A mold assembly and a method for changing a mold core are provided to allow the core body to be shared by exchanging the mold core separately. A mold assembly comprises a first template(23), a second template(55), a mold core(30), and a fixing pin(40). The first template is fixed to a fixed plate(20) of a molding machine, and has a first main core(27) corresponding to the external shape of product. The second template is installed on a movable plate(50), and has a second main core(57) forming the product shape together with the first main core. The mold core penetrates the inside of the first template and the first main core and shapes a part of the product. The fixing pin has an inclined pressing part(42) on the leading end, and is inserted to one side of the mold core to fix the position. The fixing pin is also inserted into the first template to press the end of the mold core in the direction separating the mold core.
