Abstract

The utility model discloses a chip frame mould which comprises a first station plunger chip and a second station plunger chip that are fixed on a mould fixing plate according to the processing sequence; the punching end of the first station plunger chip takes the shape of a cylinder with a chamfer, and the punching end of the second station plunger chip take the shape of a cylinder with a step chamfer. As secondary deep drawing technique is adopted by the chip frame mould, a groove at the middle part is subjected to deep drawing sequentially by the first station plunger chip and the second station plunger chip, and the drawing depth of each deep drawing is shallower, therefore, connecting strips at the four corners of a chip frame are not easy to break, and the finished product ratio is higher.

Description

The chi frame mould

Technical field

The utility model relates to a kind of diel, particularly relates to a kind of chi frame mould.

Background technology

The chi frame 9 (as shown in Figure 3) that is used for fixing chip is the recessed groove in middle part 91, four jiaos of workpiece with tiny connection strap 92.Because this connection strap 920 minutes is tiny, in drawing process, if the degree of depth of pull and stretch is bigger, near critical value, the connection strap 92 that then is positioned at four jiaos of frameworks is broken easily, and makes product rejection.

The utility model content

The chi frame mould that provides a kind of yield rate high is provided the purpose of this utility model.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of chi frame mould, and it comprises the first station drift and the second station drift; The described first station drift and the second station drift are fixed on the mold fixed plate along processing sequence; The punching press end of the described first station drift is the column with a chamfering, and the punching press end of the second station drift is the column with ladder chamfering.

After adopting such scheme, because the utility model adopts secondary deep-drawing technology, by the first station drift and second station drift pull and stretch central slot one by one, the degree of depth of each pull and stretch is more shallow, connection strap on four jiaos of the chi frames is difficult for being broken, and the yield rate of product is higher.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is the utility model cutaway view;

Fig. 2 A, Fig. 2 B are the product figure behind the utility model pull and stretch first time;

Fig. 2 C, Fig. 2 D are the product figure behind the utility model pull and stretch second time;

The product figure of Fig. 3 chi frame.

The specific embodiment

As shown in Figure 1, the utility model is a kind of chi frame mould, and it comprises the first station drift 1 and the second station drift 2; The described first station drift 1 and the second station drift 2 are fixed on the mold fixed plate 10 along processing sequence; The punching press end 11 of the described first station drift 1 is the column (with reference to figure 2B) with a chamfering, and the punching press end 21 of the second station drift 2 is the column (with reference to figure 2D) with ladder chamfering.

Process of the present utility model:

During punching press, the pull and stretch of punching press for the first time goes out the semi-finished product 9A shown in Fig. 2 A, Fig. 2 B; The pull and stretch of punching press for the second time goes out the semi-finished product 9B shown in Fig. 2 C, Fig. 2 D.

Emphasis of the present invention just is: adopt secondary deep-drawing punching out chi frame.

Claims

1, a kind of chi frame mould is characterized in that: it comprises the first station drift and the second station drift; The described first station drift and the second station drift are fixed on the mold fixed plate along processing sequence; The punching press end of the described first station drift is the column with a chamfering, and the punching press end of the second station drift is the column with ladder chamfering.
