Abstract

A device for supplying to and/or controlling hydraulically operated components of a die casting machine, comprising a base block with a main inlet opening and a main outlet opening for hydraulic medium, and also at least two different module components, which are selected from the group consisting of core-pulling modules, core-pulling-relief modules, booster modules, secondary movement modules, and vacuum modules, and which are fluidically connected to the base block. The present invention relates to a die casting machine with such a device and to a method for supplying to and/or controlling hydraulically operated components of a die casting machine.

First claim

The invention claimed is:

1. A device for supplying to and/or controlling hydraulically operated components of a die casting machine, comprising:
a base block having a main inlet opening and a main outlet opening that transports a hydraulic medium the main inlet opening and the main outlet opening disposed at a side of the base block, and a plurality of base block connection openings and the bottom area disposed at top and bottom sides of the base block, the plurality of base block connection openings discharging and introducing the hydraulic medium, wherein the main inlet opening and main outlet opening are connected to the top and bottom side base block connection openings by fluidic lines in the base block;
at least two different module components selected from the group consisting of core-pulling modules, core-pulling-relief modules, booster modules, secondary movement modules, and vacuum modules, each of the at least two different module components having module connection openings disposed at top and bottom sides thereof, the module connection openings discharging and introducing the hydraulic medium, and interior fluidic lines connecting the top and bottom side module connection openings,
wherein at least one of the two at least two different module components is arranged at the top side or the bottom side of the base block such that the module connection openings thereof form a fluidic connection with the corresponding base block connection openings, and
wherein the at least two different module components have fluidic connections to the hydraulically operated components of the die casting machine; and,
end plates that close unconnected inlet openings and outlet openings of the base block and/or of a connected module component.

2. The device according to claim 1 , wherein at least one further module component is arranged at a top side or a bottom side of at least one of the at least two different module components, the at least one further module component is selected from the group consisting of core-pulling modules, core-pulling-relief modules, booster modules, secondary movement modules, and vacuum modules, and the at least one further module component has, at top and bottom sides thereof, further module connection openings discharging and introducing the hydraulic medium, and interior fluidic lines connecting the top and bottom side further module connection openings,
wherein the at least one further module component is arranged at a top side or a bottom side of an adjacent module component such that the corresponding further module connection openings of the at least one further module component form a fluidic connection with corresponding adjacent module connection openings of the adjacent module component, and
wherein the at least one further module component has fluidic connections for connecting to the hydraulically operated components of the die casting machine.

3. The device according to claim 1 , wherein the base block and the at least two different module components are connected by fastening means comprising one or more threaded rods.

4. The device according to claim 1 , wherein a distribution unit having at least one fluidic connection is connects to the hydraulically operated components of the die casting machine.

5. The device according to claim 1 , wherein the base block has a fluidic connection to the hydraulically operated components of the die casting machine.

6. The device according to claim 1 , wherein the base block, and at least one of the at least two module components include a valve that modifies flow of the hydraulic medium.

7. The device according to claim 6 , wherein the base block or the at least one of the at least two module components include an operating element, and the base block connection openings, the module connection openings, and the operating element are arranged on a same side opposite the main inlet opening and the main outlet opening of the base block.

8. The die casting machine according to claim 1 , wherein at least one or more of the base block, the at least two different module components, the end plates, and any additional module units or operating elements, are connected by fastening means.

9. The die casting machine according to claim 8 , wherein the die casting machine furthermore comprises at least one receiving frame that receives at least one energy module, the at least one receiving frame comprising:
fastening means for fastening the at least one receiving frame on the die casting machine,
at least one row that receives the at least one energy module, wherein the at least one row comprises two profile pieces which are connected to one another by a respective connecting piece or energy module thereby forming a quadrangular interior space,
wherein the at least one row has means for arranging the at least one energy module in the interior space thereof,
wherein the fastening means that fastens the at least one receiving frame on the die casting machine is arranged on a row forming an outer face of the at least one receiving frame, and the at least one receiving frame is fastened to the die casting machine via the fastening means,
wherein the base block includes a main inlet opening and a main outlet opening for the hydraulic medium arranged on a rear side of the base block,
and the plurality of base block connection openings are disposed in the top side and the bottom side of the base block discharge and introduce the hydraulic medium, wherein the main inlet opening and main outlet opening are connected to the plurality of base block connection openings by fluidic lines in the base block,
the at least two different module components selected from the group consisting of core-pulling modules, core-pulling-relief modules, booster modules, secondary movement modules, and vacuum modules, each have the module connection openings in a top side and a bottom side thereof that discharge and introduce the hydraulic medium, and fluidic lines in their respective interiors that connect the module connection openings,
wherein at least one of the at least two different module components is arranged in the top side or the bottom side of the base block such that the corresponding module connection openings of the at least one module component forms a fluidic connection with the corresponding base block connection openings of the base block,
wherein the at least one of the at least two different module components have connections that connect to the hydraulically operated components of the die casting machine, and,
the end plates close unconnected inlet openings and outlet openings of the base block and/or of the at least one module component,
wherein the device is arranged in the at least one row of the receiving frame that is disposed adjacent to the die casting machine.

10. The die casting machine according to claim 9 , wherein the device is arranged in the at least one row of the receiving frame adjacent to the die casting machine such that the base block of the device connects the profile pieces of the at least one row at a bottom thereof.

11. The die casting machine according to claim 9 , wherein 1 to 5 core-pulling modules are arranged above the base block, 1 to 5 booster modules are arranged above the core-pulling modules, and 1 to 5 secondary movement modules are arranged below the base block.
