PROBLEM TO BE SOLVED: To provide a mold for molding a disk substrate capable of setting the coaxial degree of two mold cores capable of molding a plurality of disk substrates with high accuracy. SOLUTION: A mold 23 has two mold cores 231A, 232 fixed to the respective opposed surfaces of two platens 21, 22 relatively movable in opposed relationship and brought to a mutual contact state to form cavities 233 for molding a plurality of disk substrates. One mold core is divided at every cavities. When the respective split mold cores and the other mold core are mated with each other coaxially, they are brought to a close contact state and the split mold cores are temporarily fixed to one platen and the other mold core is fixed to the other platen. The split mold cores and the other mold core are raised to predetermined temp. to be thermally expanded and, after the split mold cores are slid along one platen, the split mold cores and the other mold core are finally fixed.
Abstract:
PURPOSE: To mold a thin-walled disk generating no deformation by providing a plurality of fine holes to the first wall surface attaching the disk original plate becoming the mold of one surface of a thin-walled disc of a circumferential wall surface forming a space and applying negative pressure to the disk original plate through the fine holes. CONSTITUTION: In a mold 40, the center hole of a stamper 11 is set so as to be fitted to the first core 42 of a fixed mold half body 41 and a negative pressure source applying negative pressure to the respective fine holes 42B of a fixed mirror 42 is driven to suck and fix the stamper 11 to the mirror surface 42A of the fixed mirror 42. In this case, since the stamper 11 can be received only by the mirror surface 42A of the fixed mirror 42 in the mold 40, the deformation caused by the thermal expansion or contraction of a disk original plate can be prevented and a mold capable of forming a thin-walled disk free from deformation as a molded product and having a wide signal recording region can be realized.
Abstract:
PURPOSE:To simplify the structure of the molding die by forming the structure of the mold for molding the tape cassette half in such a manner that the bearings of a prism and lid can be molded by a pair of cores sliding toward the axial direction of the lid and the outer side of a housing. CONSTITUTION:The bearing parts of the prism and the lid are molded by the sliding cores 43, 44 which can be slide and moved toward the outer side. The projecting parts 43a, 44b of the sliding cores 43, 44 exist in the positions corresponding to the body part of the prism and prohibit the inflow of a primary injection resin at the time of primary injection for molding the upper half body. The structure of the mold for molding the upper half of the tape cassette is, therefore, simplified.

PROBLEM TO BE SOLVED: To provide a multicolor molding method for manufacturing molded parts with excellent durability and high degree of freedom of shapes, a multicolor molding apparatus and multicolor molded parts manufactured by the same.SOLUTION: A base material film 14 with an in-mold layer 13 formed thereon is disposed between separated first and second cavity members 10a and 10b. This configuration can suppress the deformation of the base material film 14 mainly within a concave part 3, when a primary molding resin 15 is injected, to lessen the deformation amount of the base material film 14. Thus, a set range of the shape of a primary cavity 8 formed of a through-hole 2 and the concave part 3 can be increased to mold a primary molding layer 15' having the high degree of freedom of the shape. The in-mold layer 13 is transferred onto a bonding face 17 of the primary molding layer 15', so that a second molding layer 18' can be easily molded not to expose the in-mold layer 13, to thereby mold multicolored molded parts with excellent durability.
Abstract:
PROBLEM TO BE SOLVED: To provide a configuration laminated with two or more layers of information recording layers having information rugged surfaces, formed with a light transmission layer 3 by a transparent thin film body on a photoirradiation side and formed with a rugged information layer on the light transmission layer itself and to manufacture the light transmission layer, i.e. the transparent thin film body having high optical property by injection molding. SOLUTION: The information recording medium disk 1 is constituted by laminating a disk substrate 2 formed with the rugged information surface constituting the information recording layer 11 on at least one major face and laminating the light transmission layer 3 consisting of the thin film body with a clamping part formed with the rugged information surface through at least a transparent intermediate layer 5 on the major face formed with the information recording layer 11 of the disk substrate 2 and forming a central hole 4. A thick-walled projecting part 3C is formed in the clamping part 31 in the central part of the light transmission layer 3 constituted by the thin film body with the clamping part, by which the injection molding of the light transmission layer 3 having mechanical strength, ease of handling and excellent optical characteristics at a good yield is made possible.
