MOLD FOR SANDWICH STRUCTURE BODY

摘要

PURPOSE:To produce a skin layer having a desired thickness at a desired part of a molded article and thereby enhance the strength of the molded body by a method wherein a mold body forming a mold cavity is provided with a cooling hole for passing a coolant therethrough at a part of the mold body corresponding to the part of the article to be enhanced in strength. CONSTITUTION:The cooling hole 7 is provided at a corner part 5b of an upper mold 5A having holes 8 for temperature regulation in the proximity of the mold cavity 4. Two kinds of stock solutions are poured into the cavity 4 formed by the upper mold 5A and a lower mold 6. Before the stock solutions are solidified through reacting with each other to form the sandwich structure body 1A, the coolant cooled to a temperature of -5-+10 deg.C is circulated through the cooling hole 7 to cool the stock solution in the proximity to the hole 7, thereby producing the skin layer 2b having a high density and the desired thickness.
