Description

Technical Field

[0001] The utility model relates to the technical field of mold cooling devices, in particular to a mold cooling device for valve casting. Background Art

[0002] Valves are control components in fluid conveying systems, with functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. According to the material, they are also divided into cast iron valves, cast steel valves, stainless steel valves, etc. In the valve casting process, molten iron is needed to cast the valve mold required for manufacturing. The mold often carries a lot of heat after use and needs to be cooled before the next casting can be completed, which poses a great obstacle to the project.

[0003] For example, a mold cooling device with publication number CN102019652A includes a cooling hood and a template. The template is embedded in the cooling hood. A flow channel is formed between the cooling hood and the template. The cooling hood is formed with a water inlet and a water outlet, each of which is connected to the flow channel. The template is provided with a perforation extending through the template, one end of which corresponds to the water outlet.

[0004] The above-mentioned device mainly adopts a cooling cover set on the outside of the template to dissipate heat to the inside and outside of the template at the same time, thereby effectively improving the heat dissipation efficiency. However, water cooling and other cooling methods have many disadvantages. They require good pipeline sealing and unobstructed water pipes, which wastes a lot of water resources. This method has a large heat capacity and can achieve rapid cooling, but when the cooling temperature exceeds 100°C, steam explosions are prone to occur. The temperature generated by the mold after pouring is generally quite high, which makes the above-mentioned accidents prone to occur. Utility Model Content

[0005] The purpose of the utility model is to provide a valve casting mold cooling device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold cooling device for valve casting, comprising a cooling cover, a transmission mechanism installed on the surface of the cooling cover, and a driving power supply installed on the upper end of the transmission mechanism, and a transmission pipeline installed at the lower end of the transmission mechanism, a water tank installed at the lower end of the transmission pipeline, and a water inlet installed on the surface of the water tank, and a telescopic column installed between the cooling covers, a bearing plate installed in the middle of the telescopic column, and a limit block installed on the upper end of the bearing plate, and a straightening ring installed around the limit block.

[0007] Preferably, the inner surface of the cooling cover is provided with a plurality of recesses, and a ventilation cover is installed outside the recesses, and a rotary motor is installed inside the recesses.

[0008] Preferably, a fixed rod is mounted on the surface of the rotary motor inside the cooling cover, and a rotating shaft is mounted on the front end of the rotary motor, while a rotating end head is mounted on the front end of the transmission shaft.

[0009] Preferably, a plurality of rotating fan blades are installed on the surface of the rotating end head, and a humidifier is installed between the ventilation covers, and a plurality of humidification ports are provided on the inclined surface of the humidifier.

[0010] Preferably, a connecting line is provided at the rear end of the rotary motor, and the connecting line is connected to the transmission pipeline, and the transmission pipeline is connected to the upper end transmission mechanism.

[0011] Preferably, a connecting line is assembled inside the telescopic column to the cooling cover on the other side.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Compared with other valve casting mold cooling devices, this device mainly uses air cooling. Air cooling does not require a completely enclosed space and has a relatively simple structure. It does not need to consider too many environmental factors when effectively cooling the object. In addition, the cost of the air cooling system itself is not high, which is better in terms of saving.

[0014] 2. In addition, considering that the independent wind system is not very effective in cooling the mold, a large humidifier is installed in the middle of the air cooling device. Since the air cooling efficiency is relatively slow, the high temperature generated by the mold may cause the air cooling fan to overheat. The installation of the humidifier is used to deliver mist to the air cooling port, which can reduce the temperature of the air cooling fan and accelerate the cooling effect on the mold.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3 , the utility model provides a technical solution:

[0021] Figure 1 This is an overview of the front of the device. The main body is a cooling cover 1. A transmission mechanism 2 is installed on the surface of the cooling cover 1, and a driving power supply 3 is installed on the upper end of the transmission mechanism 2. A transmission line is provided at the bottom of the driving power supply 3 to connect the transmission mechanism 2. Several wires are provided inside the transmission mechanism 2, which are respectively connected to the corresponding internal branches of the transmission pipeline. At the same time, a transmission pipeline 5 is installed at the lower end of the transmission mechanism 2, and a water tank 6 is installed at the lower end of the transmission pipeline 5. The surface of the water tank 6 is equipped with a water inlet 4. The water tank 6 is connected to the water inlet of the internal humidifier 11. The water stored in the water tank 6 is used to cover the cooling fan with water mist, and the fan is used to cool the cooling fan. The wind force blows the water mist emitted from the corresponding port to the mold surface, accelerating the cooling effect of the mold. At the same time, a telescopic column 9 is assembled between the cooling covers 1, a bearing plate 7 is installed in the middle of the telescopic column 9, and a limit block 10 is installed on the upper end of the bearing plate 7. At the same time, a straightening ring 8 is assembled around the limit block 10. Since most valve molds have a cylindrical design, the design of the limit block 10 plus the straightening ring 8 can support and limit most molds to ensure stability during cooling. The telescopic column 9 at the lower end can be used to adjust the distance between the two cooling covers 1 to adjust the effective spacing between them according to the size of the mold;

[0022] Figure 2This is a top view of the device. The main body is a cooling cover 1. The inner surface of the cooling cover 1 is provided with a plurality of recesses, and a ventilation cover 13 is installed on the outside of the recess. At the same time, a rotary motor 12 is installed inside the recess. A fixed rod is installed on the surface of the rotary motor 12 inside the cooling cover 1, and a rotating shaft is installed at the front end of the rotary motor 12. At the same time, a rotating end 15 is installed at the front end of the transmission shaft. A plurality of rotating blades 14 are installed on the surface of the rotating end 15. The power transmitted by the rear rotary motor 12 is transmitted to the front rotary end 15 through the transmission shaft. The design of the rotating end 15 provides an empty mounting carrier for the rotating fan blades 14. The rotation of the rotating end 15 drives the rotation of the rotating fan blades 14 to provide air cooling effect for the corresponding part of the cooling cover 1. The humidifier 11 is installed between the ventilation cover 13. At the same time, a plurality of humidification ports are provided on the inclined surface of the humidifier 11. The humidification ports correspond to the front end of the ventilation cover 13, so that the ventilation cover 13 can blow the emitted water mist to the mold surface to accelerate the cooling of the mold. At the same time, it can also have a cooling effect on the entire air-cooling fan to avoid overheating.

[0023] Figure 3 This is an internal overview of the device. The main body is a rotary motor 12. A connecting line is provided at the rear end of the rotary motor 12, and the connecting line is connected to the transmission pipeline 5. At the same time, the transmission pipeline 5 is connected to the upper end transmission mechanism 2. The connecting line is assembled inside the telescopic column 9 to the cooling cover 1 on the other side.

[0024] During actual use, the mold is clamped by a robotic arm and placed on the middle limit block 10 of the cooling cover 1, and supported by the straightening ring 8 installed on the side. The material used is high-temperature resistant material, and the structure is strong and not easy to damage. As the mold is placed, the distance between the telescopic columns 9 is adjusted, and the driving power supply 3 is turned on. As the transmission mechanism 2 transmits electric energy, the transmission pipeline distributes each electric energy line to the rotating motor 12 inside each air-cooling fan. The rotation of the rotating motor 12 drives the front rotating end 15, and the rotating fan blades 14 rotate to cool. The humidifier 11 installed on the side delivers cooling water mist to the air-cooling fan port, which is driven by the wind flow to the mold surface, thereby accelerating the cooling effect of the mold. At the same time, the missed water mist can also cool the air-cooling fan itself to prevent overheating.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
