Obviously, the described embodiments are only part of the embodiments of the die, rather than all the embodiments of the die. Based on the embodiments of the die, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the die.

[0020] Referring to Figs. 1-3As shown, it comprises an upper die 1 and a lower die 2, a plurality of guide rods are arranged between the upper die 1 and the lower die 2, a male die 4 is arranged below the upper die 1, a female die 3 is arranged above the lower die 2 and opposite to the male die 4, a plurality of buffer assemblies are arranged on the lower side of the upper die 1, a plurality of guide blocks 5 are arranged below the upper die 1, and a plurality of guide grooves 6 matched with the guide blocks 5 are formed in the upper die 2;

[0021] The buffer assembly comprises a movable groove 9 vertically formed in the upper die 1, a buffer block 7 slidably arranged in the movable groove 9, the height of the buffer block 7 being the same as the depth of the movable groove 9, a compression groove 10 formed in the upper end of the movable groove 9, and a buffer spring 11 arranged in the compression groove 10 and connected to the inner wall of the compression groove 10 and the buffer block 7;

[0022] A plurality of guide sliding blocks 8 are arranged on the periphery of the buffer block 7, and a plurality of sliding grooves matched with the guide sliding blocks 8 are formed in the movable groove 9, the guide sliding blocks 8 being slidably arranged in the sliding grooves;

[0023] A plurality of balance air channels 12 are formed in the upper die 1 and connected to each compression groove 10;

[0024] The guide block 5 has a quadrangular frustum structure;

[0025] The top surfaces of the guide sliding block 8 and the buffer block 7 are aligned, the length of the guide sliding block 8 is smaller than the height of the buffer block 7, and wear-resistant coatings are arranged on the guide block 5 and the guide groove 6.

[0026] The working principle and use process of the utility model are as follows:

[0027] After the mold is installed in place, due to the elastic force of the buffer spring 11, the buffer block 7 is pushed out of the surface of the upper die 1, after the material is put in, the upper die 1 can be pressed down by the hydraulic equipment, so that the buffer block 7 gradually contacts the surface of the lower die 2, and then the buffer spring 11 is compressed, the impact generated during contact is buffered, and then the upper die 1 contacts the lower die 2, the material is formed by stamping through the female die 3 and the male die 4, after completion, the upper die 1 is lifted, the buffer block 7 is pushed out again under the action of the buffer spring 11, and due to the existence of the balance air channel 12, the air pressure on the upper and lower sides of the buffer block 7 can be balanced, and the movable block will not be blocked due to air pressure;

[0028] Since the bottom surface of the guide sliding block 8 is higher than the buffer block 7, the guide sliding block 8 will not contact the lower die 2, thereby preventing force damage;

[0029] After being used for a period of time, the upper and lower dies 2 may deviate horizontally, during the pressing process of the upper die 1, the guide block 5 enters the guide groove 6 and automatically slides along the peripheral side wall, thereby adjusting the horizontal position between the upper die 1 and the lower die 2, so that the two are automatically aligned.
