Abstract: A pressing plunger mechanism for a glassware forming machine has at least one pressing plunger which in normal operation can be moved axially in a reciprocating manner together with a pressing plunger receiver between an inoperative position and a pressing position. A piston rod of a piston is fastened to each pressing plunger receiver, which piston can be displaced in a cylinder of a pressing plunger holder. The pressing plunger holder can be moved axially in a reciprocating manner by a first drive and is connected in a non-rotatable manner to a threaded spindle. A nut which can be rotationally driven by the first drive is engaged with the threaded spindle and is coupled to a driven shaft of an angular gear. An input shaft of the angular gear can be rotationally driven by an electric servo motor of the first drive.

Abstract: The pressing plunger mechanism (1) has at least one pressing plunger (72) which in normal operation can be moved axially in a reciprocating manner together with a pressing plunger receiver (71) between an inoperative position and a pressing position. A piston rod (60; 61) of a piston (58; 59) is fastened to each pressing plunger receiver (71), which piston can be displaced in a cylinder (56; 57) of a pressing plunger holder (45; 46). A piston surface (74) facing away from the pressing plunger (72) is acted upon by a compressed fluid (83). The pressing plunger holder (45; 46) can be moved axially in a reciprocating manner by a first drive (9) and is connected in a non-rotatable manner to a threaded spindle (17). A nut (21) which can be rotationally driven by the first drive (9) is engaged with the threaded spindle (17) and is coupled (19) to a driven shaft (15) of an angular gear (14).

Abstract: A parison (12) is subjected to final blowing in a blow-mold (2) of a blow-molding station (1) to produce a finished glass container (19). The blow-mold (2) comprises blow-mold halves (3, 4) and a block mold (18) which is not divided longitudinally and which is encompassed by the blow-mold halves (3, 4) when the blow-mold (2) is closed. Compressed air (15) can be introduced by means of a blowing head (13) into the interior of the parison (12), until the finished glass container (19) has achieved its final form. In order to remove the glass container (19) from the blow-mold (2), it is grasped by its mouth (11) by means of a takeout mechanism. The blow-mold halves (3, 4) are then opened and the block mold (18) is moved downwards until it reaches a removal position.

Abstract: A parison is molded from a gob of molten glass by first increasing the volume of the interior of a cup-shaped main mold body by an extra volume. Then the molten-glass gob is inserted through an upper opening into the interior of the main mold body. A neck mold comprising a split neck ring is closed on the main mold body so that the neck mold and the main mold body together define a mold cavity partly formed by the interior of the main mold body. A plunger is inserted through the neck mold down into the gob in the mold cavity to displace molten glass and shape the gob into a parison. The extra volume of the interior of the main mold body is then decreased to zero at the latest until the time at which the parison is finished, so that the molten glass rises in the mold cavity up to a level above the top of the main mold body. Finally the parison thus formed is demolded.

Abstract: A distributing arrangement for a pressurized cooling fluid, especially air, for cooling a forming tool of a machine for forming thermoplastic material, especially molten glass, wherein the forming tool includes at least one split mold including mold segments which are respectively mounted on mold segment holders for movement therewith relative to one another and each of which is provided with a plurality of fluid channels for the flow of the pressurized of fluid channels for the flow of the pressurized cooling fluid therethrough, comprises a fluid distributing box including for each of the mold segments at least two branch channels individually communicating with at least one of the fluid channels when the distributing box is mounted on the mold segment holder.
