Definitions
- the invention relates to a device for filling shot heads with molding materials, with a storage container for molding material, an outlet member for discharging the molding material into the shooting head and a closure device for closing the filling device comprising the outlet member, the filling device for immersing the Exhaust member is vertically movable in the shot head to be filled on a machine frame.
- Core shooters have been known in foundry technology for many years.
- the foundry cores or molds are usually produced in separate parts, brought together and connected to one another to form a casting mold.
- An essential part of the core shooters are the so-called shot heads with the shot plates carrying the shot nozzles.
- Molding sand, especially core sand, i.e. Quartz sand already mixed or coated with binding agent is poured into the shot heads in question and from there is blown or shot into the respective molds with very high air pressure through the nozzles arranged in the shot plate.
- the present invention is therefore based on the object of designing and developing a device for filling shooting heads of the type in question in such a way that reproducible filling of the shooting head is possible with simple design means, taking into account the actual filling state of the shooting head .
- the device according to the invention for filling shot heads achieves the above object through the features of patent claim 1.
- the device according to the invention is designed in such a way that the outlet member is assigned a contactless sensor that measures into the shot head to detect the state of filling in the shot head is.
- a contactless sensor for detecting the actual filling condition in the shot head is assigned to the outlet member, this sensor measuring into the shot head. Consequently, the sensor can also be used to easily determine whether the shot head is working properly, namely the correct amount of molding material is being dispensed per shooting operation.
- a shot head can be filled with the device according to the invention, taking into account the actual filling state, so that, with the appropriate setting, a predeterminable fill level can always be set within the shot head.
- an ultrasound sensor as the sensor, which regardless of the material
- the presence of molding materials within the shot head, ie the fill level in the shot head, can be detected.
- the attachment of the sensor it is advantageous to assign it to the lower region of the outlet member, above the closure device. More specifically, the sensor could be attached to the outer wall of the outlet member, which in turn could be designed as a tubular extension of a funnel-shaped storage container. In any case, it must be ensured that the sensor does not hinder movement of the outlet member within the firing head, so that the sensor could advantageously be fixed exactly above the maximum immersion depth of the outlet member in order to avoid any obstructions. Any hindrance to the movement of the outlet member would therefore be excluded.
- the filling of the shot head and thus the opening and closing of the closure device could be controlled by a signal from the sensor. If the sensor determined an insufficient fill level, the closure device would be opened and molding material could flow in. When the desired fill level has been reached, the closure device is closed - again on the basis of a signal from the sensor - so that no further molding material can get into the shot head. After a known smoothing of the surface of the molding material then located in the shot head, further refilling in accordance with the above explanation may be necessary in accordance with a new detection result of the sensor.
- the sensor prefferably provides a signal for closing the closing device when the immersion depth of the outlet member, which can also be predetermined, is detected, upon detection of the fill level which can also be predetermined and which corresponds to the maximum depth of immersion.
- FIG. 1 a schematic representation of an embodiment of a device according to the invention for filling shot heads, the outlet member being indicated in an upper and a lower position immersed in the shot head and carrying a sensor for detecting the fill level.
- the single figure shows a device for filling shot heads 1 with molding materials 2.
- This device has a storage container 3 for molding materials 2, an outlet member 4 for discharging the molding material 2 into the shooting head 1 and a closure device 5 for closing of the outlet member 4 comprising filling device 6.
- the filling device 6 is held vertically movable for immersion of the outlet member 4 in the shooting head 1 to be filled on a machine frame 7 which is only indicated.
- the outlet member 4 is provided with a contactless sensor 8, which measures into the shooting head 1, for detecting the filling condition in the shooting head 1.
- This sensor 8 is only activated when the filling condition in the shooting head 1 is to be determined or when the Information about the filling state in the shot head 1 is required before and / or during the filling of the shot head 1.
- the sensor 8 provided here is designed as an ultrasound sensor. It is assigned to the lower area of the outlet member 4, the sensor 8 being specifically attached to the outer wall 9 of the outlet member 4, which is tubular here. The height of the sensor 8 is determined in such a way that when the outlet member 4 is immersed in the firing head 1 there can be no obstruction to the movement of the outlet member 4 and thus no damage to the sensor 8.
