  • Patent number: 10632702
    Abstract: A molded product processing system is configured to apply a post process to a molded product molded by a compression-molding machine. The system includes modules each including a conveying mechanism configured to convey a plurality of molded products P kept aligned, and a processing mechanism confronting a travel route of the molded products conveyed by the conveying mechanism and configured to apply a predetermined post process to each of the conveyed molded products, in which upstream one of the modules and downstream one of the modules are connected to allow the molded products having gone through certain processing at the upstream one of the modules to be delivered to the downstream one of the modules and be subjected to a different predetermined processing at one of the modules.
    Type: Grant
    Filed: September 13, 2018
    Date of Patent: April 28, 2020

  • Patent number: 7462023
    Abstract: An compressive molding machine for powder material comprises an upper punch dust-proof unit 6 that surrounds a sliding part 31 of an upper punch 3 and that has expandable elasticity, and an upper seal that is arranged at a lower end portion of an upper punch holding bore 12x holding the upper punch 3 on a rotary turret 1 and that holds the upper punch 3 slidably and air-tightly, and is further provided with a communicating means 81y that makes inside of the upper punch dust-proof unit 6 communicate with outside of the upper punch dust-proof unit 6 at a time when the upper punch dust-proof unit 6 makes an abutting contact with a portion near a circumference of the upper seal 7.

  • Patent number: 7325890
    Abstract: This invention provides a glove fitting device to be removably fitted to a hermetically closable cabinet for fitting a glove to the cabinet in a manner to allow the glove to be stretched into the cabinet, the glove fitting device including: a tubular container having opposite first and second open ends, the first open end being configured to allow the glove to be replaceably fitted thereto; a lid-shaped member to be removably fitted to the second open end of the tubular container from inside of the tubular container to close the opening of the second open end substantially hermetically, the second open end becoming oriented inwardly of the cabinet when the tubular container is fitted to the cabinet; and a fixing mechanism for fixing the lid-shaped member to the second open end.

  • Publication number: 20060147574
    Abstract: An object of the compressive molding machine for powder material is to prevent a problem resulting from that the powder material splashes and the splashed powder material enters inside of an upper punch holding bore that holds the upper punch during a process of scraping the powder material after the powder material is filled into the die, or a process of compressively molding the powder material.
