Abstract: A mold for molding a green body for manufacturing a zirconium oxide dental implant includes a first molding part and a second molding part. The first and second molding parts each has a first imprinting inner surface and two none-thread inner surfaces for forming the external of the green body with two external thread sections and two none-thread sections. The mold may also include a driving mechanism, a polygonal conical slider and a screw thread forming rod. The polygonal conical slider can be driven for axially sliding into the mold cavity without rotation. The screw thread forming rod is coaxially and slidably penetrated the polygonal conical slider and driven by the driving mechanism for screwing into the mold cavity and unscrewing out of the mold cavity thereby forming the inner of the green body with an internal thread and a polygonal tapering section.

Abstract: A zirconium oxide dental implant is manufactured by injecting a zirconium oxide paste in a mold for obtaining a green body and sintering the green body to be the zirconium oxide dental implant. The green body is formed integrally with a first external thread section, a first none-thread section, a second external thread section, second none-thread section, wherein the first external thread section and the second external thread section are formed on the peripheral of the green body and divided by the first none-thread section and the second none-thread section. The mold may include at least a first molding part and a second molding part. The first molding part has a first imprinting inner surface for forming the first external thread section of the green body, and two none-thread inner surfaces for forming a half portion of the first none-thread section and the second none-thread section of the green body respectively.

Abstract: A plasticizing unit for micro injection molding machine, associated with an injection machine, is comprised of a housing and a disk-like rotor, wherein the disk-like rotor is installed inside the housing and kept rotating continuously.

Abstract: A method of forming a laminated circuit is described as follows: designing the laminated circuit in computer, recording the circuit layout of the laminated circuit into a data file subject to a predetermined format, inputting the data file into the main control unit of a laminated circuit forming apparatus for conversion into sequential control signals to drive insulative material sprayer, conductive material sprayer, and impedance material sprayer to eject respective fluid insulative materials onto a platform at different times and locations subject to the sequential control signals, forming the desired laminated circuit having an insulative body, electric circuits and passive components in it.

Abstract: A device for clamping electromagnetically molds of the injection molding machine comprises a stand on which a fixed board and a guiding mechanism are mounted. A movable board is slidably mounted on the guiding mechanism to slide back and forth in relation to the fixed board. The fixed board is provided with a male mold mounted thereon. The movable board is provided with a female mold mounted thereon. The sliding motion of the movable board toward the fixed board brings about the mold opening action, the mold closing action, and the mold locking action. The movable board and the fixed board are provided with a magnetic force generating mechanism for effecting attraction or repulsion between the movable board and the fixed board. The attraction serves to effect the mold closing action and the mold locking action. The repulsion serves to effect the mold opening action.

Abstract: A speed-up mechanism for an injection molding machine has a front fixed plate having a through hole at the center; a rear fixed plate arranged parallel with the front fixed plate, and the rear fixed plate having at least one through hole; at least two guide bars parallel to each other arranged between the front fixed plate and the rear fixed plate in an equal distance; a movable plate slidably arranged on the guide bars between the front fixed plate and the rear fixed plate, and capable of moving toward and away; a rotary power source fixed on one side of the movable plate for providing rotary power, the rotatry power source comprising a transmission device; a fixed nut mounted on the rear fixed plate; at least one ball screw having two threads in opposite directions at two ends, the front end is engaged with the transmission device for generating a radial rotation, the rear end is engage with the fixed nut and through the rear fixed plate to generate an axial movement for the ball screw during the rotation;

Abstract: An electromagnetic driving device for a mold clamping system is disclosed, which has a stationary plate fixedly mounted on a lathe bed; a mold guiding mechanism mounted parallel on the lathe bed; a movable plate slidably arranged on the mold guiding mechanism, facing the stationary plate, for generating a relative slide to the stationary plate; and a movable plate driving mechanism for driving the movable plate on the mold guiding mechanism. The electromagnetic driving device utilizes magnetic force to drive the linkage, movable plate etc. to perform open-mold movement, close-mold movement, and mold-locking movement.
