Problems solved by technology

At present, the integral processing of the mold for producing square single-wall corrugation is difficult to process, the vacuum channel is narrow, and the appearance quality of the produced product is poor. Therefore, it is necessary to design a new mold with low processing cost, stable vacuum setting, and fast cooling.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] like figure 2 and image 3 Shown is the structural form of the square single-wall corrugated pipe forming die of the present invention. A split mold structure is adopted, a square hole 1a is milled out on the mold body 1, and a semi-circular groove 1b is turned out (see Figure 4 ) and then use the pressing block 3 to process the finished ring 2 (see Figure 5 ) is press-fitted in the semi-circular groove 1b of the mold body 1 to form the shape of a square single-wall bellows. Compared with the current monolithic structure, this split structure has simpler processing technology and shorter production period, and is suitable for mass production. A vacuum channel is processed on the mold body 1, and a vacuum groove is opened on the insert ring 2 to form a vacuum system. The vacuum system of this mold is easy to implement, the vacuum channel has a large space, and ...

Abstract

The invention relates to a forming mold of a square single-wall corrugated pipe. A split type mold structure is adopted; a square hole 1a is milled on a mold body 1; a semicircular groove 1b is formed; then a processed inlaying ring 2 is pressed in the semicircular groove 1b of the mold body 1 by using a pressing block 3; and finally the shape of the square single-wall corrugated pipe is formed. Compared with the existing integral structure, the split type structure is simpler in processing technology and shorter in production period, and is suitable for batch production. A vacuum passage, a sealing device and an open type water pouring cooling passage are further arranged on the mold body 1, so that vacuum shaping and cooling of the square single-wall corrugated pipe are realized. The forming mold in such structure is good in vacuum shaping and quick in cooling speed; the produced square single-wall corrugated pipe is stable in each performance, good in exterior quality and low in energy consumption; and the production cost is saved.

Description

technical field [0001] The invention relates to a corrugated pipe forming die, in particular to a square single-wall corrugated pipe forming die. Background technique [0002] With the continuous advancement of urbanization in our country, the demand for buried high-voltage cables used in cities continues to increase. As a protective tube for buried high-voltage cables, square single-wall corrugated pipes are not only temperature-resistant, pressure-resistant, waterproof, and anti-aging , It can also lay multiple cables in a concentrated manner, reducing land occupation and saving construction costs. The square single-wall corrugated pipe is suitable for the concentrated laying of multiple groups of pipelines, with close contact between the pipes, strong pressure resistance, small excavation space, simple construction operation, and considerable economic benefits. At present, the integral processing of the mold for producing square single-wall corrugation is difficult, the ...
