In the mold, a slide core for molding the multi-stage fin section is placed inside the mold, and a part of the slide core is divided into multiple slide core plates that mold the top and bottom surfaces of each fin of the multi-stage fin section, respectively. Since the slide core plates are laminated and placed inside the slide core, there is no need to perform substantial deep groove machining while leaving a thin wall part, unlike with conventional slide cores of this type. A slide core with a multi-stage fin-like thin section can be made. Furthermore, since a flat slide core plate is processed, highly accurate processing and finishing can be performed satisfactorily. Therefore,
There is little resistance when removing the molded product during mold release, and damage to the molded product during mold release can be prevented. In addition, by providing very thin grooves on the top or bottom surface of each slide core plate, gas can be easily vented from the deep grooves of the slide core, and molded products may be damaged due to air being trapped when filling the material. Meat etc. can be prevented. Furthermore, if the thin wall part of the slide core is damaged due to use, it can be easily repaired by removing the slide core plate and repairing or replacing it, without having to remanufacture the entire slide core as in the case of conventional methods. can.
