[0030] The die-casting cooling circulating water system is composed of a die, a die cooling station, a distribution box, a water bucket, and water pipes connected. The die-casting cooling circulating water system has a very important impact on the die, the product, and safety. For die-casting machine products, the die temperature is one of the important parameters affecting the product quality, and the water flow rate of the die has an important impact on the die temperature. Usually, multiple pipelines are installed inside the die, connected to the die cooling station to form a loop. Solenoid valves are installed in each branch water circuit at the outlet of the distribution box, and the on-off of the solenoid valves in the water circuit is controlled by the die cooling station to keep the temperature of the return water circuit constant.

[0031] The problems brought by the above technology are: once a die leakage problem occurs during the normal production of the die-casting machine, it cannot be processed in time. The leaked cooling water may seep into the die, resulting in uncontrollable die temperature and causing product quality problems. Even if the cooling water sprays onto the aluminum alloy liquid, there is a potential safety hazard of explosion. Therefore, a rapid response control system for die-casting cooling circulating water leakage is particularly important.

[0032] In response to this, the present application proposes a die-casting cooling circulating water flow monitoring system. By comparing the flow difference between the first flowmeter 300 and the second flowmeter 400 through the monitoring console 500, it is possible to know whether there is a leakage in the cooling channels inside the die of the die-casting machine 100, so that the monitoring console 500 can notify the staff for timely processing to avoid causing a greater accident.

[0033] Refer toFigure 1 In the die-casting cooling circulating water flow monitoring system according to the embodiment of the present application, it includes a die-casting machine 100, a refrigeration device 200, a first flowmeter 300, a second flowmeter 400 and a monitoring console 500. Among them, the die-casting machine 100 is used to complete die-casting work, which is provided with a mold and a cooling channel is opened in the mold. The refrigeration device 200 conveys cooling water into the cooling channel to cool the mold. The first flowmeter 300 and the second flowmeter 400 are respectively connected to both ends of the cooling channel, and are used to detect the flow rate of the cooling water input into the cooling channel and discharged from the cooling channel. The monitoring console 500 can know whether there is a leakage in the cooling channel by comparing the flow rate difference between the first flowmeter 300 and the second flowmeter 400. If there is a leakage in the cooling channel, the flow rate in the second flowmeter 400 will be significantly less than the flow rate measured by the first flowmeter 300, so that the flow rate difference is too large, and the staff needs to be reminded to repair the mold.

[0034] Specifically, for the cooling channel in the die-casting machine mold, a water inlet pipe 110 and a water outlet pipe 120 are respectively connected to both ends thereof, and both the water inlet pipe 110 and the water outlet pipe 120 are connected to the refrigeration device 200. After the refrigeration device 200 cools and cools the cooling water, the cooling water enters the die-casting machine 100 from the water inlet pipe 110, and the cooling water after heat exchange re-enters the refrigeration device 200 from the water outlet pipe 120 for re-cooling. The first flowmeter 300 is installed on the water inlet pipe 110 and is used to detect the liquid flow rate in the water inlet pipe 110, and the second flowmeter 400 is installed on the water outlet pipe 120 and is used to detect the liquid flow rate in the water outlet pipe 120.

[0035] Both the first flowmeter 300 and the second flowmeter 400 are electrically connected to the monitoring console 500, and the monitoring console 500 detects whether there is a water leakage in the die-casting machine 100 by comparing the flow rate difference between the first flowmeter 300 and the second flowmeter 400.

[0036] Among them, both the first flowmeter 300 and the second flowmeter 400 adopt flowmeters with a resolution of 0.02 L / min to ensure that the detection accuracy meets the requirements.

[0037] Furthermore, the die-casting cooling circulating water flow monitoring system further includes a distribution box 600. There are multiple cooling channels in the die-casting machine 100 mold. The water inlet pipe 110 is connected to the distribution box 600. The distribution box 600 is connected to each cooling channel and conveys the cooling water to each cooling channel, which serves to split the water flow in the water inlet pipe 110 and guide it to each cooling channel respectively.

[0038] Further, the die-casting cooling circulating water flow monitoring system further includes a solenoid valve 700. There are multiple solenoid valves 700, which are arranged in one-to-one correspondence with the cooling channels. The solenoid valve 700 is arranged between the distribution box 600 and the cooling channels, and is used to control whether the cooling channels are communicated with the distribution box. When abnormal flow is found in some cooling channels, the corresponding solenoid valve 700 can be selected to close, so as to deactivate the corresponding cooling channels and reduce the impact on the production process.

[0039] Further, the die-casting cooling circulating water flow monitoring system further includes a water bucket 800. The water outlet pipe 120 is connected to the water bucket 800. The water bucket 800 is connected to each cooling channel and converges the cooling water to the water outlet pipe 120.

[0040] Further, the number of the first flow meters 300 and the second flow meters 400 is multiple and they are arranged in one-to-one correspondence with each cooling channel. By comparing the flow differences between the first flow meters 300 and the second flow meters 400 corresponding to the cooling channels, it can be known whether the cooling channel leaks, so that the staff can quickly understand which cooling channel has a problem and improve the subsequent maintenance efficiency.

[0041] Further, the die-casting cooling circulating water flow monitoring system further includes a temperature sensor 900. The temperature sensor 900 is installed on the water outlet pipe 120 and is used to detect the temperature of the cooling water in the water outlet pipe 120. Thus, the staff can adjust the refrigeration temperature of the refrigeration equipment 200 based on the detection data of the temperature sensor 900, so that the mold in the die-casting machine 100 is maintained within a certain working temperature range. Optionally, the temperature sensor 900 can be electrically connected to the refrigeration equipment 200, and the refrigeration equipment 200 can automatically adjust the refrigeration temperature based on the detection data of the temperature sensor 900, so as to achieve automatic closed-loop control of the refrigeration temperature.

[0042] Further, there are multiple cooling channels in the mold of the die-casting machine 100, and the number of the temperature sensors 900 is multiple and they are arranged in one-to-one correspondence with the cooling channels, and are used to detect the temperature of the cooling water after heat exchange in each cooling channel, so that the staff can more clearly understand the temperature change of the cooling water in each cooling channel.

[0043] Further, the die-casting cooling circulating water flow monitoring system further includes an analog module 1000. The first flow meters 300 and the second flow meters 400 are both electrically connected to the monitoring console 500 through the analog module 1000. The analog module 1000 is used to convert the analog signals of the first flow meters 300 and the second flow meters 400 into digital signals, so as to facilitate the monitoring console 500 to identify the data.

[0044] Further, the refrigeration equipment 200 is electrically connected to the monitoring console 500, and the monitoring console 500 controls the refrigeration equipment 200.

[0045] An alarm device is built into the monitoring console 500. When the difference between the first flowmeter 300 and the second flowmeter 400 exceeds the rated threshold, the alarm device issues a warning to remind the staff to perform maintenance. The alarm device can use a buzzer or other sound alarm to prompt the staff, or use a flashing light to prompt the staff in the form of an image, or combine auditory and visual prompts to warn the staff. The specific structure and prompting method will not be elaborated here.

[0046] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those of ordinary skill in the art without departing from the gist of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
