Description

Technical Field

[0001] This application relates to the field of sheet metal mold technology, and in particular to a sheet metal forming mold. Background Technology

[0002] Sheet metal forming dies are molds used to process sheet metal into metal parts of desired shapes and sizes through cold stamping or hydroforming. Sheet metal forming dies are widely used in machinery, automotive, aerospace, home appliances, and construction industries, and are characterized by high precision, high efficiency, and long service life.

[0003] Patent CN221158321U discloses "a sheet metal mold that is easy to disassemble, including a processing table, a mounting frame installed on the top of the processing table, and a first electric telescopic rod installed on the top of the mounting frame. This invention allows for the disassembly of the upper and lower sheet metal molds by pressing the rod inward, causing the mounting plate to move inside the receiving groove, thus completely separating the second threaded rod from the through hole. The upper sheet metal mold moves downward and the lower sheet metal mold moves upward, completely separating the slot and the locking block, the connecting slot and the connecting block, thereby achieving the disassembly of the upper and lower sheet metal molds. Reversing the operation allows for installation. The operation is simple and convenient, enabling partial replacement of sheet metal molds, reducing the footprint of mechanical equipment, lowering subsequent maintenance costs, and expanding the applicability of the device."

[0004] Regarding the aforementioned related technologies, the inventor believes that when installing the mold, it is necessary to first push the push rod inward to the mounting base, then insert the connecting block into the mounting base, then release the push rod to use the second threaded rod to insert the connecting block, and finally screw the rotating block on the outside of the second threaded rod for tightening. This makes the overall mold installation process time-consuming and inconvenient, and therefore needs to be improved. Utility Model Content

[0005] To address the aforementioned problems, this application provides a sheet metal forming mold.

[0006] The sheet metal forming mold provided in this application adopts the following technical solution:

[0007] A sheet metal forming mold includes a mold body, a base disposed at the bottom of the mold body for mounting the mold body, and a connecting mechanism disposed between the mold body and the base. The connecting mechanism includes two sets of mounting slots opened at the top of the base and two sets of mounting rods fixedly disposed at the bottom of the mold body and fitted into the mounting slots. A positioning mechanism is provided between the mold body and the base. A ratchet and a pawl are rotatably disposed in the mounting slots of the base. A plurality of helical teeth are fixedly provided on one side of the mounting rod, evenly distributed along the length of the mounting rod and meshing with the ratchet. Pulling mechanisms are provided on both sides of the base for pulling the pawl away from the ratchet to disassemble the mold body.

[0008] By adopting the above technical solution, the mold body and the base are connected by inserting the mounting rod into the corresponding mounting slot. At the same time, when the mounting rod is inserted, the helical teeth drive the ratchet to rotate in one direction. The self-locking between the ratchet and the pawl can fix the inserted mounting rod, thereby installing the mold body. The entire process of installing and fixing the mold body can be completed simply by inserting the mounting rod completely into the mounting slot.

[0009] Preferably, the positioning mechanism includes a positioning hole at the bottom of the mounting rod and a positioning post fixed to the bottom of the mounting groove of the base and inserted into the positioning hole.

[0010] By adopting the above technical solution, the positioning post will automatically insert into the corresponding positioning groove during the insertion of the installation rod, thereby positioning the installation rod.

[0011] Preferably, a first rotating rod is rotatably provided in the mounting groove of the base, the ratchet is fixedly connected to the outer wall of the first rotating rod, and a second rotating rod is rotatably provided in the mounting groove of the base, with one end of the pawl fixedly connected to the outer wall of the second rotating rod.

[0012] By adopting the above technical solution, the first rotating rod can connect the base and the ratchet, so that the ratchet can rotate inside the base, and the second rotating rod can connect the base and one end of the pawl, so that the pawl can rotate inside the base.

[0013] Preferably, a metal spring for pushing the pawl toward the ratchet is fixed in the mounting groove of the base, and the pulling mechanism includes a connecting rope fixed on the side of the pawl away from the ratchet and passing through the base, and two sets of pull rods fixed between adjacent connecting ropes and located outside the base.

[0014] By adopting the above technical solution, the elasticity of the metal spring can press the pawl onto the ratchet to ensure the stability of the mounting rod and the mold body after installation. Furthermore, by pulling the pull rod outward from the base, the pawl can be pulled away from the ratchet in conjunction with the connecting rope, allowing the mounting rod to be pulled out of the mounting slot for disassembly and quick replacement of the mold body.

[0015] Preferably, the base has support rings on both sides for lifting and limiting the pull rod after it is pulled, and two sets of fixing rods are fixedly provided on both sides of the base, with the support rings fixedly provided at one end of the fixing rods.

[0016] By adopting the above technical solution, the pulled rod can be snapped into the support ring after being pulled, and the elasticity of the metal spring can fix the snapped rod, so that the workers do not need to pull the rod continuously during the disassembly process.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The mold body is connected to the base by inserting the mounting rod into the corresponding mounting slot. When the mounting rod is inserted, the helical teeth drive the ratchet to rotate in one direction. The self-locking between the ratchet and the pawl fixes the inserted mounting rod, thereby installing the mold body. The positioning pin automatically inserts into the corresponding positioning slot during the insertion of the mounting rod, thereby positioning the mounting rod. The entire process of installing and fixing the mold body can be completed simply by inserting the mounting rod completely into the mounting slot, which is more convenient and faster.

[0019] 2. The elasticity of the metal spring clips presses the pawl against the ratchet, ensuring the stability of the mounting rod and mold body after installation. By pulling the lever outward from the base, the pawl can be pulled away from the ratchet using the connecting rope, allowing the mounting rod to be pulled out of the mounting slot for disassembly and quick replacement of the mold body. The pulled lever can then be engaged in the retaining ring, and the elasticity of the metal spring clips secures the engaged lever, eliminating the need for operators to continuously pull the lever during disassembly, thus facilitating operation.

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses a sheet metal forming mold.

[0027] A sheet metal forming mold, as shown in the figure Figure 1-3It includes a mold body 1, a base 2 and a connecting mechanism. The base 2 is located at the bottom of the mold body 1. The base 2 can be used to install the mold body 1 and can support the mold body 1. The mold body 1 is an existing sheet metal forming mold, which will not be described in detail here.

[0028] Reference Figure 2 and Figure 4 The connecting mechanism includes two sets of mounting slots 21 on the top of the base 2 and two sets of mounting rods 11 fixed on the bottom of the mold body 1 and inserted into the mounting slots 21. After the mounting rods 11 are inserted into the corresponding mounting slots 21, they can connect the mold body 1 and the base 2.

[0029] Reference Figure 2 and Figure 4 A positioning mechanism is provided between the mold body 1 and the base 2. The positioning mechanism includes a positioning hole 12 opened at the bottom of the mounting rod 11 and a positioning pin 22 fixed at the bottom of the mounting groove 21 of the base 2 and inserted into the positioning hole 12. During the process of the mounting rod 11 being inserted into the corresponding mounting groove 21, the positioning pin 22 will also be automatically inserted into the positioning hole 12 of the mounting rod 11, thereby positioning the mounting rod 11 and the mold body 1, so that the mold body 1 can only move up and down.

[0030] Reference Figure 2 and Figure 4 A ratchet 3 and a pawl 31 are rotatably mounted in the mounting groove 21 of the base 2. A first rotating rod 34 is rotatably mounted in the mounting groove 21 of the base 2. The ratchet 3 is fixedly connected to the outer wall of the first rotating rod 34. A second rotating rod 35 is rotatably mounted in the mounting groove 21 of the base 2. One end of the pawl 31 is fixedly connected to the outer wall of the second rotating rod 35. A metal spring 33 for pushing the pawl 31 toward the ratchet 3 is fixedly mounted in the mounting groove 21 of the base 2. The first rotating rod 34 can connect the base 2 and the ratchet 3, so that the ratchet 3 can rotate within the base 2. The second rotating rod 35 can connect the base 2 and one end of the pawl 31, so that the pawl 31 can rotate within the base 2. The metal spring 33 can firmly press the pawl 31 onto the ratchet 3 under its own elastic force, so that the ratchet 3 can only rotate in one direction.

[0031] Reference Figure 2 and Figure 4 The mounting rod 11 is fixed with a number of helical teeth 32 that are evenly distributed along the length of the mounting rod 11 and mesh with the ratchet 3. When the mounting rod 11 is inserted into the mounting groove 21, the lowered mounting rod 11 will drive the meshing ratchet 3 to rotate in one direction by the helical teeth 32. The self-locking between the ratchet 3 and the pawl 31 will fix the inserted mounting rod 11, thereby installing and fixing the mold body 1.

[0032] Reference Figure 2-4The base 2 has a pulling mechanism on both sides for pulling the pawl 31 away from the ratchet 3 to disassemble the mold body 1. The pulling mechanism includes a connecting rope 4 fixed on the side of the pawl 31 away from the ratchet 3 and passing through the base 2, and two sets of pull rods 41 fixed between adjacent connecting ropes 4 and located outside the base 2. The connecting rope 4 can connect the pawl 31 and the pull rod 41. The operator can pull the pull rod 41 to the outside of the base 2, which can cooperate with the connection of the connecting rope 4 to pull the pawl 31 away from the ratchet 3. At this time, the mounting rod 11 will be disengaged. Then the operator can pull the mounting rod 11 out of the mounting groove 21 to disassemble and quickly replace the mold body 1.

[0033] Reference Figure 2-4 The base 2 has rings 5 ​​on both sides for supporting and limiting the pull rod 41 after it is pulled. Two sets of fixing rods 51 are fixed on both sides of the base 2. The rings 5 ​​are fixed at one end of the fixing rods 51. The fixing rods 51 can connect the rings 5 ​​to the base 2. The operator can put the pulled rod 41 into the rings 5 ​​after it is pulled. At this time, under the elasticity of the metal spring 33 and the pull of the connecting rope 4, the pulled rod 41 that is put into the rings 5 ​​can be fixed, so that the operator does not need to pull the rod 41 all the time during the disassembly process, which is convenient for operation.

[0034] The implementation principle of a sheet metal forming mold in this application embodiment is as follows:

[0035] When installing the mold body 1, the operator can slowly lift the mold body 1 to the top of the base 2 so that the mounting rod 11 can be inserted into the corresponding mounting slot 21 to make a preliminary connection between the mold body 1 and the base 2. During the process of the mounting rod 11 being inserted into the corresponding mounting slot 21, the positioning pin 22 will also be automatically inserted into the positioning hole 12 of the mounting rod 11 to position the mounting rod 11 and the mold body 1.

[0036] As the mounting rod 11 is inserted into the mounting slot 21, the lowered mounting rod 11 will drive the meshing ratchet 3 to rotate in one direction using the helical teeth 32. The self-locking energy between the ratchet 3 and the pawl 31 will fix the inserted mounting rod 11, thereby installing and fixing the mold body 1. The entire process of installing and fixing the mold body 1 can be completed simply by fully inserting the mounting rod 11 into the mounting slot 21, which is more convenient and faster.

[0037] When it is necessary to disassemble the mold body 1, the operator can pull the pull rod 41 outward to the base 2, which, in conjunction with the connection of the connecting rope 4, pulls the pawl 31 away from the ratchet 3. At this time, the mounting rod 11 will be disengaged. Then, the operator can pull the mounting rod 11 out of the mounting groove 21 to quickly disassemble the mold body 1. During disassembly, the operator can snap the pulled rod 41 into the support ring 5. At this time, under the elasticity of the metal spring 33 and the pull of the connecting rope 4, the pull rod 41 snapped into the support ring 5 can be fixed, so that the operator does not need to keep pulling the pull rod 41 during the disassembly process, which is convenient for operation. By disassembling and assembling the mold body 1, the mold body 1 can be quickly replaced.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
