Abstract: In a configuration in which a guide member that guides an intermediate member to be slidably movable is provided on an upper surface of side support plates, a bending buffer portion is provided in a first region of the side support plates which is located more outward than a part of the side support plates on which the guide member is provided. The bending buffer portion is configured to be bent and deformed easier than a second region of the side support plates in which the guide member is provided.

Abstract: A mold clamping apparatus includes a fixed platen, a mold clamping cylinder, a movable platen moved by the mold clamping cylinder toward the fixed platen, and a mold opening/closing actuator for moving the movable platen or the mold clamping cylinder. The mold clamping apparatus further includes a mold thickness adjustment cylinder provided between the mold clamping cylinder and the movable platen, the mold thickness adjustment cylinder being configured to generate an axial force larger than an axial force in an expanding direction of the mold opening/closing actuator and smaller than an axial force in a contracting direction of the mold clamping cylinder.

Abstract: A vertical molding machine vertically provided with a pre-plastication injection unit where an injection unit and a plastication unit are mounted side by side. The tips of these units are linked by a connecting pipe to transfer resin plasticated by the plastication unit to the injection unit therethrough. The injection unit and the plastication unit are individually supported by respective pairs of supports standing upright above a clamping device. The injection unit has an arm member on either side thereof and a spring member is provided on the top of the arm member. The plastication unit is held on the arm member through the spring member, where the supports for the plastication unit are inserted through the arm member and the spring member.

Abstract: An electric motor type injection apparatus for a vertical molding machine which is compact in size and can be installed on a square measure limited is provided. According to this apparatus, an improper movement due to self-weight of injection mechanism members can be prevented, and deviation of a nozzle tip resulting in the cause of damage of a nozzle tip and a gate can be corrected.

Abstract: A toggle mechanism in a vertical clamping apparatus for an injection mold is supported by spring forces when operated by an electric motor in the vicinity of the mold's closing to counteract the effect of gravity on operation of the mold.
