Description

Technical Field

[0001] This utility model relates to the field of trimming and waste material removal molds. More specifically, this utility model relates to a segmented trimming and waste material removal mold structure. Background Technology

[0002] With the development of automation in the automotive industry, stamping dies play an increasingly important role in automobile production, and their production efficiency and stability are receiving high attention. However, the traditional trimming and scrap-discharging structure of stamping dies has significant shortcomings when dealing with parts made of materials with high hardness. For example, conventional ring-shaped trimming dies typically cut scrap into two sections, a structure prone to jamming problems in actual production. When the scrap is long, it may deviate from its intended trajectory during discharge due to vibration or friction, causing it to become obliquely stuck in the scrap channel. This jamming phenomenon not only frequently interrupts production, increases the workload of manual cleaning, and reduces production efficiency, but may also damage the die cutting edge, increasing die maintenance costs.

[0011] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the segmented trimming and waste material removal mold structure in this utility model. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0015] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0016] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0017] like Figure 1 As shown, a preferred embodiment of this utility model provides a segmented trimming and waste material removal mold structure, including an upper template 1, a trimming die 2, an outer guide post 3, a trimming punch 4, a cutting blade 10, and a lower mold base 11; wherein,

[0018] The upper template 1 and the lower mold base 11 are arranged vertically and vertically respectively. The trimming die 2 is installed on the lower surface of the upper template 1. The lower mold base 11 has an opening in the middle. The trimming punch 4 is installed on the lower mold base 11 and is arranged around the opening of the lower mold base. The part 8 is embedded in the opening of the lower mold base 11. Several cutting blades 10 are evenly distributed around the trimming punch 4. The upper template 1 moves downward under the drive of the press, thereby driving the trimming die 2 to move downward, so that the trimming punch 4 is embedded in the matching trimming die 2.

[0019] In the above technical solution, at the start of stamping, the upper die plate 1 connected to the press drives the trimming die 2 to move downwards. When the trimming die 2 contacts the part 8, it trims the part 8 under the combined action of the trimming punch 4, generating a complete ring of scrap material. As the scrap material 9 accumulates to a certain extent, it is squeezed against the cutting blade 10, which cuts the entire ring of scrap material into 4 pieces through the reaction force. Subsequently, under the action of gravity, this scrap material moves through the mold cavity to the inclined guide plate and slides out of the mold along the guide plate, completing the scrap material discharge. After stamping is completed, the press drives the upper die plate to move upwards to reset, waiting for the next stamping operation. The entire process efficiently completes the trimming operation of the part and effectively handles the scrap material, ensuring the smooth progress of the production process and the stability of product quality.

[0020] In a preferred embodiment of this utility model, the mold structure further includes an inner guide post 5, which is installed on the lower mold base 11. An inner sleeve 13 is installed at the bottom of the upper mold plate 1. As the upper mold plate 1 moves downward, the inner guide post 5 can be inserted into the inner sleeve 13.

[0021] In the above technical solution, the addition of inner guide pillars and inner sleeves further improves the guiding accuracy and stability of the mold. During the downward movement of the upper mold plate, the inner guide pillars can accurately insert into the inner sleeves, ensuring smoother and more accurate relative movement between the various components of the mold. This effectively avoids trimming quality problems and mold damage risks caused by inaccurate guidance, thereby further improving production efficiency and mold lifespan, and enhancing the reliability and stability of the mold.

[0022] In a preferred embodiment of this utility model, the mold structure further includes an outer guide post 3, which is disposed at the bottom of the upper mold plate 1, and an outer guide sleeve 7 is disposed on the lower mold base 11. As the upper mold plate 1 moves downward, the outer guide post 3 can be inserted into the outer sleeve 7.

[0023] In the above technical solution, the guiding system of the mold is further optimized by setting external guide pillars and external guide sleeves. The cooperation between the external guide pillars and external guide sleeves provides a more stable and reliable guiding effect for the mold, ensuring that the upper mold plate maintains an accurate movement trajectory during downward movement, thereby improving the processing accuracy and stability of the mold. This guiding method of external guide pillars and external guide sleeves has a simple structure, is easy to implement, and can effectively adapt to the processing needs of parts of different sizes and shapes, further enhancing the versatility and practicality of the mold, and improving production efficiency and product quality.

[0024] In a preferred embodiment of this utility model, the mold structure further includes limiting posts 6. Several of these posts are respectively disposed on the lower mold base 11 and located outside the trimming punch 4.

[0025] In the above technical solution, the use of locating posts provides an effective limiting function for the mold. The locating posts restrict the stroke of the upper mold plate and the trimming die during downward movement, preventing excessive downward pressure that could damage mold components or affect processing quality. Simultaneously, the locating posts ensure that the trimming punch maintains a stable position and movement during operation, avoiding processing errors caused by excessive movement. This limiting measure is simple and practical, effectively improving the safety and reliability of the mold, extending its service life, and ensuring stable production.

[0026] In a preferred embodiment of the present invention, the mold structure further includes a guide plate 12, which is located below the opening of the lower mold base 11, and the guide plate is inclined.

[0027] In the above technical solution, the inclined guide plate effectively improves the efficiency and smoothness of waste discharge. The inclined guide plate provides a sloping channel for the waste, allowing it to be discharged more smoothly from the mold under gravity, preventing waste accumulation inside the mold. This design not only improves the mold's production efficiency and reduces downtime for cleaning due to waste accumulation, but also effectively protects mold components from damage caused by waste buildup, extending the mold's service life. Furthermore, it helps ensure the processing quality of parts and improves production stability and reliability.

[0028] In a preferred embodiment of this utility model, the cutting blade 10 of the mold structure is L-shaped, with its horizontal section fixed on the lower mold base 11 and its vertical section close to the side of the lower mold base.

[0029] In the above technical solution, the cutting blade is designed in an L-shape, and its horizontal section is fixed to the lower die base, which effectively improves the stability and cutting effect of the cutting blade. The structural characteristics of the L-shaped cutting blade allow it to better withstand shearing forces during the cutting process, while the fixing method of the horizontal section ensures that the cutting blade maintains a stable position and posture during operation, avoiding loosening or damage caused by cutting forces. This design not only improves the cutting quality of waste materials but also extends the service life of the cutting blade, reduces die maintenance costs, and further improves the production efficiency and reliability of the die, meeting the requirements of modern industrial production for efficient and stable die operation.

[0030] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
