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 put
It sets at the lumen centers of sprue cup, it is ensured that the rotary table of sprue cup loose piece bottom is contacted with model；
Seam 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 in gap, 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, will pour
Cup loose piece takes out from upper swage ontology；
Step 4: upper swage ontology and lower swage ontology being subjected to mould assembly, pour into iron out of sprue cup on upper swage ontology
Water injects molten iron 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, and the utility model has the advantage that
1, the utility model places sprue cup when eliminating casting mold and shovel pours by the way that sprue cup is arranged on upper swage ontology
Cup step simplifies production process, saves production cost, improves product qualification rate.
2, the utility model is when the intrinsic upper impression of upward swage carries out covering sand, the second sand layer of sprue cup inner wall
It is connected with the first sand layer of upper impression and sprue gate inner wall, so that being not present 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 utility model in sprue cup by being arranged sprue cup movable block, convenient for carrying out covering sand in the inner wall of sprue cup
The second sand layer is formed, 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, for pouring
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 in the minimum at sprue gate
Diameter, it is ensured that can be taken out after molten steel solidification.
