Abstract£ºThe numerical control lathe called the numerical control (Numerical control, is called NC> the engine bed. It is based on the numerical control, has used the numerical control technology, is loaded with the procedure control system the engine bed. It is by the main engine, CNC, the drive, the numerical control engine bed auxiliary unit, the programming machine and other some appurtenances is composed.
This design including the main movement of engine bed design, longitudinal enters for the design, also includes the gear modulus computation and the examination, the main axle rigidity examination and so on.

Abstract

Plastic industry is in the world grows now one of quickest industry classes, but casts the mold is development quick type, The continuing development of injection mold technology demands more and more of the processes. The most important problem in the process of injection molding is undoubtedly ¡£ ¡£ the correct design of injection mold, because the molding shop has little influence£¬if any£¬ on the construction of the machine. Therefore , the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance.

This design introduced the injection takes shape the basic principle, specially single is divided the
