Exemplary embodiments are directed to a mold for producing hollow-cylinder-type molded parts, having an external mold portion, that determines an inner cavity of a molded part to be manufactured. The external mold portion has a first cylindrical mold, which extends in a rotationally symmetrical manner about a first axis, and a hemispherical mold having a diameter equal to a diameter of the first cylindrical mold directly adjoins one of the two ends of the cylindrical mold along the first axis, wherein a second cylindrical mold adjoins the hemispherical mold in radial alignment. The hemispherical mold has a spherical cap, the second cylindrical mold is rotatable together with the spherical cap about a second axis which is arranged at an angle with respect to the first axis, and the second cylindrical mold is arranged concentrically with respect to the second rotational axis.

A wind turbine blade manufacturing arrangement includes a first mould and a second mould connected by a hinge mechanism and presenting respective elongated first and second moulding surfaces. The first mould is adapted to be rotated from an open mould position to a mould closing position by means of the hinge mechanism in a first and a second rotation step. The hinge mechanism is arranged so as to provide for, during at least a part of the first rotation step, the first mould undergoing a combined rotational and a translational movement.

A process and a device for producing a thin-walled prophylactic, which is manufactured in a plurality of immersion stages, is disclosed. The device includes an endless conveyer belt on which an elongated cylindrical immersion tool is mounted. The process substantially consists of three immersion stages and three different immersion tubs, whereby the depths of immersion of the immersion tools substantially deviate from each other. After each immersion stage, a predetermined heat treatment of the elastic material applied to the immersion tool is carried out.

A casting mold for casting concrete elements includes a bottom surface, two edge surfaces and two end surfaces. At least one of the edge surfaces is movable for positioning at a desired distance from the other edge surface. The movable edge surface is equipped with a transfer mechanism including a driver and at least one transfer arm and a connecting rod connecting to each transfer arm. The movable edge surface is fixed in place to the bottom surface by magnetic bolts.

An adjustable culvert form facilitates fabrication of rectilinear culverts and skewed culverts that is, culverts having an angular relationship between sidewalls and span. It is particularly useful for the production of three-sided culverts. The form generally defines a parallelogram having low, vertically standing sidewalls which are interconnected at adjacent ends by hinges. The hinges may be either a conventional pair of interleaved pivots coupled by a removable pin or a unique expandable, multiple pin hinge configuration. The form is placed on a smooth horizontal surface such as a previously poured concrete slab, the surface forming the largest continuous surface of the product. The culvert is cast in an inverted orientation. The width and length of the formed product may be adjusted by the incorporation or removal of sidewall panels. Triangular sidewall panels are secured to end adjacent regions of the sidewall panels to form haunches. The walls (legs) of the culvert are formed by square or correspondingly skewed wall forms extending upwardly from the haunch panels. Various inserts may be attached to the form to mold in-situ such features as key or rail securement sites.
摘要:
A battery type mold assembly in which simple upwardly extending mold members having relief patterns on their major mold surfaces are pivotally mounted on a frame at the lower ends so as to be movable between a closed position in which a mold cavity is formed and an open position in which there is provided for the removal of a molded article therefrom. The assembly is characterized by the presence of carrier members which are, at least initially, adjustable relative to each other and the carrier members are pivotally connected to the mold members.
摘要:
A reusable form for a formed in place concrete pad positioned near a structure. The form including two spaced side beams of a predetermined length beam having first and second ends, each of the first ends are adapted to engage the structure in an abutting relation. The form further including a front beam engaging the side beams at said second ends; a pin hinge for connecting the front beam to the side beams proximate the second ends; and transverse stabilizer means mounted to and suspended above the side beams for establishing a parallel spacing between the side beams for squaring or establishing a perpendicular relation between the side beams and the front beam.
摘要:
Particle boards are currently prepared by treating the particles (e.g. wood chips) with a binder comprising an organic polyisocyanate and, optionally, a release agent and then subjecting the treated particles to a molding process involving heat and pressure. The resulting particle board will generally release well from the caul plates of the press after forming. However, it has been found that the ease of release is enhanced, particularly where the wood particles in the board are derived from hardwood, by utilizing a metal selected from magnesium and zinc in the metallic surfaces of the caul plates or platens which come into contact with the particle board during the application of heat and pressure.
