摘要:
A temperature adjustment mold for a blow molding apparatus provided with at least an injection molding unit that injection-molds a preform made of a resin and having a bottomed shape, a temperature adjusting unit that adjusts a temperature of the preform manufactured by the injection molding unit, and a blow molding unit that blow-molds the preform to manufacture a resin container, the temperature adjustment mold including a cavity mold that accommodates the preform, and an air introduction member that includes a fitting core and a rod member with a multiple-tube structure to form at least three concentric air flow paths.

In a blow moulding machine for the production of plastics material containers, during a blow mould procedure, the container to be expanded is supplied with blow moulding air from a first gas preparation device on the one hand or from a second gas preparation device on the other hand. During this procedure a cooling of the base of the container is additionally carried out.

In a method for manufacturing a resin container, in the adjusting the temperature of the preform, the preform is accommodated in a cavity mold, a refrigerant introduction member is inserted into the preform, the refrigerant introduction member including a first flow path and a second flow path which are different in introduction or discharge position of a refrigerant, the preform is cooled by bringing the preform into close contact with an inner wall of the cavity mold at a pressure of the refrigerant introduced from the refrigerant introduction member. When the preform is cooled, cooling is performed by switching between a first cooling blow for introducing the refrigerant from the first flow path and discharging the refrigerant from the second flow path and a second cooling blow for introducing the refrigerant from the second flow path and discharging the refrigerant from the first flow path.

A process and a device for the manufacture of a hollow body, particularly of a heat-resistant hollow body, which is molded out of a heated preform of thermoplastic plastic in a contoured blow mold through the introduction of a first medium into the preform, which medium is stored in a first medium storage unit and is under a pressure (p1) (preblowing phase), and the more or less simultaneous stretching of the hollow body through a stretching rod and the introduction of a second medium in the hollow body, which medium is stored in a second medium storage unit and the pressure of which (p2) is higher than the pressure of the first medium (p1) (final blowing phase), and which is cooled by a third medium, which is medium stored in a third medium storage unit (rinsing phase), whereby the preblowing medium is under a pressure of approximately 2-20 bar, the final blowing medium is under a pressure of approximately 15-45 bar, and the cooling medium is under a pressure of approximately 30-45 bar.

摘要:
The invention relates to a method and a device for blow-molding containers. Following a thermal conditioning process, a parison is stretched by a horizontal bar inside a blow station provided with a blow mold, and is molded into a container by the effect of the blowing pressure. In order to carry out the blow-molding, pressurized gas is introduced into the container. The horizontal rod is hollow at least in parts. Once a maximum blowing pressure has been reached in the blow station and at the earliest at the beginning of a pressure drop, a cooling gas is guided out of the horizontal bar towards the bottom of the blown container.

Following a thermal conditioning process, a parison is stretched by a horizontal bar inside a blow station provided with a blow mould, and is moulded into a container by the effect of the blowing pressure. In order to carry out the blow-moulding, pressurised gas is introduced into the container. The horizontal rod is hollow at least in parts. Once a maximum blowing pressure has been reached in the blow station and at the earliest at the beginning of a pressure drop, a cooling gas is guided out of the horizontal bar towards the bottom of the blown container.

摘要:
This invention relates to a method of fabricating a bottle-shaped container of saturated polyester having superior mechanical strength, very low degrees of age and high temperature deformation, and superior dimensional stability. The piece for forming the bottle-shaped container is heated to an orientation temperature, is biaxially oriented in a blowing mold and is then thermally set by maintaining the outer wall surface of the expanded container in contact with the inner wall surface of the mold, which is kept at a temperature in the range between the glass transition point and the crystallization temperature, for longer than 5 seconds. The blowing mold is formed with the size adjusted in capacity by approx. 6% to allow for shrinkage of the product container when the container is exposed to a high temperature greater than 70.degree. C. and then left to stand, so as to thereby obtain a container of accurate capacity.
