Abstract
The invention discloses a sprue insulation device for low-pressure casting. The device comprises a liquid lifting pipe and an insulation furnace, wherein the upper part of the liquid lifting pipe extends outside the insulation furnace; a basin-shaped sprue cover is arranged at the outer side of the part, extending outside the insulation furnace, of the liquid lifting pipe; a mounting hole is formed in a furnace cover of the insulation furnace; the sprue cover is mounted in the mounting hole of the furnace cover; and the cross sectional area of the mounting hole is 12-15 times of the cross sectional area of the liquid lifting pipe. The device fully infuses the liquid lifting pipe in the high-temperature environment of a whole hearth of the insulation furnace through the basin-shaped sprue cover, uses the atmosphere temperature in the hearth for guaranteeing the temperature in the liquid lifting pipe to achieve the process requirements, solves the solidification sequence problem of the part in the casting process, achieves excellent product feeding requirement, satisfies the product quality standard, improves the production operation efficiency, and reduces the labor intensity.
Description
Technical field
The invention belongs to Foundry Production equipment field, be specifically related to a kind of low pressure casting cast gate attemperator.
Background technology
At present, in low pressure castings production, former low-pressure casting thermal insulation furnace is closed, the only reserved stalk diametric hole 100 in middle part, furnace cover of temperature-preserving furnace (6), low pressure casting machine bottom board (3) are stretched out in stalk upper end, keep stalk (4) concordant with low pressure casting machine bottom board (3) upper surface, stalk (4) upper surface and low pressure casting die (1) lower curtate are fitted, molten metal is pressed into stalk (4) filling by pressure and enters die cavity by air injection machine, and carrying out suitable pressurize, after casting solidification, die sinking is obtained qualified foundry goods.Traditional low-pressure casting thermal insulation furnace bell is enclosed construction, only reserved 100 holes, middle part, stalk is inserted in holding furnace, like this, stalk exposes the part of furnace cover of temperature-preserving furnace, temperature reduces very fast, the heat only distributed by rising in liquid process the aluminium liquid that rises at every turn maintains, and the rise liquid time of aluminium liquid in stalk is shorter, and every twice liter of liquid interprocedual interval is long, cause this position stalk cooling fast, in Die-Casting process, the solidification sequence of technological requirement is upset, this spot temperature is low to be solidified soon, aluminium liquid can not reach the feeding requirement to product at this position, the cast-internal produced is caused easily to produce serious shrinkage porosite, shrinkage cavity class defect, even foundry goods directly being taken to counterdie cannot the demoulding, production process is interrupted, the quality not only affecting product does not reach standard-required, reduce production operation efficiency simultaneously, improve labour intensity.
Summary of the invention
The object of the invention is to for prior art above shortcomings and provide
oneplant low pressure casting cast gate attemperator, the requirement that solution stalk upper-end part of driving temperature does not reach, the feeding requirement that can not meet in product press casting procedure, reach the good feeding requirement to product, meet target level of product quality, improve production operation efficiency simultaneously, reduce labour intensity.
Technical solution of the present invention is: comprise stalk, holding furnace, holding furnace is stretched out on stalk top, its arranged outside of part that stalk stretches out holding furnace has peviform to water mouth mask, the bell of holding furnace has an installing hole, water the installing hole place that mouth mask is loaded on bell, the hole cross-sectional area of installing hole is 12-15 times of the cross-sectional area of stalk.
Described middle part of watering mouth mask is outwardly, forms kidney-shaped convex body.
Described upper end of watering mouth mask is provided with locating hole, and stalk upper end is loaded on the locating hole place of watering mouth mask, and the lower end of watering mouth mask is uncovered, and uncovered shape is identical with the shape of installing hole.
Described stalk upper end is loaded on the locating hole place of watering mouth mask through seam, the mouth mask inwall that waters at locating hole place is provided with more than one ring stiffener, increases the intensity that benzvalene form waters mouth mask.
Described stalk upper surface is concordant with the upper surface of watering mouth mask.
Described lower end of watering mouth mask is provided with the flange extended radially outwardly, and waters the connecting bolt of mouth mask through being loaded on flange place and is connected with bell.
Described mouth mask upper end of watering is flush-mounted on low pressure casting machine bottom board.
Described mouth mask upper surface of watering is concordant with the upper surface of low pressure casting machine bottom board.
Described stalk is ceramic lift tube, and described bell is steel cover plate.
Described holding furnace is provided with the temperature thermocouple for measuring casting liquation.
The present invention changes and traditional rises liquid mode, watering mouth mask by benzvalene form fully to have incorporated among the hot environment of whole holding furnace burner hearth by stalk, the temperature in stalk reaches technological requirement to utilize the atmosphere temperature in burner hearth ensure that, solve the solidification sequence problem at this position in press casting procedure, reach the good feeding requirement to product, meet target level of product quality, improve production operation efficiency simultaneously, reduce labour intensity.
