7. The precision mold sealing performance testing equipment according to claim 6, characterized in that: The top of the base plate (1) is fixedly connected to a drive box (4), the bottom of the inner cavity of the drive box (4) is rotatably connected to a rotating shaft (8), the top of the rotating shaft (8) extends to the top of the drive box (4) and is fixedly connected to the top plate (9), the bottom of the top plate (9) is slidably connected to a moving column (12), one side of the moving column (12) is fixedly connected to a guide rail (13), the top of the guide rail (13) is fixedly connected to a second servo motor (15), the inner cavity of the guide rail (13) is rotatably connected to a first threaded rod (14), the top of the second servo motor (15) is fixedly connected to the bottom end of the first threaded rod (14), the outer side of the first threaded rod (14) is threadedly connected to a connecting piece (16), one end of the connecting piece (16) extends to the outside of the guide rail (13) and extends into the interior of the detection cavity (3), and a side groove (17) is provided on one side of the connecting piece (16).

8. The precision mold sealing performance testing equipment according to claim 7, characterized in that: The method for testing the sealing performance of a mold using the precision mold sealing performance testing equipment comprises the following steps: Step 1: Place the mold on top of the fixed platform (26), then the telescopic end of the second electric telescopic rod (34) pushes the clamping block (35) to move, so that the two clamping blocks (35) clamp the mold, and then the output end of the second servo motor (15) drives the first threaded rod (14) to rotate, so that the first threaded rod (14) drives the connecting piece (16) and the fixed platform (26) to drive the mold to move down to the inside of the detection chamber (3). Step 2: Then the telescopic end of the first electric telescopic rod (18) pushes the vibration box (20) through the side groove (17) to move to the appropriate position, and then the output end of the fourth servo motor (56) drives the transmission shaft (37) to rotate, so that the transmission shaft (37) drives the cam (38) to rotate. When the convex end of the cam (38) rotates toward the striking column (39), one end of the striking column (39) strikes the bottom of the mold, and the striking column (39) drives the piston column (43) upward, so that the piston column (43) discharges the liquid inside the piston cylinder (41) through the pipe (44) and the first hose (25) into the liquid bag (24), so that the liquid bag (24) expands and pushes the push block ( 21) and the top column (22) move, so that the top column (22) hits the outside of the mold. When the circular end of the cam (38) rotates toward the hitting column (39), the second spring (40) pushes the hitting column (39) downward, so that the hitting column (39) drives the piston column (43) downward, so that the liquid inside the liquid bag (24) is sucked into the inside of the piston cylinder (41) through the first hose (25) and the pipe (44), so that the liquid bag (24) shrinks. At this time, the first spring (23) pushes the push block (21) to drive the top column (22) to reset and move, so that the mold is struck, so that the bubbles inside the mold are discharged, and the mold is filled with water. Then the mold is lifted to observe whether there is leakage.
