  • Publication number: 20180079122
    Abstract: The present invention enables injection by an injection device to be carried out in an early stage while obviating nozzle touch, and shortens the molding cycle of an injection stretch blow molding machine. In the present invention, an injection device 20, which is designed to perform injection when a value counted up by a timer reaches a set count value, is linked and fixed to a hot runner device 19 of an injection stretch blow molding machine 1. The count start point of the timer is set to: a stage in which a rotating plate rotates; a stage in which the rotating plate is made to stop rotating and is non-rotatably fixed; or a stage in which mold clamping of an upper mold and a lower mold begins.

  • Patent number: 8047832
    Abstract: An injection/stretch blow mold clamping mechanism comprises mold clamping shafts erected vertically movably on both sides of an injection molding operation section and extending through the lower base platen and upper base platen, hydraulic mold clamping means connected respectively to lower ends positioned within a bed of the clamping shafts, a mold clamping platen having core molds attached thereto and being fitted on the mold clamping shafts, the clamping platen being installed vertically movably between the upper base platen and a top platen, a pair of mold air cylinders connecting on both sides thereof the upper base platen and the clamping platen with each other and causing the clamping platen to move vertically with respect to the upper base platen, a mold clamping rod connected to the mold clamping platen through the top platen, and a pair of clamp members disposed on an upper surface of the top platen.

  • Patent number: 6929463
    Abstract: To realize direct and intermittent rotation of a transfer member by directly coupling the rotary part of a servo motor with a rotary shaft. A supporting board is arranged side by side with working space 3 made vacant above a machine base. The center part of a transfer member arranged on the undersurface of a supporting board 4 is coupled with a rotary shaft 7 of a relatively large diameter inserted through the center of the supporting board and mounted on a bearing. The servo motor 8 provided with the fixing part 8b inside of the rotary part 8a of the large diameter in the center of the supporting board 4 is attached to a supporting base 15 erected on the supporting board 4 via a joint 18 on the side of the fixing part 8b. The rotary part 8a is mounted on the top of the rotary shaft 7, and thereby the transfer member 6 is constructed so as to be directly rotated with the rotary shaft 7 by the servo motor 8.
