9. The plastic injection molding machine with a safety door protection device according to claim 1, wherein the protection method of the injection molding machine comprises the following specific steps:
s1, when the work is started, when the equipment is ready to work, the safety door (1) is closed, the safety door (1) moves rightwards, when the safety door (1) moves rightwards, the corresponding safety door (1) also moves leftwards, the anti-elastic block (6) is inserted into the hole (8), when the force used for closing the door is too large, the anti-elastic block (6) pushes the stress plate (51) leftwards, the stress plate (51) moves leftwards, the reset spring (52) is pushed, the reset spring (52) is stressed to contract, and when the stress plate (51) moves leftwards, the driving rod (54) is driven to move leftwards through the pull rod (53);
s2, when the driving rod (54) moves leftwards, the convex block at the bottom of the driving rod (54) has downward thrust on the control rod (55), so that the control rod (55) moves downwards, and therefore has thrust on the limiting spring (56), and simultaneously resists the friction force of the delay block (57), when the control rod (55) moves downwards, the control rod enters the hole (8), when the anti-bounce block (6) moves leftwards, and when rebounding is caused by too large force path, the anti-bounce block (6) is clamped by the bottom of the control rod (55), so that the anti-bounce block (6) moves rightwards, and the safety door (1) is limited to slide towards two sides, so that the effect of rebounding caused by too large force path is achieved when the safety door is closed;
s3, when the safety door (1) moves rightwards, the connecting block (21) drives the ejector block (22) to also move rightwards, so that when the ejector block (22) moves rightwards, upward thrust is firstly applied to the moving block (23), the moving block (23) drives the movable rod (24) to move upwards together, the top of the movable rod (24) is separated from clamping inside the safety lock (25), at the moment, the ejector block (22) moves to the right end of the moving block (23), and meanwhile, the movable rod (24) is not clamped by the safety lock (25) any more, so that when moving downwards, the movable block (23) is driven to also move downwards;
s4, the limit of the moving block (23) is released, so that the energy-gathered spring (32) is pulled by the guide post (31) and the connecting rod (26) to move rightwards, and the pushing force is applied to the top block (22), so that the top block (22) is pushed to move rightwards, and the situation that the safety door is not closed tightly enough when closed is avoided, so that a safety circuit of the safety door is not connected and equipment does not work, and the effects that when the safety door is closed too lightly, the safety door is not closed tightly, the safety door is automatically closed, the circuit is prevented from being disconnected and the equipment does not work are achieved;
s5, move rightwards along with guide pillar (31) simultaneously, drive push rod (34) and move rightwards together, thereby there is an impetus to compression spring (35), make compression spring (35) inside atress compress, simultaneously when push rod (34) move rightwards, drive spin (42) through accepting pole (41) and move rightwards together, thereby there is an impetus to pressure pole (43), because of pressure pole (43) are the tilt state, thereby when spin (42) promote, make pressure pole (43) upper end move upwards, thereby there is an extrusion force to lubricated oil pocket (45), make the inside lubricating oil extrusion of lubricated oil pocket (45) go out, through the relation of connection of internal pipeline, thereby it makes clearance department to transport emergency exit (1) slip, thereby reach when the emergency exit slides, from smearing lubricating oil, reduce the effect of sliding friction.
