DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0021] In the actual operation of the present invention, after impurities are removed from the rubber particles, they are melted into a whole through hot melting, and then the melted rubber block is placed inside the pressing groove 6. By starting the cylinder 12, the telescopic end of the cylinder 12 drives the lower pressing plate 16 to press down, and the rubber material inside the pressing groove 6 is pressed to complete the molding process and form the required shape.
[0022] The rubber in the utility model is refractory silicone rubber, and the refractory silicone rubber ceramicization requires drying, heating and sintering of the rubber parts; if the existing rubber parts are directly dried, heated and sintered, they contain more impurities, which reduces the performance of the rubber parts. Therefore, in the present invention, the rubber material is processed in advance to remove impurities in the rubber particles, and the rubber particles are pre-melted and formed. The rubber particles after pre-melting and forming themselves have already been in a preheating process, and then they are directly dried, heated and sintered to make refractory silicone rubber parts. The refractory silicone rubber parts produced in this way have relatively stable performance; in particular, they will not be prone to cracking, aging, impurities inside, and other problems.
[0023] An air pump 13 is fixed on the lower pressure plate 16, and the four corners of the bottom end of the lower pressure plate 16 are connected with plug posts 14. The bottom ends of the four plug posts 14 are provided with through holes, and one end of the through holes is connected to the air pump 13. Sockets 5 are provided at the four corners of the bottom end of the mold box 4, and a plurality of downwind vents 7 are provided at the bottom end of the pressing groove 6. The plurality of downwind vents 7 are distributed along the length direction of the mold box 4, and the plurality of downwind vents 7 are respectively connected with the plug posts 14. The plug posts 14 are inserted into the corresponding plug posts 5. The bottom end of the lower pressure plate 16 is provided with a plurality of upwind vents 15 along the length direction, and the plurality of upwind vents 15 are connected to the air pump 13.
[0024] A placement plate 3 is fixed to the top of the support seat 2, a side plate 8 is fixed to one side of the placement plate 3, a baffle is fixed to the other side of the placement plate 3, and the mold box 4 is clamped between the side plate 8 and the baffle. A threaded rod 9 is rotatably connected inside the side plate 8, one end of the threaded rod 9 extends out of the side plate 8, and an extrusion plate 10 is connected to the protruding end, and the extrusion plate 10 is attached to one side of the mold box 4.
[0025] In the actual operation of the utility model, the extrusion plate 10 can be driven to move by rotating the threaded rod 9, so that the extrusion plate 10 is close to or away from the mold box 4, which is convenient for fixing mold boxes 4 of different widths and has a wider range of applications.
[0026] In the actual operation of the utility model, when the lower pressing plate 16 is pressed downward, the plug 14 and the socket 5 are inserted in cooperation. By starting the air pump 13, the gas generated by the air pump 13 passes through the plug 14 and is finally discharged from the lower air outlet 7. When the lower pressing plate 16 retracts upward, the molded rubber loses the pressure at the top. The wind force generated by the lower air outlet 7 can lift the rubber material to prevent the rubber material from adhering to the inside of the mold box 4, so that the molded material can be easily taken out. At the same time, the wind force generated by the lower air outlet 7 can dissipate heat for the rubber material to prevent the rubber material from being overheated. In addition, part of the wind force generated by the air pump 13 can cool the upper surface of the rubber through the upper air outlet 15 below the lower pressing plate 16. The cooperation between the plug 14 and the socket 5 can play a positioning role.
[0027] When the lower pressing plate 16 is pressed downward, the wind generated by the air pump 13 can be discharged through the upper air port 15, which not only cools the upper surface of the rubber, but also applies a downward pressure to the rubber to prevent the rubber from moving during the pressing process. It should be noted that the squeezing force of the cylinder 12 is greater than the driving force of the wind.
[0028] The bottom of the extrusion plate 10 is provided with an embedded groove, in which a temperature sensor is arranged, and the temperature sensor is flush with the bottom of the embedded groove. During the extrusion process, the extrusion plate 10 can use the temperature sensor to sense the temperature of the rubber material in real time. When the temperature of the rubber material is high, the temperature sensor can transmit a signal to the controller, and the controller controls the air pump 13 to turn on.
[0029] The bottom end of the sliding block 11 is connected with a transverse plate 18, and sliding rods 19 are fixed on both sides of the top of the lower pressing plate 16. Sliding openings for the sliding rods 19 to slide through are provided on both sides of the top of the transverse plate 18 to improve the stability of the downward movement.
[0030] Working principle: In the actual operation of the utility model, the rubber particles are melted into a whole by hot melting, and then the melted rubber block is placed inside the pressing groove 6. By starting the cylinder 12, the telescopic end of the cylinder 12 drives the lower pressing plate 16 to press down, and the rubber material inside the pressing groove 6 is pressed to complete the molding process and form the required shape.
[0031] In the actual operation of the utility model, when the lower pressing plate 16 is pressed downward, the plug 14 and the socket 5 are inserted in cooperation. By starting the air pump 13, the gas generated by the air pump 13 passes through the plug 14 and is finally discharged from the lower air outlet 7. When the lower pressing plate 16 retracts upward, the molded rubber loses the pressure at the top. The wind force generated by the lower air outlet 7 can lift the rubber material to prevent the rubber material from adhering to the inside of the mold box 4, so that the molded material can be easily taken out. At the same time, the wind force generated by the lower air outlet 7 can dissipate heat for the rubber material to prevent the rubber material from being overheated. In addition, part of the wind force generated by the air pump 13 can cool the upper surface of the rubber through the upper air outlet 15 below the lower pressing plate 16. The cooperation between the plug 14 and the socket 5 can play a positioning role.
[0032] When the lower pressing plate 16 is pressed downward, the wind generated by the air pump 13 can be discharged through the upper air port 15, which not only cools the upper surface of the rubber, but also applies a downward pressure to the rubber to prevent the rubber from moving during the pressing process. It should be noted that the squeezing force of the cylinder 12 is greater than the driving force of the wind.
