摘要:
A blow mold unit in which, when clamping first and second blow cavity split molds which are fixed to first and second fixing plates and bottom molds which are fixed to a bottom mold fixing plate, pressure receiving members fixed to the first and second fixing plates are brought into engagement with the bottom plate fixing plate. Guide plates are fixed to the bottom mold fixing plate, and guided members capable of being brought into abutment with the guide plates are supported by first and second pressure receiving plates. The bottom mold fixing plate includes a first connecting portion to be connected to a bottom mold opening/closing unit and a second connecting portion to be connected to a moving and biasing member.

A molding machine includes a machine table, a mold unit and a pair of positioning units. The mold unit includes first and second molds mounted on the machine table and movable between a mold-closing position and a mold-opening position. The first and second molds abut against each other in the mold-closing position. Each of the positioning units includes a first positioner connected to the first mold, and a second positioner connected to the second mold. When the first and second molds are in the mold-closing position, the first and second positioners are operable to move to a locked state, where the first positioner is held by the second positioner to restrain the first and second molds from deforming away from each other.

An apparatus for shaping plastics material pre-forms into containers has a plurality of blow molding stations arranged on a movable carrier The blow molding stations have two part blow molds with a cavity inside in which the plastics material pre-forms are expanded. The blow molding stations have stressing devices which act upon the plastics material pre-forms to expand them with a flowable medium. At least one first bearing device is provided for movable mounting of the blow mold carriers with respect to each other and at least one second bearing device is provided for movable mounting of the first locking element with respect to the second locking element. At least one of these bearing devices is a slide bearing without lubricant or a bearing which is injection molded at least in part from a plastics material between bearing parts movable relative to each other.

Moving servo motors of molds in synchronization with the operations of platens which enables fine patterns or shapes to be formed even on a large molded article. A mold clamping device forms patterns or the like on a molded article by detecting a mold position of a second platen among first, second, third platens with digital mold opening/closing position detector, and driving servo motors for molds of the molds in synchronization with a digital mold opening/closing position signal from the digital mold opening/closing position detector.
摘要:
An arrangement for receiving a multi-part casting mold, in particular an at least two-part blow mold. A drive unit for displacing locking elements has a main cylinder with a main piston and a travel cylinder with a travel piston, wherein the travel cylinder is connected with the main piston of the main cylinder and is movable therewith. The travel piston has a piston rod, which is connected with the locking element and is mounted concentrically displaceably in the main piston. In the operating condition of the molding process, the travel piston abuts on the main piston, wherein the main cylinder provides the locking force to keep the mold closed during the molding process.

An apparatus is provided for the shaping of plastic pre-forms into containers with at least one blow moulding station arranged on a movable carrier, and having a blow mould carrier, a first blow mould carrier part and a second blow mould carrier part which is pivotable relative to the first blow mould carrier part to open and close the blow mould. The blow moulding station additionally has a locking mechanism to lock the first blow mould carrier part with respect to the second blow mould carrier part, and the locking mechanism has a first locking element on the first blow mould carrier part, and a second locking element on the second blow mould carrier part, for locking the carrier parts. A first magnetic element is movable relative to the first locking element and causes a movement of the first locking element by a magnetic interaction to lock the carrier parts.

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.
摘要:
A moulding device for the production of containers in thermoplastic material by blowing or blow-drawing, including a mould with two mould halves mutually mobile and provided with a locking device with first and second lock elements, in the form of catches, extending over the whole height of the respective mould halves and a projecting wing on one mould half, including a rotation surface on which a mobile piece is applied over the whole height thereof which includes the second lock element, such that, on blowing, the forces are taken by said mobile piece over the height of the mould by means of the rotation surface.
