It mainly suits thermoplastic molding which can be used to shape a precision plastic part in one time. My topic is to explain the design process of the plastic injection mold on the basis of the injection mold-related knowledge, taking the hair dryer enclosure as a design model. Through analysis of the hair dryer shell molding process, I designed a double-cavity plastic mould. Those parts that deciding the geometrical shape and dimensions of the plastic mold are known as molded parts, including the design and machining process of the upper plate, the upper mold core, the lower plate, the lower mold core, and the inserting of lower mold.While designing molding components, based on the characteristics of plastic, plastic parts of the structure and use requirements, the overall layout of the cavity, the joint face, the stripping methods, design of gating system, exhaust system should be determined. Then structure of molded parts are designed, the working size of the molded parts is calculated, the key molded parts are checked for strength and rigidity. Then use Pro / E software to complete the overall design hair dryer shell mold; and finally the plastic module consultant
