Unequal-thickness deep-cavity shell mold aluminum alloy component squeeze casting device and using method thereof

Abstract

The invention discloses an unequal-thickness deep-cavity shell mold aluminum alloy component squeeze casting device and a using method thereof, and relates to an aluminum alloy component squeeze casting device and a using method thereof. The device aims to solve the technical problem that casting defects such as shrinkage cavities, shrinkage porosity and hot cracks are extremely easy to generate at hot joints in the cooling solidification process of casting of existing unequal-thickness deep-cavity shell type aluminum alloy components. The device is composed of a side core-pulling assembly, a mold cavity assembly, a mold fixed installation assembly, a mold opening and closing mechanism assembly, a component ejection mechanism assembly and a component pouring mechanism assembly. According to the device, molten metal enters a mold cavity from a pouring gate in the direction opposite to the gravity direction, and after mold filling is completed, pressure is directly applied to an unequal-thickness deep-cavity shell mold aluminum alloy component through a lower ejector rod; and in the solidifying process of the unequal-thickness deep-cavity shell mold aluminum alloy component, forced pressure supplementing is conducted on the position, with the larger wall thickness, of the unequal-thickness deep-cavity shell mold aluminum alloy component through the side core-pulling assembly, so that the defects of shrinkage porosity, shrinkage cavities and the like caused by the large wall thickness difference of complex parts are overcome.

Description

Technical field

[0001] The present invention relates to an aluminum alloy member extrusion casting apparatus and a method of use thereof.Background technique

[0002] The aluminum alloy is a problem in the field of metal material processing in the form of a metal material, which is more complicated in the shape of a metal material. It is required to have better mechanical properties. Under normal circumstances, when using traditional casting techniques, it will produce a low degree of goodness, poor mechanical properties and unstable mechanical properties. When using forging techniques, it will generate a cumbersome, waste, material waste, Cost has a problem of higher cost. Therefore, the above disadvantages can be overcome by pressing the extrusion casting. Using extrusion casting techniques can combine the advantages of casting and forging, with a shorter process, a component, a complicated, high moral performance of the shape. The extrusion casting technique is a metal in which a metal...
