Further, one side of the upper stamping core is formed with a side punching groove.

Further, the side stamping groove is located on the path of the reciprocating motion of the side stamping core.

Further, the moving direction of the floating plate is perpendicular to the moving direction of the side stamping core.

Further, the number of guide columns is 2 and symmetrically disposed on both sides of the lower die holder.

Further, the return spring is sleeved on the outer circumference of the guide post.

Further, the return spring and the return spring are cylindrical coil springs.

Further, the side punching cylinder comprises a cylinder block and a cylinder rod; the cylinder rod moves relative to the cylinder block; the cylinder block is fixed to the side stamping support; and the side stamping core is fixed to the cylinder rod.

Further, the pressure movable member includes: a rod portion and an end portion; the rod portion is cylindrical; the end portion is formed in a disk shape; and the end portion is disposed at one end of the rod portion.

Further, the homing spring is sleeved on the rod portion; one end of the homing spring is in contact with the lower end of the end portion; and the other end of the homing spring is in contact with the lower mold base.

The invention is advantageous in that:

In a mold operation process, the upper and lower direction forming and the lateral forming production are high.

The pressure sensor is in contact with the pressure movable member, and the pressure value of the pressure sensor can determine the moving position of the floating plate. Highly accurate, it can be stamped at the specified position on the side wall of the part. The homing spring applies a spring force to the pressure movable member to prevent the pressure sensor from contacting the pressure movable member to generate a peak to cause distortion. The setting of the homing spring also prevents damage to the pressure sensor caused by excessive pressure.
