    摘要: In a mould-closing unit (F) for an injection-moulding machine for processing plastics, at least one mould carrier (10), which can be moved in a longitudinal direction (L-L) of the mould-closing unit (F), is arranged on a machine base (14) and between itself and a further mould carrier (12) forms a mould-clamping space (C), in which parts of at least one cyclically openable and closable injection mould (M) can be received. At least one linear guide (16), arranged in the longitudinal direction (L-L) on the machine base (14), serves for guiding the at least one movable mould carrier (10) when there is movement in the longitudinal direction (L-L). The mould carrier is supported on the machine base (14) and/or the at least one linear guide (16) by way of a load take-up (18), which has above the at least one linear guide (16) an articulating region (20) for the at least one movable mould carrier (10), which region is connected to the movable mould carrier with a force fit or material bonding and the stiffness of which is greater in the longitudinal direction (L-L) than in a direction transverse to the longitudinal direction (L-L). The forces acting on the guide of the movable mould carrier during the operation of the injection-moulding machine are minimized by the load take-up (18) and/or the articulating region (20) being elliptical in cross section, with the minor axis of the ellipse extending in a direction transverse to the longitudinal direction (L-L) of the mould-closing unit (F).

    摘要: An injection molding includes: a clamping mechanism (conversion mechanism and toggle mechanism) for moving a fixed platen that retains a fixed die toward a fixed platen that retains a fixed die to bring the fixed die and the movable die into contract, and generating a clamping force therebetween; a drive source (mold opening/closing motor) for driving the clamping mechanism; a clamping force detection unit for detecting the clamping force; an elongation value detection unit for detecting an elongation value indicating the amount of elongation of a tie bar that extends as the clamping force is generated; and an abnormality determination unit for determining an abnormality in the injection molding machine on the basis of the ratio of the elongation value and the clamping force.

    摘要: This injection molding method uses an injection molding machine for two-material molding, which comprises a first mold part that is provided with a cavity and a second mold part that is provided with a cavity and is arranged in tandem with the first mold part. This injection molding method comprises: a first molding step wherein a material is injected into the cavity of the first mold part and the material in the cavity is compressed; and a second molding step wherein a material is injected into the cavity of the second mold part. A pressure, which is generated in the second mold part by injecting the material into the cavity in the second molding step, acts on the first mold part, and a compressive force is applied to the material in the cavity in the first molding step.

    摘要: The injection molding machine includes a fixed platen, a moveable platen moving forward and backward by a toggle link, a base plate supporting the toggle link, a driving part for mold clamping to operate the toggle link, a driving part for mold thickness adjustment to adjust a mold thickness, and a control unit to calculate a movement distance gap before a clamping process by controlling the driving part for mold thickness adjustment to move the base plate backward and then move the base plate forward to a target movement position based on a fold amount of the toggle link, and control the driving part for mold thickness adjustment using a value obtained by deducting the movement distance gap from the fold amount of the toggle link when producing a clamp force.
