Embodiment Construction

[0076] figure 1 Shown is a part of a molding unit 1 comprising a male mold element 2 which can also be found in figure 2 see in.

[0077] The male mold element 2 can be used to obtain an object 5 made of polymer material by injection molding or compression molding. The object 5 may be a hollow object such as, for example, a cap for a bottle, or more generally a cap for a container. In this case, the male mold element 2 cooperates with an unillustrated female mold (female mold) element included in the molding unit 1 .

[0078] Alternatively, the object 5 may be a substantially flat object, such as a seal for a bottle cap, or more generally a container cap. The seal can be molded directly inside the previously formed cap by means of the male mold element 2 . In this case, the molding unit 1 comprises, instead of the female molding element, a support element, not shown, for supporting the lid on its inner side on which the seal has to be formed.

[0079] The molding unit 1 ...

Abstract

A male mold element comprising a cooling circuit with first access means (15, 16; 115, 116; 215) obtained in a first part (6; 106; 206; 306; 406; 606) of the male mold element , 216; 315, 316; 415, 416; 615, 616) and the second access device (20; 120; 220) obtained in the second part (7; 107; 207; 307; 407; 607) of the male mold element ; 320; 420; 620), first access means (15, 16; 115, 116; 215, 216; 315, 316; 415, 416; 615, 616) and second access means (20; 120; 220; 320 ; 420; 620) distributed around the longitudinal axis (Z; Z1; Z3) of the male mold element, so that there is a first part (6; 106; 206; 306; 406; 606) relative to the second part (7; 107; 207 ; 307; 407; 607) a plurality of angular positions, in which the first access means (15, 16; 115, 116; 215, 216; 315, 316; 415, 416; 615, 616) In fluid communication with the second access means (20; 120; 220; 320; 420; 620).

Description

technical field [0001] The present invention relates to a malemould (malemould) element that can be used for injection molding or compression molding of objects made of polymer material. In particular, the male mold element according to the invention can be used to shape the inner surface of hollow objects, such as caps for containers, or preforms for containers and in particular preforms according to bottles or containers pieces. The male mold element according to the invention can also be used for molding substantially flat objects, for example seals for container lids. Background technique [0002] International patent application WO 2007 / 028702 describes a male mold element for internally formed container closures. The male mold element described in WO2007 / 028702 comprises a central core and a tubular part arranged outside the central core. A cooling circuit is formed in the central core and in the tubular member such that a cooling fluid can flow from the central cor...
