When the mold is closed, the matched die and punch Forming metal blanks into automotive parts with the desired shape. It should be noted that there are many ways to pivotably connect the lower part of the screw rod to the support plate, for example, connect the support plate and the lower part of the screw rod through a swivel joint (not shown), so as to ensure that the screw rod can rotate relative to the support plate Simultaneously, can drive support plate 5 lifting. Alternatively, the support plate 5 and the screw 2 can be connected through a bearing (not shown), specifically, the outer ring of the bearing can be fixedly connected to the support plate 5, and the lower part of the screw 2 can be fixedly connected to the inner ring of the bearing. In addition, the metal forming mold of the utility model should also be provided with a stripping mechanism (not shown in the figure). Since the stripping mechanism is prior art and well known to those skilled in the art, its specific structure will not be repeated here.

In the embodiment of the utility model, as shown in Figure 1, the support plate 5 is provided with an axial through hole (not shown), and a sleeve 3 is fixed in the axial through hole, and the sleeve 3 is provided with an internal thread, and the screw rod 2 is rotatably mounted on the sleeve 3 through screw fit. It should be noted that it is also possible to directly provide an internal thread in the axial through hole, and the screw rod is rotatably mounted on the internal thread.

Specifically, as shown in Figure 1, the position adjacent to the upper mold base 4 and the guide column 7 is fixedly connected with a guide sleeve 8), the guide sleeve 8 is sleeved on the guide column 7 and can move vertically along the guide column 7, Thus, the support plate 5 can be vertically slidably mounted on the guide post 7 .

Further, as shown in Figure 1, the bottom wall of the upper die base 4 corresponds to the area around the periphery of the punch 10 with at least one limiting column 14 extending downward, and the upper wall of the die 13 is set at a position opposite to the limiting column 14. There is a limiting hole 12 for the insertion of the limiting column 14, and a buffer mechanism is installed in the limiting hole 12 to buffer the limiting column 14 when the mold is closed, thereby buffering the downward movement of the upper mold base, which can effectively avoid It solves the problem that when the mold clamping mechanism exerts too much pressure, the collision between the punch and the die will directly lead to damage, thereby greatly improving the service life of the mold.

Specifically, as shown in Figure 1 and Figure 2, the buffer mechanism includes a spring seat (123) located at the top of the limit hole (12), a spring (122) whose lower end is connected to the spring seat, and a spring (122) connected to the spring (122) The limit block (121) at the upper end, in the mold closing process, the limit post (14) can descend to offset with the limit block (121).

Further, as shown in FIG. 1 , an upper mold fixing plate 11 is also provided between the support plate 5 and the die 13 , and the support plate 5 , the die 13 and the upper die fixing plate 11 are fastened by bolts 9 .
