Abstract: In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

Abstract: A molding condition setting device acquires data showing a state of an injection molding machine, calculates a feature showing the state of the injection molding machine on a basis of the acquired data, and calculates a feature fluctuation rate obtained by normalizing the feature on a basis of a reference value selected from among the features according to a prescribed condition. Meanwhile, the molding condition setting device acquires information relating to a change of the value of the operation command item and stores history of the change, and generates and stores history information in which the calculated feature fluctuation rate and the information relating to the change of the value of the operation command item are associated with each other.

Abstract: An apparatus for forming a first component making up at least a part of a housing on a trimmer head and a method of using the apparatus. The housing has a rotary axis and is configured to support at least one radially projecting cutting component. The first component has a central axis. A forming unit defines at least one cavity within which a moldable material is confined to produce at least a part of a wall on the first component that extends around the rotary axis. The forming unit is configured to allow selective controlling of a quantity of a moldable material introduced into a first discrete subvolume at a first location in the one cavity to thereby allow selective controlling of a mass of a portion of the at least part of the wall formed by the moldable material in the one cavity at the first location to facilitate dynamic balancing of the housing, within which the first component is incorporated, with respect to the rotary axis.

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).
