A locking finger for a unit having a molding cavity for molding the container delimited at least by a first shell attached to a first mold carrier and by a second shell attached to a second mold carrier that is movable relative to the first mold carrier between an open position and a closed position, the first mold carrier comprising a control member for controlling the locking finger and the second mold carrier comprising a locking opening, the locking finger comprising an interface for mechanical coupling to the control member, and a locking portion designed to cooperate with the locking opening in the closed position. The molding unit is a subassembly of a plurality of mechanical parts assembled together rigidly, including a main body of the finger comprising the mechanical coupling interface, and said locking portion, which is a main sleeve made from anti-friction material assembled on the main body.

Locking finger for a unit for molding containers made from thermoplastic material

A locking finger for a molding unit, the molding unit comprising a cavity for molding the container that is at least defined by a first shell fixed on a first mold holder and by a second shell fixed on a second mold holder that can move relative to the first mold holder between an open position and a closed position, the first mold holder comprising a component for controlling the locking finger and the second mold holder comprising a locking opening, the locking finger including an interface for mechanically coupling to the control component, and a locking portion designed to engage with the locking opening in the closed position. The locking portion comprises an anti-friction composite material.

Locking finger for a unit for molding containers made of thermoplastic material

The invention relates to a half-mold comprising a joint face; an opposing assembly face), where the longitudinal cross-section of the assembly face is in the form of an arc of a circle centered on a reference axis. The reference axis is offset longitudinally towards the front relative to the joint face. The invention also concerns a molding assembly, a molding unit and a forming facility comprising such half-molds. The invention also concerns a method for producing such half-molds and a method for producing a surface for receiving such half-molds.

Half-mould having a cylindrical assembly face and production method

Disclosed is molding unit for the forming of containers made of thermoplastic material including: two half-molds delimited by a front joint face and by a rear assembly face, with the two half-molds being able to occupy a joined position via their joint face; and a molding cavity that is made of two parts in each joint face, where the cavity opens vertically upward via a passage opening. In the joined position, the assembly faces of the mold have two planes of symmetry that intersect at a central vertical axis of the mold. The central axis of the passage opening is offset transversely in relation to the central axis of the mold.

Molding unit with off-center neck passage opening

The invention relates to blowing equipment () that uses a pressurised fluid for blowing vessels from preforms of a thermoplastic material and including a body () and a neck (), wherein said equipment comprises a blowing mould () with a moulding cavity () in which the body () of a preform () can be placed, said mould () including an upper surface () from which protrudes the neck () of a preform () once the body () of said preform () is placed in the cavity (), and wherein said equipment () also includes a nozzle () with an end () shaped so as to be placed in functional sealed relation with the protruding neck () of the preform (). The end () of the nozzle () is connected to a means () for degassing the blowing fluid, capable of bearing tightly on the upper surface () of the mould () so as to define an inner volume () in which the blowing fluid blown under pressure into the preform () can be discharged after the preform () blowing operation. The equipment includes a degassing means capable of expanding the blowing fluid around the blowing cavity, wherein said means includes a plurality of channels () arranged around said blowing cavity, said channels () having one side opening into the inner volume of the degassing means () while the other side gives into an annular channel () for discharge into the atmosphere.

Equipment for blowing vessels of a thermoplastic material

The invention relates to a station for the stretching/blowing of preforms having an upward-facing open end. The inventive station comprises a bracket that supports a blow mould, a stretch rod and means for controlling the movements of the stretch rod. The aforementioned control means comprise: (i) an actuator, and (ii) a roller and a speed control cam, said roller coming into contact with the speed control cam as the stretch rod enters the blow mould, thereby controlling the speed with which the stretch rod enters the blow mould. The invention is characterised in that the speed control cam is disposed below the base of the blow mould.

Blow molding station for a container stretch blow molding plant and plant comprising one such assembly

A device for the moulding of thermoplastic containers by blowing comprises a mould () with two half-moulds (), each having a support () and a mould block () between which, in one half-mould, a compensating chamber () is defined, with elastic return means () and abutment means () being interposed, which are combined in unitary assemblies () each comprising: a bore () passing through the support and receiving a pin () having one end () fastened to the mould block and a first radial shoulder () against which bears the end (E) of a sleeve () screwed in the bore and having an outer head () capped by an axially displaceable housing (), with the elastic return means being interposed, which are preloaded by a nut () screwed on the free end of the pin against a second radial shoulder () of the pin, at the same time pushing the housing.
