In the design and manufacture, the framework system is the largest and most complex part.

  (1) Rack is the support around the molding machine, connecting parts, including four guide posts and other fixed parts, its steel design and manufacturing accuracy, determines the machine's life and product accuracy.

(2) mold frame machine mold forming mechanism by the dynamic mode, fixed-mode composition. In general, the dynamic mold frame to install the punch, fixed mold frame to install the die. Punch on the relatively simple, there is no attachment, die on the need to install the material gun and mandrel. There are exhaust valve on the mold frame, behind the three support plate, the support plate should be evenly distributed.

  (3) Condenser Products Before vacuum cooling, the steam needs to be cooled by the condenser. Condenser for the tube-type, is an indirect cooling, steam, cooling water is not direct contact, steam walk tube, cooling water jacket. If the steam is cooled by cooling water, it is a direct contact. Condenser is good or bad, affecting the effect of vacuum and cooling speed.
