Description
[technical field]
The relevant a kind of mould structure for bending of the present invention, particularly relevant a kind of mould structure for bending slant negative angle.
[background technology]
When doing portable set outer casing members such as PDA(Personal Digital Assistant), mobile phone when us, often run into this class situation of folding negative angle (we call negative angle to the bending angle greater than 90 ° angle usually), by traditional method is as shown in Figure 1, Figure 1 shows that the side view of the negative angle mould structure for bending of prior art.Product 100 is located at counterdie goes on the son 300, formerly with after product 100 foldings one angle (angle as shown in phantom in Figure 1), with 10 ° of left and right sides negative angles of the drift 200 mandatory formation of vertical cornerite, after negative angle is greater than 15 °, conventional method just is difficult to reach dreamboat, go back imperfection on the structure, so need take other method.
Utilize the traditional structure of above-mentioned prior art to have following shortcoming: the negative angle angle can not be too big; Bending cost height (palpus two one-step formings); The bending instability is easy to generate the off normal in the first step and second step, thereby causes product 100 flatnesses to exceed standard; It is very accurate that drift 200 highly need be joined mould, and group Mo Ji Intraoperative is required height, as join mould and forbidden often to have counterdie to go into sub 300 explosion situations appearance.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of mould structure for bending slant negative angle, utilize this structure can realize solving the angle limits problem, reduce the bending cost, reduced the appearance of bending destabilizing factor, the quality of product is further guaranteed; Shortened and joined the mould time, prolonged die life.
For reaching above-mentioned purpose, mould structure for bending slant negative angle of the present invention, this structure can be used for the pressing and bending to the product negative angle, and this structure comprises:
One patrix, it comprises a train wheel bridge, this train wheel bridge is provided with one and drives drift, one section following row space place, this train wheel bridge lower end is provided with a baffle plate, this baffle plate lower end is provided with a stripper plate, be positioned at above-mentioned driving drift lower end in this stripper plate and be provided with an oblique storage tank, this oblique storage tank is provided with oblique moulding drift;
One counterdie, it comprises a lower bolster, the movable forming slide that is provided with in this lower bolster, this forming slide one side is a bending oblique angle, this bending oblique angle is parallel with above-mentioned oblique moulding drift one side, this forming slide below is provided with one first jigger pin, and the corresponding above-mentioned oblique storage tank of this counterdie below is provided with one second jigger pin.
Compared to prior art, mould structure for bending slant negative angle of the present invention, utilize this structure, forming slide is pressed into lower bolster by stripper plate in the mould mold closing, oblique moulding drift also heads into stripper plate fully by second jigger pin, with product maintenance to be formed, enter completed state, the beginning moulding, when mould continue closed because of drive drift continue descending, thereby promote oblique moulding drift along oblique storage tank in the stripper plate to descending, carry out the bending action, former road is returned after the execution, realizes product wide-angle bending action.Thereby solve the angle limits problem, product that can the bigger negative angle of bending reduces bending cost (only needing one-step shaping), has reduced the appearance of bending destabilizing factor, and the quality of product is further guaranteed, has shortened and has joined the mould time, has prolonged die life etc.
For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 illustrates the side view into the negative angle mould structure for bending of prior art.
Fig. 2 illustrates and is side-looking state profile before the mold closing of mould structure for bending slant negative angle one preferred embodiment of the present invention.
Fig. 3 illustrates and is side-looking state profile in the mold closing of mould structure for bending slant negative angle one preferred embodiment of the present invention.
Fig. 4 illustrates the mold closing rear side viewing state profile into mould structure for bending slant negative angle one preferred embodiment of the present invention.
[specific embodiment]
Please consult Fig. 2, Fig. 3, Fig. 4 jointly, it illustrates respectively and is side-looking state profile, mould structure for bending slant negative angle mold closing rear side viewing state profile of the present invention in side-looking state profile, the mould structure for bending slant negative angle mold closing of the present invention before the mould structure for bending slant negative angle mold closing of the present invention.
For reaching above-mentioned purpose, mould structure for bending slant negative angle of the present invention, this structure can be used for the pressing and bending to the product negative angle, and this structure comprises:
One patrix 1, it comprises a upper bolster 14, these upper bolster 14 lower ends are provided with a train wheel bridge 13, this train wheel bridge 13 is provided with one and drives drift 15, these one section following row space, 12 places, train wheel bridge 13 lower ends are provided with a baffle plate 11, these baffle plate 11 lower ends are provided with a stripper plate 10, are positioned at above-mentioned driving drift 15 lower ends in this stripper plate 10 and are provided with an oblique storage tank 16, are provided with oblique moulding drift 17 in this oblique storage tank 16;
