  • Patent number: 10245759
    Abstract: A molding machine comprises first and second non-complementary molds (20a, 20b). The first mold (20a) defines a female mold cavity (36). The second mold (20b) defines a flat molding surface (30). The first and second molds (20a, 20b) are movable between a first position in which the molds are apart and the female mold cavity (36) and the flat molding surface (30) both face upwards, and a second position in which the molds are brought together and the flat molding surface faces into and closes the female mold cavity to form a completely enclosed cavity. Each mold (20a, 20b) has a plurality of bores (22) formed through it and with an opening (24) at each end. At least two of the bores (22) are connected to each other by a block (38) positioned over the opening at one end of one bore and the opening at the end of another bore. The block (38) is formed with a groove (40) which connects the openings to each other.

The charge can be disposed on a first die of the apparatus and formed to a desired configuration defined by a recess of the die by inserting a second die or a tool into the recess. In some cases, the first die can include two portions that are adjustable in a transverse direction so that the recess can be opened by the insertion of the second die or tool. The second die or tool can be a substantially rigid member or an inflatable bladder. In either case, the charge can be disposed on the first die, formed, and then further processed on the first die, thereby facilitating indexing of the charge for each operation.

  • Patent number: 7322812
    Abstract: A transfer lock for a tabletting plant, which has a casing with side walls where at least one wall has an aperture which is adapted to be closed by a first flap which is pivotable inwardly into the interior of the casing and is adapted to be locked by a locking device operable from the interior of the casing, wherein the aperture is externally surrounded by a connection profile which is adapted to be sealingly brought together with a counter-profile of a lock channel and the flap externally has a driver profile which interacts with a counter-driver profile of a second flap mounted at the end of the lock channel when the counter-profile of the lock channel is connected to the connection profile, thus allowing to pivot the two flaps into the interior of the casing when the locking device is unlocked, which integrates the connection profile into the material of the casing wall.

  • Patent number: 7238016
    Abstract: A connecting member is formed by an upper plate portion and a side plate portion. One end of the upper plate portion is fixed to a fixed platen of an injection molding machine, and a lower end of the side plate portion is fixed to a base frame to which the fixed platen is fixed. This connecting member prevents the fixed platen from being tilted when a nozzle touch force is applied from an injection apparatus.

  • Patent number: 7179074
    Abstract: Injection molding machines must be provided with devices which ensure that the mold mounting plates when in open position cannot inadvertently close, wherein the conventional safety devices include a toothed locking bar disposed between two mold mounting plates and are provided with a ratchet mechanism, but which obstructs accessibility in the space between the two mold mounting plates, so that according with the present invention a blocking unit is disposed outside the space between two mold mounting plates for engagement of the drive unit of the closing unit to thereby prevent an inadvertent closure.

  • Patent number: 7156649
    Abstract: A fixed mold (10) has engaging pins (17) projecting towards a movable mold (20). Each engaging pin (17) includes a shaft (17A) and a large-diameter portion (17C) formed at the leading end of the shaft (17A). The large-diameter portions (17C) of the engaging pins (17) interfere with the bottom surfaces of recesses (53) of an ejector plate (50) in the process of separating the movable mold (20). Thus, the ejector plate (50) is moved forward relative to the movable mold (20) and leading ends of ejector pins (90) project from the movable mold (20).

  • Patent number: 7118366
    Abstract: A protective device for an injection unit of an injection molding machine includes a protective plate which is disposed at an outlet port of a channel of an injection nozzle. The protective plate is moveable between a shielding position, in which the outlet port is covered, and an opening position, in which the outlet port is cleared. Moving the protective plate between the shielding and opening positions is a mechanical switching mechanism which is disposed outside the channel and applies an adjusting force which acts between the protective plate and a molding tool, when the injection unit docks on the molding tool.

  • Patent number: 7052261
    Abstract: A device suitable for use by children which recycles broken crayons and other materials by melting and molding. A stationary melting pot securely retains the charge material during heating. A housing substantially surrounds the melting pot and an associated mold chamber to isolate young operators from all heated surfaces. The melting pot is charged from outside of the housing by use of a filling port. A remotely operated gate controls the flow from the melting pot to a mold. A door provides access to the mold when open and prevents access to the mold chamber when closed. A warning light glows when a heating element for the melting chamber is energized. Various safety switches interrupt power to the heating element if certain conditions are not met.

  • Patent number: 7029261
    Abstract: A dough divider including a hopper with a lid, latch assembly and press plate. The lid has an open and closed position. The latch assembly is adapted to maintain the lid in the closed position when activated and to discontinue maintaining the lid in the closed position when deactivated. The press plate is vertically slidable within the hopper, with the hopper being adapted to accept dough between the lid and the press plate. The press plate is adapted to be driven towards the lid in order to compress the dough between the press plate and the lid within the hopper. The latch assembly is automatically activated to maintain the lid in the closed position while the press plate is being driven towards the lid. The latch assembly is automatically deactivated to discontinue maintaining the lid in the closed position after the dough has been compressed and divided within the hopper.

  • Patent number: 6999823
    Abstract: Even when a power switch is turned off, the controller of an injection molding machine does not shut off a power supply immediately. The controller determines whether the present state of the injection molding machine is a previously-set confirmation-requiring state, such as a lockup state of a mold clamping unit using a toggle link mechanism, or a nozzle touch state of an injection unit. When the present state is not the confirmation-requiring state, the controller shuts off the power supply. When the present state is the confirmation-requiring state, the controller displays on a display screen a confirmation window for confirmation of power shut off. The controller shuts off the power supply in accordance with a shut-off operation performed on the basis of the confirmation window.
