When the mold, that is, the die slot block, is installed through the connected mounting strips, the hydraulic cylinder applies upward pressure to drive the lower pedestal to slide upward along the vertical guide rod, and the upward movement of the lower pedestal drives the connected die slot block and the heating end shell upward together, and the granular material is input into the hopper through the feed pipe, and the material in the hopper melts under the action of the heating element in the heating end shell, and as the feed pipe moves upward, the feed pipe approaches The material pressing cylinder, supported by the pressure rod and the shrink tube, pushes the molten material in the hopper into the interior of the die slot block through the extrusion tube and the connecting tube, and then enters the forming slot through the extrusion slot on the die slot block. When the upper part of the limiting pressure plate is pressurized, the limiting pressure plate is pressurized to slide along the upper part of the die slot block and squeeze the return spring on the spring connecting rod. Then the limiting pressure plate moving downward blocks the extrusion slot, preventing the die slot block from continuing to discharge material through the extrusion slot. The extrusion slot is squeezed and closed by the auxiliary mechanism structure during the process of passing through the limiting pressure plate and following the die slot block, so as to prevent the extrusion slot from continuously discharging material and causing material overflow. At the same time, when the extrusion slot is closed by the limiting pressure plate, the upper pedestal and the lower pedestal continue to approach each other, so that the shrink tube connected to the fixed tube seat is continuously squeezed by the pressure rod to shrink the elastic spring, and the gap generated by the melting in the hopper is extruded and discharged from the extrusion slot along the extrusion tube and the connecting tube.

[0011] According to the above technical solution, the auxiliary mechanism includes an oil tank, the rear end of the oil tank is fixedly connected with a one-way inlet pipe, the outer surface of the shrink tube is fixedly connected with a one-way outlet pipe, the outer side of the bottom end of the shrink tube is fixedly connected with an air connecting pipe, the bottom surface of the upper pedestal is installed with an upper pressure module, the inner bottom end of the upper pressure module is fixedly connected with a pressure block, a lifting plate is arranged above the pressure block, the side surface of the lifting plate is slidably connected with a deflection rod, the side surface of the deflection rod is hingedly connected with a hinge seat, the bottom end of the deflection rod is slidably connected with a force-bearing pressure rod, and the bottom surface of the upper pressure module is fixedly connected with several tapered hole rods.

[0012] The cam is connected to the upper and lower guide rods, and the two ends of the cam are ... When the lever is pushed down and the lower seat moves up and down, the wear and tear caused by the sliding is reduced, and the smoothness of the upper and lower movements of the lower seat is improved. At the same time, when the pressure rod is reset with the lower seat downward, the piston connected to the pressure rod slides along the contraction tube, allowing the pressure spring in the contraction tube to be reset and the air pressure in the contraction tube to be reduced, so that the liquid in the oil tank enters the contraction tube in one direction along the one-way inlet pipe to balance the pressure, and the space in the contraction tube below is squeezed by the piston to discharge the air from the air connecting pipe into the pressure block. At this time, the gas in the pressure block is blown out through the small hole at the bottom, and the attachments blocking the hole are blown away by the blown air. When the upper pressure module contacts the die groove block, the die groove block squeezes the force-bearing pressure rod to push the deflection rod to flip around the hinge seat, so that the deflection rod presses the lifting plate downward and squeezes the tension spring, and allows the tapered hole rod connected to the force-bearing pressure rod to block the small hole at the bottom of the pressure block and apply downward pressure.

[0013] A production process of a brake pad hot pressing molding device based on carbon fiber reinforced resin, comprising: S1: Before hot pressing the brake pad, the corresponding mold needs to be installed on the top of the mounting plate, so that the mounting strip connected to the bottom of the mold is aligned with the slide groove and put in. The mounting strip will pass through the recessed part of the positioning lever until it touches the other end of the positioning lever. When the mounting strip continues to push and squeeze the positioning lever, the positioning lever will flip around the positioning axis as a node. At this time, the recessed part of the positioning lever will penetrate into the inner side of the correction groove opened on the side of the mounting strip. With the continuous pushing of the mounting strip, the positioning levers on both sides flip around the positioning axis and squeeze the convex rod of the stretching rod, so that the stretching rod pushes the inclined groove connecting piece through the end to bear force, so that the inclined groove connecting piece is forced to push the connected spring block slider to slide along the slide guide strip. When the limiting angle groove on the side of the mounting strip is aligned with the limiting spring block, the spring sheet on the limiting spring block releases the elastic force and fits with the limiting angle groove, thereby positioning the mounting strip, and then the stretching rod can be fixed by screws, and the limiting angle groove on the mounting strip is used to structurally cooperate with the positioning lever and the limiting spring block; S2: When replacing, pull the stretching rod to make the stretching rod slide along the connected positioning shaft and drive the oblique groove connecting pieces on both sides to approach each other. The movement of the oblique groove connecting piece drives the connected spring block slider to slide along the slider guide bar, so that the spring block slider drives the limiting spring block away from the limiting angle groove on the side of the positioning lever. At the same time, the convex rod on the side of the stretching rod pushes the contacting positioning lever to reset. After the positioning lever flips, it pushes the correction groove on the installation bar to slide along the slide groove. When the correction groove moves with the installation bar, the groove on the positioning lever resets away from the correction groove. Then, slide the template on the installation bar along the slide groove to remove it. S3: After the mold, i.e., the die slot block, is installed through the connected mounting strips, the hydraulic cylinder applies pressure upward to drive the lower pedestal to slide upward along the vertical guide rod, and the lower pedestal moves upward to drive the connected die slot block and the heating end shell upward, so that the granular material is input into the hopper through the feeding pipe, and the material in the hopper is melted under the action of the heating element in the heating end shell. As the feeding pipe moves upward, the feeding pipe approaches the pressing cylinder, and the pressing cylinder, supported by the pressure rod and the shrink tube, passes the molten material in the hopper through the extrusion pipe and the connecting pipe into the die slot block, and then enters the shaping groove through the extrusion groove on the die slot block. When the upper part of the limiting pressure plate is pressurized, the limiting pressure plate is pressed to slide along the upper part of the die slot block and squeeze the return spring on the spring connecting rod, and then the limiting pressure plate moving downward blocks the extrusion groove, preventing the die slot block from continuing to discharge material through the extrusion groove, and the extrusion groove is closed by the extrusion control of the auxiliary mechanism structure during the process of passing through the limiting pressure plate and following the die slot block; S4: After the extrusion trough is closed by the limiting pressure plate, the upper pedestal and the lower pedestal continue to approach each other, so that the shrink tube connected to the fixed tube seat is continuously squeezed by the pressure rod to shrink the elastic spring, and the gap generated by the melt in the hopper is extruded through the extrusion tube and the connecting tube to be discharged from the extrusion trough. When the pressing barrel contacts the bottom of the hopper, the pressing barrel continues to move upward with the lower pedestal, and the pressure spring in the shrink tube is squeezed by the pressure rod connected to the pressing barrel to offset the vertical force, and as the lower pedestal moves upward, the die slot block is close to the upper pressure module to extrude the material; S5: When the lower pedestal is in the initial state before moving upward, the liquid in the oil tank enters the inside of the shrink tube through the one-way inlet pipe, and as the piston connected to the pressure rod moves upward, it squeezes the shrink tube, and moves the liquid in the shrink tube through the connected one-way outlet pipe to the gap between the upper pedestal and the vertical guide rod, allowing the liquid to slide downward along the vertical guide rod; S6: When the pressure rod moves downward with the lower pedestal to reset, the piston connected to the pressure rod slides along the shrink tube, so that the pressure spring in the shrink tube is reset and the air pressure in the shrink tube is reduced, so that the liquid in the oil tank enters the shrink tube in one direction along the one-way inlet pipe to balance the pressure, and the piston squeezes the space in the shrink tube below to discharge the air from the air pipe into the pressure block. At this time, the gas in the pressure block is blown out through the small hole at the bottom, and the attachments blocking the hole are blown away by the blown air; S7: When the upper pressure module contacts the die slot block, the die slot block squeezes the stress-bearing pressure rod to push the deflection rod to flip around the hinge seat, so that the deflection rod presses the lifting plate downward and squeezes the tension spring, and the tapered hole rod connected to the stress-bearing pressure rod blocks the small hole at the bottom of the pressure block, and the gas connected to the air pipe is discharged to prevent attachments from sticking to the bottom of the pressure block.

The limiting angle groove on the mounting bar is structurally matched with the positioning lever and the limiting spring block to fix the mold on the mounting bar through structural engagement or fit, thereby reducing the time consumed by screw installation and thus improving the efficiency of replacing the mold. At the same time, the limiting spring block and the positioning lever are pulled and reset by the structural stretching rod, so that different types of molds can be quickly replaced, which is convenient for disassembly and installation, and the structural versatility and adaptability are improved through structural assembly. The present invention is provided with a heating end shell, a feeding pipe, a hopper, an extrusion pipe, a connecting pipe, a die slot block, a spring connecting rod, a limiting pressure plate, an isolating ring, an electric heating wire, an extrusion slot, a shaping slot, a pressing barrel, and a pressure rod. The limiting pressure plate is squeezed by an auxiliary mechanism structure during the process of following the die slot block to control the closing of the extrusion slot, so as to prevent the extrusion slot from continuously discharging materials and causing the materials to overflow. At the same time, the pressure rod connected to the pressing barrel squeezes the pressure spring in the shrink tube to offset the vertical force, thereby reducing the bubbles between the materials and improving the quality of the hot-pressed formed products. In addition, the clamping rod connected to the rear end of the positioning turning rod is turned around the positioning axis to approach each other, so that the clamping rod presses and seals the connection between the extrusion pipe and the connecting pipe, thereby improving the sealing effect. The present invention is provided with an oil tank, a one-way outlet pipe, an air connecting pipe, a one-way inlet pipe, a hinge seat, a deflection rod, an upper pressure module, a pressure block, a lifting plate, a force-bearing pressure rod, and a tapered hole rod. Liquid moves to the gap between the upper pedestal and the vertical guide rod through the connected one-way outlet pipe, allowing the liquid to slide downward along the vertical guide rod until the lower pedestal moves up and down, thereby reducing the wear caused by sliding and improving the smoothness of the up and down movement of the lower pedestal. At the same time, the tapered hole rod connected to the force-bearing pressure rod blocks the small hole at the bottom of the pressure block, and the gas connected to the air connecting pipe is discharged to prevent attachments from sticking to the bottom of the pressure block and affecting the product molding effect.

When the lower table base 51 moves up and down, the wear generated during sliding can be reduced, and the smoothness of the up and down movement of the lower table base 51 can be improved. At the same time, when the pressing rod 614 moves downward and resets with the lower table base 51, the piston connected to the pressing rod 614 slides along the contraction pipe 615, so that the pressing spring in the contraction pipe 615 resets and the air pressure in the contraction pipe 615 decreases. Thus, the liquid in the oil tank 71 enters the contraction pipe 615 unidirectionally along the one-way inlet pipe 74 to balance the pressure, and the air in the lower contraction pipe 615 is discharged into the pressing block 78 through the air connecting pipe 73 by the extrusion of the piston. At this time, the gas in the pressing block 78 is blown out through the small holes at the bottom, and the attachments blocking the holes are blown off by the blown air. When the upper pressing module 77 contacts the mold groove block 66, the mold groove block 66 squeezes the force-receiving pressure rod 710 to push the deflection rod 76 to flip around the hinge seat 75, so that the deflection rod 76 presses the lifting plate 79 downward to move and squeeze the tension spring, and the tapered hole rods 711 connected to the force-receiving pressure rod 710 block the small holes at the bottom of the pressing block 78. The gas discharged through the air connecting pipe 73 avoids the attachments sticking to the bottom of the pressing block 78 and affecting the product forming effect.

[0021] Working principle: Before hot pressing the brake pad, the corresponding mold needs to be installed above the mounting plate 52, and the mounting strip 54 connected to the bottom of the mold is aligned with the slide groove 53 and inserted. The mounting strip 54 will pass through the recessed part of the positioning lever 55 until it contacts the other end of the positioning lever 55. When the mounting strip 54 continues to push and squeeze the positioning lever 55, the positioning lever 55 will flip around the positioning axis 513 as a node. At this time, the recessed part of the positioning lever 55 will penetrate into the inner side of the positioning groove 56 opened on the side of the mounting strip 54. As the mounting strip 54 continues to push, the positioning levers on both sides will be tilted. After the rod 55 is turned around the positioning shaft 513, it squeezes the convex rod of the stretching rod 512, so that the stretching rod 512 pushes the inclined slot connecting piece 511 through the end to be stressed, and the inclined slot connecting piece 511 is forced to push the connected elastic block slider 59 to slide along the slider guide bar 510. When the limiting angle groove 57 on the side of the installation bar 54 is aligned with the limiting elastic block 58, the spring sheet on the limiting elastic block 58 releases the elastic force and fits with the limiting angle groove 57, thereby positioning the installation bar 54, and then the stretching rod 512 can be fixed by screws, and the limiting angle groove 57 on the installation bar 54 is aligned with the positioning turning rod 55 and the limiting elastic block 58. The block 58 is structurally matched to fix the mold on the mounting bar 54 through structural engagement or fit, thereby reducing the time consumed by screw installation and improving the efficiency of replacing the mold. When disassembly is required, the stretching rod 512 is pulled to slide along the connected positioning shaft 513 and drive the inclined groove connecting pieces 511 on both sides to approach each other. The inclined groove connecting piece 511 moves to drive the connected spring block slider 59 to slide along the slider guide bar 510, so that the spring block slider 59 drives the limiting spring block 58 away from the limiting angle groove 57 on the side of the positioning flip rod 55. At the same time, by stretching The convex rod on the side of the rod 512 pushes the contacting positioning lever 55 to reset, and the positioning lever 55 is turned over to push the correction groove 56 on the installation bar 54 to slide along the slide groove 53. When the correction groove 56 moves with the installation bar 54, the groove on the positioning lever 55 is reset away from the correction groove 56. Then, the template on the installation bar 54 can be slid along the slide groove 53 for removal. The limit spring block 58 and the positioning lever 55 are pulled and reset by the structural stretching rod 512, so that different types of molds can be quickly replaced, which is convenient for disassembly and installation, and the structural versatility and adaptability are improved through structural assembly. When the mold, i.e., the die slot block 66, is installed through the connected mounting strips 54, the hydraulic cylinder 8 applies pressure upward to drive the lower pedestal 51 to slide upward along the vertical guide rod 4. The lower pedestal 51 moves upward to drive the connected die slot block 66 and the heating end shell 61 upward together, and the granular material is input into the hopper 63 through the feed pipe 62. The material in the hopper 63 is melted under the action of the heating element in the heating end shell 61. As the feed pipe 62 moves upward, the feed pipe 62 approaches the pressing barrel 613, and the pressing barrel 613 moves upward under the pressure of the pressure rod 614 and the contraction Under the support of the pipe 615, the molten material in the hopper 63 enters the interior of the die slot block 66 through the extrusion pipe 64 and the connecting pipe 65, and then enters the shaped groove 612 through the extrusion groove 611 on the die slot block 66. When the upper part of the limiting pressure plate 68 is pressurized, the limiting pressure plate 68 is pressed to slide along the upper part of the die slot block 66 and squeeze the return spring on the spring connecting rod 67. Then the limiting pressure plate 68 moves downward to block the extrusion groove 611, preventing the die slot block 66 from continuing to discharge the material through the extrusion groove 611. During the process of the slot block 66, the auxiliary mechanism 7 structure squeezes and controls the extrusion slot 611 to be closed, so as to prevent the extrusion slot 611 from continuously discharging materials and causing the materials to overflow. At the same time, after the extrusion slot 611 is closed by the limiting pressure plate 68, the upper pedestal 9 and the lower pedestal 51 continue to approach each other, so that the shrink tube 615 connected to the fixed tube seat 616 is continuously squeezed by the pressure rod 614 to shrink the elastic spring, and through the squeezing, the gap generated by the melting in the hopper 63 is squeezed and discharged from the extrusion slot 611 along the extrusion tube 64 and the connecting tube 65. When the pressing barrel 613 contacts the bottom of the hopper 63, the pressing barrel 613 continues to move upward along with the lower pedestal 51, and the pressure rod 614 connected to the pressing barrel 613 squeezes the pressure spring in the shrink tube 615 to offset the vertical force, thereby reducing the bubbles between the materials and improving the quality of the hot-pressed products. In addition, the clamping rod 514 connected to the rear end of the positioning turning rod 55 turns around the positioning shaft 513 and approaches each other, so that the clamping rod 514 presses and seals the connection between the extrusion tube 64 and the connecting tube 65, thereby improving the sealing effect. When the lower pedestal 51 is in an initial state where it has not yet moved upward, the liquid in the oil tank 71 enters the interior of the contraction tube 615 through the one-way inlet pipe 74. As the piston connected to the pressure rod 614 moves upward, the contraction tube 615 is squeezed, and the liquid in the contraction tube 615 is moved to the gap between the upper pedestal 9 and the vertical guide rod 4 through the connected one-way outlet pipe 72, allowing the liquid to slide downward along the vertical guide rod 4 until the lower pedestal 51 moves up and down, which can reduce the wear caused by sliding and improve the smoothness of the upper and lower movements of the lower pedestal 51. At the same time, when the pressure rod 614 moves downward and resets with the lower pedestal 51, the piston connected to the pressure rod 614 slides along the contraction tube 615, allowing the pressure spring in the contraction tube 615 to reset and reduce the air pressure in the contraction tube 615 , so that the liquid in the oil tank 71 enters the shrink tube 615 in one direction along the one-way inlet pipe 74 to balance the pressure, and the piston squeezes the space in the shrink tube 615 below to discharge the air from the connecting pipe 73 into the pressure block 78. At this time, the gas in the pressure block 78 is blown out through the small hole at the bottom, and the attachments blocking the hole are blown away by the blown air. When the upper pressure module 77 contacts the die groove block 66, the die groove block 66 squeezes the stressed pressure rod 710 to push the deflection rod 76 to flip around the hinge seat 75, so that the deflection rod 76 presses the lifting plate 79 downward and squeezes the tension spring, and the tapered hole rod 711 connected to the stressed pressure rod 710 blocks the small hole at the bottom of the pressure block 78, and the gas connected through the connecting pipe 73 is discharged to prevent attachments from sticking to the bottom of the pressure block 78 and affecting the product molding effect.

When the mounting strip 54 continues to push and squeeze the positioning lever 55, the positioning lever 55 will flip around the positioning axis 513 as a node. At this time, the recessed part of the positioning lever 55 will penetrate into the inner side of the positioning groove 56 opened on the side of the mounting strip 54. As the mounting strip 54 continues to push, the positioning levers 55 on both sides rotate around the positioning axis 513. After the shaft 513 is turned over, the protruding rod of the stretching rod 512 is squeezed, so that the stretching rod 512 pushes the inclined slot connecting piece 511 through the end to be stressed, and the inclined slot connecting piece 511 is forced to push the connected elastic block slider 59 to slide along the slider guide bar 510. When the limiting angle groove 57 on the side of the installation bar 54 is aligned with the limiting elastic block 58, the spring sheet on the limiting elastic block 58 releases the elastic force and fits with the limiting angle groove 57, so as to position the installation bar 54.

The lower pedestal 51 moves upward to drive the connected die slot block 66 and the heating end shell 61 upward together, and the granular material is input into the hopper 63 through the feed pipe 62. The material in the hopper 63 is melted under the action of the heating element in the heating end shell 61. As the feed pipe 62 moves upward, the feed pipe 62 approaches the pressing barrel 613. The pressing barrel 613, supported by the pressure rod 614 and the shrink tube 615, moves the hopper 63. 3, the molten material enters the die slot block 66 through the extrusion pipe 64 and the connecting pipe 65, and then enters the shaped groove 612 through the extrusion groove 611 on the die slot block 66. When the upper part of the limiting pressure plate 68 is pressed, the limiting pressure plate 68 is pressed to slide along the upper part of the die slot block 66 and squeeze the return spring on the spring connecting rod 67. Then the limiting pressure plate 68 moves downward to block the extrusion groove 611, preventing the die slot block 66 from continuing to discharge the material through the extrusion groove 611. The auxiliary mechanism 7 structure squeezes and controls the extrusion groove 611 to be closed during the process of passing through the limiting pressure plate 68 and the die slot block 66. S4: After the extrusion groove 611 is closed by the limiting pressure plate 68, the upper pedestal 9 and the lower pedestal 51 continue to approach each other, so that the shrink tube 615 connected to the fixed tube seat 616 is continuously squeezed by the pressure rod 614 to shrink the elastic spring, and the gap generated by the melt in the hopper 63 is extruded through the extrusion tube 64 and the connecting tube 65 to be discharged from the extrusion groove 611.

At this time, the gas in the pressure block (78) is blown out through the small hole at the bottom, and the attachments blocking the hole are blown away by the blown air; S7: When the upper pressure module (77) contacts the die groove block (66), the die groove block (66) squeezes the stress-bearing pressure rod (710) to push the deflection rod (76) to flip around the hinge seat (75), so that the deflection rod (76) presses the lifting plate (79) downward and squeezes the tension spring, and the tapered hole rod (711) connected to the stress-bearing pressure rod (710) blocks the small hole at the bottom of the pressure block (78), and the gas connected through the air pipe (73) is discharged to prevent attachments from sticking to the bottom of the pressure block (78).
