Abstract: A clamping device for injection-molding machine includes a high-speed screw rod unit having a nut element screwed thereto and a movable mold holder connected to a front end thereof, a clamping screw rod unit screwed to a rear end of the nut element and connected to a transmission assembly, a pre-pressing unit adjustably tightened to the clamping screw rod unit for the latter to generate a pre-pressure against the nut element, and a braking unit adapted to brake the nut element. When the nut element is not braked, the high-speed screw rod unit is driven by the transmission assembly to move forward at high speed for closing mold. And, when the nut element is braked and the clamping screw rod unit is driven by the transmission assembly to rotate relative to the nut element, the nut element is linearly pushed forward to generate a high-pressure clamping force during closing mold.

Abstract: A parallelism adjustment device applicable to nano-imprint lithography has an imprint unit, a carrier unit, a parallelism adjustment mechanism, and a driving source. The imprint unit has a first molding plate and an imprinting mold mounted on the first molding plate. The carrier unit has a second molding plate and a substrate mounted on the second molding plate. The parallelism adjustment mechanism has an enclosed resilient film and a fluid filled therein, and is coupled to at least one of the first and second molding plates. The driving source drives at least one of the imprint unit and the carrier unit to form contact between the mold and the moldable layer. The parallelism adjustment device is pressed via the contact to adjust parallelism for the imprint mold and the substrate and uniformly distributes the pressure between the mold and the substrate, making the molding quality of nano-imprint lithography significantly improved.

Abstract: A uniform pressing apparatus used in nanoimprint lithographic process is proposed, including a housing having a first flange; a first carrier unit for carrying an imprint mold and having at least one second flange freely attaches to the first flange; a second carrier unit for carrying a substrate; at least one uniform pressing unit mounted on a imprint force transmission path; and a power source driving at least one of the housing and the second carrier unit to allow a contact to be formed between the mold and the moldable layer. Therefore, the nanoimprint lithographic process is achieved with good parallelism between the substrate and the mold and with uniform pressure distribution.

Abstract: A nozzle-contacting device of an injection molding machine includes an injection module and a mold-holding structure both set on a lathe bed. The injection module sets a nozzle at a front end thereof and a nozzle-adjusting device, which is fixed and locked on the lathe bed, at a back end thereof. The mold-holding structure includes a mold-clamping structure and an adjusting plate, wherein the mold-holding structure sets plural tie rods. A mold is fixed and locked on the adjusting plate which is sleeved on plural tie rods, and one or more driver set on a front end of a dead plate penetrates the dead plate to connect to the adjusting plate. Furthermore, the dead plate has a perforation set on a centre thereof corresponding to a position of the nozzle of the injection module.

Abstract: The present invention is a force detecting controlling device of a screw for an injection molding machine, which adopts a load cell to be as a force sensor for injection, holding pressure and back pressure. The load cell arranged on a rear fixed plate directly detects a force applied onto a ball screw nut. Because the ball screw nut is fastened on the load cell, and the load cell is fixed on the rear fixed plate, further, force on a ball screw is directly transmitted to the ball screw nut, therefore, a total value of the force on the ball screw, force produced by back pressure and friction among mechanical parts are equal to a force value of the ball screw nut applying onto the load cell. To accurately control the injection pressure is the basic requirement for precision injection, that is, the injection force may be very truthful.

Abstract: An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw. Stationary parts of the motors are fastened on a frame and forward-backward moving unit, not moving during injection and metering. Due to the arrangement of the moving parts and the injection screw on a single axis, moving parts are lessened, and transmission losses are minimized. Since the number of structural parts is low, only the moving parts of the motors move during injection while the stationary parts thereof remain at rest, thus greatly reducing inertia.

Abstract: A cleat holder is fixed to an underside of footwear and comprises a base and a hub projecting from. The hub includes a plurality of lobes on an outer periphery thereof and a screw-threaded bore. Grooves are defined in a side of the base, each groove having a portion extending to an indentation between two adjacent lobes. A shoe cleat comprises a cleat body and a screw-threaded spigot projecting from the cleat body. The screw-threaded spigot is releasably engageable with the screw-threaded bore of the cleat holder through rotary insertion. Protrusions are formed on a side of the cleat body and located around the screw-threaded spigot. Each protrusion of the shoe cleat is retained in place by an associated groove and an associated indentation of the cleat holder when the screw-threaded spigot is in the engaged position.

The rear plate is disposed on the base plate. The rear plate is disposed between the lateral plates. The top plate is disposed on the rear plate and the lateral plates. The door plate is disposed between the top plate and the base plate. A plurality of connection plates fasten the top plate and the lateral plates together. A plurality of connection bars fasten the base plate and the lateral plates together.

Abstract: A retaining/fixing device is disclosed. It is applicable in a container and a construction site and can be used as a jack. The retaining/fixing device mainly includes a base seat, an outer tube, an inner rod, a rack, a handle, a first claw, a second claw, a resilient plate and a stopper pin. By means of reciprocally lifting and depressing the handle, the outer tube is displaced relative to the inner rod so that the retaining/fixing device is forcedly tightened to a necessary extent. Also, the inner rod can be quickly drawn out or retracted into the outer tube.
