[0046] The die-casting machine is a machine that hydraulically injects molten metal into the die-casting mold under pressure to cool and form, and obtains fixed metal die-castings after the mold is opened. In the die-casting process, since the melting point of metals is generally high, die-castings are often water-cooled after casting to dissipate heat from the die-casting mold; and some die-casting molds are equipped with multiple cooling water channels to form a cooling distribution, and workers cannot intuitively judge the conditions of each cooling water channel inside. When a cooling water channel is blocked inside the die-casting mold due to impurities or scaling in the cooling water, or when a cooling water channel has poor cooling effect in the die-casting mold, the problem cannot be discovered in time, which will affect the quality of the product and lead to an increase in the defective rate.

[0047] Based on this, in order to solve the above problems, the present application designs a monitoring device, which connects the monitoring device to the die-casting mold and enables each water inlet pipe of the monitoring device to receive each cooling water in the die-casting mold respectively, so that each water inlet pipe can detect the parameters of a certain cooling water in the die-casting mold in real time through the monitoring component, such as the flow rate, temperature and pressure of the cooling water; it is convenient to judge the actual status of each cooling water in the die-casting mold in real time, which can prevent and discover internal problems of the die-casting mold, improve the quality of die-casting products, and reduce the defective rate.

[0048] See also Figure 1 and Figure 2The embodiment of the present application provides a monitoring device for monitoring the parameters of cooling water in a mold, the monitoring device comprising a frame 1 and a water inlet monitoring module 2, a return water pipe 3 and a water outlet pipe 4 having a water outlet 401 arranged on the frame 1; the water inlet monitoring module 2 comprises a plurality of water inlet pipes 5 arranged side by side along a first direction X and having a water inlet 501, and a monitoring component 6 arranged on each water inlet pipe 5, the monitoring component 6 being used to detect the parameters of the cooling water in the water inlet pipe 5; one end of the return water pipe 3 is connected to the water outlet pipe 4, and the other end of the return water pipe 3 is connected to each water inlet pipe 5 of the water inlet monitoring module 2.

[0049] The monitoring device of the present application is specifically used to connect with the die-casting mold and receive multiple cooling water channels in the die-casting mold; during the die-casting process, since the melting point of metals is generally high, the die-casting parts are often water-cooled after casting to dissipate the heat of the die-casting mold, and multiple cooling water channels are provided in the die-casting mold to form a sufficient cooling distribution; each cooling water channel in the die-casting mold is respectively connected to the water inlet 501 of each water inlet pipe 5 of the water inlet monitoring module 2, so that each cooling water channel in the die-casting mold flows through the die-casting mold and cools the die-casting mold before flowing into each water inlet pipe 5.

[0050] Specifically, the water inlet monitoring module 2 includes a plurality of water inlet pipes 5, and the plurality of water inlet pipes 5 are arranged side by side along the first direction X, so that the device structure is neat and the spatial layout is reasonable. The number of water inlet monitoring modules 2 is not limited and is set according to the number of cooling water channels in the actual die-casting mold; the number of water inlet monitoring modules 2 can be one group or multiple groups.

[0051] The first direction X is the X direction shown in the figure. Optionally, the first direction X is perpendicular to the extension direction of the water inlet pipe 5 ; or, the first direction X is perpendicular to the length direction of the frame 1 , so that multiple water inlet pipes 5 can be arranged side by side.

[0052] It can be understood that a monitoring component 6 is provided on each water inlet pipe 5, and the monitoring component 6 is used to detect the parameters of the cooling water in the water inlet pipe 5; the parameters of the cooling water may include but are not limited to: the flow rate of the cooling water, the temperature of the cooling water, the pressure of the cooling water, the degree of dirtiness of the cooling water, etc., and the monitoring component 6 may include a flow meter, a thermometer, a pressure gauge, and a sewage detection instrument, etc. By detecting the parameters of the cooling water in each water inlet pipe 5, the cooling water in each channel of the die-casting mold can be monitored in real time, so as to understand the actual status of each channel of the cooling water in the die-casting mold, and prevent or promptly discover the bad problems of the cooling water channel in the die-casting mold.

[0053] For example, the monitoring component 6 can detect the flow rate of cooling water in the water inlet pipe 5; when it is detected that the flow rate of cooling water in the water inlet pipe 5 is small, the cooling water circuit in the die-casting mold may be blocked. Alternatively, the monitoring component 6 can detect the temperature of cooling water in the water inlet pipe 5. When it is detected that the temperature of cooling water in the water inlet pipe 5 is too high, it indicates that the cooling effect of the cooling water circuit in the die-casting mold is not good, and it is necessary to replace the cooling water or further detect the internal working condition of the die-casting mold.

[0054] The return water pipe 3 is simultaneously connected to multiple water inlet pipes 5 of the water inlet monitoring module 2, that is, the cooling water in the multiple water inlet pipes 5 can converge into the return water pipe 3, and flow to the outlet water pipe 5 through the return water pipe 3, and the cooling water in each water inlet pipe 5 is discharged by the outlet water pipe 4, making it convenient for the device to drain water.

[0055] Specifically, the number of return pipes 3 can be the same as the number of inlet monitoring modules 2, that is, one group of inlet monitoring modules 2 is equipped with one return pipe 3; or the number of return pipes 3 can be greater than the number of inlet monitoring modules 2, that is, one group of inlet monitoring modules 2 can also be equipped with multiple return pipes 3, which is not limited here. The number of outlet pipes 5 can also be one or more, which is selected according to the specific design and is not limited here.

[0056] The monitoring device of the present application is connected to the die-casting mold and each water inlet pipe 5 of the monitoring device receives each cooling water in the die-casting mold respectively, so that each water inlet pipe 5 can detect the parameters of a cooling water in a certain way in the die-casting mold in real time through the monitoring component 6, such as the flow rate, temperature and pressure of the cooling water; it is convenient to judge the actual status of each cooling water in the die-casting mold in real time, and can prevent and discover whether there is blockage or poor cooling effect inside the die-casting mold, thereby improving the quality of die-casting products and reducing the defective rate.

[0057] refer to Figure 2 , Figure 3 , Figure 4 In some embodiments, the number of water inlet monitoring modules 2 is at least 2 groups; at least 2 groups of water inlet monitoring modules 2 are arranged side by side on the frame 1 along a first direction X, and the first direction X is perpendicular to the extension direction of the water inlet pipe 5; and / or, at least 2 groups of water inlet monitoring modules 2 are arranged on the frame 1 at intervals along a second direction Y, and the second direction Y is the extension direction of the water inlet pipe 5.

[0058] It can be understood that for some larger die-casting molds, the number of cooling water channels inside the die-casting mold is relatively large; then, by setting two or more water inlet monitoring modules 2 on the frame 1, the monitoring device can have multiple water inlet pipes 5, which is suitable for die-casting molds with a large number of cooling water channels.

[0059] In some embodiments, reference Figure 3 At least two groups of water inlet monitoring modules 2 are arranged side by side on the frame 1 along a first direction X, and the first direction X is perpendicular to the extension direction of the water inlet pipe 5.

[0060] Along the first direction X, at least two groups of water inlet monitoring modules 2 are arranged side by side on the frame 1, with a compact structure, that is, a plurality of water inlet pipes 5 are arranged along the first direction X, the number of the water inlet pipes 5 is increased, and multiple cooling water channels in the die-casting mold can be connected at the same time; and the water inlets 501 of each water inlet pipe 5 are oriented in a unified direction, which is convenient for connecting cooling water.

[0061] In other embodiments, reference Figure 3 At least two groups of water inlet monitoring modules 2 are arranged side by side on the frame 1 along the second direction Y, and the second direction Y is the extension direction of the water inlet pipe.

[0062] Specifically, the second direction Y is the Y direction shown in the figure. Along the second direction Y, at least two groups of water inlet monitoring modules 2 are arranged at intervals on the frame 1; by arranging the two groups of water inlet monitoring modules 2 at intervals along the second direction Y, the water inlet 501 of the water inlet pipe 5 is connected to the external water pipe without affecting the connection; and the monitoring device is made compact in structure, forming multiple water inlet pipes 5 with a reasonable layout.

[0063] By adopting the above technical solution, multiple groups of water inlet monitoring modules 2 can be arranged in an array on the frame 1 along the first direction X and / or the second direction Y. The structural layout is compact, the number of water inlet pipes 5 of the device is increased, and the device can simultaneously detect multiple cooling water channels in the die-casting mold.

[0064] refer to Figure 2 , Figure 4 , Figure 5 In some embodiments, the number of return water pipes 3 is configured to be the same as the number of water inlet monitoring modules 2 .

[0065] It can be understood that each group of water inlet monitoring modules 2 is equipped with a return pipe 3, one end of the return pipe 3 is connected to each water inlet pipe 5 of each group of water inlet monitoring modules 2, and the other end of the return pipe 3 is connected to the outlet pipe 4, so that the drainage is stable.

[0066] In some embodiments, the number of the outlet pipe 4 is 1. Then, the multiple return pipes 3 guide the cooling water to the one outlet pipe 4 for discharge together, so that the drainage efficiency is high and the cost is saved.

[0067] refer to Figure 2-Figure 4 In some embodiments, the water inlet monitoring module 2 also includes connecting plates 201 located on both sides; the water inlet monitoring module 2 is connected to the frame 1 through the connecting plates 201; and / or, the water inlet monitoring module 2 is connected to the connecting plates 201 of adjacent water inlet monitoring modules 2 through the connecting plates 201.

[0068] Specifically, each group of water inlet monitoring modules 2 is provided with connecting plates 201 on both sides for connection support, and multiple water inlet pipes 5 are arranged side by side between the two connecting plates 201; when the water inlet monitoring module 2 is connected to the frame 1, the connecting plate 201 on the side of the water inlet monitoring module 2 is connected and fixed to the frame 1, which is convenient for connection and provides stable support.

[0069] When a plurality of water inlet monitoring modules 2 are arranged along the first direction X, the connecting plates 201 of two adjacent water inlet monitoring modules 2 are connected and fixed, so that each group of water inlet monitoring modules 2 has good structural stability and ensures the reliability of the device.

[0070] refer to Figure 2 , Figure 3 In some embodiments, the monitoring component 6 includes a flow meter 7 , and / or the monitoring component 6 includes a thermometer 8 .

[0071] It can be understood that the monitoring component 6 can also include a flow meter 7 for measuring the cooling water flow in the water inlet pipe 5 and a thermometer 8 for measuring the temperature of the cooling water flow in the water inlet pipe 5; that is, it can simultaneously monitor the flow and temperature of the cooling water.

[0072] Alternatively, when only the flow rate or the temperature of the cooling water in the water inlet pipe 5 needs to be monitored, the monitoring component 6 may also only include one of the flow meter 7 for measuring the flow rate of cooling water in the water inlet pipe 5 or the thermometer 8 for measuring the temperature of the flow rate of cooling water in the water inlet pipe 5, which can be freely selected according to design requirements without specific limitation.

[0073] In some embodiments, the water inlet pipe 5 is a transparent pipe, and the flow meter 7 is a visual float flow meter arranged in the water inlet pipe 5.

[0074] Specifically, the water inlet pipe 5 is designed as a transparent pipe, and a scale is formed on the water inlet pipe 5. The flow meter 7 is a visual float flow meter arranged in the water inlet pipe 5. Then, when the cooling water flows through the water inlet pipe 5, the position of the flow meter 7 can be read intuitively to know the flow rate of the cooling water in the water inlet pipe 5. The structure is simple and reliable, and costs are effectively saved.

[0075] refer to Figure 2 , Figure 3 In some embodiments, the monitoring component 6 also includes a regulating valve 9 which is arranged on the water inlet pipe 5 and is used to control the conduction and closure of the water inlet pipe 5 .

[0076] It can be understood that a regulating valve 9 is provided on the water inlet pipe 5, and the regulating valve 9 can adjust the cooling water in the water inlet pipe 5, so that the cooling water is conducted or cut off inside the water inlet pipe 5; then, only some cooling water inside the water inlet pipe 5 can be selectively conducted, so as to specifically detect the conditions of one or several cooling water lines in the die-casting mold.

[0077] Specifically, the regulating valve 9 and the thermometer 8 are arranged on the water inlet pipe 5 at intervals along the first direction to avoid mutual interference when the two are installed.

[0078] Please refer to Figure 2-Figure 5 In some embodiments, the frame 1 includes two brackets 101 spaced apart along a first direction X and a beam 102 connected between the two brackets 101; a plurality of water inlet pipes 5 are arranged between the two brackets 101; a water outlet pipe 4 is arranged on the beam 102; and a return water pipe 3 extends along the bracket 101 and the beam 102.

[0079] Specifically, a plurality of water inlet pipes 5 are installed between two brackets 101 , and a water outlet pipe 4 is arranged on a crossbeam 102 and the crossbeam 102 is connected between the two brackets 101 , so that the structure support of the monitoring device is stable.

[0080] The crossbeam 102 is arranged below the water inlet pipe 5, and the return pipe 3 flows the cooling water in the water inlet pipe 5 downward into the water inlet pipe 5. The return pipe 3 extends along the bracket 101 and the crossbeam 102, and the layout is reasonable, which can reduce the space occupied.

[0081] refer to Figure 4 and Figure 5 In some embodiments, the return water pipe 3 includes a first return water pipe 301 connected to multiple water inlet pipes 5, a second return water pipe 302 arranged on the crossbeam 102 and connected to the water outlet pipe 4, and a third return water pipe 303 arranged on the bracket 101 and connected between the first return water pipe 301 and the second return water pipe 302.

[0082] It can be understood that the first return water pipe 301 is arranged along the first direction X and is connected to the end of each water inlet pipe 5 away from the water inlet 501, so that the cooling water in the multiple water inlet pipes 5 can eventually converge into the return water pipe 3; the second return water pipe 302 is arranged on the crossbeam 102 along the first direction X and is connected to the water outlet pipe 4; the third return water pipe 303 is arranged on the bracket 101 along the second direction Y and is respectively connected to the first return water pipe 301 and the second return water pipe 302; then the cooling water in the water inlet pipe 5 will flow through the first return water pipe 301, the third return water pipe 303 and the second return water pipe 302 in sequence and finally flow to the water outlet pipe 4.

[0083] By adopting the above technical solution, the return pipe 3 is arranged along the bracket 101 and the crossbeam 102, forming a good diversion effect, a reasonable layout and a stable structure.

[0084] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
