Description

Technical Field

[0001] This utility model relates to the technical field of pumping devices, and in particular to an external circulating water pumping device. Background Technology

[0002] The external circulation pumping process of the mold is an important part of the cooling system. Its main function is to remove the heat generated by the mold during the production process by circulating cooling water, so as to ensure that the working temperature is kept within a suitable range, thereby improving production efficiency and product quality.

[0003] like Figure 7 As shown, an external circulation cooling system typically consists of a water supply tank, a circulation pump, a cooler, and various pipes. The cooling liquid circulates between the cooler and various pipes through the pumping action of the circulation pump, carrying away the heat generated during processing. Among them, the circulation pump, as the power component of the external circulation cooling system, is unable to generate sufficient pressure difference to drive the liquid flow in a high-temperature and high-pressure working environment. This leads to a sharp drop in pumping efficiency and even failure to work normally. At the same time, unreasonable design of the inlet and outlet mechanisms makes it impossible to maintain the continuous pumping of the system under high pressure, often resulting in pumping interruptions or excessive pressure fluctuations.

[0046] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0047] This utility model relates to an external circulating water pumping device, such as... Figures 1 to 7 As shown, it includes:

[0048] The base 1 is independently fixed and provides basic support for the entire device, and a support frame 2 is provided on the base 1;

[0049] The pump body 3, which is installed in the fixing hole of the support frame 2, is the core component of the entire device, and the pump body 3 is equipped with a mounting part 4 at one end;

[0050] The diaphragm 5 is installed at the connection between the pump body 3 and the mounting part 4. Due to its plasticity, the diaphragm 5 deforms according to the internal pressure change of the pump body 3 to realize the continuous pumping of circulating water.

[0051] Assembly 6 is installed at the other end of pump body 3, and water inlet mechanism 7 and water outlet mechanism 8 are respectively installed at water inlet and water outlet of assembly 6;

[0052] The water inlet mechanism 7 is connected to the circulation pipe of the external water supply tank, and is used to draw water from the circulation pipe of the external water supply tank to maintain the internal pressure balance of the pump body 3 when the internal pressure of the pump body 3 decreases.

[0053] The water outlet mechanism 8 is connected to the cooling pipe of the mold and is used to drain water into the cooling pipe to cool down and maintain the internal pressure balance of the pump body 3 when the internal pressure increases.

[0054] Drive mechanism 9, mounted on mounting part 4, is used to generate a pressure difference inside pump body 3;

[0055] The working principle of this device is as follows:

[0056] When the equipment is started, the drive mechanism 9 begins to operate, generating the necessary pressure difference inside the pump body 3. This pressure difference is achieved by the drive mechanism 9 applying force to the diaphragm 5, causing the diaphragm 5 to deform according to the pressure change inside the pump body and expand outward from the pump body 3. As the pressure inside the pump body 3 decreases, the water inlet mechanism 7 automatically opens, and external liquid enters the pump body 3 through the water inlet hole. As the liquid continues to flow into the pump body 3, the internal pressure balance of the pump body 3 is maintained. When the drive mechanism 9 pressurizes the pump body 3 in the opposite direction, the diaphragm 5 contracts inward from the pump body 3 due to the increased pressure. At this time, the water outlet mechanism 8 opens, and the liquid is discharged through the water outlet hole to achieve the internal pressure balance of the pump body 3. Through the continuous repetition of the above water intake and drainage process, continuous pumping of liquid is achieved.

[0057] The design of base 1 and support frame 2 provides a solid foundation, ensuring the stability and reliability of the entire device under different working environments. The design of pump body 3 and diaphragm 5 not only achieves efficient liquid pumping, but also adapts to different pressure changes through the deformation of diaphragm 5, improving the flexibility and adaptability of the system. The design of assembly 6 provides stable water inlet and outlet channels. The design of water inlet mechanism 7 and water outlet mechanism 8 ensures continuous pumping of the system. The design of drive mechanism 9 not only provides the necessary power source, but also achieves efficient liquid pumping by controlling the pressure difference. This design greatly simplifies the installation work, making the installation and disassembly of the equipment more convenient and quick, further improving the practicality and operability of the system, and ensuring the efficient operation and long-term stability of the external circulating water pumping device in various application scenarios.

[0058] As a preferred option, such as Figures 1 to 5 As shown, the water inlet mechanism 7 includes:

[0059] The mounting pipe 71 is installed at the water inlet of the assembly 6, and the mounting pipe 71 is also provided with an installation port and a water inlet.

[0062] The seal 75 is installed on the first spring 74, and the seal 75 is installed in conjunction with the barrier 72.

[0063] The design of the mounting pipe 71 and the baffle 72 ensures that the liquid is effectively guided and controlled when entering the pump body 3. The design of the mounting cover 73 and the first spring 74 not only provides a sealing function, but also realizes an automatic opening and closing function through the elasticity of the spring, improving the flexibility and adaptability of the system. The design of the seal 75 not only ensures the sealing of the inlet, but also can be quickly opened when needed to achieve efficient water intake. When the internal pressure of the pump body 3 decreases, the seal 75 contacts and separates from the baffle 72, and at this time the circulating water enters the interior of the pump body 3. When the internal pressure of the pump body 3 increases, the seal 75 and the baffle 72 fit tightly together, driving the circulating water to flow to the outlet, realizing the continuous pumping of circulating water.

[0064] As a preferred option, such as Figures 1 to 3 As shown, the water outlet mechanism 8 includes:

[0065] A connecting pipe 81 is installed at the outlet of assembly 6, and an outlet pipe 82 is provided on the connecting pipe 81.

[0066] The limiting member 83 is disposed inside the connecting pipe 81, and the limiting member 83 is located at the middle position between the water outlet pipe 82 and the water outlet of the assembly 6.

[0067] The assembly cover 84 is disposed in the groove of the connecting pipe 81, and a second spring 85 is provided on the assembly cover 84;

[0068] A water-blocking component 86 is mounted on the second spring 85, and the water-blocking component 86 is installed in conjunction with the limiting component 83.

[0069] The design of the connecting pipe 81 and the limiting member 83 ensures that the liquid can be effectively guided and controlled when it is discharged from the pump body 3. The design of the assembly cover 84 and the second spring 85 not only provides a sealing function, but also realizes an automatic opening and closing function through the elastic action of the spring, which improves the flexibility and adaptability of the system. The design of the water baffle 86 not only ensures the sealing of the outlet, but also can open quickly when needed to achieve efficient drainage. When the internal pressure of the pump body 3 increases, the water baffle 86 separates from the limiting member 83, and the liquid is discharged from the pump body 3 through the water outlet pipe 82, ensuring continuous pumping of the liquid.

[0070] As a preferred option, such as Figures 1 to 6 As shown, the drive mechanism 9 includes:

[0071] Piston tube 91 is mounted on mounting part 4, and piston block 92 is slidably mounted in the longitudinal direction inside piston tube 91;

[0073] The limiting mechanism 94 is located at the through hole of the piston tube 91. The limiting mechanism 94 is used to limit the rotation of the threaded rod 93, and the limiting mechanism 94 is slidably installed with the threaded rod 93 in the length direction.

[0074] The threaded tube 95 is rotatably mounted on the limiting mechanism 94, and the threaded rod 93 is connected to the threaded rod 94.

[0075] A power mechanism 96 is mounted on the base 1 and is used to provide rotational power to the threaded pipe 95.

[0076] The design of piston tube 91 and piston block 92 not only provides a stable power transmission path, but also ensures that piston block 92 can move smoothly within piston tube 91, providing continuous positive and negative pressure. The design of threaded rod 93 and limiting mechanism 94 prevents power loss caused by rotation of threaded rod 93. The design of threaded tube 95 realizes the conversion of rotary motion to linear motion, ensuring that piston block 92 can reciprocate as needed. The design of power mechanism 96 not only provides a stable and reliable power source, but also ensures the efficient operation of the entire system. When power mechanism 96 drives threaded tube 95 to rotate, it drives threaded rod 93 and piston block 92 to reciprocate within piston tube 91, thereby generating the required positive and negative pressure, realizing efficient pumping of liquid, and improving the power transmission efficiency and control accuracy of the system.

[0077] As a preferred option, such as Figures 1 to 6 As shown, the limiting mechanism 94 includes:

[0078] The fixing part 94a is located in the inner hole of the piston tube 91, and the threaded tube 95 is rotatably installed in conjunction with the shaft hole of the fixing part 94a.

This design greatly simplifies the installation work, making the installation and disassembly of the equipment more convenient and quick, and further enhancing the practicality and operability of the system.

[0083] Driven gear 96c is coaxially mounted on threaded tube 95, and driven gear 96c is meshed with driving gear 96b.

[0084] The design of the servo motor 96a not only provides a stable and reliable power source, but also ensures the efficient operation of the system through precise speed and position control. The design of the drive gear 96b and driven gear 96c realizes the precise transmission of power, ensuring that the threaded tube 95 can perform precise rotational motion as needed, thereby driving the threaded rod 93 and piston block 92 to reciprocate within the piston tube 91.

[0085] As a preferred option, such as Figures 1 to 6 As shown, an isolation member 97 is provided on the base 1, and both the driving gear 96b and the driven gear 96c are located in the isolation member 97;

[0086] The design of the isolator 97 provides a physical barrier to prevent dust, moisture and other impurities from entering the meshing area of ​​the drive gear 96b and the driven gear 96c, thereby avoiding wear or jamming caused by foreign objects.

[0087] As a preferred option, such as Figure 1 As shown, the base 1 is equipped with adjustable feet 11;
