[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention discloses a hot-melt extrusion device for silicone plate processing, including an extruder main body 10. One end of the extruder main body 10 is connected to an extrusion head 20. One end of the extrusion head 20 is in contact with a silicone plate forming die head 30. Four inclined first guide rods 40 are welded on one side of the extruder main body 10. A U-shaped fastening slide 50 is slidably connected between the upper and lower first guide rods 40. Each first guide rod 40 is welded with a spring 60. The two ends of the spring 60 are respectively welded and connected to the U-shaped fastening slide 50 and the first guide rod 40. A pushing mechanism 70 is sleeved on the extrusion head 20.

[0021] The spring 60 plays an elastic pulling role. When not subjected to the thrust of the pushing mechanism 70, the spring 60 will pull the U-shaped fastening slide 50 at this time. The U-shaped fastening slide 50 slides along the inclined first guide rod 40. At this time, the distance between two adjacent U-shaped fastening slides 50 gradually increases, and it can be separated from the silicone plate forming die head 30, so that the silicone plate forming die head 30 loses its locking and is convenient to replace.

[0022] Specifically, the pushing mechanism 70 includes a mounting seat 71. An electric push rod 72 is fixedly installed on one side of the mounting seat 71. The output end of the other end of the electric push rod 72 is fixedly connected to a sliding sleeve 73. The sliding sleeve 73 is slidably sleeved on the extruder main body 10. Two push pieces 74 are welded at one end of the sliding sleeve 73. A mounting long plate 80 is fixedly installed at the bottom end of the mounting seat 71. A plurality of brackets 90 are fixedly connected to the top surface of the mounting long plate 80. The top surface of each bracket 90 is fixedly connected to the bottom end of the extruder main body 10. The push piece 74 is of an L-shaped structure, and the push piece 74 is in contact with one side surface of the U-shaped fastening slide 50.

[0023] In this implementation scheme, it plays a role in pushing the U-shaped fastening slide 50 to move. Since it is not fixedly connected to the U-shaped fastening slide, it will not interfere with the inclined sliding of the U-shaped fastening slide 50. By pushing the U-shaped fastening slide 50 to move, the locking of the silicone plate forming die head 30 can be achieved.

[0024] Specifically, the silicone plate forming die 30 includes a connecting seat 31, one end of the connecting seat 31 is integrally connected to the mold 32, the upper and lower ends of the connecting seat 31 are welded with convex seats 33, and one side of the two convex seats 33 is provided with a circular hole 34. One end of the extruder body 10 is fixedly connected to two second guide rods 100, and the two second guide rods 100 respectively pass through the two circular holes 34. Silicone plate forming dies 30 of different specifications only differ in the mold 32. The connecting seat 31 is attached to one side of the extruder head 20, and the connecting seat 31 has the same outer diameter as the extruder head 20 and is coaxial.

[0025] In this embodiment, the mold 32 can be used for the molding and extrusion of the silicone plate, and the circular hole 34 can be sleeved on the second guide rod 100, so as to realize the positioning and placement of the entire silicone plate molding die head 30. The protrusion 33 can be used in conjunction with the U-shaped fastening slide 50 to realize the fixed installation of the entire silicone plate molding die head 30. At the same time, silicone plate molding dies 30 of different specifications only have the mold 32 different, with strong uniformity, which is convenient for subsequent disassembly and assembly.

[0026] The working principle and use process of the utility model are as follows: the raw materials for forming the silicone plate are poured into the upper hopper of the extruder 10, and then the raw materials are heated by the internal components of the extruder 10 to melt into liquid and transported to the extruder head 20, and then transported to the silicone plate forming die 30 through 30 for molding, and finally, after subsequent cooling, cutting and other processes, a silicone plate can be obtained;

[0027] The disassembly and assembly steps of the silicone plate forming die 30 are as follows: start the electric push rod 72 to retract the output end, at this time the sliding sleeve 73 moves close to the mounting seat 71, and the two push pieces 74 move close to the mounting seat 71, and the U-shaped fastening slide 50 loses the push of the push piece 74. Under the elastic force of the spring 60, the U-shaped fastening slide 50 moves along the first guide rod 40 and away from the side of the extruder head 20. At this time, the distance between the two U-shaped fastening slides 50 slowly increases, and the convex seat 33 in the silicone plate forming die 30 loses the extrusion, and the U-shaped fastening slide 50 is staggered with the convex seat 33, and the entire silicone plate forming die 30 can be directly pulled out from the second guide rod 100, and the required silicone plate forming die 30 can be replaced, and the second guide rod 100 is made to pass through the circular hole 34, and the connecting seat 31 is fitted on the extruder head 20, and then the electric push rod 72 is started to extend the output end. At this time, the push piece 74 pushes the U-shaped fastening slide 50, and the distance between the two U-shaped fastening slides 50 slowly decreases. Finally, the U-shaped fastening slide 50 is tightly pressed against the convex seat 33, and the silicone plate forming die 30 can be fixedly installed.
