Detailed Description

The invention is further illustrated with reference to the following figures and examples:

example 1: a mold structure for preventing falling off and pulling out of pipes, which is shown in fig. 1 to 5.

Including two outer mould 1 and an interior mould 2, two outer mould 1 is right interior mould 2 carries out cladding and two outer mould 1 mutual lock, the left end of outer mould 1 is the semicircle arcuation, the right-hand member of outer mould 1 is the loudspeaker form, the left end outer mould 1's interior cambered surface is along controlling axis parallel and is equipped with a plurality of arcs 3, the upper and lower both ends of arc 3 are equipped with cooling tube 4 respectively, cooling tube 4 is followed outer mould 1's cambered surface sets up, the upper and lower both ends of arc 3 still are equipped with seal groove 5 respectively, the right-hand member outer mould 1's interior cambered surface is equipped with a plurality of sawtooth grooves 6, sawtooth groove 6 is along the right-hand member outer mould 1 sets up.

Wherein, the left end of interior mould 2 be tubulose with the left end of outer mould 1 matches, the right-hand member of interior mould 2 is the loudspeaker form, and the right-hand member 2 outside of interior mould still be equipped with the right-hand member sawtooth groove 6 assorted zigzag arch 7 on the outer mould 1, zigzag arch 7 is two outer mould 1 is right the card is gone into when interior mould 2 carries out the cladding in the sawtooth groove 6.

Wherein, the dorsal part of outer mould 1 still is equipped with sprue 8, sprue 8 with arc wall 3 intercommunication.

The corrugated pipe connection mode comprises two corrugated pipes which are produced by the anti-drop and anti-pull pipe die structure and are respectively a socket flared pipe 9 and a socket pipe 10, and further comprises a sawtooth-shaped sealing rubber ring 11, wherein the sawtooth-shaped sealing rubber ring 11 is installed between two wave crests of the socket pipe 10, and the socket pipe 10 which is provided with the sawtooth-shaped sealing rubber ring 11 is inserted into the socket flared pipe 9.

When the mold structure for the anti-drop and anti-pulling pipe is used, two outer molds 1 are mutually buckled on the outer side of an inner mold 2 through a sealing groove 5, then raw materials are injected into a forming cavity between the two outer molds 1 and the inner mold 2 through a filling port 8, cooling water is introduced through a cooling pipeline 4 on the outer mold 1 in the raw material forming process to circulate and cool so as to accelerate the forming of the raw materials in the forming cavity, and after the raw materials are formed, the two outer molds 1 are separated, and the inner mold 2 is pulled out and demolded to form the corrugated pipe.

When the corrugated pipe is constructed and connected, firstly, lubricating oil is coated on the sawtooth-shaped sealing rubber ring 11; then, installing the sawtooth-shaped sealing ring 11 between two wave crests of the spigot pipe 10, and then inserting the spigot pipe 10 together with the sawtooth-shaped sealing rubber ring 11 into the spigot and socket flaring pipe 10; it should be noted that the zigzag sealing rubber ring 11 must be mounted on the spigot pipe 10 in the manner shown in fig. 3, that is, the inclined direction of the saw teeth on the zigzag sealing rubber ring 11 is exactly opposite to the insertion direction of the spigot pipe 10, otherwise, the zigzag sealing rubber ring 11 can be damaged irreparably, N seals can be formed between the spigot pipe 10 and the spigot and spigot flared pipe 9 by the inserted zigzag sealing rubber ring 11 carrying N number of saw teeth, when water enters the inside of the pipe, the water pressure borne by the first saw tooth playing a sealing role is the largest, and the water pressure borne by the following saw teeth is decreased sequentially, so that the water pressure is decreased gradually due to the zigzag sealing, and the leakage of the water is avoided as much as possible.

In the above process, as shown in fig. 4, when the spigot tube 10 is inserted into the bottom of the socket flared tube 9, the saw teeth on the saw-tooth sealing rubber ring 11 are divided into two parts, most of the saw teeth are in close contact with the straight section on the socket flared tube 9 to play a role of sealing, and the rest of the saw teeth are located in the position of the saw-tooth-shaped inner cavity on the socket flared tube 9; when the spigot pipe 10 is forced to be separated from the socket flaring at the right end of the corrugated pipe under the action of external force, part of saw teeth on the sawtooth-shaped sealing rubber ring 11 are inlaid in a sawtooth-shaped groove on the socket flaring pipe 9 to form an anti-drop device, the spigot pipe 10 is firmly locked in the socket flaring pipe 9, and the larger the distance of mutual movement of the spigot pipe 10 and the socket flaring pipe 9 is; the more the saw teeth of the saw-tooth sealing rubber ring 11 enter the saw-tooth-shaped inner cavity, the greater the resistance to mutual separation between the pipes until the pipes cannot be separated from each other, and further, as shown in fig. 5, the saw-tooth-shaped protruding part arranged on the socket flared pipe 9 can not only form the saw-tooth-shaped inner cavity for preventing the socket flared pipe 9 and the spigot pipe 10 from being separated from each other, but also enhance the bearing strength of the socket flared pipe 9 and protect the inner saw-tooth sealing rubber ring 11 and the spigot pipe 10; the zigzag sealing rubber ring 11 can not deform in the socket flaring pipe 9, and the sealing effect can be kept for a long time.

The embodiments of the present invention are disclosed as the preferred embodiments, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention and make various extensions and changes without departing from the spirit of the present invention.
