Description

Technical Field

[0001] This utility model relates to the field of thermally conductive silicone production technology, and in particular to a molding device for producing thermally conductive silicone. Background Technology

[0002] In the molding device of a thermally conductive silicone production line, its core function is to mold uniformly mixed silicone raw materials into products of predetermined specifications through precise pressure and temperature control. This device first ensures that the silicone material is fully filled into the mold cavity, eliminating air bubbles and voids to guarantee uniform density of the molded product. Secondly, through a controlled pressurization process, the silicone molecular chains are tightly aligned, thereby improving its thermal conductivity and mechanical strength. The molding stage also requires stable heat conduction to ensure the silicone forms a stable cross-linked structure during curing, preventing deformation or cracking. Furthermore, the device can adapt to product requirements with different hardness or thickness by adjusting pressure parameters, achieving flexible production. The final molded silicone parts must have a smooth surface and precise dimensions to meet the stringent requirements of interface materials in scenarios such as heat dissipation for electronic devices. The entire molding process directly determines the physical performance stability and batch consistency of the product, making it a crucial link in the production line connecting raw material preparation and subsequent processing.

[0003] Existing molding devices for producing thermally conductive silicone have shortcomings in use. They cannot slit the thermally conductive silicone during the molding process, nor can they automatically eject the slit material after slitting.

[0022] In this embodiment, the molding assembly 3 includes a molding push rod 301, a mounting plate 302, a pressing block 303, and a guide rod 304. The movable end of the molding push rod 301 is fixed with the mounting plate 302. The lower side of the mounting plate 302 is provided with the pressing block 303. The pressing block 303 has a grid clearance groove that cooperates with the slit grid 204. The guide rod 304 is installed on the back side of the mounting plate 302.

[0023] In this embodiment, the auxiliary pressure-bearing component 4 includes a pressure-bearing push rod 401, a pressure-bearing block 402, and a guide block 403. The pressure-bearing push rod 401 is equipped with the pressure-bearing block 402 at its movable end, and the pressure-bearing block 402 is equipped with the guide block 403 at its side end.

[0024] In this embodiment, the material pushing assembly 5 includes a top material push rod 501, a top plate 502 and a push rod 503. The movable end of the top material push rod 501 is equipped with a plurality of push rods 503 via the top plate 502. The positions of the push rods 503 correspond one-to-one with the positions of the movable block 207.

[0025] In this embodiment, the mold support 1 includes a lower horizontal plate 101, a vertical plate 102, an upper horizontal plate 103, a support column 104, and a middle horizontal plate 105. The vertical plate 102 and the support column 104 are fixed to the upper side of the lower horizontal plate 101.

At this time, the movable tray 205 is in the initial position, and the compression spring 209 on the support rod 208 is in the natural state.

[0028] 2. Molding process: The controller controls the action of the molding assembly 3. The molding push rod 301 pushes the mounting plate 302 downward, and the mounting plate 302 drives the pressure block 303 downward to apply pressure to the thermally conductive silicone in the material loading groove 203.

[0030] At the same time, the auxiliary pressure-bearing component 4 starts to work. The pressure-bearing push rod 401 pushes the pressure-bearing block 402 to move upward. The guide block 403 slides in the guide groove 106 of the vertical plate 102 to ensure that the pressure-bearing block 402 moves vertically upward, providing auxiliary support for the edge of the material-carrying component 2 and ensuring the stability of the device during the molding process.

[0031] 3. Material feeding process: After the molding is completed, the controller controls the pusher assembly 5 to move. The pusher rod 501 pushes the top plate 502 to move upward. The top plate 502 drives several push rods 503 to move upward. After the push rods 503 pass through the through hole 108 of the middle horizontal plate 105, they push the movable block 207 upward.

[0032] The movable block 207 slides upward in the movable groove 206, and pushes the movable pallet 205 upward through the support rod 208, pushing out the slit material in the grid area of ​​the slit grid 204, thus realizing the automatic material pushing function.

[0033] 4. Reset and prepare for the next molding: After the material is pushed out, each component is reset under the control of the controller. The flip motor 201 can drive the rotating plate 202 to flip, and rotate the material loading tank 203 to a suitable position to prepare for the next silicone raw material placement and molding operation.
