Problems solved by technology

[0003] Carat tube has the advantages of corrosion resistance, light weight, easy installation, large flow rate and long life. It is an environmentally friendly green product and has gradually replaced high-energy materials such as cement, cast iron, ceramics, etc. During the production process, the outer coated single-wall corrugated pipe cannot be well bonded to the coated pipe, causing great inconvenience and waste, and there are potential safety hazards

Embodiment

[0027] Such as figure 1 As shown, a carat tube structure of this embodiment includes an outer winding tube cladding layer 1, an outer winding tube 2, an inner wall PE layer 3, an HDPE solid wall tube 4 and a pre-embedded heating wire 5 from the outside to the inside. The wrapping layer 1 of the winding pipe and the outer winding pipe 2 are covered by vacuum.

[0028] This embodiment adopts a kind of coating mold 6 that can enhance the bonding degree of the outer winding tube of the carat tube to realize the above-mentioned carat tube structure, such as figure 2 As shown, it includes an overmold main body 61 for cladding, a vacuum cylinder 62 and a vacuum pump 63. The vacuum cylinder 62 is fixed through the overmold main body 61, and the vacuum pump 63 is connected with the vacuum cylinder 62. During the cladding process, through Vacuumize, so that the outer winding pipe 2 and the cladding layer are tightly combined to enhance the hardness of the carat pipe; the main body of...

Abstract

The invention discloses a cladding mould capable of enhancing combination degree of an outer winding pipe of a krah pipe. The cladding mould comprises a cladding mould body for cladding, a vacuum cylinder and a vacuum pump, the vacuum cylinder is fixed in the cladding mould body in a penetrating mode, and the vacuum pump is connected with the vacuum cylinder. According to the cladding mould capable of enhancing combination degree of the outer winding pipe of the krah pipe, the vacuum cylinder and the vacuum pump are added so that the outer winding pipe is tightly combined with a cladding layer during cladding, and the hardness of the krah pipe can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of carat tubes, and in particular relates to a cladding mold and a carat tube structure capable of enhancing the bonding degree of the outer winding tube of the carat tube. Background technique [0002] The definition of polyethylene winding structure wall pipe is: a general term for thermoplastic round pipes made of polyethylene resin and made of winding molding technology for no internal pressure. Its characteristics are: 1. Strong chemical resistance Corrosion and erosion capabilities. 2. Good flexibility and strong impact resistance. 3. Cold resistance, aging resistance, simple connection, safe and reliable. 4. Light weight and convenient construction. 5. Strong wear resistance, service life of more than 50 years, and maintenance-free during the service life. 6. Excellent drainage performance, good sanitation, and can be recycled. The pipe is generally called a carat tube. Generally, a carat tube in...
