Abstract

A mold assembly device and method for assembling a semi-permanent mold assembly is disclosed, the mold assembly device includes a base die and a transfer frame, wherein the transfer frame is capable of transferring a core package to the base die and facilitates assembly of the transfer frame and the core package with the base die.

Claims (15)

1. A mold assembly device for a semi-permanent mold assembly comprising:

a base die having a cavity formed therein; and

a transfer frame adapted to support a core package having a substantially planar lower surface, wherein the transfer frame is removeably seated in the cavity of the base die and circumscribed by the base die to militate against movement of the transfer frame within the cavity of the base die, and wherein the transfer frame cooperates with a handling fixture for transporting the core package to the base die and assembling the core package with the base die, wherein an upper surface of the base die is substantially flush with an upper surface of the transfer frame.

2. The mold assembly device according to claim 1 , wherein the core package includes at least one core.

3. The mold assembly device according to claim 2 , wherein the core package includes at least one of an exhaust core, an intake core, an intake lightener core, and a water jacket core.

4. The mold assembly device according to claim 2 , wherein the at least one core is a resin bonded sand core.

5. A method of assembling a mold package, the method comprising the steps of:

providing a base die adapted for use in a mold assembly, the base die having a cavity formed therein;

providing a transfer frame having a substantially planar lower surface, wherein the transfer frame is shaped to be removeably seated in the cavity formed in the base die and circumscribed by the base die to militate against movement of the transfer frame within the cavity of the base die, and wherein the transfer frame is adapted to cooperate with a handling fixture;

assembling a core package with the transfer frame, the core package including at least one core;

transferring the transfer frame and the core package to the base die with the handling fixture; and

disposing at least a portion of the transfer frame with the core package in the cavity of the base die, wherein an upper surface of the base die is substantially flush with an upper surface of the transfer frame.

6. The method of assembling the mold package according to claim 5 , wherein the mold assembly is a semi-permanent mold assembly.

7. The method of assembling the mold package according to claim 5 , further comprising the step of providing the mold package with at least one of an exhaust core, an intake core, an intake lightener core, and a water jacket core.

8. The method of assembling the mold package according to claim 5 , further comprising the step of providing the mold package with at least one resin bonded sand core.
