Fig. 1 is a cross-sectional view of an upper die structure provided in some embodiments of the present application.

As shown in fig. 1, in a first aspect, an embodiment of the present application provides an upper die structure, including an upper die body 10 and a pressing member 20, where the upper die body 10 includes a main body 11 and a first guide portion 12 connected to the main body 11, the main body 11 has a first side P1 and a second side P2 that are oppositely disposed along a first direction X, the first guide portion 12 includes a first guide sub-portion 13 and a second guide sub-portion 14 that are sequentially disposed along a second direction Y, the first guide sub-portion 13 is located between the second guide sub-portion 14 and the main body 11, and the first guide sub-portion 13 protrudes toward a direction approaching the first side P1 along the first direction X relative to the second guide sub-portion 14; the pressing member 20 is slidably disposed along the second direction Y relative to the main body 11, the center of gravity of the pressing member 20 is disposed near the second side P2, the pressing member 20 is located on a side of the first guiding portion 12 near the first side P1 along the first direction X, and is respectively attached to the first guiding sub-portion 13 and the second guiding sub-portion 14, and the second direction Y is perpendicular to the first direction X.

The first direction X may be a longitudinal direction or a width direction of the main body 11, and the second direction Y may be a thickness direction of the main body 11, and it should be clear that the second direction Y may be a gravitational direction during the pressing process. It should be clear that the last mould structure of this application can be applied to in the vehicle, is particularly useful for new energy automobile, and it can regard as the last mould structure of punching press of each spare part of automobile body, of course, the last mould structure of this application can also be applied to other fields, to the punching press to waiting in other fields to punch out the part, for example, the last mould structure of this application can be used to waiting to punch out the part on the bicycle, perhaps, the last mould structure of this application can also be used to waiting to punch out the part in the wrist-watch to punch out.

The pressing member 20 and the main body 11 may be connected by an external driving mechanism, for example, the pressing member 20 and the main body 11 may be connected by a linear driving motor, or the pressing member 20 and the main body 11 may be connected by a hydraulic cylinder, an air cylinder, a screw, or the like, which is not particularly limited in this embodiment. The side of the pressing member 20, which is close to the second side P2 along the first direction X, is respectively attached to the first guiding sub-portion 13 and the second guiding sub-portion 14, so that the pressing member 20 can play a guiding role in the sliding process along the second direction Y.

It will be appreciated that the swage 20 is used to compress a part to be machined, and because the part to be machined is typically irregularly shaped, the swage 20 is typically irregularly shaped with its center of gravity offset to one side for adaptation to the part to be machined. When the center of gravity of the press 20 is disposed near the second side P2, during the process of sliding the press 20 along the second direction Y relative to the main body 11, under the action of gravity, a side of the press 20 near the main body 11 along the second direction Y may be inclined toward a direction near the second side P2, and a side of the press 20 far from the main body 11 along the second direction Y may be inclined toward a direction near the first side P1, at this time, if the part to be punched is punched by the inclined press 20, the part to be punched may generate an indentation or a non-uniform punching condition, which affects the punching precision.

Therefore, in the present embodiment, by providing the first guide sub-portion 13 protruding in the first direction X toward the direction approaching the first side P1 with respect to the second guide sub-portion 14, when the press member 20 is provided on the side of the first guide portion 12 approaching the first side P1 in the first direction X and respectively engaged with the first guide sub-portion 13 and the second guide sub-portion 14, the side of the press member 20 approaching the main body portion 11 in the second direction Y can be abutted by the first guide sub-portion 13 to prevent the side of the press member 20 approaching the main body portion 11 in the second direction Y from being inclined toward the direction approaching the second side P2, thereby reducing the risk of occurrence of an indentation or uneven press of the part to be pressed when the part to be pressed is pressed by the press member 20, and improving the press precision of the part to be pressed.

In addition, in the embodiment of the application, the second guiding sub-portion 14 abuts against one side, close to the main body portion 11, of the pressing piece 20 along the second direction Y, so that the pressing piece 20 is prevented from tilting, the centering difficulty of the die in the die assembly process can be reduced, and the die assembly is convenient.
