Technical Field

[0001] This utility model belongs to the technical field of molding molds, specifically relating to a mold that uses a first molding head to bend the vertical flange of an unformed product into an acute angle to form a first-stage molded product, and then uses a second molding part to flatten the acute angle flange of the first-stage molded product to form a second-stage molded product; thereby achieving the flattening of the flange of the unformed product; this utility model is stable and reliable in operation, and can also prevent the flattening mold from scratching the surface of the product. Background Technology

[0002] In the prior art, when it is necessary to flatten the edge, a flattening mold is usually required. A common flattening mold usually includes an upper mold and a lower mold. The upper mold and the lower mold work together to flatten the edge in one step. This makes the structure of the flattening mold relatively complex, and it will also scratch the surface of the product, resulting in a high defect rate.

[0003] To address this, we have developed a mold that uses a first forming head to bend the vertical flange of an unformed product into an acute angle to form a first-stage formed product, and then uses a second forming part to flatten the acute angle flange of the first-stage formed product to form a second-stage formed product; thereby achieving the flattening of the flange of the unformed product; this utility model is stable and reliable in operation, and can also prevent the flattening mold from scratching the surface of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flattening mold, comprising an upper template, a middle plate, and a lower mold; a first forming head and a second forming head are sequentially arranged on the lower surface of the upper template; a first through hole and a second through hole are vertically arranged on the middle plate; the first forming head can be inserted into the first through hole, and the second forming head can be inserted into the second through hole; a forming hole is provided on the lower mold, and the second forming head can be inserted into the forming hole; a first forming part is provided at the lower part of the first forming head; the first forming head is used to bend the vertical flange of the unformed product into an acute angle to form a first-formed product; a second forming part is provided at the lower part of the second forming head; the second forming part is used to flatten the acute-angle flange of the first-formed product to form a second-formed product.

[0006] Preferably, the angle between the first forming part and the horizontal plane is 30°, 45°, or 60°.

[0007] Preferably, the second forming part is a right-angle protrusion; the protrusion can be inserted into the forming hole, and the right-angle protrusion cooperates with the forming hole to flatten the acute angle of the first forming product to form the second forming product.

[0008] Compared with the prior art, the present invention provides a flattening mold, which has the following beneficial effects: The flattening mold of this utility model utilizes a first forming head to bend the vertical flange of the unformed product into an acute angle to form a first-formed product, and then uses a second forming part to flatten the acute angle flange of the first-formed product to form a second-formed product; thereby realizing the flattening of the flange of the unformed product; this utility model is stable and reliable in operation, and can also prevent scratching the surface of the product.
