Disclosed is an inorganic composition for transferring a fine unevenness by which a fine unevenness made of an inorganic material capable of controlling a refractive index can be fabricated through a suitable transfer process. The composition according to the present invention contains a silicone compound and at least two types of metal alkoxides, wherein the metal alkoxides include a metal alkoxide having a metal species M1 (where M1 denotes at least one metal element selected from a group consisting of Ti, Zr, Zn, Sn, B, In, and Al) and a metal alkoxide having a metal species Si. In addition, a ratio between a molarity CM1 of the metal alkoxide having the metal species M1 and a molarity CSi of the metal alkoxide having the metal species Si in the inorganic composition for transferring a fine unevenness satisfies a condition of 0.2≤CM1/CSi≤24.

An injection molding device comprises a mold-clamping device that operates in both of a mold-closing state in which a mold is closed under predetermined pressure and a micro mold-open state in which the mold is held in a state in which the mold is open from the mold-closing state by a predetermined amount, an injection device that molds a molded product by injecting a molding material into the mold set to the mold-closing state or the micro mold-open state and a controller that changes a stop position of the mold in the micro mold-open state in accordance with a change of a mold-closing position when the mold-closing position of the mold in the mold-closing state is changed.

Used in a method of this invention is a die clamping unit, which comprises a tie bar movably attached to a stationary platen, a halfnut positioning servomotor which advances and retreats to the tie bar, a halfnut which is provided on a movable platen and fixes the movable platen and the tie bar together by engaging the tie bar, an engaging mechanism which engages the halfnut with the tie bar, a hydraulic die clamping cylinder which presses the stationary platen and the movable platen, and a control device which controls the halfnut positioning servomotor and the hydraulic cylinder. The control device drives the halfnut positioning servomotor to remove a clearance between the halfnut and an engaging groove of the tie bar before a die clamping process carried out by the hydraulic cylinder.

A stationary platen unit and a movable platen unit each include a platen body, a load transmission portion, a die fixing plate, and a backup member. The backup member is located between the platen body and the die fixing plate. The backup member is movable between a first position in which it is in contact with both the die fixing plate and the platen body and a second position in which it is separate from the die fixing plate and/or the platen body. When a large die set is attached to the die fixing plate, the backup member is situated in the first position. When a small die set is attached to the die fixing plate, the backup member is moved to the second position.
摘要:
A method of molding a minute shape, in which at least one of a pair of dies is provided with an uneven section of a minute shape on a molding surface thereof, clamping of the pair of dies is stopped immediately before the dies are completely clamped, a resin is injected into a cavity, and thereafter the dies are completely clamped to thereby transcribe the shape of the uneven section onto the resin includes preparing a plurality of transcription dies each provided with the uneven section on a molding surface thereof, heating one of the transcription dies which is not used to mold a product by a heating unit, and exchanging the transcription dies with each other, at a point in time at which molding is completed, to thereby mold the product continuously.

A die drive unit has a cylinder mechanism which hydraulically drives a piston member and an additional drive mechanism which drives the piston member by means of a drive source other than a hydraulic one. A first oil chamber is formed on one side of the piston member. A second oil chamber and a third oil chamber are formed on the other side of the piston member. The first oil chamber and the second oil chamber are connected to each other by an oil passage. The piston pressure receiving area of the first oil chamber is equal to the sum of those of the second and third oil chambers.

A tie-bar less clamping apparatus is intended for use in combination with an injection molding machine. A stationary platen (24) is fixed to a first support section (20B) of a support frame (20), and linear motors (30) are incorporated into the second support section (20C) of the support frame (20). One end of an armature (34) included in each linear motor (30) and having the shape of a rod is connected to a movable platen (28).
摘要:
An injection apparatus of an injection molding machine, for easy control of the charging motor and the injection motor and highly precise control of the back pressure of a screw thereby enabling performance of the proper charging operation, has an injection motor with a rotor adapted to act as a ball screw nut and which is secured to an injection carriage having mounted thereon a heating barrel of the injection apparatus. The injection motor has a shaft forming a ball screw in one end portion of the shaft connected to a screw of the injection molding machine. The ball screw is screwed into the rotor of the injection motor. The other end of the shaft forms a spline portion, and is connected to a charging motor that has a hollow drive shaft whose inside-diameter portion is spline-fitted onto the spline portion of the shaft.
