Abstract

The utility model relates to a making mould of a cement pipe, and aims at providing a making mould of cement pipes, which is easily assembled and located and prevents cement grout from leaking outside. The quality of the cement pipes is improved. According to the specific technical scheme of the utility model, the making mould of the cement pipes comprises two half moulds with semicircular sections, wherein the two half moulds are buckled together to form a hollow cylinder, grooves are formed in one half mould along the axial direction of two buckling connecting parts of the two half moulds, and bulges matched with the grooves are arranged on the other half mould along the axial direction of the two buckling connecting parts of the two half moulds. The making mould has the beneficial effects that the two semicircular half moulds are connected by adopting a convex-concave manner, thus the cement grout is effectively prevented from leaking outside; the grooves and the bulges can be used as locating devices also, and thus the assembly is convenient; and when the two half moulds are assembled in a use process, the assembly accuracy is improved, and the size accuracy and the specification uniformity of the cement pipes are greatly improved.

Description

Pipe of cement is made mould

Technical field

The utility model relates to a kind of concrete component machining tool, especially a kind of mould of making pipe of cement.

Background technology

In prior art, the mould of making pipe of cement commonly used comprises that two cross sections are the half module of semicircle, and two half modules snap together the cylinder that forms a hollow, and the fastening joint of two half modules is the plane on axially, and the two-half die that namely is commonly called as flushes.During use, cement is covered with the internal surface of column that two half modules form, because two-half die flushes, and the cement slurries that easily leak outside from the joint; On the other hand, because two-half die axial joint is the plane, so two-half die is when in use fastening, assembling inconvenience, and bad location easily causes the pipe of cement size inaccurate, and the specification deviation ratio is high.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and be easy to assemble the location, prevents the pipe of cement making mould that cement grout leaks outside, and promotes the pipe of cement product quality.

Concrete technical scheme of the present utility model is: a kind of pipe of cement is made mould, it comprises that two cross sections are the half module of semicircle, two half modules snap together the cylinder that forms a hollow, the fastening joint of two half modules, one of them half module fastens the joint at two and is provided with groove on axially, and another half module fastens the joint at two and is provided with the projection suitable with groove on axially.

As another kind of technical scheme, one of them half module is axially upper to be fastened the joint at two and is respectively arranged with groove and projection, and another half module axially go up and is fastened at two that the joint is provided with and last half module groove and protruding suitable projection and groove.

Described half module axial length is greater than 2 meters.

The beneficial effects of the utility model are: two semicircle half modules adopt concavo-convex joining, and have prevented effectively that namely cement grout from leaking outside; On the other hand, groove and projection can be used as again positioner, ease of assembly: when assembling, improve the assembling precision in the two-half die use procedure, greatly promote the degree of accuracy of cement tube product size and uniform specification.

The specific embodiment

As shown in the figure, a kind of pipe of cement is made mould, it comprises the half module 1 that two cross sections are semicircle, two half modules 1 snap together the cylinder that forms a hollow, the fastening joint of two half modules 1, one of them half module fastens the joint at two and is provided with groove 2 on axially, and another half module fastens the joint at two and is provided with the projection 3 suitable with groove on axially.

As another kind of technical scheme, one of them half module is axially upper to be fastened the joint at two and is respectively arranged with groove 2 and projection 3, and another half module axially go up and is fastened at two that the joint is provided with and last half module groove and protruding suitable projection 3 and groove 2.

Half module 1 axial length is greater than 2 meters.
