Description

Technical Field

[0001] This utility model belongs to the field of metal product processing technology, and in particular relates to processing molds for metal products. Background Technology

[0002] EI sheets are a type of core material widely used in electromagnetic devices such as electronic transformers. They are primarily composed of silicon steel sheets shaped like the letters "E" and "I," hence the name EI sheets. Silicon steel is a silicon-iron alloy with a silicon content of approximately 0.5%-4.5%. This material possesses high magnetic permeability and low iron loss. In electromagnetic devices, when current passes through a coil, a magnetic field is generated. EI sheets can effectively concentrate and guide this magnetic field, enhancing its strength. The two "E" and "I" shaped sheets combined together form a closed magnetic circuit, effectively reducing magnetic flux leakage and improving electromagnetic conversion efficiency. For example, in traditional power transformers, using EI sheets as the core reduces energy loss during the conversion of input voltage to different output voltages, making the transformer more efficient. Furthermore, the structure and characteristics of EI sheets also contribute to reducing transformer size, playing a positive role in the miniaturization design of electronic products.

[0003] Currently, EI wafer processing typically requires the use of die-forming equipment to assist in production. Chinese patent publication number "CN221694907U" discloses an EI wafer stamping device for convenient unloading. This device includes a stamping table, an L-shaped mounting bracket mounted on one side of the top of the stamping table, a mounting seat on the inner side of the L-shaped mounting bracket, and an upper stamping die mounted on the bottom of the mounting seat. Sliding rods are symmetrically mounted at both ends of the inner side of the L-shaped mounting bracket, with two sets of sliding rods passing through both ends of the top of the mounting seat. This device controls… The second drive device drives the octagonal prism to rotate 45° counterclockwise each time, so that the upper stamping die will be stamped with a different lower stamping die each time it extends and retracts. After each stamping process is completed, the lower stamping die will move away from directly below the upper stamping die. As the lower stamping die rotates downward, the EI sheet will automatically leave the lower stamping die due to gravity. This eliminates the need for manual removal of the finished EI sheet, ensuring the safety of the operator, and also automatically unloads and discharges the EI sheet after each stamping process.

[0004] The aforementioned equipment uses a rotating lower mold with multiple forming grooves for automatic demolding and unloading during processing. However, the molded products typically fall freely due to gravity. Since the EI sheet is shaped like a combination of the letters "E" and "I," its shape may cause jamming within the mold. If the EI sheet is not positioned accurately in the lower mold, or if the dimensional tolerances between the EI sheet and the lower mold are not properly matched (e.g., the EI sheet is slightly larger), it may become stuck in certain structural parts of the mold during mold closing and opening. This jamming may worsen when the mold is flipped. Because of its irregular shape, the EI sheet does not easily detach from the mold like regularly shaped parts; it may hook onto the internal structure of the mold, hindering normal mold flipping and automatic EI sheet discharge. Clearly, demolding is cumbersome and inconvenient, thus requiring improvement. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a processing mold for metal products to solve the problem that the existing technology cannot quickly and stably demold.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A metal product processing mold includes a fixed base frame, a fixed plate fixedly installed on the back of the fixed base frame, a stamping mechanism fixedly installed on the upper front end of the fixed plate, a driving mechanism movably installed on the front of the fixed plate inside the fixed base frame, an installation mechanism fixedly installed at the output end of the driving mechanism, lower molds installed at equal intervals on the outer side of the installation mechanism, and demolding mechanisms fixedly installed on the inner side of each lower mold.

[0008] The mounting mechanism includes a frame, which is fixedly mounted on the front of the drive mechanism. The outer side of the frame has mounting grooves at equal intervals. Slide plates are slidably connected to both sides of the inner side of the mounting grooves. The inner side of the slide plates is fixedly connected to both sides of the lower mold. A limit cover is installed on the front of the frame by bolts.

[0009] As a preferred technical solution, the driving mechanism includes an annular rail and a driving assembly. The annular rail is fixedly installed on the lower end of the fixed plate near the frame. A slip ring is slidably connected inside the annular rail, and a toothed ring is fixedly installed on the outer side of the slip ring. The driving assembly is fixedly installed at the lower end of the fixed plate, and the toothed ring and the driving assembly are meshed together. The frame is fixedly installed on the front side of the slip ring.

[0010] As a preferred technical solution, the drive assembly includes a fixed base, which is fixedly installed on the lower back of the fixed plate. A drive motor is fixedly installed on the back of the fixed base, and a gear is fixedly installed through the fixed plate at the output end of the drive motor. The gear and the gear ring are meshed together.

[0011] As a preferred technical solution, the demolding mechanism includes a guide block and a return spring. The return spring is fixedly installed on both ends of the inner side of the lower mold. A base plate is fixedly installed on the inner side of the return spring. A support shaft is fixedly installed on the outer side of the base plate. The end of the support shaft passes through the lower mold and is fixedly connected to a demolding template. The demolding template is slidably connected to the inside of the lower mold. The guide block is fixedly installed at the lower end of the fixed plate and is located in the middle of the annular rail and the slip ring. A guide plate is fixedly installed on the inner side of the demolding template. The guide plate at the bottom and the guide block are fitted together.

[0012] As a preferred technical solution, the overall lower end cross-sectional shape of the guide block is V-shaped, and the cross-sectional shape of the guide plate is an isosceles trapezoid.

[0013] As a preferred technical solution, the stamping mechanism includes a top plate, which is fixedly installed on the upper middle part of the front side of the fixed plate. A hydraulic cylinder is fixedly installed on the top of the top plate, and the hydraulic cylinder is fixedly installed on the front end of the top plate.

A servo motor for driving the conveyor belt is fixedly installed on one side of the front of the conveyor belt.

[0015] In summary, the present invention has the following main advantages:

[0016] First, the stamping mechanism and the drive mechanism in this device work together. When in use, starting the hydraulic cylinder can push the upper mold down and the lower mold to extrude and stamp the product. During processing, starting the drive motor drives the gear to rotate. Because the gear meshes with the gear ring, the slip ring rotates in the ring rail, thereby driving the frame and the lower mold to rotate and adjust. This allows the finished product to be moved out of the lower mold, and the unprocessed product to be moved to the bottom of the upper mold. Starting the hydraulic cylinder again can realize continuous production. This design greatly improves production efficiency, provides a guarantee for efficient production operations, and makes the device more flexible and efficient in the production process, meeting the needs of rapid production.

[0017] Secondly, the drive mechanism and demolding mechanism work together. When the drive motor is started, the gear and the ring gear are linked, driving the lower mold to reciprocate. When the lower mold reaches the bottom, the guide plate and the guide block are pressed together, pushing the support shaft to drive the demolding plate to slide and eject the product, achieving fast and stable demolding. After demolding, the frame rotates to separate the guide plate and the guide block. The reset spring drives the demolding plate to move down for reprocessing. This design can produce continuously and has strong demolding function, high stability, and high processing efficiency. The sliding of the support shaft and the lower mold improves stability, and the bolt-installed limit cover facilitates the inspection and replacement of the lower mold, improving production efficiency and providing convenience for stable operation and maintenance of the equipment.

Detailed Implementation

[0024] Example

[0025] refer to Figures 1 to 5 The metal product processing mold of this embodiment includes a frame 61. A fixing plate 5 is fixedly installed on the back of the frame 61. A stamping mechanism 3 is fixedly installed on the upper front of the fixing plate 5. A driving mechanism 2 is movably installed inside the frame 61 on the front of the fixing plate 5. An installation mechanism 6 is fixedly installed at the output end of the driving mechanism 2. Lower molds 4 are installed at equal intervals on the outer side of the installation mechanism 6. Demolding mechanisms 7 are fixedly installed on the inner side of the lower molds 4.

[0026] The mounting mechanism 6 includes a frame 61, which is fixedly mounted on the front of the drive mechanism 2. Mounting slots 62 are evenly spaced on the outer side of the frame 61. Slide plates 63 are slidably connected to both sides of the inner side of each mounting slot 62. The inner side of each slide plate 63 is fixedly connected to both sides of the lower mold 4. A limit cover 64 is bolted to the front of the frame 61. The frame 61, as the main body of the mounting mechanism 6, provides a stable mounting base for the lower mold 4, ensuring that the positions of each lower mold 4 are relatively fixed during processing, preventing significant shaking or displacement, thus guaranteeing processing accuracy. The evenly spaced mounting slots 62 on the outer side of the frame 61 provide sliding rails for the slide plates 63. The mounting mechanism 6 makes the installation and disassembly of the lower mold 4 more convenient and quick. The sliding plate 63 is fixedly connected to both sides of the lower mold 4. This design enhances the stability of the lower mold 4 during installation and facilitates the quick replacement of lower molds 4 of different specifications according to different processing needs. The limit cover 64 is installed by bolts, which not only ensures the safety of the lower mold 4 during use and prevents it from falling off accidentally, but also makes it easy to complete the operation by simply removing the bolts when the lower mold 4 needs to be inspected or replaced, which greatly improves the maintenance efficiency of the mold. Overall, the design of the mounting mechanism 6 makes the processing mold more flexible, efficient and easy to maintain during use.

[0027] refer to Figures 1-3 and Figure 5The drive mechanism 2 includes an annular rail 21 and a drive assembly 22.

A slip ring 24 is slidably connected inside the annular rail 21, and a toothed ring 23 is fixedly installed on the outer side of the slip ring 24. The drive assembly 22 is fixedly installed at the lower end of the fixed plate 5. The toothed ring 23 and the drive assembly 22 are meshed together. The frame 61 is fixedly installed on the front side of the slip ring 24. The drive assembly 22 includes a fixing seat 221, which is fixedly installed on the lower back side of the fixed plate 5. At the end of the fixed plate 5, a drive motor 222 is fixedly mounted on the back of the fixed base 221. A gear 223 is fixedly mounted through the output end of the drive motor 222, and a gear ring 23 is meshed with the gear 222. An annular rail 21 is fixed to the lower end of the fixed plate 5 near the frame 61, providing a stable sliding track for the slip ring 24. The slip ring 24 slides inside the annular rail 21, ensuring the smoothness and accuracy of the movement. The gear ring 23 on the outer side of the slip ring 24 meshes with the drive assembly 22, realizing efficient power transmission. The frame 61 is fixed to the front of the slip ring 24, so that the movement of the slip ring 24 can directly drive the frame 61 and the lower mold 4 mounted on the frame 61 to perform corresponding actions. The fixed seat 221 in the drive assembly 22 provides a solid mounting base for the drive motor 222, ensuring the stability of the motor during operation. As a power source, the drive motor 222 has a strong output capability and can accurately control the movement speed and direction of the slip ring 24. The output end of the drive motor 222 passes through the fixed plate 5 and is connected to the gear 223, which meshes with the gear ring 23. This design makes the power transmission more direct and reliable. Through the meshing transmission of the gear 223 and the gear ring 23, precise angle control and position adjustment can be achieved, ensuring that the lower mold 4 can be accurately moved to the required position for processing. At the same time, this transmission method has high efficiency and can quickly respond to various needs in the processing process, improving production efficiency. Overall, the design of the drive mechanism 2 makes the processing mold more accurate, efficient and stable during operation.

[0028] refer to Figures 4-5The demolding mechanism 7 includes a guide block 71 and a return spring 72. The return spring 72 is fixedly installed at both ends of the inner side of the lower mold 4. A base plate 73 is fixedly installed on the inner side of the return spring 72, and a support shaft 74 is fixedly installed on the outer side of the base plate 73. The end of the support shaft 74 passes through the lower mold 4 and is fixedly connected to a demolding template 75. The demolding template 75 is slidably connected to the inside of the lower mold 4. The guide block 71 is fixedly installed at the lower end of the fixed plate 5 and is located in the middle of the annular rail 21 and the slip ring 24. A guide plate 76 is fixedly installed on the inner side of the demolding template 75. The guide plate 76 at the bottom is in close contact with the guide block 71. The overall lower end cross-section of the guide block 71 is V-shaped, and the cross-section of the guide plate 76 is isosceles trapezoidal. The return spring 72 is fixedly installed at both ends of the inner side of the lower mold 4. After the demolding process is completed, the base plate 73, the support shaft 74, and the demolding template 75 can be quickly reset to prepare for the next processing, ensuring the continuity of processing. The base plate 73 provides a stable mounting foundation for the support shaft 74. The support shaft 74 can firmly connect the base plate 73 and the demolding template 75, so that the demolding template 75 can slide stably inside the lower mold 4 during the demolding process, accurately ejecting the molded product from the lower mold 4 and avoiding damage to the product during demolding. The guide block 71 is fixedly installed at the lower end of the fixed plate 5 and located in the middle of the annular rail 21 and the slip ring 24. Its overall lower end cross-section is V-shaped, which cooperates with the guide plate 76 with an isosceles trapezoidal cross-section fixedly installed inside the demolding template 75. When the mold moves to a specific position, the guide plate 76 and the guide block 71 at the bottom fit together. Through this inclined surface design, a precise guiding effect can be achieved during the mold movement. The mutual pressing of the guide block 71 and the guide plate 76 can effectively transmit power to the support shaft 74 and the demolding template 75, prompting the demolding template 75 to perform the demolding operation. This design not only improves the demolding efficiency, but also ensures the stability and accuracy of the demolding process, making the entire processing process more efficient and reliable.

[0029] refer to Figures 1-3The stamping mechanism 3 includes a top plate 31, which is fixedly installed on the upper center of the front of the fixed plate 5. A hydraulic cylinder 32 is fixedly installed on the top of the top plate 31, and the hydraulic cylinder 32 is fixedly installed on the front end of the top plate 31. The bottom output end of the hydraulic cylinder 32 passes through the top plate 31 and is fixedly installed with an upper die 33. An installation frame 8 is fixedly installed inside the lower end of the fixed base frame 1. A conveyor belt 9 is rotatably connected inside the installation frame 8. A servo motor for driving the conveyor belt 9 is fixedly installed on one side of the front of the conveyor belt 9. The top plate 31 is fixed on the upper center of the front of the fixed plate 5, providing a stable installation position for the hydraulic cylinder 32. As the power source for stamping, the hydraulic cylinder 32 has a strong thrust and can accurately control the downward pressing action of the upper die 33, ensuring that the force during the stamping process is uniform and stable, thereby ensuring the reliable quality of the processed metal products. Driven by the hydraulic cylinder 32, the stamping mechanism 33 can quickly cooperate with the lower mold 4 for stamping and forming, improving production efficiency. The mounting bracket 8 at the lower end of the fixed base frame 1 provides support for the conveyor belt 9. Driven by the servo motor, the conveyor belt 9 can run smoothly. During the processing, the conveyor belt 9 can promptly transport the processed products out, avoiding product accumulation that affects subsequent processing and improving the continuity of production. The servo motor has high-precision control performance and can adjust the speed of the conveyor belt 9 according to actual needs to ensure that the products can be accurately transported to the designated position. At the same time, it can also quickly respond to stop or start commands when needed, providing strong support for the automated control of the entire processing process. This cooperative design of the stamping mechanism 3 and the conveyor belt 9 makes the processing of metal products more efficient, stable, and highly automated.

[0030] Operating principle and advantages: By setting the stamping mechanism 3 and the drive mechanism 2 to cooperate with each other, when the device is put into use, the hydraulic cylinder 32 can be started. Once the hydraulic cylinder 32 starts working, it will forcefully push the upper mold 33 downward. As the upper mold 33 moves downward, the upper mold 33 and the lower mold 4 squeeze each other, thereby quickly stamping and forming the product. During the processing, by starting the drive motor 222, the gear 223 is driven to rotate. Since the gear 223 and the gear ring 23 are in a meshing connection, the gear ring 23 will drive the slip ring 24 to rotate inside the annular rail 21. The rotation of the moving slip ring 24 can drive the frame 61 to rotate accordingly. By adjusting the rotation angle of the frame 61, the lower molds 4 on the frame 61 can be rotated and adjusted. When the lower molds 4 are rotated and adjusted, the lower molds 4 containing the finished products that have been processed and are waiting to be used can be moved out, while the lower molds 4 that have not yet been processed will be moved back to the bottom of the upper mold 33. At this time, the hydraulic cylinder 32 is driven again to run, so that continuous and uninterrupted rapid production processing can be carried out. This design greatly improves the overall production processing efficiency of the device and provides a strong guarantee for efficient production operations.

[0031] By setting the drive mechanism 2 and the demolding mechanism 7 to cooperate with each other, during use, when the device is in use, the drive motor 222 can be started to drive the gear 223 and the gear ring 23 to move in tandem. In this way, the various lower molds 4 inside the frame 61 can be driven to reciprocate synchronously. When the lower mold 4 moves to the bottom position, the guide plate 76 and the guide block 71 on the inner side of the lower mold 4 press against each other. The inclined surfaces of the guide plate 76 and the guide block 71 press against each other and play a guiding role. At this time, the guide plate 76 pushes the support shaft 74, which in turn drives the extrusion demolding plate 75 to slide inside the lower mold 4. In this way, the product formed inside the lower mold 4 can be ejected from the inside of the lower mold 4, so that the whole device can quickly and stably push the product to demold. After demolding is completed, as the frame 61 rotates, the guide block 71 and the guide block 75 move in tandem. When plates 76 are misaligned and separated, the return spring 72 resets, causing the demolding plate 75 to move downwards. This allows for reprocessing. This design enables continuous, uninterrupted production and provides a strong and stable demolding function, resulting in greater stability and higher processing efficiency during overall production. It is indeed worthwhile to use this equipment. Furthermore, the sliding fit between the support shaft 74 and the lower mold 4 significantly improves the stability of the support shaft 74 in driving the demolding plate 75. The bolt-mounted limit cover 64 allows for easy disassembly and maintenance of the lower mold 4 and demolding mechanism 7 when maintenance or replacement is required; simply remove the bolts to remove the limit cover 64. This greatly improves the overall production efficiency of the equipment and facilitates stable operation and maintenance.
