Apparatus for effecting simultaneous free-fall jolting and squeezing of foundry molds during production thereof

Apparatus for the production of foundry molds adapted to simultaneously effect both free-fall jolting and squeezing of said molds during the production thereof comprising:

• a mold forming assembly at least including a pattern device and a molding box capable of having material for forming said mold contained therein;
• jolter-squeezing means including a press, a jolter table and at least a pair of columns, said press and said columns being structured to form a gantry, said columns rigidly interconnecting said jolter table and said press and extending continuously therebetween;
• conveyer means located in operative proximity relative to said jolter-squeezing means for reversibly moving said mold forming assembly between one position, at which said molding box is placed on the pattern device and molding material is filled thereinto, and another position on said jolter table within said gantry for simultaneous free-fall jolting and squeezing of said filled mold forming assembly;
• means extending between said one position and said another position for supporting and guiding said mold forming assembly while said assembly is being conveyed by said conveyor means between said one position and said another position;
• means operatively associated with said guiding and supporting means for raising and lowering said guiding and supporting means;
• and
• coupling means operably engageable between said mold forming assembly and said conveyer means for enabling coupling and uncoupling of said mold forming assembly and said conveyer means to effect movement of said mold forming assembly to said one and said another position during production of said foundry mold, with said mold forming assembly being uncoupled from said conveyer means after said mold forming assembly has been placed in said another position.
