This type of plastic mold structure, with its excessive number of nuts and bolts, makes the mold structure overly complex. This not only affects the internal molding structure but also makes mold assembly and disassembly extremely difficult and cumbersome, resulting in reduced production efficiency. Utility Model Content

[0025] Reference Figures 1-5 This utility model provides an embodiment of a precision temperature-controlled plastic mold structure, including a concave mold assembly base plate 4. A concave mold assembly clamping plate 2 is slidably connected to the upper surface of the concave mold assembly base plate 4. The concave mold assembly clamping plate 2 can limit the displacement of the temperature control baffle 1 and maintain stability. A pressing and gripping mechanism is provided at the bottom of the concave mold assembly base plate 4. The pressing and gripping mechanism includes a support column 21 and four mold gripping push plates 6. The outer surfaces of the four mold gripping push plates 6 are slidably connected to the inner wall of the concave mold assembly base plate 4. The four mold gripping push plates 6 can move to limit the position of the temperature control baffle 1. The top of the support column 21 is fixedly connected to the bottom of the die assembly base plate 4. The upper and lower sides of the outer wall of the support column 21 are rotatably connected to the linkage plate 17. One of the linkage plates 17 is rotatably connected to the first rotating shaft rod 20 at both ends, so as to realize the movement of the die gripping push plate 6 on the opposite side. The other linkage plate 17 is rotatably connected to the second rotating shaft rod 22 at both ends. The ends of the two first rotating shaft rods 20 are rotatably connected to the bottom of the die gripping push plate 6, and the two second rotating shaft rods 22 are rotatably connected to the bottom of the die gripping push plate 6, so as to realize the movement and fixation of the die gripping push plate on the opposite side, thereby fixing the die assembly.
[0026] Specifically, through the cooperation of the above structures, during use, the hydraulic rod 10 fixed to the rear support plate 9 and the front support plate 16 at the top of the die assembly plate 2 8 rotates the hydraulic rod 14 connected to the end to the top of the die assembly, so that the pressure plate 15 at the output end of the hydraulic rod presses the die assembly. This achieves a reduction in the complex fixing methods of the socket, plug, and nuts and bolts, reduces the conversion time and improves practicality. Through the linkage mechanism at the bottom of the die assembly plate 4, the die gripping push plate 6 on the opposite side can simultaneously push the temperature control baffle 1 to clamp the middle die assembly, so that various die assemblies can be fixed without being restricted by nuts and bolts. This achieves the effect of assembling various die assemblies, simplifying the complicated assembly of nuts and bolts, and improving work efficiency.
[0027] Reference Figures 1-5 Hydraulic rods 18 and 19 are fixedly connected to the lower surface of the die assembly plate 12. The output end of hydraulic rod 18 is fixedly connected to the bottom of the die clamping push plate 6, and the output end of hydraulic rod 19 is fixedly connected to the bottom of the die clamping push plate 6. Hydraulic rods 18 and 19 provide power to the die clamping push plate 6 on opposite sides of the output end. A die assembly plate 28 is slidably connected to the top of the die assembly base plate 4. A rear support plate 9 and a front support plate 16 are fixedly connected to the upper surface of die assembly plate 28. Hydraulic rods 10 are rotatably connected to the inner wall of the rear support plate 9. The front support plate 16 and the rear support plate 9 provide fulcrums for hydraulic rods 10 to move in a directional manner. C-shaped support rods 11 are rotatably connected to the outer wall of the front support plate 16. The ends of the C-shaped support rods 11 are rotatably connected to the output ends of hydraulic rods 10. The hydraulic rod 10 is movable at one end. The inner walls of the two C-shaped support rods 11 are rotatably connected to rotating rods 12. The ends of the two rotating rods 12 are rotatably connected to main rods 13. The end of the main rod 13 is fixedly connected to hydraulic rod 14, so that the kinetic energy output by hydraulic rod 10 is transferred to the main rod 13 to achieve the purpose of moving the main rod 13. The output end of hydraulic rod 14 is fixedly connected to pressure plate 15. The top of the cavity mold assembly base plate 4 is fixedly connected to a glue-filling nozzle 7, which can inject glue into the interior. The end of the mold clamping push plate 6 is fixedly connected to a temperature control baffle 1. The outer wall of the temperature control baffle 1 is equipped with a pressure-temperature gauge 5. The data provided by the pressure-temperature gauge 5 can be used to understand the internal temperature and pressure. The bottom of the cavity mold assembly base plate 4 is fixedly connected to a base 3 to achieve the stability of the entire operating table.
[0028] Specifically, through the cooperation of the above structures, during use, the temperature control baffle 1 and the die combination clamping plate 2 8 can release the die assembly through the die clamping push plate 6 to achieve rapid heat dissipation and demolding of the mold. The temperature control baffle 1 can heat the mold and conduct heat dissipation. One side of the temperature control baffle 1 is equipped with a pressure thermometer 5, which can detect temperature and pressure, and provide accurate temperature control for glue injection and cooling demolding. By reducing the modular components of nuts and bolts, it can be quickly disassembled to achieve the effect of rapid cooling and demolding.
[0029] Working principle: When needed, the die assembly is placed in the middle. The heights of die assembly plate 2 and die assembly plate 1 are adjusted. Die assembly plate 2 is inserted and stacked, higher than the die assembly. Die assembly plate 1 slides in and stacks, its height level with die assembly plate 2. Then, the two hydraulic rods 10 at the top of die assembly plate 2 extend and are fixed by the rear support plate 9 and the front support plate 16, allowing kinetic energy to be transferred to the main rod 13 through the rotating rod 12. The main rod 13 rotates downward, which drives the hydraulic rod 2 14 at the end of the main rod 13 to rotate downward. The output end of hydraulic rod 2 14 has a pressure plate 15, which can be adjusted to press the die assembly. The bottom of the die assembly base plate 4 has a support column 21, and the outer surface of the support column 21 is fitted with two linkage plates 17, each... The linkage plate 17 is connected to two opposing rotating shafts 20 and 22. The output ends of hydraulic rods 18 and 19 are each connected to a mold clamping push plate 6. When the output ends of hydraulic rods 18 and 19 retract, their respective mold clamping push plates 6 are linked to their opposing mold clamping push plates 6 via rotating shafts 20 and 22, respectively, so that the opposing mold clamping push plates 6 can retract and extend simultaneously. The mold clamping push plate 6 is linked with the temperature control baffle 1. The temperature control baffle 1 can be inserted and stacked to be higher than the die assembly so as to clamp the internal die assembly and heat the die assembly or improve the heat dissipation efficiency of the die assembly. The top of the die assembly has a glue injection nozzle 7 for easy glue injection. One side of the temperature control baffle 1 has a pressure-temperature gauge 5 to check the internal glue injection temperature and pressure.
