Abstract:
1. An apparatus for use in injection molding, comprising: a heatsink with a main body with a base, and with a front side and a rear side and a front-rear axis and lateral axes, and with at least one load-bearing path that extends generally parallel to the front-rear axis of the heatsink so as to intersect a molding surface on the front side of the heatsink and that comprises at least a frontward segment and a rearward segment; wherein at least a portion of at least one non-load-bearing, dynamic heat-transfer zone of the rear side of the heatsink is laterally offset from the rearward segment of the load-bearing path; and wherein the dynamic heat-transfer zone comprises dynamic heat-transfer fins that extend generally rearward from the base of a main body of the heatsink and that collectively comprise a dynamic heat-transfer surface area, and wherein the main body of the heatsink comprises a total thermal volume, and wherein the ratio of the dynamic heat-transfer surface area to the total thermal volume is at least 1 cm
