[0002] A cold chamber die-casting machine is a die-casting machine in which the injection chamber and the injection punch are not immersed in the molten metal, but a certain amount of molten metal is poured into the injection chamber and then injection is performed. The injection method of the vertical cold chamber die-casting machine is placed vertically, which obviously follows the injection method of the hot die-casting machine.

[0003] In the prior art, a Chinese patent document with publication number CN107838394A proposes a cold chamber die-casting machine, which solves the problem that the existing cold die-casting machine uses natural cooling to cool the casting, which takes too long and slows down the manufacturing speed of the casting. After die-casting, the worker needs to go deep into the mold to take out the casting.

[0015] Compared with the prior art, the present invention provides a cold chamber die casting machine, which has the following beneficial effects: 1. The cold chamber die-casting machine can drive the movable mold to move through the first hydraulic rod, and when the movable mold moves, it will drive the second hydraulic rod to move together, so that the second hydraulic rod can push the cooled casting to move out of the movable mold. After the casting is formed, the water pump is started to extract the cooling water in the water tank and input it into the first water pipe through the second water pipe to absorb heat, and then it is discharged through the third water pipe to circulate the cooling water for cooling, so that the cooling effect is better.

The second baffle blocks debris from entering the heat sink, and blocks splashing cooling water from splashing to the outside of the heat sink through the second baffle. When the cooling water is cooled by the fan, the cooling water will fly to the front of the fan, be blocked by the heat sink, and then fall into the heat sink, thereby reducing the occurrence of cooling water splashing to the heat sink through the heat dissipation holes. After absorbing the heat of the casting, the cooling water is cooled in the heat sink and then falls into the water tank for the next cooling, thereby ensuring a better cyclic cooling effect.

The heat dissipated by the cooling water can escape from the heat sink 10 and the water tank 9 through the heat dissipation holes 19, thereby improving the cooling effect of the cooling water. The second baffle 20 blocks debris from entering the heat sink 10, and blocks the splashing cooling water from splashing to the outside of the heat sink 10 through the second baffle 20. When the cooling water is cooled by the fan 12, the cooling water will fly to the front of the fan 12, be blocked by the heat sink 10, and then fall into the heat sink 10, thereby reducing the occurrence of cooling water splashing to the heat sink 10 through the heat dissipation holes 19. After absorbing the heat of the casting, the cooling water is cooled in the heat sink 10 and then falls into the water tank 9 for the next cooling, thereby ensuring a better circulation cooling effect.

[0028] The user pushes the first baffle 18 to rotate upward to open the connecting hole 17, and then sends the shower head 16 into the heat dissipation box 10, and then sends the connecting block 15 into the first connecting groove 14 and pushes it along the first connecting groove 14 to the lower end of the third water pipe 11, so that the cooling water flowing out of the third water pipe 11 is discharged through the shower head 16, so that the cooling water is dispersed and cooled, and the cooling effect of the fan 12 on the cooling water is enhanced, so as to ensure that the cooling effect of the cooling water is better during long-term circulation cooling, and the connecting block 15 is easy to connect with the first connecting groove 14. The first connecting groove 14 limits the position of the connecting block 15 through the T-shaped groove, so as to fix the position of the shower head 16, ensure the normal use of the shower head 16, and make the shower head 16 easy to disassemble, so that the user can clean the shower head 16 conveniently, and avoid the debris in the cooling water blocking the water outlet of the shower head 16 after long-term use, which affects the use of the shower head 16, and is conducive to the long-term use of the device.

[0029] The rotation direction of the guide plate 21 is limited by the support frame 1, and the position of the spring telescopic rod 22 is fixed by the support frame 1. The guide plate 21 can be pushed to rotate upward by the spring telescopic rod 22. When the movable mold 3 moves, the pressing plate 23 will be driven to move together. The movable mold 3 can be supported by the moving wheel 24, so that the movement of the movable mold 3 is more stable. When the movable mold 3 moves in the direction close to the fixed mold 26, the pressing plate 23 will be released from the guide plate 21 before the moving wheel 24. In the process of the movable mold 3 driving the pressing plate 23 to move, the pressing plate 23 will gradually press the guide plate 21 downward, so that the moving wheel 24 can move to the guide plate 21. The top of the plate 21 does not affect the movement of the movable mold 3. After the guide plate 21 is pressed down by the pressure plate 23, it does not affect the movement of the moving wheel 24. After the guide plate 21 loses the effect of the pressure plate 23, it will move driven by the spring telescopic rod 22, so that the top of the guide plate 21 forms a slope, so that the casting pushed out of the movable mold 3 is guided by the guide plate 21 to slide to one side for collection after falling to the top surface of the guide plate 21, thereby avoiding the operation of manually taking the casting from between the movable mold 3 and the fixed mold 26, thereby avoiding the situation where the staff is burned by the casting or the movable mold 3 and the fixed mold 26.
