    摘要: A mold is provided for forming molded parts having flash seams which are moved to inconspicuous locations. The mold, which is typically used to make blow molded parts, includes two or more mold blocks and removable inserts which allow relocation of flash seams and at the same time allow removal of the finished part from the mold.

    摘要: The upper and lower halves of a blow mold define a blow mold cavity when the halves are closed together. A bottom plug which serves to form a dome in the bottom of the blown bottle is shifted into and out of a cooperating relationship with the two mold halves by cam mechanism that operates in response to raising and lowering of the upper die set upon which the upper mold half is mounted. The actuating mechanism comprises a pair of mutually opposed cam rods having a follower trapped therebetween that is in turn coupled with the bottom plug so that as the cam rods are shifted with the upper die set, the follower reacts to cam surfaces on the rods to impart a corresponding extension and retraction motion to the bottom plug. To handle multiple, side-by-side blow mold cavities, the bottom plugs for such cavities are ganged together on a common support bar that is in turn provided with operating shanks, each provided with a cam follower operated by a cam assembly. In an alternative embodiment, the bottom plug is split into two upper and lower halves, with each half being provided with its own actuating mechanism. Sets of upper plug halves can be ganged together for actuation in unison, as can sets of lower plug halves.

    摘要: A container is made in two stages from material such as thermoplastics that is deformable when heated. In the first stage a preform (1) is injection moulded, the mould parts easily releasing a tubular body (2) with a closed end. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, the blow pin being applied to the open end. The closed end of the body is stretched over a multi-part section (7, 8) of the mould which shapes the base of the container into an indent with an undercut formation, the cross section being generally omega-shaped. The multi-part mould section has a central tapered core (8) surrounded by an array of segments (7), the core (8) being fully inserted to spread the segments (7) for moulding, and being retracted to allow the segments (7) to close up and release the container after moulding. The divisions (12) between segments (7) produce ribs in the indent which provide added strength.

    摘要: The present invention provides a wholly blow molded light weight bumper system which provides a double walled vertical blow rib for mounting the bumper to a vehicle and a method for making the same. A first surface projects from one of the molds and is perpendicular to the first and second mold halves. In association with the first surface a second surface is movable between a retracted position and an extended position. To create the vertical rib the second surface is moved from the retracted position to the extended position. The second surface thereby pinching the inflated thermoplastic material between the first surface creating a double walled vertical rib substantially perpendicular to the parting line.
