[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a stamping machine for processing mold parts, including a frame 1. The frame 1 serves as the supporting structure for the entire stamping machine, providing a stable mounting base for other components. Its strength and stability ensure that the stamping machine will not shake or deform during long-term, high-intensity operation, thereby ensuring processing accuracy. A base plate 2 is fixedly connected to the top of the frame 1, and the base plate 2 is tightly connected to the frame 1, providing a stable mounting platform for components such as the lower mold 3 and support columns 4. The lower mold 3 is fixedly connected directly above the base plate 2. The lower mold 3 is a key component for forming mold parts. Its shape and size are designed according to the mold parts to be processed, enabling precise stamping and forming of the parts. Four support columns 4 are fixedly connected to the base plate 2, and the four support columns 4 are distributed in a square shape. The support columns 4 ensure that the entire structure is evenly stressed, effectively supporting the top plate 5 above and related stamping components, ensuring the stability of the entire structure during the stamping process. The top plate 5 is fixedly connected between the tops of the four support columns 4. Plate 5 provides an installation position for hydraulic cylinder 6 and air blowing assembly, and also bears the downward pressure generated by hydraulic cylinder 6 during operation. Hydraulic cylinder 6 is fixedly connected to the top center of top plate 5. Upper mold 7 is fixedly connected to the output end of hydraulic cylinder 6. As a power source, hydraulic cylinder 6 can generate strong and stable thrust. Upper mold 7 is fixedly connected to its output end. Through the extension and retraction of hydraulic cylinder 6, upper mold 7 is driven to move up and down, thereby realizing the stamping action of mold parts. Connecting rods 10 are fixedly connected to the left and right sides of the bottom of upper mold 7. Under the action of transmission assembly, connecting rods 10 convert the up and down movement of upper mold 7 into a specific movement form to ensure the smooth progress of stamping action. Transmission assembly is installed inside frame 1. Transmission assembly can convert the linear movement of hydraulic cylinder 6 into the movement of lifting assembly. Air blowing assembly is installed on the upper side of top plate 5. Air blowing assembly can blow air on mold and parts during or after stamping to remove debris and other impurities generated during processing, ensuring the cleanliness of mold and parts and improving processing quality.

[0033] Reference Figure 3The transmission assembly includes two mounting plates 11, which provide a stable mounting base for components such as the turntable 12 and the disc 16, ensuring the relative positional accuracy of these components during operation. The mounting plates 11 are fixedly connected inside the frame 1. The turntable 12 is rotatably connected to one side of the mounting plates 11, allowing it to rotate around its axis during operation, providing rotational power for the entire transmission process. An eccentric shaft 13 is fixedly connected to the edge of the turntable 12 furthest from the mounting plates 11, enabling it to generate circular motion during rotation. A limit block 14 is fixedly connected to the side of the eccentric shaft 13 furthest from the turntable 12. The movement range of the eccentric shaft 13 in the sliding connection component can be limited to prevent excessive displacement or disengagement during operation, thus ensuring the stability of the transmission. The eccentric shaft 13 is externally slidably connected to a rotating frame 15. The rotating frame 15 performs specific movements under the drive of the eccentric shaft 13 and rotates under the stamping of the upper mold 7 through the connection with the connecting rod 10. The bottom of the connecting rod 10 is fixedly connected to the top of the rotating frame 15. A lifting component is installed on the side of the mounting plate 11 away from the turntable 12. The lifting component plays an auxiliary role in the entire stamping process, lifting the mold parts or the upper mold 7 after stamping to facilitate subsequent operations.

[0034] Reference Figure 3 and Figure 4 The lifting assembly includes a disc 16, which serves as a key rotating component. Its rotation drives the movement of a slider 17. The disc 16 is rotatably connected to the side of the mounting plate 11 away from the turntable 12. A slider 17 is fixedly connected to the edge of the disc 16 away from the turntable 12. The slider 17 moves along a specific track as the disc 16 rotates. A mounting bracket 18 is installed between the tops of the two sliders 17. The mounting bracket 18 can move up and down under the influence of the sliders 17, thus achieving the lifting function. Two grooves 19 are formed along the length of the bottom of the mounting bracket 18. In conjunction with the slider 17, the slider 17 can accurately drive the mounting frame 18 to move during rotation, ensuring the smoothness and directionality of the movement. Multiple push rods 20 are installed on the top of the mounting frame 18 along the length direction. The multiple push rods 20 can evenly distribute the lifting force, ensuring that the mold parts or related components are subjected to uniform force during the lifting process, avoiding damage to the components or a decrease in processing accuracy due to uneven force. A push block 21 is fixedly connected to the upper side of the push rod 20. The push block 21 can increase the contact area with the lifted part, further optimize the lifting effect, and at the same time protect the surface of the push rod 20 and the lifted part.

[0035] Reference Figure 5The air blowing assembly includes a cylinder 25, which serves as the main structure of the air blowing assembly. The cylinder 25 houses components such as a piston 26, providing space for gas storage and flow. The cylinder 25 is located on top of the top plate 5. The piston 26 is slidably connected inside the cylinder 25 and can slide up and down within the cylinder 25. Its movement changes the gas pressure inside the cylinder 25. Two one-way valves 27 are fixedly connected to the top of the cylinder 25. The one-way valves 27 can control the flow direction of the gas, ensuring that the gas can only flow in a predetermined direction and guaranteeing the normal operation of the air blowing. One of the one-way valves 27 is fixedly connected to a pipe 24, which transports the gas inside the cylinder 25 to the position where air blowing is required. A connecting rod 22 is fixedly connected to the bottom of the piston 26. The connecting rod 22 transmits the movement of the upper mold 7 to the piston 26, so that the movement of the piston 26 is synchronized with the stamping action of the upper mold 7, thereby performing the air blowing operation at the appropriate time.

[0036] Reference Figure 1 Four sliding rods 8 are installed on the upper side of the lower mold 3. The sliding rods 8 provide guidance for the up and down movement of the upper mold 7, ensuring that the upper mold 7 can accurately cooperate with the lower mold 3 during the stamping process, thereby improving the stamping accuracy. Four sliding sleeves 9 are installed at the bottom of the upper mold 7. The sliding sleeves 9 cooperate with the sliding rods 8 to reduce the friction of the upper mold 7 during the movement, and at the same time further ensure the linearity of the movement, preventing the upper mold 7 from deviating during the stamping process and affecting the processing quality of the mold parts. The sliding rods 8 are internally slidably connected to the outside of the sliding sleeves 9. The sliding connection method allows the upper mold 7 to move smoothly up and down under the guidance of the sliding rods 8.

[0037] Reference Figures 2-4 The top protruding part of the ejector rod 20 is slidably connected to the inside of the lower mold 3. The sliding connection allows the ejector rod 20 to accurately act on the mold parts or related components inside the lower mold 3 during the lifting process, achieving a smooth lifting operation. At the same time, it can also avoid interference between the ejector rod 20 and the lower mold 3. The outer side of the connecting rod 10 is slidably connected to the inside of the base plate 2. During the movement, the connecting rod 10 ensures the stability and accuracy of its movement through the sliding connection with the base plate 2, further ensuring that the stamping action of the upper mold 7 can be carried out according to the predetermined trajectory.

[0038] Reference Figure 1 The end of the connecting rod 22 away from the piston 26 is fixedly connected to the top edge of the upper mold 7, so that the upper mold 7 can directly drive the connecting rod 22 to move during the up and down movement, thereby making the piston 26 move synchronously in the cylinder 25, realizing the close coordination between the air blowing operation and the stamping action, and cleaning the impurities on the surface of the mold and parts in a timely manner during or after stamping.

[0039] Reference Figure 1An air blowing plate 23 is fixedly connected to the top edge of the base plate 2. The air blowing plate 23 can evenly disperse the gas delivered from the pipe 24, increase the coverage area of ​​the air blowing, and more effectively remove debris and other impurities around the mold and parts. The end of the pipe 24 away from the one-way valve 27 is fixedly connected to the inside of the air blowing plate 23 to ensure that the gas can be smoothly delivered from the cylinder 25 through the pipe 24 to the air blowing plate 23, and play a role in air blowing and cleaning at the air blowing plate 23.

[0040] Reference Figure 1 The connecting rod 22 is slidably connected to the inside of the top plate 5 on the outside. The sliding connection method allows the connecting rod 22 to remain stable when it follows the movement of the upper mold 7, while reducing friction with the top plate 5, ensuring that the movement of the connecting rod 22 is not hindered, thereby ensuring the normal operation of the air blowing assembly.

[0041] Working principle: When stamping mold parts is required, the mold is placed inside the lower mold 3. Then, the hydraulic cylinder 6 is activated, causing it to slide, which in turn pushes the upper mold 7 to slide and inject the part. After injection molding, the hydraulic cylinder 6 is raised. When the hydraulic cylinder 6 rises and slides, it drives the connecting rod 10 to slide. The sliding of the connecting rod 10 drives the rotating frame 15 to slide, further driving the eccentric shaft 13 to rotate, causing the turntable 12 to rotate. The rotation of the turntable 12 drives the disk 16 to rotate, which in turn drives the slider 17 to rotate. The slider 17 is... Sliding inside the slide groove 19, the rotation of the slider 17 causes the mounting bracket 18 to slide up and down, which in turn causes the ejector rod 20 to slide, ejecting the molded part. While the upper mold 7 is sliding, the connecting rod 22 is also sliding. The sliding of the connecting rod 22 causes the piston 26 to slide, which changes the air pressure inside the one-way valve 27. When the piston 26 slides downward, the air pressure at the top of the cylinder 25 will enter through the one-way valve 27, which is not connected to the pipe 24. When the piston 26 slides upward, the air is exhausted through the one-way valve 27 connected to the pipe 24 and discharged through the air blowing plate 23 to clean the lower mold 3.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
