-The blanks of Shengyuan Casting Mold mold parts are generally formed by forging. The purpose of forging is to obtain a certain geometric shape, so as to save raw materials, save processing man-hours, and reduce costs. . At the same time, through forging, the material structure can be made fine and the carbide distribution and streamline distribution are reasonable, which improves the heat treatment performance and increases the service life of the mold. For general structural parts of molds, forging usually aims to obtain a certain geometric shape. Facing the main working parts of the mold, especially the parts that require high heat treatment quality and long service life, such as the convex and concave dies of punching dies, the cavities of forging dies, plastic molds, and die-casting molds, in addition to requiring a certain geometry In addition to shape, saving raw materials, and reducing processing hours, the main purpose is to improve the performance of raw materials through forging. This is because: 1. Through repeated piercing and dialing, the density of the material itself is improved, making the internal organizational grains more uniform, thereby improving the performance of the material. 2. After the material is forged, the streamline direction or streamline bending of the material is changed, thereby also improving the mechanical properties of the material. 3. After the material is forged, the distribution of carbides inside the material is improved, the distribution level is increased, the strength and toughness of the material is enhanced, and its processing performance is improved. From this point of view, mold parts, especially main working parts, must be forged before processing. Only in this way can the mechanical properties of the material be fully utilized and the service life of the mold made be extended.
