Abstract
The utility model discloses a hollow paper pouring channel. The pouring channel comprise a polystyrene pouring channel feeding port and a polystyrene pouring channel discharging port, wherein a paper tube with the same hole diameter is connected between the polystyrene pouring channel feeding port and the polystyrene pouring channel discharging port; a high-temperature resistant coating layer is coated on the outer surface of the whole pouring channel; and the thickness of the high-temperature resistant coating layer is more than or equal to 1mm. In the mass production of the polystyrene lost foam casting, the hollow paper pouring channel can be suitable for various cast pieces and has the advantages of good high-temperature resistant performance, heat insulating performance and environmental protection performance; the product quality is similar to the ceramic fibre hollow sprue, but the price is one tenth of the import pouring channel.
Description
Technical field:
The utility model relates to casting, particularly a kind of hollow papery running channel that is applicable to vertical pouring in the lost foam casting.
Background technology:
At present, external lost foam casting mostly uses ceramic running channel.The hollow sprue of ceramic fibre that U.S. lost foam casting enterprise nearly all adopts RMG company to produce, domestic many enterprises adopt the hollow sprue of foam molding.In the said goods, ceramic running channel has the advantage that improves casting quality, but costs an arm and a leg.Though foamed plastics running channel price decreases, casting quality is relatively poor, and yield rate is low.
Summary of the invention:
The purpose of this utility model provides a kind of casting quality height, the hollow papery running channel that price is low.
The technical solution of the utility model is finished as follows, it includes a polystyrene running channel charging aperture and a polystyrene running channel discharging opening, it is characterized in that: between polystyrene running channel charging aperture and discharging opening, be connected with the identical paper web in root hole footpath, on the outer surface of whole running channel, scribble one deck high-temperature resistant coating layer.The thickness of high-temperature resistant coating layer is more than or equal to 1 millimeter.
The utility model is in the polystyrene lost foam casting is produced in batches, can be applicable to the big light casting of various kenels, have high temperature resistant, heat insulating ability and the feature of environmental protection is good, product quality can compare favourably with the hollow sprue of ceramic fibre, but price is less than 1/10th of import running channel.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Further describe embodiment in conjunction with the accompanying drawings, the utility model is the improvement to the existing hollow running channel of plastic foam, mainly be tubaeform charging aperture 1 and the discharging opening 4 that has adopted the hollow running channel of polystyrene of the prior art, between the charging aperture of above-mentioned material and discharging opening, be connected with the identical paper web sprue 3 in root hole footpath, on the outer surface of whole running channel, scribble one deck high-temperature resistant coating layer 2.The thickness of high-temperature resistant coating layer is more than or equal to 1 millimeter.The material of paper web is that common yellow paper thickness is 0.8 millimeter, and length is about the 160-1500 millimeter.The utility model is poured into a mould applicable to the big light casting to various kenels, and product quality can reach every index request of the hollow running channel of ceramic fibre fully, but its cost price has only its 1/10th.
Claims (2)
1, a kind of hollow papery running channel, it includes a polystyrene running channel charging aperture and a polystyrene running channel discharging opening, it is characterized in that: between polystyrene running channel charging aperture and discharging opening, be connected with the identical paper web in root hole footpath, on the outer surface of whole running channel, scribble one deck high-temperature resistant coating layer.
2, a kind of hollow papery running channel as claimed in claim 1, it is characterized in that: the thickness of high-temperature resistant coating layer is more than or equal to 1 millimeter.
