Embodiment Construction

[0018] A method for manufacturing a graphite core of a titanium alloy casting.

[0019] The structure of the core for a titanium alloy graphite casting process is as follows figure 1 As shown, there are six hollow blade structures with space distortion on the core. A special profiling mold is designed to process this hollow blade, and the hollow blade structure of the graphite core is processed through the mold.

[0020] First, design the profiling mold according to the dimensions of the graphite core of the casting, such as figure 2 shown. Take the outer contour of the core as the inner cavity size of the mould, and offset 20mm outward according to the outer contour size of the inner cavity to obtain the outer contour size of the profiling mold. The inclusive relationship between the profiling mold and the core is as follows: image 3 shown.

[0021] Use the computer to draw the hollow blade structure of the graphite core, such as Figure 4 shown. Extend the line conne...

Abstract

The invention discloses a method for manufacturing a complex graphite mold kenel for titanium alloy castings, which includes the following steps: deviating the outer contour of the kenel of a graphite mold outward for 5-30mm to obtain the dimension of the outer contour of a copying mold, wherein the dimension of the outer contour of the kenel is the dimension of an inner cavity of the mold and the dimension of a vane part is obtained by extending the generatrix on the curved surface of the inner cavity of the vane on the kenel to the outer contour of the mold; dividing the mold into a plurality of parts to arrange the mold to be a combined structure; manufacturing the copying mold through a numerical control machine according to the dimension of the mold and the parting requirements; and mechanically manufacturing the kenel blank except the vane part through high-purity graphite according to the dimension requirement of the kenel, then mounting the kenel blank into the mold cavity and finally controlling the track of a cutter along the curved surface and the extension direction of the generatrix thereof on the vane of the mold through combined mechanical and manual method. The technique enables the inner cavity of the vane of the kenel processed according to the mold later to have high dimension precision. The technique can also be applied for manufacturing titanium alloy graphite molds with similar structural characteristics.

Description

technical field [0001] The invention relates to a manufacturing method of a casting core, in particular to a manufacturing method of a titanium alloy casting graphite core. Background technique [0002] The graphite processing casting process is an important process method in the field of titanium alloy casting technology, which is suitable for the casting and forming of single-piece and small-batch titanium alloy castings. The processing method of graphite type mainly adopts conventional mechanical processing or combined with manual processing, but it is more difficult to process graphite type with complex spatial structure. For example, the outline of the hollow blade on the graphite core of a titanium alloy casting is a twisted curve, but the generatrix of the blade forming surface is a straight line in space, so it can be processed by a CNC milling machine. However, graphite will produce a lot of dust during mechanical processing, which is very harmful to the normal ope...
