The scissor lifting mechanism 30 is disposed between the frame 10 and the support table 20, the scissor lifting mechanism 30 is used for realizing lifting motion of the support table 20 within a certain range, and the scissor lifting mechanism 30 is in the prior art and will not be described herein. The roller table 40 is rotatably fitted on the top of the support table 20 by the rotary plate 70, and a plurality of carrier rollers are provided on the roller table 40 to facilitate movement of the mold.

The limiting seat 50 is of an annular structure, the limiting seat 50 is fixed on the supporting table 20 and is positioned between the supporting table 20 and the roller table 40, the height of the limiting seat 50 is lower than that of the rotating disc 70, the axis of the limiting seat 50 coincides with the rotation axis of the roller table 40, a plurality of limiting holes 51 are formed in the outer side wall of the limiting seat 50, and the limiting holes 51 are arranged in an annular array along the axis of the limiting seat 50. The locking mechanism 60 is arranged on the roller table 40, the locking mechanism 60 comprises a bolt 61 and a reset component, the bolt 61 is in plug-in fit with the limiting hole 51, and the reset component is used for applying elastic force to the bolt 61 so as to prevent the bolt 61 from exiting the limiting hole 51.

According to the die transfer platform truck disclosed by the embodiment, the limiting seat 50 is designed on the supporting table 20, and the plurality of limiting holes 51 are arranged in the annular array along the axis of the limiting seat 50, so that after the roller table 40 is rotated, the bolts 61 are inserted into the corresponding limiting holes 51, and the roller table 40 can be locked at a plurality of angle positions, so that the position of the frame 10 is not required to be adjusted, and the die change position of the frame can be adapted by rotating and locking the roller table 40. Meanwhile, the locking of a plurality of angle positions of the roller table 40 abandons the structure that the traditional rotary roller table 40 can only be locked at a limited rotation position, thereby meeting the transfer requirements of the die and the feeding and discharging requirements of the die in different scenes. In addition, the reset component is designed to prevent the plug pin 61 from exiting the limiting hole 51, so that the stability of the plug pin 61 matched with the limiting hole 51 is improved, and the safety of the plug pin in the transferring process and during the loading and unloading of the die is ensured.

In one embodiment, two pins 61 are provided, the two pins 61 are respectively disposed on two sides of the roller stand 40, the two pins 61 can be synchronously inserted into the corresponding two limiting holes 51, and the reset component is used for driving the two pins 61 to synchronously insert into or withdraw from the corresponding limiting holes 51. By designing the two bolts 61 and utilizing the reset assembly to synchronously drive the two bolts 61, the locking effect of the roller table 40 is ensured, and an operator can conveniently operate the bolts 61 at a plurality of positions to realize the locking or unlocking operation of the roller table 40.

Specifically, the reset assembly includes a linkage gear 62, two racks 63, two connecting rods 64, and a reset member 65, the linkage gear 62 is rotationally fitted on the roller table 40, and the axis of the linkage gear 62 coincides with the axis of the limit seat 50. Two racks 63 are respectively slidably fitted on the roller table 40, the two racks 63 are respectively arranged on both sides of the linking gear 62, and the two racks 63 are respectively engaged with the linking gear 62.
