  • Patent number: 10981314
    Abstract: A mold clamp control method for an injection molding machine having a toggle-type mold clamping mechanism. The mold clamp control method includes: a low-pressure mold clamping step that performs position hold control by which a crosshead is held in a set holding position in a state where a toggle link has been bent, when injection-filling is started; and a compression-press step that performs speed and position control by which the crosshead is advanced toward a set advancement position from the set holding position in a state where a first output upper limit value has been provided to a driving section. Advancement of the crosshead is continued in at least part of the compression-press step in a state where a generated output of the driving section is maintained at the first output upper limit value.

  • Patent number: 10427339
    Abstract: A mold for injection molding includes a design-surface-side mold which is capable of forming a design surface of a resin molded product and a non-design-surface-side mold which is capable of forming a mold cavity with the design-surface-side mold. A convex portion is provided in any one of the design-surface-side mold and the non-design-surface-side mold so as to protrude toward the other one. The mold for injection molding is configured to be capable of switching a first mold closing state in which the convex portion is present from any one of the design-surface-side mold and the non-design-surface-side mold over the other one and a second mold closing state in which the convex portion is not present from any one of the design-surface-side mold and the non-design-surface-side mold over the other one.

  • Patent number: 8753752
    Abstract: The present invention provides a metal plate for heat exchange which facilitates nucleate boiling and is extremely excellent in heat conductivity. In the metal plate for heat exchange of the present invention, a recess part 2 having a depth of 5 ?m or more and 10% or less of a plate thickness of the metal plate is formed. A crevasse part 7 is formed at least at a bottom corner 6 of the recess part 2. The crevasse part 7 is formed by cutting away the bottom corner 6 of the recess part 2 in the thickness direction. An angle ? formed by one cut-away surface and the other cut-away surface is 90 degrees or less. In addition, the crevasse part 7 is formed by cutting away a crystal grain 9. The recess part 2 is formed on the surface of the metal plate 1 by pressing a working part 14 formed on a surface of a working roll 12 against the surface of the metal plate 1 being carried.
