9. The mold removing mechanism of an injection molding machine for processing square-shaped plastic molds according to claim 1, wherein the mold removing method of the mold removing mechanism comprises the following steps:
s1, before injection molding, switching on a power supply, heating the mold through the semiconductor refrigerating sheet (11), wherein the preheated mold can effectively avoid the mold sticking phenomenon during subsequent demolding and cannot hinder the working progress;
s2, when the die is subjected to injection molding, the air bag (62) expands and deforms due to the high temperature after the injection molding, the vertical sliding block (63) is driven to move upwards, and then the transverse sliding block (65) is driven to move in the movable groove (10) through the inclined rod (64);
s3, when the positive and negative contacts on the bottom side of the push rod (66) are reversely connected with the contacts on the upper and lower sides of the semiconductor refrigerating sheet (11), the semiconductor refrigerating sheet (11) does not generate heat at the moment, and starts to refrigerate, so that the injection molding piece can be cooled, the injection molding piece molding is accelerated, and the working efficiency is improved;
s4, firstly, the air rod (7) is used for opening and closing the mold, when the injection molding part is molded, the air rod (7) can push the female mold (3) to separate the male mold (2) from the female mold (3), and then the ejector rod (8) is used for ejecting the molded injection molding part under the action of the ejector plate;
s5, at the moment, the male die (2) and the female die (3) are separated, so that the supporting rod (53) is driven to move through the fixed seat (56), and then the pull rod (54) pushes the arc plate (55) upwards through the rotation of the turntable (52), so that the arc plate (55) rotates by taking the middle point of the arc plate (55) as the center;
