Abstract

Provided is an improved wheel hub extrusion casting and forming mold. A spring (1) is arranged in a guide column (5). A big ejector rod (9) and a small ejector rod (21) are fixed to a discharging plate (23) through an ejector rod fixing plate (4). An upper mold core (10) is fixed into an upper mold fixing plate (7-1) through a connecting screw (8). A mold locking block (20-1) is fixed to the upper mold fixing plate (7-1). An inclined guide column (7) is fixed to a cavity of an upper connecting plate (6) and the upper mold fixing plate (7-1). A hydraulic cylinder assembly (14) is fixed by a fixing plate (13) and assists the combination and separation of side molds (12), a side mold guide rail (15) is connected with a pressure plate (16), and the pressure plate (16) is connected with a lower mold (20) and a bottom plate (17). A stamping guide sleeve (19-1) is connected with the bottom plate (17). According to the improved wheel hub extrusion casting and forming mold, the side molds are combined and locked through the inclined guide column, the mold locking block and the hydraulic cylinder assembly, and the problem that demolding of workblanks cannot be achieved is solved due to the spring, the discharge plate, the big ejector rod and the small ejector rod.

Description

technical field [0001] The invention relates to a mold, in particular to a extrusion casting mold for a wheel hub by a down pressure method. Background technique [0002] Squeeze casting, also known as liquid die forging, is a light alloy wheel hub forming technology between the low-pressure casting process and the forging process. A metal forming method in which metal is transformed from liquid rheological punching to crystallization and solidification into a solid blank under the external pressure of the mold. It has the advantages of good product performance and high structure density of the forging process, and has the characteristics of simple process and easy molding of the casting process. This process has high requirements on molds, and currently there is no mold available for industrial production. Contents of the invention [0003] Improved hub squeeze casting forming mold, including springs, bolts, upper plate, ejector rod fixing plate, guide post, upper conne...
