  • Patent number: 11623379
    Abstract: A clamping device (14) comprises a pressure receiving platen (24), a stationary platen (20), a movable platen (22), a toggle mechanism (28), and a drive device (37). A first position detector (38a) detects the operation amount of the movable platen (22) based on the position of a crosshead (26); a pressure detector (35) detects the actual clamping force of a mold (19); and a second position detector (43) detects the actual position of the movable platen (22). A control portion (50) has first correction means correcting the operation amount of the movable platen (22) at the time of a minute mold opening operation based on the actual clamping force and on the set clamping force, and second correction means correcting the operation amount of the movable platen (22) at the time of the minute mold opening operation based on the operation amount of the movable platen (22) and on the position of the movable platen (22).

  • Patent number: 10730212
    Abstract: An opening/closing device (14) includes: a stationary platen (20); a movable platen (22) capable of moving toward or away from the stationary platen (20); an opening/closing mechanism (28) having a plurality of toggle links (30, 31, 32) at least one (32) of which is connected to the movable platen (22); a driving device (37) including a cross head (26) connected to at least one (30) of the toggle links and capable of moving the movable platen (22); and a control portion (50). The control portion (50) is configured to control the cross head (26) such that the movable platen (22) moves at fixed speed during fine die-opening operation.

  • Patent number: 9440388
    Abstract: A molding machine is provided with a display section with a touchpanel. A first storage section of a storage device is stored with molding conditions corresponding to molded articles each affixed with identification information. A second storage section is stored with image data on the molded articles each affixed with identification information. A third storage section is stored with memo information corresponding to the molded articles each affixed with identification information. When an image selection switch section on the display section is operated, the screen is changed to an image list screen and a plurality of images called up from the second storage section are listed. If one of these images is touched, the screen is changed to a detail display screen.
