Problems solved by technology

Since the inner and outer hardness of the telescopic hose connector formed by one-time injection molding is consistent, not only the inner wall has no concave-convex structure, but also cannot meet the needs of inner hardness and outer softness

Embodiment 1

[0029] For the telescopic hose with a special-shaped ring connector in this embodiment, see figure 2 , image 3 , with a hose body 5 embedded with a spiral steel wire, one end of the hose body is embedded with a hard plastic lining 2, and the soft plastic joint 3 is wrapped outside to form a connecting head. The outer circle of hard plastic liner 2 has spiral guiding rib 2-1 (referring to Figure 5 ), the inner hole has a concavo-convex structure that plays a role in guiding and positioning the connecting piece—the axial ribs 2-3 distributed at intervals, and one end extends out of the hook 2-2. The end of the hose main body 5 is stretched and twisted on the hard plastic liner 2 . The soft plastic joint 5 is ring-shaped, and outside the end of the hose main body 5 with the hard plastic lining 2 embedded in the tight hoop, the hose main body 5 and the hard plastic lining 2 become an integral body tightly fitted after injection molding.

Abstract

The invention relates to an extensible hose with a special-shaped lining-ring connector, and a molding method thereof, belonging to the technical field of rubber and plastic hoses. The hose is provided with a hose body into which spiral steel wires are embedded, the inside of one end of the hose body is inlaid with a hard plastic lining ring, and the outside of the hose body is cladded with a soft plastic connector, thereby forming a connector; the excircle of the hard plastic lining ring is provided with a spiral guiding rib, and an inner hole is provided with a concave-convex structure; and an end head of the hose body is drawn and spirally buckled on the hard plastic lining ring; the soft plastic connector is in the shape of a ring, and tightly hooped on the outside of the end head of the hose body in which the hard plastic lining ring is inlaid, and the soft plastic connector, the hose body and the hard plastic lining ring are formed into a closely bonding whole. The extensible hose with a special-shaped lining-ring connector provided by the invention is provided with a guiding-positioning concave-convex structure, and hard outside and soft inside, therefore, the supporting demands of new products can be satisfied; meanwhile, the hose provided by the invention also breaks the rules, and through process innovation, the manufacturing of the extensible hose with a special-shaped lining-ring connector is feasible and practical.

Description

technical field [0001] The invention relates to a telescopic hose, in particular to a telescopic hose with a joint of a special-shaped lining, and also relates to an injection molding method formulated for the particularity of the special-shaped lining, belonging to the technical field of rubber and plastic hoses. Background technique [0002] For a long time, telescopic hoses with connectors have been formed by one-time injection molding, and the process is as follows: [0003] 1) Straighten one end of the plastic telescopic hose and clamp it on the inner supporting mandrel; [0004] 2) Position the inner support mandrel, put the plastic hose inserted with the inner support mandrel into the matching injection mold; [0005] 3) Injection molding makes the end of the telescopic hose form a connecting head firmly covering it. [0006] With the needs of product function development, when some telescopic hoses are connected with adjacent parts, the inner wall of the joint head...
