Definitions

  • the present invention relates to a device for blowing glass, said device comprising a casing and an inner mould piece that may be mounted inside the casing, the inner mould piece being equipped with an internal cavity.
  • Prior Art Blowing of glass may be effected in two principially different ways.
  • One way is blowing of glass in the manual way, where the blower in such a case from a crucible of melted glass metal with his blow pipe catches a gathering of melted glass, i.e. the blow pipe is rotated in the crucible of melted glass metal in order to make a suitable amount of glas metal to adhere to the blow pipe. Then the glass blower forms the final product, by blowing and by the use of suitable tools.
  • This way of glass blowing is thus a solid handicraft, i.e. the finished products are not exact copies of each other.
  • Another way of blowing glass is on a solid industrial basis, i.e. when producing a great number of products, e.g. bottles, at a low price.
  • the finished products are in principle exact copies of each other.
  • the manufacturing is usually effected via an assembly line, where blanks of melted glass at blowing stations are transferred into for instance bottles .
  • a primary object of the present invention is to present or device for glass blowing where the mould pieces of a cartridge in a simple way may be exchanged in order to vary the shape of the product effected by glass blowing.
  • a further object of the present invention is that the mould pieces mounted in the cartridge should be mutually fixed and fixed relative to the cartridge in a satisfying way regarding the glass blowing function.
  • Fig 1 shows a front view of a casing included in a mould cartridge according to the present invention
  • Fig 2 shows a top view of the mould cartridge according to Fig 1;
  • Fig 3 shows a side view of the mould cartridge according to

  • Fig 8 shows a perspective view of the mould cartridge, with the adherent first inner mould pieces, according to the present invention, where a lump of liquid glass metal, with the adherent blow pipe, is to be inserted into the mould cartridge
  • Fig 9 shows a perspective view of the mould cartridge according to Fig 8, a finished blown product being present in the mould cartridge
  • Fig 10 shows a perspective view of the mould cartridge according to Fig 8, the principles of removing the finished blown product being shown
  • Fig 11 shows a perspective view of the pieces of an alternative second inner mould piece that is intended to be mounted inside a casing for creating a mould cartridge according to the present invention
  • Fig 12 shows the second alternative inner mould piece in assembled condition
  • Fig 13 shows a perspective view of an alternative embodiment of the casing of the mould cartridge according to the present invention, the side walls of the casing being in active position;
  • Fig 14 shows a side view of the casing according to Fig 13;
  • Fig 15 shows a perspective view of the casing according to Fig 13 where the side walls have been removed from each other;
  • Fig 16 shows a side view of the casing according to Fig 15.
  • a casing 1 is shown, said casing 1 being part of the mould cartridge that constitutes an essential part of the present invention.
  • the casing 1 comprises a first side wall 3 and a second side wall 5, said side walls 3, 5 being attached to a base 7 that also is a part of the casing 1.
  • the first side wall 3 is pivotally attached to the base 7 via hinges 9, said hinges 9 preferably being adjustably attached (not shown) to the base 7.
  • This arrangement gives the benefit that the distance of the first side wall 3 to the second stationary side wall 5 may be adjusted to some extent.
  • both side walls 3 and 5 are parallel to each other.
  • the side walls 3, 5 and the base 7 are preferably manufactured from cast iron or graphite depending on which surface structure the finished product should have.
  • the first side wall is equipped with a lever 10 that in the shown embodiment is attached to one end of the first side wall 3 and extends vertically when the first side wall 3 is in the position shown in Fig 1-3.
  • first side wall 3 is equipped with first guiding pins 11, in the shown embodiment two guiding pins 11, that are located at the top of the first side wall 3.
  • FIG 4-6 an inner mould piece 12 is shown, said mould piece 12 likewise being part of the mould cartridge according to the present invention.
  • said inner mould piece 12 constitutes a first sub-piece 13A, a second sub-piece 13B and a third sub-piece 14, the first and second sub-pieces 13A and 13B being located on top of the third sub- piece 14.

  • the upper first and second sub-pieces 13A and 13B are also equipped with guiding sleeves 16, in the shown embodiment four guiding sleeves 16, that are located in the upper part of the longitudinal side surfaces of the first and second sub- pieces 13A and 13B. In Fig 4 only two guiding sleeves 16 are visible since two further guiding sleeves are located on the opposite side of the first and second sub-pieces 13A and 13B. Said guiding sleeves 16 are intended to cooperate with the first guiding pins 11 on the side walls 3 and 5.
  • the first and second sub-pieces 13A and 13B are equipped with lifting rods 17 that are used to rise the first and second sub-pieces 13A and 13B from the blown product, see below.
  • the first, second and third sub-pieces 13A, 13B and 14 of the inner mould piece 12 have been given such a design that when said sub-pieces 13A. 13B and 14 are assembled to an inner mould piece 12, see Fig 4, a cavity 18 is created in the central area of the inner mould piece 12. As will be evident from the description below said cavity 18 defines the space, in which the blown product is created.
  • the sub-pieces 13A, 13B and 14, forming part of the inner mould piece 12, are preferably manufactured from wood, e.g. alder or beech. These sub-pieces 13A, 13B and 14, manufactured from wood, are soaked with water before they are mounted in the casing 1.
  • Fig 7 it is shown how the inner mould piece 12, in assembled condition, is to be mounted in the casing 1, the first side wall 3 of the casing 1 in this face being folded aside by rotation around the rotating axis that is defined by the hinge 9.
