  • Apparatus for production of cores from fluidized sands in hot boxes
    Patent number: 4452295
    Abstract: An apparatus for the production of cores from fluidized sands in hot boxes comprises individual mechanisms for joining and disjoining top and bottom sections of core boxes, which are placed beyond the confines of the latter. The joining mechanism incorporates at least two spring-loaded grapples mounted on individual shafts, fitted in satellites and positioned on a transport device, so as to carry core boxes. Located at one end of each grapple is a wedging member which co-operates with a wedging member provided on the top section of each core box. The disjoining mechanism includes stops, positioned on a support frame, and rollers mounted on the other end of each grapple for interaction with the stops.

  • Apparatus for manufacturing foundry cores
    Patent number: 4308909
    Abstract: A feature of the present invention is that an apparatus comprises an actuator of mechanisms for pressing and moving a batching chamber with a double-action cylinder whose internal ram is connected rigidly to a pressing plunger, and an external ram, to the batching chamber formed with interconnected parts having a horizontal groove at the point of their connection, the horizontal groove accommodating an additional gate with a port operated by an independent actuator. The internal ram mounts a device for adjusting the position of the pressing plunger, whereas the top head of the actuator of the mechanisms for pressing and moving the batching chamber accommodates a device for adjusting the position of the batching chamber, the top part of the batching chamber having a port providing access to the device adjusting the position of the pressing plunger.
