An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

A resin fan includes a semi-molded article in which a first circular plate and blades are integrated. While the semi-molded article is retained, a composite mold is moved to a secondary molding side, a second mold is put in a first position and a third mold is moved to the first position and inserted into the first mold. An intermediate part extends over the inner surface-side of a large-bend part, and causes the end of the third mold to engage with the first mold. Next, resin is poured into a secondary forming mold, and a second circular plate is integrally molded continuous with the blades of the semi-molded article, and a fan is molded. Together with the opening of the second mold and the composite mold, the third mold and the composite mold are opened, each of the molds is moved to a second position.

A mold conveyance guide apparatus includes: a linear guide that is attached along a conveyance direction of a mold to a mold attachment surface of at least one of a fixed platen or a movable platen to which the mold is fixed; a slider that is movably attached to the linear guide; and a coupling arm that is swingably attached to the slider in a direction coming closer to or separating from the mold attachment surface and is coupled to the mold in an engageable and disengageable manner.

In an injection molding system, bolt position related information recognizing unit which recognizes an attachment position of a bolt for each attachment is provided. Based on the attachment position of the bolt, or the attachment position of the bolt and a phase of the bolt stored in the bolt position storage unit, bolt attaching and detaching unit attaches and detaches the bolt to and from the attachment. Thus, even if the position of the bolt varies in accordance with the attachment, it is possible to attach and detach the bolt by recognizing the attachment position of the bolt.

A mold conveyance roller unit includes: a rotatable roller main body on which a mold is to be placed; a roller support member that rotatably supports the roller main body; a base member to which the roller support member is attached together with the roller main body in a manner capable of vertical motion; and a resilient member that is fitted between the base member and the roller support member to elastically press the roller support member toward above the base member.

A clamping device for fastening an injection mold to a tool plate comprises an upper part and a lower part , said lower part having a mounting surface arranged flat against the tool plate. First, second, third and fourth side surfaces upstand from said mounting surface, said upper part having first, second, third and fourth side surfaces. Said upper and lower parts are connected by a first bolt having an axis of symmetry defining an axis. A resilient member is arranged in connection with the first bolt between the upper and lower parts concentrically with the bolt's axis. The first bolt has a non-threaded section such that the lower part or upper part may move along the bolt in the direction of the axis.

An optical fiber re-coating device of the invention includes an optical fiber coater that includes: a pair of glass members having grooves formed thereon; and two bases on which the respective glass members are provided, wherein at least one of the paired glass members has a cross section in a direction vertical to a mounting surface of the bases, the cross section is formed in a trapezoidal shape, the groove is provided on a short side of the trapezoidal shape, and an inclined surface of the glass member including an inclined side of the trapezoidal shape is pressed, and the glass member is thereby fixed to the base.

Additional injection modular system applicable in any process for molding parts or products by polymer injection is provided, wherein injecting one or more parts or products with a single material or a plurality of polymer materials requiring separate, simultaneous or sequential complementary injections becomes necessary in addition to the injection of a base material processed in a conventional injection machine. The system has a module configurable in both composition and dimension with optimized rheological and energy behavior which is installed between the closure assembly plates of the base machine and the mold, comprising a frame, front mold clamping plate, structure clamping plate, structure spacer blocks, at least one additional injection assembly, at least one additional injection nozzle and injection nozzle extension. The system herein can be used in the production of parts by injection processes generally designated as multi-component injection.

An injection molding device includes a housing having a door, an injection molding machine, a detection section, and a control section. The control section controls voltage applied to the mold clamping motor, and performs mold-clamping and mold-opening of the upper mold and the lower mold by either moving the injection unit and the upper mold along the vertical direction or by moving the lower mold along the vertical direction. The mold clamping device further includes a first brake section that, when application of voltage to the mold clamping motor is stopped, regulates movement of the injection unit and the upper mold in the vertical direction or movement of the lower mold in the vertical direction. When the detection section detects that the door is open or detects intrusion of foreign matter, the control section stops application of voltage to the mold clamping motor.

A conveying apparatus for conveying a mold into an injection molding machine, the conveying apparatus including an actuator for conveying the mold, a first rotating body, and a second rotating body, wherein the first rotating body and the second rotating body are configured to support a bottom surface of the mold, wherein the first rotating body and the second rotating body assist in guiding conveyance of the mold by the actuator, wherein the first rotating body is positioned closer to a fixed platen of the injection molding machine in an axial direction of the first rotating body than the second rotating body, and wherein an improvement of the conveying apparatus is that a length in an axial direction of the second rotating body is longer than a length in the axial direction of the first rotating body.
