A stamping mold group including a top plate, a bottom plate, a shaft sleeve, a guide column, a spring, a pressing plate, a pressing head and a sliding groove is designed. The material plate is pressed before stamping through the fit of the spring and a guide column to ensure the stable position of the material plate. And the precise cutting of the material plate is achieved through the matching of the L-shaped indenter and the sliding groove.
Effectively prevent material plate displacement, avoid material waste and product quality unqualified, and ensure the accuracy and efficiency of the products obtained from stamping.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of molds, in particular to a stamping mold group for a movable material plate. Background Art
[0002] Stamping dies include blanking dies, specifically dies that separate materials along closed or open contours, such as blanking dies, punching dies, cutting dies, incision dies, trimming dies, and cutting dies.
[0003] In the prior art, iron sheet products of a specific shape are generally obtained by punching and cutting a sheet with a stamping die. In order to improve production efficiency, the sheet is set in a continuous long strip, which is slowly fed into the stamping die, and the product is punched and cut while moving. In this process, the positioning of the sheet is particularly important. If the sheet is offset at the moment of stamping, the two adjacent stamping positions of the sheet will be too wide or too narrow, thereby wasting materials or causing unqualified product quality. Utility Model Content
[0004] The utility model aims to provide a stamping die set for a movable material plate.
[0005] In order to achieve the above purpose, the following technical solutions are adopted:
[0006] A stamping die set for a movable material plate comprises a top plate and a bottom plate, wherein shaft sleeves are arranged at the four corners of the top plate, a first guide column passing through the shaft sleeve is arranged on the bottom plate, a plurality of springs are arranged at the bottom of the top plate, the springs are connected to a pressure plate, a second guide column passes through the spring, the bottom end of the second guide column is fixedly connected to the pressure plate, and the top end thereof movably passes through the top plate, a pressure head for cutting the material plate is formed on the bottom surface of the pressure plate, a slide groove for the feed plate to pass through is arranged on the bottom plate, and a discharge hole matching the shape of the pressure head is arranged in the slide groove.
[0007] Furthermore, the slide groove is provided with a plurality of protrusions for blocking the material plate from moving forward, the bottom plate is connected to a lifting mechanism, and the material plate is driven by the conveying mechanism to move horizontally.
[0008] Furthermore, the pressure head is L-shaped.
[0009] Furthermore, a pressing portion matching the shape of the slide groove is formed on the bottom surface of the pressing plate, and the pressing head is formed on the bottom surface of the pressing portion.
[0010] By adopting the above scheme, the beneficial effects of the utility model are:
[0011] Based on the set spring and the second guide column, before stamping, the pressure head and the pressure plate first press the material sheet to prevent the material sheet from moving. The pressure head stamps the material sheet after the spring is compressed to the limit, which can prevent material sheet waste or avoid unqualified product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] 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.
[0018] like Figure 1-3 As shown, a stamping die set for a movable material plate 12 includes a top plate 1 and a bottom plate 2, wherein shaft sleeves 3 are arranged at the four corners of the top plate 1, and a first guide column 4 passing through the shaft sleeve 3 is arranged on the bottom plate 2, and a plurality of springs 5 are arranged at the bottom of the top plate 1, and the spring 5 is connected to a pressing plate 6, and a second guide column 7 passes through the spring 5, and the bottom end of the second guide column 7 is fixedly connected to the pressing plate 6, and its top end movably passes through the top plate 1, and a pressing head 8 for cutting the material plate 12 is formed on the bottom surface of the pressing plate 6, and a slide groove 9 for the feeding plate 12 to pass is arranged on the bottom plate 2, and a discharge hole 10 matching the shape of the pressing head 8 is arranged in the slide groove 9.
[0019] The chute 9 is provided with a plurality of protrusions 11 for blocking the material sheet 12 from moving forward. The bottom plate 2 is connected to a lifting mechanism, and the material sheet 12 is driven by the conveying mechanism to move horizontally. The pressing head 8 is L-shaped. A pressing portion 13 matching the shape of the chute 9 is formed on the bottom surface of the pressing plate 6, and the pressing head 8 is formed on the bottom surface of the pressing portion 13. In this way, the pressing portion 13 can press the material sheet 12 on the chute 9 to position the material sheet 12.
[0020] Working principle:
[0021] Based on the set spring 5 and the second guide column 7, before stamping, the pressure head 8 and the pressure plate 6 first press the material sheet 12 to prevent the material sheet 12 from moving. After the spring 5 is compressed to the limit, the pressure head 8 will stamp the material sheet 12, which can prevent the material sheet 12 from being wasted or avoid the quality of the product being substandard. After the material sheet 12 is stamped, a slot will be formed on the material sheet 12, and a convex point 11 is set. The convex point 11 can clamp the slot to prevent the material sheet 12 from moving forward, thereby ensuring the quality of the product obtained by stamping. After the stamping is completed, the lifting mechanism drives the bottom plate 2 to descend, and the convex point 11 does not clamp the material sheet 12, so the material sheet 12 can continue to move forward. The lifting mechanism rises again, and the convex point 11 clamps the material sheet 12 again. Among them, it is worth explaining that the material sheet 12 is driven by the conveying mechanism, so it will not rise and fall with the rise and fall of the bottom plate 2.
[0022] 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.
