PURPOSE:To sure that a die is rationally maintained at a lower temperature or a higher temperature by insulation process in a cooling step after the intra- die molding of synthetic resin foam particles introducing a heat insulation connecting plate in the entire periphery of a connecting part between an inner mold which constitutes a cavity space and a member which forms a vapor chamber. CONSTITUTION:A foam molding machine consists of a movable die 1 and a fixed die 2 for intra-die foam molding. In addition, inner molds 1b,2b which constitute a cavity 3 and a member which forms vapor chambers 1d,2d are provided at the movable side and fixed side of the machine. The heat conductivity of heat insulation plates 1c, 2c introduced in the entire periphery of a connecting part between the inner molds 1b, 2b and the vapor chambers 1d, 2d is 1.2kcal/m.h. deg.C or lower. |
