Abstract
A reusable mold for injection molding and molding method includes a reusable mold member, a mold cavity defined in the mold member, and at least one heat sink recess defined in the mold member for accommodating a heat sink material therein for rapidly removing heat from the mold cavity when the mold member is used to injection mold a molded part. The reusable mold injection molds a molded part and rapidly removes heat from the mold cavity via a heat sink material accommodated in the at least one heat sink recess.
Claims20
A reusable mold for injection molding, comprising:
- a reusable mold member;
- a mold cavity defined in the mold member;
- and
- at least one heat sink recess defined in the mold member for accommodating a heat sink material therein for rapidly removing heat from the mold cavity when the mold member is used to injection mold a molded part.
A molding method for injection molding with a reusable mold, comprising:
- providing a reusable mold member having a mold cavity defined therein and at least one heat sink recess defined therein accommodating a heat sink material for rapidly removing heat from the mold cavity;
- injection molding a molded part with the reusable mold member;
- and
- rapidly removing heat from the mold cavity of the mold member via the heat sink material accommodated in the at least one heat sink recess.
A molding method for injection molding, comprising:
- adding a fusible metal alloy to a reusable mold member;
- injection molding a molded part with the reusable mold member;
- and
- rapidly cooling the molded part in the reusable mold member by transferring heat from the molded part to the fusible metal alloy sufficient to phase change the fusible metal alloy from a solid state to a liquid state.
