Definitions

  • the present invention relates to a fixture for mounting a pattern plate in a moulding machine of the kind set forth in the preamble of claim 1
  • Figure 1 schematically shows a fixture consisting of a fixed guide pin and a swingably mounted guide pin in accordance with the invention
  • Figure 2 shows a schematic sectional view along the line II-II in Fig 1 .
  • Figure 3 schematically shows an alternative embodiment of the construction in Fig 1 , with an adjustable guide pin and a swingably mounted guide pin
  • the fixture for mounting a pattern plate 1 is intended to be used for providing a fixed, non-rotational mounting of the pattern plate 1 with its mainly planar surface 2 against a corresponding mounting surface 3 in the moulding machine
  • the pattern plate 1 comprises a pattern side (not shown) opposite the mainly planar surface 2
  • two guide pins 4 and 5 are mounted in the mounting surface 3 and corresponding bores 6 and 7 are positioned in the mainly planar surface 2 of the pattern plate 1 for engagement with the two guide pins 4 and 5
  • the guide pin 4 is fixed, and in order to accommodate tolerances in the distance a between the guide pins 4, 5 and the bores 6 (not shown), 7, one guide pin 5 is mounted on a pivotally mounted fitting 8 having a pivot axis 9 positioned at a distance b from the connection line 10 between the two guide pins 4 and 5 In this way the guide pin 5 is swingably mounted in such a way that the
  • the swingably mounted guide pin 5 extending further out from the planar surface 3 than the fixed guide pin 4, whereby the bore 7 of the pattern plate 1 can be brought into engagement with the guide pin 5 before the bore 6 is brought into engagement with the guide pin 4, providing a possibility of moving the pattern plate 1 in a direction along the line 10 connecting the two guide pins 4, 5, in order to bring the bore 6 into engagement with the fixed guide pin 4
  • the guide pins 4, 5 and/or the bores 6, 7 can be provided with a conical inlet formation, and the swingably mounted guide pin 5 may be elastically prestressed towards the neutral position, e g by means of a rubber bushing or a spring

Abstract

L'invention se rapporte à un dispositif de fixation pour le montage d'une plaque porte-modèles (1) dans un équipement de moulage produisant des moules au sable, dans lequel la plaque porte-modèles (1) opposée aux modèles présente une surface sensiblement plane (2) destinée au montage sur une surface de montage correspondante (3) de l'équipement de formation des moules. Ce dispositif de fixation comporte deux broches de guidage (4, 5) espacées l'une de l'autre (a) et des alésages correspondants (6, 7) ménagés dans et orientés perpendiculairement aux deux surfaces (2, 3) destinées à l'accouplement entre les broches de guidage (4, 5) et les alésages (6, 7) respectivement. En raison du montage d'une broche de guidage (5) sur un organe de fixation (8) monté pivotant, dont l'axe de pivotement (9) est situé à une distance (b) de la ligne (10) reliant les deux broches de guidage (4, 5), la tolérance de distance (a) entre les broches de guidage (4, 5) et les alésages (6, 7) peut être obtenue grâce au mouvement de pivotement de la broche de guidage (5).
