7. The method of using a wax melting device for wax mold casting according to claim 5, wherein: the method comprises the following steps:
s1: when a user melts the wax blocks, the wax blocks are firstly placed in a feed pipe of a wax melting cylinder (1), then the wax blocks are primarily crushed through a grinding mill (5), then a telescopic cylinder (2) stretches and is matched with a spring telescopic rod (35) to drive a pressing cylinder (34) to move downwards in an outer cylinder (39), so that a pull rod (37) deflects to push a pressing knife (38) to deflect and spread and then to prop against the upper end face of a clamping ring (311), the pressing knife (38) can not continuously deflect, at the moment, the outer cylinder (39) drives an outer spiral groove pipe (313) to move downwards on the inner side of a sealing ring plate (41), a limiting force is applied to an outer spiral groove on the surface of the outer spiral groove pipe (313) through the end part of a spring clamping rod (43), the outer spiral groove pipe (313) is driven to rotate clockwise to drive a spring (314) to wind up, and when the outer cylinder (39) moves downwards to the bottom face of the inner wall of the wax melting cylinder (1), the bottom face of the inner wall of the wax blocks on the inner wall of the wax melting cylinder (1) is crushed through the cooperation of the bottom face of the outer cylinder (39) and the pressing knife (38);
when the outer cylinder (39) is abutted against the bottom surface of the inner wall of the wax melting cylinder (1), the round rod (31) continuously moves downwards to extrude the spring telescopic rod (35) to shrink, at the moment, the lower fluted disc (32) on the round rod (31) is separated from the upper fluted disc (33), so that the spring (314) is promoted to release the winding force and drive the outer cylinder (39) to rotate, and wax blocks on the bottom surface of the inner wall of the wax melting cylinder (1) are stirred;
s2: then when the telescopic cylinder (2) is contracted and reset, the lower fluted disc (32) and the upper fluted disc (33) are clamped together under the action of the spring telescopic rod (35), the resistance between the spring clamping rod (43) and the outer spiral groove on the surface of the outer spiral groove pipe (313) enables the pulling pull rod (37) to deflect and fit in the vertical groove (36), the pulling pressing knife (38) to deflect and abut in the L-shaped through groove (310), then the outer barrel (39) and the outer spiral groove pipe (313) are driven to move upwards, at the moment, the outer spiral groove on the outer side of the outer spiral groove pipe (313) pushes the spring clamping rod (43) to rotate along with the inner ring of the one-way bearing (42), and a user reciprocates so as to crush and stir the crushed wax blocks again;
s3: when a user melts the wax block, the outer cylinder (39) is pulled to move upwards through shrinkage of the telescopic cylinder (2), at the moment, one end of the spring clamping rod (43) is separated from the outer spiral groove on the surface of the outer spiral groove pipe (313) and is abutted against the outer side of the outer cylinder (39), at the moment, the clamping ring (311) on the outer cylinder (39) moves into the annular groove (46), then the user rotates the rotating handle (410) to drive one gear (48) to rotate so as to push the gear ring (411) to rotate, and simultaneously one end of the three rest toothed plates (45) is driven to move out of the annular groove (47), the other end of the toothed plates (45) is inserted into the limiting groove on the outer side of the clamping ring (311), at the moment, the outer cylinder (39) and the sealing ring plate (41) form a whole, and then the sealing ring plate (41) and the outer cylinder (39) are driven to move downwards through the telescopic cylinder (2), so that wax liquid in the wax cylinder (1) is discharged.
