Definitions

  • the invention relates to a vibratory mold consisting of a Use with one or more mold nests for admission of pourable masses, especially concrete for production of shaped stones, being used on a vibrating table the molding machine arranged and with a vertical movable mold frame of the molding machine is connected, and the inside of the mold frame and the outside of the Inserted projections and recesses for receiving Have damping means between the mold frame and insert.
  • DE-A-27 10 643 is a device for attachment shapes exposed to vibrations on a machine table a concrete block molding machine known.
  • the machine table has a mold frame in which the mold is let in. It is between the outer walls Form and the inner walls of the mold frame an elastic Arranged arranged that surrounds the shape on all sides and to Reduction of the noise immissions that is used by the Vibrations of the mold are caused.
  • the elastic The strip has protrusions and depressions on the inside on that with corresponding recesses and protrusions interact on the outer walls of the mold.
  • the Form frames are provided with externally actuated set screws, those with clamping rails on the inner walls of the mold frame are connected. With the help of the clamping rails, which in corresponding depressions on the outer sides of the elastic The mold can engage with the mold using the mold frame or the machine table.
  • a disadvantage of this known embodiment is that as a result of vibrations and vibrations that affect the shape act on the elastic bar in very high shear forces is exposed to the vertical direction. The consequence of this are premature signs of fatigue of the elastic material, that break and destroy the elastic Guide the bar. In addition, arise with every work cycle changing shear forces in one direction when Lowering and tensioning the mold insert on the board of the Vibrating table and in the other direction when lifting the Mold frame due to the weight of the mold insert. Thereby there is considerable relative movement between the mold frame and mold insert, which adversely affects the centering and fix the shape.
  • the invention is based on the object To avoid disadvantages and a permanent and wear-resistant Vibration damping between egg insert and mold frame to ensure.
  • the object is achieved in that the protrusions of the insert into the recesses of the Engage mold frame, or vice versa, and that the damping means between the facing surfaces of the Projections and the depressions are arranged.
  • a vibrating table 1 of a molding machine 2 On a vibrating table 1 of a molding machine 2 is a Insert 3 with mold nests 4 placed. Between the vibrating table 1 and insert 3 is a board 5 in a known manner inserted.
  • the rectangular insert 3, the Long side is shown in Fig. 1, with a the molding machine 2 connected mold frame 6 held, about side brackets 7 vertical in the molding machine 2 are moveable and drivable, the mold frame 6 with the insert 3 moved up and down or on the vibrating table 1 are discontinued.
  • Above the vibrating table 1 a die 8 of the molding machine 2 with several Mold plates 4 assigned printing plates 9 in the usual way arranged vertically movable.
  • the mold frame 6 consists of two longitudinal and two transverse parts, which are screwed together or are welded.
  • this also has insert 3 consisting of two longitudinal and two transverse parts its two shorter transverse sides have a triangular shape Projection 10 on, which is without interruption on the entire length of the insert 3 extends and into one corresponding recess 11 on the inner transverse sides of the Form frame 6 engages.
  • the recess 11 is also triangular in shape with inwardly diverging sides and also extends without interruption the two inner transverse sides of the rectangular shape frame 6, which only on its transverse sides via the brackets 7 is connected to the molding machine 2.
  • a damping plate 12 or 13 is inserted into the underside, which extends over the entire length of the two transverse sides extend.
  • a recess 14 on the underside of the mold frame 6 provided for a pressure piece 15, which with screws 16 the mold frame 6 is screwed (Fig. 3). In doing so the damping plates 12 and 13 via the pressure piece 15, the with a beveled surface 17 on the lower damping plate 13 presses between mold frame 6 and insert 3 clamped.
  • the beveled surface 17 of the pressure piece 15 forms together with the upper, also beveled Inner surface of the mold frame 6, the triangular depression 11, in which the damping plates 12 and 13 are inserted are.
  • the bracing using the pressure pieces 15 ensures for proper mounting of the damping plates 12, 13 while ensuring a firm, detachable connection between mold frame 6 and insert 3.
  • To the top Cover of the mold frame 6 and the damping plate 12 is a wear plate 18 on the top of the mold frame 6 screwed on.
  • the lower part of the tab 10 and the recess 11 is vertical by one extending surface 20 is formed, which to the Connect sloping surfaces 19.
  • the attachment by means of Thrust pieces 15 and screws 16 can be on the two long sides omitted. This can result in material and manufacturing costs be saved. By unscrewing the Pressure pieces 15 on the transverse sides of the mold frame 6 can Insert 3 removed from the mold frame 6 downwards become.
  • the damping plates 12 and 13 can be made of rubber or Plastic or some other elastic material. Instead of the damping plates 12 and 13 can also other damping means, for example springs used be detachable or fixed to the insert 3 and / or on Form frame 6 are attached or clamped.
  • the pressure pieces 15 for clamping the damping plates 12, 13 may be provided.
  • the triangular depression 11 also in the insides of the Form frame 6 may be incorporated.
  • the Form frame 6 for receiving the insert 3 by screw connections be solvable.
  • the triangular cross section of the projection 10 and the recess 11 can also have other geometric Cross-sectional shapes such as rectangular, semicircular and other clamping cross-sections can be used.
  • Essential is that the cross-sections are two or more sides have the force applied by the vibrator drive or in the event of force by starting the Form (stripping the concrete part) the resulting forces from insert to the mold frame and inversely in the X, Y and can transmit the Z direction.
