Description

Technical Field

[0001] The utility model relates to the field of phenolic molding material performance testing equipment, in particular to a phenolic molding material moisture resistance testing box. Background Art

[0002] Phenolic molding compound is a thermosetting plastic mainly composed of phenolic resin and filler. During the manufacturing process, wood powder, clay or other types of inert fillers are usually added to enhance its physical properties and improve processing characteristics.

[0003] In certain application scenarios, phenolic molding compounds may be exposed to high humidity or water for a long time. Moisture absorption may cause the material's mechanical properties, such as tensile strength and flexural strength, to deteriorate. In order to ensure that the material can maintain its structural integrity and functionality under these conditions, it is crucial to test its moisture resistance. However, the existing method for testing the moisture resistance of phenolic molding compounds is to select a suitable sample, record the initial size and weight, determine the immersion temperature and time, and then take out the sample to measure the size and weight. However, during the test process, it is usually necessary to place the samples that require different immersion times in different test chambers so that each set of data does not interfere with each other during the test. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a phenolic molding material moisture resistance test box that can more efficiently test the moisture resistance of phenolic molding materials under different conditions by placing multiple samples in different test drawers and then placing them in the box.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a box body extending left and right in the length direction, a soaking chamber is provided in the box body, and also includes a plurality of test drawers, the soaking chamber includes a plurality of soaking positions, the number of the test drawers is the same as the number of the soaking positions, the box body is provided with protruding partitions between each soaking position, and each of the test drawers is fixed with handles that are against the box body on the front and back sides, and the box body is provided with a through slot corresponding to each handle.

[0006] The utility model is further configured as follows: limit modules are installed on the left and right sides of the box body above each handle, each limit module includes a reset spring and a guide block, and a matching groove for the guide block to slide along the left and right directions is provided in the box body, one end of the reset spring is fixedly connected to the guide block and the other end is fixedly connected to the box body.

[0007] The present invention is further configured such that: each guide block is arranged in a stepped shape with a narrow upper portion and a wide lower portion, and the lower end of each guide block abuts against the upper end surface of the handle at the corresponding position.

[0008] The utility model is further configured as follows: the box body is provided with a plurality of sealing columns protruding from each immersion position, and the test drawer is provided with a sealing groove corresponding to each sealing column.

[0009] The present invention is further configured as follows: a cover plate is detachably installed on the top of each test drawer, and mating blocks are protrudingly provided on the left and right sides of the cover plate, and each mating block includes a limiting section at the bottom; the box body is provided with a mating slot corresponding to each mating block, and the box body is located in each mating slot and is provided with a positioning section that counteracts the limiting section.

[0010] The utility model is further configured as follows: each of the limiting sections is arranged in a step-shaped configuration with a narrow bottom and a wide top, and each of the positioning sections is arranged in a step-shaped configuration with a narrow top and a wide bottom.

[0011] The utility model is further configured as follows: the box body is provided with a data placement frame on the front side of each soaking position.

[0012] By adopting the above technical solution, after the samples that need to be tested for resistance are measured, they are placed in different test drawers and then loaded into the immersion chamber of the box.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 7As shown, the utility model discloses a phenolic molding plastic moisture resistance test box, including a box body 1 extending left and right in the length direction, a soaking chamber 11 is provided in the box body 1, and also includes a plurality of test drawers 2, the soaking chamber 11 includes a plurality of soaking positions 111, and the number of the test drawers 2 is the same as the number of the soaking positions 111, and the box body 1 is provided with a partition 12 protruding between each soaking position 111, and the front and rear sides of each of the test drawers 2 are fixed with a handle 21 that is against the box body 1 by integral molding, welding, etc., and the box body 1 is provided with a through groove 13 corresponding to each handle 21, and after the sample to be tested for resistance is measured and placed in different test drawers 2 and then loaded into the soaking chamber 11 of the box body 1, water or other substances required for testing moisture resistance are injected into each soaking position 111 of the soaking chamber 11. The solvent then places the test drawer 2 in the immersion chamber 11 for the required time, and then the test drawer 2 can be taken out of the box 1 by applying force to the handle 21, and then the sample in the test drawer 2 can be taken out for measurement. Due to the presence of the handle 21, each handle 21 is located in the corresponding through slot 13, so the test drawer 2 in the immersion chamber 11 is affected by the partition 12 and the handle 21 and will not move compared to the immersion pool. Since there are multiple immersion chambers 11 in the box 1 and the box 1 is provided with a partition 12 protruding between each immersion position 111, the same number of test drawers 2 as the immersion position 111 can be placed in the box 1, that is, it is possible to change a certain variable and conduct a test (such as each test drawer 2 is placed in the immersion chamber 11 for a different length of time), thereby generating multiple sets of data in one box 1 to improve the test efficiency.

[0025] Among them, the box body 1 is equipped with limit modules 14 on the left and right sides above each handle 21, and each limit module 14 includes a reset spring 141 and a guide block 142. A matching groove 15 for the guide block 142 to slide along the left and right directions is provided in the box body 1. The reset spring 141 is located in the matching groove 15. One end is fixedly connected to the guide block 142 by welding or the like, and the other end is fixedly connected to the box body 1 by welding or the like. Since one end of the reset spring 141 is fixed to the guide block 142 and the other end is fixed to the box body 1, when the handle 21 of the test drawer 2 is downwardly inserted into the passage When passing through the slot 13, it is necessary to manually push the guide blocks 142 located on the left and right sides of the slot 13 to compress the reset springs 141 fixed thereto and move them away from each other so that the handles 21 can face downward and resist against the box body 1. After the test drawer 2 is placed in the box body 1, the elasticity of the reset springs 141 that lose their force can push the guide blocks 142 to reset and the bottom of each guide block 142 will resist against the handle 21 on the corresponding side, so that accidental movement or shaking is avoided in the absence of external force, and each test drawer 2 can be stably located in the corresponding immersion position 111.

[0026] Preferably, each of the guide blocks 142 is arranged in a step-shaped manner with a narrow top and a wide bottom, and the lower end of each guide block 142 is abutted against the upper end surface of the handle 21 at the corresponding position. Since each guide block 142 is arranged in a step-shaped manner, under the action of the elastic force of the return spring 141, the side with the largest width of the guide block 142 is abutted against the handle 21, thereby stably achieving the abutment between the guide block 142 and the handle 21, and the step with a narrow top and a wide bottom effectively reduces the mass of each guide block 142, so that the guide block 142 can be pushed more smoothly and then the return spring 141 is compressed.

[0027] In addition, the box body 1 is provided with a plurality of sealing columns 16 protruding from each immersion position 111, and the test drawer 2 is provided with a sealing groove 22 corresponding to each sealing column 16. Since each sealing column 16 is located on the box body 1, when the test drawer 2 needs to be turned upward and separated from the corresponding immersion position 111, the upward moving test drawer 2 drives each sealing groove 22 to move upward and separate from the corresponding sealing column 16, thereby enabling the liquid in the test drawer 2 to converge downward into the box body 1 through each sealing groove 22, and due to the presence of the partition 12, the liquid in each immersion position 111 will not converge together, and since a large amount of liquid in the test drawer 2 passes through the sealing groove 22 to The test drawer 2 is placed in the immersion position 111, and the sealing columns 16 are inserted into the corresponding sealing grooves 22. The partition 12 is provided between the adjacent immersion positions 111 of the box body 1. Therefore, the liquid in the test drawer 2 will not flow out of the immersion position 111. When the test drawer 2 is taken out, the large amount of liquid on the sample surface can fall down, and the liquid will not flow into other immersion positions 111 to interfere with the test results in other test drawers 2.

[0028] Among them, the top of each test drawer 2 is detachably mounted with a cover plate 23 by means of bolts, snaps, etc., and the left and right sides of the cover plate 23 are protruding with matching plug-in blocks 231, and each matching plug-in block 231 includes a limiting section 2311 at the bottom. The box body 1 is provided with a matching slot 17 corresponding to each matching plug-in block 231, and the box body 1 is provided with a positioning section 18 that abuts against the limiting section 2311 in each matching slot 17. Due to the existence of the top cover plate 23 of each test drawer 2, after pouring the liquid into the test drawer 2, the cover body is installed and then It can prevent external dust and impurities from falling onto the surface of the sample in the test drawer 2, and since the cover 23 is detachably connected to the test drawer 2, unrelated personnel will not touch the sample in the test drawer 2 at will during the moisture resistance test. When the sample needs to be taken out, the handle 21 is moved upward by pushing the guide block 142 so that the liquid in the test drawer 2 flows downward out of the test drawer 2. At this time, the positioning section 18 is bent outward, so that the surface where the positioning section 18 abuts against the limiting section 2311 can be offset, and the cover 23 is driven upward to separate from the test drawer 2.

[0029] Preferably, each of the limiting sections 2311 is arranged in a step-like shape with a narrow bottom and a wide top, and each of the positioning sections 18 is arranged in a step-like shape with a narrow top and a wide bottom. Since the top width of each limiting section 2311 is the largest and the bottom width of the positioning section 18 is the largest, the surface with the largest width is in contact when the two are matched and offset. The limiting section 2311 can be stably matched with the positioning section 18, so that the cover plate 23 will not be removed without the action of external force.

[0030] Among them, the box body 1 is provided with a data placement frame 19 on the front side of each immersion position 111. The design of the data placement frame 19 is convenient for users to place relevant data labels or record sheets of samples, so as to track and record the test conditions and results of each sample.

[0031] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
