Description

Technical Field

[0001] This utility model relates to a mold for repairing outer cover parts. Background Technology

[0002] Currently, stamped parts are widely used in manufacturing industries such as aircraft and automobiles. Some outer surface coverings (referred to as "outer coverings") have very high requirements for quality and appearance, and the surface must be free of dents or defects.

[0003] Please see Figure 1 If the edge surface of the end 32 of the stamping groove 31 of the outer cover 3 is concave, it will seriously affect the appearance of the product. Currently, the method used to repair the outer cover is to manually select the outer cover with concave defects, isolate them, and polish them by hand. If the quality requirements still cannot be met, they must be abandoned and scrapped. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide an outer cover repair mold that can repair defective outer cover parts with dents, greatly reduce the scrap rate, improve product quality, increase the pass rate, and reduce waste.

[0005] The technical solution to achieve the above objective is: an outer cover repair mold, wherein the outer cover has multiple stamping grooves, characterized in that the repair mold includes an upper mold and a lower mold arranged opposite to each other, wherein:

[0006] The lower surface of the upper die is provided with at least one upper die groove that is adapted to the end of the stamping groove of the outer cover, and the edge of each upper die groove is connected with a reverse recess that is adapted to the edge of the end of the stamping groove of the outer cover.

[0007] The upper surface of the lower die is provided with at least one lower die protrusion that is adapted to the stamping groove of the outer cover, and the end of each lower die protrusion is connected to a reverse protrusion that is adapted to the edge of the end of the stamping groove of the outer cover.

[0008] The upper die is positioned above the outer cover, and the lower die is positioned below the outer cover. The upper die groove is fitted onto the end of the stamping groove of the outer cover, and the lower die protrusion is located inside the stamping groove of the outer cover. The reverse recess and the reverse protrusion are pressed against the upper and lower sides of the edge of the end of the stamping groove of the outer cover in a one-to-one correspondence.

[0009] In the aforementioned outer cover repair mold, there are multiple upper mold grooves and lower mold protrusions, all arranged sequentially from left to right.

[0010] In the aforementioned outer cover repair mold, multiple reverse recesses and multiple reverse protrusions are pressed one-to-one against the upper and lower sides of the edges of the ends of multiple stamping grooves on the outer cover.

[0011] In the aforementioned outer cover repair mold, upper positioning grooves are respectively provided on the bottom left and right sides of the upper mold; lower positioning grooves are respectively provided on the top left and right sides of the lower mold; and the upper positioning grooves are located directly above the corresponding lower positioning grooves.

[0012] This utility model of an outer cover repair mold can repair defective outer cover parts with dents, greatly reducing the scrap rate, improving product quality, increasing the pass rate, and reducing waste. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0018] Please see Figures 2 to 4 In the preferred embodiment of this utility model, the outer cover 3 has a plurality of stamping grooves 31, and an outer cover repair mold includes an upper mold 1 and a lower mold 2 arranged opposite to each other.

[0019] The lower surface of the upper die 1 is provided with at least one upper die groove 11 that matches the end of the stamping groove of the outer cover 3. The edge of each upper die groove 11 is connected to a reverse recess 12 that matches the edge of the end 32 of the stamping groove 31 of the outer cover 3. The upper surface of the lower die 2 is provided with at least one lower die protrusion 21 that matches the stamping groove 31 of the outer cover 3. The end of each lower die protrusion 21 is provided with a reverse protrusion 22 that matches the edge of the end of the stamping groove of the outer cover 3. In this embodiment, there are five upper die grooves 11 and five lower die protrusions 21. The five upper die grooves 11 are arranged sequentially from left to right on the lower surface of the upper die 1, and the five lower die protrusions 21 are arranged sequentially from left to right on the upper surface of the lower die 2. In this way, the recesses at the edges of the ends 32 of the five stamping grooves 31 can be repaired at one time.

[0020] Upper positioning grooves 13 are provided on the bottom left and right sides of the upper mold 1; lower positioning grooves 23 are provided on the top left and right sides of the lower mold 2.

[0021] Please see again Figure 4 In use, the outer cover repair mold of this utility model has an upper mold 1 positioned above the outer cover 3 and a lower mold 2 positioned below the outer cover 3. The upper mold groove 11 fits onto the end 32 of the stamping groove 31 of the outer cover 3, and the lower mold protrusion 21 is located inside the stamping groove 31 of the outer cover 3. The reverse recesses and reverse protrusions are respectively pressed against the upper and lower sides of the edge of the end of the stamping groove of the outer cover. The five reverse recesses 12 are respectively pressed against the upper side of the edge of the end 32 of the five stamping grooves 31 of the outer cover 3, and the five reverse protrusions 22 are respectively pressed against the lower side of the edge of the end 32 of the five stamping grooves 31 of the outer cover 3. The upper positioning groove 13 is located directly above the corresponding lower positioning groove 23. Then, by pressing the upper die 1 and the lower die 2 together, the dent at the edge of the end 32 of the stamping groove 31 can be repaired. After repair, the outer cover 3 is slipped by an oilstone, and the dent basically disappears, which can greatly reduce the scrap rate and improve product quality.

[0022] In summary, the outer cover repair mold of this utility model can repair defective outer cover parts with dents, greatly reducing the scrap rate, improving product quality, increasing the pass rate, and reducing waste.

[0023] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any changes or modifications to the above embodiments within the scope of the essential spirit of the present utility model will fall within the scope of the claims of the present utility model.
