Abstract

A mold for a spigot or a muzzle bell of an HDPE hollow wall winding pipe comprises a lower mold body horizontally arranged on the ground. A mold core is arranged above the lower mold body in the horizontal direction. An upper mold body is arranged above the mold core. The mold is characterized in that a lower semicircular groove is formed in the lower mold body; an upper semicircular groove is formed in the upper mold body; and a round hole matched with the mold core is formed by the lower semicircular groove and the upper semicircular groove. The shape of the bottom of a steel jacket ring at the muzzle bell end is restrained through a cylinder on a locating support, the shape of the middle portion of the steel jacket ring at the muzzle bell end is adjusted by rotating locating screws on locating holes, and therefore the connecting forming precision of the hollow wall winding pipe is greatly guaranteed.

Description

technical field [0001] The invention relates to the field of hollow-wall winding pipe sockets, in particular to a mold for the socket or socket of HDPE hollow-wall winding pipes. Background technique [0002] At present, the hollow-wall winding pipes produced continuously by enterprises are straight and do not have sockets or sockets. As a result, heat-shrinkable sleeves or electric heating belts can only be used to connect during the construction process. The construction is complicated and the cost is high. Contents of the invention [0003] The technical scheme that the present invention adopts for solving the problems of the technologies described above is: [0004] A mold for the socket or socket of HDPE hollow wall winding pipe, comprising a lower mold horizontally arranged on the ground, a mold core is arranged horizontally above the lower mold, an upper mold is arranged above the mold core, the The lower mold is provided with a lower semicircular groove, the upper...
