Abstract
The utility model relates to a sand-hung external chill. The two end faces of an external chill contacting with a cast are provided with grooves, and rib plates capable of hanging sand are distributed inside the grooves. The sand-hung external chill is placed in the green sand moulding process. The external chill not only can be used for moulding and embedding but also can be used for core setting during mould preparation. The utility model is free from the restriction of a moulding mode and a product structure, has the advantage of high working efficiency, is simple to manufacture, is repeatedly used and saves the cost.
Description
Technical field
The utility model belongs to casting technology field, relates to a kind of extension sand external chill that is applicable to required placement in the tide mould sand casting process.
Background technology
The method of hanging the sand external chill in the known placement of casting field is earlier facing sand to be placed on to need to place on the mould of external chill, assurance has the thick sand of 10-15mm, and then it is real that external chill is placed in the sand Chinese toon, and the sclerosis of again sand mo(u)ld being blown at last is fixed in the sand mo(u)ld external chill.But for tide mould sand casting, can not make the sand mo(u)ld sclerosis by blowing carbon dioxide or dry mode, so it is bigger to put the difficulty of dark external chill.Hang the sand external chill if place in sand mo(u)ld, the too thin then drop easily of sand is hung in the too thick effect that does not then have the acceleration cooling of the sand that the external chill surface hangs; If place bright chill, can cause the product crackle again.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of making simple, can use repeatedly, neither is subjected to the restriction of sand mold kind, is not subjected to the extension sand external chill of shape of product structural limitations again.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of extension sand external chill, be provided with groove in both ends of the surface with the contacted external chill of foundry goods, and be distributed with the gusset that can hang sand in inside grooves.
The dark 9-11mm of described groove, the outer imperial palace of groove is little.
In described groove, be covered with the water-glass sand layer.
The height of described gusset is less than the degree of depth of groove.
The beneficial effects of the utility model are: place in the tide mould sand modeling process and hang the sand external chill, external chill was not only can moulding pre-buried but also can join mould core at present, be not subjected to the restriction of sculpting method and product structure, have making and use the advantage of saving cost and high efficiency simply, repeatedly.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Among the figure: 1-gusset, 2-waterglass layer of sand, 3-external chill, 4-groove.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 and Fig. 2, a kind of extension sand external chill, cutting out the groove 4 of 10mm approximately deeply with the contacted external chill of foundry goods 3 surfaces (being both ends of the surface), groove 4 is must outer imperial palace little, inside is distributed with gusset 1 so that hang sand, in groove 4, be covered with water-glass sand layer 2 and carry out compacting, the surface is whole with the trowel equating, is exposed to then waterglass layer of sand 2 is hardened voluntarily.This hangs the sand external chill can be pre-buried when moulding, if carry out the location on the mould, also can the mode of following core place when joining mould, and can two-sidedly use, and raises the efficiency.
The height of gusset 1 is less than the degree of depth of groove 4 in Fig. 1; Waterglass layer of sand 2 faces at two ends are placed on foundry goods and need place external chill 3 positions among Fig. 2.The thickness of external chill 3 depends on needs the casting structure of Quench position size, has so just solved the tide mould sand foundry goods and need place the casting technique of hanging the sand external chill, and this chill was not only can moulding pre-buried but also can join mould core at present, and was convenient and simple, can use repeatedly.
Claims (4)
1. hang the sand external chill for one kind, it is characterized in that: be provided with groove in both ends of the surface, be distributed with the gusset that to hang sand in inside grooves with the contacted external chill of foundry goods.
