Definitions

  • the present 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.
  • a mold for molding an object comprises a cooling passage and a heat-dissipating element.
  • the cooling passage device has a heat-dissipating inner surface area.
  • the heat-dissipating element is disposed in the cooling passage device for causing the heat-dissipating inner surface area to be inhomogeneous.
  • FIGS. 3A to 3E illustrates a method for manufacturing a mold having multiple cooling passages according to the present invention
  • heat-dissipating elements 12 such as fins, configured inside of the cooling passage 11 at the cross section A-A while no heat-dissipating element 12 in the cooling passage 11 at the cross section B-B.
  • the heat-dissipating inner surface area (not shown) of the section near the cross section A-A is larger than that of the section near the cross section B-B, and therefore the cooling efficiencies of the section near A-A is higher than that of the section near B-B.
  • the coolants available for the embodiment includes water, vapor, liquid helium, oil, air, and any other material applicable for the use of cooling inside a mold.
  • the embodiments set forth above according to the present invention can be realized with many manufacturing processes known to the art.
  • the present invention simply provides an embodiment of a method for manufacturing a mold with heat-dissipating elements disposed in at least one cooling passage of the mold.
  • the method comprises the following steps: Firstly, providing a mold base 30 which has a shape the same with that of the embodiment shown in FIGS. 1A to 1C ; Secondly, configuring one or plural cooling passages 31 around the working surface of the mold base 30 , wherein each of the cooling passage 31 has a heat-dissipating inner surface area, as illustrated in FIG. 3B ; Thirdly, providing a lower mold cover 32 .
  • the heat-dissipating elements 33 may be attached on the inner wall of the cooling passage 31 by wielding or sticking, or be fastened with fasteners.
  • the heat-dissipating elements 33 are disposed on locations of the lower mold cover 32 corresponding to the required positions inside the cooling passages 31 when the lower mold cover 32 covers the lower mold base 31 (referring to FIG. 3E ).
  • the at least two portions of the mold 10 , 30 , 40 having different heat-dissipating inner surface area can be considered as a first and a second sections which may be located in right-and-left, front-and-back, upstream-and-downstream, or any different two locations in the mold 10 , 30 , 40 .
  • a method for sectionally controlling a cooling efficiency of a mold comprising steps of:
  • cooling passage includes a first and a second cooling sub-passages having different heat-dissipating inner surface areas.
  • a lower mold base having a top surface and including a cooling channel disposed on the top surface
