Definitions

  • the invention relates to a vibrating mold, according to the preamble of patent claim 1.
  • a device for fixing vibration-exposed molds to a machine table is more commonly known as a concrete block forming machine.
  • the machine table has a mold frame, in which the shape is embedded.
  • an elastic strip is disposed between the outer walls of the mold and the inner walls of the mold frame, which surrounds the mold on all sides and serves to reduce the noise emissions caused by the shaking movements of the mold.
  • the elastic strip has on its inner side projections and depressions which cooperate with corresponding recesses and projections on the outer walls of the mold.
  • On the mold frame operable adjusting screws are provided, which are connected to clamping rails on the inner walls of the mold frame. With the help of the clamping rails, which engage in corresponding recesses on the outer sides of the elastic strip, the shape of the mold frame or the machine table can be clamped.
  • a disadvantage of this known design is that due to the vibrations and shaking movements, which act on the mold, the elastic strip is exposed to very high shear forces in the vertical direction. The consequence of this is premature fatigue of the elastic material leading to breakage and destruction of the elastic band.
  • changing shearing forces also occur at each stroke, in one direction when lowering and tensioning the set of formulas on the board of the shaker table and in the other direction when lifting the frame due to the weight of the formula set. This results in considerable relative movements between the mold frame and formula set, which adversely affect the centering and fixing of the mold.
  • the invention has for its object to avoid the disadvantages mentioned and to ensure a durable and wear-resistant vibration damping between Eimsatz and mold frame.
  • the damping means which are arranged between the mutually facing surfaces of the projections and depressions, claimed only to pressure.
  • the insert is positively connected to the mold frame. This results in a particularly effective, durable and wear-resistant vibration damping between insert and mold frame.
  • the positive connection also allows only small vertical relative movements between the insert and the mold frame, since the damping plates have a large contact surface. This leads to a small surface pressure and thus to a small spring travel.
  • the rectangular executed insert 3 whose longitudinal side is shown in Fig. 1, is of a mold frame 2 connected to the molding machine 6 held.
  • the lateral brackets 7, which are mounted vertically movable and driven in the molding machine 2 the mold frame 6 can be moved up and down with the insert 3 and placed on the vibrating table 1.
  • Above the vibrating table 1 is a forming die 8 of the molding machine 2 with a plurality of the mold cavities 4 associated printing plates 9 arranged vertically movable in the usual way.
  • the mold frame 8 consists of two longitudinal and two transverse parts which are screwed or welded together.
  • the insert 3 which also consists of two longitudinal and two transverse parts, has on its two shorter transverse sides a Dreleck-shaped projection 10 which extends over the entire transverse side length of the insert 3 without interruption and into a corresponding one Recess 11 engages the inner transverse sides of the mold frame 6.
  • the recess 11 is also dreleckförmig formed with inwardly diverging sides and also extends without interruption on the two inner transverse sides of the rectangular mold frame 6, which is connected only at its transverse sides on the brackets 7 with the molding machine 2.
  • a damping plate 12 and 13 is inserted at the top and at the bottom, which extend over the entire length of the two transverse sides.
  • a recess 14 for a pressure piece 15 is provided on the underside of the mold frame 6, which is screwed with screws 16 to the mold frame 6 (Fig. 3).
  • the damping plates 12 and 13 are clamped by means of the pressure piece 15, which presses with a chamfered surface 17 on the lower damping plate 13, between the mold frame 6 and insert 3.
  • 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 recess 11, in which the damping plates 12 and 13 are inserted.
  • the bracing by means of the plungers 15 ensures proper retention of the damping plates 12, 13 and at the same time ensures a firm, detachable connection between the 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 top of the Molded frame 6 screwed.
  • the damping plates 12 and 13 may be made of rubber or plastic or other elastic material. Instead of the damping plates 12 and 13 and other damping means, such as springs can be used, which are releasably or test attached to the insert 3 and / or the mold frame 6 or clamped.
  • the triangular projection 10 and the triangular recess 11 can extend on both the lateral sides and on the longitudinal sides of the insert 3 and the mold frame 6 over its entire circumference without interruption.
  • the pressure pieces 15 for clamping the damping plates 12, 13 may be provided on all sides of the mold frame 6.
  • the triangular recess 11 may also be incorporated into the inner sides of the mold frame 6. In this case, the mold frame 6 for receiving the insert 3 by screw connections must be solvable.
