Abstract
The utility model discloses a chilling block device for lost foam casting of a crushing wall, which comprises a chilling block and a supporting leg. The chilling block which is a thin-wall part encircles to form a hollow cone frustum, a plurality of holes are arranged on the wall of the chilling block which is fixed onto a flask, and a sand layer is arranged between the chilling block and a foam layer. The chilling block in the device is fixed onto the flask through the supporting leg on the lower portion of the device, therefore, the chilling block can be accurately placed, and the crushing wall obtained by means of casting can be guaranteed to be uniform in wall thickness.
Description
Technical field
The utility model relates to the chill device that uses in the broken wall lost foam casting.
Background technology
Because it is very big that the liquid state of broken wall is shunk with solidification shrinkage, thus in its casting Technology Design except that need are considered enough feeding heads, often need to use a large amount of chills and control and solidify order, to reach the purpose of the shrinkage cavity of elimination foundry goods, shrinkage porosite.And the result of use of chill is not only relevant with its size, shape, and its riding position also has great influence.But in broken wall dried sand negative-pressure lost foam casting was produced, accurately laying of chill was extremely difficult, it with foam mould outer surface between be difficult to accurate location, the wall unevenness of the broken wall that casting obtains is spared.Simultaneously, because chill and foam density of modes have big difference, and the intensity of foam mould is too low, can't be held together moulding; And if chill directly contacts with the foam mould, because the defective that dope layer breaks in the cast will be caused in inevitable gap between foam mould dope layer outer surface and the chill contact-making surface.Therefore, in present broken wall lost foam casting, can't use chill.
Summary of the invention
The utility model problem to be solved provides a kind of chill device, and it can be laid when lost foam casting exactly, thereby is cast as out qualified broken wall part.
The broken wall dispellable mould casting of the utility model chill device, it is characterized in that: it comprises chill, spike; Chill is a thin-wall part, encompasses a hollow round platform, and its wall is provided with several holes; Chill is fixed on the sandbox through spike, is provided with layer of sand between chill and the foam mould.
Chill in the utility model device is fixed on the sandbox through the spike of its underpart, can realize accurately laying of chill like this, thereby the wall thickness that has guaranteed the broken wall that casting obtains is even.
Description of drawings
Fig. 1 is the utility model chill Unit Installation sketch map.
The specific embodiment
The broken wall dispellable mould casting of the utility model chill device, it comprises chill 1, spike 2; Chill 1 is a thin-wall part, encompasses a hollow round platform, and its wall is provided with several holes; Chill 1 is fixed on the sandbox 3 through spike 2, is provided with layer of sand 4 between chill 1 and the foam mould 5.
When casting, confirm chill inner wall shape and wall thickness according to the lost foam casting process designing requirement of broken wall earlier; Then (be generally between the 10-20mm according to the sand layer thickness between predefined foam mould dope layer outer surface and the chill inner surface; Look difference and the difference of the concrete shape of foundry goods, size); Adjust the intensity of cooling of chill; And carry out the necessary size correction to confirm the final shape of special chill, wherein the hole on the chill is as the drain passage of foam mould gasification product; Be fixed on disappearance sand case in through spike chill then and add the bed load consolidation; Between foam mould dope layer outer surface and chill inner surface, add layer of sand again, put the foam model type that assembles at last.When casting, liquation injects from casting gate 7, and to foam mould 5, foam mould 5 is provided with rising head 6 through interconnection, forms broken wall foundry goods after foam mould 5 disappears.
In this device, chill 1 is not directly to contact with foam mould 5, and between is provided with layer of sand 4, so overcome the defective that dope layer breaks in the cast.Wherein, chill 1 is a casting pig; Layer of sand 4 is quartz sand or special sand.
