Definitions

  • the invention relates to a multi-axis Die casting machine for ceramic articles according to the preamble of claim 1, a system with several of these Die casting machines or a method for operating them.
  • Die casting machines for the production of ceramic articles one or more molds. To the molds for Form and remove a green body open and close To be able to, these in turn consist of two or more Molded parts that are movable in relation to each other. Each the more complex the object to be cast, the more Moldings are required. The molded parts mostly exist made of porous plastic.
  • the mold is placed in the Die casting machine used and by all sides Pressurization using a complex press clamped.
  • the problem here is that the pressure at this clamping of the molded parts in the empty state on the one hand must not be too high to damage or to avoid premature aging of the molded parts. On the other hand must have a sufficiently high clamping pressure in order to Internal pressure of the subsequently pressed slip to be able to withstand.
  • the object of the invention is an improved To propose die casting machine, in particular the Downtimes can be reduced.
  • the rear access enables quick access Replacing molds using e.g. Forklifts and the Use of several close to each other Die casting machines in one system, this also without dismantling transport and / or installed on the front Extraction facilities.
  • conical centering bolts allow one simple and quick alignment Walls or holding and / or pressing devices and the like with swiveling exchange access Effects of wear from the swivel axis, in particular from Hinges off.
  • tensioning devices for pretensioning the Casting mold via an adjustable clamping path which in particular especially with such a structure of a die casting machine is easy to implement, avoids a too high one Pressure load on the mold. This can increase the lifespan and thus the number of castings that can be produced can be increased significantly. In addition, costs for the Purchasing molds saved.
  • a particularly quick clamping of the mold is also possible bayonet-type fasteners with integrated adjustable Attacks possible.
  • Such travel settings with independent inventive step can also when setting others, in particular to be arranged across the exchange side or clamped molded parts are provided.
  • the removal devices and the assembly lines for removing and transporting the leather-hard green parts arranged closer to the removal side of the die casting machines be, which in turn saves space in a machine shop means.
  • FIG. 1 there are one on the front Die casting machine 1 an automatic removal device 2 and a conveyor belt 3 for removal and removal manufactured green compacts arranged.
  • the removal device 2 is next to a basic position with dash-dotted lines in a removal position 2A, in which they can be removed in the die casting machine is retracted, and in one Lowering position 2B for lowering a green compact 4 (in FIG. 3) shown on the conveyor belt 3.
  • the die casting machine 1 comprises, as simplified in the figures is sketched for clamping a die-casting mold 5 in particular an upper and lower press and Holding device 11 and 12, two lateral pressing and Holding devices 13 and 14 and a rear press and Holding device 15.
  • the movements of the opposing pressing and holding devices 11 and 12 or 13 and 14 advantageously synchronized in this way stored and mutually using e.g. Scissors or Toothed rods are coupled that the clamping of the Mold 5 centrally in the die casting machine and on all sides evenly pressurized.
  • the die 5 is in the illustrated Embodiment of five molded parts, an upper one Molding 16, a lower molding 17, two lateral Moldings 18 and a rear molding 20.
  • the Molded parts are interchangeable on the corresponding press and Holding devices 11 - 15 stored.
  • Die casting machine is pivotally mounted about a pivot axis 22.
  • Fig. 2 also provides the die casting machine 1 Operating position also with swung back pressing and Holding device 15.
  • the rear pressing and holding device 15 For swiveling the rear pressing and holding device 15 is a preferably hydraulically driven Cylinder mechanism 23. To align the rear Pressing and holding device 15 to the longitudinal axis of the Die casting machine 1 is used, in particular, to taper Centering pin 24. In the closed operating position the rear pressing and holding device 15 in one simple embodiment by means of a screw 25 on Press frame 21 releasably attached.
  • the pre-stressing of the molded parts by the approach and Fixing the rear pressing and holding device 15 is preferably carried out by means of a particularly preferred Locking and / or locking mechanism 25th With this Stops on screw or locking bolts adjustable stored, whereby only a maximum permissible closing and so that clamping is possible.
  • the attacks are for Adjustment of the permissible preload is preferred slid over the screw or locking bolts and depending on the embodiment in certain or any position can be set.
  • Such a clamping mechanism with its own inventive importance can also be used to clamp the rest Moldings with in particular the then opposite, corresponding molded parts or each of the corresponding holding devices of the molded parts be used.
  • the rear molding 20 or its Holding device 15 also directly between two in the composite mold 5 for this purpose lateral mold parts 16, 17; 18 or their holding devices 11, 12; 13, 14 used and by fixing them together.
  • the outer die casting machines 1 In the system shown in Fig. 3 with several independently operated die casting machines 1 are located the outer die casting machines 1 in the casting operation. In the middle die casting machine 1 is the back pressing and Holding device 15 pivoted away from the press frame 21 and a stacker 30 is currently driving with a new mold 5 back to the open die casting machine 1. In particular, the exchange with the help of forklifts 30, a lot of free access space for their use is allowed when exchanging molds 5 another time saver.
  • the green compacts 4 removed from the die casting machines 1 are from a first conveyor belt 3 to a Transport route relocated where they continue to dry before you ultimately at a cleaning station from the transport route taken and transported to the dryer.
  • a continuation of operation in such a system the other stations or die casting machines possible if with one of these the mold against a new or against one is to be exchanged for other articles.
  • Swivel mechanism e.g. also a sliding mechanism to be provided.
  • Moving the corresponding Pressing and holding device 15 takes place after its release from Press frame 21 up or down or sideways back and forth forth.
  • Embodiments are also included in which the corresponding pressing and holding device 15 entirely is removable, for example on a rail guide or by means of a crane-like suspension on the press frame 21 can be brought up and away from it.
  • Another side of the die casting machine can be used with such a pivoting or sliding mechanism be designed, the top also e.g. in the event of access by crane is expressly included.
