A mold opening and closing mechanism for an I.S. machine having a plurality of individual sections each having a section frame having a top wall. A pair of mold support mechanisms are supported above the top wall of the section frame for linear displacement and displaced by a motor having, a rotary output, secured to the top wall, via a rotary to linear transmission supported above the top wall of the section frame horizontally adjacent the mold support mechanisms.

Mold opening and closing mechanism for an I.S. machine

An I.S. machine has a plurality of individual sections arranged in side by side relation. Each section has a blank station for forming a parison from a gob of molten glass, and a blow station for forming a parison into a bottle. An invert and neck ring holder mechanism is located between these stations for transferring a parison between from one station to the other. Each station has a mold opening and closing mechanism which has a pair of opposed mold support mechanisms supported for linear displacement between a retracted position and an advanced position. Each mold support mechanism is supported by a first shaft on one side of the center of the mold opening and closing mechanism, proximate the invert and neck ring holder mechanism, extending perpendicularly to the engagement plane, and by a second shaft on the other side of the center of the mold opening and closing mechanism, remote from the invert and neck ring holder mechanism, extending perpendicularly to the engagement plane. The second shaft is second interconnected with the mold support mechanism enabling relative motion between the mold support mechanism and the second shaft in the parison transfer direction so that expansion of the mold support mechanism will take place in the transfer direction away from the invert and neck ring holder mechanism.

A mold opening and closing mechanism for an I.S. machine including a pair of mold support mechanisms supported for displacement between a retracted position and an advanced position where they will engage. A mold support mechanism is displaced by a transmission including a lead screw which is supported by a housing, left hand and right hand nuts operatively associated with the lead screw, and links interconnecting the left hand and right hand nuts and the mold support mechanism. The housing has a rear wall defining a flat surface, and the left hand and right hand nuts have a flat rear bearing surface, the rear wall flat surface and each of the bearing surfaces has a selected spacing therebetween when the mold support mechanism is at the retracted position, and the lead screw has a rigidity selectively chosen so that when the mold support mechanism is displaced to the advanced position into engagement with the other mold support mechanism, with a predetermined force, the lead screw will deflect to establish engagement between the bearing surfaces and the rear wall flat surface, whereby the mold support mechanism will be positively maintained at the advanced position. A motor coupled to the lead screw drives the transmission.

Mold opening and closing mechanism for an I S machine

A takeout mechanism for a section of a I.S. machine which will grip the finish of one or more bottles at a blow station and carry the gripped bottles away from the blow station and deposit them on a deadplate. The bottom of the bottles can be a vertical distance from the finish within a selected distance range. A Z-axis offset is defined for the bottles and an X-Z profile is defined for the Z-axis offset to control their displacement from the blow station to the deadplate.

Takeout mechanism for an I.S. machine

A mold opening and closing mechanism for an I.S. machine which has a pair of mold support mechanisms supported for horizontal displacement between a retracted position and an advanced position. These support mechanisms are linearly displaced by a drive assembly which includes a lead screw, a housing secured to the section frame for supporting the lead screw, a motor coupled to the lead screw, nuts operatively associated with the lead screw, and links interconnecting the nuts with their associated mold support mechanism. The housing has a rear wall defining a flat surface, and the nuts have flat rear bearing surfaces with a selected spacing therebetween when the mold support mechanism is fully retracted. The lead screw has a rigidity selectively chosen so that when the mold mechanism is displaced to the advanced position into engagement with the other mold support mechanism, with a predetermined force, the lead screw will deflect to establish engagement between the flat bearing surfaces and the rear flat wall surface of the housing which is secured to the frame, whereby the mold support mechanism will be part of a continuous solid structure extending from the section frame, up the housing of each of the drive assemblies, across the nuts and the links of each drive assemblies, and across mold support mechanisms thereby positively preventing the vertical or horizontal displacement of the engaged mold support mechanisms from forces applied thereto.

Mold opening and closing mechanism for an I. S. machine

A mold opening and closing mechanism for an I.S. machine having a plurality of individual sections. A pair of opposed mold holding mechanisms is supported on top of the section frame for linear displacement between a separated retracted position whereat each mold support mechanism is located at a start position and an advanced position whereat molds held by the mold support mechanisms will forcefully engage. A mold holding mechanism is secured to the free ends of a pair of round shafts which are slidably supported within horizontally separated bearings in a housing supported on the section frame and extending vertically upwardly.

An I.S. machine is disclosed which has a plurality of individual sections arranged in side by side relation. Each section has blank mold and blow mold opening and closing mechanisms and an invert and neck ring holder mechanism for transferring a parison between these mechanisms. Each of the mold opening and closing mechanisms has a pair of opposed mold support mechanisms which are supported for linear displacement. Ways at either end of the section support one end of each pair of mold support mechanisms and the other end is supported on a pair of shafts located between the mechanisms. One of these shafts is supported between the spaced vertical supports of the invert and neck ring holder mechanism and the other shaft has a first part supported between one of the spaced vertical supports and the vertical invert housing and a second part is supported between the other one of the spaced vertical supports and the vertical invert housing.
