The limiting block 54 is square in shape, providing a basis for the movement of the mold core 4. The locking assembly 55 includes a mounting groove 551, a rotating shaft 552, a locking block 553, and a locking groove 554. The mounting groove 551 is opened in the middle of the interior of the base 1. The rotating shaft 552 is rotatably connected to the middle of the interior of the mounting groove 551. The locking block 553 is set on the upper end of the outer surface of the rotating shaft 552. Mold core 4 The lower end of the mold core 4 has longitudinally distributed clearance openings, which are vertically adjacent to the locking block 553. Locking grooves 554 are all located inside the lower end of the mold core 4. The outer surface of the locking block 553 is fitted with the inner wall of the locking groove 554, and the outer surface of the locking block 553 is slidably connected to the inner wall of the locking groove 554, providing a basis for fixing and releasing the mold core 4. The locking assembly 55 also includes a worm gear 555, a worm 556, and a knob 557. The worm gear 555 is located at the lower end of the outer surface of the rotating shaft 552, and the worm 556 is rotatably connected to the mounting groove 551. On the rear side, the worm gear 555 meshes with the worm 556, and the knob 557 is located on the right side of the worm 556, providing a stable drive for fixing and releasing the mold core 4. The locking assembly 55 also includes an arrow mark 558, which is located in the middle of the right side of the knob 557, providing a mark for fixing and releasing the mold core 4.

It can quickly produce the bearing housing, reduce the number of hydraulic push rods, and thus reduce the operation and maintenance cost of the equipment.

[0024] The working principle of the locomotive axle box casting mold provided by this utility model is as follows: When casting the locomotive axle box shell, an external hydraulic push rod is connected through the connecting flange 7. At this time, the various mold blocks are in a separated state. The telescopic end of the external hydraulic push rod moves downward, driving the upper module 3 and the mold core 4 to move downward synchronously until the lower end of the mold core 4 is inserted into the outer surface of the insert post. The longitudinally distributed clearance openings are locking blocks 553. By clearing the clearance, the knob 557 is rotated 135 degrees clockwise, and the worm gear 556 also rotates accordingly, driving the worm wheel 555 to rotate. As the worm wheel 555 rotates, the worm wheel 556 rotates. As 5 rotates, the rotating shaft 552 and locking block 553 also rotate synchronously. Locking block 553 deflects and enters the locking groove 554, creating a limiting effect on the mold core 4. As the extension end of the external hydraulic push rod continues to move downward, the mold core 4 remains stationary, and the upper module 3 continues to move downward. The upper end of the limiting block 54 leaves the top wall of the mold core 4. At this time, the limiting post 52 enters the limiting groove 51 from the upper end. As the upper module 3 continues to move downward, the limiting post 52 presses against the corresponding limiting groove 51, causing the two outer modules 2 to move inward synchronously. When the two outer modules 2 are attached together, the lower end of the limiting block 54 also contacts the bottom wall of the mold core 4. At this time, the top wall of the upper module 3 is also attached to the upper ends of the mold core 4 and the outer module 2. The base 1, outer module 2, upper module 3 and mold core 4 form a housing mold for the bearing box. Then, high-temperature liquid metal is injected into the housing mold from the inclined gate 6. After cooling, the telescopic end of the external hydraulic push rod moves upward. The upper module 3, connecting column 53 and limiting block 54 move upward first. After the upper module 3 is demolded, the limiting column 52 squeezes the limiting groove 51. The two outer modules 2 move outward synchronously to complete the demolding of the outer modules 2. Then, the knob 557 is reversed 135 degrees so that the arrow mark 558 is pointing upward. At this time, through the meshing of the worm gear 555 and worm 556 and the transmission of the rotating shaft 552, the locking block 553 returns to its original position and is vertically adjacent to the clearance opening. The mold core 4 loses its limiting effect. At this time, the upper end of the limiting block 54 just contacts the top wall of the mold core 4. As the upper module 3 continues to move upward, the mold core 4 also moves upward until the mold core separates from the housing, completing the casting of the bearing housing.
