[0034] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0035] like Figures 1 to 9B The high-speed washing pipe forming machine 1 is suitable for preparing automobile washing pipes 2.

Therefore, by adjusting the number of molding modules 21 and the number of mold segments 222, automobile washing pipes 2 of different lengths can be quickly prepared, which is convenient for disassembly and meets the customization requirements of the pipe 2.

[0036] There are multiple vacuum blocks 223, each of which is installed on each of the mold segments 222, so that the chamber body 221 can be fully vacuumed, which makes it easier for the tube wall of the tube 2 to be adsorbed on the inner wall 216 of the molding module 21, so that the tube 2 can be quickly molded.

[0037] The molding mechanism 20 is provided with a tube inlet 201 and a tube outlet 202, the mold segment 222 includes a tube inlet section 227, a tube outlet section 228 and a plurality of molding sections 229, the molding sections 229 are detachably arranged continuously between the tube inlet section 227 and the tube outlet section 228, the tube inlet 201 is formed at the tube inlet section 227, the diameter of the tube inlet 201 is gradually reduced from the outside to the inside, the tube outlet 202 is formed at the tube outlet section 228, the diameter of the tube outlet 202 is gradually expanded from the inside to the outside, and the tube inlet 201 is aligned with the extruder head. Therefore, it is convenient for the pipe 2 to enter the molding section 229 from the tube inlet 201 for vacuum molding, and then be transported out at the tube outlet 202.

[0038] Among them, the first conveying track 225 and the second conveying track 226 are symmetrical rounded rectangular structures, and the rounded rectangular structure is a connecting structure with arcs at both ends and a middle rectangle, which is convenient for the circular rotation of the first module half 211 and the second module half 212. The first module half 211 is detachably mounted on the first conveying track 225, and the second module half 212 is detachably mounted on the second conveying track 226. The driving mechanism 30 drives the first conveying track 225 and the second conveying track 226 to operate synchronously, so that the first module half 211 and the second module half 212 are synchronously connected and pass through the forming section 229, which is convenient for forming the pipe fitting 2.

[0039] The first module half body 211 and the second module half body 212 are respectively provided with a sub-cavity 213, and the sub-cavity 213 is formed in the axial direction of the molding module 21, and the sub-cavities 213 are connected to form the mold cavity 210, and the inner wall 216 structure of the sub-cavity 213 is adapted to the tube wall molding of the pipe fitting 2, and the diameter of the mold cavity 210 is adapted to the pipe fitting 2, such as Fig. 9A and 9B shown.

[0040] The molding module 21 further includes a joint portion 214 and a protrusion 215. The joint portion 214 is a tooth-shaped structure. The joint portion 214 is arranged at the lower end of the molding module 21. The joint portion 214 of the first module half body 211 is engaged with the first conveying track 225, and the joint portion 214 of the second module half body 212 is engaged with the second conveying track 226, so that the first module half body 211 and the second module half body 212 can be synchronously cyclically rotated, so that the first module half body 211 and the second module half body 212 are in a closed state and a separated state. When the molding module 21 is in a closed state, the pipe 2 is placed in the mold cavity 210 formed by the first module half body 211 and the second module half body 212 being connected to each other. When the pipe 2 After molding, the first module half body 211 and the second module half body 212 are separated from their respective first conveying tracks 225 and the second conveying tracks 226 for operation, that is, during the movement from the tube inlet section 227 to the tube outlet section 228, the first module half body 211 and the second module half body 212 are in a closed state, and during the movement from the tube outlet section 228 to the tube inlet section 227, the first module half body 211 and the second module half body 212 are in a separated state, so that the molding module 21 can be operated in a continuous cycle, and according to the different customization requirements of the length of the pipe 2, different numbers of the mold 22 molding sections 229 and the corresponding molding modules 21 can be arranged to meet the preparation requirements of customers, such as 300 pairs of molding modules 21.

[0042] The mold 22 further includes a circulating water circuit 224, which is connected to each of the molding sections 229, so that cooling water can be passed into the first conveying track 225 and the second conveying track 226, so as to cool down the first module half body 211 and the second module half body 212. If the temperature of the molding module 21 rises too much during operation, it will affect the molding effect, making the molding effect of the pipe 2 worse. At the same time, the separation of the first module half body 211 and the second module half body 212 is also helpful for cooling. When the first module half body 211 and the second module half body 212 clamp the pipe 2 from the pipe inlet 201 to the pipe outlet 202, the temperature of the molding module 21 rises. When the first module half body 211 and the second module half body 212 move from the pipe outlet 202 to the pipe inlet 201, the outward circulation rotation is also helpful for cooling down the molding module 21.

[0044] The molding mechanism 20 further includes an upper cover 24, each of which is detachably mounted on each of the mold segments 222 to cover the mold segments 222.

[0045] The frame 10 further includes a lifter 11, a linear guide 12, a separation cylinder 13 and a movable frame 14. The movable frame 14 is movably installed on the upper part of the frame 10. The lifter 11 is vertically connected to the movable frame 14 so that the movable frame 14 can be lifted and lowered. The linear guide 12 is laterally installed on the movable frame 14. The support frame 23 is slidably connected to the linear guide 12 of the movable frame 14. The limit cylinder 232 is connected to the movable frame 14 so as to push the movable frame 14 to move longitudinally. The separation cylinder 13 is connected to the support frame 23 so as to push the support frame 23 to move laterally along the linear guide 12, so that the mold 22 is close to or away from the extrusion port of the pipe fitting 2, so that the high-speed washing pipe forming machine 1 and the extruder are close to or separated.

[0046] The driving mechanism 30 includes a gear box 31, a servo motor 32, a reducer 33 and a sprocket 34. The gear box 31 is connected to the sprocket 34, and the sprocket 34 drives the first conveying track 225 and the second conveying track 226 to operate. The gear box 31 is a three-tooth synchronous gear box 31, which can drive the three sprockets 34 to rotate synchronously.

[0047] An application method of a high-speed washing pipe forming machine 1, suitable for preparing an automobile washing pipe 2, comprises the steps of:

[0048] S100: continuously arranging the forming section 229 of the mold 22 between the pipe inlet section 227 and the pipe outlet section 228;

[0049] S200 places the first module half 211 into the first conveying track 225, and the second module half 212 into the second conveying track 226, wherein the first module half 211 and the second module half 212 are axially symmetrically placed on the first conveying track 225 and the second conveying track 226 respectively, so that the first module half 211 and the second module half 212 are connected to form a mold cavity 210.

The first module half body 211 and the second module half body 212 relatively surround the pipe 2, so that the pipe 2 is clamped in the mold cavity 210 of the molding module 21. With the synchronous operation of the first conveying track 225 and the second conveying track 226, each of the first and second conveying tracks 225 and 226 is driven by the first conveying track 225 and the second conveying track 226. The first module half body 211 and the second module half body 212 continuously surround the pipe fitting 2 relative to each other, and the pipe wall of the pipe fitting 2 is subjected to the vacuum effect in the chamber body 221. The internal pressure of the pipe fitting 2 is greater than the external pressure of the chamber body 221, so that the pipe wall of the pipe fitting 2 is tightly adsorbed on the inner wall 216 of the mold cavity 210, which facilitates the rapid molding of the pipe fitting 2 until the molding module 21 brings the pipe fitting 2 to the pipe outlet 202, and the first module half body 211 and the second module half body 212 are separated toward each other, and the pipe fitting 2 is prepared from a round tube into a corrugated automobile washing pipe 2.
