Semi-solid squeeze casting mould for composite bearing bush

A semi-solid squeeze casting mould for a composite bearing bush comprises a squeezing device, a fixed mould device and a movable mould device, wherein the squeezing device matched with the fixed mould device is installed in the fixed mould device, and the movable mould device is arranged on the upper side of the fixed mould device. When the semi-solid squeeze casting mould for the composite bearing bush is used, prepared semi-solid blanks are placed in a mould cavity formed by the preheated squeezing device and the fixed mould device, the movable mould device is fast descended for mould assembly, then, the squeezing device is pushed to complete the semi-solid squeeze casting forming of bearing bush material, the movable mould device is lifted for mold splitting after the forming, and the formed composite bearing bush is ejected out by lifting the squeezing device again. The composite bearing bush excellent in comprehensive performance can be formed through the semi-solid squeeze casting mould, and the semi-solid squeeze casting mould for the composite bearing bush has the advantages of being simple and reasonable in technological process, low in cost and high in efficiency.
