Description

Technical Field

[0002] Shoe molds typically refer to molds for sports shoes, beach shoes, slippers, rubber shoes, and other footwear. Molds refer to the various molds and tools used in industrial production to produce the desired product through methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting, stamping, and stretching. Sole molds require different designs depending on the material. Molds for major materials such as RB, EVA, and TPR are the most widely used. Generally speaking, shoe molds are injection molds, but there are exceptions, such as CMEVA, which uses a combination of injection molding and cold pressing, and some are blow molded. The shoe mold design process primarily involves: 1. Pattern development, primarily determining the die plate, exterior plate, and sidewall curves; 2. 2D engineering drawings; 3. 3D model creation; 4. CAM programming; 5. 5. Carving the wooden mold, among other things. Key factors in shoe mold design include: 1. Mold material, specifications, weight, and number of cavities; 2. Determining the orientation of the parting surface; and 3. Design of the feed port and runners. 4. Exhaust method, exhaust hole or vacuum channel design, etc.;
