Abstract
A compound type liquid lifting tube for low pressure casting is formed by integrally casting various materials. High-temperature-resistant ceramic materials are arranged on the innermost layer of the compound type liquid lifting tube, ferrous materials are arranged on the middle layer, and high-temperature-resistant fiber materials are arranged on the outermost layer. When the compound type liquid lifting tube is manufactured, the high-temperature-resistant fiber materials are coated with a layer of high-temperature-resistant cement firstly and then are brushed with a layer of high-temperature-resistant coating, and then the high-temperature-resistant ceramic materials, the ferrous materials and the high-temperature-resistant fiber materials are cast integrally. The compound type liquid lifting tube for low pressure casting integrates the advantages that the heat preservation performance of the ceramic materials and the ferrous materials are firmer, the manufacturing cost of the compound type liquid lifting tube is only one third of the manufacturing cost of a ceramic liquid lifting tube, and therefore the compound type liquid lifting tube is applicable to low pressure casting.
Description
Technical field
The utility model relates to low pressure casting field, relates in particular to the compound stalk of a kind of low pressure casting.
Background technology
Stalk is servicing unit important in aluminum alloy wheel of vehicle casting process, and aluminium liquid could enter mold cavity from holding furnace through stalk, thus shape casting blank; Simultaneously stalk is also the consumptive material in low pressure casting process, and a stalk is used 1-2 month at most, uses at least for 1 week, and the price of every stalk is between 300-800 unit, so stalk also becomes the pith in casting consumptive material.Aluminum current wheel cast industry generally adopts the stalk of two kinds of materials, and one is ceramic lift tube, and it two is irony stalk, ceramic lift tube has high insulating effect, is difficult for making the too high feature of aluminium liquid iron-holder, but expensive, fragile, phenomenon particularly easily leaks air; Although irony stalk price is lower, more firm, heat insulation effect is poor, often affect the quality of foundry goods, and easily make in aluminum solutions harmful element iron content too high, therefore, from reducing manufacturing cost, stablizing casting quality, be necessary stalk further to innovate.
Summary of the invention
The purpose of this utility model is to overcome the undesirable situation of stalk that aluminum current wheel industry is generally used, and innovates a kind of more sturdy and durable, lower stalk of while manufacturing cost.
The technical scheme that realizes above object is: the compound stalk of a kind of low pressure casting, this stalk by multiple material through integral type castable, wherein the innermost layer of stalk is resistant to elevated temperatures ceramic material, and middle one deck is ferrous material, and outermost one deck is refractory fibrous material.First at refractory fibrous material outer wrapping one deck high temperature resistant cement during making, brush again one deck high-temperature resistant coating in the above, then high temperature ceramic material, iron material, high temperature resistant composite fibre materials are made by integral type pouring type, the advantage such as heat insulating ability that this compound stalk combines ceramic material is high, iron material is firmer, and manufacturing cost only has 1/3 of ceramic lift tube, be therefore applicable to the use of low pressure casting.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the compound stalk of a kind of low pressure casting, by the high temperature ceramic material 1 of innermost layer, be positioned at the iron material 2 in the middle of it and be positioned at outermost refractory fibrous material 3 and form, existing by refractory fibrous material 3 outer wrapping one deck high temperature resistant cements during making, then brush one deck high-temperature resistant coating, high temperature ceramic material 1, iron material 2 and refractory fibrous material 3 are passed through to integral type casting complete; During installation, by the lifting hole(eyelet) 5 in the mounting disc 4 arranging, with crane, directly hang the installation that has completed stalk on board on stalk.
Claims (1)
1. the compound stalk of low pressure casting, it is characterized in that: by the high temperature ceramic material (1) of innermost layer, be positioned at its middle iron material (2) and be positioned at outermost refractory fibrous material (3) and form, existing by refractory fibrous material (3) outer wrapping one deck high temperature resistant cement during making, then brush one deck high-temperature resistant coating, by high temperature ceramic material (1), iron material (2) and refractory fibrous material (3) are by integral type casting complete, this stalk is by the lifting hole(eyelet) (5) in the mounting disc (4) arranging on it, with crane, can complete the installation on board.
