A method of providing a male mold half for molding a toric contact lens at a predetermined target rotational orientation is disclosed. The method comprises the steps of: providing the male mold half at a predetermined rotational orientation, picking the male mold half up with a gripper having a central axis, rotating the gripper with the male mold half about the central axis of the gripper by a predetermined rotational angle (?) towards the predetermined target rotational orientation, and releasing the rotated male mold half from the gripper. Prior to picking the male mold half up, the method comprises centering the grippe and the male mold half relative to each other such that the central axis of the gripper and a central axis of the male mold half coincide.

A display system includes: an imaging unit that images a mold from below; and a display unit that displays an image taken by the imaging unit together with a carry-in range of the mold in order to transport the mold in place between the stationary platen and the moving platen.

Provided is a resin-molding device 10 including: a first platen 11 and a second platen 12; a first molding die 161 to be attached to the first platen; a second molding die 162 to be attached to the second platen and arranged so as to face the first molding die; a die-clamping mechanism 133 for clamping the first and second molding dies together by decreasing the distance between the first and second platens, and for separating the first and molding dies from each other by increasing the distance between the first and second platens; and a flatness adjuster 14 including an adjustment member 141 for adjusting the parallelism between the die surface of the first molding die and that of the second molding die, or the flatness of a resin-molded product to be molded with the first and second molding dies.

There is provided a mold assembly for molding a car door handle, the assembly comprising: a cavity mold as an upper mold, wherein the cavity mold has an elongate cavity defined in an upper body; a core mold as a lower mold, wherein the core mold has an elongate protrusion from a lower body; and first and second inserts received in the molds, wherein each of the first and second inserts has a first curved portion at a first edge of each of the first and second inserts, wherein the cavity mold has a second curved portion at a second edge of each of the first and second cavity mold-side insert-receiving recesses, the second edge abutting the first edge, wherein a parting line for the car door handle is defined as a contact line between the first and second curved portions, wherein the second curved portion extends upward in an upwardly convex shape, while the first curved portion extends downwardly in a downwardly convex shape.

A cast mould for manufacturing a contact lens or an intraocular lens, wherein the cast mould is provided with a central part and a bearing ring and a flexible connection between the central part and the bearing ring. Further, an injection mould is provided for manufacturing such a cast mould and a method for manufacturing such a cast mould. The injection mould is provided with a mould cavity with a plunger biased by spring means towards the mould cavity which serves for compensating shrinkage which occurs during the curing of the plastic injected into the injection mould. Also described is a method for manufacturing a contact lens or intraocular lens with the aid of the cast mould, as well as a contact lens or intraocular lens obtained with this method.

A molding device and a molding method are provided. The molding device includes an upper molding assembly and a lower molding assembly. The upper molding assembly includes an upper molding plate and a plurality of positioning columns disposed thereon. The mold core and a plurality of matching columns surrounding the mold core are disposed at the same side of the upper molding plate. The lower molding assembly includes a lower molding plate and at least one formation mold, wherein the lower molding plate has at least one accommodating groove, a plurality of matching grooves and a plurality of positioning holes surrounding the accommodating groove. The formation mold is disposed in the accommodating groove, and the formation mold has a formation cavity corresponding to the mold core. Each positioning column is disposed respectively into each positioning hole, and each matching column is disposed respectively into each matching groove.

A fiber reinforced composite member molding apparatus comprises a pair of mold parts which are brought nearer to and away from each other, and in a mold clamping state, clamp laminated sheets of prepreg formed of woven fiber fabric impregnated with resin, and heat sources for heating the resin in the prepreg through the pair of mold parts, wherein the two mold parts each comprise a base mold and a design mold which is detachably attached to the base mold and brought into contact with the prepreg, wherein the design molds of the mold parts are made of a metal lower in thermal expansion rate than the base molds. The mold parts having such split structure can reduce the burden on operators handling replacement of the mold parts, and also can suppress, during heating for molding, the influence of thermal expansion of the mold parts upon a to-be-molded fiber reinforced composite member.

A light-guide optical element (LOE) and methods of manufacture are disclosed. The LOE includes a transparent substrate having a first refractive index, the substrate having a pair of parallel external surfaces along a length thereof, and a plurality of mutually parallel at least partially reflective internal surfaces, the mutually parallel internal surfaces being angled obliquely relative to the pair of external surfaces; and a transparent polymer resin encapsulating at least a part of the substrate to form an encapsulated structure, the polymer resin having a second refractive index that is matched to the first refractive index; wherein the encapsulated structure comprises a pair of parallel external surfaces of optical quality formed from the resin.

A platen for use with an injection molding machine includes a body having an opening for receiving a ring protruding from a mold for aligning the body and the mold. The opening includes a tapered recess having a surface extending radially outward from the opening. The tapered recess defines opposed edges along an outer surface of the body, the opposed edges converging in a radially outward direction away from the opening.
