Description
Technical field
The utility model is related to roller circle casting field more particularly to a kind of split type Centrifugal rolling ring moulds.
Background technology
Centrifugal casting is to inject liquid metals in high-speed rotating casting mold, and molten metal is made to be full of under the influence of centrifugal force
Casting mold and the technology and methods for forming casting.Centrifugal force makes liquid metals that can be full of casting mold well in radial direction and forms casting
Free Surface；Cylindrical endoporus can be obtained without core；Contribute to the exclusion of gas and field trash in liquid metals；Influence gold
The crystallization process of category, so as to improve the mechanical performance and physical property of casting.
Common roller circle centrifugal mold is generally one-piece die, is protected using coating or hanging sand, this structure exists
It is widely used in thin-walled roller circle centrifugal casting, using effect is preferable.But in heavy wall roller circle centrifugal casting, because iron water amount is big, heat
Amount is high, and roller ring mould need to be cast using thicker mould steel.In use, because roller ring mould inner surface contacts high temperature
Molten iron is brought rapidly up, and surface temperature can reach 500 DEG C or more, and roller ring mould is thicker, and heat-transfer capability is limited, in the ratio of outer surface
Surface temperature is 200-300 DEG C low, and internal and external temperature differs greatly, and the accumulation of roller ring mould internal stress, many roller ring moulds are in production heavy wall
Roller circle casting is just scrapped for tens times, causes manufacturing cost higher.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of split type Centrifugal rolling ring mould, provides a kind of use
The Centrifugal rolling ring mould of longer life expectancy.To achieve the above object, the technical solution that the utility model is taken is：It is a kind of it is split type from
Heart roller ring mould, including housing, inner sleeve, end cap and pin, the housing are set as hollow cylindrical structure, and the two of housing
End is respectively arranged with equally distributed through-hole, and the outer surface of housing is provided with symmetrical annular groove, the left end of housing inner surface
It is provided with annular protrusion, the inner sleeve is set as hollow cylindrical structure, and the left end of inner sleeve is provided with circular groove structure,
Equally distributed tapped blind hole is provided in the middle part of the right end end face of inner sleeve, the end cap is set as hollow cylinder knot
The internal diameter of structure, housing is more than inner sleeve outer diameter, and inner sleeve is arranged in housing, and inner sleeve and housing clearance fit, end cap are arranged in housing
Both ends, end cap contacts with the inner sleeve connection, and pin is arranged in the through-hole of housing, and pin is connected with end cap.
Further, it is provided with annular groove on the inside of end cap, is used for filling fire resisting material.
Further, the quantity of the through-hole of housing is set as 8, and the quantity of the tapped blind hole of inner sleeve is set as 4.
Compared with prior art, the utility model has the advantages that：Inner sleeve and housing it is easy to disassemble and safeguard, it is interior
The heat distribution of set is more uniform, and the temperature difference is smaller, reduces thermal stress, greatly improves the service life of mold, reduces
Production cost.
Description of the drawings
The utility model is described in further detail below in conjunction with attached drawing.
Attached drawing 1 is the structural schematic diagram of the utility model；
In attached drawing：1, housing, 11, positioning region, 12, auxiliary section, 13, tapped through hole, 2, inner sleeve, 21, tapped blind hole, 3, end
Lid.
Specific implementation mode
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below in conjunction with the accompanying drawings 1 and tool
Body embodiment is further described the utility model.
As shown in Fig. 1, a kind of split type Centrifugal rolling ring mould, including housing 1, inner sleeve 2, end cap 3 and pin, it is described
Housing 1 is set as hollow cylindrical structure, and the both ends of housing 1 are respectively arranged with equally distributed through-hole 13, the appearance of housing 1
Face is provided with symmetrical auxiliary section 12, and auxiliary section 12 is set as circular groove structure, and the inner surface of housing 1 is provided with positioning region
11, positioning region 11 is set as annular protrusion structure, and the inner sleeve 2 is set as hollow cylindrical structure, and the left end of inner sleeve 2 is set
It is equipped with circular groove structure, equally distributed tapped blind hole 21, the end cap 3 are provided in the middle part of the right end end face of inner sleeve 2
Be set as hollow cylindrical structure, the internal diameter of housing 1 is more than 2 outer diameter of inner sleeve, and inner sleeve 2 is arranged in housing 1, inner sleeve 2 with it is outer
Cover 1 clearance fit, inner sleeve 2 is connected by positioning region 11 and housing 1, and end cap 3 is arranged at the both ends of housing 1, end cap 3 with it is interior
Set 2 connects, and pin is arranged in through-hole 13, and pin is connected with end cap 3.
Further, the inside of end cap 3 is provided with circular groove structure, is used for filling fire resisting material.
Further, the quantity of through-hole 13 is set as 8, and the quantity of tapped blind hole 21 is set as 4.
The operation principle and the course of work of the utility model are as follows：Housing 1 and end cap 3 play assembly and match with centrifuge
