Abstract
A mold (200) for manufacturing a heat dissipation apparatus (10) includes a movable mold (20) and a fixed mold (30) covering the movable mold. The heat dissipation apparatus includes a plurality of fins (12). One of the movable mold and the fixed mold includes an insert group (50). The insert group includes a plurality of separated inserts (51) stacked together. A plurality of compartments (513) are formed between adjacent inserts of the insert group for forming the fins of the heat dissipation apparatus when molten metal is injected into the mold.
Claims16
A mold for manufacturing at least a heat dissipation apparatus with a plurality of fins, comprising:
- a movable mold;
- and
- a fixed mold covering the movable mold;
- wherein one of the movable mold and the fixed mold comprises an insert group which comprises a plurality of separably stacked inserts, wherein a plurality of compartments are defined between adjacent inserts of the insert group for forming the fins of the at least a heat dissipation apparatus.
A method for manufacturing at least a heat dissipation apparatus comprising:
- providing a mold, the mold comprising a movable mold and a fixed mold, one of the movable mold and the fixed mold defining a chamber for receiving a mold core therein, the mold core defining an opening for receiving an insert group therein, the insert group comprising a plurality of separably stacked inserts and defining a plurality of compartments formed between adjacent inserts;
- bringing the movable mold and the fixed mold together;
- injecting molten metal into the mold;
- cooling the molten metal to obtain a rough cast;
- separating the movable mold from the fixed mold;
- pushing the rough cast out of the mold;
- and
- dressing the rough cast to obtain the at least a heat dissipation apparatus, wherein the metal in the compartments forms a plurality of fins for the at least a heat dissipation apparatus.
