Abstract
The invention discloses a method for producing a cast steel automobile wheel hub through V process casting. The bottom of a sand core 2 is provided with a transverse inner runner, the side surface of the sand core 2 is provided with a side runner connected with the inner runner, the inner runner is connected with the bottom of the sand core 2 of the inner runner, and the inner runner is positioned in the tangential direction of the cavity of the sand core 2; and a sprue and a pouring gate are arranged in an upper sandbox, the cavity of the sand core 2 is arranged in a lower sandbox, and the parting surface of the lower sandbox is provided with a horizontal runner. Molten steel is added from the pouring gate, passes through the sprue, the horizontal runner, the side runner and the inner runner, enters the cavity, and spirally rises from bottom to top in the cavity to fill up the cavity, the negative pressures of the upper sandbox and the lower sandbox are maintained during casting, and dwelling is carried out for a certain period of time after the casting. The method effectively solves the floating of oxide dross and other impurities in the molten steel in the casting process, and makes the die cavity integrally filled.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of method of V method Foundry Production cast steel automobile wheel hub.
Background technology
Cast steel automobile hub cast wheel rim bending part because of the larger cooling of thickness comparatively slow, produce contraction after cooling and make wheel rim weakened cannot by wheel rim crooked test.Although ventilation grain can be designed on mould, escape the cooling that the mode such as channeling and blowing accelerates thicker position aluminium material, but the arrangement of its position rule of thumb arranges, and often needs correct, so then can waste wheel rim and be used as trial target.Contraction during for compensating casting after the cooling of aluminium material, by thicker for the design of the initial mould of aluminium circle, to be cast complete after process again and is removed the wheel rim that unnecessary aluminium material obtains meeting design, this method wastes too much aluminium material.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of method of V method Foundry Production cast steel automobile wheel hub is provided, efficiently solve oxidation scum and the floating of other impurity in casting process in molten steel, and mold cavity entirety is enriched all preferably.
The method of V method Foundry Production cast steel automobile wheel hub provided by the invention, comprises the following steps:
(1) core one corresponding with inner cavity of automobile hub shape and the core two corresponding with automotive hub step profile is manufactured, the bottom of core two is provided with horizontal ingate, the side of core two is provided with the side running channel communicated with ingate, ingate is communicated with the bottom of the die cavity of core two, and ingate is positioned in the tangential direction of the die cavity of core two;
(2) with the upper drag box of the bottom surface of the ring flange of automotive hub for interface making negative pressure, there is in cope the die cavity corresponding with flange profile to the top chock of automotive hub, sprue and cast gate is provided with in cope, there is in drag box the die cavity installing core two, the die joint of drag box is provided with cross gate;
(3) core under mould assembling;
(4) pour into a mould: add molten steel from cast gate, this molten steel be chosen as Cu0.6 ~ 0.8%, Ni1.0 ~ 1.5% other for iron; Molten steel tangentially enters die cavity through sprue, cross gate, side running channel and ingate, and in die cavity from the bottom up spiral to being full of die cavity, during cast, keep upper drag box negative pressure, pressurize certain hour again after casting complete;
(5) heat treating castings.
Described cast steel automobile wheel hub plate core molding sand used is clay-bonded sand, and described disk hole core molding sand used is resin sand.
The present invention efficiently solves oxidation scum and the floating of other impurity in casting process in molten steel, and mold cavity entirety is enriched all preferably.
Detailed description of the invention
Below in conjunction with an embodiment, the method for V method Foundry Production cast steel automobile wheel hub provided by the invention is described in detail.
Embodiment
The method of the V method Foundry Production cast steel automobile wheel hub of the present embodiment, comprises the following steps:
(1) core one corresponding with inner cavity of automobile hub shape and the core two corresponding with automotive hub step profile is manufactured, the bottom of core two is provided with horizontal ingate, the side of core two is provided with the side running channel communicated with ingate, ingate is communicated with the bottom of the die cavity of core two, and ingate is positioned in the tangential direction of the die cavity of core two;
(2) with the upper drag box of the bottom surface of the ring flange of automotive hub for interface making negative pressure, there is in cope the die cavity corresponding with flange profile to the top chock of automotive hub, sprue and cast gate is provided with in cope, there is in drag box the die cavity installing core two, the die joint of drag box is provided with cross gate;
(3) core under mould assembling;
(4) pour into a mould: add molten steel from cast gate, this molten steel be chosen as Cu0.8%, Ni1.5% other for iron; Molten steel tangentially enters die cavity through sprue, cross gate, side running channel and ingate, and in die cavity from the bottom up spiral to being full of die cavity, during cast, keep upper drag box negative pressure, pressurize certain hour again after casting complete;
(5) heat treating castings.
The method for casting production of cast steel automobile hub cast, efficiently solve oxidation scum and the floating of other impurity in casting process in molten steel, and mold cavity entirety is enriched all preferably.
