Embodiment Construction

[0051] For the following description, elements having similar, similar or identical functions will be denoted by the same reference numerals.

[0052] For the following description, for each mold base 32, non-limitatively, the figure 1 The first mold base 32 on the left side is by coordinate system " L, V, T " and is positioned at figure 2The second mold base 32 on the right is longitudinally oriented, vertically oriented and transversely oriented represented by "L', V, T'". The transverse directions “T” and “T′” and the longitudinal directions “L” and “L′” are thus fixed with respect to each mold base 32 . For each die shoe 32, the longitudinal direction "L", "L'" is oriented in a direction from rear to front towards the other die shoe 32 when the die shoe 32 is in the closed position.

[0053] The term "inner", respectively "external" is also used to denote a surface or direction towards the inside of the housing 38 of the mold base, respectively towards the outside of th...

Abstract

The invention relates to a molding device (10) for a container-making machine, comprising: two mold halves (14); for receiving an associated mold half (14); and at least one retractable fixed bolt (58) slidably mounted in at least one mold holder (32) between an operating position and a stowed position, in In the working position, the fixed bolt is extended so that in the installed position the associated mold half (14) is detachably fixed against the bottom (40) of the associated housing (38), in the stowed position the fixed lock Tongue release mold half (14), characterized in that each deadbolt (58) and / or associated mold half (14) includes a fastening ramp (74) which is inclined to The fixed bolt (58) slides from its stowed position to its working position so that the mold half (14) is pressed against the bottom (40) of the housing (38).

Description

technical field [0001] The present invention relates to a molding device for a machine for the production of containers, especially bottles. [0002] The invention relates more particularly to a molding device of a manufacturing machine for manufacturing containers, in particular bottles, of thermoplastic material by blow-molding or stretch-blowing preforms, the molding device comprising: [0003] - two mold halves each provided with a cavity half, each mold half comprising a front joint surface and a rear surface; [0004] - two die holders, each provided with a housing for receiving the associated mold half in the installed position, in which the rear surface of the half-mold is in contact with the bottom of the housing; and [0005] - at least one retractable fixed bolt, said fixed bolt is slidably mounted in at least one die holder between an operative position and a stowed position, in which said fixed bolt protrudes to pass through each At least one locking surface of ...
