Abstract:
A combined mold apparatus. The apparatus comprises a mold core assembly (1) and a machining assembly (2) that are manufactured by means of a 3D printing technique, wherein the mold core assembly (1) is fitted in the machining assembly (2); the mold core assembly (1) comprises two cylindrical mold core bodies (11), lug plates (12) located on two sides of each mold core body (11), and supporting members (24) located below the lug plates (12); a cut surface is formed between the upper surface and the bottom surface of each of the two lug plates (12); the included angle between the cut surface and the upper surface is θ, wherein 45°≤θ＜90°. Dimensional errors generated when the mold core assembly (1) in the mold apparatus is separated from a base plate do not affect the assembly accuracy of the mold apparatus, and the present apparatus further has the characteristics of convenient disassembly and high universality.
