Definitions

  • the invention relates to a slot nozzle expulsion device for dismantling slot nozzles from core boxes, mold plates, molds etc. and to a corresponding method.
  • Essential component e.g. of a core box are slot nozzles that have a large number of fins.
  • Sand is introduced into core boxes equipped with such slot nozzles, the sand mass introduced into the respective core box containing a resin or various resins.
  • the air previously present in the core box escapes through the slot nozzles; some of the resin introduced with the sand mass escapes with the air; this has the consequence that the slot nozzles or the openings formed by their lamellae become blocked. Cleaning the slot nozzles is only possible to a limited extent and is comparatively complex.
  • the invention has for its object to provide a slot nozzle expulsion device for dismantling slot nozzles from core boxes, mold plates, molds etc. or a corresponding method by means of which or in which a largely non-destructive disassembly of the slot nozzle is realized with the least possible effort.
  • a slot nozzle expulsion device which has a nozzle expulsion tip which can be inserted into a space between two lamellae of a slot nozzle, an anchor which is arranged at the free end of the nozzle expulsion tip, the transverse dimension of which is smaller and the longitudinal dimension of which is larger than that of the space accommodating the nozzle expulsion tip between the two fins of the slot nozzle, and which, as soon as the nozzle expulsion tip protrudes beyond the inside of the slot nozzle, can be brought into contact with the inner edges of the fins of the slot nozzle by rotation of the nozzle expulsion tip, and has a drive element which is arranged on an anchoring-away section of the slot nozzle expulsion device and can be acted upon with impact energy, by means of which the slot nozzle expulsion device and you the slotted nozzle gripped by the anchor on the inner edges of its slats with respect to the core box, the mold plate, the mold etc.
  • the nozzle expulsion tip is inserted into a space between two slats of a slot nozzle until its free end protrudes through the slot nozzle; then the nozzle expulsion tip is rotated until the armature arranged at the free end of the nozzle expulsion tip lies against the inner edges of the slats of the slot nozzle; thereupon impact energy is applied to the drive member which is firmly connected to the nozzle expulsion tip until the nozzle expulsion tip and with it the slot nozzle, which the armature engages on the inner edges of its lamellae, is moved out of the core box, the mold plate, the mold, etc.
  • the drive member is arranged at the end of the slot nozzle expulsion device remote from the anchor.
  • This drive member can advantageously be designed as a handle, by means of which the passage of the nozzle expulsion tip with the armature through the slot nozzle can be facilitated.
  • a guide rod is provided between the drive member and the end of the nozzle expulsion tip on the drive member, on which a striking member is slidably mounted, multiple strikes of the striking member against the handle or the driving member can exert a force acting exactly on the drive member in the desired direction of movement, whereby the risk of damage to the seat surface of the core box-side recess is further reduced.
  • the striking member is designed as a striking ring which is rotationally symmetrical with respect to the longitudinal axis of the guide rod and the drive member, since then inevitably an impact energy is introduced which is exactly parallel to the desired direction of movement and uniform with respect to the axis of this direction of movement becomes.
  • a stop is arranged on the end portion of the guide rod on the nozzle ejection tip, by means of which the longitudinal movement of the striking member along the guide rod can be limited.
  • the nozzle expulsion tip can be detachably connected to the end of the guide rod on the nozzle expulsion tip side. This means that the appropriate nozzle expulsion tip can be used for the slot nozzle to be dismantled be connected to the nozzle ejection tip end of the guide rod.
  • connection between the guide rod end of the nozzle expulsion tip and the nozzle expulsion tip end of the guide rod can expediently be used as a form-fitting plug-in, thread, bayonet connection or the like. be trained.
  • a firing pin belongs to the slot nozzle expulsion device by means of which a lamella of the slot nozzle can be destroyed and removed from the space between the two lamellae adjacent to this destroyed lamella.
  • a lamella or possibly also several lamellae can then be destroyed until the nozzle expulsion tip with the anchor provided at its free end can be inserted into the slot nozzle through the resulting space or the anchor can be guided through this slot nozzle.
  • An embodiment of a slot nozzle expulsion device 1 according to the invention shown in the basic illustration in FIG. 1 is used to disassemble a slot nozzle 2 shown in the basic illustration in FIG. 4 from core boxes, mold plates, molds etc.
  • the slot nozzle expulsion device 1 is divided into a nozzle expulsion tip 3 and a guide rod 4.
  • the nozzle expulsion tip 3 and the guide rod 4 can be detachably connected to one another.
  • a connection 5 is used, or the like in a suitable manner as a threaded, plug-in, bayonet connection. can be trained.
  • the detachable connectivity between the nozzle ejection tip 3 on the one hand and the guide rod 4 on the other hand is provided in order to be able to connect different nozzle ejection tips 3, which differ in terms of their dimensions, in particular their length, etc., to the guide rod 4.
  • the appropriate nozzle ejection tip 3 is connected to the guide rod 4 for the slot nozzle 2 to be dismantled in each case.
  • the nozzle expulsion tip 3 is connected in a rotationally fixed manner to an armature 7 via a connecting pin 6.
  • This anchor protrudes perpendicularly from both sides of the drawing plane selected in FIG. 1 and is shown in a bottom view in FIG. 2.
  • the guide rod 4 has, at its end opposite the nozzle expulsion tip 3, a grip piece 8 also serving as a drive member, which in the exemplary embodiment shown is connected by a threaded connection 9 to the end of the guide rod 4 remote from the nozzle drive tip.
  • a rotationally symmetrical to the longitudinal axis 10 of the guide rod 4 or the handle 8, serving as a striking ring 11 is slidably mounted.
  • the longitudinal movement of the impact ring 11 on the guide rod 4 is limited by the handle 8 at the upper end of the guide rod 4 in FIG. 1 and by a stop 12 at the lower end of the guide rod 4 in FIG.
  • the handle 8 can be subjected to impact energy by moving the impact ring 11 upwards along the guide rod 4.
  • Both the handle 8 and the hammer ring 11 are provided with circumferential recesses 13 and 14 in the illustrated embodiment, so that their handling is easier.
  • the nozzle expulsion tip 3, with its free end having the armature 7 must be passed through an intermediate space 15 between two fins 16 of the slot nozzle 2.
  • the longitudinal sides of the armature 7 are arranged parallel to the lamellae 16 delimiting the intermediate space 15. If the space 15 between two fins 16 is too small to allow the nozzle expulsion tip 3 provided with the armature 7 to be passed through, a fin 16, preferably one of the middle fins 16, of the slot nozzle is destroyed by means of a firing pin 17 shown in FIG. 3 and removed or pushed out of the slot nozzle 2. If necessary, two or more slats can also be destroyed.
  • the nozzle expulsion tip 3 with the armature 7 arranged at its free end is passed through the intermediate space 15 between two fins 16 of the slot nozzle through the latter.
  • the slot nozzle expulsion device is rotated or rotated, preferably by 90 degrees.
  • the armature 7 can be brought into abutment against the inner edges of the fins 16 of the slot nozzle 2.
  • the hammer ring 11 is moved at high speed against the handle 8 of the slot nozzle expelling device 1, which is designed as a drive member. This movement of the impact ring 11 in the direction of the handle 8 is repeated until the slot nozzle expelling device 1 and with it the slot nozzle 2 are so far from the core box that the slot nozzle 2 is separated from the core box.
