Abstract

This instruction booklet main narration radio outer covering modelsthe graduation project which carries on the mold to design.
First analyzes models the craft structure, understood models thespecification, the survey models a size, the plan models a chart, selects the ABS material, designs set of double mold holes the plastic mold. At the same time, how in detail narrated the design process to analyzemodels a product the structure, the performance, determined took shape the plan, took shape the partial designs, the guidance organization, pours the system, goes against the organization, the exhaust, thecooling system and so on, how then analyzed has chosen the moldaluminum, the mold standard
This set molding tool design combined the machine graphics, CAD, the business trip match, molding tool design, machine manufacturing the technique molding tool craft learn, the UG waits professional lesson, relating the plastics molding tool structure a design of step, detailed
introduced a set of plastics molding tool to design of all processes.
