An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; a pressure sensor that is provided in the clamp, wherein the pressure sensor measures contact pressure that acts between the moving plate or the fixed plate and the clamp; and a controller for performing a measure to prevent detachment of the moving plate or the fixed plate based on the contact pressure.

A moving system for structures includes a linking unit located between first and second structures that can move in a first direction. A drive unit is connected to the first structure, and the first and second structures are connected. The second structure moves along the first direction when the drive unit moves the first structure along the first direction. The linking unit has a first part located on the side of the first structure and a second part located on the side of the second structure. The first and second parts line up along the first direction. The first part can shift toward the second part in a second direction different from the first direction without moving along the first direction, and the second part can shift toward the first part in the second direction without moving along the first direction.

The plurality of polyvinyl alcohol (PVA) nodule foam bars is installed at each of the plurality of rail plates such that each of a plurality of nodules of the PVA nodule foam bar aligns with the plurality of core holes and with the plurality of rail holes. The pair of end caps encloses the pair of openings of the core member.

A refrigerator door includes an outer plate that is made of metal and defines a front surface of the refrigerator door, a door liner that is coupled to the outer plate and defines a rear surface of the refrigerator door, an insulator disposed in a space defined between the outer plate and the door liner and made of polyurethane, and a foam cushion disposed at a rear surface of the outer plate and configured to expand or contract based on a change of a volume of the insulator.

A method for manufacturing a molded part while changing between multiple molds including a first ejecting step of opening a first mold and ejecting the molded part from the first mold, a checking step of checking the ejected molded part to determine if the molded part is acceptable, a first injecting step of closing the first mold and performing injection into the first mold, a second ejecting step of, where the ejected molded part is determined to be acceptable, changing the first mold to a second mold and ejecting the molded part from the second mold after the first injecting step, and a third ejecting step of, in a case where the molded part ejected in the first ejecting step is determined to be non-acceptable, not changing the first mold to the second mold and ejecting the molded part from the first mold.

An injection molding system includes a conveyor apparatus that moves a mold, and an injection molding apparatus that performs, using an injection cylinder and a screw, injection molding with the mold, wherein the improvement of the injection molding system includes at least one structure located in proximity to at least a part of the conveyor apparatus, wherein the at least one structure includes at least one element that is moveable, and wherein, when the screw is removed from the injection cylinder, the at least one element is in a position to prevent the at least one element from contacting the screw.

In a mold conveyance trolley, a trolley body includes vertical first and second side plates, first and second structural frames capable of providing rigidity in vertical planes to the front portion and the rear portion of the trolley body; and a plurality of plate members intersecting the first and second structural frames; each of the first and second structural frames includes a plurality of linking members disposed at different height positions and linked to the first and second side plates, and a plurality of steel pipe members fitted over each of the plurality of linking members and have a spacer function.

An injection molding machine for injecting a molten resin into a cavity of a molding die clamped in a die clamping unit via a nozzle formed in a heating cylinder to form a resin article includes a drive source. The drive source is configured to move the nozzle between a first position with the nozzle coupled to the molding die and a second position with the nozzle decoupled from the molding die. The drive source is also configured to pull out the molding die from the die clamping unit and to push the molding die into the die clamping unit.

An injection molding method that includes: (a) fitting an injection molding machine with an injection mold defining one or more molding cavities, with at least one mold plate provided with one or more channels for circulation of a tempering medium, (b) providing a feed of plastic material, (c) heating the molding cavities by circulating through the channels a first tempering medium, (d) injecting plastic material into the closed heated mold to fill the molding cavities, (e) cooling the molding cavities of the filled closed injection mold until at least partly solidifying the molded plastic parts by circulating through the channels a second tempering medium, (f) opening the injection mold by parting the injector plate from the ejector plate, (g) ejecting the at least partly solidified molded plastic parts by actuation of ejector pins of the ejector plate, and (h) repeating the cycle of steps (c)-(g).

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.
