In this way, mold problems can be corrected and adjusted in time to ensure smooth operation and product quality.

[0018] 1. Water storage tank; 2. Water pipe connected to mold; 3. Return pipe; 4. Pneumatic pressure boosting valve; 5. Gas pressure boosting pipe; 6. One-way check valve; 7. Air outlet; 8. Pressure gauge. DETAILED DESCRIPTION

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0020] like Figure 1 As shown, a pneumatic booster water testing machine includes a water tank 1. The water tank 1 is a stainless steel container. The stainless steel material can reduce the rusting phenomenon that occurs when the water tank 1 comes into contact with water. A trolley is fixedly connected to the lower side of the water tank 1 to facilitate the mobile water testing machine equipment for on-site operations.

[0021] The interior of the water tank 1 is filled with water or other fluid media. The water testing machine mainly introduces water flow into the water tank 1 through a booster pump and a pipeline. A gas pressurizing mechanism is installed on the water tank 1. At this time, the water inside the water tank 1 can be pressurized by the gas pressurizing mechanism, preferably pressurized to 10-11KG. The lower part of the water tank 1 is connected to a mold water pipe 2, and the mold water pipe 2 can be connected to the water channel of the mold. The pressurized water can enter the mold through the mold water pipe 2 for water testing. The water pressure in the mold will change with the air pressure in the water tank 1. After pressurization, the sealing of the mold water channel can be tested.

[0022] A return pipe 3 is connected to the mold water pipe 2. One end of the return pipe 3 away from the mold water pipe 2 is connected to the upper part of the water storage tank 1. A pressure gauge 8 is installed on the return pipe 3. The current pressure in the mold water channel can be monitored by the pressure gauge 8. If the pressure drops, it means that the sealing of the mold water channel is abnormal. At this time, the mold leakage position is checked to accurately determine the leakage position, which can improve the processing efficiency. It has high detection efficiency, fast speed, good reliability and high detection accuracy. It can effectively shorten the time of mold water testing and improve the accuracy of water testing, making the mold manufacturing process more refined. At the same time, by optimizing the structural design of the water testing machine, the mold water testing becomes more convenient, efficient and accurate.

[0023] Among them, the gas pressurizing mechanism includes a pneumatic pressurizing valve 4 installed on the water storage tank 1, the pneumatic pressurizing valve 4 is connected to the upper part of the water storage tank 1 through a gas pressurizing pipe 5, and the compressed air enters from the air inlet of the pneumatic pressurizing valve 4. The pneumatic pressurizing valve 4 pressurizes the gas by controlling the air supply and exhaust of the air source. At the same time, a one-way check valve 6 is installed on the gas pressurizing pipe 5 to prevent gas backflow.

[0024] Moreover, an air outlet 7 is also provided on the upper part of the water storage tank 1. After the air outlet 7 is opened, the pressure of the water storage tank 1 and the water pipe 2 connected to the mold can be released, so that the water storage tank 1 and the water pipe 2 connected to the mold can be used repeatedly.

[0025] The working principle of the utility model is as follows: when testing water, the mold water pipe 2 is connected to the mold water circuit, and then the air is introduced into the water storage tank 1 through the pneumatic pressure valve 4 to increase the pressure. The pressurized water can enter the mold through the mold water pipe 2 for water testing. The water pressure in the mold will change with the air pressure in the water storage tank 1. After pressurization, the sealing of the mold water circuit can be tested. The sealing of the mold water circuit can be tested with high-pressure water. If the pressure gauge 8 detects a pressure drop, it means that the sealing of the mold water circuit is abnormal. By checking the leaking position of the mold, the leaking position can be accurately determined.

[0026] In summary, this technical solution pressurizes the water channel through gas, which can quickly monitor the leakage location of the mold water channel. It has high detection efficiency, fast speed, good reliability, and high detection accuracy. It can effectively shorten the time of mold water testing and improve the accuracy of water testing, making mold water testing more convenient, efficient and accurate, and its structure is relatively simple and the production cost is low.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
