The potting adhesive is poured at the corresponding position to achieve the encapsulation of electronic devices while having good thermal conductivity.

[0003] When producing the thermally conductive potting adhesive, it is necessary to detect its hardness. The potting adhesive is injected into the corresponding mold tooling, and after waiting for it to solidify, it is taken out. This is the current process flow of sample preparation. However, the size requirements of the samples are different, which leads to the need for many different toolings to meet the requirements, increasing the cost and delaying the production efficiency due to the replacement of different toolings. Therefore, a tooling for preparing a hardness sample of a thermally conductive potting adhesive is proposed. Content of the Utility Model

[0014] The present utility model will be further described below with reference to the drawings.

[0015] Please refer to Figures 1-3 , a hardness specimen preparation tooling for a heat-conducting potting adhesive of the present utility model, includes a processing table 1, an installation groove 2 is opened in the middle of the top side wall of the processing table 1, a movable plate 3 is arranged inside the installation groove 2, an injection groove 4 is opened in the middle of the movable plate 3, a top plate 5 is arranged inside the injection groove 4, a vertical plate 6 is fixedly connected to one side side wall of the processing table 1, the vertical plate 6 is of an L-shaped structure, and a detachable injector 7 is connected to the horizontal end of the vertical plate 6, and the bottom end of the injector 7 corresponds to the center point of the top plate 5;

[0016] A screw rod 13 is fixedly connected to the middle of the bottom side wall of the top plate 5. The screw rod 13 is sequentially inserted through the bottom side walls of the movable plate 3 and the processing table 1 through its end away from the top plate 5. A driven gear 12 is rotatably arranged in the bottom side wall of the processing table 1. The driven gear 12 is of an annular structure, and threaded teeth are provided on the inner peripheral wall. The driven gear 12 is threadedly sleeved on the screw rod 13 through the threaded teeth. One side of the driven gear 12 is meshed and connected with a driving gear 8. One side of the driving gear 8 extends out of the side wall of the processing table 1. The top plate 5 is telescopically and movably connected to the injection groove 4 through the screw rod 13.

[0017] The technical effect of this solution is as follows: Rotate the driving gear 8 as needed to drive the driven gear 12 to rotate, drive the screw rod 13 to drive the top plate 5 to lift and lower synchronously, adjust the depth of the injection groove 4 to the required size, and then inject the material into the injection groove 4 through the injector 7. In this way, the function of producing various samples with different sizes can be realized by one device, reducing the number of traditional production toolings required, reducing production costs, and effectively improving the production and processing efficiency because there is no need to replace toolings. Moreover, the adjustment process is relatively convenient.

[0018] Heating sheets 10 are inlaid and connected around the injection groove 4 in the movable plate 3. A vibration motor 9 is inlaid and connected inside the center point of the top plate 5 and close to the top side wall. The four side walls of the vibration motor 9 are in contact with the inner wall of the injection groove 4. Springs 11 are fixedly connected to the bottom side walls of the installation groove 2 and close to the four corners. The top ends of the springs 11 are fixedly connected to the bottom side wall of the movable plate 3. The movable plate 3 is telescopically and movably connected to the installation groove 2 through the springs 11.

[0019] The technical effect of this solution is as follows: In order to facilitate demoulding, after the sample solidifies, press the injection groove 4 to press the injection groove 4 into the installation groove 2. Because the top plate 5 is supported by the screw rod 13, the downward pressure of the movable plate 3 will not drive the top plate 5, but the position of the top plate 5 remains unchanged. In this way, the solidified sample can be removed from the injection groove 4, which is convenient for the staff to take and place, reduces the time consumed for demoulding, and improves the overall processing speed.

[0020] Specifically, when the utility model is in use, materials are injected into the injector 7 through a hose, and then the materials are injected from the injector 7 into the injection groove 4 and fall on the top plate 5 by means of pressurization such as air pressure. The top plate 5 is adjusted to a suitable position in advance through the linkage of the driving gear 8 and the driven gear 12. To ensure the uniform distribution of the materials, a vibration motor 9 is connected inside the top plate 5. Through vibration, the air bubbles in the materials can be eliminated and the distribution of the materials on the top plate 5 can be made more uniform, ensuring the flatness of the size of the sample after production and avoiding inaccurate detection data caused by problems with the sample. After the sample solidifies, the movable plate 3 is pressed into the installation groove 2, so as to take out the sample from the injection groove 4. After the staff removes the sample, the pressing on the movable plate 3 is released, and it returns to its original position under the drive of the spring 11. The whole process is flexible and convenient to operate, which can reduce production costs and improve processing efficiency.

[0021] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the utility model.

[0022] The other parts not detailed in the utility model belong to the prior art, so they will not be elaborated here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
