  • Patent number: 10967540
    Abstract: A method for moving a mold assembly from a mounted position within a concrete products forming machine includes extending an extraction assembly forwardly from a retracted position at a rear of the concrete products machine to an intermediate position so that terminal ends of the extraction assembly are positioned below a carrying surface of the mold assembly. The extraction assembly is raised at the rear portion of the concrete products machine so that the terminal ends of the extraction assembly contact and raise the carrying surface of the mold assembly up off mold mounting surfaces on the concrete products machine. The extraction assembly is then moved to a fully extended position so that the mold assembly is moved forwardly from the mold mounting surfaces to an operative position whereby the mold assembly can be removed from the extraction assembly and replaced with a replacement mold assembly.

    Abstract: A mold includes a mold core, a first cover, and a second cover. The mold core includes a cavity and a pair of elastic pieces. The pair of elastic pieces is in the cavity and divides the cavity into a first room and a second room. The first cover covers the first room of the cavity. The first cover defines a plurality of first plug holes. A first I/O can be formed in the first room by injecting a first liquid plastic material in the first room via the plurality of first plug holes. The second cover covers the first room and second room of the cavity. The second cover defines a plurality of second plug holes. A second I/O port assembly can be formed by injecting a second liquid plastic material in the first room and the second room via the plurality of second plug holes.

  • Patent number: 8709326
    Abstract: An injection molding machine may include a split mold where a gas discharge portion is formed at parting surfaces. Further, the cross-section of a flow passage of the gas discharge portion may be reduced at a predetermined timing after the start of the filling of a molding material. Since the cross-section of the flow passage of the gas discharge portion is reduced after a cavity space starts being filled with a molding material, it may be possible to make the amount of gas, which flows through the gas discharge portion, large until the cross-section of the flow passage of the gas discharge portion is reduced. It may be possible to prevent a foreign material from adhering to the inner peripheral surface of the gas discharge portion.

  • Patent number: 8623259
    Abstract: A method of injection moulding a plastics container 1 having wall(s) 2 of substantially uniform thickness using an injection mould 10 with an unsupported core 12 is disclosed. A small sliver 17 is removed from the free end of the core 12 of the mould 10 from that side of the wall which is thinnest. As a consequence on the next injection more plastic flows in that direction. Repeated optical inspection of the containers enables a balance to be achieved in which slightly asymmetric injection conditions are balanced by a slightly asymmetric container base with the result being a container with substantially uniform wall thickness.
