Description

Technical Field

[0001] The invention relates to the field of thermal conductive silicone extrusion, and in particular to an extrusion mechanism for thermal conductive silicone processing. Background Art

[0002] Thermally conductive silicone is a silicone made of organic silicone as the main body, with fillers, thermal conductive materials and other polymer materials added. It has good thermal conductivity and electrical insulation properties, and also has moisture-proof, dust-proof, corrosion-resistant, shock-proof and other properties, thereby improving the reliability of electronic products and extending their service life. In the processing of thermally conductive silicone, it is usually processed by extrusion.

[0003] When the traditional thermal conductive silicone extrusion mechanism is working, the paste-like thermal conductive silicone is pumped into the extrusion mechanism. The paste-like thermal conductive silicone is conducive to plasticity. After cooling, the fluidity of the thermal conductive silicone weakens. The thermal conductive silicone is extruded while cooling, but the thermal conductive silicone is easy to adhere to the extrusion mechanism. When too much thermal conductive silicone adheres, the subsequent extruded thermal conductive silicone will be incomplete, the extrusion quality will be poor, and the thermal conductive silicone will be wasted. In addition, the traditional thermal conductive silicone extrusion mechanism is not convenient for producing thermal conductive silicone of different shapes and has low applicability. Summary of the invention

[0008] As an improvement of the above scheme, the cooling assembly includes support ring 1, a water inlet ring frame, support ring 2 and a water outlet ring frame. Support ring 1 and support ring 2 are fixedly connected to the side of the cooling rotating frame close to the support frame.

The support frame is fixed with water inlet ring frame and water outlet ring frame. Support ring 1 is rotatably connected to the water inlet ring frame, and support ring 2 is rotatably connected to the water outlet ring frame.

[0009] As an improvement on the above scheme, the reciprocating extrusion assembly includes a rotating rod, a pushing plate, a limit block, a transmission slide, a sliding tube, an extrusion tube, a connecting frame and a wire saw. A rotating rod is fixedly connected to the other output shaft of the motor, a pushing plate is fixedly connected to the rotating rod, a guide groove is opened on the pushing plate, a limit block is fixedly connected to the top of the extrusion frame, a transmission slide is slidably connected to the limit block, one end of the transmission slide is located in the guide groove on the pushing plate, a sliding tube is slidably connected to the side of the extrusion frame away from the support frame, the sliding tube is fixed to the transmission slide, an extrusion tube is threadedly connected in the sliding tube, the extrusion tube is connected to the extrusion frame, the extrusion tube is connected to the extrusion frame, the end of the extrusion tube away from the extrusion frame is fixedly connected to the connecting frame, the connecting frame is connected to the extrusion tube, the end of the rotating rod away from the motor is fixedly connected to the wire saw, and the wire saw is located above the connecting frame.

[0013] The beneficial effects are: first, the coolant circulates in the cooling rotating frame, thereby cooling the thermally conductive silicone in the extrusion frame. The worker starts the motor to drive the cooling rotating frame to rotate. The rotation of the cooling rotating frame can cool the thermally conductive silicone more fully. In addition, the cooling rotating frame and the fixed frame move relative to each other, so that the cooling rotating frame breaks up larger pieces of thermally conductive silicone, thereby making the thermally conductive silicone more uniform and facilitating the subsequent extrusion of the thermally conductive silicone. The transmission slide drives the sliding tube, the extrusion tube and the connecting frame to move back and forth horizontally, so that the thermally conductive silicone is not easy to adhere to the inner wall of the extrusion tube and the connecting frame, thereby making the extruded thermally conductive silicone more complete and reducing the waste of thermally conductive silicone. The extruded thermally conductive silicone is then cut off by a wire saw. In this way, the thermally conductive silicone can be continuously extruded to improve the production efficiency of the thermally conductive silicone.

[0014] Secondly, one end of the thermal silicone is supported by a magnetic frame to facilitate the wire saw to better cut the thermal silicone. After the thermal silicone is extruded, the worker can take out the magnetic frame and then rotate the connecting frame. The connecting frame drives the extrusion tube to rotate, so that the extrusion tube can be screwed out of the sliding tube. Then, the extrusion tube and the connecting frame with grooves of different shapes inside can be replaced, which makes it easier to extrude thermal silicone of different shapes and improves the overall applicability.

[0015] Finally, when the rotating rod rotates, it will drive the pressing plate to rotate, and the pressing plate will intermittently squeeze the pressing frame, causing the upper end of the pressing frame to move downward and the lower end of the pressing frame to move upward, thereby driving the weight block to move upward. When the pressing plate no longer squeezes the pressing frame, the pressing frame resets under the action of gravity, and the pressing frame drives the weight block to move downward, causing the weight block to hit the surface of the sliding tube, causing the sliding tube and the extrusion tube to vibrate, further making it difficult for the thermal conductive silicone to adhere to the inner wall of the extrusion tube.

The support ring 1 61 and the support ring 2 63 are fixedly connected to the side of the cooling rotating frame 57 close to the support frame 55.

[0031] The reciprocating extrusion assembly includes a rotating rod 71, a pushing plate 72, a limit block 73, a transmission slide 74, a sliding tube 75, an extrusion tube 76, a connecting frame 77 and a wire saw 78. The other output shaft of the motor 4 is fixedly connected with a rotating rod 71, and the rotating rod 71 is connected to the pushing plate 72 through a flat key. The pushing plate 72 is provided with a guide groove. The top of the extrusion frame 2 is fixedly connected with a limit block 73, and the limit block 73 is slidably connected with a transmission slide 74. One end of the transmission slide 74 is located in the guide groove on the pushing plate 72. The guide groove on the pushing plate 72 is used for In order to drive the transmission slide 74 to move horizontally back and forth, a sliding tube 75 is slidably connected to the side of the extrusion frame 2 away from the support frame 55, and the sliding tube 75 is fixedly connected to the transmission slide 74. An extrusion tube 76 is threadedly connected to the sliding tube 75, and the extrusion tube 76 is connected to the extrusion frame 2.

The wire saw 78 is used to cut the thermal conductive silicone.

[0032] First, the paste-like thermally conductive silicone is pumped into the extrusion frame 2 through the injection pump 3, and the coolant is injected into the support ring 1 61 through the water inlet ring frame 62. The coolant flows through the cooling rotating frame 57 and then flows to the support ring 2 63. Then the coolant flows out through the water outlet ring frame 64, so that the coolant circulates in the cooling rotating frame 57, thereby cooling the thermally conductive silicone in the extrusion frame 2, so that the fluidity of the thermally conductive silicone is weakened. The worker starts the motor 4, and the motor 4 drives the rotating shaft 52 to rotate through one of the output shafts. The rotating shaft 52 drives the rotating block 53 to rotate through the pulley set 54, and the rotating block 53 drives the cooling rotating frame 57 to rotate. The rotation of the cooling rotating frame 57 can cool the thermally conductive silicone more fully. In addition, the cooling rotating frame 57 and the fixed frame 56 move relative to each other, so that the cooling rotating frame 57 breaks up larger pieces of thermally conductive silicone, thereby making the thermally conductive silicone more uniform, which is convenient for the subsequent better extrusion of the thermally conductive silicone. Then the thermally conductive silicone will enter the extrusion tube 76 and the connecting frame 77, and the motor 4 drives the rotating shaft 52 through another output shaft. The rotating rod 71 rotates, the rotating rod 71 drives the pushing plate 72 to rotate, and the pushing plate 72 squeezes the transmission slide 74 through the guide groove, thereby driving the transmission slide 74 to move horizontally back and forth, and the transmission slide 74 drives the sliding tube 75, the extrusion tube 76 and the connecting frame 77 to move horizontally back and forth, so that the thermal conductive silicone is not easy to adhere to the inner wall of the extrusion tube 76 and the connecting frame 77, thereby making the extruded thermal conductive silicone more complete and reducing the waste of thermal conductive silicone. The rotation of the rotating rod 71 drives the wire saw 78 to rotate. When the pushing plate 72 drives When the transmission slide 74, the sliding tube 75, the extrusion tube 76 and the connecting frame 77 move toward the extrusion frame 2, the rotating rod 71 drives the wire saw 78 to rotate to the side of the connecting frame 77, so that the wire saw 78 cuts off the extruded thermal conductive silicone. When the pushing plate 72 drives the transmission slide 74, the sliding tube 75, the extrusion tube 76 and the connecting frame 77 to move in the direction away from the extrusion frame 2, the rotating rod 71 drives the wire saw 78 to rotate to the top of the connecting frame 77. In this way, the thermal conductive silicone can be continuously extruded, thereby improving the production efficiency of the thermal conductive silicone.

[0033] Embodiment 2: Based on embodiment 1, Figure 7-Figure 9 As shown, it also includes a bracket 81 and a magnetic frame 82. The bracket 81 is fixedly connected to the extrusion frame 2. The bracket 81 is made of iron material. The magnetic frame 82 is placed on the bracket 81. The magnetic frame 82 is made of magnetic material. The magnetic frame 82 is adsorbed on the bracket 81. The connecting frame 77 is located in the magnetic frame 82. The magnetic frame 82 is used to support the connecting frame 77.

[0034] When the sliding tube 75, the extrusion tube 76 and the connecting frame 77 move toward the extrusion frame 2, the connecting frame 77 is located in the magnetic frame 82, and the connecting frame 77 will not be separated from the magnetic frame 82. The thermal conductive silicone is then cut by the wire saw 78, and one end of the thermal conductive silicone is supported by the magnetic frame 82, which facilitates the wire saw 78 to better cut the thermal conductive silicone. After the thermal conductive silicone is extruded, the worker can take out the magnetic frame 82, separate the magnetic frame 82 from the bracket 81, and separate the magnetic frame 82 from the connecting frame 77 at the same time, and then rotate the connecting frame 77, and the connecting frame 77 drives the extrusion tube 76 to rotate, so that the extrusion tube 76 can be screwed out of the sliding tube 75, and then replace the extrusion tube 76 and the connecting frame 77 with grooves of different shapes inside, and then screw the replaced extrusion tube 76 and the connecting frame 77 into the sliding tube 75, and then put the magnetic frame 82 back on the replaced connecting frame 77, and the magnetic frame 82 is re-adsorbed on the bracket 81, so as to facilitate the extrusion of thermal conductive silicone of different shapes and improve the overall applicability.

[0035] Embodiment 3: Based on embodiment 2, Figure 7 As shown, a cooling component is also included. The cooling component is arranged on the extrusion frame 2 and is connected to the sliding tube 75. The cooling component includes a mounting frame 91, a nozzle 92 and a heat-conducting frame 93. Two mounting frames 91 are installed on the top of the extrusion frame 2 by rivets. The upper parts of the two mounting frames 91 are both provided with nozzles 92. The outer wall of the sliding tube 75 is fixedly connected with a heat-conducting frame 93. The heat-conducting frame 93 is used to absorb the heat in the heat-conducting silicone in the extrusion tube 76. The heat-conducting frame 93 is located below the two nozzles 92.

[0036] During the process of extruding the thermally conductive silicone, the thermally conductive frame 93 absorbs the heat in the thermally conductive silicone in the extruded tube 76. Cold water is sprayed on the thermally conductive frame 93 through the nozzle 92 to cool the thermally conductive frame 93, thereby cooling the thermally conductive silicone in the extruded tube 76 more quickly and reducing the risk of deformation of the extruded thermally conductive silicone.

[0037] Embodiment 4: Based on the embodiment 3, Figure 7-Figure 9 As shown, it also includes a knocking component, which is arranged on the rotating rod 71 and connected to the limit block 73. The knocking component is used to knock on the surface of the sliding tube 75 so that the thermal conductive silicone is not easily adhered to the inner wall of the extrusion tube 76. The knocking component includes a pressing plate 101, a pressing frame 102 and a weight 103. The pressing plate 101 is connected to the rotating rod 71 through a flat key. The edge of the pressing plate 101 is provided with a plurality of protrusions. The pressing frame 102 is rotatably connected to the limit block 73. The pressing plate 101 is in contact with one end of the pressing frame 102, and the other end of the pressing frame 102 is fixedly connected to the weight 103, and the weight 103 is located above the sliding tube 75.

[0038] When the rotating rod 71 rotates, it will drive the pressing plate 101 to rotate, and the pressing plate 101 will intermittently squeeze the pressing frame 102, so that the upper end of the pressing frame 102 moves downward, and the lower end of the pressing frame 102 moves upward, thereby driving the weight block 103 to move upward. When the pressing plate 101 no longer squeezes the pressing frame 102, the pressing frame 102 is reset under the action of gravity, and the pressing frame 102 drives the weight block 103 to move downward, so that the weight block 103 knocks on the surface of the sliding tube 75, causing the sliding tube 75 and the squeezing tube 76 to vibrate, further making it difficult for the thermal conductive silicone to adhere to the inner wall of the squeezing tube 76.

[0039] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
