Abstract: An injection stretch blow molding apparatus and method wherein while the preforms are amply cooled the injection molding cycle time is shortened and furthermore a small number of blow cavities are used. In an injection molding section, N (N.gtoreq.2) preforms are injection molded in an upright state and then released from the injection cavity mold. While the preforms are cooled by the injection core mold, they are carried to a preform ejecting section. After the preforms cool to a temperature at which they can be ejected, the preforms are ejected from the injection core mold. In a transfer station, an array pitch of the simultaneously molded preforms are changed to a blow molding pitch, and then the preforms are transferred to a blow molding station in an inverted state. In the blow molding station, each preform is carried by a carrier member through a heating section into a blow molding section. In the blow molding section, n bottles are simultaneously blow molded from n preforms.

Abstract: An injection stretch blow molding apparatus and method wherein while the preforms are amply cooled the injection molding cycle time is shortened and furthermore a small number of blow cavities are used and the operation rate of these blow cavities is increased. In an injection molding section, N (N.gtoreq.2) preforms are injection molded and then released from the injection cavity mold at a relatively high mold-release temperature. While the preforms are cooled by the injection core mold, they are carried to a preform ejecting section. After the preforms cool to a temperature at which they can be ejected, the preforms are ejected from the injection core mold. In a transfer station, n (1.ltoreq.n<N) of the simultaneously molded N preforms at a time are transferred to a blow molding station in (N/n) transfer operations. In the blow molding station, each preform is carried by a carrier member through a heating section and a standby section into a blow molding section.

Abstract: An injection molding apparatus for a preform is disclosed, having an injection molding station (14) and a cooling and ejection station (16). In the injection molding station (14), neck cavity molds (60), injection core molds (50) and an injection cavity mold (42) are clamped and preforms (1) are injection molded. Thereafter, the injection cavity mold (42) is separated at a relatively high temperature. The preforms (1) are transferred to the cooling and ejection station (16) while being cooled by the injection core molds (50) and neck cavity molds (60). While the next preforms (1) are being injection molded in the injection molding station (14), in the cooling and ejection station (16) cooling of the preforms (1) continues. After cooling the preforms (1) to a temperature suitable for release, the injection core molds (50) are separated only through a stroke sufficient to allow a space to open between core pins (52) of the injection core molds 50 and the inner surface of the preforms (1).

Abstract: An injection molding apparatus in which a hot-runner mold is moved with respect to the injection nozzle of an injection unit is disclosed. In a position in which the injection nozzle comes into contact is provided a first fixed link with a runner formed therein. A second fixed link with a runner formed therein is fixed to the hot-runner mold, and moves integrally with the hot-runner mold. Between these links is provided an intermediate runner block system, with runners formed therein. The intermediate runner block system is constructed from a first intermediate link supported rotatably by the first fixed link and a second intermediate link supported rotatably by the second fixed link, and these two intermediate links are also rotatably coupled together. This plurality of links forms a link construction, so that regardless of the movement of the hot-runner mold the resin path between the injection nozzle and the hot-runner mold is maintained.

Abstract: An injection stretch blow molding method sequentially circulates a plurality of neck mold moving units for supporting and conveying neck molds adapted to hold the neck portions of hollow containers and preforms used to mold the hollow containers at least through preform injection molding, blow molding and ejecting stations, the preform injection molding step, the blow molding step for blow molding the hollow containers from the preforms having their potential heat provided by the injection molding step and the product ejecting step being repeatedly carried out. The injection molding stations of M in number are provided for blow molding stations of N in number (M>N.gtoreq.1). Preforms are injection molded in each of the injection molding stations at an injection molding start time staggered from those of the other injection molding stations by time equal to N.times.T/M where T is an injection molding cycle time in each of the injection molding stations.

A front chamber and a rear chamber of the clamping cylinder, divided by the piston section of the clamping ram, and a front chamber of the support cylinder are connected by an oil path. There is provided a valve for opening or closing the connection between the rear chamber of the clamping cylinder and the front chamber of the clamping cylinder and the front chamber of the support cylinder.

Abstract: A rear fork for motorcycles swingably supported at its front end portion from a body frame and supporting at its rear end portion a rear wheel axle, is built-up by interconnecting a plurality of constituent elements. The interconnection between the respective constituent elements is effected in a mutually fitted relationship with an adhesive agent interposed between their fitting surfaces, and if necessary, it is preferable to employ at the connecting portion reinforcing connection means such as rivets.

Abstract: A body frame of a small-sized vehicle such as a motorcycle or the like is assembled by interconnecting a plurality of frame elements. Among at least one pair of the frame elements, a connecting portion of one frame element is fitted into a connecting portion of the other frame element, and the respective connecting portions are firmly connected with each other by means of an adhesive agent. Moreover, the cross-section shapes of the both connecting portions are made non-circular, that is, not a simple circular shape, and thereby the interconnecting structure is very strong and rigid against a torsional force exerted thereupon.

After assembly and finishing of the frame, the resin is set simultaneously with the baking on of the finish.

Abstract: Disclosed is an improved wheel for a vehicle of the type having an annular rim adapted to carry a tire thereon and a wheel center, the annular rim being press fitted onto the outer peripheral part of said wheel center, the improvement consisting in that the annular rim and the wheel center are connected to one another with the aid of a layer of adhesive agent which is distributed in such a manner that its thickness assumes the maximum value at the central part of the cross-sectional configuration and decreases toward both the side edge parts of the wheel in the transverse direction. The maximum thickness of the layer of adhesive agent is determined in the range of 0.05 to 0.5 mm. The annular rim is firmly connected to the outer peripheral part of the wheel center by means of the layer of adhesive agent without any necessity for welding or the like operation so that the wheel has a good appearance. Epoxy resin based adhesive agent is preferably used for the wheel.
