Abstract
The utility model discloses a main reducer shell shift fork hole psammitolite structure, including product local structure, shape, change the local thick structure in traditional shift fork hole. The attenuate is carried out to the part to new construction utilization three -dimensional, and product homogenizing wall thickness has lightened product weight and has realized the basic homogenization of wall thickness, eliminates the thermal center to eliminate this position shrinkage cavity defect, improve product yield and reduce the loss that shrinkage cavity, shrinkage porosite caused.
Description
Technical field
This utility model relates to automobile manufacturing field, particularly belongs to a kind of final drive casing shift fork hole sand core structure.
Background technology
Due to final drive casing shift fork hole site distance flange farther out, and connected place housing wall thickness, cannot utilize rising head that it is carried out feeding during casting, beat behind shift fork hole and at thermal center, there is shrinkage cavity and porosity in various degree, affect product and use.
Utility model content
The purpose of this utility model is to provide a kind of final drive casing shift fork hole sand core structure, utilizes three-dimensional to carry out thinning to partial structurtes, it is achieved product wall thickness substantially uniformization, eliminate thermal center, thus eliminate this position shrinkage cavity defect, improve finished product rate, reduce the loss that shrinkage cavity and porosity causes.
The technical solution of the utility model is as follows:
A kind of final drive casing shift fork hole sand core structure, include main body molding sand 1, having main reducing gear shell cavity 2 in main body molding sand 1, be positioned at increase V-type die cavity 3 at the shift fork hole outside main reducing gear shell cavity 2, the product wall thickness between die cavity 3 and main reducing gear shell cavity 2 is substantially uniform identical.
This utility model utilizes three-dimensional to carry out thinning to product partial structurtes, it is achieved wall thickness substantially uniformization, eliminates thermal center, in casting process, this position is basically identical with other position setting times, thus eliminate this position shrinkage cavity defect, improve finished product rate, reduce the loss that shrinkage cavity and porosity causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing, a kind of final drive casing shift fork hole sand core structure, includes main body molding sand 1, has main reducing gear shell cavity 2 in main body molding sand 1, being positioned at increase V-type die cavity 3 at the shift fork hole outside main reducing gear shell cavity 2, the product wall thickness between die cavity 3 and main reducing gear shell cavity 2 is substantially uniform identical.
This utility model changes the thick structure in conventional Shift Computation entry local.New construction utilizes three-dimensional thinning to locally carrying out, and product uniform wall thickness alleviates product weight and realizes wall thickness substantially uniformization, eliminate thermal center, thus eliminate this position shrinkage cavity defect, improves finished product rate and reduce the loss that shrinkage cavity and porosity causes.
