[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 4The present invention provides an embodiment of a novel injection molding mold, comprising a box 1. Box 1 is the main body of the mold, typically a closed box structure, used to mount and support various other components. Cylinder 1 is fixedly connected to the interior of box 1. Cylinder 1 is the mold's power source, responsible for providing pressure or force to drive the mold's movement. A fixed plate 3 is fixedly connected to the output end of cylinder 1. Two fixed blocks 4 are fixedly connected to the top of fixed plate 3, which support the lifting assembly. Sliders 5 are slidably connected to the interior of the fixed blocks 4, which secure and support the subsequent slide 5 assembly. The tops of the two slides 5 are fixedly connected to stripper plates 6. Sliders 5 are linear guide components in the mold, used to control the mold's vertical movement. Stripper plates 6 are used to secure the upper structure of the mold for demolding operations. A support platform 7 is fixedly connected to the exterior of cylinder 1, providing additional support and stability during mold operation. Two fixing bolts 8 are fixedly connected to the left and right sides of support platform 7, respectively, which typically secure and support a rotating rod 9. The exterior of the fixing bolt 8 is fixedly connected to a rotating rod 9, which is used to connect the mold components. The exteriors of the two rotating rods 9 are each rotatably connected to a connecting rod 10, which is cross-connected by bolts. Connecting rods 10 are used to enhance the stability and strength of the connection between the mold components. The exteriors of the two connecting rods 10 are each rotatably connected to a connecting rod 11, which provides connection and support during mold operation. The exteriors of the multiple connecting rods 11 are rotatably connected to two fixing bars 12, which are typically used to secure and support the top structure of the mold.

[0032] Reference Figure 1 、 Figure 2 The top four corners of the box 1 are fixedly connected with support columns 13, which are used to support and stabilize the entire mold structure. The top of the box 1 is fixedly connected with a mold stamping assembly, and the top of the box 1 is fixedly connected with a buffer assembly to prevent mold damage.

[0033] Reference Figure 2 The stamping assembly includes a top plate 14, which is used to support and fix the various components during the stamping process. The bottom end of the top plate 14 is fixedly connected to a cylinder 2 15, which is used to provide additional pressure or power to push the die plate 16 to perform the stamping action. The output end of the cylinder 2 15 is fixedly connected to the die plate 16. The die plate is an important dynamic component in the mold, which is used to apply pressure and shape stamping on the workpiece during the stamping process. The bottom end of the die plate 16 is fixedly connected to a cover plate 17, which is used to fix the bottom structure of the die plate 16 when the mold is running and provide additional support and stability. The bottom end of the die plate 16 is fixedly connected to a plurality of bosses 18, which are components used to fix and support the positioning and fixing of the workpiece on the die plate 16.

[0034] Reference Figure 3 The buffer assembly includes a mold box 19, which is used to accommodate and fix the die plate 16 or other stamping parts. An inner cavity 20 is provided inside the mold box 19, and slide grooves 21 are provided inside the four corners of the top of the mold box 19. The function of the slide grooves 21 is to accommodate and enable the limit plate 22 to slide therein. The internal sliding connection of the slide groove 21 is provided with a limit plate 22. The main function of the limit plate 22 is to limit the range of motion of the die plate 16 or other movable parts to ensure that they move or stay in the correct position. The bottom end of the limit plate 22 is fixedly connected to a spring 23. The function of the spring is to provide a certain amount of elastic support and pressure so that the limit plate 22 can remain stable during movement and is not easily affected by external vibrations or impacts.

[0035] Reference Figure 2 、 Figure 3 、 Figure 4 The top ends of the two fixing bars 12 are fixedly connected to the bottom end of the stripper plate 6. The fixing bars 12 are typically used to secure and support the structural elements of the stripper plate 6, ensuring that the stripper plate 6 can move stably or remain in a fixed position during the stamping process. The outer ends of the two sliding columns 5 are slidably connected to the inner wall of the fixing plate 3. The sliding columns 5 are used to maintain the fixed plate 3 and other moving parts to ensure precise movement and stability during the stamping process. The outer end of the stripper plate 6 is slidably connected to the outside of the inner cavity 20. The stripper plate 6 is a moving part in the mold and is used to remove the finished product from the mold after the stamping is completed. The bottom end of the cylinder 12 is fixedly connected to the inner wall of the bottom end of the square box 1. The cylinder 12 is a pneumatic component used to provide power in the mold and is typically used to control the up and down movement of the pressing plate 16 or other moving parts. The bottom end of the top plate 14 is fixedly connected to multiple support columns 13. The support columns 13 support columns 13 function to support and stabilize the position of the top plate 14 in the mold structure, ensuring that the top plate 14 can withstand the forces during the stamping process without deformation or movement. The bottom end of the mold box 19 is fixedly connected to the top end of the box 1. As part of the mold, the mold box 19 typically houses the die plate 16 or other important components, providing necessary support and fixation. The top end of a spring 23 is fixedly connected to the bottom end of a limit plate 22. The outer portion of the limit plate 22 is slidably connected to the inner wall of the mold box 19. The spring 23 provides the elastic support required by the limit plate 22, which, in turn, limits the movement of the die plate 16 or other moving components by slidingly connecting to the inner wall of the mold box 19.

[0036] Working principle: During use, first pour the plastic into the mold box 19, and then start the second cylinder 15. The second cylinder 15 pushes the cover plate 17 downward, and the cover plate 17 moves downward with the cover plate 17 and the boss 18, so that the pressing plate 16 contacts the mold box 19, and the boss 18 contacts the limit plate 22 and pushes the limit plate 22 to slide downward. The limit plate 22 compresses the slide 21, so that the pressure of the pressing plate 16 on the mold box 19 is reduced when the pressing plate 16 contacts the mold box 19, preventing damage to the mold box 19, reducing the vibration intensity of the mold, reducing the damage to the mold caused by vibration, and thus extending the service life of the mold.

[0037] After the plastic is stamped and formed, cylinder 1 (2) is activated, driving fixed plate 3 upward. This in turn drives fixed bolt 8 upward, which in turn drives connecting rod 10 upward. Connecting rod 10 rotates on fixed bolt 8, driving rotating rod 9 and connecting rod 11. This causes fixed bar 12 to push fixed bar 12 upward, which in turn drives stripper plate 6 upward, pushing the molded product out of mold box 19 and automatically removing it. Automatic extrusion molds can quickly and accurately remove finished products from the mold, reducing manual operation time and significantly improving production efficiency. Compared to manual operation, automated systems can complete mold removal more quickly, shortening the cycle time for each cycle.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
