Abstract
Disclosed is a mold with sliders employed for molding a plastic product having a first lateral bulge and a second lateral bulge in different directions. The mold comprises a fixed half, an angle pin, a moving half, a main slider and a tilted slider. The angle pin comprises an angle pin body with two opposite forcing surfaces. The main slider comprises a tilted slide track corresponding to the second lateral bulge. A pin slot is formed on the main slider. Two weighted surfaces are formed on the main slider at the opposite two sides of the pin slot. The angle pin body can slidably dip into the pin slot and the driving guide slot. By acting on the tilted slider and then on the main slider with the angle pin body, the mold can respectively complete the procedure of pulling out laterally bulges aslant and horizontally.
