Description

TECHNICAL FIELD

[0001] The one or more embodiments of the present specification relate to the technical field of automobile part manufacturing, and in particular to a mold water pipe testing device and a water pipe testing system. BACKGROUND

[0002] Since the 1990s, the increasingly stringent regulations of automobile environmental protection, safety and energy saving technology and the continuous improvement of user requirements for automobile products have become the basic driving force for the technological progress of today's automobile products. As the most commonly used automobile body structure material, the position of steel materials, whether in the whole body or in special purposes, has been greatly challenged by low-density materials such as aluminum, plastic and magnesium. And this challenge also prompted the steel industry to develop new steel grades, making the automobile lighter, safer and better in performance, and competing with low-density materials in the competition of low-cost body structure materials.

[0003] When producing automobile parts, a mold needs to be used for manufacturing. Before the mold is used, the functions of the mold need to be detected to confirm whether the water pipe system in the mold is normal.

[0004] However, the applicant finds that the prior art at least has the following problems:

[0005] Water is used to test the water pipe. If the water pipe is unqualified and bursts, the water in the water pipe will be sprayed to the working site, causing damage to the site environment. SUMMARY

[0006] Therefore, the one or more embodiments of the present specification aim to provide a mold water pipe testing device to solve the problem that water is used to test the water pipe. If the water pipe is unqualified and bursts, the water in the water pipe will be sprayed to the working site, causing damage to the site environment.

[0007] To achieve the above purpose, the one or more embodiments of the present specification provide a mold water pipe testing device, which comprises an outer shell, a containing cavity is arranged in the outer shell, a water storage cavity and a detection cavity are installed in the containing cavity, water is filled in the water storage cavity, a first water pump is installed in the water storage cavity, the first water pump is connected with a first water pipe, the first water pipe is connected with a water inlet pipe, the water inlet pipe is connected with a water inlet joint, the water inlet joint is connected with an upper mold, a lower mold is installed below the upper mold, a base is installed at the bottom of the lower mold, a communication pipe is connected between the upper mold and the lower mold, a water outlet joint is further installed on the upper mold, a water outlet pipe is connected with the water outlet joint, the water outlet pipe is communicated with the detection cavity, and a liquid level switch is arranged in the detection cavity.

[0008] Optionally, the water outlet pipe is communicated with a pressure measuring U-shaped pipe, the vertical part of the pressure measuring U-shaped pipe is telescopic, a pressure measuring sensor is installed at the bottom of the pressure measuring U-shaped pipe, and a pressure marking sensor is installed in the water outlet pipe.

[0009] Optionally, the water inlet pipe is connected to a vent pipe, the vent pipe is connected to an air pump, the air pump is installed in the accommodating cavity, a vent is provided on the accommodating cavity, and a shut-off valve is provided on the water outlet joint.

[0010] Optionally, a second water pump is installed in the detection chamber, and the second water pump pumps the water in the detection chamber back into the water storage chamber.

[0011] Optionally, a first valve is installed on the ventilation pipe, and a second valve is installed on the first water pipe.

[0012] A water pipe detection system, comprising:

[0013] Pre-module and detection module;

[0014] The front module includes a filling unit, a capacity measuring unit and a calculation unit;

[0015] The filling unit fills the water pipe testing device in the mold with liquid;

[0016] The volume measuring unit detects the pressure on the pipe wall at the lowest point and the pressure on the highest point of the water pipe using a pressure measuring U-tube according to the result of liquid filling;

[0017] The calculation unit calculates the pressure difference based on the pressure on the pipe wall at the lowest point and the pressure on the highest point of the water pipe;

[0018] The detection module includes an inflation unit, a pressure measuring unit and a judgment unit;

[0019] The inflation unit inflates the water pipe to be tested, and the inflation pressure is the maximum water pressure plus the pressure difference;

[0021] The judging unit judges the state of the water pipe to be tested based on the detection result of the pressure measuring unit, and judges whether the water pipe is leaking or bursting.

[0022] From the above description, it can be seen that an in-mold water pipe testing device provided by one or more embodiments of the present specification detects the pressure difference between the lowest and highest points of the water pipe to be tested, thereby compensating for the pressure on the pipe wall caused by the gravity of water during the gas filling test, so that the internal air pressure of the water pipe reached by inflation is the same as the maximum pressure on the pipe wall when it is filled with water, thereby detecting the pressure-bearing capacity of the water pipe and avoiding water-filling detection. When the water pipe fails to meet the requirements, water splashes onto the work site, causing on-site pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] According to the water pipe detection device described above, this specification also provides a water pipe detection system, including a front module 001 and a detection module 002;

[0034] The front module 001 includes a filling unit 011, a capacity measuring unit 012 and a calculation unit 013;

[0041] The judging unit 023 judges the state of the water pipe to be tested based on the detection result of the pressure measuring unit 022, and determines whether the water pipe is leaking or bursting.

[0042] The working principle of the present invention is as follows: when in use, the water in the water storage chamber 103 is pumped into the water inlet joint 205 through the water inlet pipe 104 until the water flows into the detection chamber 113 from the water outlet pipe 105. When a certain amount of water is pumped into the detection chamber 113, the liquid level switch is triggered and the water pumping is stopped, indicating that the water pipe can be used normally under normal pressure. If the liquid level switch is not triggered, the water pipe leaks, indicating that the water pipe is unqualified, and the water pumping is stopped at the same time to avoid water spraying. Since the water pressure in the upper mold 203 and the lower mold 202 is low from beginning to end, it can be controlled in time to avoid test water spraying. ; Extend the pressure measuring U-shaped tube 115 so that the bottom of the pressure measuring U-shaped tube 115 is at the same height as the base 201, and measure the pressure difference between the lowest point of the water pipe in the equipment to be tested and the pressure affected by the gravity of the water and the pressure at the water outlet of the water pipe; obtain the pressure difference between the lowest point of the water pipe and the pressure affected by the gravity of the water and the pressure at the water outlet of the water pipe, and then pump gas into the mold to be tested to test whether the water pipe meets the requirements under the maximum water pressure plus the pressure difference. Compensate for the influence of the gravity of the water on the water pressure compared to the air pressure at the same pressure. By using gas detection, even if the water pipe breaks, it will not cause the problem of water splashing on the site.
