Abstract:
In combination with vibratory concrete product molding machine elements including a frame with wall surface defining generally horizontal mold support surfaces for opposite ends of a mold, a mold having a vertically extending mold cavity including an upper opening portion permitting the supply of a concrete mix to the mold and a lower vertically open portion, a pallet support mounted for lifting movement to dispose a pallet against the lower portion of the mold to close said lower open portion thereof, support attachment structure extending from the mold in a y axis direction to rest on said mold support surfaces prior to being moved upwardly by said pallet support to provide a clearance for vibration of said mold, and a vibrating mechanism for vibrating said mold in a vertical path having lateral x and y axis vibration components, the improvement comprising:a. a vertical guidance pin receiving member carried by said support attachment structure; b. a pin carrier assembly mounted on said frame and carrying a vertically disposed guidance pin mounted for vertical reciprocating movement from a position in which its upper end is disposed inoperatively vertically spaced from said pin receiving member and an operative position in which said pin is received by said receiving member and guides the mold in its vibratory travel; c. a vibration limiter disposed laterally relative to said pin for limiting at least one of said lateral vibration components; and d. motor operated mechanism mounted on said frame having a connecting assembly coupled to said pin for moving said pin vertically.
