Abstract
The utility model relates to the technical filed of casting equipment, in particular to a heat preservation device of a low pressure casting machine liquid lifting pipe. The heat preservation device of the low pressure casting machine liquid lifting pipe comprises the liquid lifting pipe and a heat preservation furnace. Carbon steel rods are arranged inside the heat preservation furnace and at two sides of the liquid lifting pipe. The upper portion of the liquid lifting pipe extends out of the heat preservation furnace. A heat preservation cover is arranged outside the portion, extending out of the heat preservation furnace, of the liquid lifting pipe. A heat preservation layer is arranged inside the heat preservation cover. A gap is arranged between the heat preservation layer and the liquid lifting pipe. The heat preservation cover is in a round barrel shape. A sealing pad is arranged on the connecting portion where the lower portion of the heat preservation cover is connected with the heat preservation furnace. An opening is formed in the upper portion of the heat preservation cover and is arranged on a lower portion of a flange of the upper end of the liquid lifting pipe. A sealing pad is arranged on a connecting portion where the heat preservation cover is connected with the liquid lifting pipe. The heat preservation device of the low pressure casting machine liquid lifting pipe has the advantages of being simple and reasonable in structure, good in heat preservation effect, and capable of improving product quality.
Description
Technical field
The utility model relates to a kind of Casting Equipment technical field, specifically a kind of liquid-lifting tube of low pressure foundry attemperator.
Background technology
Air injection machine is the common apparatus of aluminum alloy low-pressure casting, can be widely used in the production of aluminium alloy castings in automobile, motorcycle, instrument, textile machine and aerospace industry.Casting mold generally is arranged on the crucible top of sealing, passed into the body of calming the anger in crucible, cause low-pressure at molten metal surface, make motlten metal by stalk rising filling casting mold and control it to solidify to produce the machine of foundry goods, therefore higher to the indices requirement at stalk position, particularly stalk is carried out to heat tracing to meet the temperature of need of production.At present, air injection machine manufacturing factory, for the heat tracing of holding furnace stalk mouth, generally adopts electric muff heater, but, because stalk top is exposed in the holding furnace outside, its serious heat loss, cause temperature to be not easy to control, affect product quality, reduced production efficiency.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure, high insulating effect, the attemperator of the liquid-lifting tube of low pressure foundry improved the quality of products in order to overcome above-mentioned defect.
The technical solution adopted in the utility model is: a kind of liquid-lifting tube of low pressure foundry attemperator, comprise stalk and holding furnace, Elema is arranged in holding furnace, the both sides of stalk, holding furnace is stretched out on stalk top, its arranged outside of part that stalk stretches out holding furnace has stay-warm case, stay-warm case inside is provided with heat-insulation layer, between heat-insulation layer and stalk, is provided with gap
.
Described stay-warm case is drum-shaped, and the junction of stay-warm case bottom and holding furnace is provided with sealing gasket, and stay-warm case top is provided with opening, and this opening is positioned at the bottom of stalk upper flanges, and stay-warm case and stalk flange connections are provided with sealing gasket.
Described stalk is ceramic lift tube, and the upper cover plate of described holding furnace is
steelcover plate.
The utility model at stalk, stretch out holding furnace its arranged outside of part stay-warm case, stay-warm case inside is provided with heat-insulation layer, be provided with gap between heat-insulation layer and stalk, this structure is carried out good insulation to stalk top, while making in stalk that liquid arrives top, temperature can anticlimax, guarantee the feeding time that casting solidification is required, improved the quality of product.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise stalk 1 and holding furnace 2, Elema 3 is arranged in holding furnace 2, the both sides of stalk 1, holding furnace 2 is stretched out on stalk 1 top, its arranged outside of part that stalk 1 stretches out holding furnace 2 has stay-warm case 4, and stay-warm case 4 inside are provided with heat-insulation layer, between heat-insulation layer and stalk 1, is provided with gap.In the present embodiment, described stay-warm case 4 is drum-shaped, the junction of stay-warm case 4 bottoms and holding furnace 2 is provided with sealing gasket, stay-warm case 4 tops are provided with opening, this opening is stretched out in stalk 1 upper end, stay-warm case 4 upper ends are positioned at the bottom of stalk 1 upper flanges, and stay-warm case 4 is provided with sealing with stalk 1 flange connections
pad.In the present embodiment, stalk 1 is ceramic lift tube 1, and the upper cover plate of holding furnace 2 is the steel cover plate, the good heat insulating of ceramic material and pollution-free to melt, and steel cover plate intensity is high, not yielding, long service life.
Due to the utility model, at stalk 1, stretch out holding furnace 2 its arranged outside of part stay-warm case 4, stay-warm case 4 inside are provided with heat-insulation layer, be provided with gap between heat-insulation layer and stalk 1, this structure is carried out good insulation to stalk 1 top, while making the interior liquid of stalk 1 arrive top, temperature can anticlimax, guarantees the feeding time that casting solidification is required, has improved the quality of product, save the energy simultaneously, reduced environmental pollution.
The utlity model has simple and reasonable for structure, high insulating effect, the characteristics of improving the quality of products.
