Definitions

  • the invention relates to a device for production openings, for example sprue openings and vent holes, in one in a molded top box located, preferably in a molding machine produced mold from compressed molding sand, wherein cyclically by means of a suitable conveyor Mold boxes, in particular one mold top box alternating with a molded sub-box, in a work area are movable over the device, the Device has a positioning device with the Help tools to make openings in cross and Longitudinal direction of the mold are movable, a first Tool for making a gate or the like and a second tool for making one Vent hole or the like on a common Tool carrier of the positioning device provided are.
  • the necessary ones Tools for example funnel milling for the introduction of sprue openings or puncture needles for the production of ventilation holes, each on one Positioning device provided, with the help each associated tool is movable so that the Top of the mold anywhere with a corresponding opening can be provided.
  • the positioning devices consist of vertical cantilevers, scales or Sled or the like, by a common drive be moved. Such a positioning device is required for each of the tools because of them their different types of processing not handled together can be. It is also for everyone Tool to provide a separate position control with which Help the tool into its working position quickly and safely can be moved.
  • DE-U-85 00 372 is a drilling device for attachment of funnel, riser and vent holes Casting molds known from compacted molding sand.
  • This drilling device has a height-adjustable piston a double swivel arm, one at its free end rotatable about a horizontal axis and with different Equipped tools on opposite sides Has tool head.
  • the drilling device is with her tool head over the surface of a molding box swiveling, one of the two opposite Tools are used.
  • the object of the invention is a device to simplify the type specified at the beginning, that with their help at least two different ones Types of openings can be produced.
  • the working range of such a device accordingly includes two consecutive, forced by a funding cycle Positioning of the top mold box.
  • Positioning of the top mold box is in each of the two working positions of the Mold top box activated only one of the tools; the other is shut down because a mold sub-box in his work area located.
  • top and bottom boxes one behind the other transported, so here the boxes in two successive stations processed with different tools, without having to change tools.
  • a single tool carrier including is sufficient the necessary supports, drives and Controls to make the necessary openings in the top the mold, and it’s not just that Effort for the production of such a device considerably reduced, but it also reduces the space requirement, so that the conveyor is much shorter.
  • the arrangement is preferably made so that a vertical tool feed directed upwards, whereby each tool is driven separately.
  • the tool carrier is designed as a boom is in and across the conveying direction of the mold a traverse of the positioning device is movable, the in turn on a stationary frame of the positioning device is arranged, on which the drive for the tool carrier can be. It is advisable when the tool carrier is so slidable on the traverse is that at least one of the tools in each case Position can be positioned that the top of the mold can be edited at any point.
  • the mobility the tool holder is in a favorable manner in the conveying direction as long as the length of a funding cycle.
  • the invention Device is a tool in the conveying direction and the other tool in the conveying direction behind the traverse arranged on the tool carrier.
  • the Center distance of the tools in the conveying direction the length of a Funding cycle is at least the same, with one being special short execution of the tool carrier results if the Tools are attached to the ends of the tool carrier.
  • a conveying device FE transports in a conveying direction FR molds from one work station to the next. 1 and 2 are in the processing state Casting molds made from compacted molding sand and already in the mold boxes on the conveyor contain. One form top box changes each time and a mold lower box on the conveyor FE.
  • the FE conveyor conveys the mold boxes a certain clock frequency from a working position to next in which they remain at rest for editing.
  • Fig. 1 there is a top mold box 1 in one first work positioning.
  • the top mold box 1 With the mold open placed on the conveyor FE so that its top is accessible for processing from below.
  • a mold lower box 1 'in the next working positioning which is by the length T the upper box 1 is set in the conveying direction FR.
  • the Length T is the time signature of the conveyor FE.
  • the upper mold box 1 instead advanced by length T; is in its place now the next mold sub-box 1 '; while on the Form-1 ' no processing takes place, the Mold top box 1 in the two shown in Figs. 1 and 2 Positions can be processed one after the other.
  • the one according to the invention Device set up includes a fixed frame GE, on which one transversely to the conveying direction FR extending truss TR is provided stationary.
  • a tool carrier WT is on the traverse TR both across the conveying direction FR and freely movable in their direction stored, and equipped with tools 3, 5, on both sides the traverse TR at the ends E1 and E2 of the tool carrier WT are rigidly attached.
  • the first tool 3 is as Hopper cutter designed with the help of a sprue is milled into the mold.
  • the second is Tool 5 a puncture needle, which is used to form ventilation holes is usable.
  • a drive 2 moves the Funnel cutter in rotation and simultaneously gives it the required tool feed WV1 by another Drive 4 for the second tool 5 can be applied alone is.
  • the directional arrows R1 and R2 symbolize the mobility of the tool carrier in the conveying direction FR in the respective Work positioning.
  • the rack GE symbolically represents a drive 6, which the Tool carrier WT moves so that one of the two tools 3; 5 is ready to work. It is understood that the drive 6 is generally not carried out manually, but programmed accordingly and, if necessary, sensor-controlled is operated. The details are customary 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 that both the distance between two mold boxes and the Cycle path is the same. While in the in the drawing, respectively left work positioning tool 3 is activated, this in any position below the top mold box 1 is movable, the tool 5 is only in the Right work positioning shown in Fig. 2 can be activated. To illustrate this, the possible movements are of the tools 3; 5 entered when the relevant tool is usable. For clarification in each case also its end position remote from the traverse TR dash-dotted lines.
