Problems solved by technology

[0009] [09] This technique has been and continues to be satisfactory, but it has the disadvantage that the presence of the central socket on the interface makes it possible to place and store the mold bottom part against the socket, which would cause the socket to axially deviation, which may make it difficult or even impossible to insert the base piece into the seat, thus preventing the base piece from joining the support

Embodiment Construction

[0026] [26] Die bottom part 1 is shown in figure 1 , which is in the shape of a metal block (made of steel or aluminum alloy), the mold bottom part has a hollow mold cavity 2 on its upper surface, and this mold cavity is used to give its shape to the bottom of the container.

[0027] [27] The mold bottom part 1 is mounted in a rigid but non-permanent manner by a detachable fixing device 3 on a support 4, which is hereinafter referred to as a base, and may be along the general symmetry of the mold bottom part 1 and the base 4 The axis A coincides with the axial direction of movement.

[0028] [28] The bottom 4 is provided with ducts 5 for the flow of the heat-carrying fluid, which are opened out in the form of a helix or, as a variant, in the form of concentric circles on the lower surface of the bottom 4 opposite the cavity 2 .

[0029] [29] The fixing device 3 comprises a male part 6 and a female part 7 . According to one embodiment, the female part 7 is carried by the ba...

Abstract

A removable device (3) for attaching with fluidic connection a mould base (1) on a medium (4), said device (3) comprising a male part (6) and a female part (7), said male part (6) having a truncated-cone-shaped surface (10), said female part (7) comprising a locking mechanism (26) including balls (33) suitable for engaging with said surface (10), a device wherein the female part (7) comprises a peripheral cage (27) provided with holes (2) wherein are housed the balls (33), and a lock (34) provided with an annular ramp (41), mounted around said cage (27), that can be manually accessed and moved between a locking position wherein the ramp (41) is arranged in line with the balls (33), and a release position wherein the ramp (41) is spaced apart from the balls (33).

Description

technical field [0001] [01] The present invention relates to the field of container manufacture, in particular the manufacture of containers by blow molding or stretch blow molding. Background technique [0002] [02] The blowing of the container is carried out in a mold equipped with a cavity into which a preheated blank (usually made of thermoplastic material) is placed and pressurized so that it has the The cavity shape corresponds to the desired shape. [0003] [03] Modern molds generally consist of three parts: two mold halves, which are hinged in a plane perpendicular to the main axis of the mold, and which either translate or rotate about a common hinge (thus the mold is called a "folder" type); Mold bottom part that moves parallel to the mold axis. [0004] [04] The temperature of the mold is generally adjusted so that it cools in the most common applications, or heats it up in HR (thermal resistance) type applications where the container is subjected to heat fixing...
