Description
Technical field
The present invention relates to casting technique equipment field, in particular to a kind of the swage and its casting method of included sprue cup.
Background technique
Sand-Faced Metal Mould Casting belongs to one of Special Processes of Metal Castings, and casting mold is to be covered with a thin layer precoated sand on metal mold inner cavity to be formed
Casting mold.Iron Mould Coated Sand mold tooling generally comprises: upper swage, lower swage, model, sprue cup etc..Sand-Faced Metal Mould Casting is mainly given birth to
Production process are as follows: upper and lower swage mould assembly after covering sand molding forms casting mold, then the sprue cup separately made is placed on casting mold；Molten iron from
Sprue cup pours into casting mold, molten iron not completely solidify when by sprue cup together in sprue cup molten iron shovel fall, allow casting from
It is taken out in type；When molten iron solidifies completely and reaches unpacking temperature, by upper swage and lower swage open form, casting is further taken out.The life
Production process needs another sprue cup processed, and the process for needing and putting sprue cup, shovel sprue cup；The sprue cup separately made is usually to use glue
Water is sticked on casting mold, and molten iron is easy to break through the sand of joining place in casting process, and the casting of production is made to have the defects of sand holes；Shovel
Sprue cup shovel must fall when molten iron does not solidify completely, opportunity bad assurance, and too early then molten iron does not solidify, and molten iron is made to flow to iron
The type back side, then molten iron solidifies completely too late, and casting can not take out out of type.
Summary of the invention
The object of the present invention is to provide the swages and its casting method of a kind of included sprue cup.The present invention passes through upper
The step of sprue cup is arranged on swage ontology, sprue cup and shovel sprue cup are put when eliminating casting mold, simplifies production process, saves life
Cost is produced, product qualification rate is improved.
Technical solution of the present invention: a kind of swage of included sprue cup, including mutually matched upper swage ontology and lower iron
Type ontology, the upper swage ontology is interior to be equipped with upper impression, and the upper swage ontology is equipped with sprue gate, and sprue gate is equipped with funnel

Two sand layers, the sprue cup is interior to be equipped with sprue cup loose piece；It is equipped with lower impressions in the lower swage ontology, is set in the lower impressions
There is the third sand layer with the cooperation of the first sand layer；Die cavity is formed between first sand layer and third sand layer.
In the swage of above-mentioned included sprue cup, what second sand layer was linked together with the first sand layer.
In the swage of included sprue cup above-mentioned, the sprue cup loose piece is funnel-form, and the diameter of bottom is less than top
Diameter；The bottom end of the sprue cup loose piece is equipped with rotary table.
In the swage of included sprue cup above-mentioned, sprue cup loose piece maximum gauge suitable for reading is less than the minimum at sprue gate
Internal diameter.
In the swage of included sprue cup above-mentioned, sprue cup loose piece maximum gauge suitable for reading is less than the minimum at sprue gate
Internal diameter.
The casting method of the swage of included sprue cup above-mentioned, comprising the following steps:
Step 1: upper swage ontology, lower swage ontology and the pattern after heating being molded, and sprue cup loose piece is placed on
At the lumen centers of sprue cup, it is ensured that the rotary table of sprue cup loose piece bottom is contacted with model；
In gap between the upward swage ontology of step 2 and model, upper swage ontology and sprue cup loose piece, lower swage ontology and pattern
Precoated sand is inserted, precoated sand is respectively formed the first sand layer, the second sand layer and third sand layer after by heat cure；
Step 3: upper swage ontology and model being opened, upper swage ontology takes sprue cup loose piece out of together, by sprue cup
Loose piece takes out from upper swage ontology；
Step 4: upper swage ontology and lower swage ontology are subjected to mould assembly, pour into molten iron out of sprue cup on upper swage ontology,
Molten iron is injected to die cavity；
Step 5: after molten iron cooled and solidified, upper swage ontology and lower swage ontology open form taking out casting.
The prior art is compared, the invention has the following advantages that
1, the present invention places sprue cup and shovel sprue cup step by the way that sprue cup is arranged on upper swage ontology when eliminating casting mold
Suddenly, simplify production process, save production cost, improve product qualification rate.
2, the present invention when the intrinsic upper impression of upward swage carries out covering sand, the second sand layer of sprue cup inner wall with it is upper
First sand layer of type chamber and sprue gate inner wall is connected, so that there is no seams between sprue cup and upper swage ontology
Gap efficiently avoids improving product qualification rate because of casting flaws such as the sand holes for putting sprue cup generation.
3, the present invention is formed by the way that sprue cup movable block is arranged in sprue cup convenient for carrying out covering sand in the inner wall of sprue cup
Second sand layer, wherein the bottom of sprue cup is equipped with rotary table, and the diameter of rotary table bottom is less than the diameter at top, is used for sprue cup
Loose piece is placed on model and is positioned, and the maximum inner diameter suitable for reading of the sprue cup loose piece is less than the minimum diameter at sprue gate, really
It can be taken out after protecting molten steel solidification.
