Applied in many fields.
Thin wall blast pipe material C content is low, and graphitization expansion is small, and graphitization expansion can not be from the receipts of feeding focus part
Contracting, and the structure of most of blast pipe magnesium iron material solidify when many places isolated hot spots be present, due to molten iron shrinkage character and
Cooling effect, at focus and it is also easy to produce shrinkage porosite and causes gas leakage, cold shut.In order to prevent the generation of defect, it is necessary to design a kind of special
Feeding channel solve the problems, such as shrinkage porosite.
(3) utility model content：
The purpose of this utility model is to provide a kind of casting pattern structure for thin-walled exhaust tubing product, and it can
Solve the deficiencies in the prior art, be that one kind is simple in construction, easy to make, feasibility is high, can thoroughly solve blast pipe and enter benefit at water
Contract difficult casting pattern structure.
The technical solution of the utility model：A kind of casting pattern structure for thin-walled exhaust tubing product, its feature exist
In it by sprue cup, sprue, cross gate, strainer core, enter water piece, inner chamber core, rising head and casting die cavity and form；It is described to pour
Connection sprue below cup, sprue output end connection cross gate；Strainer core is set in the cross gate；The cross gate exists
Part after strainer core is divided into two cross gates, and two strands of molten iron of shunting input rising head by entering water piece by lower mould respectively；Institute
State and water piece is entered using wedge shape into water piece；The inner chamber core is placed in casting die cavity.
The sprue cup is shaped as frustum cone structure；The sprue is cylinder, its diameter and sprue cup round platform roundlet chi
It is very little identical；The cross gate cross section structure is trapezoidal；The filter residue chip architecture is standard cuboid；The rising head is shaped as cylinder
Body.
It is 250mm that the strainer core, which enters water sectional area,2, strainer core water flow is 1.5 times of discharge；After filter residue
Molten iron is divided into two strands and respectively enters two trapezoidal cross gates, and cross gate sectional area is 190mm2。
The course of work of the present utility model：
External mold template produces stream, rising head and die cavity, under in the core tripping in sand mo(u)ld die cavity of inner chamber, paying attention to during core not
The structure of die cavity and core can be destroyed；Finally play and carry out matched moulds cast after the completion of core again, complete the production of blast pipe blank.
In cast, molten iron introduces die cavity by sprue cup first, and sprue cup is shaped as frustum cone structure, and size is according to cast
Flow set；Connection sprue below sprue cup, sprue are cylinder, and its diameter is identical with sprue cup round platform roundlet size；
Molten iron is trapezoidal by entering cross gate, cross gate cross section structure after sprue；Then molten iron carries out adjusting stream filter into strainer core
Slag, filter residue chip architecture are standard cuboid, and it is 250mm to enter water sectional area2；Molten iron after filter residue is divided into two strands and respectively enters ladder
Shape cross gate, due to 1.5 times that strainer core water flow is discharge, so cross gate sectional area is 190mm2；Molten iron quilt
Subsequently into water piece is entered after shunting, it is wedge shape thin slice to enter water chip architecture；Enter water piece and molten iron is inputted into rising head from lower mould, emit the degree of lip-rounding
Shape is cylinder, and its size is set according to analog result；Last molten iron is entering water with rising head thermal center position final set, completes whole
Individual casting process.
Superiority of the present utility model：The utility model model structure enters water piece by wedge shape and is designed to entering water position
Producing effective feeding prevents shrinkage porosite, gas leakage, reduces product due to casting flaw caused by shrinkage porosite, gas leakage etc., so as to reduce manpower,
The waste of material resources, financial resources.
(4) illustrate：
Fig. 1 is a kind of structural representation for the casting pattern structure that tubing product is vented for thin-walled involved by the utility model
Figure.
Fig. 2 is Fig. 1 top view.
In figure：1 is sprue cup, and 2 be sprue, and 3 be cross gate, and 4 be that wedge shape enters water piece a, and 5 be that wedge shape enters water piece b, and 6 are
Wedge shape enters water piece c, and 7 be that wedge shape enters water piece d, and 8 be strainer core, and 9 be that wedge shape enters water piece e, and 10,11,13,15 be rising head, and 12 be casting
