摘要： A mold apparatus for producing a synthetic resin foam part has a mold assembly (1) comprising a lower mold (2), an upper mold (3) removably attached to the lower mold to define a closed space, and an insert (4) removably disposed in the closed space. The insert has a partition (6) which is faced to the upper mold through a gap (11). The partition defines a chamber (7) between the insert and the upper mold. The closed space excluding the chamber constitutes a cavity (8) into which a molding compound is introduced. A pressure regulator means (21) is provided for exhausting air from the chamber (7) to keep the chamber in a subatmospheric pressure whereby air in the cavity (8) is also exhausted through the gap. A foam part is produced by feeding a synthetic resin blow molding compound into the cavity (8) under atmospheric pressure, tightly closing the mold assembly, exhausting air from the chamber and from the cavity through the gap to establish a subatmospheric pressure in the cavity, and causing the molding compound to be blow molded.

摘要： A method of molding a foamed product is carried out by using a front and a rear mold for molding a front and a rear portion of the foamed product and a core interposed between the front and rear molds. The method includes steps of pouring or spraying one of foaming stock solutions onto a molding surface of the one mold, arranging the core in the one mold and pouring or spraying the other foaming stock solution onto the core or a molding surface of the other mold. The front and rear molds are closed at a moment when a lapse of time arrives at 30-100% of a rise time of the foaming stock solution later applied. Thereafter the closed molds are maintained in a position where an angle of the closed molds relative to a horizontal plane is within a range between 90.degree. and an angle more than 0.degree.. The front and rear molds are pivotally connected to each other with their one ends by means of a pivot shaft. The core is pivotally supported with its one end by a shaft arranged in parallel to the pivot shaft. The core is formed with a through-hole and said rear mold is provided with a protrusion to be hermetically fitted in the through-hole of the core.

摘要： A polyurethane seat pad having a center seat portion and bank portions therearound is molded by using a mold defining a cavity having a center region corresponding to the center seat portion and side regions corresponding to the bank portions, placing collecting vessels of expanded polyolefin in the side regions of the mold cavity, pouring a foamable polyurethane liquid for low hardness foam into the cavity between said collecting vessels, pouring a foamable polyurethane liquid for high hardness foam into said collecting vessels, and causing the foamable liquids to expand, thereby producing a polyurethane seat pad having the collecting vessels embedded therein. The expanded polyolefin is a crosslinked polyolefin foam having an index of surface wetting of at least 36 dyne/cm. The seat pad in which the bank portions have higher hardness than the seating portion and which is fully durable against repetitive loading can be produced to the desired configuration in a stable manner.
