Definitions

  • the invention relates to a linear opening and closing mechanism of moulds of a container glass machine comprising a frame on which two mould holders are mounted against each other in a linearly sliding manner while the mould holders are interconnected with a drive.
  • a gob of molten glass in a mouldable condition is introduced to the moulding (or forming) cavity of the blank mould from the top. It is subsequently compressed by the plunger mechanism by being forced into the shaping cavity for formation of the semi-finished glass product called parison while the shape of the inner surface of the parison is determined by the shape of the outer surface of the plunger head and the shape of the outer surface of the parison is determined by the inner shape of the blank mould cavity.
  • the mechanism of linear opening and closing of the moulds for the blank mould opens and the produced parison is removed from the blank mould and transferred by the Invert mechanism to the open mechanism of linear open and closing of moulds for the blow moulds.
  • the mechanism of linear open and closing of moulds for the blow mould closes and shaping of the final form follows. After the completion of the final moulding the linear opening and closing mechanism of the moulds for the blow mould opens and the finished product is removed from the area of the linear mould open and closing mechanism by the Take-Out mechanism to the dead plate. In one working cycle the container glass machine processes one or more gobs of molten glass at the same time.
  • Patent no. US 6318129 describes a design of a linear mould opening and closing mechanism by means of an elevating screw on which two nuts move from or towards each other depending on the turning direction and the movement of the nuts causes the mould holders to move.
  • a disadvantage is the limiting critical speed of the elevating screw and consequently relatively slow opening and closing of the moulds.
  • Another disadvantage is relatively quick wear of the bearings.
  • Patent no. US 4009018 deals with a linear mould opening and closing mechanism using a crank mechanism with a connecting rod
  • patent no. US 5578105 describes a similar mechanism using a crank mechanism with a connecting rod with a transversal "T" guide.
  • a disadvantage of linear opening and closing of moulds with the use of a crank mechanism with a connecting rod is a high number of mechanical components resulting in addition of production inaccuracies and partial rigidities that have a negative impact on the overall rigidity. With regard to unilateral mounting such a design is sensitive to additional forces that may cause undesired deformations. Another disadvantage is relatively quick wear of the bearings.
  • linear mould opening and closing mechanism naturally refers to a mechanism that does not only close moulds, but opens them as well.
  • each mould holder a separate drive is installed that carries an eccentric.
  • the eccentric comprises a disk mounted on the output shaft of the drive while an eccentrically mounted pin protrudes from the disk and reaches into a groove in the mould holder.
  • the eccentric comprises a crank with an eccentrically located pin.
  • the mould holders are mounted in a sliding way in guides arranged on the frame as well as on a rod that is firmly fixed to the frame.
  • the drive may comprise of an electric motor with a gearbox installed on it.
  • Fig. 1 shows the linear opening and closing mechanism of moulds of a container glass machine in a spatial view, including the moulds.
  • Fig. 2 presents the linear opening and closing mechanism of moulds of a container glass machine in a partial cross- section without the inserts of the moulds and without the moulds, illustrating the sliding mounting of the pin in the mould holder.
  • Fig. 3 shows the linear opening and closing mechanism of moulds of a container glass machine in the ground plan in the open position without the inserts of the moulds and without the moulds.
  • Fig. 1 shows the linear opening and closing mechanism of moulds of a container glass machine in a spatial view, including the moulds.
  • Fig. 2 presents the linear opening and closing mechanism of moulds of a container glass machine in a partial cross- section without the inserts of the moulds and without the moulds, illustrating the sliding mounting of the pin in the mould holder.

  • Fig. 4 shows the linear opening and closing mechanism of moulds of a container glass machine in the ground plan in the closed position without the inserts of the moulds and without the moulds.
  • Fig. 5 presents a kinematic diagram of a half of the linear opening and closing mechanism of moulds of a container glass machine.
  • Fig. 6 illustrates the eccentric as a disk with an eccentrically located pin.
  • Fig. 7 shows the eccentric as a crank with an eccentrically located pin.
  • the linear opening and closing mechanism 1 of moulds 14 of a container glass machine in particular a double-GOB machine (see fig. 1 , 2, 3 and 4) comprises a frame 11 on which two holders 4 of the moulds 14 are mounted against each other in a linearly sliding manner.
  • the holders 4 of the moulds 14 are mounted in a sliding way in a guide 6 with the shape of a groove, firmly attached to the frame 11 , and also on a rod 3, firmly fixed to the frame 11 via an arm 2.
  • the rod 3 has a circular or another suitable geometrical cross-section.
  • Each of the holders 4 of the moulds 14 is interconnected with the corresponding drive 9 via an eccentric 7, which comprises a disk mounted on the output shaft of the drive 9, while from the disk an eccentrically mounted pin 8 protrudes into the groove 13 in the bottom part of the holder 4 of the mould 14.
  • an eccentric 7 is mounted on the pin 8 in a rotary way. A detail of such an eccentric 7 is shown in fig. 6.
  • the linear opening and closing mechanism 1 of moulds 14 of a container glass machine works as follows:
  • the eccentrics 7 have the opposite rotation direction and when it is necessary to close the moulds 14 the eccentrics 7 turn to the required position and the rotational movement of the eccentrics 7 is transformed to the linear sliding movement of the holders 4 of the moulds 14 by the movement of the pins 8 in the grooves 13, causing the holders 4 of the moulds 14 to slide in the guide 6 and on the rod 3. This way the moulds 14 are closed (see fig. 4).
  • the eccentrics 7 turn back causing retraction of the holders 4 of the moulds 14 and opening of the moulds 14 (see fig. 3).
  • the linear opening and closing mechanism 1 of moulds 14 of a container glass machine is principally the same for the blank mould as well as the blow mould, which is not shown here.
  • Moulds 14 with a different suspension can be replaced in the holder 4 of the moulds 14 by unscrewing one nut 15.
