Description

Technical Field

[0001] This utility model relates to the field of polyurethane pipe joint forming molds, specifically a polyurethane pipe joint forming mold with a cooling mechanism. Background Technology

[0002] Polyurethane pipe fittings are connection components made of high-quality polyurethane material and are widely used in petroleum, chemical, and water conservancy industries. They possess excellent wear resistance, corrosion resistance, and sealing performance, effectively reducing the risk of leakage in pipeline systems. Simultaneously, polyurethane pipe fittings also exhibit good flexibility and impact resistance, adapting to various complex working conditions, extending the service life of pipeline systems, reducing maintenance costs, and ensuring safe and reliable fluid transportation.

[0003] In the existing technology, polyurethane pipe joints are produced using molding molds. The molding molds are usually equipped with water channels as cooling mechanisms, through which coolant can flow. After prolonged use, a lot of rust and sludge will remain in the water channels, which will seriously affect the cooling effect of the device.

[0004] However, the water channels on the molding die are usually built directly inside the molding die, making it extremely troublesome for personnel to clean the water channels. Personnel need to disassemble the molding die and put it into a cleaning machine for cleaning. The molding die is heavy and requires the use of special tools for transportation, making the operation extremely troublesome and inconvenient for personnel to maintain later. Utility Model Content

[0024] Example 1

[0025] Please see Figures 1-4 This utility model provides a technical solution: a polyurethane pipe joint forming mold with a cooling mechanism, comprising: a lower forming mold 1, wherein an upper heat-conducting copper plate 12 and a contact copper plate 13 are provided on the lower forming mold 1; an mounting block 11 is provided on the upper heat-conducting copper plate 12, and a lower heat-conducting copper plate 10 is secured by the mounting block 11; a copper water pipe 9 is provided on the lower heat-conducting copper plate 10, and one end of the copper water pipe 9 is connected to a return water hose 14 through a connector 8; a metal water tank 3, wherein a cooling fan 5 and a water pump 6 are provided on the metal water tank 3, and the water pump 6 is connected to the connector 8 at one end of the copper water pipe 9 through a water supply hose 7;

[0026] In practical use, the lower heat-conducting copper plate 10 and copper water pipe 9 on the device can be disassembled and placed into an ultrasonic cleaner for separate cleaning, which facilitates the later maintenance of the device by personnel.

[0027] Example 2

[0028] Based on Embodiment 1, a metal water tank 3 is provided to improve the performance of the device. A water pump 6 is fixedly installed on the metal water tank 3. The water inlet pipe of the water pump 6 extends into the metal water tank 3. A water supply hose 7 is fixedly installed on the water outlet pipe of the water pump 6. The water supply hose 7 is connected to the connector 8 at the other end of the copper water pipe 9. By starting the water pump 6, the coolant in the metal water tank 3 is drawn out and discharged into the copper water pipe 9 through the water supply hose 7. The copper water pipe 9 dissipates heat to the lower heat-conducting copper plate 10.

[0029] A return water hose 14 is fixedly installed on the metal water tank 3. The other end of the return water hose 14 is connected to the connector 8 fixedly installed on the copper water pipe 9. The coolant finally flows into the metal water tank 3 through the return water hose 14.

[0030] The lower forming mold 1 is fixedly installed on the base 2. A metal water tank 3 is fixedly installed on the side of the base 2. Several water tank heat dissipation plates 4 are fixedly connected to the metal water tank 3. The water tank heat dissipation plates 4 are square plate-shaped structures. The water tank heat dissipation plates 4 are in contact with the back of the cooling fan 5. The cooling fan 5 is fixedly installed on the metal water tank 3. The water tank heat dissipation plates 4 and the cooling fan 5 work together to dissipate the coolant in the metal water tank 3. The above cycle realizes the heat dissipation operation of the forming mold.

[0031] An upper heat-conducting copper plate 12 is fixedly installed on the lower forming mold 1. The upper heat-conducting copper plate 12 has a square plate structure. Several contact copper plates 13 are fixedly connected to the upper heat-conducting copper plate 12. The contact copper plates 13 have a square plate structure and are all stuck inside the lower forming mold 1. Copper has a high thermal conductivity. By setting the contact copper plates 13, the contact area with the lower forming mold 1 is increased, and the heat dissipation effect is improved. Heat is conducted through the contact copper plates 13 and the upper heat-conducting copper plate 12. The upper heat-conducting copper plate 12 is in contact with the lower heat-conducting copper plate 10. The above combination achieves the cooling operation.

[0032] Example 3

[0033] Based on Embodiment 2, a base 2 is provided to improve the reliability of the cooling device. A limiting plate 19 is fixedly connected to the base 2. The limiting plate 19 has an "L" shaped plate structure. The threaded hole on the limiting plate 19 is threadedly connected to the adjusting bolt 20. A limiting post 18 is fixedly connected to the adjusting bolt 20. The limiting post 18 can be inserted into the slot 16 on the connecting plate 15. The connecting plate 15 is fixedly connected to the lower heat-conducting copper plate 10. The limiting post 18 has a cylindrical structure, the slot 16 has a circular groove structure, and the connecting plate 15 has a square plate structure. The limiting plate 19 limits and positions the connecting plate 15 to prevent the lower heat-conducting copper plate 10 from continuing to slide. Personnel can rotate the adjusting bolt 20 to make the limiting post 18 disengage from the slot 16 on the connecting plate 15.

[0034] Mounting blocks 11 are fixedly connected to both sides of the upper heat-conducting copper plate 12. The mounting blocks 11 have an "L"-shaped plate structure. The mounting blocks 11 cooperate with the upper heat-conducting copper plate 12 to hold the lower heat-conducting copper plate 10. The lower heat-conducting copper plate 10 has an "I"-shaped plate structure. A copper water pipe 9 is fixedly connected to the lower heat-conducting copper plate 10. A handle 17 is fixedly installed on the lower heat-conducting copper plate 10. By rotating the connector 8, the water supply hose 7 and the return hose 14 are no longer connected to the connector 8. Then, the personnel can pull the handle 17 to make the lower heat-conducting copper plate 10 slide out along the mounting block 11. The personnel can then put the lower heat-conducting copper plate 10 and the copper water pipe 9 into the ultrasonic cleaner for separate cleaning, so that the impurities attached to the copper water pipe 9 are cleaned off, ensuring the effectiveness of the device and facilitating later maintenance.

[0035] In actual use, the lower forming mold 1 is heated by contact copper plate 13, upper heat-conducting copper plate 12, and lower heat-conducting copper plate 10. Water pump 6, together with water supply hose 7, metal water tank 3, and return water hose 14, circulates the coolant in copper water pipe 9. The coolant flowing in copper water pipe 9 carries away the heat on the lower heat-conducting copper plate 10. The cooling fan 5 dissipates heat from the metal water tank 3 and its internal coolant, thus cooling the lower forming mold 1. The lower heat-conducting copper plate 10 and copper water pipe 9 can be disassembled for cleaning. Personnel can place the lower heat-conducting copper plate 10 and copper water pipe 9 into an ultrasonic cleaner for cleaning. The lower heat-conducting copper plate 10 and copper water pipe 9 are relatively light, which, combined with the above, makes the cleaning of copper water pipe 9 effective, ensuring the cooling effect of the device. It is not necessary to disassemble the entire forming mold for cleaning, which facilitates personnel's later maintenance.
