Mold, blow molding apparatus, and blow molding method
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.
APPARATUS FOR BLOW MOLDING PLASTIC CONTAINERS, PARTICULARLY BOTTLES
An apparatus for blow molding plastic containers, particularly bottles, including a blow molding carousel, which can rotate about a main rotation axis and is functionally connected, at a first transfer station and at a second transfer station, to a line for feeding the preforms and to a line for unloading the bottles, the blow molding carousel supporting, at its peripheral region, a plurality of forming units arranged around the main rotation axis. Each forming unit comprising has a mold that defines a first and a second forming cavity and is formed by two half-mold parts, which can move with respect to each other to pass between an open position for feeding the preforms and for unloading the bottles and a closed position, in which it defines at least one forming cavity.
BLOW MOLD
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.
Apparatus for molding handle-equipped container, and mold and mold unit for use in same
An apparatus for molding a handle-equipped container is provided. The apparatus has a gripping mechanism section 160a which comprises a first gripping member 161 having a pair of first chuck members 163 for grasping a preform 200, and a second gripping member 162 having a pair of second chuck members 167 for grasping a container handle 20 in association with the action of the first gripping member 161. The apparatus can simultaneously grasp a plurality of the preforms 200 and a plurality of the container handles 20 and reliably transport them to a blow molding section.
PARISON SEPARATION DEVICE, BLOW MOLDING MACHINE, AND METHOD FOR MANUFACTURING BLOW-MOLDED ARTICLE
A parison separation device (30) according to an embodiment includes a cutter (31) with a cutting edge (35), the cutting edge (35) extending in a one direction and facing upward, and a block (33), the cutter being attached to an upper part of the block (33), inclined surfaces (37) being formed on both sides of the block (33) in a thickness direction of the cutting edge (35), each of the inclined surfaces (37) including a component that is inclined increasingly downward as it gets closer to one direction side end, in which the parison separation device (30) is disposed on a discharging direction side of a discharging port of a parison and configured to cut the parison discharged from the discharging port.
Resin container manufacturing device and manufacturing method
There is provided a resin container manufacturing apparatus configured to stretch a preform disposed in a stretch blow molding mold by a stretching rod and stretch the preform by introducing blow air into the preform so as to form a resin container. The resin container manufacturing apparatus includes detection means for detecting an actual position of the stretching rod inserted into the preform, and supply control means for controlling a supply state of the blow air based on a detection result of the detection means.
Parison guide
There is provided a parison guide which improves a flatness of parison with a simple configuration. A parison guide (1) guides a parison (P) which has an arc shape in horizontal cross section and is discharged from an extrusion apparatus (2). The parison guide is fixed to a discharge-side end portion of the extrusion apparatus (2). The parison guide includes a contact face (17) configured to come into contact with and guide an edge portion of the parison to flatten the parison. Preferably, the contact face (17) includes a curved surface, and the contact face (17) has a curvature of a horizontal cross section which gets smaller in a discharge direction.
Blow molding device
A blow molding device for blow molding preforms into a predetermined shape. The blow molding device includes a batch-type mold provided with cavities, a heating furnace that heats preforms while the preforms are arranged in series, a transfer machine that simultaneously transfers the preforms as a batch to the cavities of the mold after the preforms are heated and sent out sequentially from the heating furnace, and a pressurized liquid feeder that feeds pressurized liquid to the preforms after the preforms are arranged in all of the cavities of the mold and the mold is closed.
Device and method for transporting preforms in the region of a blow-molding machine
The invention relates to devices and to methods for transporting preforms in the region of a blow-molding machine, in particular a sorting device (10) for transporting preforms (20) composed of a thermoplastic material in the region of a blow-molding machine for the blow-molding of containers, comprising a transportation wheel (12), which has a plurality of accommodating recesses (18) for accommodating and conveying the preforms (20), which accommodating recesses are arranged on the circumference of the transportation wheel in such a way that the accommodating recesses are distributed in the circumferential direction, a guide collar (16), which extends circumferentially around the transportation wheel (12) in some regions in such a way that the guide collar is radially spaced apart from the transportation wheel, wherein the preforms (20) are transported in suspension between the transportation wheel (12) and the guide collar (16) in the region of the sorting device (10), and a selection unit for selectively removing a respective individual preform (20) transported in one of the accommodating recesses (18) of the transportation wheel (12), wherein the selection unit comprises a pivotable ejecting star (14) with a plurality of ejecting arms (31), which ejecting star, when in the idle position, reaches into the peripheral region of the transportation wheel (12) by means of a first ejecting arm (31) immediately adjacent to the guide collar (16) in the transportation direction of the preforms (20), in such a way that the preforms (20) in the accommodating recesses (18) that are transported past the first ejecting arm (31) are secured against unintentionally falling out, wherein the ejecting star (14), in the event of a rotational motion, pushes an individual preform (20), which is marked for removal, out of one of the accommodating recesses (18) of the transportation wheel (12) by means of a second ejecting arm (32) following after the first ejecting arm (31), and wherein, in a recurring manner after the preform (20) marked for removal has been pushed out, the second ejecting arm (31) takes on the securing of the preforms (20) transported past the second ejecting arm against falling out of the accommodating recesses (18).
