摘要： A machine for making molds and molding cores (126) includes a pair of mold boxes (42a, 42b) removably mounted on a frame (60) for rotation between an upright, molding position in which molding material is introduced into the molding cavity of the molding boxes (42a, 42b) by a carrier (26) and an inverted discharge position in which the mold (126) is removed from the boxes by a mold receiving assembly (76). A pressure head assembly (46) both compresses molding material within the molding cavity and introduces a catalyst gas into the cavity for curing the molding material. A system for removing the spent gas from the molding cavity includes a pair of gas receiving chambers (122a, 122b) integral with the frame (60) which receives gas through the bottom of the mold boxes (42a, 42b) and an exhaust assembly (68, 70) which is selectively coupled with exhaust ports (124a, 124b) in the chambers (122a, 122b ). A mold transfer carriage (84) transfer molds (126) discharged from the mold boxes (42a, 42b) to either of two lateral positions and can be employed to automatically change mold boxes (42a, 42b) which are mounted on the frame (60) by quick release connections (62, 64, 134).

摘要： Apparatus (20) for bonding a pair of molds shells (28a, 28b) into a mold includes a first workstation (24) for applying adhesive to one of the shells (28b), and a second workstation (26) having a press (104, 106, 108) for pressing together the shells (28a, 28b) after adhesive has been applied thereto. A base (42) includes a pair of spaced apart base portions (42a, 42b) which are pivotally mounted so as to alternately rotate between the first and second workstations (24, 26). The first workstation (24) includes an adhesive applicator (58) carried on a carriage (88) which is slidably mounted on guiderails (94) so as to shift to a standby position providing access to a mold shell (28b) located on a base portion (42a) so as to allow the shells to be loaded and unloaded at the first workstation (24). A motor driven drip tray (80) is provided on the adhesive applicator (58) to prevent unintended dripping of adhesive onto mold shells or fixtures. Sensors (122, 124, 125, 130, 132, 137, 142) provide signals to a programmable controller (110) which operates electrical and fluid driven motor components of the apparatus.

摘要： A foundry machine for forming molds or cores from a molding material such as sand provides completely automated loading and unloading of tooling elements (24). The tooling elements (24) comprising a sand magazine (36), blow plate (34), combined gassing manifold and top ejector unit (32), upper mold box (30), lower mold box (28) and bottom stool (26) are automatically transferred, in stacked, separable relationship, by tracks (40) to a vertically displaceable, work table. Vertical displacement of the work table (42) sequentially elevates the tooling elements (24) to positions within a mainframe (10) where automatically operated clamping means secure the appropriate tooling elements (24) in respective operating positions. The gassing manifols (32) includes an ejector pin assembly (274, 280) mounted therewithin.
