Abstract

The invention relates to the technical field of powder forming, and provides a cold disc cylinder heat exchange layer pressing die which comprises a pressing assembly, a fixing seat, a plurality of forming templates, a demoulding assembly, at least three supporting rods, at least three claw seats, at least three clamping claw seats, and clamping grooves, wherein the fixing seat is used for fixing a cold disc, the heat exchange rods are fixedly arranged on the cold disc, the forming templates are sequentially stacked on the cold disc, the demoulding assembly comprises a supporting cylinder, the supporting rods are annularly arranged on the supporting cylinder, the supporting springs are sleeved on the supporting rods, the at least three claw seats are fixedly arranged on the outer wall of the supporting cylinder, the clamping claws are rotatably arranged on the claw seats, and the periphery of the forming template is uniformly annularly provided with clamping grooves. Therefore, the adhesive force between each stage of molding template and the heat exchange layer is reduced by arranging the multistage molding templates. Through the transmission of the driving wheel and each driving rod, each claw synchronously applies axial drawing force to the molding templates, and the demolding operation of each molding template is sequentially completed. The demolding process of the molding template only receives axial drawing force, so that the surface damage of the heat exchange layer caused by twisting or uneven stress is avoided. The demolding quality and efficiency are improved.
