摘要： A disc-molding mold includes a first support plate disposed at the stationary side of the mold; a first mirror-surface disc attached to the first support plate; a first guide ring disposed radially outside the first mirror-surface disc and attached to the first support plate; a second support plate disposed at the movable side of the mold; a second mirror-surface disc attached to the second support plate; a second guide ring disposed radially outside the second mirror-surface disc and attached to the second support plate; a guide post attached to either the first or second guide ring and projecting toward the other guide ring; and a guide bushing attached to the other guide ring and adapted to guide the guide post. The first and second guide rings each have a temperature control medium passage formed therein in order to allow passage of a temperature control medium. Thus, the thermal expansion of the first guide ring is made equal to that of the second guide ring.

摘要： An injection molding die for simultaneously molding a plurality of optical disc base boards. The die has a stationary die assembly portion that includes a first base plate having a first center axis, and a plurality of first cavities each having a respective center axis. The first cavities are arranged in an equally spaced relationship along a circumference of a circle coaxial with the first center axis. The die also has a movable die assembly portion that includes a second base plate having a second center axis, and a plurality of second cavities each having a respective center axis. Each second cavity positionally corresponds to a respective first cavity. The first center axis is aligned with the second center axis using a guide rod fixedly secured to the first base plate and that extends along the first center axis, and by using a guide member that extends along the second center axis to be positionally coincident with the first center axis. The guide member has a guide hole formed therein for receiving the guide rod. Each respective first cavity center axis is additionally aligned with each corresponding respective second cavity center axis.

摘要： An object is to provide a disc-molding mold which can increase the degree of transfer of a pattern of a stamper to thereby improve quality of molded products, as well as a molded product and a molding machine. In the vicinity of the outer peripheral edges of first and second disc-shaped members, the cooling capacity of the medium flow passage of the stamper-side disc-shaped member is made lower than the cooling capacity of the medium flow passage of the non-stamper-side disc-shaped member. On the stamper side, the quantity of heat radiated from the outer peripheral edge of the stamper-side disc-shaped member to the outside of the disc-molding mold can be reduced, whereby over-cooling of the stamper-side disc-shaped member can be prevented. As a result, a local deterioration in the degree of transfer, which would otherwise occur in the vicinity of the outer peripheral edge of the cavity space (C), can be prevented, and thus the degree of transfer of the fine pattern can be improved over the entire cavity space (C) As a result, quality of molded products can be improved.

摘要： An object is to provide a mold apparatus which can prevent inclination of a machining member to thereby improve quality of molded products. The mold apparatus includes a first mold unit; a second mold unit; a sprue bush (24) disposed in one of the first and second mold units and having a sprue (26) for charging a molding material into a cavity space (C); a machining member disposed in the other of the first and second mold units in such a manner that the machining member can be advanced and retracted, the machining member performing a predetermined machining for a prototype of a molded product when the machining member is advanced; and a bush (47) disposed radially outward of the machining member to surround the machining member and having a flow passage (55) which is formed in a front end portion thereof and through which a temperature control medium flows. Since the flow passage (55) through which a temperature control medium flows is formed in a front end portion of the bush (47), a temperature control flow passage is not required to be formed in the front end portion of the machining member. Accordingly, since a support member can be disposed at a location offset toward the front end of the bush (27), generation of inclination of the machining member can be prevented.

摘要： A disc molding die includes a stationary-side mirror block disposed on a stationary die, a movable-side mirror block disposed on a movable die and facing the stationary-side mirror block so as to define a cavity in combination with the stationary-side mirror block, and a cavity ring disposed on the radially outer side of one of the stationary-side mirror block and the movable-side mirror block so as to define the outer circumferential edge of each disc substrate. The portion of the cavity ring facing the cavity is roughened. When resin is charged into a cavity, very small spaces are formed between the resin and the inner circumferential surface of the cavity ring, due to the roughened portion of the cavity ring facing the cavity. Therefore, the release resistance during die opening or releasing can be decreased. As a result, it is possible to solve the conventional problem in which the disc substrate deforms, causing the angle of warp to vary at circumferential positions and increasing the amount of surface deflection. Therefore, the quality of the disc substrate can be increased. Further, since the release operation can be performed before a molded disc substrate sufficiently shrinks, tact time can be shortened.
摘要翻译：圆盘成形模具包括设置在固定模具上的固定侧反射镜块，设置在可动模具上并面向静止侧反光镜块的可动侧反射镜块，以便与固定侧镜组合形成空腔并且设置在所述固定侧镜块和所述可动侧镜块之一的径向外侧上的腔环，以限定每个盘基片的外周边缘。面向空腔的空腔环的部分被粗糙化。当树脂被填充到空腔中时，由于空腔环的粗糙部分面向空腔，所以树脂和空腔环的内圆周表面之间形成非常小的空间。因此，可以降低开模或释放期间的耐剥离性。结果，可以解决盘基板变形的常规问题，导致翘曲角度在周向位置变化并增加表面偏转量。因此，可以提高盘基片的质量。此外，由于可以在模制盘基板充分收缩之前进行释放操作，所以可以缩短节拍时间。
