Abstract
The utility model relates to a riser tube in low-pressure aluminum alloy casting, mainly consisting of a riser tube. The utility model is characterized in that the periphery of the riser tube is provided with a heat insulation layer, and the bottom part of the riser tube is provided with a filtering device. The utility model has the advantages of simple structure, good heat insulation performance, filtering function, high yield and enterprise cost lowering.
Description
Technical field
The utility model relates to a kind of stalk, the stalk of using in specifically a kind of low pressure aluminium alloy casting.
Background technology
At present, in the low pressure aluminium alloy casting, the stalk majority is a ceramic mould, and the quality of the blank internal soundness of aluminium alloy casting and temperature of aluminum liquid stable has direct relation.Along with the use of aluminium liquid in the stove, the part that stalk is exposed on the liquid level increases gradually, and it is many more to cause aluminium liquid heat to scatter and disappear, and temperature of aluminum liquid changes greatly, causes casting technique control difficulty, and percent defective is higher.The quality that how much directly has influence on product of impurity in the aluminium liquid, impurity in the aluminium liquid generally is to remove impurity with the mode that the iron wire screen pack of placing in the mould filters, this mode makes and slag point, cinder hole often occur after the cast member Surface Machining that can not satisfy the requirement of bright product, percent defective is higher.The reason of two aspects has increased entreprise cost.
The utility model content
Task of the present utility model provides a kind of simple in structure, and good heat insulating has the stalk of filtering function.
For realizing above-mentioned task, technical solution of the present utility model is:
Stalk of the present utility model, its design feature are in the stalk periphery heat-insulation layer to be set, and the bottom in stalk is provided with filter.
The utlity model has simple in structurely, good heat insulating has filtering function, and the yield rate height reduces the advantage of entreprise cost.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of stalk mainly is made of stalk 2, and at the periphery of stalk 2 bonding asbestos heat-insulation layer 1, ceramic filter 3 is installed in the bottom in stalk 2.
Claims (1)
1, a kind of stalk comprises stalk, it is characterized in that: in the stalk periphery heat-insulation layer is set, the bottom in stalk is provided with filter.
