There is provided a mold unit for cooling a preform that has been injection-molded, the preform having a bottomed shape and made of a resin, the mold unit including a core mold having an outer shape corresponding to an inner shape of the preform, and being insertable into the preform, in which a flow path for a temperature adjustment medium extending in an axial direction of the core mold is formed inside the core mold, the flow path is formed at a position displaced in a circumferential direction of the core mold, and a position of the flow path is adjustable in the circumferential direction.

Die unit, blow molding device, and blow molding method

In a manufacturing method for a delamination method, in a second injection molding including forming a second layer on an inner peripheral side of a first layer of a preform having a bottomed cylindrical shape, a second resin material is guided from an opening portion formed in the first layer toward the inner peripheral side of the first layer, and a locking portion protruding from the opening portion toward an outer peripheral side of the first layer is integrally formed with the second layer.

Manufacturing method and manufacturing apparatus for delamination container

There is provided a cooling mold unit for cooling a preform that has been injection-molded, the preform having a bottomed shape and made of a resin, the cooling mold unit including a core mold having an outer shape corresponding to an inner shape of the preform, and being insertable into the preform, in which an exhaust port configured to discharge air from an inside of the preform through an inside of the core mold is provided at a tip end portion of the core mold facing a bottom portion of the preform.

Molding unit for cooling resin molded article, blow molding device, injection molding device, and method

In a manufacturing method for a delamination container, in a first injection molding, a first recess portion is formed by a first protrusion portion in at least part of a first layer. In a second injection molding, a second recess portion which penetrates the first layer and through which a surface of a second layer is exposed is formed in a preform by inserting a second protrusion portion into the first recess portion. During a blow molding, the second recess portion is stretched to form an air introduction hole in an outer layer of the delamination container.

A method for manufacturing a resin container, the method including: injection-molding a bottomed preform made of resin; and blow-molding the preform to manufacture a resin container, in which the injection molding includes filling a cavity formed by at least an injection core mold and an injection cavity mold with a molten resin to form the preform, and a first groove that extends from a bottom portion defining portion to a neck portion defining portion is formed in a surface of the body portion defining portion of the injection core mold.

Method for producing resin container, injection core mold, mold for injection molding, and device for producing resin container

An object of the present invention is to provide a blow molding device, a blow molding method, a mold unit, and a jig capable of shortening a molding cycle time. There is provided a blow molding device (), in which the blow molding device () includes an injection molding part () injection-molding a preform () having a neck portion () on an open side and a main body portion () on a closed side, a temperature adjustment part () adjusting a temperature of the preform () molded by the injection molding part (), and a blow molding part () blow-molding the preform () whose temperature has been adjusted by the temperature adjustment part (), and the temperature adjustment part () include a conditioning core mold () that is in contact with substantially an entire inner surface of the main body portion () and a conditioning cavity mold () that is in contact with substantially an entire outer surface of the main body portion (), and compress and deform the main body portion () of the preform () into a desired shape with the main body portion () sandwiched between the conditioning core mold () and the conditioning cavity mold ().

Blow molding device, blow molding method, and mold unit

One purpose of the present invention is to provide a mold unit which is capable of achieving improvements in both energy efficiency and heat resistance performance; a blow molding apparatus; and a blow molding method. The present invention is provided with: a first mold part for performing a first step in which a preform is subjected to heat-set blowing at a first temperature; and a second metal mold part for performing a second step in which an intermediate molded body blow molded as a result of the heat-set blowing is blow molded at a second temperature lower than the first temperature, to produce a container. The first mold part and the second mold part are disposed adjacently to each other.

Two step blow molding unit, apparatus and method

A blow molding method includes: performing a primary blowing on a resin preform to form an intermediate molded product; and performing a final blowing on the intermediate molded product to form a final molded product, and at least one step of performing the primary blowing and the final blowing includes a thinning step of continuously repeatedly performing, within a predetermined time, steps of: stretching an object by blowing; and contracting stretched parts of the object by exhausting blown air.

Blow-molding method and blow-molding apparatus

In a fixing memberformed with an insertion holefor inserting an elevation rod, a communication holecommunicating with the insertion holeis formed to open at a side surface of the fixing member. A key memberis inserted into the communication holeand engaged with a key grooveprovided at the distal end of the elevation rod. By so doing, the elevation rodand the fixing memberare coupled together.
