Definitions

  • the invention relates to a molding device for the production of castings, in particular of complex shaped castings such as engine blocks with cylinders arranged in series, for example 2 to 8 cylinders.
  • the molding device is particularly applicable in die casting machines.
  • the U.S. Patent 5,865,241 discloses a die casting machine for making V-motor blocks in a solid and movable mold-half mold.
  • the movable mold half comprises, in addition to the mold cavity, a column-guided ejector block.
  • the cylinder extends beyond the form-facing side of the clamping plate.
  • the Auswerferbox is a massive plate which receives a part of the former cylinder and which is trapezoidal in cross-section.
  • a double-acting ejector cylinder with inserts for the engine cylinders is also arranged, whose imaginary extended axes intersect in the mold cavity. Due to the attachment of these cylinders on the slopes, horizontal and vertical force components on the ejection box become effective during ejection.
  • a similar mold and die casting machine describes the WO 2004/033131 in which two further hydraulic cylinders are provided for moving the movable mold half are. This cylinder arrangement also protrudes clearly beyond the form-facing side of the movable mold half.
  • the shapes described are structurally complex and large and therefore it is very large masses in the die casting machine to move.
  • the invention is therefore based on the object to provide a method and a molding device for the production of engine blocks of in-line cylinder engines, which allows a change of specific operations such as water jacket inserts with less expenditure of time.
  • the object is solved with the features of the claims.
  • the water jacket insert (with sleeves) is designed as a slide, which is detachably connected to the machine ejector.
  • the invention is based on the knowledge known per se that a longer service life of a water jacket insert can only be achieved if it is less in contact with the cooling melt, resulting in lower repair costs.
  • a vertically arranged forming device in a die casting machine includes a fixed platen 1 with a fixed mold half 2 and a movable platen 5 with a movable mold half 4.
  • the movable mold half 4 has a recess 3 for the stroke of a movable contour insert 11.
  • An ejection unit 7 of the die casting machine has connecting rods 8 to the movable mold half 4 and locking bolt 10 between the movable mold half 4 and movable platen 5.
  • On the movable platen 5 cylinders 9 of a hydraulic quick clamping system of the mold are arranged.
  • connection 6 is provided between movable contour insert 11 and ejector unit 7.
  • the water jacket insert (contour insert 11) with sleeves is designed as a slide and firmly connected to the ejector unit 7.
  • the slider is guided with four connecting rods 8 (guide columns) in the machine plate (movable platen 5).
  • a hardened plate is provided as a slide support.
  • the unlocking of the quick-release system 9 of the mold is extended, the movable platen 4 is about 10 cm moved / open and the ejector unit 7 before
  • the contour insert 11 extends with quills and after a second solidification time, the mold is opened. Unspecified upper and lower slide open and a not shown removal device can retract and grip the casting. Thereafter, the lateral slide not shown open and the removal device can remove the casting.
  • the contour insert 11 water jacket insert
  • the mold is sprayed in a conventional manner, the ejector unit 7 moves forward, the cylinder liners are inserted. The mold is closed, the release of the quick-release system 9 is retracted and the next shot can be made.
  • the movable contour insert 11 itself can also be removed and changed.
  • the unlocking of the quick release system 9 of the mold is first extended and then the ejector 7 before driven so that the movable platen 5 can ascend when the mold is closed. Then the whole slide can be removed and a new contour insert 11 installed.
