摘要:
Blowing mold (10, 100) for blowing thermoplastic material containers, comprising two half molds (1, 2) and a device for the cyclic opening and closing of the half molds (1, 2) which comprises a control shaft connected to the half molds by means of connecting rods (14, 20) and a control hub (15). The control hub is provided with a plurality of holes appropriately positioned so that by choosing the holes to which the connecting rods are hinged, it is possible to change the maximum opening angle of the mold.

The invention relates to a mold for molding a hollow body from a preform, the mold defining a molding cavity having the shape of the a hollow body to be molded. The mold including a first part and a second part movable relative to each other between an opened configuration, wherein the preform can be loaded inside the molding cavity, and a closed configuration, wherein the molding cavity is formed. The mold further including a locking element arranged to maintain the mold in its closed configuration in a locked position of the mold. The locking element having at least a sleeve portion arranged around a portion of the first and second parts in the closed configuration such that the sleeve portion surrounds the portion of the first and second parts and prevents the mold from moving towards its open configuration in the locked position of the mold.

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.
摘要:
A molding device for the production of containers in thermoplastic material by blowing or blow-drawing, including a mold with two mold 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 mold halves and a projecting wing on one mold 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 mold by means of the rotation surface.
摘要:
A modular system for blow molding a container. The system may include a first portion, a second portion, and a third portion. The first portion and second portion may each include a shell, a mold removably coupled to the shell, and a top plate. The third portion may include a base and a base mold. The molds may be 3D printed. The molds together may define a blow mold cavity. The modular system may be used at lab scale, pilot scale, or full production scale. The molds may be durable and smooth enough for full production scale. Some embodiments are directed to methods for making a modular system for blow molding a container.

A blow molding device for a rotary bottle blowing machine includes: a support base including a power-input shaft and a mold-insert control shaft which are pivotally disposed on the support base and extend along an axial direction; a drive source for driving the power-input shaft and the mold-insert control shaft to rotate; and a mold assembly with a first and second movable mold inserts pivotally disposed on the support base. The mold assembly makes the first and second movable mold inserts pivot toward or away from each other, rotation of the power-input shaft makes a bottom mold unit move in the axial direction, and can lock the first and second movable mold inserts. A method for using the blow molding device includes steps of mold opening or closing, mold lifting, and mold locking, and these steps are performed by using a single drive source.

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.
