Abstract

The invention refers to the technical field of machining, and particularly relates to a processing method of a two-tone injection model core. The processing method of the two-tone injection model core comprises the following steps of preparing materials, and using 172mmx142mmx62mm blank; rough milling appearance of a work piece, reserving 0.3 mm allowance at single side; selecting opposite faces of length and width directions as the datum references of X and Y directions; selecting the bottom face as the reference of Z direction, applying a jaw vice to mount, wherein the top face of the core is at least 30 mm higher than a jaw, and the bottom face is padded by an equal height cushion block; milling the work piece by a fine particle or ultra-fine particle hard alloy blade containing tantalum carbide or niobium carbide; applying benchwork and a milling machine to process a screw hole, cooling a water hole and tapping; performing thermal treatment and normalizing treatment; grinding on the work piece and grinding a hexagonal right angle until the shape and dimension of the drawing; linear cutting, applying a slow threading line cutting machine to cut an insert hole and a diagonal top hole of the model core. The processing machine can guarantee thee processing quality and precision of the work piece, reduce the production cost, and improve the production efficiency; moreover, the operation is simple.
