First claim
Opening claim text (preview).
What is claimed is: 1. A local extrusion device for high-pressure casting, comprising an extrusion core sleeve, an extrusion rod, an extrusion oil cylinder and an extrusion oil cylinder piston, characterized in that, the extrusion oil cylinder comprises the extrusion oil cylinder piston, the extrusion oil cylinder piston is connected with the extrusion rod, the extrusion rod is positioned completely within the extrusion core sleeve and the extrusion oil cylinder, and the extrusion core sleeve and the extrusion oil cylinder are fixed together and directly contact with each other, wherein the extrusion core sleeve comprises a cavity at an end in proximity to a casting, the cavity having a diameter greater than the extrusion rod. 2. The local extrusion device for high-pressure casting according to claim 1 , wherein a ratio of a cross sectional area of the extrusion oil cylinder piston to a cross sectional area of the extrusion rod is greater than 10. 3. The local extrusion device for high-pressure casting according to claim 1 , wherein a ratio of a cross sectional area of the extrusion oil cylinder piston to a cross sectional area of the extrusion rod is 10-40. 4. The local extrusion device for high-pressure casting according to claim 1 , wherein a ratio of a cross sectional area of the extrusion oil cylinder piston to a cross sectional area of the extrusion rod is 12. 5. The local extrusion device for high-pressure casting according to claim 1 , wherein a front end of the extrusion rod is higher than an end surface of the extrusion core sleeve by 4-10 mm when the extrusion oil cylinder piston is not extruded. 6. The local extrusion device for high-pressure casting according to claim 1 , wherein a gap between a lower cavity inner wall of the extrusion core sleeve and an outline of the extrusion rod is 4-10 mm. 7. The local extrusion device for high-pressure casting according to claim 1 , wherein a ratio of a cross sectional area of the extrusion oil cylinder piston to a cross sectional area of the extrusion rod is 12; when the extrusion oil cylinder piston is not extruded, a front end of the extrusion rod is higher than an end surface of the extrusion core sleeve by 10 mm; and a gap between a lower cavity inner wall of the extrusion core sleeve and an outline of the extrusion rod is 4 mm.
