Background technology
Dividing flow cone is one of key component of aluminum alloy die-casting die.At present, domestic aluminium alloy casting factory generally uses the H13 steel to make the branch flow cone.Because aluminium atom and iron atom have very strong affinity under the high temperature, therefore in the aluminium alloy compression casting process, divide flow cone very easily to corrode, do not have the effect of pushing down screen pack, influence mould and connect capabilities.Also once used the tungsten alloy split to divide flow cone in the prior art, but because bonding strength makes the split head often fracture inadequately, and the tungsten alloy price is higher, and popularization is restricted.
Summary of the invention
In order to solve branch flow cone etching problem in use, eliminate the phenomenon of frangible in using, farthest reduce cost of manufacture; Patent of the present invention provides a kind of new-type split to divide flow cone; This minute flow cone have durable, make simply, cost is low, characteristics such as anticorrosion effect excellence.
Patent of the present invention solves the technical scheme that its technical problem adopted: a kind of wheel die divides flow cone; Form by a minute flow cone main body, split head; The split head is arranged on branch flow cone main body bottom, divides the flow cone main body to adopt the 2Cr13 steel, and the split head adopts the high-temperature alloy material.
Said high-temperature alloy material is a molybdenum-base alloy.
Said high-temperature alloy material is TZM (titanium-zirconium-molybdenum) alloy.
Said high-temperature alloy material is MHC (molybdenum-hafnium-carbon) alloy.
Said high-temperature alloy material is ML (molybdenum-lanthanum-oxides) alloy.
Said high-temperature alloy material is MY (molybdenum-yttrium oxide) alloy.
Said high-temperature alloy material is TZM (titanium-zirconium-molybdenum) alloy.
Said high-temperature alloy material is MW (molybdenum-tungsten) alloy.
Said high-temperature alloy material is MCu (molybdenum-copper) alloy.
Flow cone main body, split head adopted bolt+welding fastening means in said minute.Divide the flow cone main body that the protrusion bolt is set, the split head is provided with recessed type screw thread.
The QRO90 welding wire is adopted in said welding; The argon arc welding mode; Put into preheating furnace jointly after will dividing flow cone main body and split head to tighten before the weldering and be heated to 450 ℃-480 ℃, be incubated 10-20 minute, take out the back and between 380 ℃ of-420 ℃ of temperature, weld; Slowly cool to room temperature with the asbestic blanket parcel after welding is accomplished, keep steady air current in the cooling procedure.
The invention has the beneficial effects as follows that anticorrosion effect is excellent, material cost obviously reduces than wolfram steel, adopts more solid connected mode, has guaranteed to divide the fastening durable of flow cone.
