Abstract

The invention discloses a sand mold sprue cup die for casting a train wheel, which comprises a die cover and is characterized in that the die cover is of an upper core box of a float core box commonly used for casting a sand mold and is tightly pressed on a lower die box, the bottom of the lower die box is fixed on a bottom plate by a screw and is provided with a conical bulge at the inside, the conical bulge, provided with a cylindrical straight hole die at the top end, and the straight hole die are integral, venting plugs are uniformly distributed at the periphery outside of the bottom of the conical bulge, and a handle is arranged at the bottom plate. According to the sand mold sprue cup die for casting the train wheel, the fineness and strength of the contact surface between a sand mold sprue cup and steel liquid are higher, and a straight sprue of the sprue cup is round and complete and has no float sand.

Description

The sand mold runner cup mould that the casting train wheel is used
Technical field
The present invention relates to a kind of sand mold runner cup mould that train wheel is used of casting.
Background technology
Behind the rising pouring bag cast train wheel casting mold, dip in casting mold in pouring molten steel to a mini Mod with the sample spoon and to form sample, whether the chemical composition of then chemically examining sample meets quality standard with the chemical composition of knowing train wheel.The cast gate place of mini Mod is placed with sand mold runner cup, and the effect of sand mold runner cup is the molten steel of accepting from the rising pouring bag, and molten steel is imported in the mini Mod.
If the intensity of sand mold runner cup, smoothness deficiency, being subject to so the sand mold runner cup that molten steel high temperature washes away is is very easily worn and torn, the part material that punching grinds off is carried by molten steel and enters in the mini Mod, cause easily the chemical composition of the chemical composition of sample and train wheel casting mold inconsistent, be difficult to accurately judge whether the quality of train wheel is qualified.
Intensity, the smoothness that how to ensure cup is a difficult problem.To this, prior art has been made improvement to shape or the structure of sand mold runner cup, but does not disclose the making mould of sand mold runner cup.Make sand mold runner cup by hand if adopt, then the sand mold runner cup strength difference is large, the contact-making surface of cup and molten steel is coarse, and the cup down gate is not round, burr is many and floating sand is arranged, and the phenomenons such as burning into sand appear in sample after the cast easily, affect the detection accuracy of chemical composition, gently then need again grind away, impact cast rhythm makes the cast stand-by period long, easily increase the wheel percent defective, heavy then to cause judging by accident the wheel product be waste product.
Summary of the invention
The present invention provides a kind of sand mold runner cup mould that train wheel is used of casting for solving the problems of the technologies described above.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind ofly cast the sand mold runner cup mould that train wheel is used, a die cap is arranged, it is characterized in that: die cap is the upper core box of penetrating sand mold processed floating core box commonly used, and die cap is pressed on the lower diaphragm capsule, and the bottom of lower diaphragm capsule is screwed on the base plate; Lower diaphragm capsule bottom inside has the taper projection, and there is cylinder straight hole mould on the top of taper projection, and the taper projection is an integral body with the straight hole mould; Taper projection bottom periphery is evenly equipped with venting plug; Jug on the base plate.
The axis of the axis of aforementioned taper projection and lower diaphragm capsule point-blank.
The sidewall top of aforementioned straight hole die tip and lower diaphragm capsule is on same horizontal plane.
There is through hole the position that contacts with venting plug on the aforementioned base plate, the bottom outside that venting plug stretches out base plate through through hole; The bottom outside of base plate has rectangular channel, and venting plug is by the air intercommunication of rectangular channel and plate outer side periphery; Base plate has through hole on the axis.
The quantity of aforementioned lower diaphragm capsule is 4, and the venting plug quantity in each lower diaphragm capsule is 6.
The ¢ 95mm that is of a size of suitable for reading of aforementioned lower diaphragm capsule, the lower diaphragm capsule degree of depth is 22mm.
The material of aforementioned base plate, handle, lower diaphragm capsule is aluminium alloy.
Cylinder straight hole mould on the bottom of lower diaphragm capsule, sidewall, taper projection, taper are protruding forms the model of sand mold runner cup together; The upper core box of floating core box is pressed abd fixed on the lower diaphragm capsule, makes lower diaphragm capsule inner chamber be in closed state, re-use and penetrate the sand machine and penetrate sand to floating core box, sand is launched into lower diaphragm capsule inner chamber through the upper core box nozzle that floats core box, and gas is discharged through venting plug.
Abundant for ensureing, unobstructed exhaust, venting plug quantity are set to 6; Because the upper core box nozzle quantity of floating core box is more, so lower diaphragm capsule quantity is set to 4, make the upper core box nozzle of floating core box all be arranged in lower diaphragm capsule inner chamber.For fear of the upper core box venting plug of penetrating lower diaphragm capsule upper brim edge behind the sand and press stifled floating core box, according to the size of the upper core box of floating core box, the uncovered size of lower diaphragm capsule is set to ¢ 95mm.For alleviating the weight of sand mold runner cup, the lower diaphragm capsule degree of depth is set to 22mm.
Base plate, handle, lower diaphragm capsule adopt aluminum alloy material, not only light but also more shock-resistant and wearing and tearing.Handle is used for the rear demoulding of the core shooter system of penetrating and uses.
Adopt technique scheme, fineness and the intensity of the sand mold runner cup of making and molten steel contact surface are all higher, and cup down gate rounding can satisfy instructions for use without floating sand.
