A male element (100) of a mould (10) for the compression moulding of a parison comprises: a die (110), extending along a longitudinal axis (A) and including a body (112) having, inside it, a longitudinal cavity (113) 5 extending along the longitudinal axis (A) and, at one end of it, a socket (111) in communication with the longitudinal cavity (113); a stretching rod (120), slidably inserted in the longitudinal cavity (113) and including a terminal portion (121) at one end of it, the stretching rod (120) being movable relative to the die (110) between a retracted position, in which the 10 terminal portion (121) is housed inside the socket (111), and an extracted position, in which the terminal portion (121) is extracted from the socket (111).

Devices, systems, and methods are generally directed to cooling preforms in a receptacle having a controllable shape. As compared to cooling preforms in a receptacle having a fixed shape, the devices, systems, and method of the present disclosure may facilitate faster and more reliable post-processing of preforms. As an example, the devices, systems, and methods of the present disclosure may reduce the likelihood of transfer issues associated with moving a preform into the cavity while also facilitating faster cooling of the preform disposed in the receptacle.

A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is then removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.

A blow mold is provided and includes a cavity mold composed of a pair of split molds for forming a cavity in which a preform is to be housed, a link member having one end side pivotably supported by a shaft member, and having on another end side a recess insert die which presses the preform during blow molding to form a grip portion, and a cam member which is provided lateral to the cavity mold so as to be linearly movable, and which presses the link member in accordance with a linear movement thereof to pivot the link member.

A manufacturing apparatus for manufacturing a resin container, the manufacturing apparatus includes an injection molding part, a temperature adjustment part, a blow molding part, a take-out part, and a rotation plate. The temperature adjustment part includes a first temperature adjustment mold into which the preform is inserted, the first temperature adjustment mold being configured to cool the preform from an outer surface of the preform, a second temperature adjustment mold into which the preform is inserted, the second temperature adjustment mold being configured to cool the preform from an inner surface of the preform, and wherein, in the temperature adjustment part, the preform is cooled so that at least the outer surface temperature of the preform is lowered within a temperature range from 10? C. to 50? C. as compared to the outer surface temperature of the preform when the preform is carried into the temperature adjustment part.

Provided is a method for manufacturing a container 10 made of resin, the method including an injection molding step S1, a temperature adjustment step S2, and a blow molding step S3. In the temperature adjustment step S2, a preform 11 is accommodated in a cavity mold 31, an air introduction member 32 is brought into airtight contact with the preform 11, the air is supplied from a blowing port of the air introduction member 32 into the preform 11, and the air is discharged from a discharge port of the air introduction member 32 to an outside of the preform 11, so that the preform 11 is in close contact with an inner wall of the cavity mold 31 and is cooled.

A manufacturing method includes an injection molding process of injection-molding a preform, a temperature adjustment process of temperature-adjusting the preform while cooling the preform, and a blow molding process of blow-molding the temperature-adjusted preform to manufacture a resin container. In the injection molding process, a step portion thicker than at least an engagement groove of a neck portion is formed between the neck portion and a body portion of the preform.

The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding.

A temperature adjustment device and a temperature adjustment method for a preform in a blow molding device with which it is possible to reduce a molding cycle time is provided. A temperature adjustment device for a preform in which a hollow rod member is inserted into an injection-molded, bottomed preform retained by a retention member, and a first air circulation path is formed between the preform and the hollow rod member to adjust the temperature of the preform. The temperature adjustment device is characterized in that a flow path adjustment member is fitted and attached to the outer periphery of the hollow rod member, whereby the cross-sectional area of the first air circulation path is partially adjusted and changed.

A blow molding device in which a preform is injection-molded, the injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10? C. or more lower than the glass transition temperature of the preform.
