Definitions
- the invention relates to a device for supplying sprayers for die casting machines, each with a liquid containing water and additives for cooling, cleaning and / or lubricating purposes, for application to the inner wall of open molds, according to the preamble of claim 1.
- the opened mold is wetted on the inside with a liquid containing water and additives, dissolved, suspended or emulsified therein.
- the liquid is used for separation, cooling and / or lubrication.
- the composition of the liquid depends on the material and shape of the castings, in particular on their wall thickness, and on the conditions for quick and easy demolding.
- the liquid is sprayed onto the walls of the mold. It is known to connect a spray device arranged on a die casting machine to a container from which the liquid is conveyed by means of compressed air to the nozzles of the spray device (practice of die casting production by E. Brunhuber, 1980, ausverlag Schiele and Schön GmbH, page 128).
- Liquids with different compositions and different spraying devices adapted to the respective casting mold are often required for different casting molds. If the liquid supply in the container is not exhausted when the mold is changed, the container must be emptied and filled with a mixture which is matched to the other mold. In addition, the capacity of the container may not be sufficient for a larger series of the same mold. The die casting process must then be stopped in automatic mode when the liquid supply in the container is exhausted.
- US-A-4,186,769 describes a process in which a concentrate is added to a dilute liquid as it is being pumped from a first container to a casting machine or into a second container in such a way that a liquid of the desired concentration is present which is fed to the casting machines in order to be conducted there in a closed circuit.
- the invention has for its object to develop a suitable for automatic operation device for supplying one or more sprayers for die casting machines, each with a liquid containing water and additives for cooling, cleaning and / or lubricating purposes.
- the object is achieved by the measures described in claim 1.
- the device specified in claim 1 it is possible to set the desired mixing ratio with the mixing valve on the respective die casting machine. In this case, only the amount of liquid specially tailored to the respective casting mold is required for the individual spraying operation.
- the setting can be made in a short time. The production process is therefore no longer affected by time-consuming refilling or decanting of the liquid for the spraying operation.
- the die casting machines can be better exploited with the device described in claim 1, since there are fewer set-up times.
- the principle of the invention is to store liquids with the highest necessary concentration and to carry out the required dilution with water for each casting process before spraying.
- a number of central containers is provided corresponding to the type of casting materials to be processed in the die casting machines, in which in each case liquids from water and additives are stored in the highest concentration required for the respective casting material in a corresponding shape, the central containers are connected via switching valves to a pipeline system to which the mixing valves are closed.
- the type of die casting material to be processed e.g.
- the changeover to the suitable spray liquid takes place by opening the valve between the manifold and the central container provided for the respective material and by adapting the mixing valve setting to the material and the mold used.
- the spray liquid a change can be carried out quickly and easily.
- the central containers are preferably arranged higher than the die casting machines.
- the liquids thus get from the containers to the mixing valves under the influence of gravity. This eliminates the need for complex and energy-consuming subsidies.
- the delivery device is designed as a piston pump, the cylinder of which is either vertical or can assume any other position if it is ensured that gravity does the necessary work via the media.
- no pump is required for the conveyance and mixing of the respective liquids until the interior of the cylinder is filled with the mixture. These processes take place under the influence of gravity. The device therefore works particularly economically.
- the piston of the respective piston pump preferably has two disks which are arranged at a distance from one another, one of which faces the cylinder space intended for holding the liquid and the other faces the cylinder space which can be acted upon by a compressed gas and with which the space delimited by the two disks over a check valve can be connected when the excess pressure is removed.
- liquid which penetrates into the intermediate space during the pumping out of the cylinder chamber filled with liquid can get into the cylinder chamber which is no longer under gas pressure and can escape therefrom after the pumping process.
- the piston consisting of two disks, the problem of sealing against the liquid and against the compressed gas can be easily solved.
- the cylinder space to which pressurized gas can be applied can expediently be connected to the compressed air source provided for the sprayer via a changeover valve.
- the same source of compressed air can therefore be used to actuate the pump and the sprayer.
- a check valve is arranged at the outlet of the cylinder chamber to which liquid can be applied.
- the pump can be installed at a suitable location below the sprayer.
- the check valve prevents liquid from flowing back from the sprayer to the pump or that the sprayer releases drops.
- a preferred embodiment of a mixing valve consists in that a cylindrical body rotatably arranged in a housing has a central cavity which is open on one side and a radial slot which can be rotated in relation to two inlet openings in a housing wall for the liquid and for water, with the inlet cross-sections changing in opposite directions is, with check valves upstream of the inlet openings.
- the check valves prevent the liquid in the cylinder from flowing back when the cylinder is pumped out into the central container.
- the cylindrical body can be provided with a lever, one end of which is designed as a display tip for a scale. This embodiment enables the mixing ratio to be set by hand.
- the cylindrical body with a motor drive and to detect the angular position of the cylindrical body via a position indicator.
- a potentiometer which gives an analog display, or a coding disk, with which the position can be recorded digitally, is suitable as the position reporting device.
- a geared motor can be used as the motor drive.
- the cylinder of the pumps is preferably composed of two disks and a cylindrical jacket arranged between the disks. This embodiment can be produced economically. It is sufficient if the cylindrical jacket is relatively thin-walled. Stops can be provided in the cylinder to limit the stroke of the piston. The suction volume of the cylinder and thus the amount of liquid to be sprayed can be specified by adjusting the stops.

- the liquids to be sprayed consist of water with additives, which can be graphite, pigments or the like in connection with special active substances and carriers. In many cases, emulsifiable, pigment-free additives are also used.
- Liquids with different compositions are often required for different forms 18, 20 and different casting materials.
- the sprayers 14, 16 also often have to be replaced or readjusted to adapt to a different mold.
- a device which has at least one central container 26 for the spray devices 14, 16.
- the container 26 contains water with the additives in the highest required concentration. The concentration is set to the mold and the casting material that require the highest proportion of additives for the production of perfect castings.
- the additives can e.g. B. be diluted 1:50 or 1:80 with water. If different additives are required for different casting materials, eg aluminum or zinc die casting, further central containers with liquids are to be provided in which the corresponding additives are dissolved in the highest necessary concentration. In Fig. 1 only a further central container 28 is shown. If necessary, several central containers can be provided.

- the housing 72 of the mixing valve 38 or 40 is fastened on the disk 62 of the pump 46 or 48 in such a way that the cutout 82 is aligned with an inlet 108 in the disk 62.
- the inlet 108 opens into a cylinder space 110 within the cylinder 112 formed by the disks 62, 64 and the casing 60, in which a piston 114 is slidably arranged.
- the piston 114 contains two piston disks 116, 118 which are arranged at a distance from one another and are connected to one another via a central pin 120. Below the disc 118 there is a cylinder space 122 which can be connected via a bore 124 to a compressed air source 126 which also feeds the sprayers 14, 16.
- a check valve 128 is located in the piston disc 118, via which the intermediate space 130 delimited by the piston discs 116, 118 can be connected to the cylinder space 122 if there is no overpressure in the cylinder space 122.
- the cylinder space has an outlet opening 132 which is arranged in the disk 62 and into which a connecting piece 134 is screwed.
- the outlet opening 132 has at its end facing the cylinder space 110 an annular projection 136 against which a cover 138 is pressed in a spring-loaded manner.
- a spring 140 is supported on a shoulder in the connecting piece 134 and on the cover 138.
- the lid 138 forms a check valve with a projection 136 and the spring 140.
- the liquid provided with the additives in the highest required concentration passes from the containers 26 and 28 via the lines 30, 32 to the changeover valve 34, through which the container 26 or 28 is selected.
- the setting of the changeover valve 34 defines the connection of the container 26 or 28 to the pipeline system 36, which is expediently provided with an outlet tap with which the liquid still present in the line system can be removed before switching to another container.
- the liquid reaches the connecting pieces 68 of the mixing valves 38, 40 via the piping system 36.
- Water enters from the container 44 via the piping system 42 into the connecting pieces 70 of the mixing valves 38, 40.
- the valve plates 90, 92 are opened under the force of gravity of the liquid or water, so that the liquid and the water each reach the body 76 via the recesses 86 and 88.
- the liquid and the water mix in the slot 84 and in the recess 82.
- the mixture passes through the inlet 108 into the cylinder space 110, which fills with the liquid mixture, the mixing ratio of which depends on the angular position of the slot 84.
- the angular positions of the slots 84 in the mixing valves 38, 40 differ.
- Switching valves 142, 144 are located between the compressed air source 126 and the bores 124, which can be operated by hand or by a control.
- the cylinder space 122 In the rest position of the piston 114, the cylinder space 122 is placed at atmospheric pressure via the changeover valves 142, 144.
- the piston 114 bears against stops 146 designed as screws, which are screwed into the disk 64 and limit the stroke of the piston 114.
- the maximum available volume of the cylinder space 110 for the liquid mixture and thus the amount of liquid intended for spraying are determined via the stroke path with the stops 146.
- liquid which has entered the intermediate space 130 between the piston disk 116 and the jacket 60 can enter the cylinder space 122 via the check valve 128 and escape from there into the atmosphere.
- the cylinder spaces 122 are each connected to the compressed air source 126 via the changeover valves 142, 144.
- the piston 114 is moved upward when pressurized with compressed air. B. a working pressure of 0.7 MPa (7 bar) is generated.
- the check valves in the mixing valves 38, 40 close under the pressure prevailing in the working space, so that no liquid is pumped back out of the cylinder space 110 into the containers 26, 28, 44.
- the liquid leaves the cylinder space 110 via the outlet opening 132 and enters the pipes 50 and 52, which run to the sprayers 14, 16.
- the cylinder chamber 122 is placed at atmospheric air pressure by the changeover valves 142, 144, which can be electromagnetically actuated control valves.
- the check valve consisting of the elements 136, 138, 140 closes, as a result of which a return flow of liquid from the sprayers 14, 16 and the pipelines 50, 52 is prevented.
- This check valve is set so that it closes when the pressure in the cylinder space 10 drops to 0.2 MPa (2 bar).
- dripping on the spraying devices 14, 16 is advantageously prevented, so that there can be no undesirable influencing of the surface of the open mold 18, 20 by drops.
- the pumps 46, 48 are arranged lower than the sprayers 14, 16.
- the piston 114 which can be rotated in one piece, has a certain axial extent, so that a low pressure is sufficient to actuate the piston 114. If liquid gets into the intermediate space 130, this is removed via the check valve 128. This ensures that piston 114 operates smoothly and correctly. Since the cylinder 112 is operated at low pressure, the jacket 60 can be thin-walled.
- the level control makes it possible to design the central containers 26, 28, 44 with a small volume.
- a feed from the water supply network can also be carried out, with a pressure reducing valve being used to adapt the pressure to the pressure at the mixing valves 38, 40 which is dependent on the installation height of the containers 26, 28.
