Description

Technical Field

[0001] The utility model relates to a die for an underground cable conduit, in particular to a flaring limiting device at the tail of the die for an underground cable conduit. Background Art

[0002] The underground cable conduit is formed and fixed by a plurality of conduit arrays and installed underground, and communication cables and the like pass through the conduits.

[0003] In the die for an underground cable conduit, a plurality of conduits need to be placed in the cavity, and then cement is filled in the cavity. After molding, the underground cable conduit is demolded from the die.

[0004] When the conduits are placed in the cavity, the conduits need to be fixed. The conventional fixing of the conduits is positioned through a connecting plate, but such a positioning method is not stable enough. The buoyancy of the cement filled in the cavity will cause the conduits to displace, resulting in the change of the positions of the conduits after demolding, which affects the coaxiality when a plurality of conduits are axially arranged.

[0005] In summary, how to realize the positioning of the end of the conduit in the cavity has become an urgent problem to be solved by researchers in this field. Summary of the Utility Model

[0009] In this solution, first, a plurality of positioning parts are correspondingly passed through the mother board, and then the limiting rod horizontally penetrates through a plurality of connecting ribs. The connecting ribs abut against the backs of the positioning parts, and the positioning parts are limited between the limiting rod and the mother board. At this time, the flaring parts of the positioning parts are placed in the cavity for the ends of the conduits to be inserted. At this time, the ends of the conduits are flared and deformed, so as to realize the positioning of the ends of the conduits in the cavity.

[0010] After molding is completed, the limiting rod is separated from the connecting ribs, and the top part is axially pulled out.

[0011] To illustrate the specific structure of the mold body, the present utility model adopts that the mold body includes a surrounding wall forming a cavity, a bottom plate, a female plate, and a male plate; wherein, the surrounding walls are provided on both sides; the rear ends of the two surrounding walls are detachably connected to the female plate; the front ends of the two surrounding walls are detachably connected to the male plate;

[0012] In this solution, the mold body is formed by detachably connecting a bottom plate, surrounding walls on both sides, and female and male plates at the front and rear ends. After molding, the female plate, male plate, two surrounding walls, and the bottom plate are separated to achieve demolding after molding.

[0013] To achieve the axial positioning of multiple underground cable ducts after molding, the present utility model adopts that a trapezoidal protrusion is convexly provided on one side of the female plate located inside the cavity; a trapezoidal groove is concavely provided on one side of the male plate located inside the cavity;

[0014] In this solution, one end of the underground cable duct after molding has a trapezoidal groove, and the other end has a trapezoidal protrusion. The trapezoidal groove and the trapezoidal protrusion are matched to play a role in axial positioning.

[0015] To illustrate the specific structure of the positioning part, the present utility model adopts that the positioning part includes: a limiting ring axially arranged in sequence, which abuts against the surface of the female plate; an insertion part, which passes through a through hole opened on the female plate, wherein the outer diameter of the insertion part matches the inner diameter of the female plate; the flaring part, which is a frustum structure and is adapted to allow the end of the duct to pass through;

[0016] The function of the limiting ring is to limit the axial displacement of the positioning part. The insertion part plays a sealing role to prevent cement from overflowing from the gap. The function of the flaring part is to allow the end of the duct to be inserted, causing the duct to undergo flaring deformation and perform positioning.

[0017] To facilitate different specifications of the flaring part, the present utility model adopts that a holding part is further provided on the outer side of the limiting ring; the holding part abuts against the limiting rod;

[0018] In this solution, the purpose of replacing the positioning part is to replace different specifications of the flaring part to meet different specifications of ducts. During the process of replacing the positioning part, the positioning part can be replaced by holding the holding part.

[0019] The beneficial effects of the present utility model: The present utility model is a tail flaring limiting device for an underground cable duct mold. First, multiple positioning parts are correspondingly passed through the female plate, and then the limiting rod is horizontally passed through multiple connecting ribs.
