Definitions

  • the present invention relates to a molding flask mating mechanism for cast molding a slip under pressure and molding green articles of sanitary ware or the like, before being fired.
  • the sanitary ware represented by stool ware and wash basin is produced in such a manner that green articles are molded by cast molding a slip of muddy materials and then fired in a kiln.
  • the technique of cast molding the slip under pressure has hitherto been well known as disclosed in, for example, EP-A-352056, EP-A-389234, GB-A-792351, JP-A Sho 63-288705, JP-A Hei 3-69313, JP-A Hei 3-67604, JP-A Hei 3-69304, JP-A Hei 3-81103, JP-A Hei 3-67605, and JP-A Hei 3-83608.
  • a mating and positioning mechanism as shown in Figs. 11 and 12 has hitherto been used during the joining of the molding flasks with each other.
  • left and right molding flasks 3, 4 as well as upper and lower molding flasks 5, 7 composed of porous bodies and metallic capsules are provided with projecting knock pins 6, and knock pin bores 19 are bored in the positions at opposite molding flasks respectively, so that both the lateral molding flasks and the vertical ones are mated to be positioned.
  • the present invention aims at solving the above problem.
  • a molding flask transportation line 11 is disposed at the right side and a green article transportation line 12 at the left side.
  • Pressure cast producing apparatus are disposed at an intermediate portion between the molding flask transportation line 11 and the green article transportation line 12.
  • Each pressure cast producing apparatus comprises a pressurized machine casing 2.
  • a slip stand A for supplying a slip to the pressure cast producing apparatus is attached to each pressure cast producing apparatus.
  • the molding stations each comprise the pressurized machine casing 2 and slip stand A.
  • a casting mold transported on the casting mold transportation line 11 is transported to the molding station so as to be fixedly disposed from a casting mold branch line 32 which leads to the inside of the pressurized machine casing 2.
  • the molding flask transportation line 11b is divided into a molding flask transportation line 11a and a green article branch line 13, so that it is decided by discriminating the part number of molding flask whether the molding flask enters into a green article branch line 13 or directly passes the molding flask transportation line 11a to reach a molding flask housing line.
  • each pressurized machine casing 2 there is fixed a whole molding flask comprising left and right molding flasks 3, 4 as well as upper and lower ones 5, 7, the left and right molding flasks 3, 4 being urged by left and right urging cylinders 15, 16 and the upper and lower molding flasks 5, 7 being urged by upper and lower urging cylinders 14, 17.
  • the four molding flasks are urged from four directions to be one molding flask and thereafter the pressurized slip is charged therein so that the slip is deposited onto porous bodies at the inner surface of the molding flask.
  • the left and right molding flasks 3, 4 as well as upper and lower molding flasks 5, 7 are composed of porous bodies disposed inside the flask and metallic capsules cover the outside thereof.
  • a demolding work is carried out inside the pressurized machine casing 2 and a finished green article 1 is transferred to the green article transportation line 12 from the green article branch line 13.
  • a slip pressure-feeding pump At the slip stand A there are disposed a slip pressure-feeding pump, a slip temporarily storing tank and the like.
  • the molding flask transportation line 11 and the molding flask branch line 32 each have a smaller track width, so that, as shown in Figs. 1(a) and 1(b), the molding flask is put on and transported by a molding flask loading truck 30 having a smaller distance between the wheels.
  • a molding flask loading truck 30 having a smaller distance between the wheels.
  • the green article 1 is put on a green article loading truck 31 having a larger distance between the wheels travelling on the green article branch line 13 and green article transportation line 12 having a larger width of track.
  • Fig. 1(c) shows that the green article 1 after having been molded and demolded is put on the green article loading truck 31.
  • a casting mold is constructed based on the left and right molding flasks 3, 4 as well as upper and lower molding flasks 5, 7.
  • the entire molding flask is urged by the left and right urging cylinders 15, 16 for urging the left and right molding flasks 3, 4 and by the upper and lower urging cylinders 14, 17 for urging the upper and lower flasks 5, 7.
  • the four molding flasks of the pair of left and right molding flasks 3, 4 and the pair of upper and lower molding flasks 5, 7 each has therein a porous body and is covered at the outside thereof with a metallic capsule. At the edges on which the porous bodies contact each other in the four molding flasks there are provided long wedge-like shaped abutting portions 28, respectively.
  • all the long wedge-like shaped abutting portions 28 are adapted to come into close contact with each other.
  • the wedge-like shaped abutting portions 28 in the embodiment are made longer to be wedge-like shaped at all the rectangular edges. As shown in Fig. 4, the left and right molding flasks 3, 4 at first abut against each other through the wedge-like shaped abutting portions 28 as a guide and thereafter the upper and lower molding flasks 5, 7 are positioned vertically and mated by the portions 28 as a guide.
  • FIG. 6 a molding flask for constructing a green article 26 for a tank of porcelain, like a low tank, disposed at a flush stool.
  • the lower molding flask 23 and the upper molding flask 25 both are composed of inner porous bodies and metallic capsules covering them around, the green article 26 being deposited onto the inner porous bodies.
  • Wedge-like shaped abutting portions 9 project upwardly from the upper surface of the lower molding flask 23 and wedge-like shaped abutting portions 8 project downwardly from the lower surface of the upper molding flask 25, so that the upper molding flask 25 and the lower molding flask 23 are completely brought into close contact with each other at the position where both flasks are completely mated in the abutting state.
  • exchange type abutting surfaces 8a, 9a are disposed on the abutting surfaces of the wedge-like shaped abutting portion 8 attached to the upper molding flask 25 and of the wedge-like shaped abutting portion 9 attached to the lower molding flask 23, so that, when only the abutting surfaces 8a and 9a are worn, the portions 8 and 9 are exchangeable. Hence, even when the number of times of the use increases, the molding flasks engage with each other always with accuracy.
  • the wedge-like shaped abutting portions 8, 9 each are provided with two wedge-like surfaces, whereby the abutting portions 8 and 9 can be collectively disposed at one position.
  • Fig. 10 shows an embodiment for making the wedge-like shaped abutting portions 8 and 9 fine adjustable in position to each other, in which an adjusting bolt seat 18 and an adjusting bolt 20 are provided at a part of the porous body of the left and right molding flasks 3, 4 so that the wedge-like shaped abutting portion 9 can be fixed by a fixing bolt 21 to the left or right molding flasks 3, 4.
  • the fixing bolt 21 is unscrewed and the adjusting bolt 20 is rotated so that the wedge-like shaped abutting portion 9 can be adjusted into a predetermined position and again fixed by the fixing bolt 21.
  • the porous bodies composed of synthetic resin are disposed inside the four molding flasks and metallic capsules cover the outside thereof.
  • the wedge-like shaped abutting portions 28 are disposed at the entire surfaces of edges abutting against the porous bodies at the molding flask, so that, in the state where the wedge-like shaped abutting portions 28 abut against each other, the molding flasks are completely brought into close contact with each other.
  • the wedge-like shaped abutting portion 8 projects from the upper molding flask 25 and the lower wedge-like shaped abutting portion 9 projects from the lower molding flask 23, so that when both abutting portions 8, 9 abut against each other, the upper molding flask 25 and the lower one 23 are adapted to mate each other.
  • the present invention has the following advantage. Since the knock pins 6 have hitherto defined the mating position of the molding flask, a gap of allowance is required in the size of each knock pin 6 and knock pin bore 19, so that there is a risk of shifting the molding flasks relative to each other. Contrary to this, the wedge-like shaped abutting portions 8, 9 and the wedge-like shaped portions 28 according to the present invention clearly define and fix the positioning portions, whereby the disadvantage of the conventional technique is eliminated.
