发明名称 DIE, MANUFACTURING METHOD OF A LASER DISK, AND A LASER DISK
摘要 The die as provided is a die in which an upper block is placed on an upper surface of a lower block with a lower surface of the upper block in contact with the upper surface, wherein the lower block includes a manifold and a slit serving as a path for discharging paint from the manifold to the outside, constituted respectively from between the lower block and the lower surface of the upper block by forming a cavity and a space which communicates with the outside from this cavity along a columnar direction, respectively, from one end face of a columnar body with a trapezoidal shape of cross section to the other end face, a paint supply path which communicates with the manifold is formed from an outer side located between the one end face and the other end face of the lower block, a slit space dimension of the slit between front end portions in a paint discharge direction of the lower block and the upper block in a discharge port serving as an open end to the outside is smallest on the one end face side and increases toward the other end face side, and a slit length which is a dimension along the paint discharge direction of a space forming surface of the lower block constituting the slit is largest on at least one of the one end face side and the other end face side and is smallest in a position between both the end faces.
