    摘要: A mold (1) includes a substrate (10), a metal core (20), and a protecting film (30). The substrate is made of NEOCERAM®, a kind of material resistance to heat shock and difficult to crack. The substrate defining a cavity (101) therein and the metal core integrally fixed in the cavity. The substrate has a projecting part (102), and the top of the projecting part defines a molding cavity (103) whose surface is covered with the protecting film. A method for manufacturing such mold includes the following steps: forming a NEOCERAM cuboid; machining a projecting part at one end of the NEOCERAM cuboid; machining a molding cavity in the projecting part; defining a cavity in the cuboid and integrally fixing a metal core in the cavity; and covering the surface of the molding cavity with a protecting film made of boron nitride (BN).
