摘要： A molded plastic part prepared by injecting a resin in a cavity of a die so that a pressure is generated in the resin in the cavity and at least one transfer wall surface of the cavity is transferred to the resin. The plastic part has at least one transferred surface; at least one imperfectly transferred concave portion on a first surface thereof other than the transferred surface; and at least one imperfectly transferred convex portion on the first surface or a second surface thereof other than the transferred surface. The ratio (a)/(b) of the thickness (a) of the plastic part in a direction perpendicular to the transferred surface to the thickness (b) of the plastic part in a direction parallel to the transferred surface is less than 1.

摘要： There is provided an injection mold for molding an optical component including an optical surface, a non-optical surface separated from the optical surface, and a rib provided to an edge portion of the optical surface, and longer in a direction parallel to the optical surface than in a direction perpendicular to the optical surface. The mold includes a transfer piece including a transfer surface that molds the optical surface and a movable cavity piece including a non-transfer surface that molds at least a portion of the non-optical surface. The transfer surface and the non-transfer surface define a cavity to be filled with resin. The movable cavity piece is moved away from the resin during a process of cooling the resin. At least a portion of the non-transfer surface is located closer to the rib than a boundary between the transfer surface and the rib.
摘要翻译：提供了一种用于模制光学部件的注射模具，该注射模具包括光学表面，与光学表面分离的非光学表面，以及设置在光学表面的边缘部分上的肋条，并且在平行于光学表面的方向上较长而不是垂直于光学表面的方向。该模具包括一个转印件，该转印件包括模制该光学表面的转印表面和一个包括非转印表面的可移动的空腔件，该非转印表面模制非光学表面的至少一部分。转印表面和非转印表面限定了用树脂填充的空腔。在冷却树脂的过程中，可移动的空腔件离开树脂。非转移表面的至少一部分位于比转印表面和肋之间的边界更靠近肋的位置。
