摘要： A mold block which is used in a moving mold tunnel comprises first and second mold block sections which meet at their parting faces to close the mold block. Each mold block section has a product shaping interior surface and an air movement passage having an entrance at the base of each mold block section, a first opening to the interior surface and a second opening to the parting face of each mold block section. An air flow controller is provided between the parting face opening and the interior surface opening of the passage in the first mold block section and an air flow controller is provided between the entrance and the interior surface opening in the passage in the second mold block section. Through various different positionings of the two air flow controllers, the mold block can be operated in any one of four different modes including a first vacuum forming mode in which air is withdrawn from the mold block through both of the mold block sections, a second vacuum forming mode in which air is withdrawn from the mold block through only one of the mold block sections, a third cooling mode in which air is introduced into the mold block through one of the mold block sections and is then withdrawn from the other of the mold block sections and a fourth blow molding mode in which pressure within the mold block is released through both mold block sections.

摘要： An apparatus for forming a thermoplastic pipe having a profiled surface includes a nozzle having an extrusion orifice feeding extrudate in a downstream direction to a mold path which extends from the nozzle and along which are provided a first mold block and a second mold block downstream of the first mold block. The mold blocks are closable around the extrudate to form the pipe and are openable to release the pipe. The mold blocks are moved together with one another and with the pipe in the downstream direction when the mold blocks are closed and are opened and sequentially moved in an upstream direction along an axis contiguous with the axis of the mold path while the extrudate continues to move in the downstream direction. The first mold block is moved in the upstream direction before the second mold block such that the mold blocks never pass one another on the mold path. After the mold blocks are moved in the upstream direction, they are then reclosed around the extrudate at a position to maintain consistency of the profile of the pipe.

摘要： The invention concerns apparatus for molding thermoplastic tubing having solid annular ribs. The apparatus is of the type where a tubular mold is defined by cooperatively interengaged mold block of a pair of mold assemblies. An annular extrusion orifice for the tube extends into the mold tunnel and tubing is extruded about a mandrel. The invention provides an accumulator chamber in the region of the extrusion nozzle to provide for pressure differences which build up at that point. Thus, the effective volume of the accumulator chamber can compensate for the varying requirement for the thermoplastic material resulting from the varying radial wall thickness.

摘要： A pipe perforating apparatus has a spindle carrying a cutting tool and a drive for rotating the spindle about its own axis while revolving the spindle about the pipe. The cutter periodically engages and perforates the pipe. To provide for small, uniform sized holes in the pipe, the cutting tool is an end cutting punch and the spindle is rotated and revolved around the pipe to roll the punch into and out of the pipe without exerting a tangential force on the pipe.

摘要： Apparatus for producing corrugated thermoplastic tubing of the type comprising a pair of complementary upper and lower mold assemblies each having an endless chain of articulately interconnected mold blocks which are driven along a forward run and back along a return run, the mold blocks cooperating in pairs along the forward run to form an axially extending tubular mold tunnel, within which the tubing is expanded by vacuum forming or blow molding. The mold blocks have mold-defining faces of corrugated form with alternating troughs and crests. Each mold block is formed with passages which extend between the bases of the troughs of the corrugations and the exterior of the mold block. These passages communicate with the base of each trough throughout its length, and serve to permit the escape of any atmospheric air which is trapped by the tubing in the troughs during expansion of the tubing.

摘要： The invention provides a die assembly comprising a nozzle and at least one mandrel which defines with the nozzle an annular die orifice. The nozzle has a longitudinally extending stem terminating in the sleeve, the mandrel being located coaxially within the sleeve and coupled to the stem of the nozzle by an axially extending screw threaded coupling. The mandrel includes an internal flow passage having an inlet positioned to receive thermoplastic material from a supply passage extending along the nozzle and an outlet positioned to deliver the material to an annular distribution chamber defined by the opposing surfaces of the mandrel and the sleeve. The distribution chamber provides an uninterrupted annular flow path extending from the outlet to the die orifice, thereby avoiding the disadvantage of imperfect material distribution. For the production of multiple-walled tubing, a plurality of die stages coupled together in coaxial relationships are provided, the die components being so coupled by axially extending screw threaded couplings so positioned as not to interfere with the flow of plastic materials.
