Abstract
The invention relates to a one-time forming manufacturing technology for an internal heat riser. The technology comprises following steps of manufacturing an inter-mould tool, an outer-mould tool and a filler plate according to the shape of the riser; nesting the filler plate into the inter-mould tool of the riser and injecting a heating material; taking the filler plate down, replacing the outer-mould tool and injecting a heat-insulating material; demoulding the riser to obtain a wet riser; and roasting the wet riser and forming in one time. The technology solves a problem that combination of the heating material and the heat-insulating material of the heat riser is not firm, and achieves the manufacturing technology of one-time forming of the heating material and the heat-insulating material. The technology is capable of guaranteeing fixed form and fixed quantity of the heating material, enhancing the strength of the riser body and guaranteeing safety in casting processes of the riser.
Description
Technical field
The present invention relates to casting field, relate in particular to a kind of one-shot forming manufacture craft of internal heat generation rising head.
Background technology
In metal casting, generally can, according to the design feature of foundry goods, the thicker large position of foundry goods, hot position of joints be used rising head, thereby utilize the molten metal in rising head to carry out feeding to foundry goods position.At blast pipe, in the production process of the cast articles such as turbine case etc. are nickelic, heat resisting steel, for guaranteeing the Modeling precision of casting blank, improve molten metal service efficiency and automaticity, use gradually in recent years core to substitute traditional hand moulding.The use of rising head, is also transitioned into insulated feeder, internal heat generation rising head from insulation situation general sand rising head, hot riser.But not identical due to foundry goods shape and material, it is different needing the heat preservation time that rising head provides.For internal heat generation rising head, existing manufacture craft is to carry out forming process twice: first make for the first time moulding heating block, then put into rising head mould and carry out rising head moulding again, finally become the embedded internal heat generation rising head of output.But this kind produced the technique that embeds exothermic riser, easily to cause heating material to be combined with insulation material insecure, causes the intensity of rising head body inconsistent, thereby cause rising head in the potential safety hazard of casting process Fracture.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcome prior art and have above-mentioned defect, and provide a kind of one-shot forming manufacture craft of internal heat generation rising head, the heating material that has solved exothermic riser is combined unstable problem with insulation material, realize heating material and the one-time formed manufacture craft of insulation material, and can guarantee the setting of heating material, quantitatively to have improved the intensity of rising head body, guarantee the safety of rising head in casting cycle.
The technical scheme that its technical problem of solution of the present invention adopts is:
An one-shot forming manufacture craft for internal heat generation rising head, is characterized in that, comprises the following steps:
A, according to rising head shape requirement, make internal mold fixture, external mold fixture and filler plate;
B, filler plate is inserted in to rising head internal mold fixture, injects heating material;
C, take off filler plate, and change external mold fixture, inject insulation material;
D, to rising head, wet rising head is obtained in the demoulding;
E, the rising head that will wet toast one-shot forming under hot conditions.
Described b step is to inject heating material process by simple and easy material-spraying device.
Described c step is to complete by core making machine the insulation material process of injecting.
Described d step is that formation wet rising head is departed from from inside and outside molded tool.
In described e step, high temperature is 150-180 ℃, and baking time is 20-50 minute.
The invention has the beneficial effects as follows: the heating material that has solved exothermic riser is combined unstable problem with insulation material, realize heating material and the one-time formed manufacture craft of insulation material, the setting that having guaranteed generates heat expects, quantitative, improve the intensity of rising head body, guaranteed the safety of rising head in casting cycle.
