Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, and in particular to a precision machining mold. Background Technology
[0002] Precision machining molds are specialized process equipment used in the mechanical manufacturing field to achieve high-precision parts forming. They are widely used in industries with extremely high precision requirements, such as automobiles, aerospace, electronics, and medical devices. Their core function is to process raw materials such as metals, plastics, and ceramics into finished or semi-finished products with specific dimensions, shapes, and surface qualities through a pre-set cavity structure and positioning system.
[0003] Precision machining molds are made by using a pre-set, high-precision matched cavity and a molded part. Under the pressure, temperature or other external forces provided by mechanical equipment, the raw material (such as metal, plastic, etc.) undergoes plastic deformation, flow or solidification according to the shape and size of the cavity. At the same time, the positioning and guiding device ensures the accurate relative position of each component. Finally, the raw material is molded into a precision part that meets the design requirements. The molded part is then separated from the mold by auxiliary mechanisms (such as ejection and unloading devices).
[0004] In existing technologies, some precision machining molds have fixed-size positioning structures, which makes it impossible for the specifications and spacing of their positioning grooves and blocks to be adapted to the dimensions of different parts, thus affecting the efficiency of the machining mold. Therefore, a precision machining mold is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a precision machining mold, which aims to improve the problem that some precision machining molds in the prior art cannot flexibly adapt to the processing requirements of parts of different sizes and shapes during use, thus affecting the efficiency of the machining mold.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A precision machining mold includes multiple support columns, a worktable fixedly connected to the top of each support column, a support frame fixedly connected to the top of the worktable, a movable mechanism fixedly connected inside the support frame, a positioning mechanism fixedly connected inside the left end of the worktable, a fixing mechanism fixedly connected inside the movable mechanism, the movable mechanism including a cylinder, the cylinder being fixedly connected to the inside of the support frame, a fixing plate fixedly connected to the drive end of the cylinder, the positioning mechanism including a sliding plate, a drive assembly fixedly connected to the left end of the sliding plate, two rotating rods rotatably connected inside the sliding plate, each of the two rotating rods being rotatably connected to a rotating shaft, a rubber plate fixedly connected to the outside of the rotating shaft, two support shafts fixedly connected inside the support frame, and two slide rails provided at the top of the worktable. As a further description of the above technical solution: The fixing mechanism includes two fixing rings, which are externally fixedly connected to the inside of the fixing plate. A sliding shaft is slidably connected inside the fixing rings, and a sliding rod is slidably connected inside the sliding shaft. A limit ring is fixedly connected to the outside of the sliding shaft, and a spring is sleeved on the outside of the sliding shaft. A connecting shaft is fixedly connected to the bottom of the sliding rod, and limit shafts are fixedly connected to both ends of the connecting shaft. Rotating blocks are rotatably connected to the outside of the two limit shafts, and stamping dies are slidably attached to the outside of the two rotating blocks. As a further description of the above technical solution: The drive assembly includes a second cylinder, which is externally and fixedly connected to the inside of the left end of the worktable. The drive end of the second cylinder is fixedly connected to a drive shaft, and the right end of the drive shaft is fixedly connected to the left end of the sliding plate. As a further description of the above technical solution: The bottom of the sliding plate is slidably connected to the inside of the workbench, and the bottoms of the two rubber plates are slidably connected to the top of the workbench; As a further description of the above technical solution: The interiors of the two rotating shafts are slidably connected to the exteriors of the two supporting shafts, and the exteriors of the two rotating shafts are slidably connected to the interiors of the two slide rails. As a further description of the above technical solution: The tops of the two springs are respectively fixedly connected to the bottoms of the two limiting rings, and the bottoms of the two springs are respectively fixedly connected to the inside of the two fixing rings; As a further description of the above technical solution: The external part of the connecting shaft is slidably connected to the inside of the two rotating blocks, and the external part of the two rotating blocks is rotatably connected to the inside of the sliding shaft; As a further description of the above technical solution:
[0007] The sliding shaft is externally slidably connected to the inside of the stamping die, and the interior of each of the multiple rotating blocks is provided with a sliding groove.
[0008] This utility model has the following beneficial effects: 1. In this utility model, displacement is generated by starting the second cylinder to drive the drive shaft, which pushes the sliding plate to slide. The sliding plate drives the two rotating rods to rotate, which in turn drives the two rotating shafts to move. Under the limit of the support shaft and the slide rail, the two rotating shafts drive the two support shafts to move relative to each other. Even if there is a slight angular deviation in the placement of the part, the flexible fit of the elastic rubber plate 55 can achieve precise positioning to prevent the part from shifting during processing, thereby improving the flexibility and adaptability of mold processing and processing stability.
[0009] 2. In this utility model, pressing the sliding shaft causes it to rotate via the connecting shaft and the limiting shaft, thereby disengaging the stamping die. This reduces die replacement time and improves equipment maintenance efficiency. The sliding shaft drives the limiting ring to compress the spring, and the spring releases the elastic force, enabling the sliding shaft to achieve stable sliding positioning inside the stamping die. Combined with the embedding of the rotating block, this ensures a secure installation of the stamping die, thereby improving the efficiency of the stamping die and the continuity of processing.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Reference Figures 1 to 2 This utility model provides an embodiment of a precision machining mold, comprising multiple support columns 1, which are in contact with the ground to provide support and prevent the mold from shaking during processing, thereby improving the processing stability of the mold. A worktable 2 is fixedly connected to the top of the multiple support columns 1, providing a working platform. The multiple support columns 1 support the worktable 2, thereby improving its load-bearing capacity. A support frame 3, made of high-strength material, is fixedly connected to the top of the worktable 2, providing a support framework. The worktable 2 supports the support frame 3, thereby improving its support stability. A movable mechanism 4 is fixedly connected inside the support frame 3, providing support to prevent the movable mechanism 4 from shifting during operation, thereby improving the operational efficiency of the movable mechanism 4. A positioning mechanism 5 is fixedly connected inside the left end of the worktable 2, providing support for the positioning movement of the positioning mechanism 5, preventing the positioning mechanism 5 from deviating during operation, thereby improving the positioning accuracy of the positioning mechanism 5. The movable mechanism 4 is internally fixedly connected to a fixing mechanism 6, which provides fixation for the fixing mechanism 6 to prevent it from loosening during mold processing, thereby improving the stability of the fixing mechanism 6. The movable mechanism 4 includes a cylinder 41, which provides the drive source. The cylinder 41 is externally fixedly connected to the inside of the support frame 3, which provides fixation for the cylinder 41 to prevent it from shifting during operation, thereby improving the operational stability of the cylinder 41. A fixing plate 42 is fixedly connected to the drive end of the cylinder 41. By activating the cylinder 41, the fixing plate 42 is driven, causing it to move. The positioning mechanism 5 includes a sliding plate 52, the bottom of which is slidably connected to the inside of the worktable 2. The worktable 2 provides guidance for the sliding of the sliding plate 52, preventing it from shifting during sliding and thus improving its sliding stability. A drive assembly 51 is fixedly connected to the left end of the sliding plate 52. By activating the drive assembly 51, a sliding force is provided for the sliding plate 52 to slide inside the worktable 2. The drive assembly 51 includes a second cylinder 511, which is externally and fixedly connected to the interior of the left end of the worktable 2. The worktable 2 provides fixation for the second cylinder 511, preventing it from deviating during operation and thus improving its operational stability. A drive shaft 512 is fixedly connected to the drive end of the second cylinder 511. Activating the second cylinder 511 provides driving force to the drive shaft 512, causing it to displace. The right end of the drive shaft 512 is fixedly connected to the left end of the sliding plate 52. The displacement of the drive shaft 512 pushes the sliding plate 52 to slide within the worktable 2. Two rotating rods 53 are rotatably connected inside the sliding plate 52. The sliding plate 52 connects the two rotating rods 53 via two shafts, and the sliding of the sliding plate 52 drives the two rotating rods 53 to rotate. Both rotating rods 53 are internally connected to rotating shafts 54. The two rotating rods 53 provide support for the rotation of the two rotating shafts 54, preventing the two rotating shafts 54 from shaking during rotation and thus improving the rotational stability of the two rotating shafts 54. A rubber plate 55 is fixedly connected to the outside of the rotating shafts 54. The rubber plate 55 is elastic and can play a role in cushioning and anti-slip when positioning parts, avoiding damage to the surface of the parts. Two rubber plates 55 are slidably connected to the top of the worktable 2 at their bottoms. The worktable 2 provides support for the sliding of the two rubber plates 55, preventing them from shifting during the sliding process and thus improving the positioning stability of the two rubber plates 55 for the parts. Two support shafts 56 are fixedly connected inside the support frame 3, providing guide support. The support frame 3 provides fixation for the two support shafts 56, thus improving the support stability of the two support shafts 56. Two rotating shafts 54 are slidably connected to the outside of the two support shafts 56, providing guide support for the two rotating shafts 54 and preventing them from shifting during the sliding process, thus improving the stability of the two rotating shafts 54 in clamping the parts. Two slide rails 57 are provided at the top of the worktable 2. The outside of the two rotating shafts 54 are slidably connected to the inside of the two slide rails 57. The inside of the two slide rails 57 is adapted to the two rotating shafts 54, providing limits for the sliding of the two rotating shafts 54 and preventing them from shifting during the sliding process, thereby improving the sliding stability of the two rotating shafts 54. Reference Figures 2 to 4The fixing mechanism 6 includes two fixing rings 61, which are externally fixedly connected to the inside of the fixing plate 42. The fixing rings 61 provide sliding support, and the fixing plate 42 fixes the two fixing rings 61, thereby improving the support stability of the two fixing rings 61. A sliding shaft 62 is slidably connected inside the fixing rings 61. The fixing rings 61 guide the sliding of the sliding shaft 62, preventing the sliding shaft 62 from deviating during sliding, thereby improving the sliding stability of the sliding shaft 62. A sliding rod 63 is slidably connected inside the sliding shaft 62. The sliding shaft 62 has a groove inside, which guides the sliding of the sliding rod 63, preventing the sliding rod 63 from deviating during sliding, thereby improving the sliding stability of the sliding rod 63. A limiting ring 64 is externally fixedly connected to the sliding shaft 62 by welding. The sliding of the sliding shaft 62 moves the limiting ring 64 within the fixing rings 61. A spring 65 is sleeved on the outside of the sliding shaft 62. The sliding shaft 62 provides support for the spring 65, so that the spring 65 is evenly stressed, thereby improving the service life of the spring 65. The bottoms of two springs 65 are fixedly connected to the inside of two fixed rings 61, which provide support for the springs 65, reduce the pressure on the fixed rings 61, and thus improve the efficiency of the fixed rings 61. The tops of two springs 65 are fixedly connected to the bottoms of two limiting rings 64, respectively. The sliding shaft 62 drives the limiting rings 64 to compress the springs 65, causing the springs 65 to deform under force. The bottom of the sliding rod 63 is fixedly connected to a connecting shaft 66, which drives the connecting shaft 66 to slide synchronously. Both ends of the connecting shaft 66 are fixedly connected to limiting shafts 67, which slide along the connecting shaft 66. Rotating blocks 68 are rotatably connected to the outside of each limiting shaft 67. The two limiting shafts 67 are the rotation center shafts, providing support for the rotation of the two rotating blocks 68, preventing the two rotating blocks 68 from shifting during rotation, and thus improving the rotational stability of the rotating blocks 68. Each of the multiple rotating blocks 68 has a sliding groove inside. The sliding groove inside the rotating block 68 is adapted to the shape of the connecting shaft 66 and the limiting shaft 67, providing guidance for the sliding of the connecting shaft 66 and the limiting shaft 67. Two rotating blocks 68 are externally rotatably connected to the interior of a sliding shaft 62. The sliding shaft 62 has grooves inside, providing space for the rotation of the rotating blocks 68. The sliding of the sliding shaft 62 causes the rotating blocks 68 to slide synchronously. A connecting shaft 66 is externally slidably connected to the interior of the two rotating blocks 68. The two rotating blocks 68 guide the sliding of the connecting shaft 66. The sliding of the connecting shaft 66 causes a limiting shaft 67 to slide inside the rotating blocks 68. This, in conjunction with the inclined grooves inside the rotating blocks 68, allows the connecting shaft 66 to drive the limiting shaft 67, thus unfolding the two rotating blocks 68. A stamping die 7 slides externally to the two rotating blocks 68. The stamping die 7 has multiple grooves inside, adapted to the shape of the rotating blocks 68. When the two rotating blocks 68 are unfolded, the sliding of the sliding shaft 62 causes the two rotating blocks 68 to embed into the interior of the stamping die 7, thereby fixing the stamping die 7. The sliding shaft 62 is externally slidably connected to the inside of the stamping die 7. The stamping die 7 provides sufficient sliding space for the sliding shaft 62 to slide. By pressing the sliding shaft 62, the sliding shaft 62 slides inside the stamping die 7, thereby providing operating space for the unfolding of the rotating block 68.
[0014] Working principle: When precision machining a part, cylinder 511 is first activated, which drives drive shaft 512 to move. The movement of drive shaft 512 pushes sliding plate 52 to slide inside worktable 2. Sliding plate 52 drives two rotating rods 53 to rotate through two shafts. The rotation of the two rotating rods 53 drives two rotating shafts 54 to move. Through the limiting of two support shafts 56 and two slide rails 57, the two rotating shafts 54 slide inside the two slide rails 57 at the top of worktable 2. The relative sliding of the two rotating shafts 54 drives rubber plate 55 to slide synchronously. By bringing the two rubber plates 55 closer to each other, their elastic properties are used to clamp and position the part, thereby improving the stability of the part and preventing damage to the surface of the part. After the part is positioned, cylinder 41 is activated, causing the fixed plate 42 to move, which in turn drives the stamping die 7 to process the part. When the stamping die 7 is replaced or maintained, the sliding shaft 62 is pressed first, causing it to slide inside the stamping die 7. At this time, the sliding shaft 62 drives the connecting shaft 66 to slide, which in turn drives the two limiting shafts 67 to slide. The two limiting shafts 67 then drive the two rotating blocks 68 to rotate, causing the two rotating blocks 68 to leave the inside of the stamping die 7, thus separating the stamping die 7. The sliding shaft 62 drives the limiting ring 64 to compress the spring 65, causing the spring 65 to deform. At the same time, the sliding rod 63 inside the sliding shaft 62 drives the connecting shaft 66 to slide. The sliding of the connecting shaft 66 causes the limiting shaft 67 to slide in the groove of the rotating block 68. With the bevel design of the groove, the two rotating blocks 68 are unfolded. The unfolded rotating blocks 68 are embedded in the interior of the stamping die 7. The spring 65 releases the elastic force, allowing the sliding shaft 62 to slide and be positioned inside the stamping die 7, thereby achieving a firm installation of the stamping die 7 and improving the efficiency of the stamping die 7.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
