Abstract
A mold for fabricating a light guiding plate includes an upper mold, a lower mold and a die core assembly. The upper mold defines a first cooling channel therein. The lower mold defines a cavity thereon. The die core assembly is mounted on the upper mold, and includes a base plate connected to the upper mold and a core plate detachably located at a side of the base plate facing the lower mold. The base plate defines a second cooling channel. The second cooling channel communicates with the first cooling channel respectively to cooling the mold.
Claims17
A mold for fabricating light guiding plate, comprising:
- an upper mold defining one or more first cooling channel therein;
- a lower mold defining a cavity thereon;
- and
- a die core assembly mounted to the upper mold, wherein the die core assembly comprises a base plate connected to the upper mold and a core plate detachably located at a side of the base plate facing the lower mold, and at least one gasket, the base plate is made of medium steel and defines one or more second cooling channel therein, and the second cooling channel communicates with the first cooling channel respectively to cool the mold, the core plate is made of corrosion-resisting die steel, and defines an engraving surface facing the lower mold and a plurality of microstructures on the engraving surface thereof, the at least one gasket is located between the base plate and the core plate to compensate for a decreasing thickness of the core plate due to a modification or replacement of the microstructures.
A mold for fabricating light guiding plate, comprising:
- an upper mold defining a receiving chamber thereon and a plurality of first cooling channels therein communicating with the receiving chamber;
- a lower mold defining a cavity thereon;
- a die core assembly receiving in the receiving chamber, wherein the die core assembly comprises a base plate and a core plate detachably combined together, the base plate is made of medium steel and defines a plurality of second cooling channels therein, the plurality of second cooling channels connects with the plurality of first cooling channels respectively to cool the mold, the core plate is made of corrosion-resisting die steel, and defines an engraving surface facing the lower mold and a plurality of microstructures on the engraving surface of the core plate;
- and
- at least one gasket sandwiched between the base plate and the core plate to compensate for a decreasing thickness of the core plate due to a modification or replacement of the microstructures.
