembly.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of lost foam casting running gate system, including sprue cup and the sprue being connected to sprue cup, the sprue cup and
Sprue realizes by quick coupling and connects that the quick coupling includes the refractory ceramic set being arranged on the sprue cup and sets
It sets on the sprue and covers the refractory ceramic plug being adapted to the refractory ceramic.
Further, filter screen is equipped between the refractory ceramic plug and refractory ceramic set.
Further, the filter screen is the hemispherical filter screen protruded towards sprue cup direction, the hemispherical filtering
The periphery of net has been epitaxially formed annular pressing ring, and the annular pressing ring crimping is fixed on the refractory ceramic plug and refractory ceramic set
Between.
Further, the inner cavity of the sprue cup is gradually reduced from the socket end of casting ladle iron liquid to running gate system connecting pin.
Further, the lumenal cross-section of the sprue cup is inShape.
Further, the sprue cup is applied by foam sprue cup ontology and coated in the external sprue cup of foam sprue cup sheet
Bed of material composition, the sprue is by foam sprue ontology and the sprue dope layer group external coated in foam sprue sheet
At.
Further, the inner cavity of the sprue cup has extended outward to form a grade sand portion far from the side wall of sprue one end.
Compared with prior art, the utility model has the beneficial effects that:
1, it is fixedly installed with refractory ceramic set on sprue cup, is equipped on sprue and covers the fire prevention being adapted to refractory ceramic
Ceramic plug；When assembling, pair of sprue and sprue cup will directly can be realized in refractory ceramic plug insertion refractory ceramic set
It connects, it is easy to assembly quick and more firm.
2, filter screen is gripped by refractory ceramic plug and refractory ceramic set and middle part is hemispherical, effectively prevent gold
Belong to liquid to wash away sprue, improves the quality of casting.
3, the inner cavity of sprue cup is gradually reduced and in sprue cup from the socket end of casting ladle iron liquid to running gate system connecting pin
Chamber cross section is inShape prevents occurring whirlpool in casting process, solves in existing sprue cup casting process and whirlpool easily occurs
Whirlpool causes potting syrup whirlpool to go out outside sprue cup and filter residue is involved in the problems in iron liquid, improves the quality of cast.
4, the inner cavity of sprue cup has extended outward to form a grade sand portion far from the side wall of sprue one end；When casting, shelves sand portion
It stretches out outside sandbox, quartz sand when so as to effectively prevent casting in sandbox is brought into sprue cup, and casting quality is influenced.
Detailed description of the invention
Fig. 1 is the top view of the utility model；
Fig. 2 is sectional view along A-A in Fig. 1；
Fig. 3 is B-B direction cross-sectional view in Fig. 1.
Specific embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
Referring to figures 1-3, in one embodiment, a kind of lost foam casting running gate system, including sprue cup 1 and and sprue cup
The sprue 2 of 1 connection, sprue cup 1 and sprue 2 are realized by quick coupling to be connected, and quick coupling includes being arranged in sprue cup 1
The refractory ceramic plugs that refractory ceramic on outlet end covers 3 and is arranged on 2 liquid feeding end of sprue and is adapted to refractory ceramic set 3
4, when sprue cup 1 and sprue 2 connect, directly refractory ceramic plug 4, which is inserted into refractory ceramic set 3, can be realized sprue 2
Easy to assembly quick and more firm with the docking of sprue cup 1, refractory ceramic plug 4 and refractory ceramic set 3 need to use
High temperature resistant and the not ceramic material of iron liquid reaction, such as aluminium oxide.
Referring to fig. 2, in another embodiment, with above-described embodiment the difference is that in refractory ceramic plug 4 and fire prevention pottery
It is equipped with filter screen 5 between insulator 3, when iron liquid passes through filter screen 5, the filter residue in iron liquid can be filtered, reach purification
The purpose of iron liquid.Preferably, filter screen 5 is the hemispherical filter screen protruded towards sprue cup direction, the week of hemispherical filter screen
While being epitaxially formed annular pressing ring 6.Hemispherical filter screen can be effectively prevented molten metal and wash away to sprue, improve casting
Quality.Refractory ceramic plug 4 and refractory ceramic set 3 connection when, by by annular pressing ring 6 crimping be fixed on refractory ceramic plug and
Between refractory ceramic set, realize that the installation positioning of filter screen 5, the installation of filter screen 5 are also very convenient.
Referring to Fig. 1 and Fig. 2, in another embodiment, sprue cup 1 by foam sprue cup ontology 1-1 (inner hollow) and applies
The sprue cup dope layer 1-2 composition outside foam sprue cup ontology 1-1 is overlayed on, sprue 2 is by foam sprue ontology 2-1 and coating
