Abstract:
An injection blow molding apparatus comprises: a first oil supply section which has a hydraulic drive source composed of a drive motor, whose number of revolutions can be controlled, and a hydraulic pump and which supplies oil from an oil tank to an injection mold drive unit provided in an injection mold unit; and a second oil supply section which has a hydraulic drive source composed of a drive motor, whose number of revolutions can be controlled, and a hydraulic pump and which supplies oil from the oil tank to a blow mold drive unit provided in a blow mold unit, the second oil supply section being provided independently of the first oil supply section.
Abstract:
A molding die device is provided for bringing a resin sheet into close contact with a pair of dies by vacuum suction from a cavity surface to perform molding. An outer frame portion is formed integrally with an outer peripheral portion of the respective dies arranged to face each other. Moreover, one of the dies has a recessed portion formed at the position of the one of the dies facing the outer frame portion of the other die and configured so that the outer frame portion of the one of the dies can be housed in the recessed portion. The outer frame portion is formed to protrude most in each die. Upon molding, the dies are clamped together after vacuum suction has been performed with the resin sheet being arranged in contact with the outer frame portions.

Abstract:
A blow molding machine 1 has a blow molding section 10, an ejection section 20, and a delivery unit 100. In order to deliver a plurality of containers B to a device 200 of a post-process subsequent to the blow molding machine, the delivery unit includes a rail for holding, delivering and guiding the plurality of containers, and an elevation block raised and lowered relative to the rail. The elevation block includes a plurality of blades, an endless member to which the plurality of blades are fixed at a blow molding pitch, and a drive portion for driving the endless member to run.
Abstract:
A blow molding device for a rotary bottle blowing machine includes just needs one drive source to rotate a coaxial drive device, then first, second and third control members will move the movable mold portion, the bottom mold portion and the locking block, to carry out the operation of mold opening and closing, lifting of the bottom mold portion, and locking and unlocking of the locking block. Therefore, the structure of the blow molding device is simplified, and operation efficiency is improved, and cost is reduced.
Abstract:
The invention relates to a method and a device for blow-molding containers. Following thermal conditioning inside a blow-mold of a blow-molding machine, a preform (1) is formed into the container (2) by means of blowing pressure. The necessary blow-molding gas (P1, P2) is provided by a supply device. The stored, pneumatic pressure energy inside the blown container is at least partially transformed into another form of energy.
Abstract:
Plastic container manufacturing plant comprising devices for injection-compression of plastic in molds and effected by means of at least one rotary carousel actuated by electro-pneumatic actuators, of the single-stage type integrating at least one first rotary carousel (2) for molding of the preforms and a second rotary carousel (7) for stretch blow molding of the preforms. Moreover, the plant comprises a transport system (5) between said first (2) and second rotary carousel (7) comprising further handling wheels, of which at least one (8) comprises means for thermal conditioning of the preforms.
Abstract:
Machine for forming containers (3a), comprising a unit (2) for extruding tubes (3) made of plastic, associated with an electric extrusion motor (200), a blowing unit (5) associated with an electric blowing motor (500), a mould (4) for containing the containers (3a), formed by two half-moulds (4a,4b) movable, upon operation of an associated electric mould motor (400), in a longitudinal direction X-X, the unit formed by the mould (4) and by the associated mould operating motor (400) being displaceable, upon operation of an electric displacement motor (300), in a transverse direction (Y-Y) from a first position substantially aligned with the extrusion unit (2) into a second position substantially aligned with the blowing unit (5) and vice versa, comprising at least one base power supply/recovery module (2000) and at least one first control module (2300) connected to said displacement motor (400) for controlling the acceleration/deceleration thereof.
Abstract:
The invention relates to an arrangement and to a method for the electromechanical drive for mold closing systems and calibration blow mandrel systems in blow molding machines, wherein the arrangement for the drive of an extrusion blow molding machine includes a push mechanism (3; 11), a push rod (4; 12) and exactly one electric motor (1; 9), wherein the push rod (4; 12) is movable by the push mechanism (3; 11) which is driven by the electric motor (1; 9), wherein the electric motor (1; 9) has an additional braking device (2; 10) which can be activated on the reaching of a required torque or a required force of the electric motor (2; 10) to hold the push rod (4; 12) in a state of maximum tension in its instantaneous position.
