摘要： A toroidal semifinished product (5) made of raw elastomeric material is semivulcanized in a semivulcanization chamber (4) defined between two half-molds (2, 3) disposed close to each other. A pressure, preferably equal to the pressure exerted by the gases generated in the semifinished product (5), is created in the mold (1a). The half-molds (2, 3) are moved apart from each other and pressure in the mold is gradually reduced, thereby giving rise to the expansion and consequent transferring of the semifinished product (5) from the semivulcanization chamber (4) to a surrounding final vulcanization chamber (6). When the inner diameter of the semifinished product (5) is larger than the inner diameter of the final vulcanization chamber (6), said chamber is closed at its inner circumferential edge and then, after possible pressure increase in the mold, at its outer circumferential edge, in order to integrally enclose the semifinished product and enable completion of the vulcanization process.

摘要： This relates to a mold for rebonding polyurethane and like plastic foam to form selected shapes. A typical shape may be a back or a seat member for an article of furniture. The mold is improved in that the bottom mold member, which is particularly designed in accordance with the desired configuration of the shape, has been formed of epoxy which is readily moldable at a low cost. The mold is also improved by providing the base plate of the mold with a ramped floor which facilitates the drainage of condensate from a lower steam chamber. The configuration of the ramped floor allows for quick removal of the condensate and serves to reduce the volume in the steam chamber thereby minimizing pressure build-up in the steam chamber. This results in lower steam pressures being used during the curing process and for a shorter curing operation. The lower steam pressure also avoids leakage of steam and water from the epoxy mold.
摘要翻译：这涉及一种用于重塑聚氨酯和类似塑料泡沫以形成选定形状的模具。典型的形状可以是用于家具制品的背部或座椅构件。改进了模具，其中根据所需形状特别设计的底部模具已经由易于以低成本模塑的环氧树脂形成。通过提供模具的底板具有斜坡地板，这有助于从下部蒸汽室排出冷凝物，也改善了模具。倾斜地板的构造允许快速去除冷凝物并且用于减小蒸汽室中的体积，从而最小化蒸汽室中的压力积聚。这导致在固化过程中使用较低的蒸汽压力和较短的固化操作。较低的蒸汽压力也可避免蒸汽和水从环氧树脂模具中泄漏。

摘要： A mold for skin covered foamed plastic molding which utilizes a middle mold to be placed between an upper mold and a lower mold, capable of avoiding an excessive amount of pressure to be exerted on the upper portion of the lower mold so that the durability of the lower mold can be improved, and preventing gaseous leakage so that the penetration of the liquid foam resin to be poured on a skin cover becomes controllable. The mold includes an upper mold to be closed over the lower mold, having extended side portions which can reach the base of the lower mold when assembled such that the extended side portions can support the upper mold by themselves.

摘要： An apparatus for producing foam-filled stud walls. The apparatus has a main frame, including a substantially vertical backplate against which the sheathing bears, a carrier unit moveable vertically on the main frame, and a dam carried on the carrier unit parallel to the backplate, moveable towards and away from the backplate. Hydraulic actuators are located between the carrier unit and main frame, and between the dam and the carrier unit, to hold the dam against the stud wall when the stud wall is positioned with its sheathing against the backplate, and to move the carrier unit and thus the dam vertically while it is so held against the stud wall.

摘要： An adapter block having fluid channels is made up of at least two parts bonded together. At least one of the parts is made up of an integral skin foam material, more specially polyurethane. A foam-molded core of this material is covered over by an integrally molded, unfoamed skin. At the faces that are to be bonded the skin is first machined away by a roughening tool. A mold for producing the adapter block is made up of two mold end parts with hollows to take up mold pins so that mold pins or stoppers may be put therein. The mold end part opposite to the end part with the pins is made of an elastically soft material. The mold pins may have concave end faces.

摘要： A mold box containing a wooden beam pattern on the bottom portion thereof is provided. An elastomer is cast in the box containing the pattern and cured therein to form an elastomeric mold having the surface configurations of the wooden beam on its inner surfaces. The elastomeric mold is then removed from the mold box and placed in a form to rigidify it. A foamable low density rigid urethane foam resin reaction mixture is then cast into the elastomeric mold and the mold closed by a cover having a depending core member. The reaction mixture is permitted to foam and cure and then the product a replica beam is removed from the mold. The skin is removed from a portion of the replica beam to aid in mounting the beam. A wood stain is applied to the replica beam and the stained surface is burnished while the stain is still wet.
