Problems solved by technology
[0002] Extruded pure plastic pipes have low cost performance, and it is difficult to make large-diameter pipes; extruded steel mesh reinforced plastic pressure pipes solve the problem of cost performance, but the diameter of the pipe is still small, and it is difficult to make large-diameter pipes
The existing patent literature also discloses the technology of making "large-diameter steel mesh reinforced plastic pressure pipe" by winding method, which is technically feasible, but there are still some problems, such as the pipe is wound and welded by prefabricated strips. The integrity is not very good; the inner wall is not very smooth, which increases the friction of water flow; the forming speed is slow, that is, the production efficiency is low

Embodiment Construction
[0031] Specific embodiments of the present invention, such as figure 1 As shown, an injection-molded steel mesh-reinforced plastic pressure pipe 1 has a steel mesh 3 wrapped inside the pipe wall, and an injection-molded pipe wall 4 is wrapped around the steel mesh 3 . The stencil 3 can be one layer, two layers, or even multiple layers. It can be a steel mesh composed of steel wires or a steel mesh layer rolled by plates and strips. The steel mesh has good reinforcement. On this basis, for the convenience of construction and connection, an integrally injection-molded flange 2 can be provided at both ends of the injection-molded steel mesh reinforced plastic pressure pipe. For the sealing performance of the connection between the pipe ends, one or both of them can be An annular groove for installing a sealing ring is arranged on the outer end face of each flange 2.

The invention discloses an injection molding type steel mesh reinforced plastic pressure pipe which is characterized in that wound steel meshes are arranged inside a pipe wall, and an injection-molded pipe wall is coated outside the steel meshes. The pressure pipe with the structure can be directly injected and molded by a mold, and the injected and molded pressure pipe has the following advantages of pipe injection molding and good integral performance, smooth and unseamed pipe inner wall, small flow frictional resistance, one-layer, two-layer or even multilayer steel mesh layout, good steel mesh strength, large pipe diameter, high production yield, and the like.
Description
technical field [0001] The invention relates to urban water supply facilities and its manufacturing method and processing mold, in particular to an injection-molded steel mesh reinforced plastic pressure pipe and its manufacturing method and processing mold. Background technique [0002] Extruded pure plastic pipes have low cost performance, and it is difficult to make large-diameter pipes; extruded steel mesh-reinforced plastic pressure pipes solve the problem of cost performance, but the pipe diameter is still small, and it is difficult to make large-diameter pipes. The existing patent literature also discloses the technology of making "large-diameter steel mesh reinforced plastic pressure pipe" by winding method, which is technically feasible, but there are still some problems, such as the pipe is wound and welded by prefabricated strips. The integrity is not very good; the inner wall is not very smooth, which increases the friction of water flow; the forming speed is slo...
