Blow molding clamping linkage system

A pivot casting component (210) used in an apparatus for extrusion blow molding polyethylene teraphthalate ("PET") is disclosed. The pivot casting is designed to provide increased strength and increased reliability over prior components with the blow mold clamping linkage system. Prior art pivot elements were designed and fabricated from separate elements such that weak points, and stress concentration points were created. Such weak points resulted in the pivot element being a weak component in the blow mold clamping linkage system. The inventive pivot casting is cast as a single component from higher strength materials, with an improved geometry to increase component strength, durability and overalll system reliability. Ina preferred embodiment, the air side pivot casting is fomred from 80-55-06 ductile iron resulting in a 40% increase in tensile strenth over prior pivot components.

Rotary moulding machines

The invention is directed a rotary molding machine (20) having a wheel mounted for rotation on a pair of shafts positioned along the rotational axis of the wheel. A first shaft cooperates with a first turntable of the wheel and a second shaft cooperates with a second turntable. The first and second turntables extend transversely to the rotational axis. A plurality of modular mold clamp assemblies (100) are positioned on the wheel, with each modular mold clamp assembly being moveable between an open and a closed position. Each modular mold clamp assembly has mounting areas which are mounted with respective mounting locations each turntable. The modular mold clamp assemblies provide the structure and rigidity between the turntables to help maintain the turntables in position relative to each other.

Adjustable platen assembly for use in a mold clamp station

An adjustable platen assembly (126) and method of assembly therefore. The platen assembly has a platen and a pressure plate (212) attached to the platen. The pressure plate may be rotatable around a longitudinal axis of the rod according to the size of a mold half mounted to the platen. The platen assembly may have at least one platen support (246) mounted to the platen. The at least one platen support may be rotatably mounted to the mold clamp. The at least one platen support can be rotated according to the size of a mold half mounted to the platen. The adjustable platen provides support to the mold half to reduce the amount of deformation to the mold half that is caused by the application of a closing force.

Molding device

The invention relates to a moulding device comprising a device for displacing at least one moulding tool ( 10,10 a ), especially for the production of geometrics of plastic containers, by means of a linking motion ( 12 ) which brings the respective moulding tool ( 10,10 a ) into a closing position (I-I) for at least the close of the mould. The linking position ( 12 ) can be operated by a drive ( 14 ). Based on the linking motion ( 12 ) a novel drive and displacement concept is provided, enabling the hydraulic means to be totally dispensed with and a drive, preferably an electric drive, to be used, especially in the form of a stepping motor.

Mold for large capacity containers

This relates to a blow mold of a large capacity which is particularly configurated to replace two adjacent blow molds in a blow molding machine of the Ferris wheel type. The blow mold includes an inner mold half which will bridge the supports for two existing smaller molds and an outer mold half which is formed in two segments with each of the segments being independently mounted on the supports for two separate prior radially outer blow mold halves. Thus, an existing machine may be readily converted to make much larger blow molded articles then those for which it was originally intended. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of this application.
