Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of high-pressure resin mold detection, and particularly relates to a resin mold material performance detection equipment. BACKGROUND

[0002] In the ceramic production industry, high-pressure resin molds are widely used. The high-pressure resin mold has low cost and high production efficiency for producing ceramic products. The high-pressure molding process is entering the industrialization stage.

[0003] The high-pressure molding process refers to applying pressure to the slurry filled in the mold during the grouting process to remove water and make the slurry quickly dehydrate and harden. The performance of the high-pressure resin mold has a decisive influence on production. In order to evaluate the advantages and disadvantages of the high-pressure resin mold material, the high-pressure resin material is detected to obtain the raw material ratio and optimize the production process.

[0004] The detection of the high-pressure resin material usually adopts the method of making a detection sample block to estimate the performance of the mold through the detection experiment. The common detection items are water permeability detection and slurry thickness detection, which are important indicators of the performance of the mold.

[0005] The detection equipment in the prior art has the following defects: 1) each detection equipment is usually an independent equipment, which can only perform water permeability detection or slurry thickness detection. After all the sample blocks are detected in one way, they are transported in batches to the next equipment for other detection; 2) the detection equipment needs to be manually operated to control the detection water flow and air pressure during the detection experiment. Manual control not only wastes time but also cannot accurately control the water pressure and air pressure during detection, resulting in greater measurement error. Moreover, manual operation cannot simulate the actual production conditions; 3) the service life of the resin mold is usually 20,000 to 30,000 times. Manual detection cannot completely simulate the actual production conditions, so the accurate detection of the service life cannot be realized. SUMMARY

[0044] The pipeline in the scheme refers to the conveying pipe and the drain pipe 63, and the pipeline for conveying detection water and conveying detection gas is collectively referred to as a conveying pipe, and can be a PU hose.

[0045] The working process of the high-pressure resin mold performance detection equipment provided by the application is as follows: I) water permeability detection mode: 1) Place the sample block 15 on the bottom compression plate 2901 so that the sample block 15 uniformly covers the O-ring 2905.

[0046] 2) Then press the sample block 15 by the hexagonal head bolt 2903 to make the top compression plate 2902 press the sample block 15, and place the first compression device 29 with the sample block 15 on the drainage tank 60.

[0047] 3) The control system selects the water permeability detection mode, the buzzer sounds, and the three-color display lamp 10 displays green, waits, and when the display lamp 10 turns yellow, the test is over, and the result is the water permeability of the sample block 15.

[0048] The specific detection process of the equipment is as follows: ① The water permeability detection mode is started, and the pressure in the water tank 24 is detected by the pressure transmitter 27; ② The water tank 24 is opened, and the water tank 24 is pressurized by the gas source 30, the gas tank 35 and the third pressure reducing valve 44, so that the water pressure output by the water tank 24 reaches the set value (in the range of 0-1MPa), the conveying pipe is connected with the C-shaped quick connector 2904 on the water tank 24 and the first compression device 29, and the detection water is injected into the first compression device 29; ③ The equipment injects water into the sample block 15 for 90s, and the water tank 24 reaches the set water pressure and stabilizes due to pressurization, and the sample block 15 is filled with water, during which the pneumatic coaxial valve 64 controls the transition drainage chute 62 to be in an open state, and no water is stored in the transition drainage chute 62 during the water injection process; ④ After 90 seconds, the water tank 24 stops filling water and begins testing the water permeability of the sample block: the air-controlled coaxial valve 64 controls the transition drainage bucket 62 to be closed, and the device counts for 60 seconds. During this 60-second period, the test water that permeates the sample block 15 is stored in the transition drainage bucket 62. The electronic scale 61 weighs and counts the water in the transition drainage bucket 62. At the end of 60 seconds, the weight increase on the electronic scale 61 displayed by the device is the water permeability result. ⑤ The water tank 24 is depressurized by the solenoid valve, and the water pressure in the water tank 24 is restored to 0. The transition drainage bucket 62 is opened to drain the water.

[0049] 2) After the water permeability test, in the actual production process, after the resin mold produces a certain amount of green bodies, the mold will be maintained, that is, the mold will be washed. In order to simulate the actual use status of the mold in production, this solution designs a washing mode, and its specific process is: After the water permeability test is completed, click the touch screen 8 to switch the water permeability mode to the "washing mode" to start washing. During the washing process, the solenoid valve behind the second pressure reducing valve 43 and the solenoid valve at the water outlet of the water tank 24 control the alternating water and air flow to the sample block 15. For example, after one minute of water flow, one minute of air flow, and then water flow again for the next cycle. The water flow and air flow time and the number of washing cycles can be set arbitrarily; the drainage water bucket is in the open state throughout the washing process, which can realize the production situation of multiple washing of the mold in actual production. Even if the mold is washed thousands of times, the equipment can be carried out independently.

[0050] 3) Pulp Thickness Detection Mode: 1) Place the sample 15 on the first compression plate 3601, place the compression cylinder 3609 in the center of the sample 15, and align the second through-hole of the second compression plate 3603 with the first through-hole of the first compression plate 3601. Secure the sample 15 between the two compression plates using the first tension bolts 3602. Place the cylinder cover 3605 on the upper end of the compression cylinder 3609 and secure it to the second compression plate 3603 using the second tension bolts 3604. Ensure that all bolts are in a relatively stable state to ensure that the equipment can withstand a maximum air pressure of 1 MPa without collapsing, thereby ensuring the safety of the experimenter.

[0051] 2) Place the second compactor 36 with the sample 15 in the tray 14 and then fasten the protective cover 13. Connect the female thread equal diameter tee 3606 to the delivery pipe and then to the air source 30. Close the manual switch valve 3607 and adjust the first pressure reducing valve 41 to the required test pressure. At this time, select the pulp feeding screen on the touch screen 8 and click to start the pulp feeding thickness test. The test will end after five minutes and the test results can be read. 3) After the test, open the manual switch valve 3607 to release the pressure before disconnecting the delivery pipe from the equal-diameter tee joint 3606, so as to prevent the atmospheric pressure from causing harm to the experimenters. After releasing the pressure, the delivery pipe can be removed, and the second pressure device can be disassembled for the next sample detection.
