Title The Design of Plastic Injection Mould of Laxiantao
Abstract
The plastic injection mould of laxiantao based on practical engineering was designed. In the design the plastic injected and formed with (CH) 2, and there were two cavities in the mould. The technology of manufacture particularly was analyzed. The technology parameter of the plastic, the forming method, forming equipment in the course of using the mould and the collectivity blue print of mould design were confirmed. The collectivity structure of the mould and the particular structure of all the work section were analyzed and resolved. Especially, side-loosing core and constitute cores structure, conducts some necessary dimension calculate and intension inspect were adopted. The irrigate system、shuck institution and temperature adjust system were also designed. The triaxiality models and the schedule drawings of the mould were done. Final process cards of most parts were designed, and all the work of the mould design was finished.
Through this design, the knowledge of more basic and specialty was synthetically applied. The system of knowledge we learned was intensified. The methods and skills of designing plastic mould with Solid Edge were mastered, the design of engineering application was known well.
