摘要： A mold handling system for transferring molds from multiple feed lines to a single main conveyor. The present invention provides an improved and simplified system for transferring molds from several mold making machines to a single conveyor leading to a pouring station. Through the use of a transfer conveyor with cantilevered arms which intersect with the feed lines and the main line, molds can be transferred from the transfer conveyor to the main line by raising and lowering the cantilevered arms. A simplified mechanism for raising and lowering the transfer conveyor is provided in the form of an air actuated bellows apparatus. In order to provide lateral support to the transfer conveyor, brackets flank the bellows that are provided with a predetermined amount of lateral play to provide both the lateral support to the transfer conveyor, as well as enable the transfer conveyor to be raised and lowered.

摘要： The cope flask and drag platen of a matchplate molding machine are supported for up and down movement on vertical guide rails by sliding bearings or slippers located adjacent to corners of the flask and the platen. Each slipper includes a mounting block and a separate bearing pad connected to the mounting block by screws which may be independently adjusted to establish uniform face-to-face contact between the bearing pad and the rail. The screws also may be quickly released to enable removal and replacement of the bearing pad without disturbing the position of the mounting block.

摘要： The upper level of a pouring conveyor receives sand molds and conveys the empty molds to a pouring station wherein molten material is deposited therein to form castings. Each mold is provided with a supportive weight and jacket before pouring. After the castings have been poured, the molds are transferred to the lower level of the pouring conveyor for cooling purposes, and then back to the upper level to remove the weight and jacket. The sand molds are then transferred to the upper level of a cooling conveyor and are deposited into trays provided on the cooling conveyor. Each tray is adapted to receive a plurality of molds to enable the molds to move from serial to parallel movement. An indexable pusher arm is provided to accurately place each mold in a respective tray to insure proper spacing for uniform cooling. After each tray has traversed the upper and lower levels of the cooling conveyor, the molds are removed from the trays and the sand is broken away to reveal the castings for harvest. The volumetric capacity and cooling time can be adjusted simply by adjusting the number of trays disposed on the cooling conveyor.
摘要翻译： 浇注输送机的上部接收砂模并将空模具输送到浇注站，其中熔融材料沉积在其中以形成铸件。 浇注前每个模具都配有一个支撑重量和外套。 铸件倒出后，将模具转移到倾倒式输送机的下层，以进行冷却，然后回到上层去除重物和夹套。 然后将砂模转移到冷却输送机的上部，并沉积在设置在冷却输送机上的托盘中。 每个托盘适于容纳多个模具以使模具能够从串联移动到平行运动。 提供可转位的推动臂以精确地将每个模具放置在相应的托盘中，以确保适当的间隔以实现均匀的冷却。 在每个托盘已经穿过冷却输送机的上下层之后，将模具从托盘中取出并将砂子分开以露出用于收割的铸件。 容量和冷却时间可以通过调节设置在冷却输送机上的托盘的数量来简单地进行调整。

摘要： A machine for forming foundry moulds includes a turret supporting spaced mould frames, each of the latter having a mould portion formed therein by rotation of the turret toward a sand filling and compacting station and away therefrom. The completed mould portion may be moved to a position where a core can be set thereon and then moved to a position where the mould portions are positioned one atop another to make a stack of finished and cored moulds. When the moulds are not cored, a pair of said filling and compacting stations are provided, the turret oscillating or rotating unidirectionally from a loading position to a delivery position. Where a pair of filling and compacting stations are provided for forming cope and drag mould portions, the turret oscillates to place the two mould portions in proper position to form a mould comprised of cope and drag portions. The machine makes foundry moulds capable of being placed one atop another, a pair of moulds defining a pouring lip connected to a pouring channel in turn connected to runners and mould cavities.
