Inject mold Design of ECO Base
Abstract: The product is a part of the microwave oven. The design requirements of molding material is ABS, shrinkage rate of 0.5%. The number of cavities for a mold four cavity. It is one of the supporting parts injection mold design. So the appearance of the surface quality requirements. The surface does not allow left clear traces, by using the basic theory, methods and skills of the professional knowledge and related professional, comprehensive use, according to the structure of the product and the combination of product quality requirements, has carried on the detailed design to the gate, parting line, thimble, material selection, structure, mold ejecting mechanism, molding parts, mold temperature control system, the selection of equipment etc.. Designed with the actual production levels, mould structure with advanced, reasonable technology, with high economic performance, manufacturing process and formulate the main parts, to solve specific problems of material forming process.
Key words: Mechanical design; Injection mould; ECO base
