  • Patent number: 8939749
    Abstract: What is described is a blow-molding machine for plastic containers, comprising a plurality of platens for supporting blow mold halves, wherein at least two of the platens are in the form of movable multi-carriers for simultaneously supporting at least two blow mold halves which are assigned to different blow-molding cavities. Since the multi-carriers are driven in such a manner that at least one of the blow-molding cavities can be opened and at the same time at least one other of the blow-molding cavities can be closed by means of a continuous movement of the multi-carriers, acceleration and deceleration ramps can be reduced upon opening and closing and it is possible to gain process time for the blow molding.

The tooling further includes a pushup plate having a series of bottom contours that plug the otherwise open bottoms of the cavities when the pushup plate is against the bottom of the mold blocks. Each mold block is quickly attached to and detached from its supporting back plate using studs that fit into receiving holes on the back plate and cam locking shafts that are accessible from opposite side edges of the back plates. The back plates thus remain secured to platens of the bottle forming machine during change out of the tooling. Similarly, the push up plate has a pair of locking studs projecting from the underside thereof that are received within socket members attached to the machine. The socket members are provided with quick release threaded couplers that can be locked and unlocked by hand.

  • Patent number: 7378047
    Abstract: A method of inspecting wall thickness of blow-molded plastic containers includes providing a blow-molder having a plurality of molds and a plurality of associated spindles. The containers are inspected by impinging infrared light thereon and detecting the portion of the infrared light that passes through the container and converting the same into corresponding electrical signals which are delivered to a microprocessor. The microprocessor compares the electrical signals with stored information regarding desired wall thickness of the container and emits output thickness information. The microprocessor receives signals from sensors associated with the blow-molder relating to the position of the molds, the identity of the molds and the identity of the spindles in order that the wall thickness information that is determined by inspection can be associated with specific molds and spindles. The wall thickness information may be averaged over a period of time or a number of containers.

  • Patent number: 7374713
    Abstract: A method of manufacturing plastic containers. The method may comprise the steps of (1) forming a plastic container from a preform in a blow-molder, where the blow-molder comprises a plurality of molds and spindles; and (2) inspecting the plastic container after formation in the blow-molder. The containers are inspected by impinging infrared light thereon and detecting the portion of the infrared light that passes through the container and converting the same into corresponding electrical signals which are delivered to a microprocessor. The microprocessor receives signals from sensors associated with the blow-molder relating to the position of the molds, the identity of the molds and the identity of the spindles in order that the information that is determined by inspection can be associated with specific molds and spindles. The information may be visually displayed so as to provide feedback regarding the inspection process.

  • Patent number: 7354538
    Abstract: A system and a method for controlling a container manufacturing machine include a thickness monitor (10) for determining an average wall thickness of containers produced by the machine. The system uses the average wall thickness to adjust machine control to change operation of the machine and adjust the quality of the containers being produced. The system also responds to feedback from pneumatic devices (104), heaters (103), mechanical devices and temperature sensors (108, 109) to determine corrections to be made to the machine operation.

  • Patent number: 7300273
    Abstract: A system for forming a hollow body may include at least one closing unit positioned beneath the die of a tube extrusion device. The closing unit may include a first vertical closing plate and second vertical closing plate. Specifically, an upper horizontal closing plate is cantilevered to the first vertical closing plate carrying an upper mold half, while a lower horizontal supporting plate is cantilevered to the second vertical closing plate carrying a lower mold half. At least one hydraulic cylinder may connect to the horizontal supporting plate and be adapted to vertically displace the lower horizontal closing plate. The closing unit is configured in such a way that when the vertical closing plates are moved toward each other, the upper horizontal closing plate and the lower horizontal supporting plate interlock. The system can be configured to produce oblong hollow bodies requiring a horizontal mold parting plane.

  • Patent number: 7153127
    Abstract: A mold system for blow molding hollow plastic containers includes an extruder for providing a hollow tube of plastic material having a longitudinal axis. Three mold segments include at least two mold segments that are movable against the third mold segment, in directions perpendicular to the tube axis, between a closed position in which the mold segments form a hollow mold cavity in which the tube is captured and an open position spaced from the tube axis. A blow pin is disposed on one of the mold segments to pierce the tube in the closed position of the mold segments. One of the mold segments may be a mold core movably mounted on a second of the mold segments, and cylinders are mounted on the second mold segment for moving the mold core between an extended position and a retracted position with respect to the second mold segment. The blow pin may be movably mounted on the mold core.

  • Patent number: 7114945
    Abstract: The shifting of the parting line between split molds due to mold clamping force is prevented. A blow mold device (11) wherein a pair of split molds forming a blow cavity (12) are a set of molds, and a plurality of such sets are attached in parallel to mold-attaching plates (15, 16) with a clearance defined between adjacent sets. One split mold (13) is attached by bolts (17) inserted in bolt holes (23) in the form of loose holes in the mold-attaching plate (15) in such a manner as to allow relative lateral shifting of the split mold (13) and mold-attaching plate (15). The other split mold (14) is fixedly attached to the mold-attaching plate (16) by locating pins (18) and bolts (17). A joint is installed that integrally connects the two split molds to their parting surface and that is composed of a taper pin (19) and a socket (21) for preventing the shifting of the parting line.

  • Patent number: 6923637
    Abstract: Each of the clamping plates of the closing unit of the blow molding machine has secured thereto a pivotable locking means which in the calibration position in the swung-up state comes into engagement with a plate which is part of the calibration device. A short friction-type connection which is symmetrical relative to the mold parting plane is thereby established between the blow mold and the calibration cylinder during calibration so that the calibration forces are transmitted in an exact manner. The locking means swing downwards when the blow mold is opened and/or the closing unit returns to the head station. Collisions with other machine parts are thereby ruled out.

  • Patent number: 6893602
    Abstract: Shuttle blow molding apparatus having an extruder for substantially continuously extruding a thermoplastic material in tubular form at a moldable temperature downwardly along a vertical axis. A first finite length of the thermoplastic material is grasped by a first mold set, which then moves outwardly and downwardly with respect to the extruder to provide clearance for a second mold set to move to a position to grasp a second finite length of the extruded thermoplastic tube. The first mold set is then moved horizontally away to permit the finite length of thermoplastic tube therein to be blown into a hollow article, and thereafter removed from the first mold set at a second position of the first mold set.
