    The invention can be used in the chemical industry. The purpose of the invention is to eliminate high loads and wear in the working area of the apparatus. The apparatus comprises a tubular head for extruding a shell of plastic material, a semi-compression mold circulating along an endless path and interacting with each other to form a movable mold, and means for receiving the hydraulic pressure of the molding. Said means are sets of forks having shafts for engagement with matched cavities in semi-compression molds. The forks are provided with rollers directed in parallel tracks for translational movement of the shanks towards and away from the cavities without changing the orientation. During operation, the hydraulic pressure of the melt, which seeks to separate the semi-compression molds, is perceived by forks, coupled with cavities in the working section. Due to this, in the working area of the apparatus, high loads and wear of parts are eliminated. 2 hp ff, 4 ill.

    The invention relates to apparatus dp forming thermoplastic pipes, ribbed or corrugated outside, and can be used in the chemical industry.
    The purpose of the invention is to eliminate high loads and wear in the working section of the apparatus, as well as to ensure the entry of liners into the cavities without mutual cutting and to ensure the progressive movement of liners.
    On fig.L depicts the apparatus, made according to the invention, view
    from the side; figure 2 - sets of circulating plugs in an enlarged plan; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1.
    The apparatus for forming finned tubes on base 1 contains two lines of semi-compression molds 2, set in motion and mounted with the possibility of circulation through endless paths by means of asterisks 3, hooked with roller fingers 4 of semi-compression molds 2. The paths have a straight working 5, returnable 6 sections and two semi-circular guide tracks: 7 and 8 for transferring semi-press molds 2

    between sections 5 and 6. The semi-molds 2 are adjacent to each other in sections 5 and 6 and interact with those of the opposite line in section 5, in the direction of their hrcrCl and perpendicular to it, thus forming a mobile form for the resulting thermoplastic pipe, coming from the extrusion tubing head. 9, for extruding a thermoplastic sheath,
    The apparatus contains means for perceiving the working section 5 in both directions of interaction of the semi-compression molds 2 of the hydraulic pressure of the molding, made in the form of two infinite: sets 10, 11 forks 12 mounted with the possibility of circulation along the movable form. The sets 10, 11 of the forks 12 are located in the working section 5, and the forks have shanks 13 for entering the movable form into the mating cavities 14 made in the semi-compression forms 2. The forks 12 are equipped with rollers 15, and the sets 10, 11 are provided with y1 by them. They have an initial 1 end 17, a work 18 and a return 19 section, and sections 16 and 17 are provided with separate parallel directions by tracks 20 and 21.
    Sections 16-19 are intended to direct the rollers 15 with the ability to move in the initial 16 and final 17 sections of the shanks 13 progressively towards and away from the cavities J4 without changing the orientation. The shanks 13 can be conical or 1 cylindrical, can belong to semi-compression molds 2, in this case the mating cavities are made in forks, the initial and / or end sections can be equipped with rotor transfers (shown as asterisks 18, 22 in figure 4) kits may be chains and -, etc.
    When the apparatus is in operation, the extrudate 23 of thermoplastic material flows from the head 9 into a mobile form. The hydraulic pressure of the melt, which tends to separate the semi-press mold 2 in the working section 5, is perceived by forks 12, coupled with the cavities 14 in the working section 18. At the same time, no forces are transferred beyond the semi-press forms 2. The tracks 20 and 21 direct the shanks 13 in on

    the initial and final sections 16 and 17, respectively, in such a way that they move progressively without changing the orientation. This avoids the mutual use of the shanks 13 and the cavities 14.
    Thus, the guides are unloaded from the pressure by means of forks 12 fixing the semi-press-mold 2 to each other, i.e. hydraulic pressure is valid only in the area of the semi-compression mold - plug-semi-compression mold. The hydraulic pressure sensing tool consists of two infinite sets of circulating plugs 12, having 13 day shanks of approach along the specified moving form into the adjoining cavities 14. The forks 12 perceive the pressure in both indicated directions.
    Although the apparatus is mainly designed for the production of finned tubes outside (the process is close to injection molding), in rare cases it can be used to perceive air pressure when the latter is formed of extremely large tubes.
