Embodiment Construction

[0031] exist figure 1 The apparatus 1 shown in an incomplete and diagrammatic manner in includes a mold 2 having a die 4 and a cavity 6 mounted for mutual movement as indicated by the double arrow F1 and designed for molding plastic material . In order to keep the plastic material at a temperature suitable for moulding, the die 4 and the cavity 6 are equipped with respective ducts 4A, 6A through which a heat transfer fluid heated to a suitable temperature flows.

[0032] The pipes 4A, 6A are supplied with heat-carrying fluid via hoses 8 , represented by lines indicating their axes, and connected to headers 10 .

[0033] In practice, the plant 1 comprises a plurality of dies of the same type as the die 2, and the header 10 enables the supply of different ducts equipped with the dies and cavities of the different dies, it being conceivable that any one die or cavity can be Equipped with a plurality of such pipes.

[0034] The header 10 passes along the axis X 10 formed by st...

Abstract

The present invention relates to manifolds for distributing or collecting fluids and molding apparatus comprising such manifolds. The header is easier and more economical to adapt to the conditions of its use. The header includes a stack of at least a plurality of tubular modules and a first support, and at least one tie rod for compressing the stack in a configuration, adjacent portions of the stack overlapping in a sealed manner. The tie rod can be secured relative to the first support in rotation about its longitudinal axis and in translation parallel to said axis. The tie rod is equipped with a clamping nut which in the tightened position exerts a compressive force on the stack of modules and first supports. a bearing surface adapted to be axially fastened relative to the first support and adapted to supportively receive a surface of the clamping nut when said clamping nut is moved in the loosening direction, said bearing surface relative to the upper The surface of the clamping nut in the tight position is disposed at an axial length that is less than the smallest of the seal overlap lengths of two adjacent portions of the stack.

Description

technical field [0001] The present invention relates to headers for distributing or collecting fluids, and molding apparatus comprising such headers. Background technique [0002] In the field of molding equipment, it is known to use manifolds to distribute fluids, such as heat transfer liquids, between one or more inlets and one or more outlets designed for connection to multiple points where the heat transfer The fluid is used in particular to heat one or more parts of the mold to a given temperature and to maintain said parts at said given temperature. [0003] In the field of plumbing engineering, it is known from US-A-4848391 that headers can be realized by stacking juxtaposed modules, the respective internal volumes of which form a central duct and are equipped with radial outlets. The modules are assembled together by tie rods, or retaining rods, each threaded on at least one of its two ends, which apply a compressive force to the stack of modules, enabling them to l...
