Metal Molding Machines

Metal molding machine includes a fixed mold and a movable mold, a fixed platen holding the fixed mold, an end frame coupled to the fixedplMetal Molding Machinesaten by tie rods such that the end frame is fixedly mounted on a bed, a movable platen guided by the tie rods, the movable mold being held by the movable platen, and a rolling support mechanism supporting the movable platen. The rolling support mechanism includes a swingable arm, a wheel disposed on a portion of the swingable arm that is closer to the fixed platen and held in rolling contact with the bed, and a spring disposed on a portion of the swingable arm that is closer to the end frame. The spring is interposed between the swingable arm and a portion of the movable platen, for applying a resilient force in a direction so as to lower the wheel.

A metal molding machine comprising a fixed mold and a movable mold, which can be held against each other to jointly define a mold cavity;a fixed platen fixedly mounted on a bed, said fixed mold being held by said fixed platen; an end frame coupled to said fixed platen by at least one tie rod, said end frame being fixedly mounted on said bed; a movable platen movable between said fixed platen and said end frame while being guided by said tie rod, said movable mold being held by said movable platen; and a rolling support mechanism supporting said movable platen on said bed,wherein said rolling support mechanism further comprises a swingable arm swingable about a support shaft mounted on said movable platen; a wheel disposed on a portion of said swingable arm that is closer to said fixed platen, and held in rolling contact with said bed; and a resilient member disposed on a portion of said swingable arm that is closer to said end frame, said resilient member being interposed between said swingable arm and a portion of said movable platen, for applying a resilient force in a direction so as to lower said wheel against said bed.
