    摘要: A method for producing a spectacle lens 2 including a base portion 2 that is made of a resin material and includes a convex object-side face and a concave eyeball-side face, and an optical element 12 that is made of a material different from the material for forming the base portion and is embedded in the base portion, is described. The method includes: arranging an optical element in a cavity 28 of a mold including a first mold part 20 and a second mold part 24 that can be opened and closed; introducing a resin material for forming a base portion of the spectacle lens into the cavity of the mold; obtaining the spectacle lens by curing the resin material that is a resin for forming the base portion; disassembling the mold; and detaching the spectacle lens from the mold.

    摘要: A mold for in-mold foam molding of polyolefin-based resin that prevents the occurrence of burrs at the time of molding to control productivity reduction and labor cost rising caused by burr trimming. A mold is configured to mold an insert member including an embedded part to be embedded into a foaming molded body formed from a polyolefin-based resin and a protrusion part protruding from the foaming molded body integrally with the foaming molded body. The mold is provided with an accommodation concave part capable of accommodating the protrusion part and an opening/closing part capable of opening and closing a cavity-side opening in conjunction with insertion and extraction of the protrusion part into and from the accommodation concave part such that, while the protrusion part is inserted into the accommodation concave part, and the cavity-side opening is closed.

    摘要: Pocket knife, having at least one side fabricated from a molded plastic material, includes a decorative element, for example a cross, inlaid flush with an outer surface of the side. The decorative element is stamped from a sheet of steel to provide a cross and a square frame which are positioned with respect to each other by two attachments. A greater portion of each attachment is pressed down, by stamping, from a curved first plane occupied by the cross and the frame to a lower second plane under the curved first plane. This greater portion is covered over by the molded plastic material. At least one portion of lateral flanks of the decorative element is disposed at an inclined angle in order to be partially covered over with the molded plastic material. Only one single operation is required for injecting the side of the pocket knife and for inlaying the decorative element in the outer surface of the side of the pocket knife.

    摘要: A method of manufacturing a waterproof connector housing, that enables the formation of a uniform packing ring which is an integral part of the housing by engaging a hollow body of a housing with a trapezoidal engaging portion provided on a male mold, holding the housing by contacting tightly an inner wall of the hollow body with the trapezoidal engaging portion to align the center of the male mold with that of the housing, and injecting a rubber material into a packing ring forming space uniformly defined by one of both of the male and female mold through a rubber supply paths of the housing. The housing having the hollow body with tapered shoulder, a male mold having the trapezoidal engaging portion and a female mold beveled or thinned at the open edge are employed for implementing the method.

    摘要: A sheet-decorating injection molding method using a sheet clamper for fixedly holding a decorative sheet on a parting surface of a movable mold of an injection mold. At least the inner edges of the surfaces facing the movable mold of the sheet clamper are finished in smooth, convexly curved surfaces, respectively, and a groove for receiving the sheet clamper therein is formed in a fixed mold at a position corresponding to the sheet clamper in a depth sufficient to permit the movement of the sheet clamper between a position to hold the decorative sheet fixedly on the parting surface of the movable mold and a position to be separated from the decorative sheet in state where the injection mold is clamped. The sheet clamper fixedly holding the decorative sheet is moved away from the parting surface of the movable mold and separated from the decorative sheet to release the decorative sheet at a timing during a period between completion of a mold clamping process and the start of a mold opening process and is moved further away from the parting surface of the movable mold as the movable mold is moved further away from the fixed mold after the start of a mold opening process.

    摘要: A process is disclosed for manufacturing thin-walled moldings with a ground layer (4) made of thermoplastic materials and a covering layer (5) made of prefabricated flat covering materials pressed together with the ground layer by a back pressing technique in a form tool (8) having a top die (6) and a bottom die (7). The object of the process is to produce thin-walled moldings having laminated and non-laminated areas in a simple manner, with no danger of damaging sensitive covering layer materials and with non-laminated areas having a high quality surface. For that purpose, during or after back pressure lamination, while or after the two dies are closed, besides at least one molding area (2) laminated with a covering layer by a back pressing technique, at least another area (3) of the molding is produced by injection molding thermoplastic material in the part of the molding cavity (17) in which the area of the molding which is not laminated with a covering layer (5) is produced.
