摘要： The injection tube for injecting and gassing of foundry sand in cavities in a core box has a first passage for passing sand and a second passage for passing hardening fluid. Sand may be injected simultaneously to the introduction of hardening fluid into the cavities. Alternatively, sand may be injected prior to introduction of hardening fluid into the cavities.

摘要： A handling apparatus for a core molding machine is capable of moving a core box portion between a molding position and an eject position using only a single actuator. A carriage carries a platen that supports a core box portion wherein the platen is rotatable about a pivot axis relative to the carriage. The platen carries a roller that rolls on a cam surface adjacent the carriage. As the carriage is retracted away from a molding position, the roller rolls over the cam surface and permits the platen to pivot relative to the carriage downwardly toward the eject position.

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 cope for a core box has a passage for passing sand into a core box cavity and a bore for passing catalyst into the core box cavity to harden a sand core formed therein. The bore may extend from an exterior surface of the cope to the cope passage. The cope may have structure for forming a seal with a sand injection tube following sand injection, such as a blow-up seal or an O-ring. A method of producing cores in a core box includes the step of providing a cope, a drag, and a cavity formed therebetween, the cope having a passage for receiving an injection tube and a bore for passing catalyst. Further steps include using the injection tube to inject sand through the cope passage into the cavity and passing catalyst through the bore in the cope into the cavity. A seal may be formed between the cope and the injection tube after sand injection.
