The invention relates to a mould carrier with a lower platen and an upper platen which can be pivoted with respect to the lower platen through 90.degree. upwards, for receiving the mould halves of, more particularly, polyurethane foam moulds, with an actuating member, which can be moved linearly for opening and closing the mould carrier, and with a two-armed main lever, whose one arm is connected via a toggle lever in an articulated manner with the actuating member, and whose other arm engages the upper platen, in the case of which the toggle lever in the closed position of the mould carrier is perpendicular to the direction of movement of the actuating member for dead-center locking.

A clamp for holding together the portions of a mold used in molding solid objects from a reacting liquid such as polyurethane has a C-shaped frame which is pivotally mounted on a pedestal to swing through an arc. The C-shaped frame of the clamp consists of an integral structure having an upper jaw connected by a column to a lower jaw. The frame supports a bed, crown and platen. The bed and crown are each a plate-like member that is mounted to pivot relative to one of the jaws. The platen is mounted preferably on the bed or lower one of such members. The mold portions are mounted on the crown and platen with the parts being arranged to move so that the mold portion engage and disengage. The invention also includes a method of molding wherein the mold portions are engaged and disengaged by a process that involves pivoting at least one and preferably both of the portions relative to the C-shaped frame.

Superhydrophobic films from plastic waste and a fabrication method thereof are provided. Superhydrophobic films with variable thickness, comprising a base and top layer, can be created using semi-crystalline polymers, including virgin, recycled, or waste forms. The fabrication process utilizes 60% of total plastic waste, resulting in films with contact angles between 120° to 160°, tensile strength ranging from 1 MPa to about 70 MPa, and thickness ranging from 20 μm to about 5 mm. Superhydrophobic films may impart protective water-repellent properties against the elements.

A moulding device and a method for moulding food products from a mass of foodstuff which can be transferred by pumping are provided. The device includes a stationary frame with a revolving moulding drum assembly having a peripheral surface in which mould cavities are provided, and a mass feed device including a shoe member with a filling mouth adjoining the peripheral surface of the moulding drum assembly in order to fill said cavities with the foodstuff as they move past. In operation, the pressurized mass of foodstuff introduced into a mould cavity causes an outward force onto said shoe member. A non-revolving component is provided, concentrically supported by the moulding drum assembly, including the shoe member and an interconnected moulding drum assembly engaging counterforce element to counteract the entire outward force exerted by the pressurized foodstuff on the shoe member.

A module for a paving or building system includes at least one block of concrete and a sheet, e.g., sheet metal, having a surface area abutting the block or blocks. The sheet includes multiple openings and one or more flaps of material from one or more from the openings may be bent or otherwise shaped to extend into a concrete block and anchor the sheet to the concrete block.
摘要:
A composite piece tool used to create a composite piece. The tool includes a substrate having a substrate surface, walls disposed on the substrate and extending from the substrate surface in a thickness direction of the composite piece to define opposite locations of longitudinal composite piece ends and composite piece sides, a tooling surface disposed to occupy an entirety of a space delimited by the walls and on which the composite piece formed and a servo controller coupled to the tooling surface and configured to move the tooling surface upwardly and downwardly relative to the substrate surface and walls to form the composite piece.
摘要:
An apparatus including a mold having a top opening which leads to an inner chamber. The mold may include a first, second, third, and fourth walls, and a bottom which enclose the inner chamber. The apparatus may further include a first and/or second devices which are configured with respect to the mold to supply first and/or second mixtures of quartz and resin to the inner chamber of the mold. The apparatus may include transportation sheet which lies in the inner chamber of the mold and on an inside surface of the third wall of the mold, and which is sandwiched between the first wall and the third wall of the mold and the second wall and the third wall of the mold. The first and second devices may include means for moving the mold to allow placement of the first and/or second mixtures in specific areas of the inner chamber.
摘要:
A porous hardenable drainage element (14) is produced from a molding compound (10) of expanded plastics granulate and a bonding agent by virtue of the fact that the molding compound is received in a ladle (30) having a pouring opening (32) closed off by a mold bottom (44), the molding compound is pressurized in the ladle, the element (14) is molded from the molding compound in a mold formed by lowering of the mold bottom (44) down into an opening cross section (42) consistent with a cross section of the pouring opening (32), and the element is separated from the molding compound by mutual lateral displacement of the mold and the ladle (30).
摘要:
A system for fabricating a septic tank using an outer mold and an inner removable plug, between which hardenable fluid material is poured. Preferably, the plug and mold are positioned with respect to one another in a manner that permits a septic tank to be fabricated in a single pour.
