A liquid cooled wax mold includes a generally rectangular two-part heat transfer member formed by separable metal plates. One of the plates includes elongated parallel vertically-extending heat transfer bars or fins defining parallel liquid coolant flow passages. The coolant flow passages interconnect spaced apart liquid coolant distribution and collection passages which are, respectively, connected to coolant inlet and discharge passages. A dam is interposed between the coolant collection passage and the discharge passage to provide for purging air or coolant vapor from the coolant flow circuit. Elongated circular cross section seal strips are disposed in grooves formed in one of the plate members to provide a fluid-tight assembly of the heat transfer member. Mold endwall and bottomwall members are secured to the heat transfer member by socket head machine screw fasteners. Locating shoes on the endwall members align the mold with an adjacent mold in a molding apparatus wherein the molds are stacked side-by-side to form open-top mold cavities. Opposed support handles are mounted on the mold endwall members, respectively.

[ What is claimed is:] [1.] A liquid-cooled wax mold comprising:a heat transfer member defining a cavity sidewall of said mold and a cavity sidewall of an adjacent mold;opposed endwall members and a bottomwall member connected to said heat transfer member and defining at least one mold cavity; andsaid heat transfer member comprising liquid coolant passages formed therein including a coolant inlet passage and a coolant discharge passage, a plurality of spaced apart, generally parallel heat transfer bars defining, in part, spaced apart generally parallel coolant flow passages, said flow passages extending generally vertically when said mold is disposed for receiving molten wax in said cavity, a generally horizontally extending coolant distribution passage disposed below said flow passages for conducting coolant from said inlet passage to each of said flow passages and a coolant collection passage disposed above said flow passages for receiving coolant from each of said flow passages and for conducting coolant to said discharge passage, said passages being configured to distribute flow of liquid coolant through said heat transfer member to flow generally vertically upwardly from said coolant distribution passage directly to said coolant collection passage to provide substantially uniform cooling of molten wax in said cavity.
