Abstract
A molding tool for producing molded parts from expandable plastic beads. The molding tool has an inner wall facing the molded part and an outer wall facing away from the molded part, between which a hollow space is formed for conveying a heating/cooling medium, and the inner and outer walls are connected to each other in some areas by spacers. Inside the spacers, through bores are formed, which convey steam, pass through the outer and inner walls, and are sealed relative to the hollow space.
Claims24
A molding tool (1) for producing molded parts from expandable plastic beads, the molding tool (1) having an inner wall (10) facing the molded part and an outer wall (12) facing away from the molded part between which a hollow space (11) is configured to convey a heating/cooling medium (K), the inner and outer walls (10, 12) are connected to each other in areas by spacers (13), inside the spacers (13) through bores (130) are formed and convey steam, wherein the through bores (130) pass through the outer and inner walls (10, 12) and are sealed relative to the hollow space (11), wherein the molding tool is produced integrally in one piece out of sintered metal and the inner wall (10) comprises an inner surface facing the molded part and a multiplicity of capillary tubes extending through the inner wall connecting the inner surface to the hollow space (11), the capillary tubes configured to divert condensate from the inner surface into the hollow space (11).
