To this end, an embodiment of the present utility model proposes a blanking die 1000, particularly as shown in fig. 1 to 3 of the drawings of the specification.

Referring to fig. 1, a blanking die 1000 according to an embodiment of the present utility model includes a frame 100, an upper die 200, and a lower die 300. The upper die 200 is connected to the frame 100 in a driving manner in the up-down direction, that is, the frame 100 can drive the upper die 200 to move up and down. Specifically, the stand 100 includes a stand body 110 and a driving member 120, where the driving member 120 is fixedly disposed on the stand body 110. The driving member 120 may be a cylinder, a motor, or the like. Referring to fig. 1 and 2, a platen 210 is provided at the bottom of the upper die 200, and a plurality of punching pins 220 are further fixedly provided at the bottom of the upper die 200. The platen 210 is movably connected with the plurality of punching pins 220 in the up-down direction, that is, the platen 210 can move in the up-down direction.

Referring to fig. 1, the lower die 300 is fixed to the frame 100, and in particular, the lower die 300 is fixed to the frame body 110. It should be noted that, the lower die 300 is provided with a positioning cavity 310, a bottom wall of the positioning cavity 310 is provided with a plurality of punched holes 311, and the plurality of punched holes 311 are arranged corresponding to the plurality of punching pins 220. It will be appreciated that the shower face cover is placed within the positioning cavity 310. During processing, the upper die 200 moves downward until the platen 210 presses against the shower face cover. The upper die 200 continues to move downward and the platen 210 remains pressed against the shower face cover. The plurality of punching pins 220 continue to move downward until the plurality of punching pins 220 pass through the plurality of punching holes 311 to punch a plurality of holes in the shower face cover at a time. It can be appreciated that by the arrangement described above, the efficiency of punching 311 of the shower face cover is greatly improved. In one embodiment, the cross-sections of punch 311 and punch pin 220 are both circular.

Referring to FIG. 2, in one embodiment, a plurality of punched holes 311 are uniformly spaced at the bottom wall of the positioning cavity 310. Correspondingly, the plurality of punching pins 220 are also uniformly spaced. Therefore, the holes punched on the shower face cover are uniformly arranged at intervals, and the requirements of customers are met.

Referring to fig. 2 and 3, the bottom of the upper mold 200 is further provided with an elastic member 230. It should be noted that, the elastic member 230 is sleeved on the punch pin 220 and is located between the platen 210 and the upper die 200. It will be appreciated that as the plurality of pins 220 move downward until the plurality of pins 220 pass through the plurality of punched holes 311, the distance between the platen 210 and the upper die 200 shortens, deforming the resilient member 230. When the upper die 200 moves upward, the plurality of punching pins 220 move upward, the distance between the platen 210 and the upper die 200 becomes longer, and the elastic member 230 is restored to the original state, so that the relative positions of the platen 210 and the punching pins 220 are returned to the original state. In one embodiment, the elastic member 230 is a rubber sleeve. It will be appreciated that rubber has good elasticity and that the use of rubber sleeves as the elastic members 230 can well meet the operating requirements of the blanking die 1000. The elastic member 230 may also be a spring or the like.

In one embodiment of the present utility model, the blanking die 1000, the platen 210 can be mated to the positioning cavity 310. It will be appreciated that with the arrangement described above, the platen 210 is better able to compress the shower face cover. In one embodiment, the positioning cavity 310 and the platen 210 are both circular in cross-section. It can be understood that the shower face cover manufactured in this way is more attractive and meets the requirements of users. The lower die 300 is provided with a vent groove 320, and the vent groove 320 communicates with the positioning cavity 310. It will be appreciated that when the platen 210 is engaged with the positioning chamber 310, the space in the positioning chamber 310 is compressed, and if the gas in the positioning chamber 310 cannot be exhausted, the engagement of the platen 210 with the positioning chamber 310 is affected. Therefore, by providing the exhaust groove 320, the gas in the positioning chamber 310 can be exhausted when the platen 210 is fitted to the positioning chamber 310. In one embodiment, the plurality of vent slots 320 is provided, and the plurality of vent slots 320 are disposed around the rim of the positioning cavity 310. It is understood that by providing a plurality of the exhaust grooves 320, exhaust can be accelerated. The shape and size of the vent groove 320 are not particularly limited, and may be selected according to practical situations.

Referring to fig. 1, a punching die 1000 according to an embodiment of the present utility model is provided with a guide hole extending in the up-down direction in an upper die 200 and a guide bar 330 in a lower die 300. Wherein, the guide rod 330 is inserted into the guide hole. It can be appreciated that by providing the guide holes and the guide bars 330, the upper die 200 is made more stable when moving up and down.

In one embodiment, two guide holes are provided, and the two guide holes are respectively provided at two ends of the upper die 200 in the length direction. The guide bars 330 are provided in two, and the two guide bars 330 are respectively provided at both ends of the lower die 300 in the length direction.
