A COOLING AND MOLDING WATER TANK FOR A PLASTIC COMPLICATED PROFILE

摘要

The invention concerns a cooling and molding water tank for a plastic complicated profile. The tank comprises a tank body composed of front block, back block, top cover of water tank, two side plates, bottom plate and plurality of foot plates, which are in bolted or hinged joint. A water inlet pipe is provided near the front end of the side plate, a water outlet pipe is provided near the back end. A vacuum valve and a vacuum gauge are provided on the top cover. Plurality of molding blocks and water collection plates are provided along the length inside the tank, and they are spaced each other . The distribution of their arrangement is closerto disperser from the front to the end. The advantage of this invention is that: the cooling water flows alternately in cycle of periphery - inner circle -periphery. It makes the compalicated profile cool homogeneously and efficiently upon. the high speed extrusion pulling and provids the profile with good molding effect and quality.
