Description

Technical Field

[0001] This utility model relates to the field of hydraulic press mold technology, specifically a hydraulic press mold quick positioning and clamping device. Background Technology

[0002] Hydraulic press mold positioning and clamping is crucial for ensuring machining accuracy, safe production, and mold lifespan. The core principle is to restrict mold displacement through precise positioning and then offset machining forces with reliable clamping. Positioning methods primarily include stop positioning, pin positioning, and guide rail positioning, each suitable for different scenarios such as small and medium-sized molds, high-precision machining, and large and heavy-duty molds. The core principle is to restrict the mold's degrees of freedom in the X, Y, and Z directions. Clamping commonly uses four types: hydraulic, mechanical, pneumatic, and automatic, adapting to the needs of medium and large-sized molds, small molds, light-duty molds, and mass production on assembly lines. The core principle is to provide sufficient and stable clamping force.

[0003] Regarding the above technical solutions, the existing clamping devices do not have a good quick positioning and clamping function, which will affect the clamping effect of the mold, and they do not have a good reinforcement function, which will affect the reliability of the clamping.

[0004] To address these issues, this invention provides a rapid positioning and clamping device for hydraulic press molds. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hydraulic press mold quick positioning and clamping device, which solves the problem that the existing clamping devices do not have a good quick positioning and clamping function, thus affecting the mold clamping effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic press mold quick positioning and clamping device, comprising a worktable, a positioning and clamping assembly fixedly installed on the top of the worktable, and a reinforcing assembly provided at the top and bottom of the worktable; the positioning and clamping assembly includes a positioning plate and a first slide groove, the positioning plate being fixedly installed on the top of the worktable, the first slide groove being formed on the top of the worktable, a clamping plate being slidably connected to the top of the first slide groove, a first U-shaped frame being fixedly installed on one side of the clamping plate, a connecting rod being hinged to the inner side wall of the first U-shaped frame, a threaded rod being connected to the top of the worktable via a bearing, a lifting plate being threadedly connected to the side wall of the threaded rod, a second U-shaped frame being fixedly installed on one side of the lifting plate, and the connecting rod being hinged to the second U-shaped frame.

[0007] Furthermore, the positioning and clamping assembly also includes a knob, which is fixedly connected to the top end of the threaded rod.

[0008] By adopting the above technical solution, the threaded rod can be easily adjusted by manually rotating the knob without the need for additional tools, thus improving operational flexibility.

[0009] Furthermore, the reinforcement component includes a circular block and a locking block. The circular block is fixedly connected to the side wall of the threaded rod, and the locking block is fixedly connected to the side wall of the circular block. A fixing plate is fixedly installed at the bottom of the workbench. A spring is fixedly connected to one side of the fixing plate. A moving plate is fixedly connected to one end of the spring. A locking rod is fixedly connected to one side of the moving plate. The locking rod and the locking block are engaged. A second sliding groove is provided at the top of the workbench, and the moving plate is slidably connected to the second sliding groove.

[0010] By adopting the above technical solution, the locking action between the clamping rod and the clamping block can lock the position of the threaded rod, prevent loosening during processing, and enhance clamping stability.

[0011] Furthermore, the reinforcement assembly also includes a slide rod and a pull ring. The slide rod is fixedly connected to one side of the movable plate and slidably connected to the fixed plate. The pull ring is fixedly connected to one end of the slide rod.

[0012] Using the above technical solution, pulling the pull ring will cause the locking rod to disengage from the locking block, quickly releasing the lock and facilitating mold disassembly.

[0013] Furthermore, the top of the worktable is connected to two rotating rollers via bearings, and the two rotating rollers are arranged opposite each other.

[0014] Using the above technical solution, the mold can slide along the rotating roller, reducing moving friction and easily pushing the mold to the positioning position.

[0015] Furthermore, a limiting block is fixedly connected to the side wall of the rotating roller, and the limiting block is circular in shape.

[0016] By adopting the above technical solution, the limiting block can prevent the mold from shifting laterally, avoid the mold from slipping off the roller, and ensure installation safety.

[0017] Furthermore, a mold body is provided on the top of the workbench, and the mold body is located in the middle of the positioning and clamping assembly.

[0018] By adopting the above technical solution, the positioning and clamping components can apply force evenly from both sides, ensuring the force balance of the mold and improving the positioning accuracy.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1 to 4 This application provides a hydraulic press mold quick positioning and clamping device, including a worktable 1. A positioning and clamping assembly 2 is fixedly installed on the top of the worktable 1, and a reinforcing assembly 4 is provided at the top and bottom of the worktable 1. The positioning and clamping assembly 2 includes a positioning plate 21 and a slide groove 22. The positioning plate 21 is fixedly installed on the top of the worktable 1, and the slide groove 22 is opened on the top of the worktable 1. A clamping plate 23 is slidably connected to the top of the slide groove 22, and a U-shaped frame 24 is fixedly installed on one side of the clamping plate 23. A connecting rod 25 is hinged to the inner wall of the frame 24. A threaded rod 26 is connected to the top of the worktable 1 via a bearing. A lifting plate 27 is threaded to the side wall of the threaded rod 26. A U-shaped frame 28 is fixedly installed on one side of the lifting plate 27. The connecting rod 25 is hinged to the U-shaped frame 28. The positioning and clamping assembly 2 also includes a knob 29, which is fixedly connected to the top of the threaded rod 26. A mold body 3 is provided on the top of the worktable 1, and the mold body 3 is located in the middle of the positioning and clamping assembly 2.

[0032] In this embodiment, the mold body 3 is first placed on the rotating roller 5 on the top of the workbench 1. The rotating roller 5 rotates through the bearing to reduce the friction of the mold movement, helping the operator to easily push the mold to the middle of the positioning and clamping assembly 2. At the same time, the circular limiting block 6 on the side wall of the rotating roller 5 can prevent the mold from shifting laterally and avoid the mold from slipping. After the mold is initially aligned, the knob 29 at the top of the threaded rod 26 in the positioning and clamping assembly 2 is rotated to drive the threaded rod 26 to rotate around the bearing on the top of the workbench 1. Since the threaded rod 26 is threadedly connected to the lifting plate 27, the rotation of the threaded rod will drive the lifting plate 27 to rise and fall in the vertical direction. The U-shaped frame 28 on one side of the lifting plate 27 moves accordingly, thereby pulling the connecting rod 25 that is hinged to it. The other end of the connecting rod 25 is hinged to the U-shaped frame 24 on the clamping plate 23. Under the traction of the connecting rod, the clamping plate 23 slides along the slide groove 22 on the top of the workbench 1, and finally clamps the mold body 3 from both sides, completing the rapid positioning and initial clamping of the mold.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the reinforcing component 4 includes a circular block 41 and a locking block 42. The circular block 41 is fixedly connected to the side wall of the threaded rod 26, and the locking block 42 is fixedly connected to the side wall of the circular block 41. A fixing plate 43 is fixedly installed at the bottom of the workbench 1. A spring 44 is fixedly connected to one side of the fixing plate 43. A movable plate 45 is fixedly connected to one end of the spring 44. A locking rod 46 is fixedly connected to one side of the movable plate 45. The locking rod 46 and the locking block 42 are engaged. The top of the worktable 1 is provided with a second slide groove 47, and the movable plate 45 is slidably connected to the second slide groove 47. The reinforcing component 4 also includes a slide rod 48 and a pull ring 49. The slide rod 48 is fixedly connected to one side of the movable plate 45 and is slidably connected to the fixed plate 43. The pull ring 49 is fixedly connected to one end of the slide rod 48. The top of the worktable 1 is connected to two rotating rollers 5 through bearings, and the two rotating rollers 5 are arranged opposite to each other. A limit block 6 is fixedly connected to the side wall of the rotating roller 5. The limit block 6 is circular in shape.

[0034] In this embodiment, the reinforcing component 4 simultaneously achieves the locking function. The circular block 41 fixed to the side wall of the threaded rod 26 rotates with the threaded rod. When the locking block 42 on the circular block 41 rotates to the position corresponding to the locking rod 46, the spring 44 on the bottom fixed plate 43 of the worktable 1 pushes the moving plate 45 due to elastic potential energy. The moving plate 45 slides along the second slide groove 47, causing the locking rod 46 to be tightly engaged with the locking block 42, thereby locking the position of the threaded rod 26 and preventing the threaded rod from loosening during processing, which would cause the mold to shift. This further enhances the clamping stability. When it is necessary to disassemble the mold, the operator pulls the pull ring 49 at one end of the slide rod 48. The slide rod 48 slides along the fixed plate 43 and causes the moving plate 45 to compress the spring 44. The locking rod 46 disengages from the locking block 42 along with the moving plate 45, releasing the lock on the threaded rod 26. Rotating the knob 29 in the opposite direction will reset the clamping plate 23. Then, the mold can be pushed along the rotating roller 5 to complete the disassembly. The whole process does not require complicated tools, taking into account both clamping reliability and ease of operation.

[0035] Working principle: First, place the mold body 3 on the rotating roller 5 on the top of the workbench 1. The rotating roller 5 rotates through the bearing to reduce the friction of the mold movement, helping the operator to easily push the mold to the middle of the positioning and clamping assembly 2. At the same time, the circular limit block 6 on the side wall of the rotating roller 5 can prevent the mold from shifting laterally and prevent the mold from slipping. After the mold is initially aligned, rotate the knob 29 at the top of the threaded rod 26 in the positioning and clamping assembly 2 to drive the threaded rod 26 to rotate around the bearing on the top of the workbench 1. Since the threaded rod 26 is threadedly connected to the lifting plate 27, the rotation of the threaded rod will drive the lifting plate 27 to rise and fall in the vertical direction. The U-shaped frame 28 on one side of the lifting plate 27 moves accordingly, which in turn pulls the connecting rod 25 that is hinged to it. The other end of the connecting rod 25 is hinged to the U-shaped frame 24 on the clamping plate 23. Under the traction of the connecting rod, the clamping plate 23 slides along the slide groove 22 on the top of the workbench 1, and finally clamps the mold body 3 from both sides, completing the rapid positioning and initial clamping of the mold.

[0036] The reinforcing component 4 synchronously achieves the locking function. The circular block 41 fixed to the side wall of the threaded rod 26 rotates with the threaded rod. When the locking block 42 on the circular block 41 rotates to the position corresponding to the locking rod 46, the spring 44 on the bottom fixed plate 43 of the worktable 1 pushes the moving plate 45 due to the elastic potential energy. The moving plate 45 slides along the slide groove 47, causing the locking rod 46 to be tightly engaged with the locking block 42, thereby locking the position of the threaded rod 26 and preventing the threaded rod from loosening during processing and causing the mold to shift, further enhancing the clamping stability. When it is necessary to disassemble the mold, the operator pulls the pull ring 49 at one end of the slide rod 48. The slide rod 48 slides along the fixed plate 43 and drives the moving plate 45 to compress the spring 44. The locking rod 46 disengages from the locking block 42 along with the moving plate 45, releasing the lock on the threaded rod 26. Rotating the knob 29 in the opposite direction will reset the clamping plate 23. Then, the mold can be pushed along the rotating roller 5 to complete the disassembly. The whole process does not require complicated tools, taking into account both clamping reliability and operation convenience.
