Definitions

  • the invention concerns those machines used in the forming of sanitary articles, in particular water closet pans of wall-mounted type.
  • Sanitary articles are formed by casting slip in hygroscopic and/or permeable moulds, which can comprise two or more parts depending on the complexity of the article to be formed.
  • Resin moulds have much better mechanical characteristics than plaster moulds, with the result that improved casting techniques have enabled the slip to be fed generally at a pressure of between 3 and 15 bar.
  • moulds composed of two parts to form articles of simple configuration such as wash basins or pillars
  • machines or so-called casting lines are known in which the mould parts comprising a female part and a male part are mounted in line and mutually slidable.
  • these moulds are formed of at least three parts, at least one of which is brought into contact with the others in a direction perpendicular to that in which these latter are brought into mutual contact.
  • Casting lines are in fact known comprising a number of individual moulds arranged side by side in parallel.
  • Machines for series-casting wall-mounted pans are also known using moulds in four parts which open and close in three mutually perpendicular directions.
  • the closure forces between the mould parts can be compensated only partly, namely only in one direction.
  • the object of this patent is to enable a forming line for sanitary articles, in particular wall-mounted water closet pans, to be implemented with moulds comprising at least three parts in which the mould closure forces are compensated along the line, to allow light and economical line construction, practically without limit on the number of articles formed simultaneously by it.
  • the line is arranged to receive moulds comprising at least three parts.
  • moulds comprising two parts, plus a third part which is brought into contact with the other two in a direction perpendicular to that in which these latter are brought into mutual contact.
  • the object of the invention is attained in that during casting, the third mould part is securely fixed to the other two by suitable means, such that the closure forces which arise in a direction perpendicular to the line direction are absorbed in each individual mould, whereas the closure forces in the line direction are compensated for all the intermediate moulds.
  • the mould 12 is composed of three parts, indicated by the reference numerals 120, 121, 122 respectively, of which two parts, namely the parts 120 and 121, come into mutual contact in the axial direction of the casting line, the third part 122 coming into contact with the other two in a direction perpendicular thereto.
  • the part 120 is intended to form the lower part of the wall-mounted pan, the part 121 is intended to form the upper part or rim, and the part 122 is intended to form the lower stench trap and the pan rear to be fixed to the wall.
  • the mould 12 is arranged to form two wall-mounted pans, but can be structured to enable a different number of wall-mounted pans to be formed simultaneously, depending on the line production requirements.
  • a movable core 110 manually inserted as described hereinafter, cooperates with the part 121.
  • Figures 1 and 2 show the machine 1 of the invention, comprising two opposing endpieces 2 and 3 upperly supporting, in a central position, a beam 4 of I cross-section. At its ends the beam 4 comprises a flange 5 for fixing to the endpieces 2 and 3 by usual means, such as bolts or the like.
  • the two endpieces 2 and 3 are also connected together by four identical tie rods 6, 7, 8, 9, arranged in two parallel rows, as shown in Figure 2.
  • the beam 4 is arranged to slidingly support mould blocks each composed of one of the said parts 120 carrying on its rear, ie in the opposite position to that shown in Figure 3, one of the said parts 121.
  • Each block 10 is contained within a lowerly open perimetral reinforcement frame, which can be either a single structure or comprise a pair of upperly open frames 100 and 101 respectively.
  • the frames 100 and 101 are suspended from the beam 4 slidingly via wheels 11 which enable them to traverse in the direction of the longitudinal axis of the beam 4.
  • the third mould part 122 is coupled to a platform composed of three lower beams 105, 106, 107 welded together and arranged to lock onto the frames 100 and 101 when the mould is closed.
  • the beams 105, 106, 107 form a single unit and are suspended from the frames 100 and 101 by two identical cylinder-piston units 103 arranged to move these beams together with the respective mould part 122 into a lowered open position distant from the parts 120 and 121, shown to the right of Figure 2, and into a raised closed position, shown to the left of Figure 2.
  • suitable adjustable supports 102 cooperate with the cylinder-piston units 103 to lock the beams 105, 106, 107 to the frames 100, 101 to close them in such a manner as to prevent their opening when subjected to the pressure of the slip.
  • the endpiece 2 carries a mould part 121 aligned with the suspended mould parts, a large cylinder-piston unit 108 provided with a thrust head 109 being fixed to the endpiece 3 to slide the suspended blocks 10 and press them against that mould part 121 suspended from the endpiece 2.
  • the movable core 110 is inserted manually above the mould part 121 to form the stench trap of said water closet pan.
  • the invention operates in the following manner.
  • Said first block 10 is then moved manually against that mould part 121 fixed to the endpiece 2, after inserting the movable core 110.
  • the articles are removed from the moulds by operating in the reverse sense, the formed articles being extracted from the mould part 120 either individually or in pairs, by appropriate usual extractor devices after removing the core 110.
  • the blocks 10 will lie all bunched against the thrust head 109 of the cylinder-piston unit 108, which has already been retracted to lie close to the endpiece 3 of the line.
  • the machine structure can comprise four beams, namely two lower and two upper, for the said purpose of guiding and supporting the blocks 10.
  • Mould opening and closure can also be mechanized.
  • the core 110 could be handled mechanically or be made formed integral with the mould piece 121.
