Roller injection mold design

Abstract This topic is roller injection mold design, Mold as a high value-added and technology intensive products, the level of technology already is a measure of a country's manufacturing industry an important indicator of the level, and the study of this subject will involve a number of two-dimensional and three-dimensional software applications software, such as AutoCad, as well as related software applications。 Get to train and improve in independent thinking, ability to work independently。 With the plastic products are widely used in machinery, electronics, transportation, defense, agriculture, And other industries, plastic mold, plastic mold growing demand in the national economy, the growing demand has become increasingly prominent。 At the same time this graduation project is also designed mold flow analysis and CNC machining。 Therefore, by this design will have the knowledge I had learned the consolidation and flexible use of the knowledge to solve practical problems to solve profound significance。

Key words：Roller injection  CNC machining  mold flow analysis
