Description

Technical Field

[0001] This utility model relates to the field of silicone mold technology, and in particular to a silicone mold for a suction resistance test tray. Background Technology

[0002] A suction resistance test tray is a device or tool used to test the suction resistance properties of materials. It measures a material's ability to absorb moisture under pressure and is typically used to evaluate properties such as air permeability and filtration efficiency. By using a suction resistance test tray, it is possible to ensure that materials meet expected performance standards in practical applications, thereby improving product quality and reliability. Silicone molds for suction resistance test trays are commonly used in laboratories or production processes to test the moisture absorption and air permeability of materials.

[0003] However, the existing silicone molds for suction resistance testing trays are not convenient for real-time monitoring of humidity and air pressure inside the mold, making it difficult to judge the performance of the test material in real time. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a silicone mold for a suction resistance test tray to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a silicone mold for a suction resistance test tray, including a lower mold for accommodating materials for testing, an upper mold for sealing the lower mold, a cavity for placing test materials inside the lower mold, a sensor group for detecting humidity and air pressure fixedly installed at the bottom of the cavity, a support cover for protecting the sensor group on one side, the sensor group being signal-connected to a main control unit for automated control, the main control unit being signal-connected to a display screen for displaying data, an air inlet for guiding air inside the upper mold, an air pressure sensor for detecting the air pressure inside the upper mold on one side of the air inlet, and a miniature air pump for supplying gas fixedly installed on the other side of the air inlet.

[0006] Preferably, in any of the above solutions, guide rods for guiding and supporting are provided at the four corners of the lower mold, and guide sleeves that fit with the guide rods are provided at the four corners of the upper mold.

[0007] The above technical solution achieves precise mold closing between the lower and upper molds via guide rods and guide sleeves at the four corners. This ensures that the upper mold can accurately close with the lower mold, forming a sealed mold cavity. This guarantees the stability and accuracy of the testing process. The mold cavity provides space for the test material, allowing it to be placed flat and in full contact with the inner wall, preventing gas leakage from affecting the test results. The air inlet, pressure sensor, and micro air pump inside the upper mold work together. The air inlet provides a channel for gas to enter the mold cavity. Under the control of the main control unit, the micro air pump can precisely adjust the gas supply according to the testing requirements. The pressure sensor monitors the changes in air pressure inside the upper mold in real time, providing data for evaluating the absorption resistance performance of the test material.

[0008] Preferably, in any of the above embodiments, the sensor group includes a detection support base for support, a humidity sensor for humidity detection, and a barometric pressure sensor for barometric pressure detection. The humidity sensor and the barometric pressure sensor are fixedly installed on the top of the detection support base. The humidity sensor is located on one side of the barometric pressure sensor. The humidity sensor and the barometric pressure sensor are signal connected to the main control unit. Connecting blocks are fixedly installed at both ends of the detection support base to engage and secure it.

[0009] The above technical solution employs the following: the detection support base provides a stable mounting foundation for the humidity sensor and the air pressure sensor, ensuring that the sensors remain in a fixed position during testing. The humidity sensor and the air pressure sensor monitor the humidity and air pressure within the mold cavity in real time and transmit the data to the main control unit. The humidity sensor can accurately measure the moisture absorption of the test material during the absorption resistance test, providing a basis for evaluating the material's hygroscopicity. The air pressure sensor, in conjunction with the air pressure sensor at the bottom of the upper mold, calculates the material's air permeability and airtightness by measuring the air pressure difference between the upper and lower ends of the mold cavity, providing strong support for real-time assessment of the test material's performance.

[0010] Preferably, in any of the above embodiments, the connecting block includes a connecting spring that provides power and a disassembly block that engages with the detection support. The connecting spring is fixedly installed inside the detection support, and one end of the connecting spring is fixedly installed with the disassembly block that moves inside the detection support. One end of the disassembly block is provided with a manually operated toggle block.

[0011] The above technical solution is adopted: the connecting spring provides elastic support for the disassembly block. Under normal installation conditions, the elastic force of the connecting spring causes the disassembly block to be inserted into the corresponding slot of the lower mold or other fixed structure, which firmly fixes the sensor group in the designated position. When it is necessary to disassemble the sensor group, the push block at one end of the disassembly block is manually operated to overcome the elastic force of the connecting spring and make the disassembly block disengage from the slot, so that the sensor group can be easily removed for maintenance, replacement or calibration.

[0012] Preferably, in any of the above embodiments, the support cover includes an electric telescopic rod connected to the main control unit and a protective cover that shields the humidity sensor and the air pressure sensor. The electric telescopic rod is fixedly installed on the top of the detection support base, and a protective cover that moves inside the lower mold is fixedly installed on the top of the electric telescopic rod. Several ventilation holes are provided around the protective cover.

[0013] The above technical solution employs an electric telescopic rod controlled by the main control unit to raise and lower the protective cover. During testing, the protective cover descends under the push of the electric telescopic rod, covering the sensor assembly and shielding the humidity sensor and pressure sensor to prevent test materials or other impurities from entering the sensors and affecting measurement accuracy. Simultaneously, ventilation holes around the protective cover ensure normal gas flow within the mold cavity, without affecting the sensors' monitoring of air pressure and humidity. When test materials need to be removed, the electric telescopic rod raises the protective cover; the thrust generated by the rising cover further assists in pushing the test materials out of the mold cavity, facilitating material removal and improving the convenience and efficiency of mold use.

[0014] Preferably, in any of the above solutions, the display screen is fixedly installed at one end of the lower mold, and the display screen is located on one side of the mold cavity.

[0015] Preferably, in any of the above embodiments, the pressure sensor is fixedly installed at the bottom of the upper mold, and the micro air pump is fixedly installed at the top of the upper mold.

[0016] The above technical solution is adopted: the display screen is connected to the main control unit to display the data. The main control unit processes and analyzes the data collected by the sensor group and the air pressure sensor, and displays the results on the display screen in the form of intuitive numbers, charts or curves. The tester can directly obtain the key performance parameters of the test material such as humidity and air pressure difference from the display screen, and understand the absorption resistance performance of the test material in real time.

[0018] 1. An adjustable support cover is installed inside the silicone mold to protect the sensor group that detects humidity and air pressure. An air pressure sensor is installed on the top of the mold to detect the air pressure at the top and bottom of the material inside the mold. The air pressure difference is used to determine the air permeability and airtightness of the material, which facilitates real-time monitoring of the material's moisture absorption and air permeability.

The mold cavity 3 provides a space for the test material, allowing the test material to be placed flat and fully contact the inner wall inside the mold cavity 3, avoiding gas leakage from affecting the test results. The air inlet 6, the air pressure sensor 7 and the micro air pump 8 inside the upper mold 2 work together. The air inlet 6 provides a channel for gas to enter the mold cavity 3. Under the control of the main control unit, the micro air pump 8 can accurately adjust the gas supply according to the test requirements.

During testing, the protective cover 52 descends under the push of the electric telescopic rod 51, covering the sensor group 4 and shielding the humidity sensor 42 and the air pressure sensor 43 to prevent test materials or other impurities from entering the sensors and affecting measurement accuracy. Simultaneously, the ventilation holes around the protective cover 52 ensure normal gas flow within the mold cavity 3, without affecting the sensor's monitoring of air pressure and humidity. When it is necessary to remove the test material, the electric telescopic rod 51 can raise the protective cover 52.
