Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wave-absorbing materials, and particularly relates to a mold device for testing wave-absorbing materials. BACKGROUND

[0002] Wave-absorbing materials are materials that can absorb or greatly weaken electromagnetic waves received on their surfaces, thereby reducing electromagnetic wave interference. In engineering applications, in addition to the requirement that wave-absorbing materials have high absorption rates for electromagnetic waves in a wide frequency band, they are also required to have light weight, temperature resistance, moisture resistance, corrosion resistance, and other properties. With the development of modern science and technology, the influence of electromagnetic wave radiation on the environment is increasing. At airports, electromagnetic wave interference can cause flights to be delayed; at hospitals, mobile phones can often interfere with the normal operation of various electronic diagnostic instruments. Therefore, addressing electromagnetic pollution and finding a material that can resist and weaken electromagnetic wave radiation, i.e., wave-absorbing materials, has become a major issue in materials science. Electromagnetic radiation can cause direct and indirect harm to the human body through thermal effects, non-thermal effects, and cumulative effects. Research has shown that wave-absorbing materials with good performance have characteristics such as high absorption frequency, high absorption rate, and thin matching thickness. The application of such materials in electronic devices can absorb leaked electromagnetic radiation, achieving the purpose of eliminating electromagnetic interference. According to the law of electromagnetic wave propagation from low magnetic permeability to high magnetic permeability in a medium, high magnetic permeability is used to guide electromagnetic waves, absorb a large amount of electromagnetic wave radiation energy through resonance, and then convert the electromagnetic wave energy into heat energy through coupling.

Detailed Implementation

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] Example 1 like Figures 1 to 7 As shown in the figure, a mold device for testing microwave absorbing materials in this embodiment includes a mold base plate 1.

[0018] Because the absorbing material patches are designed to meet product requirements, it is necessary to measure and position the patches at different lengths and widths. Currently, there is a lack of mold equipment for adjusting and fixing the length and width of the absorbing material patches for measurement. This application employs an adjustable testing mechanism to position the absorbing material patches of different lengths and widths according to product needs, facilitating the measurement of length and width.

[0019] The innovation of this application lies in the inclusion of an adjustment testing mechanism 2, which is installed on the bottom surface of the mold and positioned according to the length and width requirements of the test absorbing material patch 100. The adjustment testing mechanism 2 includes a threaded transmission rod 21, a threaded portion 29, a connecting plate 3, and a positioning component 4. The threaded transmission rod 21 is axially connected to the bottom plate 1 of the mold and has a movable opening 12 on the upper surface of the bottom plate. The front and rear ends of the threaded transmission rod 21 are respectively provided with a shaft portion 22 and a shaft portion 23 equipped with ball bearings. The bottom plate 1 of the mold has a transmission cavity 11 relative to the movable opening 12. Within the transmission cavity 11 are shaft tubes 24 and 2 for axially connecting shaft portion 22 and shaft portion 23. A stud 26 is provided at the outer end of shaft portion 22, and a flange nut 27 is installed on the stud 26. An operating handle 28 is provided at the outer end of the stud 26. The threaded portion 29 is screwed onto the threaded transmission rod 21 for transmission. The threaded portion 29 is adjusted according to the length of the test absorbing material patch 100 by manually operating the threaded transmission rod 21, and is fixed by the flange nut 27. A connecting plate 3 is inserted into the threaded portion 29. Both the threaded portion 29 and the top surface of the roller 34 are provided with insertion tubes 31, and the bottom surfaces of the connecting plate 3 are respectively provided with insertion posts 32 for inserting the insertion tubes 31. The insertion posts 32 can be fitted with rubber sleeves for easy assembly of the connecting plate 3 and convenient maintenance. The connecting plate 3 has an adjustment port through it, which facilitates manual adjustment, movement and fixation of the two positioning components 4. There are two positioning components 4, which are movably installed in the adjustment port. The positioning components 4 are adjusted and installed on the connecting plate 3, and the other end of the connecting plate 3 is fitted with a roller 34. The mold base plate 1 has a wheel rail 13 for the movement of the roller 34, so that the movement of the connecting plate 3 is stable.

[0020] In this application, the positioning component is an assembly structure. The positioning component 4 includes a column 41, a positioning plate 42, and a handle 43. The handle 43 is located at the top of the column 41, and the positioning plate 42 is installed at the bottom of the column 41. The upper surface of the positioning plate 42 has an internal thread 44 at its center. The column 41 is threaded 45, with the thread 45 at its bottom used to install the positioning plate 42. Other threads 45 pass through the adjustment port and are fixed in position by a fixing nut 46. This facilitates the assembly and replacement of different positioning plates 42.

[0021] A limiting plate 5 is provided between the moving port and the outer end of one side of the roller rail. A width measuring scale 51 for assisting in measuring the width of the absorbing material patch is located at one end of the limiting plate 5, and the width measuring scale 51 increases from front to back. A length measuring scale 52 for assisting in measuring the length of the absorbing material patch is located on the outer side of the roller rail. The length measuring scale 52 increases from right to left (e.g., ...). Figure 1 (As indicated by the arrow), when measuring the test absorbing material patch 100, one end is positioned inside the front end of the limiting plate 5, and the two outermost corners are positioned by two positioning components. This facilitates reading through the width measurement scale 51 and the length measurement scale 52.

[0022] Working principle: When using it, as follows Figure 1 As shown, one end of the test absorbing material patch 100 is placed inside the front end of the limiting plate, aligned with the front end of the width measurement scale, and its length is aligned with the rightmost end of the length measurement scale. The threaded drive rod is operated to move the connecting plate via the threaded portion. The other end of the connecting plate moves within the wheel rail via the inserted guide wheel, and the threaded drive rod is fixed to the edge of the other end of the test absorbing material patch by a flange nut. Then, the two positioning components are manually moved and pressed against the two corners of the other end of the test absorbing material patch. Readings are then taken from the width and length measurement scales.
