Method for processing cold-hot water pipe of turbulent flow polyurethane (PUR) foaming mold of automobile

The invention relates to a method for processing a cold-hot water pipe of a turbulent flow polyurethane (PUR) foaming mold of an automobile. The method mainly comprises the following steps of firstly performing mold flow analysis at an early stage of a mold design to find a deformation point and the deformation direction; then adding a plurality of water channels on the mold to apply cold water at an outward-deforming position of a water pipe product; and applying hot water at the inward-deforming position of the product to enable the product to produce reversible deformation, wherein the product does not deform after cooled. The method for processing the cold-hot water pipe of the PUR foaming mold of the automobile has the advantages of improving a shape-righting mode, dispensing with steps of roasting and manual shape righting, facilitating simplification of processing steps, being capable of effectively reducing the production cost and facilitating improvement of the quality of automobile turbulent flow pr
