Core mold vibration process flexible joint steel bell and spigot jacking pipe mold

Abstract

The invention relates to molds, in particular to a core mold vibration process flexible joint steel bell and spigot jacking pipe mold. The core mold vibration process flexible joint steel bell and spigot jacking pipe mold comprises a bell mouth molding ring, a spigot molding ring and a spigot chassis; the spigot molding ring is detachably connected with the spigot chassis, the outer edge of the spigot molding ring and the outer edge of the spigot chassis are each provided with a ring of outward flange side, the flange sides of the spigot molding ring and the spigot chassis are each provided with at least eight evenly-distributed taper pin holes, the taper pin holes of the spigot molding ring and the spigot chassis are in one-to-one correspondence, taper pins are arranged in the corresponding taper pin holes, and the end faces of the taper pins do not protrude out of the free end faces of the flange sides; three radial pin holes are formed in the spigot molding ring, and the three radial pin holes correspond to pressure test water injection holes in a water draining pipe spigot required to be casted; according to the mold, demolding is easy, and the molding effect of a casted pipe is good.

Description

Technical field [0001] The invention relates to a mold, in particular to the technical field of manufacturing a forming mold for a jacking pipe socket socket. Background technique [0002] Jacking construction is to use a jack to dig and push the components to the required position. This construction method is only used when it is inconvenient to excavate. [0003] The drainage pipe for jacking construction is made of concrete. Its two sections are the socket and the socket. When casting, the socket forming mold and the socket forming mold are required. The socket forming mold is composed of an integrated socket forming ring and a socket chassis. In the demolding process of this kind of socket forming mold, demoulding is difficult and easy to produce inclination error; in the casting process, this kind of socket forming mold cannot guarantee the concentricity of the socket. [0004] The jacking-in drain pipe generally has three pressure test inlet holes on the circumference of the ...
