According to the mold structure, materials, use functions and mold manufacturing methods, it can be divided into several categories or varieties. 1 Punching die (punching die) Punching die (punching with little or no waste, trimming, smooth punching, deep hole punching precision die, etc. ), bending die, drawing die, single-process die (blanking, bending, drawing, forming, etc. ), compound die and progressive die; Stamping die for automobile panel, combined stamping die, stamping forming of motor silicon steel sheet 2 Plastic molding die, compression die, extrusion die and injection die (vertical, vertical and angular injection dies); Thermosetting plastic injection mold, extrusion molding mold (pipe, flat head, etc. ), foam molding mold, low-tool tool foam injection mold, blow molding mold and other plastic products forming plus Huangyan process (thermosetting and thermoplastic molding compounds) 3 Hot chamber die casting machine die casting mold, vertical cold chamber die casting machine die casting mold, official cold chamber die casting machine die casting mold, full vertical die casting machine die casting mold, non-ferrous metals (zinc, aluminum, copper, aluminum, aluminum, aluminum, ferrous metal die casting mold non-ferrous metals Metal parts are formed, such as cold heading dies, extrusion dies, wire drawing dies and liquid forging dies for various fasteners, and metal models for casting various metal parts are forged and extruded. Metal casting forming process 6 powder metallurgy mold forming mold: manual mold: solid one-way pressing and solid two-way pressing manual mold; Solid floating die moving die: large-section solid floating die, pole palm one-way die, sleeve one-way die, sleeve floating die forming die: manual die: radial forming die, sleeve full forming die with outer step, spherical part forming die and other moving dies: automatic forming die for solid parts without step, semi-automatic forming bag with sleeve pull rod, sleeve through automatic forming die, sleeve with outer step, sleeve automatic forming die with outer spherical surface, etc. The main die electro-machining equipment is used for copper-based and iron-based powder products; Mechanical parts, tool materials and easily-heated parts of products, etc. 7. Glass product mold Blow-blow molding bottle and jar mold, pressure-blow molding bottle and jar mold, glassware mold and other glass product molding processes 8. Rubber molding mold, rubber extrusion mold and rubber product injection mold. Rubber tire mold, O-ring rubber mold, etc. Ceramic molds, metal molds of various ceramic utensils, etc. 10 economic mold for molding process of ceramic products (simple mold)
