Abstract
The utility model relates to a chill structure at a casting circular hole position, which is characterized in that the chill comprises a first chill and a second chill which are mutually independent and have a joint surface being an inclined plane; an outer ring surface of the combined first chill and the second chill fits with a hole wall of the casting circular hole; the joint surface of the first chill and the second chill intersects with a center axis of the casting circular hole. According to the utility model, the joint surface of the first chill and the second chill is designed to be an inclined plane and to intersect with the center axis of the casting circular hole; the utility model has a reasonable structure and can increase chill removing efficiency.
Description
Technical field
The utility model relates to the chill structure at a kind of foundry goods circular hole position, belongs to the metallurgical casting technical field.
Background technology
The chill that use at metal casting circular hole position is made by high materials of thermal conductivity such as metal, graphite and chromite sands.The graphite material chill is low, frangible because of hardness, though can break removal into pieces from foundry goods very easily, graphite costs an arm and a leg, and can cause the increase of casting process cost.For chromite sand etc. usually as Modeling Material and the cooling that is used for the thick large part of foundry goods after molding sand mixes, but cost is higher and moulding complicacy, and is difficult to recycling.And the chill price of metal material is low; And can repeat reclaim to use, be a large amount of chill modes of using of the unit of casting respectively, especially for the thick large part of foundry goods; Can place chill to improve process of setting at die cavity; Realize reducing the inner effect that forms shrinkage porosite, shrinkage cavity tendency of foundry goods, after the foundry goods moulding, chill is removed from foundry goods.The metal current chill has two kinds of structures; A kind of is overall structure; Be about to chill and process axle sleeve shape structure and be placed in the foundry goods circular hole position, but under the double action that the contraction and the chill surface roughness of molten metal process of setting exists, can cause chill to be difficult in the foundry goods circular hole, be eliminated.The chill of another kind of structure is to be put together by two half same structures; Splicing back chill lateral surface matches with the medial surface of foundry goods circular hole, but because of the central lines of the abutted surface of two blocks of chills and foundry goods circular hole or parallel, when from foundry goods removing chill; Because the moving direction of chill is parallel with the central axis of circular hole; During the cleaning foundry goods,, still exist the frictional force between two blocks of chills and the foundry goods circular hole hole wall excessive because of the existence of two chill outer surface roughness; Can cause chill from the foundry goods circular hole, to remove difficulty, the problem that the chill elimination efficiency is low.
Summary of the invention
The purpose of the utility model provides a kind of rational in infrastructure, can improve the chill structure at the foundry goods circular hole position of chill elimination efficiency.
The utility model is that the technical scheme that achieves the above object is: the chill structure at a kind of foundry goods circular hole position; It is characterized in that: chill since first chill and second chill that two separate and abutted surfaces are the inclined-plane constitute; The hole wall of first chill after the amalgamation and the outer ring surface of second chill and foundry goods circular hole matches, and the abutted surface of first chill and second chill and the central axis of foundry goods circular hole intersect.
Wherein: the outer ring surface and the inner ring surface that close after said first chill and the splicing of second chill are the conical surface.
The utility model is designed to inclined-plane and crossing with the central axis of foundry goods circular hole with the abutted surface that fits between first chill and second chill; Because the moving direction of chill is parallel with the central axis of foundry goods circular hole; After wherein a chill moves axially in two blocks of chills; Owing to all can break away from mutually between the abutted surface between two chills and two chills and the foundry goods circular hole hole wall, thereby avoid the big problem of frictional force between chill surface roughness and the foundry goods circular hole hole wall, two blocks of chills can successively be broken away from from the foundry goods circular hole easily; So can conveniently chill be taken out from the cast iron circular hole, can increase substantially casting cleaning efficient.The utility model only needs first chill and the second chill abutted surface are designed to inclined-plane and crossing, simple in structure with the circle hole centreline of cast iron, need not to increase manufacturing cost.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the invention are done further to describe in detail.
Fig. 1 is the sketch map of the utility model chill.
Fig. 2 is that the chill of the utility model is installed in the structural representation in the foundry goods circular hole.
Fig. 3 structural representation that to be the utility model remove chill in the foundry goods circular hole.
Wherein: 1-first chill, 2-central axis, 3-abutted surface, 4-second chill, 5-foundry goods circular hole.
The specific embodiment
See Fig. 1, shown in 2; The chill structure at the foundry goods circular hole position of the utility model; Chill is because two first chill 1 and second chill, 4 formations that separate and abutted surface 3 be the inclined-plane; Two blocks of chills are spliced into annular; First chill 1 after the amalgamation and the outer ring surface of second chill 4 and the hole wall of foundry goods circular hole 5 match, and promptly the endoporus wall of foundry goods circular hole 5 covers the outer ring surface of first chill 1 and second chill 4 fully, and the abutted surface 3 of first chill 1 and second chill 4 intersects with the central axis of foundry goods circular hole 52.See Fig. 1, shown in 2, first chill 1 of the utility model and second chill, 4 spliced outer ring surfaces and inner ring surface are the conical surface, the abutted surface 3 of the conical surface of foundry goods circular hole 5 and first chill 1 and second chill 4 is the inclined-plane, so can make things convenient for the cleaning of chill.See shown in Figure 3ly,, knock wherein chill when cleaning during foundry goods; During like first chill 1, first chill 1 moves along the central axis 2 of foundry goods circular hole 5 and does not receive the obstruction of any frictional force, and first chill 1 can break away from the foundry goods circular hole 5 and second chill 4 very easily; And then knock second chill 4; Because second chill 4 does not receive the obstruction of above-mentioned frictional force yet, has broken away from foundry goods circular hole 5 equally easily, the chill reset procedure is convenient and swift.
