Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a cooling mechanism for a die-casting machine. Background Art

[0002] A die-casting machine is a machine used for pressure casting. In the field of electronic equipment, die-casting machines are used to die-cast metal video boxes. Metal materials, such as aluminum alloys, have high strength and hardness, and can withstand external forces such as collisions and extrusions in daily use, ensuring that the electronic components inside the video box are well protected. The die-casting machine uses pressure to hydraulically inject molten metal into the mold and cool it to form a solid metal casting. During the die-casting process, the molten metal is injected into the mold under high temperature and high pressure and solidifies rapidly. During this process, the mold and the die-casting will absorb a lot of heat, causing the temperature to rise.

[0003] During the cooling process of the mold and casting, it is generally cooled by extending the die-casting cycle, spraying mold release agents or coolants, but extending the die-casting cycle will cause the casting to continue to be high in temperature and have low efficiency. Therefore, when the metal liquid in the mold solidifies rapidly, opening the mold and spraying a mold release agent or coolant inside becomes an effective cooling method. The coolant forms a thin film on the inner wall of the mold, and absorbs the heat on the mold surface through heat exchange. When the operator sprays the coolant, the coolant is sprayed out after being pressurized, which can easily cause the coolant to splash everywhere, which is harmful to the health of the operator. If the spraying equipment is used improperly or the operator is unskilled, the mold release agent or coolant may be sprayed unevenly on the inner wall of the mold, which will affect the cooling effect and even cause inconsistent surface quality of the casting. Utility Model Content

[0007] A die-casting machine body, wherein the die-casting machine body is symmetrically provided with slide bars, wherein the outer surfaces of the slide bars are slidably connected with a mold 1 and a mold 2, wherein the mold 1 and the mold 2 are provided with a telescopic mechanism and a reciprocating swing mechanism, wherein the telescopic mechanism includes a driving component and a cooling component;

[0008] The telescopic mechanism automatically extends into the cooling assembly when the mold 1 and the mold 2 are opened, and automatically retracts into the cooling assembly when the mold 1 and the mold 2 are closed;

[0014] Preferably, the fan gear is rotatably connected to the counterweight block via an axle pin, the circular gear is meshed with the fan gear, a slide groove is provided through the fan gear, and a slider is slidably connected in the slide groove.

[0015] Preferably, the reciprocating swing mechanism further comprises a rotating block, the rotating block is rotatably connected to the connecting rod 1 and the connecting rod 2, and a screw is arranged at the bottom of the rotating block.

This comprehensive coverage reduces the local overheating caused by the spray blind area, thereby improving the overall cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 1-Figure 3 , a die casting machine cooling mechanism, comprising:

[0035] A die-casting machine body 1, on which a slide bar 101 is symmetrically arranged, and a mold 102 and a mold 2 103 are slidably connected on the outer surface of the slide bar 101, and a telescopic mechanism and a reciprocating swing mechanism are arranged on the mold 102 and the mold 2 103, and the telescopic mechanism includes a driving component and a cooling component; the telescopic mechanism automatically extends into the cooling component when the mold 1 102 and the mold 2 103 are opened, and automatically retracts the cooling component when the mold 1 102 and the mold 2 103 are closed; the reciprocating swing mechanism drives the cooling component to swing back and forth continuously through the driving component.

[0036] Among them, the driving component of the telescopic mechanism includes a fixed block 2, which is symmetrically arranged on mold 1 102 and mold 2 103. The fixed block 2 is connected to connecting rod 1 201 and connecting rod 2 202 through an axle pin. Connecting rod 1 201 and connecting rod 2 202 are penetrated and rotatably connected by a connecting shaft 203. A vertical plate 204 is arranged in the middle of the connecting shaft 203, and a counterweight block 205 is fixedly connected to the outer surface of the vertical plate 204.

[0037] Through the above embodiments, the effect achieved by the utility model is: the connecting rod driving assembly is driven up and down by the opening and closing of mold 1 102 and mold 2 103, and the driving assembly is driven by the power of the machine itself. The direct driving method has high real-time performance and ensures the continuous processing.

[0038] Embodiment 2:

[0039] See also Figure 1-Figure 3 , a die casting machine cooling mechanism, comprising:

[0040] A die-casting machine body 1, on which a slide bar 101 is symmetrically arranged, and a mold 102 and a mold 2 103 are slidably connected on the outer surface of the slide bar 101, and a telescopic mechanism and a reciprocating swing mechanism are arranged on the mold 102 and the mold 2 103, and the telescopic mechanism includes a driving component and a cooling component; the telescopic mechanism automatically extends into the cooling component when the mold 1 102 and the mold 2 103 are opened, and automatically retracts the cooling component when the mold 1 102 and the mold 2 103 are closed; the reciprocating swing mechanism drives the cooling component to swing back and forth continuously through the driving component.

Through instant cooling, the die-casting can reach a processable state more quickly, shortening the production cycle.

[0043] Embodiment three:

[0044] See also Figure 1-Figure 3, a die casting machine cooling mechanism, comprising:

[0045] A die-casting machine body 1, on which a slide bar 101 is symmetrically arranged, and a mold 102 and a mold 2 103 are slidably connected on the outer surface of the slide bar 101, and a telescopic mechanism and a reciprocating swing mechanism are arranged on the mold 102 and the mold 2 103, and the telescopic mechanism includes a driving component and a cooling component; the telescopic mechanism automatically extends into the cooling component when the mold 1 102 and the mold 2 103 are opened, and automatically retracts the cooling component when the mold 1 102 and the mold 2 103 are closed; the reciprocating swing mechanism drives the cooling component to swing back and forth continuously through the driving component.

[0046] The reciprocating swing mechanism includes a circular gear 3 and a fan gear 301, which are symmetrically arranged on the counterweight 205, and the circular gear 3 is fixedly connected to the outer surface of the connecting tube 206. The fan gear 301 is rotatably connected to the counterweight 205 through an axle pin, and the circular gear 3 is meshed with the fan gear 301. A slide groove 302 is provided on the fan gear 301, and a slider 303 is slidably connected in the slide groove 302. The reciprocating swing mechanism also includes a rotating block 304, which is rotatably connected to the connecting rod 1 201 and the connecting rod 2 202, and a screw 305 is provided at the bottom of the rotating block 304.

[0047] Furthermore, the bottom of the screw rod 305 is threadedly connected to the gear 1 306 and penetrates the counterweight 205. The bottom of the gear 1 306 is rotatably connected to the counterweight 205. A gear 2 307 is provided on the side of the gear 1 306 close to the connecting pipe 206. The gear 2 307 is rotatably connected to the counterweight 205 through an axle pin. The gear 2 307 is meshed with the gear 1 306. The top of the gear 2 307 is fixedly connected to the connecting rod 3 308 through an axle pin. The connecting rod 3 308 is rotatably connected to the connecting rod 4 309 through an axle pin. The end of the connecting rod 4 309 away from the connecting rod 3 308 is rotatably connected to the slider 303.

[0048] Through the above embodiments, the effect achieved by the utility model is: when connecting rod 1 201 and connecting rod 202 are opened under the drive of mold 1 102 and mold 2 103, connecting rod 1 201 and connecting rod 2 202 gradually tend to be parallel, and through the continuous rotation of the screw 305 at the bottom of the rotating block 304, the circular gear 3 is driven to reciprocate, thereby prompting the cooling component to swing back and forth to continuously swing and cool the die-casting machine body 1 and the casting.

[0049] Through all the above embodiments, the working principle of the utility model is:

[0050] After the die casting machine body 1 has die-cast the mold, the mold 1 102 and the mold 2 103 on the slide bar 101 continue to move away from each other. At this time, the angle between the connecting rod 1 201 and the connecting rod 2 202 rotatably connected on the fixed block 2 gradually increases. Under the limiting effect of the counterweight block 205, the vertical plate 204 always maintains a vertical state, and then drives the nozzle 207 at the bottom of the connecting pipe 206 to extend into the middle of the mold 1 102 and the mold 2 103. Since the nozzle holes of the nozzle 207 are arranged radially, the coolant can cover a wider area, ensuring that all parts of the mold can be evenly cooled, avoiding the problem of local overheating or uneven cooling. When the mold 1 102 and the mold 2 103 on the slide bar 101 continue to move toward each other, the angle between the connecting rod 1 201 and the connecting rod 2 202 rotatably connected on the fixed block 2 gradually decreases, prompting the cooling component to retract;

[0051] Furthermore, when mold 1 102 and mold 2 103 are opened, the rotating block 304 rotatably connected to the connecting rod 1 201 and the connecting rod 2 202 always remains parallel to the counterweight block 205 under the limiting action of the screw 305, and then the screw 305 continues to move downward. When the screw 305 moves downward, it drives the gear 1 306 to rotate continuously. Since the gear 1 306 is meshed with the gear 2 307, the gear 2 307 rotates synchronously. When the gear 2 307 rotates, the connecting rod 3 308 fixedly connected to the gear 2 307 drives the connecting rod 4 309 to move. Since the slider 303 in the slide groove 302 is rotatably connected to the connecting rod 4 309, the connecting rod 4 309 drives the fan gear 301 to swing back and forth continuously. At the same time, the fan gear 301 drives the connecting pipe 206 fixedly connected to the circular gear 3 to swing continuously, which further increases the cooling liquid spraying area, reduces the cooling blind area, and improves the cooling efficiency. This comprehensive cooling helps to quickly reduce the temperature of the mold and casting. Through more uniform cooling, the thermal stress generated in the mold and casting during rapid temperature changes can be reduced, thereby reducing the risk of mold deformation and casting cracks and improving product quality.
