Description

Technical Field

[0001] This utility model relates to the technical field of stamping dies, and in particular to a wedge ejection mechanism for stamping dies. Background Technology

[0002] Stamping dies are a pressure processing method in which a die mounted on a press is used to apply pressure to the material during cold stamping, causing it to separate or plastically deform, thereby obtaining the desired part. Stamping dies can be divided into two types: engineering dies and progressive dies.

[0003] After a stamping process is completed, the stamped product needs to be separated from the mold. Some existing molds use stripper plates for stripping, which is complex, ineffective, and affects the continuity of stamping. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a wedge ejector mechanism for stamping dies. This mechanism can conveniently and quickly eject stamped products, ensuring the continuity of stamping operations and bringing great convenience to production and use.

[0005] To solve the above-mentioned technical problems, the present invention adopts a wedge ejection mechanism for a stamping die, comprising: a stamping assembly disposed on an upper die plate, a pusher head, an ejection fixing seat disposed on a lower die plate, and a positioning block disposed on the side of the ejection fixing seat. The stamping assembly includes a first punch and a second punch symmetrically disposed with respect to the first punch. A first cavity and a second cavity are disposed parallel to each other in the ejection fixing seat. A wedge pusher block is slidably disposed in the first cavity. A nitrogen cylinder is disposed in the second cavity, and the output end of the nitrogen cylinder is connected to the wedge pusher block to form a linkage integral structure. Both ends of the wedge pusher block extend from the first cavity, and one end is used to place the product to be stamped. When the die is closed, the other end of the wedge pusher block abuts against the pusher head.

[0006] In a preferred embodiment of this utility model, when the mold is closed, the upper mold plate drives the first punch and the second punch to press down, bending the two wings of the product to be stamped on one end of the wedge pusher.

[0007] In a preferred embodiment of this utility model, the rear halves of the first cavity and the second cavity are connected, and the output end of the nitrogen cylinder is connected to the wedge pusher block by bolts.

[0008] In a preferred embodiment of the present invention, the nitrogen cylinder is locked in the second cavity by fasteners.

[0009] In a preferred embodiment of the present invention, the surface of the inclined wedge pusher is provided with a plurality of oil injection holes, and the oil injection holes are of an "X" shape.

[0010] In a preferred embodiment of the present invention, a limiting waist hole is provided on the upper surface of the material stripping fixing seat, and a limiting post is provided on the inclined wedge push block to move back and forth within the limiting waist hole.

[0011] The beneficial effects of this utility model are: the upper template drives the first punch and the second punch to press down, which bends and resets the two wings of the product to be stamped on one end of the wedge pusher. The nitrogen cylinder drives the wedge pusher to move towards the inside of the first cavity, thereby separating the stamped product from the wedge pusher. This allows for convenient and quick unloading of the stamped product, ensuring the continuity of the stamping operation and bringing great convenience to production and use.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1-3This utility model discloses a wedge ejector mechanism for a stamping die, comprising: a stamping assembly disposed on an upper template, a pusher head 1, an ejector fixing seat 2 disposed on a lower template, and a positioning block 3 disposed on the side of the ejector fixing seat. The stamping assembly includes a first punch 4 and a second punch 5 symmetrically disposed with respect to the first punch. A first cavity 6 and a second cavity 7 are arranged in parallel within the ejector fixing seat. A wedge pusher block 8 is slidably disposed within the first cavity, and a nitrogen cylinder 9 is disposed within the second cavity. The rear halves of the first cavity and the second cavity are connected. The output end of the nitrogen cylinder is connected to the wedge pusher block by bolts to form a linkage integral structure. The nitrogen cylinder is locked within the second cavity by fasteners. Both ends of the wedge pusher block extend from the first cavity, with one end used to place the product to be stamped and the other end of the wedge pusher block abutting against the pusher head.

[0018] The stamping process during mold closing is as follows: When the mold closes, the upper mold mechanism moves downward, and the upper template drives the first punch and the second punch to press down and bend the two wings of the product 10 to be stamped on one end of the wedge pusher. At this time, the pusher head cooperates with the positioning block and abuts against the other end of the wedge pusher, playing an auxiliary positioning role. After stamping is completed, the upper mold mechanism moves upward, and the first punch and the second punch separate from the stamped product. At this time, the nitrogen cylinder drives the wedge pusher to move towards the inside of the first cavity, thereby removing the stamped product from one end of the wedge pusher. This allows for convenient and quick stripping of the stamped product, ensuring the continuity of the stamping operation and resulting in a good stripping effect of the stamping mold.

[0019] Specifically, several oil injection holes 11 are provided on the surface of the wedge pusher. The oil injection holes have an "X" shaped structure. Operators can add lubricating oil into the oil injection holes to ensure smooth sliding of the wedge pusher in the first cavity.

[0020] Specifically, the upper surface of the material removal fixing seat is provided with a limiting waist hole 12, and the inclined wedge push block is provided with a limiting post 13 that moves back and forth in the limiting waist hole. The left and right movement of the inclined wedge push block driven by the nitrogen cylinder in the first cavity is constrained by the limiting waist hole.

[0021] The beneficial effects of this utility model are: the upper template drives the first punch and the second punch to press down, which bends and resets the two wings of the product to be stamped on one end of the wedge pusher. The nitrogen cylinder drives the wedge pusher to move towards the inside of the first cavity, thereby separating the stamped product from the wedge pusher. This allows for convenient and quick unloading of the stamped product, ensuring the continuity of the stamping operation and bringing great convenience to production and use.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
