Description

Technical Field

[0001] This utility model relates to the field of mold guiding technology, and in particular to a high-precision mold guiding mechanism. Background Technology

[0002] High-precision molds are typically used to manufacture products with extremely high requirements for precision and quality, such as precision instruments, electronic equipment, automotive parts, medical devices, and aerospace components. The performance and quality of these products directly affect the functionality and safety of the final product, necessitating high-precision molds to ensure high-precision manufacturing. Traditional stamping dies typically require guide rods for guidance during stamping to improve accuracy. After a certain period of use, the guide rods need to be lubricated periodically. However, lubricating oil is usually applied manually to each of the four guide rods in turn, which is cumbersome and inefficient. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for guide rods in traditional stamping dies to improve accuracy during stamping, the need for periodic lubrication of the guide rods after a certain period of use, and the cumbersome and inefficient manual application of lubricant to the four guide rods. Therefore, this invention proposes a high-precision die guiding mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision mold guiding mechanism includes a machine base and a guiding mechanism for guiding. The guiding mechanism includes four guide rods, the bottom ends of which are fixedly connected to the four corners of the top of the machine base. The top ends of the four guide rods are fixedly provided with the same top plate. The top of the machine base is provided with a movable plate, and each of the four corners of the movable plate has a movable hole. The outer side of each guide rod is slidably connected to the inner wall of the movable hole. The bottom of the movable plate is fixed with an upper mold by bolts, and the top of the machine base is fixed with a lower mold that cooperates with the upper mold by bolts. Each of the four corners of the top of the movable plate is fixed with a cover, and the guide rod is located inside the cover. The cover is provided with a coating mechanism, which can apply lubricating oil to the guide rod when it is necessary to lubricate it. To facilitate the application of the coating mechanism to the guide rod, a drive mechanism is also included. The drive mechanism can drive the coating mechanism to rotate and apply the coating to the guide rod.

[0005] In one possible design, the application mechanism includes a sponge block, an insert block, and a placement frame. One side of the sponge block is fixedly connected to one side of the insert block. The insert block is cross-shaped. The placement frame has a slot for use with the insert block. The insert block is inserted into the slot. One end of the sponge block is attached to one side of the guide rod.

[0006] In one possible design, the drive mechanism includes four motors and four gear rings. The bottom of the four motors is fixedly connected to the top side of the four covers, respectively. The output end of the motor passes through the top of the cover and is fixedly equipped with a gear. Bearings are fixedly installed at the four corners of the top of the moving plate. The bottom of the four gear rings is fixedly connected to the top of the inner ring of the four bearings, respectively. The gears mesh with the gear rings. The bottom of the placement frame is fixedly connected to the top side of the gear rings.

[0007] In one possible design, a fixing strap for blocking and fixing the top of the insert is fixedly provided on one side of the placement rack. One end of the fixing strap is sewn with a hook and loop fastener. A hook and loop fastener for cooperating with the hook and loop fastener is fixedly provided on the other side of the placement rack. The hook and loop fastener are bonded to each other.

[0008] In one possible design, a frame is fixedly installed on one side of the machine tool. The frame is U-shaped, and an L-shaped insert plate is inserted into the frame. A storage box for placing a lubricating oil bottle is fixedly installed on one side of the insert plate.

[0009] In one possible design, a driving component for driving the upper mold to press down is fixedly installed on the top of the top plate, and the telescopic part of the driving component passes through the top of the top plate and is fixedly connected to the top of the movable plate.

[0010] In one possible design, the top of the insert block is fixedly provided with a handle to facilitate pulling the insert block out of the placement rack.

[0011] In this application, during installation, pick up the sponge block, align the fixed insert on one side with the slot on the placement rack, and gently insert the insert into the slot until it is fully inserted. The sponge block has a certain length, and one end of the sponge block will adhere to one side of the guide rod. Pull the fixing strap to wrap it around the top of the insert, and then attach the Velcro side of one end of the fixing strap to the Velcro hook side of the placement rack to hold and fix the insert, preventing it from loosening during the application process. When the guide rod needs to be lubricated, the operator takes a lubricating oil bottle and squeezes the lubricating oil into the sponge block, allowing the sponge block to absorb the lubricating oil. Start the four motors, and the output of the motors drives the gears to rotate, which in turn drives the gear ring to rotate. The gear ring rotates under the support of the bearing, and the rotation of the gear ring drives the rotation of the placement rack and the sponge block. The sponge block rotates around the guide rod, and as the sponge block rotates, the lubricating oil is applied to the surface of the guide rod. During the application process, the drive unit is activated simultaneously, extending its telescopic part to push the moving plate downwards along the guide rod. This also moves the sponge block, allowing it to coat the surface of the guide rod. After coating, the motor is turned off. During stamping, the workpiece is placed on the lower mold, and the drive unit is activated again, extending its telescopic part to push the moving plate downwards along the guide rod. This causes the upper mold to move downwards and close with the lower mold. During mold closing, the guide rod provides precise guidance, ensuring accurate fit between the upper and lower molds and guaranteeing the precision of the molded product. After the upper and lower molds close, the product is pressed down and formed. The drive unit can be one of the following: a pneumatic cylinder (requires an external air source), a hydraulic cylinder (requires an external hydraulic pump station), or an electric push rod (requires an external power supply). The appropriate type can be selected based on actual needs. It is important to note that the motor and drive unit require an external controller and an external power supply for operation.

[0012] The beneficial effects of this utility model are as follows: In this utility model, a high-precision mold guiding mechanism is provided. Through an application mechanism and a driving mechanism, the output end of the motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring rotates under the support of the bearing. The rotation of the gear ring drives the placement rack and the sponge block to rotate. The sponge block rotates around the guide rod, and as the sponge block rotates, lubricating oil is applied to the surface of the guide rod. In this utility model, the high-precision mold guiding mechanism has a sponge block of the coating mechanism that is inserted into a slot on the placement rack via an insert block and fixed by a fixing strap and Velcro. When the sponge block affects the coating effect due to wear or excessive adsorption of impurities, simply peel off the adhesive between the hook side and the loop side of the Velcro, and then hold the handle at the top of the insert block to easily pull the insert block out of the slot on the placement rack, replace it with a new sponge block and insert block, and re-fix the fixing strap. This design makes the replacement of the sponge block simple and quick, and improves the maintenance efficiency of the equipment. In this invention, the application mechanism and the drive mechanism can apply lubricating oil to the surface of the guide rod, which greatly improves lubrication efficiency and saves manpower and time costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1-5 A guiding mechanism is disclosed, comprising a machine base 1, a guiding mechanism, a movable plate 3, an upper mold, a lower mold 6, a coating mechanism, a driving mechanism, a placement box 7, and a driving component 5, etc., designed to achieve precise guidance during the mold stamping process and improve the convenience and efficiency of lubrication of the guide rods 2. The machine base 1 serves as the basic support component of the entire mold guiding mechanism, with the bottom ends of four guide rods 2 fixedly connected to its four corners. A top plate 4 is fixedly mounted on the top of the four guide rods 2, forming a stable guiding frame. The movable plate 3 is located on the top of the machine base 1, with movable holes at each of its four corners. The outer sides of the guide rods 2 are slidably connected to the inner walls of the movable holes, ensuring that the movable plate 3 can move smoothly up and down along the guide rods 2.

[0017] The bottom of the movable plate 3 is fixed with an upper mold by bolts, and the top of the machine base 1 is fixed with a lower mold 6 that works with the upper mold by bolts. During the stamping process, the upper mold and the lower mold 6 are precisely guided by the guide rod 2 to achieve mold closing, ensuring the accuracy of the molded product.

[0018] The application mechanism includes a sponge block 13, an insert block 16, and a placement rack 14. One side of the sponge block 13 is fixedly connected to one side of the insert block 16. The insert block 16 is cross-shaped, and the placement rack 14 has a slot for use with the insert block 16.

[0019] During installation, the operator picks up the sponge block 13, aligns the fixed insert 16 on one side with the slot on the placement bracket 14, and gently inserts the insert 16 into the slot until it is fully inserted. At this point, one end of the sponge block 13 will be in contact with one side of the guide rod 2, preparing for subsequent lubrication application.

[0020] To prevent the insert 16 from loosening during application, a fixing strap 15 is fixedly installed on one side of the holder 14. One end of the fixing strap 15 is sewn with a Velcro surface, and the other side of the holder 14 is fixedly installed with a Velcro hook surface 17 that mates with the Velcro surface. The operator pulls the fixing strap 15 to wrap it around the top of the insert 16, and then attaches the Velcro surface of one end of the fixing strap 15 to the Velcro hook surface 17 on the other side of the holder 14, thereby securing the insert 16. In addition, to facilitate subsequent replacement of the sponge block 13, a handle is fixedly installed on the top of the insert 16, allowing the operator to easily pull the insert 16 out of the holder 14.

[0021] The drive mechanism includes four motors 10 and four gear rings 11. The bottom of the four motors 10 is fixedly connected to one side of the top of the four covers 9 respectively, and the output end of the motor 10 passes through the top of the cover 9 and is fixedly equipped with gears.

[0022] Bearings 12 are fixedly installed at the four corners of the top of the movable plate 3. The bottom of the four toothed rings 11 are fixedly connected to the top of the inner ring of the four bearings 12 respectively. The gears mesh with the toothed rings 11. The bottom of the placement frame 14 is fixedly connected to one side of the top of the toothed rings 11.

[0023] When lubrication of the guide rod 2 is required, the four motors 10 are started. The output of the motors 10 drives the gears to rotate, and the gears drive the gear ring 11 to rotate. Since the gear ring 11 rotates under the support of the bearing 12, the rotation of the gear ring 11 will drive the placement rack 14 and the sponge block 13 to rotate around the guide rod 2, so that the lubricating oil on the sponge block 13 is applied to the surface of the guide rod 2.

[0024] This application is used in the field of high-precision mold guidance, but can also be used in other fields applicable to this application.

[0025] In another embodiment: Reference Figure 1-5 A high-precision mold guiding mechanism, which is used in the field of high-precision mold guiding. A frame is fixedly installed on one side of the machine 1. The frame is U-shaped, and an L-shaped insert plate 8 is inserted into the frame. A storage box 7 for placing lubricating oil bottles is fixedly installed on one side of the insert plate 8. When performing lubrication application, the operator can take out the lubricating oil bottle from the storage box 7 and squeeze the lubricating oil onto the sponge block 13, which is convenient and quick.

[0026] A drive component 5 for driving the upper die downward is fixedly installed on the top of the top plate 4. The telescopic part of the drive component 5 passes through the top of the top plate 4 and is fixedly connected to the top of the movable plate 3. The drive component 5 can be one of the following: a pneumatic cylinder (requiring an external air source), a hydraulic cylinder (requiring an external hydraulic pump station), or an electric push rod (requiring an external power supply). Users can flexibly choose according to actual production needs, site conditions, cost budget, and other factors. During stamping, the drive component 5 is activated, causing its telescopic part to extend, pushing the movable plate 3 downward along the guide rod 2, driving the upper die downward, and closing with the lower die 6 to complete the stamping of the product.

[0027] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive unit 5 and the motor 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0028] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
