Abstract

The present invention provides a method for sectionally controlling a cooling efficiency of a mold. The method comprises steps of: (a) configuring at least a cooling passage including a first section having a first heat-dissipating inner surface area and a second section having a second heat-dissipating inner surface area in the mold; and (b) adjusting the first and the second heat-dissipating inner surface areas unequally by using a heat-dissipating element.

Description

FIELD OF THE INVENTION

[0001] The present invention claims the benefits of priority from the Taiwanese Patent Application No. 100142109, filed on Nov. 17, 2011, the contents of the specification of which are hereby incorporated herein by reference. The present invention relates to a mold and a method for adjusting cooling efficiency, particularly a hot-stamping mold and a method of sectionally adjusting the cooling efficiency of the hot-stamping mold.BACKGROUND OF THE INVENTION

[0002] The production method for a cooling water passage according to the prior art is to drill a mold to form tunnels therein for allowing cooling water to flow in the tunnels. Due to the physical limitations of the drilling machine, each of the tunnels formed in the mold is in one direction, i.e. strait lines. However, the contours of a mold are usually curvature. Thus, the distance between the cooling water passages made by drilling inside the mold and the outer surface of the mold cannot be constant, which re...
