  • Patent number: 12214533
    Abstract: An injection mold includes a mold insert frame having several openings extending in an axial direction (z). Each opening accommodates a mold insert encompassing a cavity, suitable to receive during operation melted plastic to form a plastic part. The several openings with the mold inserts are distributed around a center opening of the mold insert frame. A nozzle head is arranged in the center opening of the mold insert frame. A primary melt channel, extending in the axial direction (z), and per cavity a secondary melt channel are each interconnected at a dorsal end to the primary melt channel and at a distal end to a cavity by a nozzle tip attached to the nozzle head. Each mold insert includes a first cooling channel surrounding the cavity and being in fluid communication with a first cooling circuit across the mold insert frame.

  • Publication number: 20230373139
    Abstract: An injection molding device and related method includes a mold plate with at least one pocket having at least one discharge opening to discharge melted plastic from the pocket into at least one mold cavity interconnected to the pocket and a nozzle including a housing, which during operation is interconnected to the pocket. Per discharge opening a needle is arranged displaceable in an axial direction in the housing between a closed position and an open position. In the closed position the needle closes the thereto related discharge opening and is thereby preventing melted plastic from flowing from the pocket into the at least one mold cavity. In the open position, the needle releases the discharge opening such that melted plastic flows from the pocket into the at least one mold cavity. Furthermore, a melt channel is discharging into the pocket to supply melted plastic into the pocket.
