Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing technology, specifically to a corrugated pipe processing apparatus and its processing technology. Background Technology

[0002] Corrugated pipes are mainly divided into two categories in terms of forming methods: plastic corrugated pipes and metal corrugated pipes. Plastic corrugated pipes are mostly made using extrusion molding processes. The mold is usually installed at the end of the extruder, and a specific mechanism is used to form a continuous corrugated structure from the molten plastic.

[0003] Chinese Patent No. CN221851015U discloses a corrugated pipe forming mold device. By providing an upper mold assembly, a lower mold assembly, and a central mold assembly, when it is necessary to cool the formed corrugated pipe, the water cooling assembly is turned on to draw cooling water into the central mold assembly, which can quickly cool the corrugated pipe on the outer wall of the central mold assembly. Then, the upper mold assembly is lifted upwards, which facilitates the demolding of the corrugated pipe. This solves the problem that when manufacturing short-distance corrugated pipes, it is difficult to quickly disassemble the mold and cool the corrugated pipe after injection molding, making it inconvenient to quickly remove the corrugated pipe.

[0004] However, the existing technology has the following drawbacks: it requires external equipment to lift the upper mold assembly, and then the formed corrugated pipe needs to be manually demolded from the lower mold assembly. Since the corrugated pipe is still stuck to the lower mold assembly, the demolding of the corrugated pipe is not convenient enough. In addition, during the injection molding process, air bubbles are easy to exist inside the injection plastic, which leads to defects such as voids inside the formed corrugated pipe, air bubbles or silver streaks on the surface, reducing the quality of the corrugated pipe. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background art by providing a bellows processing apparatus, comprising: The mold mechanism comprises two sets arranged opposite to each other. The mold mechanism includes an upper slide rail, a lower slide rail, a conveying section, a mold block, an inner mold tube, a sealing cover, and a venting block. The upper and lower slide rails are arranged facing each other and connected by a connecting plate. The conveying section is connected between the upper and lower slide rails. Multiple sets of mold blocks are provided and connected to the conveying section. The mold blocks are slidably connected to the upper and lower slide rails via sliders. The venting block is connected to the upper and lower ends of the mold block. The mold blocks between the two mold mechanisms close together to form the outer mold. The inner mold tube is located inside the outer mold and one end is connected to the outlet of the extruder. The sealing cover is threaded onto the inner mold tube to seal the outlet of the outer mold. The vibration mechanism includes a drive unit, rod a, nut block, rod b, plate a, and vibration block; multiple holes are provided on the side wall of the inner mold tube; rod a is rotatably located inside the inner mold tube; two sets of nut blocks are provided and threadedly connected to rod a; multiple rods b are provided and rotatably connected to the nut blocks; the other end of rod b is rotatably connected to plate a; the vibration block is located on plate a and slidably connected to the holes; the drive unit is detachably connected to rod a. A moving mechanism, which is connected to the drive unit to control the position of the drive unit.

[0006] Preferably, the conveying unit includes a motor a, a sprocket, and a chain; the sprocket is provided in two sets and is rotatably connected to the upper slide rail and the lower slide rail through a rotating shaft; the chain is meshed with the sprocket; the chain links on the chain are connected to the mold block; the motor a is located on the upper slide rail and is connected to the rotating shaft of one of the sprockets through a gearbox a.

[0007] Preferably, the inner mold tube is connected to an inlet pipe and an outlet pipe; the inlet pipe and the outlet pipe are respectively equipped with valve a and valve b.

[0008] Preferably, a telescopic component a is connected to the connecting plate; one end of the telescopic component a is connected to an arc-shaped block.

[0009] Preferably, the drive unit includes a motor b, a gearbox b, and an end cover; the motor b is connected to the end cover via the gearbox b; a slot is provided on the end face of the end cover; and a locking block that matches the slot is connected to one end of the rod a.

[0010] Preferably, the moving mechanism includes a base a, a base b, a carrier plate, a telescopic component b, and a telescopic component c; the base b is slidably disposed on the base a; the telescopic component b is disposed on the base a and connected to the base b; the carrier plate is slidably disposed on the base b; the telescopic component c is disposed on the base b and connected to the carrier plate; the motor b and the gearbox b are both disposed on the carrier plate.

[0011] The present invention also proposes a corrugated pipe processing technology, which uses the above-mentioned corrugated pipe processing device and includes the following steps: S1. Extrusion Injection Molding: First, the sealing cap is rotated to block the discharge port of the outer mold; then, the injection plastic is extruded into the molding cavity formed between the outer mold and the inner mold tube by the extruder. S2, Vibration and Exhaust: Motor b, in conjunction with gearbox b, drives the end cover to rotate intermittently in both directions. The end cover drives rod a to rotate intermittently in both directions, causing the nut blocks on both sides to move intermittently towards or in opposite directions. This causes the vibrating blocks to repeatedly vibrate the plastic injection in the mold, causing the air bubbles in the plastic injection to continuously accumulate and move upward, and finally be discharged through the vent block. S3, Cooling and Molding: Connect the external water pipe to the water inlet pipe; thereby injecting cold water into the inner mold tube. The cold water exchanges heat with the injection plastic through the inner mold tube. Every once in a while, the water in the inner mold tube is discharged through the water outlet pipe to replace the cold water, ensuring that the injection plastic can cool and form a corrugated pipe. S4. Demolding: First, the motor b, in conjunction with the gearbox b, causes the vibrating block to detach from the inner wall of the corrugated pipe, achieving initial demolding between the corrugated pipe and the inner mold tube. Then, the moving mechanism drives the end cap to separate from the inner mold tube. Afterward, the knob seals the cap to separate it from the outlet of the outer mold. The conveying unit drives the mold block to move, and the mold blocks on both sides will automatically separate when they reach the end of the conveying unit, achieving the demolding function of the outer mold. The movement of the mold block will drive the corrugated pipe to move, causing the inner wall of the corrugated pipe to separate from the inner mold tube, until the corrugated pipe is completely separated from the outer mold and the inner mold tube.

[0012] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: By incorporating a mold mechanism, the conveyor unit drives the movement of each mold block. When the mold blocks on both sides reach the end of the conveyor unit, they automatically separate, achieving the demolding function of the outer mold. The movement of the mold blocks drives the corrugated pipe to move, causing the inner wall of the corrugated pipe to separate from the inner mold tube, until the corrugated pipe is completely separated from the outer mold and the inner mold tube, thus achieving the automatic demolding function of the corrugated pipe without the need for other tools, reducing the difficulty of demolding. Furthermore, the mold blocks are equipped with multiple sets that can achieve automatic replacement. During the corrugated pipe injection molding process, the workers can clean the used mold blocks, eliminating the vacuum period caused by mold cleaning and improving the production efficiency of corrugated pipes.

[0013] By incorporating a vibration mechanism, a motor b, in conjunction with a gearbox b, drives a vibrating block to repeatedly vibrate the injected plastic, causing air bubbles in the injected plastic to continuously accumulate and rise, eventually being discharged through a venting block. This prevents air bubbles from existing inside the formed corrugated pipe, ensuring the forming quality of the corrugated pipe. Attached Figure Description

[0016] Example 1, as Figures 1-3 and Figures 6-8 As shown, the present invention proposes a corrugated pipe processing device, which includes a mold mechanism, a vibrating mechanism and a moving mechanism; The mold mechanism has two sets arranged opposite to each other; the mold mechanism includes an upper slide rail 1, a lower slide rail 18, a conveying part, a mold block 3, an inner mold tube 14, a sealing cover 23, and a vent block 2; the upper slide rail 1 and the lower slide rail 18 are arranged facing each other and connected by a connecting plate 5; the conveying part is connected between the upper slide rail 1 and the lower slide rail 18; the mold block 3 has multiple sets and is connected to the conveying part, and the mold block 3 is slidably connected to the upper slide rail 1 and the lower slide rail 18 through a slider 16 (the slider 16 is cylindrical and can rotate in the upper slide rail 1 or the lower slide rail 18, so as to...). (Adjust the angle of mold block 3); the vent block 2 is connected to the upper and lower ends of mold block 3 (the vent block 2 is made of ventilated steel; ventilated steel is a porous material made of powder sintering, containing a large number of micropores of about 10 micrometers inside, allowing air to pass through smoothly, while the injection plastic cannot pass through); the mold blocks 3 between the two mold mechanisms close together to form the outer mold; the inner mold tube 14 is located inside the outer mold and one end is connected to the discharge port of the extruder; the sealing cap 23 is threaded onto the inner mold tube 14 to seal the discharge port of the outer mold (refer to...). Figure 1The inner mold tube 14 is connected to a water inlet pipe 22 and a water outlet pipe 17. The water inlet pipe 22 and the water outlet pipe 17 are respectively equipped with valve a and valve b (valve a and valve b are electrically controlled valves). The connecting plate 5 is connected to a telescopic component a6. One end of the telescopic component a6 is connected to an arc-shaped block 8 (the telescopic component a6 includes, but is not limited to, devices such as cylinders. The telescopic component a6 drives the arc-shaped block 8 to move, so that the arc-shaped blocks 8 on both sides clamp one end of the inner mold tube 14, which serves to temporarily support the inner mold tube 14). The vibration mechanism includes a drive unit, rod a21, nut block 27, rod b28, plate a26, and vibration block 25; multiple holes are provided on the side wall of the inner mold tube 14; rod a21 is rotatably mounted inside the inner mold tube 14; two sets of nut blocks 27 are provided and threadedly connected to rod a21; multiple rods b28 are provided and rotatably connected to nut blocks 27; the other end of rod b28 is rotatably connected to plate a26; vibration block 25 is mounted on plate a26 and slidably connected to the holes (the surface of vibration block 25 and the inner wall of the holes are coated with nitrile rubber). Nitrile rubber is a commonly used and excellent material in sliding seals, with advantages such as wear resistance, oil resistance, and cost-effectiveness. The drive unit is detachably connected to rod a21. The drive unit includes motor b9, gearbox b, and end cover 19. Motor b9 is connected to end cover 19 via gearbox b. The end face of end cover 19 has a slot. One end of rod a21 is connected to a locking block 20 that matches the slot (the connection between end cover 19 and rod a21 is achieved by inserting locking block 20 into the slot, which facilitates the motor b9 cooperating with the gearbox to drive rod a21 to rotate). The moving mechanism is connected to the drive unit to control the position of the drive unit.

[0017] In this embodiment, the sealing cap 23 is first rotated to block the outlet of the outer mold. Then, the injection plastic is extruded into the molding cavity formed between the outer mold and the inner mold tube 14 using an extruder. During the injection plastic extrusion process, the motor b9, in conjunction with the gearbox b, drives the end cap 19 to rotate intermittently in both directions. The end cap 19 drives the rod a21 to rotate intermittently in both directions, causing the nut blocks 27 on both sides to move intermittently in opposite directions. This causes the vibrating block 25 to repeatedly vibrate the injection plastic in the mold, causing air bubbles in the injection plastic to continuously accumulate and move upwards. Finally, the air is discharged through the vent block 2, preventing air bubbles from existing inside the formed corrugated tube and ensuring the molding quality of the corrugated tube. Afterward, the external water pipe is connected to the water inlet pipe 22, thereby injecting cold water into the inner mold tube 14. The cold water exchanges heat with the injection plastic through the inner mold tube 14. Every once in a while, the water in the inner mold tube 14 is discharged through the water outlet pipe 17 to replace the cold water, ensuring that the injection plastic can cool and form a corrugated tube. Cooling and forming After the process is complete, motor b9, in conjunction with gearbox b, first disengages vibrating block 25 from the inner wall of the corrugated pipe (at this point, vibrating block 25 is not completely separated from the hole), achieving initial demolding between the corrugated pipe and the inner mold tube 14. Then, the moving mechanism drives end cap 19 to separate from the inner mold tube 14. Afterward, knob sealing cap 23 is turned to separate it from the outlet of the outer mold. The conveying unit drives mold block 3 to move, and the mold blocks 3 on both sides will automatically separate when they reach the end of the conveying unit, achieving the demolding function of the outer mold. The movement of mold block 3 will drive the corrugated pipe to move, causing the inner wall of the corrugated pipe to separate from the inner mold tube 14, until the corrugated pipe is completely separated from the outer mold and the inner mold tube 14, thereby achieving the automatic demolding function of the corrugated pipe without the need for other tools, reducing the demolding difficulty. In addition, the mold block 3 is equipped with multiple sets that can achieve automatic replacement. During the corrugated pipe injection molding process, the operator can clean the used mold block 3, eliminating the vacuum period caused by mold cleaning and improving the production efficiency of the corrugated pipe.

[0018] Example 2, as Figures 4-5 As shown, the bellows processing device proposed in this invention, compared with Embodiment 1, further includes a conveying section. The conveying section includes a motor a4, a sprocket 24, and a chain 15. The sprocket 24 is provided in two sets and is rotatably connected to the upper slide rail 1 and the lower slide rail 18 through a rotating shaft. The chain 15 is meshed with the sprocket 24. The chain links on the chain 15 are connected to the mold block 3. The motor a4 is provided on the upper slide rail 1 and is connected to the rotating shaft of one of the sprockets 24 through a gearbox a.

[0019] In this embodiment, motor a4, in conjunction with gearbox a, drives one of the sprockets 24 to rotate, which in turn drives chain 15 to rotate. The rotation of chain 15 drives each mold block 3 to move along the upper slide rail 1 and the lower slide rail 18, thereby realizing the replacement function of mold block 3.

[0020] Example 3, as Figure 6As shown, the bellows processing device proposed in this invention, compared with Embodiment 2, further includes a moving mechanism structure. The moving mechanism includes a base a7, a base b11, a carrier plate 10, a telescopic component b13, and a telescopic component c12. The base b11 is slidably disposed on the base a7; the telescopic component b13 is disposed on the base a7 and connected to the base b11; the carrier plate 10 is slidably disposed on the base b11; the telescopic component c12 is disposed on the base b11 and connected to the carrier plate 10; the motor b9 and the gearbox b are both disposed on the carrier plate 10.

[0021] In this embodiment, the carrier plate 10 is moved by the telescopic component c12, and the carrier plate 10 moves the motor b9 and the gearbox b, thereby moving the end cover 19 away from the rod a21. Then, the base b11 is moved by the telescopic component b13, so that the motor b9 and the gearbox b move laterally and are offset from the inner mold tube 14, which facilitates the demolding of the corrugated tube.

[0022] Example 4, please refer to Figures 1-8 The present invention also proposes a corrugated pipe processing technology, which uses the corrugated pipe processing apparatus described in any one of Embodiments 1 to 3 above, and includes the following steps: S1. Extrusion injection: First, the sealing cap 23 is rotated to block the discharge port of the outer mold; then, the injection plastic is extruded into the molding cavity formed between the outer mold and the inner mold tube 14 by the extruder. S2, Vibration and venting: The motor b9, in conjunction with the gearbox b, drives the end cover 19 to rotate intermittently in both directions. The end cover 19 drives the rod a21 to rotate intermittently in both directions, causing the nut blocks 27 on both sides to move intermittently in opposite directions. This causes the vibrating block 25 to repeatedly vibrate the plastic injection in the mold, causing the air bubbles in the plastic injection to continuously gather and move upward, and finally be discharged through the vent block 2. S3, Cooling and Molding: Connect the external water pipe to the water inlet pipe 22; thereby inject cold water into the inner mold tube 14. The cold water exchanges heat with the injection plastic through the inner mold tube 14. Every once in a while, drain the water in the inner mold tube 14 through the water outlet pipe 17 to replace the cold water and ensure that the injection plastic can cool and form a corrugated pipe. S4. Demolding: First, the motor b9, in conjunction with the gearbox b, causes the vibrating block 25 to detach from the inner wall of the corrugated pipe, achieving initial demolding between the corrugated pipe and the inner mold tube 14. Then, the moving mechanism drives the end cap 19 to separate from the inner mold tube 14. Afterward, the knob sealing cap 23 is turned to separate it from the outlet of the outer mold. The conveying part drives the mold block 3 to move. When the mold blocks 3 on both sides move to the end of the conveying part, they will automatically separate, achieving the demolding function of the outer mold. The movement of the mold block 3 will drive the corrugated pipe to move, causing the inner wall of the corrugated pipe to separate from the inner mold tube 14, until the corrugated pipe is completely separated from the outer mold and the inner mold tube 14.

[0023] In summary, the sealing cap 23 is first rotated to block the outlet of the outer mold. Then, the injection molding compound is extruded into the molding cavity formed between the outer mold and the inner mold tube 14 using an extruder. During the injection molding process, the motor b9, in conjunction with the gearbox b, drives the end cap 19 to rotate intermittently in both directions. The end cap 19 drives the rod a21 to rotate intermittently in both directions, causing the nut blocks 27 on both sides to move intermittently in opposite directions. This causes the vibrating block 25 to repeatedly vibrate the injection molding compound in the mold, causing air bubbles in the injection molding compound to continuously accumulate and rise. Finally, the air bubbles are discharged through the vent block 2, preventing air bubbles from existing inside the formed corrugated pipe and ensuring the quality of the corrugated pipe. Molding quality; then, connect the external water pipe to the inlet pipe 22; thereby injecting cold water into the inner mold tube 14, the cold water exchanges heat with the injection plastic through the inner mold tube 14, and every once in a while, drain the water in the inner mold tube 14 through the outlet pipe 17 to replace the cold water, ensuring that the injection plastic can cool and form a corrugated pipe; after cooling and molding, first use motor b9 in conjunction with gearbox b to make the vibrating block 25 detach from the inner wall of the corrugated pipe, realizing the initial demolding between the corrugated pipe and the inner mold tube 14; then use telescopic component c12 to drive the carrier plate 10 to move, the carrier plate 10 drives motor b9 and gearbox b to move, thereby driving the end cover 19 away from rod a2. 1. Then, the telescopic component b13 drives the base b11 to move, causing the motor b9 and gearbox b to move laterally and offset from the inner mold tube 14, facilitating the demolding of the corrugated pipe; then, the telescopic component a6 drives the arc block 8 away from the inner mold tube 14, and the knob sealing cover 23 separates it from the discharge port of the outer mold; the motor a4, in conjunction with the gearbox a, drives one of the sprockets 24 to rotate, which in turn drives the chain 15 to rotate. The rotation of the chain 15 drives each mold block 3 to move along the upper slide rail 1 and the lower slide rail 18, thereby moving the mold blocks 3. When the mold blocks 3 on both sides move to the end of the conveying section, they will automatically separate, realizing the demolding function of the outer mold. Yes; the movement of mold block 3 will drive the bellows to move, causing the inner wall of the bellows to separate from the inner mold tube 14 (since the inner wall of the bellows has already separated from the vibrating block, the contact area between the inner wall of the bellows and the inner mold tube 14 is reduced, reducing the difficulty of demolding), until the bellows is completely separated from the outer mold and the inner mold tube 14, thus realizing the automatic demolding function of the bellows without the need for other tools, reducing the difficulty of demolding. In addition, mold block 3 is equipped with multiple sets that can realize automatic replacement function. During the bellows injection molding process, the staff can clean the used mold block 3, eliminate the vacuum period caused by mold cleaning, and improve the production efficiency of bellows.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
