[0056] The screw 10 is slidably mounted in the through hole 8, and the lower end is threadedly connected to the internal threaded sleeve 9;

[0057] The rotation of the internal threaded sleeve 9 can drive the screw 10 to slide upward in the through hole 8, so as to lift the die-cast parts and eject them from the lower module 5, making it convenient for the staff to collect them;

[0058] A limiting groove 11 is formed on the inner wall surface of the through hole 8;

[0059] The limiting block 12 is fixedly mounted on the outer surface of the screw rod 10 and is slidably connected to the limiting groove 11;

[0060] When the screw rod 10 slides in the through hole 8, it can drive the limit block 12 to slide in the limit groove 11. The limit groove 11 and the limit block 12 can limit the screw rod 10 to prevent it from rotating.

[0061] The driving mechanism is arranged in the groove 7 and is used for driving a pair of internal threaded sleeves 9 to rotate.

[0062] Specifically, the driving mechanism includes:

[0063] The worm gear 13 is fixedly mounted on the outer surface of the internal thread sleeve 9;

[0064] The worm 14 is rotatably mounted in the groove 7 and is meshedly connected with a pair of worm wheels 13 respectively;

[0067] The chain 17 is also meshed and connected with a pair of sprocket wheels 16;

[0068] The driving member 15 is a three-phase motor, and the rotation of its output end can drive a sprocket 16 to rotate. At this time, under the action of the chain 17, another sprocket 16 can drive the worm 14 to rotate at the same time. At this time, the rotation of the worm 14 can respectively drive a pair of worm wheels 13 to rotate at the same time, so that the pair of worm wheels 13 can respectively drive a pair of internal threaded sleeves 9 to rotate at the same time.

[0069] Specifically, a first annular water channel 18 is formed in the lower module 5, and a second annular water channel 19 is formed in the lower module 5 and below the first annular water channel 18;

[0070] A water inlet 20 communicating with the first annular water channel 18 is formed in one side wall of the lower module 5;

[0073] The staff injects the coolant into the first annular water channel 18 from the water inlet 20. At this time, the coolant flows in the first annular water channel 18, flows into the second annular water channel 19 from the connecting hole 22, and then flows out from the water outlet 21, so that the coolant in the first annular water channel 18 and the second annular water channel 19 can cool down the lower module 5, and the die-cast parts in the lower module 5 are cooled at the same time.

[0074] Specifically, a hydraulic cylinder 23 is fixedly mounted on the lower end surface of the top plate 2, and the telescopic end of the hydraulic cylinder 23 is fixedly connected to the upper end surface of the upper module 6;

[0075] The telescopic end of the hydraulic cylinder 23 is extended to drive the upper die block 6 to descend, so that it merges with the lower die block 5 to die-cast the raw material.

[0076] Specifically, a pair of side plates 3 are formed with slide grooves 24 on their end surfaces close to each other, and a slider 25 slidably connected to the slide grooves 24 is fixedly mounted on the outer wall surface of the upper module 6;

[0077] Under the action of the slide groove 24 and the slider 25, the upper module 6 can be made more stable when descending or ascending.

[0078] Working principle: First, the staff places the raw material on the lower module 5. At this time, the staff starts the hydraulic cylinder 23. The extension of the telescopic end of the hydraulic cylinder 23 can drive the upper module 6 to move downward, and cooperate with the lower module 5 to die-cast the raw material into parts. After the die-casting is completed, the staff controls the telescopic end of the hydraulic cylinder 23 to contract, so that the upper module 6 moves upward, and at the same time, the external coolant is injected into the first annular water channel 18 from the water inlet 20. When the coolant fills the first annular water channel 18, it will flow into the first annular water channel 19 through the connecting hole 22. When the coolant fills the second annular water channel 19, it will flow out from the water outlet 21. At this time, the coolant flowing in the first annular water channel 18 and the second annular water channel 19 can cool down the lower module 5 and the parts at the same time. After cooling is completed, The staff starts the driving member 15, and the rotation of its output end can drive a sprocket 16 to rotate. At this time, under the action of the chain 17, another sprocket 16 can drive the worm 14 to rotate at the same time. At this time, the rotation of the worm 14 can respectively drive a pair of worm wheels 13 to rotate at the same time, so that the pair of worm wheels 13 can respectively drive a pair of internal threaded sleeves 9 to rotate at the same time. The rotation of the pair of internal threaded sleeves 9 can respectively drive a pair of screws 10 to slide upward in a pair of through holes 8, so that the die-cast parts can be lifted up and ejected from the lower module 5, which is convenient for the staff to collect. At the same time, when the screw 10 slides in the through hole 8, it can drive the limit block 12 to slide in the limit groove 11. The limit groove 11 and the limit block 12 can limit the screw 10 to prevent it from rotating, which brings convenience to people.
