Description

Technical Field

[0001] This utility model relates to the field of shoe insole processing technology, and in particular to a cold press for shoe insole processing. Background Technology

[0002] Insoles are widely used in the footwear industry, health care, and for special purposes. Their main functions include sweat protection, cold protection, height increase, shock absorption, support, correction of poor foot posture, improvement of gait, enhancement of balance and stability, measurement of steps, distance, and exercise time, massage, and acupressure stimulation. Processing insoles requires a cold press, a device that shapes insoles at room temperature. Pressurization is generally achieved through hydraulic transmission, but some cold presses use electromechanical presses. The essence of cold pressing is utilizing the plastic deformation properties of metal to continuously flatten the microscopic peaks on the workpiece surface.

[0003] To address this, Chinese patent application CN220499434U discloses a cold press for wood processing, comprising a cold press frame; a cold press body is fixedly installed on the inner top wall of the cold press frame; a connecting plate is fixedly installed on the output end of the cold press body; a cold press plate is fixedly installed on the bottom surface of the connecting plate; a fixed seat is fixedly connected to the back of the cold press frame; two cylinders are fixedly installed on the front of the fixed seat; a sliding plate is fixedly connected to the telescopic ends of the two cylinders; a cleaning plate is fixedly connected to the bottom surface of the sliding plate; a wood cold press table is fixedly connected to the upper surface of the cold press frame; the bottom surface of the cleaning plate contacts the upper surface of the wood cold press table; a guide hood is fixedly connected to the left side of the wood cold press table; and two support plates are fixedly connected to the bottom surface of the wood cold press table. This cold press for wood processing has a structure for cleaning wood chips, improving the cleaning speed of wood chips above the cold press table and facilitating further cold pressing processing.

[0004] While current cold presses for shoe insole processing can generally meet people's needs, some problems still exist, as detailed below:

[0005] 1. The problem of difficulty in changing and fixing the mold in cold press for shoe insole processing: Different types of molds are required when processing shoe insoles. If the mold is not fixed during cold pressing, it may shift during processing, affecting the quality of processing.

[0006] 2. The cold press used for shoe insole processing has difficulty ejecting the processed material from the mold. After the material is cold pressed, some material may remain inside the mold, making it difficult to discharge. Utility Model Content

[0007] The purpose of this invention is to provide a cold press for shoe insole processing, which solves the defects of existing cold presses for shoe insole processing, such as difficulty in changing and fixing the mold and difficulty in ejecting the processed material from the mold.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cold press for processing insoles, including a bottom plate;

[0009] A base is installed at the top of the base plate, a workbench is installed at the top of the base, a mold is installed at the top of the workbench, and a discharge structure is installed inside the mold.

[0010] A bracket is installed at the top of the workbench, a top plate is installed at the top of the bracket, and a hydraulic cylinder is installed at the top of the top plate.

[0011] A hydraulic rod is installed at the bottom of the hydraulic cylinder, and a pressure plate is installed at the bottom of the hydraulic rod. A limit structure is installed inside the worktable.

[0012] In use, during processing, the material is first placed on the mold, and then the hydraulic cylinder works to drive the hydraulic rod to extend and retract. The extension and retraction of the hydraulic rod can drive the pressure plate to rise and fall. The pressure plate can press against the top of the mold to perform cold pressing processing on the material on the mold. The guide block and the guide rod form a sliding structure. When the pressure plate rises and falls, the guide blocks on both sides of the pressure plate can slide along the guide rod. The guide rod and the guide block work together to guide the rise and fall of the pressure plate.

[0013] Furthermore, the limiting structure includes a limiting plate, a guide rod, a threaded rod, and a screwing block. The threaded rod is movably connected inside the worktable, and screwing blocks are installed on both sides of the threaded rod. The limiting plate is movably connected to the outer side of the threaded rod. Tightening the screwing block causes the threaded rod to rotate, which in turn moves the limiting plate in the opposite direction. The movement of the limiting plate can clamp the mold in the middle, and the locking block on the limiting plate can lock the mold in place to fix it.

[0014] Furthermore, guide rods penetrate both ends of the limiting plate, and the guide rods are symmetrically distributed about the central axis of the limiting plate. The guide rods penetrate the limiting plate and can guide the limiting plate.

[0015] Furthermore, the discharge structure includes a top block, a moving groove, and a spring. The moving groove is located inside the mold, and a spring is installed inside the moving groove. Due to the elasticity of the spring at the bottom of the top block, the top block will automatically spring up and eject the processed material from inside the mold.

[0016] Furthermore, a top block is mounted on the top of the spring, and the top blocks are symmetrically distributed about the central axis of the mold, and the spring is elastic.

[0017] Furthermore, guide structures are installed on both sides of the pressure plate. The guide structures include guide blocks, connecting rods, guide grooves, and guide wheels. The guide blocks are installed on both sides of the pressure plate, and guide grooves are provided inside the guide blocks. A connecting rod passes through the middle of the guide grooves. The connecting rod and the guide blocks cooperate to guide the pressure plate.

[0018] Furthermore, both sides of the connecting rod are provided with sliding grooves, and a guide wheel is provided inside the guide groove. The connecting rod and the guide wheel form a sliding structure, and the guide block can slide along the connecting rod.

[0019] The advantages of the cold press for shoe insole processing provided by this utility model are as follows: A mold is movably connected to the top of the worktable. The mold can be installed on the top of the worktable. After the mold is placed on the top of the worktable, the limiting plate and the threaded rod form a threaded connection. Since the threads on the threaded rod are symmetrically distributed about the central axis of the threaded rod, turning the screw block will cause the threaded rod to rotate, which will move the limiting plate in the opposite direction. The movement of the limiting plate can clamp the mold in the middle. The locking block on the limiting plate can lock the mold and fix it. When disassembly is required, turning the threaded rod will cause the limiting plate to no longer lock the mold, and the mold can be disassembled. The guide rod passes through the limiting plate and can guide the limiting plate, thereby achieving the purpose of facilitating mold replacement and fixation in the cold press for shoe insole processing.

[0020] By setting a sliding groove inside the mold, the top block and the sliding groove form a sliding structure. The top block can slide inside the sliding groove. When the material is cold-pressed, the pressure plate will press the material into the mold. At this time, the top block will also be pressed into the sliding groove. After processing is completed, due to the elasticity of the spring at the bottom of the top block, the top block will automatically spring up and push out the processed material inside the mold. This achieves the purpose of automatic material discharge for the cold press machine used for shoe insole processing. Attached Figure Description

[0030] See attached document Figure 2-3 As shown, the top block 601 and the moving groove 602 form a sliding structure. The top block 601 can slide inside the moving groove 602. When the material is cold-pressed, the pressure plate 10 will press the material into the mold 5. At this time, the top block 601 will also be pressed into the moving groove 602. After the processing is completed, due to the elasticity of the spring 603 at the bottom of the top block 601, the top block 601 will automatically spring up and push out the processed material inside the mold 5.

[0031] A bracket 7 is installed at the top of the workbench 1, a top plate 9 is installed at the top of the bracket 7, and a hydraulic cylinder 11 is installed at the top of the top plate 9.

[0032] A hydraulic rod 12 is installed at the bottom end of the hydraulic cylinder 11, and a pressure plate 10 is installed at the bottom end of the hydraulic rod 12. Guide structures 8 are installed on both sides of the pressure plate 10. The guide structure 8 includes a guide block 801, a connecting rod 802, a guide groove 803, and a guide wheel 804. The guide block 801 is installed on both sides of the pressure plate 10. The guide groove 803 is provided inside the guide block 801. The connecting rod 802 passes through the middle of the guide groove 803. Sliding grooves are provided on both sides of the connecting rod 802. The guide wheel 804 is provided inside the guide groove 803. The connecting rod 802 and the guide wheel 804 constitute a sliding structure.

[0033] See attached document Figure 1-2 and attached Figure 5 As shown, during processing, the material is placed on the mold 5, and then the hydraulic cylinder 11 works to drive the hydraulic rod 12 to extend and retract. The extension and retraction of the hydraulic rod 12 can drive the pressure plate 10 to rise and fall. The pressure plate 10 can press against the top of the mold 5 to perform cold pressing processing on the material on the mold 5. The guide block 801 and the connecting rod 802 form a sliding structure. When the pressure plate 10 rises and falls, the guide blocks 801 on both sides of the pressure plate 10 can slide along the connecting rod 802. The connecting rod 802 and the guide block 801 cooperate to guide the rise and fall of the pressure plate 10.

[0034] The workbench 1 is equipped with a limiting structure 4. The limiting structure 4 includes a limiting plate 401, a guide rod 402, a threaded rod 403, and a screw block 404. The threaded rod 403 is movably connected inside the workbench 1. Screw blocks 404 are installed on both sides of the threaded rod 403. The limiting plate 401 is movably connected to the outer side of the threaded rod 403. The guide rod 402 passes through both ends of the limiting plate 401. The guide rod 402 is symmetrically distributed about the central axis of the limiting plate 401.

[0035] See attached document Figure 1-2 and attached Figure 4 As shown, the mold 5 can be installed on the top of the workbench 1. After the mold 5 is placed on the top of the workbench 1, the limiting plate 401 and the threaded rod 403 form a threaded connection. Since the threads on the threaded rod 403 are symmetrically distributed about the central axis of the threaded rod 403, turning the screw block 404 will cause the threaded rod 403 to rotate, which will move the limiting plate 401 in the opposite direction. The movement of the limiting plate 401 can clamp the mold 5 in the middle. The locking block on the limiting plate 401 can lock the mold 5 and fix the mold 5. When disassembly is required, turning the threaded rod 403 will cause the limiting plate 401 to no longer lock the mold 5, and the mold 5 can be disassembled. The guide rod 402 passes through the limiting plate 401 and can guide the limiting plate 401.
