Description
Technical field
The utility model relates to casting die field more particularly to a kind of digger travel motor casting dies.
Background technique
Running motor is shell transmission, can be directly connected with wheel or crawler driving whell, reliable operation, high-efficient.It adopts
It is the design of high-mechanic tapered roller bearing, it is made to have carrying excavator generated axial direction in work and turning completely
Power and radial force.
Running motor is solidifying in casting due to the complexity of shape, the inhomogeneities of wall thickness when taking conventional coining dies
Gu during shrinking, casting ontology forms many places thermal center, internal stress etc., lacked to generate shrinkage cavity, loose, shape recess etc.
It falls into；It pours and emits the molding die of interface one product yield not only can be improved, also formation hot riser, enhance the reliable of mold
Property.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of digger travel motor casting dies, are able to solve one
As running motor when taking conventional coining dies, due to the complexity of shape, the inhomogeneities of wall thickness, received in casting solidification
During contracting, casting ontology forms many places thermal center, internal stress etc., to lead to the problem of shrinkage cavity, loose, shape recess.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of digger travel motor casting die,
Its innovative point is: including outer housing, sand core, chill chassis and chassis snap-gauge；
The outer housing includes air hole, pours and emit interface and type chamber；The outer housing is in rotary structure, the outer housing
Air hole the one end poured the periphery for emitting interface and be uniformly located at outer housing is set, it is described pour to emit rotation is provided on the outside of interface
Rotatable card slot；The type chamber of the outer housing is connected with air hole；
The end of outer housing is arranged in the chassis snap-gauge the other end and outer housing fits closely, and is arranged on the snap-gauge of chassis
There is a chill chassis locating slot；Chill chassis locating slot location fit on the chill chassis and chassis snap-gauge, the chill
The type chamber of chassis and outer housing forms a casting space；
The type that outer housing is arranged in the sand core is intracavitary, is positioned and is connected by link slot between the sand core and chill chassis
It connects, the gap between the sand core, outer housing and chill chassis forms cast molding region.
Further, it is described pour emit on interface by rotate card slot be connected with casting runner and casting runner in be provided with pottery
Porcelain filter.
Further, the type chamber of the outer housing includes rotary table area and multi-diameter shaft area；Close pour in the rotary table area emits interface,
The rotary table area and multi-diameter shaft area are coaxially disposed；The air hole is connected with the rotary table area of outer housing.
Utility model has the advantages that
1) accelerate the solidifying of casting in the utility model by putting one piece of chill chassis in the thicker bottom of casting section thickness
Gu speed effectively controls the generation of thermal center；It is directly emitted interface by pouring molten iron is injected by casting runner, molten iron connects pouring to emit
The temperature of mouth can be higher than type chamber, form the yield rate that hot riser improves technique.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
