[0041] Working process: when the epoxy resin sheet is hot-pressed, the forming machine base 1 is used as the base of the epoxy resin sheet forming machine. First, prepare the materials, select the appropriate epoxy resin and curing agent, and then impregnate the reinforcing materials in the epoxy resin to ensure uniform distribution. Then dry the prepreg to partially cure it. According to the shape of the finished sheet, cut the prepreg and lay it on the base block 16 to ensure uniform distribution. The hot-pressing plate 17 is heated by the built-in heater, which simultaneously heats the mold box 15 to the curing temperature. At this time, the output end of the pressure covering assembly is pressed down, first pressing the mold box 15 between the two No. 3 slides 14. As the pressure covering assembly continues to press down, the hot-pressing plate 17 at the bottom of the No. 3 slide 14 applies pressure to the mold box 15 between the two No. 2 slides 13. The hot-pressing plate 17 at the bottom of the No. 2 slide 13 applies pressure to the mold box 15 between the two No. 1 slides 12. The hot-pressing plate 17 at the bottom of the No. 1 slide 12 applies pressure to the mold box 15 between the two base plates 11. All the No. 1 elastic members are squeezed and contracted under stress to ensure that the material is tightly attached to the mold. Maintain the temperature and pressure until the epoxy resin is completely cured. Then cool the mold box 15 to room temperature. The output end of the pressure covering assembly retracts, and all the No. 1 elastic members are reset in turn to lift up, causing the No. 1 slide 12, the No. 2 slide 13, and the No. 3 slide 14 to reset in turn. The hot-pressed epoxy resin sheet can be removed and taken out, achieving the function of one-time molding of multiple epoxy resin sheets, replacing the traditional single epoxy resin sheet molding method, and improving the efficiency of epoxy resin sheet hot-pressing production. When the epoxy resin sheet is hot-pressed, the output end of the pressure covering assembly is pressed down, and the No. 3 slide 14 slides down first, squeezing the No. 1 elastic member inside the No. 2 slide 13 to contract. The No. 2 slide 13 and the No. 1 slide 12 also slide down in turn to apply pressure. In the process of pressure application, the sleeves on the No. 3 slide 14, the No. 2 slide 13, and the No. 1 slide 12 slide on the outer wall of the support rod 2, maintaining the stability of the No. 1 slide 12, the No. 2 slide 13, and the No. 3 slide 14 when they slide down under pressure. When the epoxy resin sheet is hot-pressed, the top plate 3 is fixed on the four support rods 2 to support the hydraulic cylinder 31. The output end of the hydraulic cylinder 31 drives the sliding pressure plate 32 to slide on the outer wall of the four side slides 4. The hot-pressing plate 17 at the bottom of the sliding pressure plate 32 is first pressed on the mold box 15 between the two No. 3 slides 14. The hot-pressing plate 17 squeezes the material on the base block 16 to apply pressure. Then the hot-pressing plate 17 at the bottom of the mold box 15 between the two No. 3 slides 14 applies pressure to the mold box 15 between the two No. 2 slides 13. The hot-pressing plates 17 at the No. 2 slide 13 and the No. 1 slide 12 apply pressure in turn until the epoxy resin sheet is hot-pressed and cured. The output end of the hydraulic cylinder 31 resets the sliding pressure plate 32. The No. 1 slide 12, the No. 2 slide 13, and the No. 3 slide 14 are reset by the elastic force of the No. 1 elastic member, achieving the function of hot-pressing the epoxy resin sheet.When the epoxy sheet is hot pressed, the multiple molded epoxy sheets are placed on the multiple bottom blocks 16, the bottom of the connecting rod 41 is placed on the inner wall of the forming machine base 1, and the top end of the connecting rod 41 is limited to the inner wall of the top plate 3, so that the connecting rod 41 can rotate and slide up and down. After the output end of the hydraulic cylinder 31 resets, it continues to drive the sliding pressure plate 32 to slide up. The sliding pressure plate 32 can lift the rotating assembly to adjust the position of the short plate 42 on the outer wall of the connecting rod 41, so that the short plate 42 near the mold box 15 on the connecting rod 41 lifts the side slide plate 4 respectively, and the two side slide plates 4 synchronously drive a bottom block 16 to slide on the inner wall of the mold box 15. The molded epoxy sheet on the bottom block 16 is lifted to the upper surface of the mold box 15, which is convenient for taking the molded epoxy sheet; when the connecting rod 41 is controlled to rotate to adjust the position of the multiple short plates 42, if the output end of the hydraulic cylinder 31 drives the sliding pressure plate 32 to slide down, at this time the short rod 52 on the sliding pressure plate 32 slides into the limiting groove 51 on the inner wall of the connecting rod 41. The short rod 52 and the limiting groove 51 cooperate to make the multiple short plates 42 coincide with the multiple hole grooves 5, so that the sliding pressure plate 32 can freely drive the No. 3 slide plate 14, the No. 2 slide plate 13 and the No. 1 slide plate 12 to slide down and pressurize. If the output end of the hydraulic cylinder 31 resets and drives the sliding pressure plate 32 to slide up, at this time the short rod 52 on the sliding pressure plate 32 slides up at the arc in the limiting groove 51. The short rod 52 and the limiting groove 51 cooperate to make the multiple short plates 42 staggered with the multiple hole grooves 5, and the topmost short plate 42 is located on the upper surface of the sliding pressure plate 32, and the remaining short plates 42 are sequentially located on the bottom of the multiple side slide plates 4. The output end of the hydraulic cylinder 31 drives the sliding pressure plate 32 to slide up again, and the multiple short plates 42 can lift the epoxy sheet on the bottom block 16 between the two side slide plates 4 to the upper surface of the mold box 15, which is convenient for taking the molded epoxy sheet, and plays a role in controlling the rotation of the connecting rod 41 to adjust the position of the multiple short plates 42;

[0042] When the formed epoxy sheet is taken, the transmission assembly drives the plurality of push frames 61 to slide to the mold box 15, the push frames 61 slide on the inner wall of the fixed frame 6, and the plurality of push plates 62 respectively push the bottom block 16 which has been leveled with the upper surface of the mold box 15, so as to push the formed epoxy sheet on the bottom block 16 to the edge of the mold box 15 for discharging. In the process of pushing, the epoxy sheet can slide between the two guide plates 63, and when the push plate 62 is pushed close to the two guide plates 63, the arc surfaces of the two guide plates 63 can be extruded, so that the two guide plates 63 are pressed into the inner wall of the mold box 15, the second elastic member is contracted under stress, and the epoxy sheet is guided to discharge by the two guide plates 63, thereby playing a role of pushing and taking the formed epoxy sheet. The guide plates 63 can also be extruded and slide into the inner wall of the mold box 15 in the process of pressing; when the plurality of push frames 61 are pushed and slid, the electric sliding block 71 slides on the first sliding rail 7, the connecting frame 72 slides on the bottom inner wall of the second sliding rail 73 driven by the electric sliding block 71, the connecting frame 72 synchronously pushes the plurality of push frames 61 which penetrate through the outer wall to slide, so that the plurality of push plates 62 push the formed epoxy sheet to discharge, thereby playing a role of pushing the plurality of push frames 61;

[0043] When the formed epoxy sheet on the bottom block 16 is pushed and discharged, the upper surface of the bottom block 16 is easy to adhere to the adhered slag. The storage box 8 stores the release agent, the release agent flows to the sponge brush 82 through the flow channel 81, and after the sponge brush 82 absorbs the release agent, the formed epoxy sheet is pushed and displaced by the sliding of the push plate 62, and the sponge brush 82 follows to coat the release agent on the upper surface of the bottom block 16, thereby reducing the adhesion of the slag on the bottom block 16 and facilitating the cleaning of the adhered slag. When the adhered slag on the bottom block 16 is cleaned, the holes on the push plate 9 are first communicated with the flow channel 81, and the holes on the side plate 91 are staggered and blocked with the flow channel 81 at this time. Part of the release agent in the storage box 8 is temporarily stored in the flow channel 81, and as the push plate 62 approaches the epoxy sheet, the push plate 9 is attached to the epoxy sheet and pushed, and the spring 92 is extruded and contracted under stress. At this time, the holes on the push plate 9 are staggered and blocked with the flow channel 81, and the holes on the side plate 91 are communicated with the flow channel 81, and the temporarily stored release agent in the flow channel 81 falls to the sponge brush 82 and is absorbed for coating, thereby playing a role of controlling the flow of the release agent;

[0044] When the bottom block 16 is coated with release agent, the scraper 93 fixed behind the sponge brush 82 follows the adhered slag and scrapes the slag, which falls into the cavity formed by the outer wall of the scraper 93 and the inner wall of the push plate 62 for temporary storage. The filter screen 94 performs dry and wet separation on the release agent left on the slag. The filtered slag is temporarily stored on the filter screen 94, and the excess release agent is filtered below the filter screen 94 and can be discharged and cleaned by opening the valve 95, thereby improving the cleaning effect of the adhered slag and ensuring the quality of the formed epoxy resin sheet.
