Preferably, the upper end face of the blank-changing lower die is provided with at least two counter bores, positioning pins are inserted into the counter bores, and the upper punch is provided with positioning pin holes matched with the positioning pins. According to the scheme, the pin hole is sleeved on the pin shaft, so that the upper punch is in sliding connection with the blank-changing lower die.
Preferably, the number of the counter bores is 4, and the 4 counter bores are arranged in a rectangular shape. In the scheme, 4 counter bores are arranged, so that the transverse deviation between the upper punch and the blank-changing lower die is effectively prevented.
For optimization, the 4 counterbores are symmetrical relative to the central plane. In the scheme, the 4 counter bores are symmetrical relative to the central plane, so that the upper punch can be prevented from inclining due to uneven resistance of the 4 counter bores during forging.
Preferably, two ends of the variable blank cavity far away from the central plane are respectively provided with a bulge. Through the arch that sets up in this scheme, when the blank is impressed to the punching press head, can extrude the blank to both ends to the thinner part in forging and pressing derail pedestal blank both ends.
Preferably, the height of the stamping head is smaller than the depth of the blanking cavity. The high degree that becomes blank chamber of punching press head in this scheme to when making the punching press head impress the blank, can not run through the blank.
The utility model has the advantages that: the utility model discloses a rail seat system base mould is through setting up the drift along vertical and become base lower mould to make the drift along vertical and become base lower mould slip joint, thereby prevent blank in-process well drift and become base lower mould lateral deviation, the utility model discloses the preparation of two blanks can be accomplished to one time blank making, treat to saw open the blank along the central plane with the sawing machine after the blank cooling, thereby obtain two rail seat body blanks, simple structure, efficient, location are accurate.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1~8, the utility model discloses a rail seat system base mould, including becoming base lower mould 1 and setting up the top punch 2 in variant base lower mould 1 top, top punch 2 is square board, and the terminal surface is equipped with the punching press head 7 of two symmetries of each other under the top punch 2, and punching press head 7 integrated into one piece is on top punch 2, and the plane of symmetry between two punching press heads 7 is the central plane, and whole rail seat system base mould homogeneous phase is symmetrical for the central plane.
The blank changing lower die 1 is square, a blank changing cavity is formed in the upper end face of the blank changing lower die 1 and is symmetrical relative to a central plane, and a certain inclination is arranged on the periphery of the blank changing cavity, so that blank discharging is facilitated.
The blank changing cavity is square, and the height of the punching head 7 is smaller than the depth of the blank changing cavity.
