Abstract

Apparatus for transporting and guiding a portable furnace to transfer molten material from the furnace to a die cast machine includes a platform which supports the furnace. The platform has wheels at one end and fixed legs at the other end. The wheels roll on rails secured to the floor which guide the platform to a predetermined position, and a stop locates the platform in the proper position. The furnace is placed on the platform when the platform is in an aisle adjacent the machine, and the platform is pushed into place by lifting the fixed legs and pushing the platform. After the operation of the machine, the furnace can be removed by pulling the platform into the aisle and lifting the furnace off of the platform. The furnace can then be moved to another platform to transfer molten material to another machine.

Claims

1. A method for transporting a portable furnace in a common area and locating the furnace among at least two die cast machines located on a floor outside of and adjacent to the common area, the furnace being selectively placed in a predetermined location with respect to each of the machines, the predetermined locations also being outside and adjacent the common area, comprising the steps of

placing a movable platform adjacent to each of the machines,

securing rail means to the floor for guiding each of said platforms,

securing stop means relative to each of the machines for precisely positioning said platforms with respect to the machines,

each of said platforms having at least one wheel which is guided by said rail means, and at least one fixed leg for securing the platform in place,

said platforms further having means for abutting against said stop means, stopping said platforms in the predetermined locations,

moving a selected platform into the common area,

placing the furnace on said selected platform, and

pushing said selected platform out of the common area to its predetermined location, said selected platform being guided by said rail means until said abutting means abuts against said stop means for proper placement of said selected platform with respect to its respective die cast machine.

2. A method of making die cast piece parts comprising the steps of

placing a die in each of a plurality of die cast machines, said machines being located on a floor adjacent a common area,

placing a furnace platform adjacent each of said machines, said furnace platforms being movable from a first predetermined position with respect to said machines and a second position in said common area,

moving one of said platforms into said common area,

placing a portable furnace on said platform,

moving said platform to said first predetermined position,

transferring molten material from said furnace to said machine,

moving said platform from said first predetermined position to said common area, and

removing said furnace from said platform.

3. Apparatus for transporting a portable furnace to a die cast machine and placing the furnace in a predetermined position with respect to the machine comprising

platform means for supporting the furnace,

means for placing the furnace on said platform means and removing the furnace from said platform means,

said platform means having wheel means at one end and position fixing means at the other end,

means for guiding said wheel means end of said platform means to the predetermined position, and

means for lifting said position fixing means end of said platform means to move said platform means to and from the predetermined position.

4. The apparatus of claim 3 wherein said wheel means abuts against stop means secured with respect to the machine such that said wheel means abuts against said stop means when the furnace is in the predetermined position.

5. The apparatus of claim 3 wherein said wheel means includes at least two wheels, said guiding means comprising a rail for each of said wheels.

6. The apparatus of claim 5 wherein said wheels include a circumferential groove for said rails, said wheels being supported by a surface on which said rails are secured.
