Description
Technical Field
The utility model belongs to the technical field of pipe production, and particularly relates to a production mold for a double-layer axial hollow-wall pipe.
Background
Municipal administration rain sewage reposition of redundant personnel, drainage pipe reform transform engineering, sponge city construction are more and more, and are increasingly big to the demand of drainage tubular product. Compared with cement pipes, the double-layer axial hollow wall pipe has the obvious advantages of good connection sealing performance, corrosion resistance, convenience in transportation, quickness in construction, short construction period and the like, is suitable for municipal rainwater and pollution discharge engineering, hydraulic engineering, and engineering such as a pipe-replacing-canal and the like, and is also suitable for drainage of a building district and engineering such as a power pipe. The double-layer axial hollow-wall pipe is usually produced by extrusion molding, and the ring stiffness of the produced product cannot meet the requirement in the use process of the existing extrusion molding die, so that the structural strength is low, and the service life is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides the production mold for the double-layer axial hollow-wall pipe, which has the advantages of compact structure, high production efficiency and high production quality.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a production mould for double-deck axial cavity wall tubular product, including external mold and the coaxial centre form that sets up in the external mold, the external mold includes inlet pipe and integrative external mold pipe that sets up at the inlet pipe right-hand member portion, the centre form includes the spreader cone, form the feed inlet between spreader cone and the inlet pipe, the interior die body of a plurality of bars of even interval fixedly connected with of spreader cone right-hand member face outer fringe along the circumferencial direction, the top surface and the bottom surface of die body are on a parallel with external mold pipe and interior die pipe respectively in each bar, two sides of die body are perpendicular to external mold pipe and interior die pipe respectively in each bar, die body left end portion outer wall is respectively through outer connecting block and external mold pipe inner wall fixed connection in each bar, die body left end portion inner wall is respectively through inner connecting block fixed connection and has interior die pipe in each bar.
An inner-layer runner is arranged in the center of the shunting cone, an inner-layer runner cavity is communicated with the right end of the inner-layer runner, and a plurality of flow guide channels are connected to the outer edge of the inner-layer runner cavity at intervals along the circumferential direction.
And a plurality of connecting screws are fixedly connected between the outer wall of the feeding pipe and the outer wall of the shunting cone at intervals along the circumferential direction.
The inner wall of the left end of the feeding pipe is fixedly connected with a connector.
The left end of the connecting body is fixedly connected with a connecting disc.
By adopting the technical scheme, the double-layer axial hollow-wall pipe has the advantages of compact structure and high production efficiency, can be produced by only one processing procedure, avoids production of multiple composite procedures, and has high rigidity, high structural strength and long service life.
