An automatic screen changer for a plastic resin forming apparatus is provided to prevent impurities from being generated in molten resin by preventing resin from being carbonated for the forward/backward movement of a screen. An automatic screen changer for a plastic resin forming apparatus comprises a body(10), a hollow cylinder(20), a screen receiving block(40), a pressing roller(48), and a driving unit. The body is formed with a resin inlet(12), a resin outlet(14) and a chamber(11) communicated with the resin inlet and the resin outlet. The hollow cylinder is formed with a hollow(21) communicated with a resin passage. The pressing roller is positioned opposite to the screen receiving block. The driving unit drives the hollow cylinder and the pressing roller.
