[0031] In this embodiment: the silicone is placed between the mounting frames 2, and the mold frame 5 is driven to move by the hydraulic cylinder 3 to extrude and shape the silicone. The existing device {publication (announcement) number}: CN202020149412.2 discloses an extrusion mold for a silicone sealing strip. This application further improves this existing subject. For details, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "although the silicone can be extruded and fixed by cylinder extension, people need to debug and calibrate the position of the silicone before fixing it. The calibration method is easy to have errors because it is observed by the human eye, which leads to errors in the placement of the silicone and affects the extrusion effect". In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a fixing component 6 is added to the application document.

[0032] It should be noted that the electrical equipment involved in this product is powered by an external power supply.

[0033] The extrusion die of the silicone sealing strip also includes a fixing component 6 installed on the mounting frame 2;

[0034] The fixing assembly 6 includes a shell 611 welded to the surface of the mounting frame 2 and a cylinder A61 fixedly arranged on the top of the shell 611, and a movable plate 62 is fixedly arranged at one end of the cylinder A61 inserted into the shell 611, and a symmetrically arranged extrusion block A63 is welded to the side of the movable plate 62 away from the cylinder A61, and an extrusion block B64 is abutted and connected to the side of the extrusion block A63 away from the movable plate 62, and a clamping plate 66 is welded to the side of the extrusion block B64 away from the extrusion block A63, and the clamping plate 66 is slidably connected in a through groove opened on the surface of the mounting frame 2.

[0035] In this embodiment: the silicone is placed between the clamping plates 66. When in operation, the cylinder A61 pushes the movable plate 62 to drive the extrusion block A63 to move. At the same time, the extrusion block A63 drives the roller 65 to move relative to the extrusion block B64, thereby achieving the center clamping of the silicone, avoiding installation deviation, reducing fixing errors, and assisting people in extrusion and shaping.

[0036] In an optional embodiment, the extrusion block A63 and the extrusion block B64 are trapezoidal structures extending outward, and the step surfaces of the extrusion block A63 and the extrusion block B64 conflict with each other.

[0037] In this embodiment: This design is used to provide an operating guide for the extrusion block B64, so that the extrusion block B64 can move vertically along the extrusion block A63 when subjected to force.

[0038] In an optional embodiment, sliding grooves are opened at positions corresponding to the clamping plate 66 on both sides of the inner wall of the through groove of the mounting frame 2, and a sliding rod 67 is welded in the sliding groove. A sliding sleeve 68 is provided on the surface of the sliding rod 67. The sliding sleeve 68 extends out of one side of the mounting frame 2 and is fixedly connected to the clamping plate 66. A spring A69 is wound on the surface of the sliding rod 67 on one side of the sliding sleeve 68, and the two ends of the spring A69 are respectively fixedly connected to the sliding sleeve 68 and the mounting frame 2.

[0039] In this embodiment: when the cylinder A61 is reset, it can drive the extrusion block A63 to move upward and reset. At this time, the spring A69 is forced to rebound and push the sliding sleeve 68 to drive the clamping plate 66 to reset and move, thereby separating from the silicone, making it convenient for people to remove the silicone.

[0040] In an optional embodiment, the clamping plate 66 is an inverted L-shaped structure, and a plurality of rollers 65 equidistantly distributed horizontally are rotatably connected within the L-plane of the clamping plate 66 .

[0044] In this embodiment, when the cylinder B72 is in operation, the slide seat 73 is used to push the hinge rod 74 to move, so that the hinge rod 74 pushes the mold shell 75 to flip downward along the mold frame 5, making it convenient for people to take out the silica gel and assisting people in demoulding operations.

[0045] In an optional embodiment, rectangular limit blocks are welded at positions on both sides of the inner wall of the mold frame 5 corresponding to the mold shell 75, and the surface of the mold shell 75 is in contact with the limit blocks.

When the mold shell 75 is flipped over, since the silicone is at the bottom of the inner wall of the mold shell 75, people only need to insert their hands into the mold shell 75 to push the silicone out, thereby assisting people in the demolding operation.

[0049] The working principle and use process of the utility model are as follows: the silicone is placed between the clamping plates 66, and the cylinder A61 pushes the movable plate 62 to drive the extrusion block A63 to move during operation. At the same time, the extrusion block A63 drives the roller 65 to move relative to the extrusion block B64 to achieve the centering clamping of the silicone, avoid installation deviation, and reduce the fixing error. When the hydraulic cylinder 3 drives the mold frame 5 to move downward by telescoping to perform the extrusion operation, the hydraulic cylinder 3 can push the push plate 71 to move into the mold shell 75 to extrude the silicone, and the hydraulic cylinder 3 can push the push plate 71 to move into the mold shell 75 to extrude the silicone. 3 shrinks and resets, and the spring B78 rebounds under the force to push the mold frame 5 downward, so that the push plate 71 is separated from the silicone. When the mold shell 75 is turned over, since the silicone is at the bottom of the inner wall of the mold shell 75, people only need to insert their hands into the mold shell 75 to push the silicone out, which assists people in demoulding. When the cylinder A61 is reset, it can drive the extrusion block A63 to move upward and reset. At this time, the spring A69 rebounds under the force to push the sliding sleeve 68 to drive the clamping plate 66 to reset and move, thereby separating from the silicone, making it convenient for people to remove the silicone.
