Description

Technical Field

[0001] This utility model relates to the field of edge-pressing mold technology, specifically an edge-pressing mold for both sides of a product cutting edge. Background Technology

[0002] A double-sided deburring die is a composite die used to simultaneously cut and remove burrs, primarily applied in processes such as stamping, injection molding, and forging. Traditional deburring methods involve manual removal, resulting in uneven finishes that fail to meet aesthetic requirements and are very slow. The new die, by creating rounded corners on both sides, uses these corners to contour and remove sharp edges from the product.

[0003] The blank material to be trimmed is placed into the lower mold, and the upper clamping plate closes with the lower mold to trim the product edges and remove burrs. During this process, the blank material needs to be aligned with all four sides and placed into the deburring holes of the lower mold, which is time-consuming. Therefore, a deburring mold for both sides of the product edge trimming is needed to solve the above problem. Utility Model Content

Pull the connecting plate 250 to move the guide plate 25 out of the lower template 13. The upper clamping plate 12 moves downward and closes with the lower template 13 to perform edge trimming and deburring treatment on the product.

[0037] This step allows the blank material to be placed quickly and accurately into the deburring hole 17, improving processing efficiency.

[0038] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The limiting component includes a threaded groove 30 and a limiting rod 31. The threaded groove 30 is opened at the other end of the guide plate 25 away from the support plate 20, and the limiting rod 31 is screwed into the threaded groove 30.

[0040] The threaded groove 30 serves as a connection, and the limiting rod 31 serves as a limit to prevent the guide plate 25 from falling off from the upper limit plate 23 and the lower limit plate 24.

[0041] Working principle:

[0042] Two guide plates 25 are connected and fixed with a connecting plate 250. The end with the threaded groove 30 is inserted between the upper limit plate 23 and the lower limit plate 24. After the end with the threaded groove 30 is moved out of the upper limit plate 23, the limit rod 31 is rotated and screwed into the threaded groove 30.

[0043] This step prevents the guide plate 25 from falling off the upper limit plate 23 and the lower limit plate 24 when it is pulled outward.
