Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] Such as Figure 1 ~ Figure 3 As shown, a mold with stable shape according to the present invention includes an upper mold plate 1 and a lower mold bottom plate 16,
[0023] The upper template 1 is connected with a die 2, the upper template 1 on both sides of the die 2 is provided with an upper bushing 3, the die 2 is provided with a groove 6, and a positioning groove 5 is arranged around the groove 6;
[0024] The bottom plate 16 of the lower mold is connected with a reinforcing plate, the reinforcing plate is provided with a lower template 14, the middle surface of the lower template 14 is provided with a lower mold mechanism, the lower template 14 on both sides of the lower mold mechanism is provided with a lower bushing, and the lower bushing A guide shaft 7 is fixed, and the guide shaft 7 cooperates with the upper sleeve 3 to fix the movement direction of t...

The scheme provided by the invention to solve technical problems is simple and practical and solves the problems that a drawing mold is complicated in structure, a locating mechanism is specially arranged for a blank pressing plate, and the using efficiency is low. The blank pressing plate is provided with a locating pin, the locating pin is mounted on the blank pressing plate through a countersink and a screw in clearance fit, and a female die is correspondingly provided with a locating slot slidably matched with the locating pin. When the female die starts to be in contact with the blank pressing plate, the locating pin is matched with the locating slot corresponding to the female die; in the drawing process, the relative positions of the blank pressing plate and the female die are not changed, so that an imbalanced lateral force generated in the drawing process of the blank pressing plate is eliminated. As a spring is arranged, the mold structure has an energy storage piece, so thata workpiece is separated from the mold better; the blank pressing plate is movably connected to a locating shaft, so that the demand on the shaft manufacturing precision can be reduced, the cost is lowered, and a male die and the female die can be quickly located by matching the locating pin with the locating slot.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a stable mold. Background technique [0002] Drawing is one of the important forming methods of sheet metal parts, and the blank holder is one of the important parts in the drawing die. As a movable part, the binder ring is typically guided by a guide plate guide and a guide post guide. The guide plate guide is generally suitable for large-scale casting drawing dies, and the guide plate guide has better lateral anti-lateral ability. The guide post guide is generally suitable for small steel plate molds. The guide post guide is weak in offsetting the lateral force, especially when the stroke of the blank holder is relatively large. However, due to the different feeding speed and incomplete resistance of the surrounding sheets during drawing, there are often different degrees of lateral force or even alternating lateral force on the blank holder. After a certain ...
