Description

Technical Field

[0001] This utility model relates to a molding device, specifically a vacuum shaping and cooling molding device for PVC drainage pipes, belonging to the field of PVC pipe cooling molding technology. Background Technology

[0002] PVC drainage pipes are building drainage materials made primarily of polyvinyl chloride resin. They have advantages such as corrosion resistance, light weight, and low fluid resistance. The production process uses a vacuum shaping and cooling molding device, which uses negative pressure adsorption to tightly fit the molten pipe blank into the shaping mold, and then uses circulating cooling water to quickly solidify it, thereby ensuring accurate pipe dimensions and a smooth inner wall. They are widely used in drainage systems for civil and industrial buildings.

[0003] A search revealed a Chinese patent with publication number CN218196421U that discloses a VC-UH drainage pipe cooling molding process, including a molding machine and a cooling tank. A liquid storage tank is installed on the left side wall of the molding machine. A first liquid inlet pipe is connected to the front of the upper end of the liquid storage tank, and a first connecting pipe is connected to the rear of the upper end of the liquid storage tank. The first connecting pipe is connected to the molding machine. A collection box is installed at the front end of the molding machine, and a limit frame is installed at the rear end of the cooling tank.

[0004] While the above-mentioned solution can cool and shape the pipe, there is still room for improvement in practical applications. In the current device, during the circulating spraying process, dust and impurities falling off the surface of the pipe can easily clog the water outlet and affect the efficiency of the circulation system. In addition, long-term circulation can also cause the coolant temperature to rise continuously, reducing the shaping efficiency and thus making it less practical. To address these issues, we provide a vacuum shaping and cooling molding device for PVC drainage pipes. Utility Model Content

[0028] This utility model provides a vacuum shaping and cooling molding device for PVC drainage pipes.

[0029] Example 1:

[0030] Please see Figure 1 , Figure 2 and Figure 3It includes a vacuum chamber 1, and an integrated power control box is mounted on the outer surface of the vacuum chamber 1. The power control box is electrically connected to the municipal power supply through wires, thereby ensuring that the electrical equipment in this application is powered normally.

[0031] The vacuum chamber 1 is equipped with a partition plate 2 and a negative pressure component 3. The outer surfaces of the partition plate 2 and the negative pressure component 3 are fixedly connected to the vacuum chamber 1. The negative pressure component 3 is composed of a shaping tube and a vacuum pump. The outer surface of the vacuum chamber 1 is hinged with a sealing cover, which can seal the outlet tube of the shaping tube. A vacuum groove is opened on the surface of the shaping tube. The vacuum pump in the negative pressure component 3 evacuates the shaping tube through the vacuum groove to form a negative pressure inside the shaping tube, which can better shape the tube.

[0032] The vacuum chamber 1 is equipped with a forming mechanism 4, which includes a first filter plate 401 and a second filter plate 402. The outer surfaces of the first filter plate 401 and the second filter plate 402 are fixedly connected to the partition plate 2.

A rotary motor is fixedly installed inside the vacuum chamber 1. The output end of the rotary motor is fixedly connected to the reciprocating screw 403. A reciprocating groove is opened on the outer surface of the reciprocating screw 403. A limiting slide rod that matches the reciprocating groove on the surface of the reciprocating screw 403 is rotatably connected to the inner wall of the cleaning plate 405. Through the setting of the reciprocating groove and the limiting slide rod, the reciprocating slip ring 404 can be driven to reciprocate and slide in the inner wall of the vacuum chamber 1 when the reciprocating screw 403 is driven to rotate.

[0034] Example 2:

[0035] Please refer to it again. Figure 1 , Figure 2 and Figure 3 Two sprockets 406 are rotatably connected to the outer surface of the vacuum chamber 1. A chain 407 is connected between the two sprockets 406. By setting the chain 407, when an external motor drives one sprocket 406 to rotate, it can drive the other sprocket 406 to rotate synchronously.

[0036] The inner wall of the vacuum chamber 1 is rotatably connected to an auger cleaning roller 408. One end of the auger cleaning roller 408 is fixedly connected to a sprocket 406. A dirt collection tank is fixedly installed on the outer surface of the vacuum chamber 1. This allows the reciprocating screw 403 to not only scrape and clean the surface of the filter plate 402 during rotation to prevent impurities from clogging, but also to evenly push solid impurities to the dirt collection tank on the surface of the vacuum chamber 1 for centralized storage.

[0037] A delivery pipe 409 is fixedly connected to the inner wall of the vacuum box 1. The outer surface of the delivery pipe 409 is fixedly connected to the partition plate 2. A nozzle 410 is fixedly connected to the outer surface of the delivery pipe 409. The vacuum box 1 and the partition plate 2 effectively fix the delivery pipe 409, making the nozzle 410 more stable during water spraying.

[0038] A water pump 411 is fixedly connected to the inner bottom wall of the vacuum chamber 1. The output end of the water pump 411 is fixedly connected to the delivery pipe 409. The control button of the water pump 411 is integrated on the outer surface of the vacuum chamber 1. The water pump 411 can be started and stopped by the control button.

[0039] Example 3:

[0040] Please refer to it again. Figure 1 , Figure 2 and Figure 4 The vacuum chamber 1 is equipped with a cooling mechanism 5, which includes a cooling pipe 501. The outer surface of the cooling pipe 501 is fixedly connected to the vacuum chamber 1 through a fixing plate. Both ends of the cooling pipe 501 pass through the vacuum chamber 1 and are fixedly connected to the vacuum chamber 1. A fixing plate is fixedly installed on the inner wall of the vacuum chamber 1. The inner wall of the fixing plate is fixedly connected to the cooling pipe 501. The fixing plate effectively supports and limits the cooling pipe 501.

[0041] A liquid pump 502 and a cooling device 503 are fixedly connected to the outer surface of the vacuum chamber 1. The output end of the liquid pump 502 is fixedly connected to the cooling pipe 501, and the input end of the cooling device 503 is fixedly connected to the cooling pipe 501. A circulation pipe 504 is fixedly connected to the output end of the cooling device 503. The end of the circulation pipe 504 away from the cooling device 503 is fixedly connected to the input end of the liquid pump 502. By turning on the liquid pump 502 and the cooling device 503, the coolant in the cooling pipe 501 can be continuously cooled and circulated within the cooling pipe 501, effectively recooling the filtered water. This ensures that the water remains cooled during the circulating spraying process, effectively avoiding the problem of excessively high water temperature affecting the cooling and forming efficiency of the pipe due to long-term use.

[0042] The water pump 411, liquid pump 502 and cooling device 503 in this application are all common electrical devices in the prior art. This application will not elaborate on their models and internal structures. They can also be replaced by other power sources.

[0043] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0044] In use, this invention works as follows: First, the tubing is introduced into the shaping tube of the negative pressure assembly 3 through an extrusion device. Then, the vacuum pump in the negative pressure assembly 3 evacuates the shaping tube to create a negative pressure. Simultaneously, the water pump 411 is started to draw water from inside the vacuum chamber 1 into the delivery pipe 409, and then sprays it out from the nozzle 410 onto the shaping tube to cool the tubing inside. The sprayed water will come into contact with the filter plate 401, effectively performing the first filtration of the used water. At the same time, the reciprocating screw 403 and the auger cleaning roller 408 are driven. The rotation of the reciprocating screw 403 drives the reciprocating slip ring 404 to slide back and forth inside the vacuum chamber 1. The reciprocating slip ring 404 drives the cleaning plate 405 to move back and forth on the top surface of the filter plate 401, effectively scraping and cleaning the filtered solid impurities to both sides inside the vacuum chamber 1. Then, the filter plate 402 performs a second filtration. During the filtration process, the reciprocating screw 403 not only scrapes and cleans the surface of the filter plate 402 to prevent impurities from clogging it, but also evenly pushes solid impurities to the collection tank on the surface of the vacuum chamber 1 for centralized storage. This ensures that the water remains pure during circulation, effectively preventing impurities from clogging the nozzle 410, greatly improving cooling efficiency and uniformity, reducing resource waste, lowering equipment maintenance frequency, and saving operating costs. Secondly, by simultaneously turning on the liquid pump 502 and the cooling device 503, the coolant in the cooling pipe 501 is continuously cooled and circulated within the cooling pipe 501, effectively recooling the filtered water. This keeps the water in a cooled state during the circulating spraying process, effectively preventing the problem of excessively high water temperature affecting the cooling and forming efficiency of the pipe due to long-term use, further enhancing the practicality of this device.
