Definitions

  • This invention relates to an installation for casting from ceramic material in slip form articles of sanitaryware, in which a plurality of mould units are arranged in a generally horizontal line on a support structure. Casting in such installations is known as battery or bank casting.
  • moulds for casting cistern tanks are made of two parts which, relative to the upright position of a cistern tank, comprise a container part which shapes the exterior of the side walls and bottom wall of the cistern tank, and a top part which closes the mould cavity, the two parts being separable at a horizontal parting plane by relative movement in a vertical direction.
  • the cast piece is removed from the container part by movement in a vertical direction unless the mould is turned.
  • the top part may have a core which projects down into the container part, for solid casting of a cistern tank, or the top part may simply be a closure member and the container part may include cistern tank.
  • moulds for casting cistern tanks are adapted for use on a horizontal line by dividing the mould vertically into two side parts.
  • an installation for casting from ceramic material in slir form articles of sanitaryware having a plurality of mould units arranged in a generally horizontal line on a support structure, in which each mould unit comprises two side mould parts which can be assembled to define a casting cavity for casting a cistern tank for a water closet suite, one side mould part having a substantially vertical cavity surface for forming the back wall of the cistern tank and the other side part being substantially channel-shaped in plan and having substantially vertical cavity surfaces for forming the side walls and front wall of the cistern tank, one of the side parts having an integral base for forming the bottom wall of the cistern tank, the side mould parts being adapted to be opened and closed by relative movement in a direction longitudinally of the line of mould units, each side mould part being connected in back-to-back relation to the adjacent side mould part of the next adjacent mould unit in the line.
  • the base for forming the bottom wall of the cistern tank is preferably provided on the side mould part having the vertical cavity surface for forming the back wall of the tank, and there is also provided a core part which is adapted to be moved in a vertical direction into the side parts or so as to be spaced above them.
  • the base for forming the bottom wall of the cistern tank is preferably provided on the side mould part which is channel-shaped in plan, and either a separate mould cover part is provided or the other side mould part has an integral cover part.
  • Figures 1 to 3 show an embodiment for solid casting of cistern tanks in a line or bank of fifty or more mould units arranged in a horizontal line on a support structure in the form of two rails 7 extending longitudinally of the line.
  • Each mould unit 1 consists of three main mould parts: two side parts 2 and 3 and a core part 4.
  • the side parts 2 and 3 are supported on carriers 8 fitted with rollers 9 so that they can be moved easily on the rails 7 in a longitudinal direction of the line.
  • the side parts 2 each comprise an upstanding part 11 having a surface 12 which shapes the external surface of the back wall of the tank and a base part 13 which forms the bottom of the tank.
  • the side parts 3 each comprise upstanding mould walls 15, 16 and 17 which form a channel shape as viewed in plan, the inside faces of which form the external surfaces of the side and front walls of the tank.
  • Each pair of side parts 2 and 3 of the same mould unit 1 can be brought together to define the casting cavity, the lower side edges 18 and 19 being inclined to the horizontal to allow the parts to be separated directly by movement in a horizontal direction without the mould parts scraping against each other.
  • each side part 2 is connected rigidly in back-to-back relation with the side part 3 of the next adjacent mould unit in the line.
  • the core part 4 for each mould unit comprises a core 20 depending from a rim 21 which when the mould unit is assembled rests on the upper edges of the side parts 2 and 3 which lie in a common plane.
  • the core part 4 is adapted to be lifted vertically above the line during emptying or lowered so that the core 20 is located between the side parts 2 and 3 in the assembled condition of each mould unit.
  • the mould units 1 of the entire line are assembled by closing up the side parts 2 and 3 and lowering the core parts 4.
  • the line of mould units 1 is then clamped longitudinally by an overall clamping arrangement at each end of the line.
  • the core parts 4 may be held by clamping or other hold-down means, which may be common to all the mould units, or the core parts 4 may be sufficiently heavy simply to rest on the side parts 2 and 3 without risk of the core moving when the mould unit is filled with slip under pressure.
  • mould unitsl are then filled with slip, the slip flowing from a slip supply tank under gravity into the casting cavity in each mould unit 1.
  • the emptying procedure is as follows.
  • the core part 4 of the first mould unit of the line is lifted by a suitable lifting means which is capable of traversing the entire line of mould units.
  • the overall clamping of the side parts is then released and dealing with each mould unit in turn, the side parts are separated by moving side part 3 away from sidepart 2 on which the tank rests on the base part 13.
  • the tank 26 (see Figure 3) is then removed using suitable tongs or similar tools and placed on a rack at one side.
  • the emptied side part 2 is then pulled along the track which movement simultaneously pulls the side part 3 of the next mould unit to open that mould unit.
  • Figure 4 shows a mould unit for drain casting of cistern tanks. Only one mould unit is shown but a plurality of such mould units will be provided in a line, each side mould part being joined in back-to-back relation with the adjacent side mould part of the next mould unit, as for the example of Figures 1 to 3.
  • the mould unit comprise a first side mould part 40 having a substantially vertical cavity surface 41 for forming the back wall of the tank and an integral top wall for closing the top of the tank casting cavity, and a second side mould part 45 which is substantially channel-shaped in plan having substantially vertical cavity surfaces 46, 47 and 48 for forming the side walls and the front wall of the tank and an integral base 49 for forming the bottom wall of the tank.
  • the mould units are assembled and the cavities filled with slip under pressure. After allowing the appropriate casting time to elapse, a lower aperture 5 provided in the base 49 of each mould is opened and the surplus slip from the inside of the tank will drain out leaving the green drain-cast tanks in the moulds.
  • the mould units are then opened, in turn, by horizontal movement of the side parts along the line and each tank is removed from the respective mould part 45 and put to one side, this operation being repeated along the complete line of moulds.
