Embodiment 1

[0021] like figure 1 Shown, be a kind of embodiment of synchronous double-deck steel wire mold of the present invention, it comprises the most important three parts: die opening 1, tapered sleeve 2 and wooden mold mouth 9, cooperate to form the whole mold between these three parts structure, wherein, the left end of the die mouth 1 has a tapered groove, the radial dimension of the tapered groove gradually decreases from the outside to the inside, and the tapered sleeve 2 is inserted into the inside of the tapered groove. Of course, the tapered sleeve 2 and the tapered The grooves are not completely fitted, but there is a certain gap, that is, figure 1 The first feeding chamber 3 in the middle, the overall shape of the first feeding chamber 3 is also conical, and is used for the flow of the first layer of material of the hose.

[0022] There is a cylindrical groove at the center of the die mouth 1, and the centerline of the cylindrical groove coincides with the centerline of t...

Embodiment 2

[0028] This example uses figure 1 The hose produced by the synchronous double-layer steel wire mold shown is a double-layer structure with spring steel wires embedded in the double-layer structure, and the double-layer structure is made of different materials and formed at one time. It has high strength, and the double-layer structure basically does not appear delamination, which can meet the different needs of different occasions.

Abstract

The invention provides a synchronous dual-layer steel wire mold and a hose produced through the mold. The problems that in the prior art, operation of producing a dual-layer hose is complex, the production cost is high, and the phenomenon of delaminating is prone to happening to products are solved. The synchronous dual-layer steel wire mold comprises a mold opening. A conic groove is formed in one end of the mold opening, and the radial size of the conic groove is gradually reduced from outside to inside. A conic sleeve with the shape matched with the shape of the conic groove is arranged inthe conic groove. A conic first feeding cavity is formed between the outer wall of the conic sleeve and the inner wall of the conic groove. A cylindrical groove is formed in the center position of themold opening. The center line of the cylindrical groove coincides with that of the conic groove. A core shaft is arranged in the cylindrical groove. An annular combination cavity is formed between the outer wall of the core shaft and the inner wall of the cylindrical groove. The tail end of the first feeding cavity communicates with the starting end of the combination cavity. A feeding opening isfurther arranged at the other end of the mold opening, an annular feeding groove communicating with the feeding opening is further arranged in the mold opening, and the annular feeding groove communicates with the combination cavity through a second feeding cavity.

Description

technical field [0001] The invention relates to the technical field of hose production, in particular to a synchronous double-layer steel wire mold with simple structure and convenient use and the hose produced by the mold. Background technique [0002] Hose is an important part in modern industry. It is mainly used to transport various fluids or as a protective layer to protect equipment such as wires and cables. Common hoses are usually made of galvanized steel strips, stainless steel strips, PA, PE, PP Made of other plastic materials. [0003] The common hoses in the prior art are usually of single-layer structure, but with the continuous development of the industrial level, people have put forward higher and higher requirements for the hoses, for example, in some special working conditions, the strength of the hose, Indexes such as wear resistance and corrosion resistance will directly determine the service life of the hose. Therefore, there are also double-layer hoses ...
