[0002] The hydraulic cylinder protective sleeve hot pressing molding device is a professional equipment for the efficient manufacture of hydraulic cylinder protective sleeves. The device heats the mold to the material molding temperature through a heating system, and applies high pressure through a hydraulic system to fully fill and shape the material in the mold. The device is equipped with precise temperature control, pressure regulation and automation modules, which can ensure stable molding quality and high production efficiency. It is suitable for mass production of materials such as rubber and polyurethane, and is an ideal choice for the manufacture of hydraulic cylinder protective parts.

[0003] Molds are crucial for the production of hydraulic cylinder protective sleeves, enabling the creation of sleeves of similar size and dimensions. However, since the internal cavity of most molds is fixed, only one type of hydraulic cylinder protective sleeve can be hot-pressed. Different molds are required for different hydraulic cylinder protective sleeves. Existing molds and mold bases are mostly fixed with screws and nuts, and the screws are quite long, making disassembly and installation inconvenient and time-consuming. Therefore, this invention proposes a hot-pressing molding device for hydraulic cylinder protective sleeves to solve the above problems. Utility Model Content

Driving cylinders are symmetrically hinged to both sides of the connecting plate. The output end of the driving cylinder is hinged to the top of the gripper.

[0008] A further improvement is that: the upper mold base has symmetrical grooves on both sides, the bottom end of the gripper engages with the inner side of the groove, and one side of the clamping plate is attached to one side of the lower mold base.

[0009] A further improvement is that a set of guide rods are symmetrically fixedly connected to both sides of the lower mold base, and a set of guide holes are symmetrically provided on both sides of the upper mold base, with the top of the guide rods inserted into the interior of the guide holes.

[0010] A further improvement is that: reference blocks are symmetrically fixedly connected to both sides of the worktable, and a cooling chamber is provided on the top of the worktable to fit the lower mold base, with a cooling mechanism inside the cooling chamber.

[0011] A further improvement is that the cooling mechanism includes an inlet pipe, a return pipe, and a coil. The coil is installed inside the cooling chamber. One end of the coil is connected to the inlet pipe, and the other end of the coil is connected to the return pipe. One end of the inlet pipe and the return pipe are respectively connected to the output end and the input end of the external cooling tower.

[0013] The beneficial effects of this utility model are as follows: The upper mold base is placed at the bottom of the connecting plate. The output end of the drive cylinder can drive the gripper to rotate around the rotation axis as the center. The output ends of the two drive cylinders move outward, driving the two grippers to rotate to the sides of the upper mold base and clamp them, so that the upper mold base and the output end of the lifting cylinder are connected as one unit. The lower mold base is placed on the top of the worktable. The limiting frame limits the lower mold base. The output ends of the two moving cylinders drive the two clamping plates to move to the sides of the lower mold base respectively. The two clamping plates clamp the sides of the lower mold base to fix the lower mold base to the top of the worktable. This solves the problem that in the prior art, molds and mold bases are mostly fixed by screws and nuts, and the screws are long, making the disassembly and installation process very inconvenient and wasting a lot of time.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a hot-press forming device for hydraulic cylinder protective sleeves, including a worktable 1, a support frame 2, and a limiting frame 3. The support frame 2 is fixedly connected to the top of the worktable 1, and the limiting frame 3 is fixedly connected to the outer side of the top of the worktable 1. A lower mold base 5 is provided on the top of the worktable 1, and a lifting cylinder 6 is fixedly installed on the top of the support frame 2. A clamping mechanism is provided at the output end of the lifting cylinder 6, and an upper mold base 4 is clamped at the bottom of the clamping mechanism. Fixing mechanisms are symmetrically provided on both sides of the limiting frame 3. Heating resistors are provided inside the upper mold base 4 and the lower mold base 5. The blank is placed between the upper mold base 4 and the lower mold base 5. The lower mold base 5 is fixed to the top of the worktable 1 by the fixing mechanism. The upper mold base 4 is installed at the output end of the lifting cylinder 6 by the clamping mechanism. The heating resistor can convert electrical energy into heat energy to heat the upper mold base 4 and the lower mold base 5. The output end of the lifting cylinder 6 can drive the upper mold base 4 to move downward. The upper mold base 4 and the lower mold base 5 close together to hot-press the blank, thereby forming the hydraulic cylinder protective sleeve.

[0021] The clamping mechanism includes a connecting plate 7, a rotating shaft 8, grippers 9, and a drive cylinder 10. The output end of the lifting cylinder 6 is fixedly connected to the connecting plate 7. Grippers 9 are symmetrically hinged to both sides of the connecting plate 7 via the rotating shaft 8. Drive cylinders 10 are symmetrically hinged to both sides of the connecting plate 7. The output end of the drive cylinder 10 is hinged to the top of the gripper 9. The upper mold base 4 has symmetrically provided grooves 15 on both sides. The bottom end of the gripper 9 is engaged with the inner side of the groove 15. When the upper mold base 4 is placed at the bottom of the connecting plate 7, the output end of the drive cylinder 10 can drive the gripper 9 to rotate around the rotating shaft 8 as the center. The output ends of the two drive cylinders 10 move outward, driving the two grippers 9 to rotate to both sides of the upper mold base 4 to clamp it, so that the upper mold base 4 is connected to the output end of the lifting cylinder 6 as one unit. When replacing, the output ends of the two drive cylinders 10 retract inward, driving the two grippers 9 to rotate to the outside of the upper mold base 4 to release it. At this time, a new upper mold base 4 can be installed.

[0022] The fixing mechanism includes a movable cylinder 11 and a clamping plate 12. Movable cylinders 11 are symmetrically fixedly installed on both sides of the limiting frame 3. The output end of the movable cylinder 11 is fixedly connected to the clamping plate 12. One side of the clamping plate 12 is attached to one side of the lower mold base 5. The lower mold base 5 is placed on the top of the workbench 1. The limiting frame 3 limits the lower mold base 5. The output ends of the two movable cylinders 11 drive the two clamping plates 12 to move to the two sides of the lower mold base 5 respectively. The two clamping plates 12 clamp the two sides of the lower mold base 5 to fix the lower mold base 5 on the top of the workbench 1. When replacing, the output end of the movable cylinder 11 can drive the clamping plate 12 away from the lower mold base 5. At this time, the lower mold base 5 can be removed from the top of the workbench 1 and replaced with a new lower mold base 5.

[0023] A set of guide rods 13 are symmetrically fixedly connected to both sides of the lower mold base 5, and a set of guide holes 14 are symmetrically provided on both sides of the upper mold base 4. The top end of the guide rod 13 is inserted into the interior of the guide hole 14. The guide rod 13 and the guide hole 14 cooperate to restrict the movement trajectory of the upper mold base 4. The upper mold base 4 can move up and down along the outer wall of the guide rod 13 to ensure the accuracy of the upper mold base 4 when pressing with the limiting frame 3.

[0024] The workbench 1 has reference blocks symmetrically fixedly connected to both sides. A cooling chamber, which fits against the lower mold base 5, is located on the top of the workbench 1. The cooling chamber contains a cooling mechanism, which includes an inlet pipe 16, a return pipe 17, and a coil 18. The coil 18 is installed inside the cooling chamber. One end of the coil 18 is connected to the inlet pipe 16, and the other end is connected to the return pipe 17. One end of the inlet pipe 16 and the return pipe 17 are respectively connected to the output and input ends of an external cooling tower. The external cooling tower will... Cold water is supplied into the coil 18 through the inlet pipe 16. The bottom of the lower mold base 5 is provided with a heat-conducting rod inserted into it. The bottom of the heat-conducting rod contacts the top of the coil 18. The cold water inside the coil 18 absorbs the heat energy inside the lower mold base 5 through the heat-conducting rod, and then is sent back to the external cooling tower through the return pipe 17. The cooling tower can continuously cool the water, and the cycle repeats to automatically cool the lower mold base 5. This alternating hot and cold water inside the lower mold base 5 reduces the stickiness of the oil cylinder protective sleeve to the lower mold base 5, making it easier to demold.

[0025] A set of bolts is symmetrically arranged in the middle of the connecting plate 7. The output end of the lifting cylinder 6 is fixedly connected to the assembly plate. The top of the bolt passes through the top of the assembly plate and is threaded with a nut.

[0026] The hot-press forming device for the hydraulic cylinder protective sleeve places the upper mold base 4 at the bottom of the connecting plate 7. The output end of the drive cylinder 10 can drive the gripper 9 to rotate around the rotating shaft 8 as the center. The output ends of the two drive cylinders 10 move outward, driving the two grippers 9 to rotate to both sides of the upper mold base 4 to clamp it, so that the upper mold base 4 is connected to the output end of the lifting cylinder 6 as one unit. When replacing, the output ends of the two drive cylinders 10 retract inward, driving the two grippers 9 to rotate to the outside of the upper mold base 4 to release it. At this time, a new upper mold base 4 can be installed. The lower mold base 5 is placed on the top of the worktable 1, and the limiting frame 3 is positioned to... The lower mold base 5 is limited, and the output ends of the two moving cylinders 11 drive the two clamping plates 12 to move to both sides of the lower mold base 5 respectively. The two clamping plates 12 clamp the two sides of the lower mold base 5 to fix the lower mold base 5 to the top of the worktable 1. When replacing, the output end of the moving cylinder 11 can drive the clamping plates 12 away from the lower mold base 5. At this time, the lower mold base 5 can be removed from the top of the worktable 1 and replaced with a new lower mold base 5. This solves the problem that in the existing technology, molds and mold bases are mostly fixed by screws and nuts, and the screws are long, making the disassembly and installation process very inconvenient and wasting a lot of time.
