Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, specifically to a self-positioning locking mold frame for modular quick-change molds of forgings. Background Technology

[0002] Die forging is one of the core processes of metal plastic forming. It refers to the process in which a metal billet is subjected to impact or pressure in the cavity of a die, undergoes plastic deformation and fills the cavity, and finally obtains a forging that meets the requirements in terms of shape, dimensional accuracy and mechanical properties.

[0003] The forging die holder is an important component of the forging die. It is mainly used to fix and support the die inserts, ensure the relative position accuracy of the upper and lower dies, and transmit pressure and ejection force. When fixing the die, bolts and pressure plates are usually used to fix the die on the die holder, and the die on the die holder is positioned and installed by manually aligning the guide pillars.

[0004] Considering that existing mold racks require manual alignment of the mold with guide pillars and sequential tightening of multiple bolts to secure the mold during mold replacement, and that multiple bolts need to be tightened in the opposite direction during mold disassembly, the efficiency of mold replacement is reduced, which in turn reduces the working efficiency and effectiveness of the mold rack. Utility Model Content

[0005] The purpose of this utility model is to provide a self-positioning locking mold frame for modular quick-change molds of forgings. It mainly solves the problem that the mold frame needs to be manually aligned with the guide pillars and multiple bolts are screwed in sequence for fixing or disassembling when it is installed on the mold frame, which reduces the working efficiency and the effect of the mold frame.

[0006] To achieve this objective, the present invention adopts the following technical solution: This utility model provides a self-positioning locking mold frame for modular quick-change molds of forgings, including a base, a worktable and a mold. The worktable is fixedly installed on the base, and the mold can be installed and removed from the worktable through a fixing mechanism. The fixing mechanism is used to position and fix the mold. The fixing mechanism includes a positioning plate, a moving plate, and a wedge. The positioning plate is fixedly installed on the worktable, the moving plate is slidably installed on the worktable, and the wedge is slidably installed on the moving plate via a guide rod, which is connected to the moving plate via a spring.

[0007] Furthermore, the fixing mechanism also includes a rotating plate and a cylindrical rod. The rotating plate is rotatably mounted on the bottom of the worktable, and the rotating plate is hinged to the cylindrical rod via a hinge rod. The cylindrical rod is fixedly mounted on the bottom of the movable plate, and the cylindrical rod passes through the worktable.

[0008] Furthermore, the fixing mechanism also includes a motor, which is fixedly mounted on the base, and the output shaft of the motor is fixedly connected to the rotating plate.

[0009] Furthermore, the fixing mechanism also includes a plug-in post. The mold has a plug-in hole, the plug-in post is fixedly installed on the positioning plate, and the plug-in post is plugged into the plug-in hole.

[0010] Furthermore, the fixing mechanism also includes a rubber pad and a positioning mechanism. The rubber pad is fixedly installed on the moving plate, and the positioning mechanism is used to position the mold.

[0011] Furthermore, the positioning mechanism includes a cylindrical tube and an abutment plate. The mold has a positioning hole, the cylindrical tube is fixedly installed on the movable plate, and the cylindrical tube is inserted into the positioning hole. The cylindrical tube has a sliding groove, and the abutment plate is slidably connected to the sliding groove through a T-block.

[0012] Furthermore, the positioning mechanism also includes a pressing column, which is slidably mounted on the cylindrical tube via a baffle and penetrates through the cylindrical tube. The pressing column is hinged to the abutment plate via a connecting rod.

[0013] Furthermore, the baffle and the cylindrical tube are connected by a return spring.

[0014] The beneficial effects of this utility model are as follows: This modular quick-change mold for forging uses a self-positioning locking mold frame. Through the setting of the fixing mechanism, the positioning plate and the moving plate can play a positioning and clamping role on the mold, thereby enabling the mold to be quickly positioned and fixed on the worktable or disassembled, thus improving the working efficiency and use effect of the mold frame. In addition, through the setting of the positioning mechanism, the insertion of the cylindrical tube into the positioning hole can further play a positioning role on the mold, preventing the mold from shaking or shifting during operation, thereby improving the fixing effect and stability of the mold.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] Reference Figures 1 to 5 The self-positioning locking mold frame for modular quick-change molds of forgings shown includes a base 1, a worktable 2 and a mold 3. The worktable 2 is fixedly installed on the base 1 and is used to support and fix the mold 3. The mold 3 can be installed and removed from the worktable 2 through a fixing mechanism 4. The fixing mechanism 4 is used to position and fix the mold 3 and achieve the effect of quick mold replacement, thereby improving the working efficiency of the mold frame. The fixing mechanism 4 includes a positioning plate 41, a movable plate 46, and a wedge 410. The positioning plate 41 is fixedly installed on the worktable 2 and is used to limit the position of the mold 3. The movable plate 46 is slidably installed on the worktable 2. There are two movable plates 46 symmetrically distributed. Through the movement of the two movable plates 46, the mold 3 can be clamped and fixed. The wedge 410 is slidably installed on the movable plate 46 through a guide rod 412. The guide rod 412 is connected to the movable plate 46 through a spring 411. Through the elastic force of the spring 411, the guide rod 412 drives the wedge 410 to move closer to the movable plate 46. During the process of the movable plate 46 moving to clamp the mold 3, the wedge 410 can push the mold 3 against the positioning plate 41, thereby achieving the positioning and fixing function.

[0021] Reference Figure 1 and Figure 4Specifically, the fixing mechanism 4 also includes a rotating plate 44 and a cylindrical rod 47. The rotating plate 44 is rotatably mounted on the bottom of the worktable 2, and the rotating plate 44 is hinged to the cylindrical rod 47 via a hinge rod 45. The rotation of the rotating plate 44 can drive the hinge rod 45 to move, thereby driving the cylindrical rod 47 to move. The cylindrical rod 47 is fixedly mounted on the bottom of the moving plate 46, and the cylindrical rod 47 passes through the worktable 2. The movement of the cylindrical rod 47 can drive the moving plate 46 to move. The fixing mechanism 4 also includes a motor 43, which is fixedly mounted on the base 1, and the output shaft of the motor 43 is fixedly connected to the rotating plate 44. Starting the motor 43 can drive the rotating plate 44 to rotate.

[0022] Reference Figure 2 and Figure 4 More specifically, the fixing mechanism 4 also includes a plug-in post 42. The mold 3 has a plug-in hole 413. The plug-in post 42 is fixedly installed on the positioning plate 41, and the plug-in post 42 is plugged into the plug-in hole 413. When the mold 3 is pushed close to the positioning plate 41 by the moving plate 46 and the wedge 410, the plug-in post 42 will plug into the plug-in hole 413, thereby positioning the mold 3. The fixing mechanism 4 also includes a rubber pad 48 and a positioning mechanism 49. The rubber pad 48 is fixedly installed on the moving plate 46 and is installed on the clamping surface of the moving plate 46 to enhance the clamping effect of the moving plate 46 on the mold 3. The positioning mechanism 49 is used to position the mold 3, thereby further improving the fixing effect of the mold 3 and preventing the mold 3 from shaking or shifting during operation.

[0023] Reference Figures 6 to 8 In addition, the positioning mechanism 49 includes a cylindrical tube 491 and an abutment plate 493. The mold 3 has a positioning hole 499. The cylindrical tube 491 is fixedly installed on the movable plate 46 and is inserted into the positioning hole 499. Through the insertion effect of the cylindrical tube 491 and the positioning hole 499, the mold 3 can be further positioned and fixed. The cylindrical tube 491 has a sliding groove 492, which is used to guide the T-block 494 and the abutment plate 493. The abutment plate 493 is slidably connected to the sliding groove 492 through the T-block 494. Multiple abutment plates 493 are provided. Through the movement effect of the abutment plates 493, the abutment plates 493 can abut against the inner wall of the positioning hole 499, avoiding the gap between the positioning hole 499 and the cylindrical tube 491, which would cause the mold 3 to shake.

[0024] Reference Figure 6The positioning mechanism 49 also includes a pressing column 496, which is slidably mounted on the cylindrical tube 491 via a baffle 497 and penetrates the cylindrical tube 491. When the cylindrical tube 491 is inserted into the positioning hole 499, the inner wall of the positioning hole 499 can press the pressing column 496. The pressing column 496 is hinged to the abutment plate 493 via a connecting rod 495. When the pressing column 496 is pressed and moves, it can drive the connecting rod 495 to move, causing the abutment plate 493 to move. The baffle 497 and the cylindrical tube 491 are connected by a return spring 498. Through the elastic force of the return spring 498, the baffle 497 can drive the pressing column 496 to move away from the cylindrical tube 491, thereby driving the abutment plate 493 to move into the cylindrical tube 491.

[0025] Reference Figures 1 to 8 The modular quick-change mold for this forging uses a self-positioning locking mold frame. In actual operation, the mold 3 is manually placed in the middle of the workbench 2. The motor 43 is started to drive the rotating plate 44 to rotate, which causes the hinge rod 45 to drive the cylindrical rod 47 to move, thereby driving the moving plate 46 to move and clamp the mold 3. At the same time, during the movement of the moving plate 46, the spring 411 drives the guide rod 412 to drive the wedge block 410 to press the mold 3 towards the positioning plate 41. This allows the moving plate 46 and the wedge block 410 to push the mold 3 to fit against the positioning plate 41, and allows the insertion post 42 to insert into the insertion hole 413, thus positioning and fixing the mold 3.

[0026] When the mold 3 is in contact with the positioning plate 41, the cylindrical tube 491 on the moving plate 46 can be inserted into the positioning hole 499 on the mold 3, so that the extrusion column 496 is squeezed by the inner wall of the positioning hole 499, which drives the connecting rod 495 to move, thereby driving multiple abutment plates 493 to move and abut against the inner wall of the positioning hole 499 to fix it, thereby further improving the positioning and fixing effect of the mold 3 and preventing the mold 3 from shaking or shifting during operation.

[0027] When it is necessary to replace mold 3, the motor 43 is started to rotate in the reverse direction, thereby driving the moving plate 46 to move in the reverse direction, releasing the clamping and fixing effect on mold 3, and at the same time releasing the insertion of cylindrical cylinder 491 and positioning hole 499, so that the return spring 498 drives the extrusion column 496 and the abutment plate 493 to reset, thus making it easy for manual removal of mold 3 for replacement.

[0028] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
