The invention discloses a
rapid manufacturing method of an aluminum
alloy cylinder block casting piece of an embedded cylinder sleeve. The
rapid manufacturing method comprises the following steps: obtaining 3D data of a to-be-cast aluminum
alloy cylinder block of the embedded cylinder sleeve; analyzing the 3D data; determining a process scheme; carrying out parting
processing on the 3D data; decomposing and manufacturing a mold core;
casting in a manner of mold assembling to obtain a
casting piece; cleaning the casting piece; and checking, wherein the design of an aluminum
alloy cylinder block mold core of the embedded cylinder is divided into various sand molds and sand mold groups after the 3D data are subjected to parting
processing; a left sand mold, a right sand mold, a front sand mold, a rear sand mold, a bottom sand mold, a dead head, a pouring cup and a
sprue sand mold are fabricated by adopting a PDM model direct milling technology in the decomposing and fabricating processes of the mold core; and a water sleeve core and a
crank case core
assembly are fabricated by adopting a PCM patternless casting
manufacturing technology. The method has the characteristics of being fast, accurate, efficient and economical, so that the high-quality aluminum alloy cylinder block of the embedded cylinder sleeve for an engine is manufactured; and the method is especially suitable for
rapid manufacturing of one-piece, individual, small-batch and complicated products, new product development, and the like.
