Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a positioning and switching structure for stamping dies. Background Technology

[0002] Car sliding doors are sliding doors installed on automobiles to facilitate passenger entry and exit. They are commonly used in large buses, commercial vehicles, and some SUVs to provide more spacious entry and exit areas. The working principle of car sliding doors is based on the design of rails and rollers. The contact between the rails and rollers restricts the door's degree of freedom while guiding it to slide along a specific trajectory. When the sliding door slides on the guide rail, the opening and closing process is achieved through the contact between the rollers and the guide rail. However, during the production of car sliding doors, the delivery quantities of left and right sliding doors are inconsistent, and the mold parts for the left and right sides are produced simultaneously, resulting in an accumulation of stamped parts on one side. Each time there is a delivery on one side, it will increase the inventory of stamped parts on the other side. To address this, a positioning and switching structure for stamping dies is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning and switching structure for stamping dies to solve the problem mentioned in the background art that when producing automobile sliding doors, the delivery quantities of the left and right sliding doors are inconsistent, and the left and right parts of the die are produced at the same time, resulting in the accumulation of stamping parts on one side. Each time there is a delivery on one side, it will cause an increase in the inventory of stamping parts on the other side.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning and switching structure for a stamping die, comprising a die, pressure plates provided on both sides of the top of the die, connecting plates fixedly provided at both ends of the pressure plates, fixing bolts slidably provided inside the connecting plates and threadedly connected to the die, a first sliding rod slidably provided inside the pressure plates, a cover plate fixedly provided on the top of the first sliding rod, a spring sleeved on the outer side of the first sliding rod and the two ends of the spring fixedly connected to the cover plate and the pressure plate respectively, a mounting plate hinged to the bottom end of the first sliding rod, fixing rods fixedly provided at both ends of the mounting plate, a limit rod hinged to the outer side of the fixing rod and the limit rod penetrating the pressure plate, and clamping structures provided on both sides of the die.

[0005] Preferably, the clamping structure includes multiple fixed seats, which are respectively fixedly installed on both sides of the mold. A second sliding rod is slidably arranged inside each of the multiple fixed seats. A clamping plate is fixedly connected to one end of the second sliding rod. A horizontal plate is fixedly connected between one end of two second sliding rods at the same level. A limiting plate is fixedly arranged at the bottom of the horizontal plate. Threaded rods are fixedly arranged on both sides of the mold and the threaded rods pass through the limiting plates. A rotating plate is threadedly connected to the outer side of the threaded rods.

[0006] Preferably, the limiting rod has a connecting hole inside, the fixing rod passes through the connecting hole, and the diameter of the connecting hole is larger than the diameter of the fixing rod.

[0007] Preferably, the pressure plate has a first through hole inside, and the first sliding rod slides through the first through hole.

[0008] Preferably, the fixed base has a second through hole inside, and the second sliding rod slides through the second through hole.

[0009] Preferably, the rotating plate has a threaded hole inside, and the size of the threaded rod is adapted to the threaded hole.

[0010] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0011] This invention, by setting up a pressure plate, a first sliding rod, a cover plate, a spring, and a mounting plate, allows for the production of car sliding doors. When the material is placed on top of the mold, the limiting rod moves downwards, causing the spring on the outside of the first sliding rod to deform and slide the horizontal plate. The horizontal plate then pushes the clamping plate via the second sliding rod to clamp and limit the material at the top of the mold. After stamping, the spring drives the first sliding rod to reset, facilitating the next stamping. When single-piece stamping is required, the material is placed on the left or right side of the top of the mold as needed. The mold presses the limiting rod downwards, and the mounting plate drives another limiting rod upwards, thus limiting the material and facilitating single-sided stamping, avoiding material waste.

[0020] Example

[0021] In the existing technology, when producing car sliding doors, the inconsistent delivery quantities of the left and right sliding doors, coupled with the simultaneous production of the left and right mold parts, lead to an accumulation of stamped parts on one side. Each time a single side is delivered, it causes an increase in the inventory of stamped parts on the other side.

[0022] Please see Figure 1-4This utility model provides a technical solution: a positioning and switching structure for a stamping die, including a die 1. Pressure plates 2 are provided on both sides of the top of the die 1. Connecting plates 3 are fixedly provided at both ends of the pressure plates 2. Fixing bolts 4 are slidably provided inside the connecting plates 3 and are threadedly connected to the die 1. A first sliding rod 5 is slidably provided inside the pressure plates 2. A cover plate 6 is fixedly provided on the top of the first sliding rod 5. A spring 7 is sleeved on the outside of the first sliding rod 5, and both ends of the spring 7 are fixedly connected to the cover plate 6 and the pressure plates 2 respectively. A mounting plate 8 is hinged to the bottom end of the first sliding rod 5. Fixing rods 9 are fixedly provided at both ends of the mounting plate 8, and the outer sides of the fixing rods 9 are hinged to... The mold 1 has a limiting rod 10 that passes through the pressure plate 2. Both sides of the mold 1 are equipped with clamping structures. When producing a car sliding door, the material is placed on the top of the mold 1 and then stamped. This causes the limiting rod 10 to move downwards, and the spring 7 on the outside of the first sliding rod 5 will deform. After stamping, the spring 7 drives the first sliding rod 5 to return to its original position, facilitating the next stamping. When a single piece needs to be stamped, the material is placed on the left or right side as required. The mold will press the limiting rod 10 downwards, and the mounting plate 8 will drive the other limiting rod 10 upwards, thereby limiting the material and facilitating unilateral stamping of the material, avoiding material waste.

[0023] The clamping structure includes multiple fixed seats 11, which are respectively fixedly installed on both sides of the mold 1. A second sliding rod 12 is slidably arranged inside each of the multiple fixed seats 11. A clamping plate 13 is fixedly connected to one end of the second sliding rod 12. A horizontal plate 14 is fixedly connected between one end of two second sliding rods 12 at the same level. A limiting plate 15 is fixedly arranged at the bottom of the horizontal plate 14. Threaded rods 16 are fixedly arranged on both sides of the mold 1, and the threaded rods 16 pass through the limiting plate 15. A rotating plate 17 is threadedly connected to the outside of the threaded rods 16. In use, the second sliding rods 12 are slidably installed inside the fixed seats 11, and a clamping plate 13 is fixedly arranged at one end of the second sliding rods 12. When the material is placed on the top of the mold 1, the horizontal plate 14 is slid, and the horizontal plate 14 pushes the clamping plate 13 through the second sliding rods 12 to clamp and limit the material on the top of the mold 1. At the same time, the limiting plate 15 at the bottom of the horizontal plate 14 slides outside the threaded rods 16, and the rotating plate 17 is rotated to limit the limiting plate 15.

[0024] The limiting rod 10 has a connecting hole inside, and the fixing rod 9 passes through the connecting hole. The diameter of the connecting hole is larger than the diameter of the fixing rod 9. The limiting rod 10 is hinged to the mounting plate 8 through the fixing rod 9.

[0025] The pressure plate 2 has a first through hole inside, and the first sliding rod 5 slides through the first through hole. The mounting plate 8 is slidably mounted below the pressure plate 2 via the first sliding rod 5.

[0026] The fixed base 11 has a second through hole inside, the second sliding rod 12 slides through the second through hole, and the clamping plate 13 is slidably installed on the top of the mold 1 through the fixed base 11.

[0027] The rotating plate 17 has a threaded hole inside, and the threaded rod 16 is adapted to the size of the threaded hole. The limiting plate 15 is limited by rotating the threaded rod 16.

[0028] The working principle or structural principle is as follows: When producing a sliding car door, placing the material on the top of the mold 1 will cause multiple limiting rods 10 to move downwards. The limiting rods 10 will push the mounting plate 8 to move, and the spring 7 on the outside of the first sliding rod 5 will deform, sliding the horizontal plate 14. The horizontal plate 14 will push the clamping plate 13 through the second sliding rod 12 to clamp and limit the material on the top of the mold 1. At the same time, the limiting plate 15 at the bottom of the horizontal plate 14 slides on the outside of the threaded rod 16. The rotating plate 17 limits the limiting plate 15. After stamping, the spring 7 drives the first sliding rod 5 to reset, facilitating the next stamping. When single-piece stamping is required, the material is placed on the left or right side of the top of the mold 1 as needed. The mold will press the limiting rod 10 downwards, and the mounting plate 8 will drive another limiting rod 10 upwards, thereby limiting the material and facilitating single-sided stamping of the material, avoiding material waste.
