[0002] In recent years, with the increasingly fierce competition in the automobile market, major automobile manufacturers have turned their attention to the automobile's own covers and related stamping parts (hereinafter collectively referred to as parts) in the direction of developing and researching new models. The requirements for them are getting higher and higher, and the parts tend to be more complex and high-strength. Major mold manufacturers are also facing this technical problem. According to these characteristics of the parts, the process personnel design and layout the process procedures, formulate the process documents of this part, and determine the size of the mold and the number of process steps for producing this part.

[0036] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0037] like Figure 1-Figure 2 As shown, this embodiment discloses a tail product stripping mechanism, which is used in the stripping process of mold processing, and its structure includes a molding module and a stripping module;

[0038] The forming module includes an upper die base 1, a cutting knife 2, a stripping plate 3, a window plate 4, a side plate 10, a lower die plate 11 and a lower die base 12, which are used to realize the pressing and forming of the workpiece 8;

[0039] The stripping module comprises a fixed seat 5, a rotating hook 6, a floating seat 7 and a floating material support 9, which is used for automatically stripping the workpiece 8 after it is pressed and formed.

[0040] like Figure 1 As shown, the specific structure of the molding die includes:

[0041] The stripping plate 3 is located below the upper die base 1 and is arranged parallel to the upper die base 1, and the bottom wall of the upper die base 1 is connected with a cutting knife 2 that penetrates the stripping plate 3, and the cutting knife 2 is connected to the stripping plate 3. The connection method of the cutting knife 2 and the stripping plate 3 includes:

[0042] The cutting blade 2 is fixedly connected to the stripping plate 3; or,

[0043] The cutting knife 2 is provided with a step groove, and the stripping plate 3 is overlapped on the step groove, which can improve the freedom of movement of the two and facilitate adaptation to workpieces 8 of different thicknesses.

[0044] The lower end of the stripper plate 3 is fixedly connected to a window plate 4 , a lower mold plate 11 is provided below the window plate 4 , the workpiece 8 is placed between the window plate 4 and the lower mold plate 11 , and is pressed under the movement of the upper mold base 1 .

[0045] like Figure 1 As shown, the lower template 11 is fixed on the lower mold base 12, and the lower mold base 12 is also connected with a side plate 10 which is parallel to the lower template 11 and is used to prevent the cutting knife 2 from deviating. That is, the gap between the lower template 11 and the side plate 10 is infinitely close to the width of the cutting knife 2.

[0046] In this embodiment, a wear-resistant plate corresponding to the cutting knife 2 is also provided on the side protection plate 10 .

[0047] like Figure 1 and Figure 2 As shown, the specific structure of the stripping module includes:

[0048] The fixed seat 5 is fixed on the stripping plate 3 and close to one side of the workpiece 8. The fixed seat 5 is rotatably connected with a rotating hook 6 through a latch. Figure 2 As shown, the rotation range of the swivel hook 6 is between 0° and 90° (or between -90° and 0°).

[0049] During the pressing process, the workpiece 8 is always placed within the rotation range of the rotating hook 6.

[0050] When the workpiece 8 contacts the rotating hook 6, the rotating hook can rotate around the latch to adapt to the shape of the workpiece 8 and changes during the stamping process.

[0051] The floating seat 7 is connected to the lower die seat 12 in a floating manner through a floating spring 701 , and a horizontally arranged floating material support 9 for supporting the workpiece 8 is also arranged on the floating seat 7 . The floating arrangement can adapt to the movement changes of the workpiece 8 during processing.

[0052] In this embodiment, the whole working process includes four stages:

[0053] The first stage: At the beginning, the upper die base 1 is at the top dead center of the machine tool, and the lower die base 12 is on the working table of the punch press. When the punch press is working, the upper die base 1 and all the components connected to it (including the stripper plate 3, the fixed base 5, the rotating hook 6, etc.) start to move downward until the rotating hook 6 contacts the workpiece 8.

[0054] The second stage: the upper die base 1 continues to move downward, and the rotating hook 6 rotates around the latch due to the force of the workpiece 8. When the rotating hook 6 continues to move downward with the upper die base 1, the highest point of the rotating hook 6 exceeds the workpiece 8, and the rotating hook 6 is reset due to gravity.

[0055] The third stage: the upper die seat 1 continues to move downward, the window plate 4 presses the workpiece 8 and the floating material support 9 continues to move downward until the bottom dead point of the machine tool, at which time the cutting knife 2 completes its work.

[0056] The fourth stage: the punch press starts to move upward, the upper die seat 1 moves upward with it, and the stripper plate 3 moves upward with it. The rotating hook 6 hooks the workpiece 8 while following the stripper plate 3 upward, and moves the workpiece 8 upward. Since the workpiece 8 is only subjected to force on one side, it slides outwards, completing the stripping of the workpiece 8. The upper die seat 1 returns to the top dead center, and the cutting process is completed.

[0057] During the whole process, the tail product stripping mechanism composed of the fixed seat 5, the latch and the rotating hook 6 plays a key role. It has a simple structure and an excellent stripping effect, which reduces the processing difficulty of the mold, reduces the mold space, and ensures the production efficiency of the continuous mold.

[0058] The beneficial effects of this embodiment include:

[0059] Improved production efficiency:

[0060] Through precise die design and close fit between components, stamping progressive dies can achieve an efficient and continuous production process.

[0061] The high degree of automation reduces manual intervention and operation time, thereby improving production efficiency.

[0062] Ensure the quality of parts:

[0063] The precise design and manufacture of the mold ensures high precision and consistency of the parts.

[0064] The fine coordination of components such as the rotating hook and window plate enables the parts to be accurately positioned and supported during the stamping process, thus ensuring the quality of the parts.

[0065] Reduce production costs:

[0066] Large-scale use of molds for production can reduce the production cost of a single part.

[0067] The high durability and long life of the molds reduce the need for frequent replacement and repairs, further reducing production costs.

[0068] In summary, through the precise connection relationship and the beneficial effects of each component, an efficient, accurate and safe production process is achieved, bringing significant benefits to industrial production.

[0069] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
