Slider Components – Press block

by

The Press blocks/Guide blocksPress blocks for slider

a) The press blocks are used to lock the slider by securing the heads on both sides of the slider, to ensure the slider moves smoothly on the wear plate;

b) When a press block enters the mold cavity plate, clearance needs to be allowed on the side (as shown in the figure);

c) Dimensional Parameters: W > D + Slider Travel Distance
A usually ranges from 20 to 30MM
B usually ranges from 20 to 40MM

d) When a slider is a lot lower than the core and press block clearance is too large, the height of the slider head should be appropriately increased;

e) The press block applies the SK-3 material, which needs to be preheated.
