Definitions

  • the invention relates to a device for the production of openings, for example sprue openings and ventilation bores, in a mold made of compacted molding sand located in a mold top box, preferably produced in a molding machine, mold boxes, in particular a mold top box, being intermittently used by means of a suitable conveying device alternately with a mold lower box, can be moved into a work area above the device.
  • the necessary tools for example funnel milling for the introduction of sprue openings or puncture needles for the production of ventilation bores, are each provided on a positioning device, with the aid of which each associated tool can be moved so that the top of the casting mold is provided with a corresponding opening at any point can be.
  • the positioning devices consist of cantilevers, scales or carriages or the like which are movable perpendicular to one another and are moved by a common drive.
  • Such Positioning devices are required for each of the tools because they cannot be handled together because of their different types of processing.
  • a separate position control must be provided for each tool, with the help of which the tool can be moved quickly and safely into its working position.
  • the object of the invention is to simplify a device of the type specified in the introduction in such a way that it can be used to produce at least two different types of openings.
  • the object is achieved in that the device has a positioning device with the aid of which tools for introducing the openings can be moved in the transverse and longitudinal directions of the casting mold, that a first tool for producing a pouring opening or the like and a second tool for producing a vent hole or the like are separately lockable on a common tool carrier of the positioning device, and that the one tool in a first work positioning of a mold upper box generated by the conveyor and the other tool in the following work positioning of the same mold upper box generated by a conveying cycle for the Making an opening in the mold can be actuated.
  • the working area of such a device accordingly comprises two successive positions of the upper mold box, which are forced by a conveying cycle. Only one of the tools is activated in each of the two working positions of the upper mold box; the other is shut down in the meantime because there is a mold lower box in his work area. If top and bottom boxes are transported one behind the other, the boxes can be transported in two consecutive stations can be processed with different tools without the need for a tool change.
  • a single tool carrier including the necessary supports, drives and controls, is sufficient to make the required openings in the top of the mold, and not only is the outlay for producing such a device considerably reduced, but also the space requirement is reduced, so that the conveyor is much shorter.
  • the arrangement is preferably made such that a tool feed directed vertically upwards takes place, each tool being driven separately.
  • the tool carrier is designed as a cantilever which can be moved in and transversely to the conveying direction of the casting mold on a traverse of the positioning device, which in turn is arranged on a stationary frame of the positioning device, on which the drive for the tool carrier is also located can.
  • the tool carrier is displaceable on the crossmember in such a way that at least one of the tools can be positioned in one position so that the top of the mold can be machined at any point.
  • the mobility of the tool carrier in a favorable manner in the conveying direction is as long as the length of a conveying cycle.
  • one tool is arranged in the conveying direction in front and the other tool in the conveying direction behind the cross member on the tool carrier.
  • the center distance of the tools in the conveying direction is at least equal to the length of a conveying cycle, one being particularly important short execution of the tool carrier results if the tools are attached to the ends of the tool carrier.
  • a conveying device FE transports casting molds from one work station to the next in a conveying direction FR. 1 and 2, the casting molds from compressed molding sand have already been formed and are contained in the mold boxes resting on the conveyor.
  • a top mold box and a bottom mold box alternate on the FE conveyor.
  • the conveyor device FE transports the mold boxes with a certain cycle frequency from one working position to the next, in which they remain at rest for processing.
  • Fig. 1 there is a top mold box 1 in a first working position.
  • the upper mold box 1 is placed on the conveying device FE with the casting mold open, so that its upper side is accessible for processing from below.
  • a mold lower box 1 in the next working position, which is set in front of the upper box 1 in the conveying direction FR by the length T.
  • the length T is the time signature of the conveyor FE.
  • the upper mold box 1 has instead advanced by the length T; the next mold sub-box 1 is now in its place ; while on the mold sub-box 1 no processing takes place, the upper mold box 1 can be processed in succession in the two positions shown in FIGS. 1 and 2.
  • the device according to the invention is set up under the conveyor FE and in the middle between the two working positions. It comprises a stationary frame GE, on which a crossbar TR extending transversely to the conveying direction FR is provided in a stationary manner.
  • a tool carrier WT is freely movable on the crossbar TR both transversely to the conveying direction FR and in the direction thereof, and is equipped with tools 3; 5 which are rigidly attached to the ends E1 and E2 of the tool carrier WT on both sides of the crossbar TR.
  • the first tool 3 is designed as a funnel cutter, with the aid of which a pouring opening can be milled into the casting mold.
  • the second tool 5 is a puncture needle, which can be used to form ventilation bores.
  • a drive 2 sets the hopper cutter in rotation and at the same time gives it the required tool feed WV1, which can be applied by a further drive 4 for the second tool 5 alone.
  • the directional arrows R1 and R2 symbolize the mobility of the tool carrier in the conveying direction FR in the respective work positioning.
  • a drive 6 is symbolically represented on the frame GE, which drives the tool carrier WT in such a way that one of the two tools 3, 5 is ready for operation. It goes without saying that the drive 6 is generally not carried out manually, but is programmed accordingly and, if appropriate, actuated by sensors. The details are customary in the art and have no connection with the invention; therefore they are omitted.
  • FIG. 1 shows an axis spacing A of the tools 3; 5. It is at least equal to the length T, which is both the distance between two mold boxes and that Cycle path is the same. While the tool 3, which can be moved into any position below the upper mold box 1, is activated in the left-hand working positioning in the drawing, the tool 5 can only be activated in the right-hand working positioning shown in FIG. 2. In order to clarify this, the possible movements of the tools 3, 5 are entered when the tool in question can be used. For the sake of clarity, its end position, which is distant from the crossmember TR, is also shown in broken lines.
