Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a continuous die-cutting mold. Background Art

[0002] The working principle of die cutting is to use die cutting knife, steel knife and metal mold to apply certain pressure to the mold to cut the product into a certain shape. Among them, the mold is the key to product formation. Specifically, the raw materials of the product such as steel strips and plates pass through the mold continuously, and the die cutting knife cuts the original metamaterial on the mold to obtain the target product.

[0003] During the cutting process, the spacing and accuracy of the raw material movement are determined by the transportation mechanism. If the matching transportation mechanism has low accuracy, it may cause the obtained product to be deformed, or the cutting hole spacing is too large, resulting in waste of raw materials.

[0018] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0019] like Figure 1-4 As shown, a continuous die-cutting mold includes a top plate 1 and a bottom plate 2. The top plate 1 is provided with a guide hole 11, and the bottom plate 2 is provided with a guide column 3 passing through the guide hole 11. A mold base 4 and a pressure head 5 are also provided between the top plate 1 and the bottom plate 2. The top of the top plate 1 has a connecting portion 6212 connected to an external hydraulic device, the mold base 4 has a slide groove 41 through which the product continuously slides, and the slide groove 41 has a cavity 42 that matches the shape of the pressure head 5, wherein a through hole is provided on one side of the mold base 4, and a push rod 61 is provided in the through hole. The tail of the push rod 61 is connected to a button exposed on the outside of the mold base 4, and a spring 63 is provided between the button and the mold base 4. When the push rod 61 is pushed toward the slide groove 41, the push rod 61 squeezes the product in the slide groove 41.

[0020] The head of the push rod 61 is provided with a stopper 64 protruding from the surface of the shaft thereof, so that the head of the push rod 61 can be prevented from excessively retracting into the through hole.

[0021] The mold base 4 is connected with a cover plate by bolts, and the cover plate has a profile hole matched with the pressure head 5. The cover plate can prevent the safety risk caused by the product breaking and splashing.

[0022] The ram 5 includes a mounting plate 51 and a forming portion 52 integrally formed below the mounting plate 51, the forming portion 52 is used to press toward the cavity 42, the mounting plate 51 is fixed to the ground of the top plate 1, and a limiting column 7 facing the mounting plate 51 is provided on the mold base 4. The limiting column 7 can display the downward stroke of the ram 5, thereby improving the die-cutting efficiency.

[0023] Working principle:

[0024] The strip-shaped raw material (such as steel coil) is introduced from the slide groove 41 between the cover plate and the mold base 4, and can be transported by any transport mechanism, such as the conveying rollers arranged on both sides of the mold base 4. When the raw material moves, the cylinder arranged on one side of the mold base 4 pushes the button, and then the push rod 61 presses the side of the raw material to prevent the raw material from moving further. The hydraulic mechanism is connected to the connection part 6212 at the top of the top plate 1, driving the top to rise and fall, and then the pressure head 5 to rise and fall, and the pressure head 5 presses against the raw material, cutting out the steel sheet that matches the shape of the pressure head 5 and the cavity 42, and the steel sheet falls from the cavity 42 and is collected.

[0025] Beneficial effects:

[0026] Based on the set push rod 61 and button 62, the push rod 61 can be pressed against the side of the product to realize the start and stop of the product during transportation, so as to improve the accuracy of die-cutting; based on the set spring 63, when the pressing connection part 6212 is released, the connection part 6212 can automatically drive the push rod 61 to retract.

[0027] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
