Modular mold design for casting a vehicle frame and components

A modular casting mold assembly for casting an automotive component, comprising:

• a plurality of modular casting molds adapted to be modularly connected to one another, each of the plurality of modular casting molds including:
• a plurality of die portions defining a modular mold cavity corresponding to a portion of the automotive component, modular mold cavities of the plurality of modular casting molds being in fluid communication with one another when the plurality of modular casting molds are connected to define a mold cavity corresponding to the automotive component;
• and
• the plurality of die portions of each of the plurality of modular casting molds including at least one active die portion adapted to individually control the temperature of each of the plurality of modular casting molds throughout a casting process and including features for ejecting the automotive component cast within the modular casting mold.
