Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a gate that can improve the life of die-casting molds. Background Technology

[0002] Die casting molds are tools used to cast metal parts. The basic process of die casting involves the molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools, eliminating shrinkage cavities and porosity defects in the blank and allowing the internal structure of the blank to reach the forged state with broken grains.

[0003] However, when using existing die-casting mold gates, the molten metal is quickly filled and compacted into the casting under high pressure. However, when the temperature at the gate is too high, it will slow down the solidification rate of the molten metal, making it easy for micropores to form inside the casting. At the same time, it will lead to a decrease in the performance of the mold, making it prone to thermal cracks and deformation, which will have a certain impact on the service life of the mold. Therefore, a gate that can improve the service life of die-casting molds needs to be designed. Utility Model Content

[0004] In view of the problems in the background art, this utility model provides a gate that can improve the service life of die casting molds.

[0005] The technical solution adopted by this utility model to solve its technical problem is a gate that can improve the service life of die-casting molds. It includes a die-casting mold body, with a gate inside the die-casting mold body. A thermocouple sensor for detecting the gate temperature is screwed onto the outside of the gate. A cooling component for cooling the gate is installed inside the die-casting mold body. A buffer component for reducing cooling water impact is installed inside the cooling component. A water inlet pipe is inserted into the top of the die-casting mold body, and a valve is screwed onto the end of the water inlet pipe. A branch pipe is screwed onto the end of the valve away from the water inlet pipe. A water outlet pipe is inserted into the bottom of the die-casting mold body. A controller for controlling the valve is screwed onto the outside of the die-casting mold body.

[0006] By adopting the above technical solution, when the thermocouple sensor outside the gate detects that the temperature of the gate exceeds the set value, the thermocouple sensor transmits the signal to the controller outside the die-casting mold body. Then the controller opens the valve switch, and then the cooling water is transported through the branch pipe to the cooling component inside the die-casting mold body, which facilitates the cooling treatment of the gate, facilitates the protection of the gate, and improves the service life of the die-casting mold body.

[0007] Specifically, the cooling assembly includes an outer cavity, an inner cavity, an arc plate, a through hole, a fixing hole, and a support block. A heat-conducting layer is provided on the outside of the gate, and an inner cavity is provided on the outside of the heat-conducting layer. An outer cavity is integrally formed outside the inner cavity. A support block is welded to the top of the inner cavity. Through holes are symmetrically opened at the top of the inner cavity, and fixing holes are opened at the bottom of the inner cavity.

[0008] By adopting the above technical solution, when the inlet pipe delivers cooling water to the outer cavity, the symmetrically installed support blocks in the outer cavity block the cooling water, allowing the cooling water to enter the inner cavity through the symmetrically opened through holes on the inner cavity. At the same time, the heat-conducting layer outside the gate is made of graphene coating, which transfers the heat of the gate to the inner cavity. Subsequently, the cooling water in the inner cavity absorbs the heat, and then the heat-absorbing cooling water is discharged into the outer cavity through the fixed hole opened at the bottom of the inner cavity. Then, the water outlet pipe installed at the bottom of the outer cavity discharges the cooling water, thereby facilitating the cooling treatment of the gate.

[0009] Specifically, an arc plate is integrally formed at the bottom of the inner cavity of the outer cavity.

[0010] By adopting the above technical solution, when the cooling water in the inner cavity is discharged through the fixed hole, the arc plate in the outer cavity prolongs the time of the cooling water in the outer cavity, so that the cooling water can fully cool the gate and improve the utilization rate of the cooling water.

[0011] Specifically, the buffer assembly includes an arc block and a rubber pad. The arc block is integrally formed inside the outer cavity, and the rubber pad is fixed to the outside of the arc block by screws.

[0012] By adopting the above technical solution, when cooling water enters the outer cavity through the inlet pipe, the cooling water comes into contact with the arc block inside the outer cavity. The arc block diverts the cooling water, and at the same time, the rubber pad installed outside the arc block is elastic, which buffers the downward impact force of the cooling water and reduces the impact force of the cooling water entering the outer cavity.

[0013] Specifically, the input terminals of the thermocouple sensor, valve, and controller are all electrically connected to the power supply terminal of an external power source.

[0014] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0015] The beneficial effects of this utility model are:

[0016] (1) The gate described in this utility model can improve the service life of the die casting mold. When the thermocouple sensor outside the gate detects that the temperature of the gate exceeds the set value, the thermocouple sensor transmits the signal to the controller outside the die casting mold body. Then the controller opens the valve switch, and then the cooling water is delivered to one end of the water inlet pipe through the branch pipe and extends into the outer cavity. Then the cooling water enters the outer cavity. The support blocks installed symmetrically in the outer cavity block the cooling water, so that the cooling water enters the inner cavity through the through holes symmetrically opened on the inner cavity. At the same time, the heat-conducting layer outside the gate is made of graphene coating, which transfers the heat of the gate to the inner cavity. Then the cooling water in the inner cavity absorbs the heat. Then the cooling water that has absorbed the heat is discharged into the outer cavity through the fixing hole opened at the bottom of the inner cavity. Then the water outlet pipe installed at the bottom of the outer cavity discharges the cooling water, thereby facilitating the cooling treatment of the gate and improving the service life of the die casting mold body.

[0017] (2) The gate of this utility model can improve the service life of the die casting mold. When the cooling water enters the outer cavity through the water inlet pipe, the cooling water comes into contact with the arc block in the outer cavity. The arc block will process the cooling water by flow. At the same time, the rubber pad installed outside the arc block is elastic and buffers the downward impact force of the cooling water, reducing the impact force of the cooling water entering the outer cavity.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] In order to improve the service life of the die-casting mold body 6, as an embodiment of this utility model, such as Figures 1 to 2As shown, the present invention provides a gate for improving the life of a die-casting mold, comprising a die-casting mold body 6, a gate 15 disposed inside the die-casting mold body 6, a thermocouple sensor 14 for detecting the temperature of the gate 15 fixed to the outside of the gate 15 by screws, a cooling component 18 for cooling the gate 15 disposed inside the die-casting mold body 6, a buffer component 19 for reducing the impact of cooling water disposed inside the cooling component 18, a water inlet pipe 3 inserted into the top of the die-casting mold body 6, and a valve 2 fixed to the end of the water inlet pipe 3 by screws, a branch pipe 1 fixed to the end of the valve 2 away from the water inlet pipe 3 by screws, a water outlet pipe 5 inserted into the bottom of the die-casting mold body 6, and a controller 4 for controlling the valve 2 fixed to the outside of the die-casting mold body 6 by screws.

[0024] When in use, when the thermocouple sensor 14 outside the gate 15 detects that the temperature of the gate 15 exceeds the set value, the thermocouple sensor 14 transmits the signal to the controller 4 outside the die-casting mold body 6. Then the controller 4 opens the valve 2 switch, and then the cooling water is transported through the branch pipe 1 to the cooling component 18 inside the die-casting mold body 6, which facilitates the cooling treatment of the gate 15, facilitates the protection of the gate 15, and improves the service life of the die-casting mold body 6.

[0025] To cool down gate 15, for example, such as Figure 2 As shown, the present invention also includes the following: the cooling assembly 18 includes an outer cavity 9, an inner cavity 13, an arc plate 10, a through hole 8, a fixing hole 17, and a support block 7. A heat-conducting layer 16 is provided on the outside of the gate 15, and an inner cavity 13 is provided on the outside of the heat-conducting layer 16. The outer cavity 9 is integrally formed on the outside of the inner cavity 13. The support block 7 is welded to the top of the inner cavity 9. Through holes 8 are symmetrically opened on the top of the inner cavity 13, and fixing holes 17 are opened on the bottom of the inner cavity 13.

[0026] In use, when the inlet pipe delivers cooling water into the outer cavity 9, the symmetrically installed support blocks 7 in the outer cavity 9 block the cooling water, allowing the cooling water to enter the inner cavity 13 through the symmetrically opened through holes 8 on the inner cavity 13. At the same time, the heat-conducting layer 16 outside the gate 15 is made of graphene coating, which transfers the heat of the gate 15 to the inner cavity 13. Then, the cooling water in the inner cavity 13 absorbs the heat, and the heat-absorbing cooling water is discharged into the outer cavity 9 through the fixing hole 17 opened at the bottom of the inner cavity 13. Then, the water outlet pipe 5 installed at the bottom of the outer cavity 9 discharges the cooling water, thereby facilitating the cooling treatment of the gate 15.

[0027] To improve the utilization rate of cooling water, for example, such as Figure 2 As shown, the present invention also includes an arc plate 10 integrally formed at the bottom of the inner cavity 9.

[0028] When in use, when the cooling water in the inner cavity 13 is discharged through the fixing hole 17, the arc plate 10 in the outer cavity 9 prolongs the time that the cooling water stays in the outer cavity 9, so that the cooling water can fully cool the gate 15 and improve the utilization rate of the cooling water.

[0029] To reduce the impact force of cooling water entering the outer cavity 9, for example, such as Figure 2 As shown, the present invention also includes the buffer assembly 19 comprising an arc block 12 and a rubber pad 11. The arc block 12 is integrally formed inside the outer cavity 9, and the rubber pad 11 is fixed to the outside of the arc block 12 by screws.

[0030] When in use, when cooling water enters the outer cavity 9 through the inlet pipe 3, the cooling water comes into contact with the arc block 12 inside the outer cavity 9. The arc block 12 diverts the cooling water. At the same time, the rubber pad 11 installed outside the arc block 12 is elastic and buffers the downward impact force of the cooling water, reducing the impact force of the cooling water entering the outer cavity 9.

[0031] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 As shown, this utility model also includes the fact that the input terminals of the thermocouple sensor 14, valve 2 and controller 4 are all electrically connected to the power supply terminal of an external power source.

[0032] When in use, the electrical equipment works normally by connecting to an external power source.

[0033] In use, the branch pipe 1 is first connected to the external cooling water tank, and then the outlet pipe 5 is connected to the collection box. When the thermocouple sensor 14 outside the gate 15 detects that the temperature of the gate 15 exceeds the set value, the thermocouple sensor 14 transmits the signal to the controller 4 outside the die-casting mold body 6. Then the controller 4 opens the valve 2 switch, and then the cooling water is delivered through the branch pipe 1 to the inlet pipe 3 on one side of the valve 2. One end of the inlet pipe 3 extends into the outer cavity 9, and then the cooling water enters the outer cavity 9. The cooling water contacts the arc block 12 inside the outer cavity 9, and the arc block 12 diverts the cooling water. At the same time, the rubber pad 11 installed outside the arc block 12 is elastic and buffers the downward impact force of the cooling water, reducing the impact force of the cooling water entering the outer cavity 9. The symmetrically installed support blocks 7 in the outer cavity 9 block the cooling water, so that the cooling water passes through the symmetrical openings on the inner cavity 13. The heat is transferred from the through hole 8 into the inner cavity 13. Meanwhile, the heat-conducting layer 16 outside the gate 15 is made of graphene coating, which transfers the heat of the gate 15 to the inner cavity 13. Then, the cooling water in the inner cavity 13 absorbs the heat. The cooling water that has absorbed the heat is then discharged into the outer cavity 9 through the fixing hole 17 opened at the bottom of the inner cavity 13. The arc plate 10 in the outer cavity 9 prolongs the time that the cooling water stays in the outer cavity 9, so that the cooling water can fully cool the gate 15 and improve the utilization rate of the cooling water. Then, the water outlet pipe 5 installed at the bottom of the outer cavity 9 discharges the cooling water, which facilitates the cooling treatment of the gate 15 and improves the service life of the die-casting mold body 6. When the thermocouple sensor 14 outside the gate 15 detects that the temperature of the gate 15 is lower than the set value, the thermocouple sensor 14 transmits the signal to the controller 4. The controller 4 closes the valve 2, so that the cooling water stops being delivered to the die-casting mold body 6.
