Abstract

The invention provides a mold core insert for a mold, the mold and a machining process of the mold. The mold core insert comprises a product forming cavity, an ejector pin position, at least one exhaust groove and insert hanging tables. The product forming cavity is formed in one end of one side face of the mold core insert. The ejector pin position communicates with the product forming cavity andis arranged at the other end of one side face of the mold core insert. One end of each exhaust groove communicates with the product forming cavity, and the other end of each exhaust groove communicates with one end face of the mold core insert. The insert hanging tables are arranged on the two sides of one end of the mold core insert and used for positioning the mold core insert and the mold in the Z-axis direction. The machining time of the mold is shorter than that of a traditional electrode discharge machining time, mold saving and polishing are facilitated after the deep portion and the narrow gap portion of the cavity are separated, die-casting production is facilitated, and meanwhile, the quality of castings is improved, and the machining cost of the mold is reduced.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a mold core insert for a mold, a mold and a mold processing technology. Background technique [0002] The mold opening time and cost of the existing die-casting molds are concentrated on the mold core. For example, for a die-casting mold with a heat sink structure, due to the deep mold cavity and narrow gap, the graphite electrode is generally firstly molded, and then the graphite electrode is used in the electrode. The disadvantages of processing the heat sink cavity on the spark machine are: [0003] 1) EDM consumes a lot of man-hours, and EDM patterns on thin and deep cavity walls require a lot of time to save mold; [0004] 2) Due to the limitation of the mold-saving tool, the deepest part cannot be mold-saving, so that the roughness of the deeper part and the narrower gap cannot meet the requirements, that is, the mold-saving polishing is difficult; [0005] 3) ...
