The mould cavities are on the same pitch circle from the center of the axis. The rotary table is positively locked at each ninety degree turn. When the table is locked in position each station is in its position. The hopper containing pre-granulated soil is mounted stationary above the number one station. The hopper is fed by a screw conveyor from a hammer mill which breaks up the dug-out soil into a uniform granulate. This is most important for the manufacture of high quality adobe bricks. When the hopper has filled the mould cavity the carousel is turned ninety degrees and the filling process is repeated. At the same time the ram at number two station compresses the soil into a high density adobe block.

    Abstract: A briquetting machine, primarily intended for briquetting fibrous plant material, includes a pair of rotatable wheels. Each wheel has die means towards its outer periphery and the die means define a circular row of pockets in which the material is received and compressed. During rotation the wheels come together to define a nip between the wheels. To provide for a varying volume of feed of material the wheels are relatively movable to vary the size of the pockets. Furthermore the die means include male and female, overlapping dies. In the bases of the dies are located ejector members which are urged outwards to eject compacted briquettes from the dies. To compress the material prior to entry into the dies there may be a precompression channel which converges toward its outlet end, opposite converging walls of the channels being formed of compression members which move towards one another and towards the outlet end.

    Abstract: Concrete elements, such as blocks or bricks, are molded or cast by forming in a primary mold cavity a secondary mold made of a portion of a thermoplastic film which has been contacted with a flat heater surface to assure a uniformly heated film portion which is then sucked into the primary mold cavity without wrinkles and filled with concrete mix. The secondary mold with the concrete mix in it is withdrawn, for example, sucked out of the primary mold cavity well before any effective hardening of the concrete mix, so that curing and hardening takes place in the secondary mold outside the primary mold cavity. This early withdrawing is important because it avoids expansion of the curing mix in the primary mold, whereby removal from the primary mold is facilitated. Additionally, the early removal with the aid of the secondary mold assures a more efficient use of the primary molds which are used again while the hardening is still going on in the secondary mold.

  • Patent number: 4776782
    Abstract: A rotational plastic compression molding apparatus including a plurality of circumferentially spaced female molds and a plurality of circumferentially spaced male molds cooperating respectively with the plurality of the female molds. The female molds and the male molds are rotated in synchronism and thus moved round successively through a material loading zone, a compression molding zone and an article discharge zone. In the material loading zone and the article discharge zone, each said female mold and each corresponding mold are maintained in a spaced-apart inoperative relation, and in the compression molding zone, they are maintained in an approaching operative relation to define a mold space therebetween. In the material loading zone, a heat-melted plastic material is loaded in the female molds, and in the article discharge zone, the compression-molded plastic article is discharged from between each said female mold and each corresponding male mold.

  • Patent number: 4645446
    Abstract: An ejection device in a die closing unit of an injection molding machine in which the ejector piston rod, reaching from behind through the movable die carrier and into an engagement cavity in the back plate of the movable die half, is automatically engaged with, or disengaged from, the ejector plate, in the course of the movement of a die assembly into and out of the operating position, in conjunction with a mechanized die exchange procedure. A connecting socket at the extremity of the piston rod cooperates with a connecting plug on the back side of the ejector plate. A brief interruption of the transfer movement, obtained by means of a stop-start mechanism responsive to the die assembly transfer movement, allows for the piston rod to be extended into, or retracted from, the engagement cavity.
