Mold for blow molding, method for manufacturing resin container using same, and resin container

A production apparatus of a two-layer preform including an inner layer preform and an outer layer preform includes: an outer layer cavity mold for injection-molding the outer layer preform. A bottom surface of the outer layer cavity mold is provided with a protrusion for separating the inner layer preform disposed in the outer layer cavity mold from the bottom surface.

Apparatus for producing resin molded article, method for producing resin molded article, and resin molded article

A mold includes a first mold for receiving a neck mold that holds a neck part of a resin preform having a bottom, and for enclosing the preform inside, and a second mold inserted into the neck mold. At least one of a first sliding surface between the neck mold and the first mold and a second sliding surface between the neck mold and the second mold includes a solid lubricant embedded therein.

Mold, blow molding device, and injection molding device

This resin-made container is provided with: a neck portion having a content inlet-outlet portion; a lateral surface portion connected to the neck portion; and a bottom portion that is disposed on the side opposite to the neck portion and that is connected to the lateral surface portion. The resin-made container is produced by a stretch blow molding process. The bottom portion has formed therein a bulge section that protrudes downward in the vertical direction. The bulge section is disposed in an eccentric region, of the bottom portion, positioned outside a region demarcated by perpendicularly projecting an opening plane of the inlet-outlet portion of the neck portion.

Resin-made container, resin-made container manufacturing method, resin-made container manufacturing apparatus, and mold

A hollow article is molded in a state where an inner surface of a neck portion including an inner screw portion is held by an inner neck mold, and then, the hollow article is demolded from the inner neck mold by inserting an ejection rod into the hollow article to be engaged with an inner surface of the hollow article and rotating the hollow article together with the ejection rod.

Hollow article molding method and molding apparatus and hollow article

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

An injection molding mold including a neck mold forming an outer surface of a neck portion of a hollow article, an injection cavity mold forming an outer surface of a body portion of the hollow article, and an injection core mold forming an inner surface of the hollow article, in which the injection core mold includes an outer core mold forming an inner surface of the neck portion including an inner screw portion and, while rotating along the inner screw portion, being movable along a rotation axis thereof, and an inner core mold forming an inner surface of the body portion of the hollow article having a smaller diameter than that of the neck portion and being linearly movable inside the outer core mold along the rotation axis.

Injection molding mold, and injection molding method for hollow article

A mold includes a link member including a protruding grip forming part configured to form a grip part to a portion of a container by pressurizing a portion of a preform that is expanded during blow molding; and a piston member configured to move forward toward a cavity to thus press and rotate the link member. The grip forming part has: a pressurizing surface configured to pressurize the portion of the preform; and a contact surface configured to come into contact with the piston member, wherein the piston member has a pressing surface that comes into contact with the contact surface and presses the grip forming part toward an inside of the cavity when moving the pressurizing surface, and wherein the pressurizing surface is arranged at an opposite side of the contact surface of the grip forming part with respect to a moving direction of the piston member.

Mold, blow molding apparatus, and blow molding method

A handle of the present invention is a handle configured to be attached on a side surface of a container body along an upward and downward direction of the container body, the handle including an elongated grip portion, an upper attachment arm provided on an upper side of the grip portion, and a lower attachment arm provided on a lower side of the grip portion, wherein on at least a part of a lower surface of a distal end side of the upper attachment arm, a first inclined surface is formed to be inclined toward A center portion of the grip portion, and on at least a part of an upper surface of a distal end side of the lower attachment arm, a second inclined surface is formed to be inclined toward the center portion of the grip portion.

Handle and container with handle

An apparatus for molding a handle-equipped container is provided. The apparatus has a gripping mechanism sectionwhich comprises a first gripping memberhaving a pair of first chuck membersfor grasping a preform, and a second gripping memberhaving a pair of second chuck membersfor grasping a container handlein association with the action of the first gripping member. The apparatus can simultaneously grasp a plurality of the preformsand a plurality of the container handlesand reliably transport them to a blow molding section.

Apparatus for molding handle-equipped container, and mold and mold unit for use in same

A container with a handle, in which a handle is engaged with a portion of the container, is manufactured by arranging the handle in a handle arrangement part, inserting a bottomed tubular preform into a cavity of a mold and performing blow molding. The mold includes an inner wall surface that forms an external shape of the container and a pressurizing member that forms a handle engaging part engaging with the handle to a portion of the container, and the pressurizing member is capable of moving between a first position which is a position at an outer side of the inner wall surface and a second position at which a portion of the inner wall surface is formed.

Mold for container with handle

An apparatus for forming a handle-equipped container comprises: a transport sectionprovided with a transport line, the transport linealternately transporting a first transport jigholding a preform, and a second transport jigholding a container handle, the transport sectiontransporting the preformand the container handleto a blow molding sectionalong the transport line; and a supply sectionfor lowering the container handle, held in an inverted state, and supplying the container handleto the second transport jig. The second transport jigsupports at least a pair of opposite side surfaces of the container handle

Apparatus for forming handle-equipped container, transport jig, and container handle

A blow molding method includes a primary blow molding step that molds a preform () in a primary blow mold (A) that includes a primary temperature control section () to obtain an intermediate molded article (), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article () that has shrunken in a secondary blow mold that includes a secondary temperature control section () to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.
