Title: A MOLDING MACHINE FOR POLYSTYRENE ELEMENTS WITH STEAM FEED IN THE LOWER PART OF THE MOLD AND CONDENSATE DRAINAGE SYSTEM IN THE SAME PIPE
Abstract:
A molding machine for polystyrene elements basically composed of a frame and two die halves. The union of the two die halves generates the molding chamber. Once the two die halves have been locked, the polystyrene granules can be injected inside the chamber. The following injection of steam generates sintering among the granules. Steam is introduced in the fixed and moving die half in the lower part and the same pipe is also used to drain condensate, ejection, vents and chamber vacuum, that is all of process fluids. A series of valves located on the fixed part of the machine and suitably actuated control the passage of the process fluids in the same pipe.
