Definitions

  • the invention relates to a hot chamber die casting machine one placed in a metal bath inside a crucible Pouring container with a riser pipe with mouthpiece and one attached to this nozzle and two with their Axes of drive units aligned parallel to the nozzle, on the one hand with a crossbeam assigned to the crucible Machine stand and on the other hand with the fixed Form plate of a clamping unit are connected to one Half of a mold is attached, the sprue bushing during the casting process can be pressed against the nozzle tip.
  • the invention has for its object the drive units for the approach of the mold to the nozzle that a time-optimized and sensitive feed control is achievable.
  • the linear drive can designed as a spindle drive and also with be surrounded by a continuous cooling jacket. It is possible, also to equip the servo motors with water cooling.
  • a rack and pinion drive is also a linear drive conceivable, although the spindle drive has proven to be advantageous Has.
  • the slope finally can be designed so that it acts self-locking, so that an unwanted feed or return of the drive is prevented is and the necessary during the die casting process Holding pressure can be maintained.
  • the engine load moments are like this fixed that a secure closure between the sprue bushing and the tip of the nozzle is guaranteed.
  • the servomotors can be used operated at different speeds, the Arrangement is made so that the feed rate opposite of the drive just before the nozzle tip is applied the feed rate is greatly reduced. It's going on this way it is possible to regulate the sprue neck finely to approach the nozzle tip. This can cause wear largely avoided at this point. It is well known the nozzle tip hardened and settles in a very small Contact area on the sprue bush. If it is too hard Stop can therefore damage the tip of the nozzle, what avoided by the inventive design becomes.
  • FIG. 1 shows a hot chamber die casting machine, on the base frame designed as a machine stand 1 and above a machine base 2 on the left Side of the locking part 3 of the machine with the guide rods 4 for a movable platen 5 with an adjustment drive 6 and a known toggle lock mechanism 7 and a stationary mold platen 8 is arranged.
  • This fixed platen 8 is a movable on rails 9 (Fig. 4) Furnace 10 associated with a crucible 11 by a Traverse 12 is spanned.
  • On the traverse see Fig. 2 and 3) is the outer cylindrical housing 13 of two Spindle drives 14 arranged parallel to one another are fastened.
  • This spindle 16 is one electric servo motor 17, whose axis of rotation 18th approximately perpendicular to the surface 10a of the furnace 10 (Fig. 4) and thus approximately vertically to the footprint 19 of the hot chamber die casting machine is aligned.
  • the two of them Servomotors 17 controlled synchronously with each other, so that the Platen 5 is exactly parallel. An uneven one Force applied by the two spindle drives is excluded.
  • FIG. 2 it dips into the crucible 11 in a known manner, a casting container 26, the top through the traverse 12 with a piston drive 27 for one not shown, immersed in the casting container 26 Piston is applied.
  • This casting container 26 has in Area within the arranged in the crucible 11 Melt a riser pipe that is approximately parallel to the casting container 26 leads from the end of the pouring container upwards and onto it Mouth a nozzle 29 is placed. This nozzle 29 is in the Position of the die casting machine according to FIGS.
  • the total stroke of the downward movement is used for set-up and service purposes on the nozzle 29, the casting container 26 and the nozzle tip 29a and for the process technology in this area necessary modules used.
  • the axes are 18 of the servomotors 17 arranged approximately vertically, and the servomotors close via an angular gear 15 on the spindle 16 on.
  • This configuration therefore causes the electrical Servomotors 17 as far from the surface as possible 10a of the furnace 10 and the crucible are removed.
  • the effect of heat from the oven can therefore largely be ruled out be so that it becomes possible in this way, electrical Servomotors that are very fine in different speed levels are adjustable, even for the rough operation of a Hot chamber die casting machine as drives for starting and stopping to use the nozzle.
  • With water-cooled servomotors 17 and additional heat conducting plates 35 and an integrated Cooling jacket 36 the furnace heat radiation is reduced to the extent that this has no adverse effect on the function that has drives.
  • the sprue bush 30 feed very quickly to the nozzle 29, but then by reducing the feed rate accordingly Approach the nozzle tip 29a very slowly and sensitively to shape any damage to the nozzle tip or the Avoid form.
  • This can be done by regulating the two Spindle drives can be achieved when starting (and also when driving down) a so-called target braking on the contact point used there. The contact point is in a search determined. Then the adjustable contact pressure is exceeded a torque control of the motors built. This facility would therefore allow the contact pressure (between the nozzle and sprue sleeve) of those required for the melt in the mold Adjust press force and this adjustment after a mathematical formula.
  • the thread of the spindle 16 and the counter thread 20 of the spindle nut 21 can be designed to be self-locking are. After the sprue bushing 31 has been placed on the nozzle tip 29a and switching off a drive can therefore Nozzle is kept stable and firm in its operating position, the prerequisite, of course, is the design of the drive thread on the high forces to be expected when Die casting is to be designed. The engine relief torques are additional adjusted so that a secure closure between Sprue bushing and nozzle tip is guaranteed.
