    摘要: A mold assembly for an injection-molding machine for molding a disc, including a stationary die (10, 84), a movable die (20, 88) movable relative to the stationary die, a stamper (30, 98) which is retained at least at an outer peripheral portion (31) thereof on the movable die and which has information signals recorded thereon, and an outer retainer ring (45, 102) for retaining the stamper on the movable die at the outer peripheral portion. The stationary die, stamper and outer retainer ring cooperate to define a mold cavity (C, 90), so that the disc is molded of a resin material injected into said cavity, such that the information signals are reproduced on one surface of the molded disc. The mold assembly has an annular void (S, 126) in which an outer peripheral edge of the outer peripheral portion of the stamper is accommodated without a contact with the movable die and the outer retainer ring. The mold assembly may further has a suction space (106, 136) which communicates with the stamper and/or the mold cavity, and which is connected to an external suction source, to discharge gases trapped in the mold assembly.

    摘要: A sprueless disc mold comprising: a stationary molding member (2) and a movable molding member (3); mirror plates (2d,3c) arranged to face each other between the stationary molding member and the movable molding member thereby to form a cavity for molding a disc; a stamper (7) arranged on at least one of the mirror plates for transferring recording information to the disc; a gate insert (10) arranged in a hollow portion between a gate leading to the cavity and an inlet port of a molten resin; a hot plunger (11) adapted to come into sliding contact with the gate insert (10) and heated and held; drive means (18) for moving back and forth the hot plunger to open/close the gate; an ejector mechanism (6) for protruding the molded disc; and a cooling air passage (27) for cooling down the leading end of the hot plunger (11). The hot plunger includes a shoulder portion (17b) formed at its leading end portion. The gate insert (10) includes: a leading end face (10b) forming a portion of a cavity face together with the shoulder portion (17b) of the hot plunger; an annular recess (10c) for forming the disc into a shape having one face raised to the crest of a stack rib (80); and an inner circumference (10d) extending from the inner circumferential edge of the circumferential recess toward the gate (24). The hot plunger (11) further includes at its leading end portion: an outer circumference (17d) forming the inner circumference near the gate and adapted to come into sliding contact with the inner circumference (10d) of the gate insert to close the gate; a chamfered portion (17c) formed on the corner, at which the outer circumference (17d) and the shoulder portion (17b) come into contact with each other, and having an inner slope leading from the crest of the stack rib to the face of the disc. At the protruded position of the hot plunger, the annular recess (10c) of the gate insert and the chamfered portion (17c) of the hot plunger are made to come into contact with each other to form a recess (10c) for forming the stack rib (80).

    摘要: The present invention relates to a hot press to manufacture a substrate in which a printed circuit is provid­ed. The hot press comprising at least one of vertically movable heating plates, a freely elevating movable platen which elevates the heating plates to press a plate to be treated between the heating plates, and a detecting means for detecting the movement of the uppermost heating plate when said uppermost heating plate starts to be elevated, in which the elevating speed of the movable platen is changed to lower speed by the signal generated from the detecting device. This low speed control is carried out as follows. Relief valves and direction control valves are provided at a primary side and secondary side, respectively, of a clamping cylinder into which a ram for elevating the movable platen is insertedm and due to the difference of pressures between the primary and secondary sides of the clamping cylinder, it is made possible to successively change the clamping force from zero by elevating the ram at low speed, whereby giving an optional clamping force to the ram.
