Description

Technical Field

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

[0002] As the mold industry becomes more and more widespread, mold processing refers to the processing of molding and blanking tools, in addition to shearing molds and casting molds. Usually, the mold consists of two parts: the upper mold and the lower mold. One is to place the steel plate between the upper and lower molds, and realize the molding of the material under the action of the press. When the press is opened, the workpiece determined by the mold shape will be obtained or the corresponding waste will be removed. The other is a casting mold, which uses a specific mold to cast the workpiece product. During the use of the mold, the mold needs to be cooled to avoid damage to the internal punch and device due to excessive temperature. The most commonly used method is to open a water channel on the mold core to take away the temperature through the water channel to achieve cooling. This cooling method requires the use of a water cooling device.

[0003] Patent No. CN202221328810.6 discloses a mold water cooling device, comprising: a cooling plate and a primary cooling layer arranged on the cooling plate and a secondary cooling layer arranged above the primary cooling layer, the primary cooling layer comprises a primary fixed plate and an air cooler, the air cooler is arranged at the center of the fixed plate, the air cooler comprises a power base and fan blades distributed around the power base, the power base is a shell inner cavity structure, a motor is arranged in the shell, the motor provides kinetic energy for the fan blades, a refrigeration mechanism is arranged around the motor, and a plurality of refrigeration ports are arranged on the outer surface of the shell; the primary cooling layer is connected to the secondary fixed plate through a connecting piece, a plurality of condensing tubes are arranged on the secondary fixed plate, the condensing tubes are curved and distributed all over the outer surface of the secondary fixed plate, a water inlet is arranged at one end of the condensing tube, and a water outlet is arranged at the other end of the condensing tube, the primary cooling layer is provided with an air cooler to bring cold air to the condensing tube in the secondary cooling layer, thereby reducing the temperature of water in the condensing tube, so as to better cool the mold;

[0004] This technical solution uses an air cooler to blow the cold air generated by the condenser toward the water in the water tank, thereby quickly cooling the water. However, when blowing, only the surface of the water can come into contact with the cold air, resulting in a slow cooling effect and increased energy consumption. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a mold water cooling device.

[0006] The utility model is achieved in this way:

[0007] A mold water cooling device includes a water cooling mechanism, an air supply mechanism and an anti-backflow mechanism, the water cooling mechanism includes a water cooling box, one side of the water cooling box is provided with an opening, a plurality of brackets are installed on the inner bottom of the water cooling box, the air supply mechanism includes a condenser, and the condenser is installed inside the water cooling box and supported by the bracket, the input end of the condenser extends to the outside of the water cooling box through the opening, an air cooler is installed outside the water cooling box, and the input end of the air cooler is connected to the input end of the condenser, a plurality of air holes are opened on the top of the part of the condenser located in the water cooling box, and the anti-backflow mechanism is installed on the top of the air holes.

[0008] The beneficial effect of adopting the above further scheme is that the water cooling box is filled with an appropriate amount of cooling water for cooling the mold. After the air cooler sends the cold air into the condenser, it will be discharged through the pores. Because the cold air is insoluble in water and its density is lower than that of cooling water, the cold air will float out from the cooling water. In this process, the cold air will come into contact with a large amount of cooling water, thereby improving the cooling effect of the cooling water.

[0009] Furthermore, the condenser includes a plurality of concentric annular pipes, and a conduit is connected between the plurality of annular pipes, and the outer side of the outermost annular pipe is also connected to an air inlet pipe, and the input end of the condenser is located at the free end of the air inlet pipe.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the number of pipes of the condenser in the water cooling box is increased, thereby increasing the amount of discharged cold air and improving the cooling effect of the cold air on the coolant. At the same time, the air inlet pipe and the opening are sealed to prevent cooling water from flowing out of the gap between them.

[0011] Furthermore, a motor is installed on the outside of the water cooling box, a stirring shaft is installed inside the water cooling box through a bearing, the output end of the motor is transmission-connected to the stirring shaft, and a plurality of stirring blades are installed on the outside of the stirring shaft.

[0012] The beneficial effect of adopting the above further scheme is that the motor is used to drive the stirring shaft to rotate, so that the stirring blades stir the coolant, further increasing the contact area between the coolant and the cold air. At the same time, the connection between the motor output end and the stirring shaft is sealed to prevent cooling water from flowing out of the water cooling box.

[0013] Furthermore, a pump is installed on the top of the water cooling box, and a pair of grooves are opened on the top of the water cooling box, in which a first water outlet pipe and a water inlet pipe are respectively installed, the input end of the pump is connected to the first water outlet pipe, and the output end of the pump is connected to the second water outlet pipe, and the bottom end of the first water outlet pipe is close to the top of the condenser.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the second water outlet pipe and the water inlet pipe are respectively connected to the two ends of the water channel on the mold core. After the pump is started, the cooling water can be pumped into the water channel through the first water outlet pipe and the second water outlet pipe. Because the pressure at one end of the water channel is greater than that at the other end, the cooling water will flow in the water channel, that is, flow into the water channel from the second water outlet pipe, and flow into the water cooling box from the water inlet pipe, thereby completing the circulation of cooling water and absorbing the temperature of the mold to achieve the purpose of cooling the mold.

[0015] Furthermore, pipe joints are installed at the top ends of the second water outlet pipe and the water inlet pipe.

[0016] The beneficial effect of adopting the above further scheme is that the type of pipe joint matches the type of interface at both ends of the waterway. Specifically, if the interfaces at both ends of the waterway are threaded connections, the pipe joint is a sleeve joint with threads on the outside. If the interfaces at both ends of the waterway are flange-equipped bolt connections, the pipe joint is a pipe joint with flanges. At the same time, a sealing treatment is performed between the pipe joint and the waterway, such as a sealing ring or raw tape.

[0017] Furthermore, a water supply groove is provided on one side of the water cooling box near the top, a water supply pipe is connected to the outside of the water supply groove, and one end of the water supply pipe is connected to a valve body.

[0018] The beneficial effect of adopting the above further solution is that after a period of time, the cooling water may be reduced due to evaporation, etc., and the user can then open the valve body and add cooling water to the water cooling box through the water supply pipe.

[0019] Furthermore, the anti-backflow mechanism includes an air outlet pipe, and the air outlet pipe is installed at the top of the air hole, a connecting sleeve is provided on the top of the air outlet pipe, a cavity penetrating the bottom is opened at the top of the connecting sleeve, a connecting cover is installed at the bottom of the cavity, and the connecting cover is an inverted frustum, the air outlet pipe and the bottom of the connecting cover are connected, a blocking ball is sliding inside the connecting cover, and the blocking ball blocks the bottom of the connecting cover, a connecting disk is installed on the top of the cavity, a spring is connected between the connecting disk and the blocking ball, and a through hole is opened at the center of the connecting disk.

[0020] Furthermore, a hole is opened on one side of the water cooling box near the top, and a PTFE membrane is installed in the through hole and the hole.

[0021] The beneficial effect of adopting the above further scheme is that, by utilizing the anti-backflow mechanism, the water pressure from above will cause the blocking ball to block the bottom of the connecting cover, thereby preventing cooling water from entering the condenser through the air hole. Only when the pressure of the cold air is greater than the water pressure, the blocking ball will be lifted up to allow the cold air to be discharged through the air hole. Therefore, during the process, the pressure of the cold air is greater than the water pressure. Therefore, during the process of cold air discharge, condensed water cannot enter the condenser. In actual use, if the air pressure of the discharged cold air on the blocking ball cannot be greater than the water pressure of the condensed water on the blocking ball due to a large amount of condensed water, a boosting device such as a booster pump can be installed on the outside of the water cooling box and correctly connected to the condenser so that the air pressure is greater than the water pressure. When the cold air stops being discharged, the pressure on the blocking ball will gradually decrease until it is less than the water pressure. At this time, the water pressure will press the blocking ball downward. In the process, some condensed water will enter the condenser. Through the use of PTFE membrane, the inflow of condensed water can be hindered without hindering the outflow of cold air, thereby avoiding the above situation.

[0022] The beneficial effect of the utility model is as follows: the utility model obtains a mold water cooling device through the above design, and a proper amount of cooling water is filled in the water cooling box for cooling the mold. After the air cooler sends the cold air into the condenser tube, it will be discharged through the pores. Because the cold air is insoluble in water and has a lower density than cooling water, the cold air will float out from the cooling water. In this process, the cold air will contact with a large amount of cooling water, thereby improving the cooling effect of the cooling water. BRIEF DESCRIPTION OF THE DRAWINGS

The condenser 2002 is located at the top of the water cooling box 1001 and has a plurality of air holes. The backflow prevention mechanism 300 is installed on the top of the air holes. The water cooling box 1001 is filled with a proper amount of cooling water for cooling the mold. After the air cooler 2001 sends the cold air into the condenser 2002, it will be discharged through the air holes. Since the cold air is insoluble in water and has a lower density than cooling water, the cold air will float out of the cooling water. In this process, the cold air will come into contact with a large amount of cooling water, thereby improving the cooling effect of the cooling water.

[0033] Embodiment 2 of a mold water cooling device of the utility model

[0034] Reference Figure 1-Figure 4 Specifically, a pump 1003 is installed on the top of the water cooling box 1001. A pair of slots are opened on the top of the water cooling box 1001. A first water outlet pipe 1009 and a water inlet pipe 1006 are installed in the pair of slots respectively. The input end of the pump 1003 is connected to the first water outlet pipe 1009, and the output end of the pump 1003 is connected to the second water outlet pipe 1004. The bottom end of the first water outlet pipe 1009 is close to the top of the condenser 2002. The second water outlet pipe 1004 and the water inlet pipe 1006 are respectively connected to the two ends of the water channel on the mold core. After the pump 1003 is started, the cooling water can be pumped into the water channel through the first water outlet pipe 1009 and the second water outlet pipe 1004. Because the pressure at one end of the water channel is greater than that at the other end, the cooling water will be in the water channel. Flow, that is, flow into the water circuit from the second water outlet pipe 1004, and flow into the water cooling box 1001 from the water inlet pipe 1006, thereby completing the circulation of cooling water and absorbing the temperature of the mold to achieve the purpose of cooling the mold. The top of the second water outlet pipe 1004 and the water inlet pipe 1006 are both installed with pipe joints 1005. The type of pipe joints 1005 matches the type of interfaces at both ends of the water circuit. Specifically, if the interfaces at both ends of the water circuit are threaded connections, the pipe joints 1005 are sleeve joints with threads on the outside. If the interfaces at both ends of the water circuit are flange-equipped bolt connections, the pipe joints 1005 are flange-equipped pipe joints. At the same time, the connection between the pipe joints 1005 and the water circuit is sealed, such as with sealing rings or raw tape.

[0035] Embodiment 3 of a mold water cooling device of the utility model

[0036] Reference Figure 1-Figure 4 Specifically, the anti-backflow mechanism 300 includes an air outlet pipe 3001, and the air outlet pipe 3001 is installed at the top of the air hole, a connecting sleeve 3002 is provided at the top of the air outlet pipe 3001, a cavity penetrating the bottom is opened at the top of the connecting sleeve 3002, a connecting cover 3003 is installed at the bottom of the cavity, and the connecting cover 3003 is in the shape of an inverted truncated cone, the air outlet pipe 3001 and the bottom of the connecting cover 3003 are connected, a card ball 3006 is slidably provided inside the connecting cover 3003, and the card ball 3006 006 blocks the bottom of the connection cover 3003, a connection plate 3004 is installed on the top of the cavity, a spring 3005 is connected between the connection plate 3004 and the card ball 3006, a through hole 3007 is opened at the center of the connection plate 3004, a hole is opened near the top on one side of the water cooling box 1001, and a PTFE membrane is installed in the through hole 3007 and the hole. By using the anti-backflow mechanism 300, the water pressure above will cause the card ball 3006 to block the bottom of the connection cover 3003, As a result, cooling water cannot enter the condenser 2002 through the air holes. Only when the pressure of the cold air is greater than the water pressure will the ball 3006 be lifted up to allow the cold air to be discharged through the air holes. Therefore, the pressure of the cold air is greater than the water pressure during the process. Therefore, during the discharge of the cold air, the condensed water cannot enter the condenser 2002. In actual use, if the amount of condensed water is large, resulting in the air pressure of the discharged cold air on the ball 3006 not being greater than the water pressure of the condensed water on the ball 3006, a boosting device such as a booster pump can be installed on the outside of the water cooling box 1001 and properly connected to the condenser 2002 to make the air pressure greater than the water pressure; when the cold air stops being discharged, its pressure on the ball 3006 will gradually decrease until it is less than the water pressure. At this time, the water pressure will press the ball 3006 downward. In this process, some condensed water will enter the condenser 2002. By using the PTFE membrane, the inflow of condensed water can be hindered without hindering the outflow of cold air, thereby avoiding the above situation.

[0037] Specifically, the working principle of the mold water cooling device is as follows: when in use, the second water outlet pipe 1004 and the water inlet pipe 1006 are respectively connected to the two ends of the water channel on the mold core. After the pump 1003 is started, the cooling water can be pumped into the water channel through the first water outlet pipe 1009 and the second water outlet pipe 1004. Because the pressure at one end of the water channel is greater than that at the other end, the cooling water will flow in the water channel, that is, flow into the water channel from the second water outlet pipe 1004, and flow into the water cooling box 1001 from the water inlet pipe 1006, thereby completing the circulation of the cooling water and absorbing the temperature of the mold. , in order to achieve the purpose of cooling the mold. During this process, the air cooler 2001 and the motor 1002 are kept working. After the air cooler 2001 sends the cold air into the condenser 2002, it will be discharged through the pores. Because the cold air is insoluble in water and its density is lower than that of cooling water, the cooling water will float out. During this process, the cold air will come into contact with a large amount of cooling water. The motor 1002 is used to drive the stirring shaft 1010 to rotate, so that the stirring blades 1011 stir the coolant, further increasing the contact area between the coolant and the cold air, thereby improving the cooling effect of the cooling water.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
