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： An apparatus for molding externally ribbed and corrugated thermoplastic pipes, including a pipe die for extruding a parison of a thermoplastic material; moldblock halves circulating in endless paths and cooperating with each other to form a travelling mold; and a means withstanding the hydraulic pressure of molding. The means is represented by yokes having shanks for engagement with complimentary recesses made in the halves. The yokes are provided with rollers guided in parallel paths ensuring that the shanks are driven toward and away from the recesses in a progressive motion without changing their orientation.

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： Double walled thermoplastic tubes, with corrugated outer walls and smooth inner wall are formed with integral bell sections spaced along the tube. The outer, corrugated wall is formed with a bell section. One of the walls is pierced between the ends of the bell section to allow the escape of air, and the inner wall is pressed outwards into engagement with the bell section of the outer wall.

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.
