This designs are that progress which design about Ashtray of saibao vehicle,the designs introduce present state and development circumstance of a principal penalty technology at first, and future expectation about the future of general term principal penalty industry of China plasticity high polymer, and passes analysis about product source date that form is required after is such, and understands usage of product, and analyzes technology sex of general term processing parts of plasticity high polymer, and technology with size accuracy saves that come to analyze product, and establishes correction of deformities technology of product, and understand and cause material relationship that more processing parts form is required yet except him and correction of deformities technology parameter must melt
Pass analysis about product each performance parameter, and establish plan that form is required. Model design of while is general formality obviously state : Analyze source date, finalize plan that form is required, choose installment that form is required, establish principal penalty structure, establish regular penalty river number of principal penalty, ensure the dividing regular penalty face, regular penalty river decoration, fill system and exhaust box, structural type of parts that engine mind wonder, form is required, taking out principal penalty each structure size of parts, that establish school nucleus of parts and have pushed that establish and been related technology parameter, produce outline, deliberate drawing, complete systematic design plan lastly. Modern society principal penalty industry is a manufacturing industry inside basic industry, and its development for social progress, economic growth has important sense.
Key words: Model design ;The regular penalty river ;Divide regular penalty face ;Fill system
