[0002] A cement pipe making machine, as the name suggests, is a machine for making cement pipes. It is also commonly known as cement pipe making machinery or cement pipe making equipment. In some parts of southern China, it is also called culvert machinery. Its main structure consists of two parts: the machine itself and the mold. Based on its structural form, it can be divided into roller-type pipe making machines and centrifugal pipe making machines. Concrete pipe molds are a component of roller-type pipe making machines.

[0003] The existing concrete pipe molds used in roller-type pipe making machines have weak structural strength and are prone to deformation under long-term pressure. They are also inconvenient for demolding. Therefore, there is an urgent need for a new type of concrete pipe mold for roller-type pipe making machines to solve the above technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A concrete pipe mold for a roller-type pipe making machine includes a mold, the inner wall of which is coated, and the outer wall of which is circumferentially arranged with six reinforcing ribs. A supporting cylinder is connected to the outer wall of the six reinforcing ribs. The space between the supporting cylinder and the mold is filled with filler material. An upper stabilizing mold body is provided at the upper end of the supporting cylinder, and a lower stabilizing mold body is provided at the lower end of the supporting cylinder. Five upper connecting ears are connected to the left and right sides of the upper stabilizing mold body, and five lower connecting ears are provided to the left and right sides of the lower stabilizing mold body. The upper and lower connecting ears are connected by fastening bolts and nuts.

[0007] As a preferred embodiment of this invention, the six reinforcing ribs are arranged in a ring at equal intervals on the outer side wall of the mold.

[0008] As a preferred embodiment of this utility model, the reinforcing rib is in the shape of a cuboid structure.

[0009] As a preferred technical solution of this utility model, the coating material is a polyurethane-graphene composite coating.

[0010] In a preferred embodiment of this invention, the filler material is polyurethane foam.

[0011] In a preferred embodiment of this utility model, the number of fastening bolts and nuts is set to ten.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model strengthens the structural strength of the concrete pipe mold by setting up a supporting cylinder, filling material and six reinforcing ribs, and by utilizing their mutual cooperation, effectively preventing deformation under pressure.

[0015] 2. This utility model provides a coating on the inner wall of the mold, and the coating material is a polyurethane-graphene composite coating. The polyurethane-graphene composite coating material can reduce the coefficient of friction, thereby reducing the demolding resistance and facilitating demolding. Attached Figure Description
