[0031] A lower mold 1, wherein an upper mold 2 is disposed on the top of the lower mold 1, and a baffle 6 is disposed inside the lower mold 1;

[0032] A reset member 3, the reset member 3 is arranged inside the lower mold 1, one end of the reset member 3 is fixedly connected to a support plate 31, a conveying groove 32 is opened inside the lower mold 1, and joints 33 are fixed on both sides of the lower mold 1;

[0033] A movable groove 4, wherein the movable groove 4 is arranged inside the lower mold 1, and a movable block 41 is slidably connected inside the movable groove 4;

[0034] The sealing groove 5 is arranged inside the lower mold 1 , and a sealing plate 51 is slidably connected inside the sealing groove 5 . Two conveying holes 52 are opened inside the sealing plate 51 .

[0035] The sealing groove 5 is opened inside the lower mold 1 .

[0036] Two joints 33 are installed on one side of the lower mold 1. The two joints 33 are both arranged at one end of the conveying trough 32, and are used to respectively convey hot water and cold water to the inside of the conveying trough 32. A joint 33 is also fixedly installed on the other side of the lower mold 1 and is connected to the other end of the conveying trough 32, and is used to discharge the water inside the conveying trough 32.

[0037] The resetting member 3 comprises a damper, and a resetting spring is sleeved on the surface of the damper.

[0038] The reset member 3 is used to push the support plate 31 to push the product out of the lower mold 1 after the product production is completed, so that the operator can remove it easily.

[0039] A plurality of reset members 3 are fixedly installed inside the lower mold 1 , and one end of each of the reset members 3 is fixedly connected to the bottom of the support plate 31 through a connecting rod.

[0040] One side of the sealing plate 51 is fixedly connected to one side of one end of the reset member 3 through a rectangular rod, so as to drive the sealing plate 51 to move to one side when the reset member 3 contracts.

[0041] The number of the moving grooves 4 and the number of the moving blocks 41 are both two, the two moving grooves 4 are both opened inside the lower mold 1, and the two moving blocks 41 are slidably connected to the inside of the two moving grooves 4 respectively.

[0042] One side of the two moving blocks 41 is fixedly connected to two sides of the support plate 31 respectively.

[0043] The two conveying holes 52 are both opened inside the sealing plate 51 and have different heights.

[0044] The working principle of the die-casting mold for the electric control box of a new energy vehicle provided by the utility model is as follows:

[0045] When in use, after the heat dissipation pipe is mounted on the support plate 31 , the baffle plate 6 is mounted on the support plate 31 , and then the two interfaces of the heat dissipation pipe are sealed.

[0046] When the upper mold 2 is combined with the lower mold 1, when the upper mold 2 moves to one side and contacts the moving block 41, it pushes the two moving blocks 41 to move to one side inside the two moving grooves 4 respectively, thereby pushing the support plate 31 to move to one side while squeezing and contracting the reset member 3.

[0047] When the reset member 3 contracts, it drives the sealing plate 51 to move to one side inside the sealing groove 5, so that the lower water inlet hole 52 on the sealing plate 51 overlaps with the hot water connector 33 on one side of the lower mold 1, and hot water enters the lower mold 1 through the conveying groove 32, thereby preheating the lower mold 1.

[0048] At this time, the lower mold 1 is merged with the upper mold 2. After the solution is die-cast into the interior of the lower mold 1 and the upper mold 2 by the die-casting equipment, the pressure when the solution is pressed into the die-casting equipment drives the support plate 31 to move to one side again while squeezing and contracting the reset part 3, so that the sealing plate 51 moves to one side inside the sealing groove 5, so that the higher water inlet hole 52 on the sealing plate 51 overlaps with the cold water joint 33 on one side of the lower mold 1, and the cold water enters the interior of the lower mold 1 through the conveying groove 32, so as to dissipate heat for the lower mold 1. At the same time, the lower water inlet hole 52 on the sealing plate 51 is staggered with the hot water joint 33 on one side of the lower mold 1, and the sealing plate 51 seals the hot water joint 33.

[0049] When the product inside the lower mold 1 is produced, by opening the upper mold 2, the reset member 3 pushes the support plate 31 to push the product inside the lower mold 1 out, thereby facilitating the operator to remove the product. At the same time, the sealing plate 51 is reset to seal the hot water connector 33 and the cold water connector 33 at the same time.

[0050] Compared with the related art, the die-casting mold for the electric control box of a new energy vehicle provided by the utility model has the following beneficial effects:

[0051] The utility model provides a die-casting mold for an electric control box of a new energy vehicle. When the upper mold 2 is moved and opened, the reset member 3 pushes the support plate 31 to push the molded product out of the lower mold 1, so that the molded product can be easily removed. At the same time, when the upper mold 2 is merged with the lower mold 1, the moving block 41 connected to the support plate 31 is driven to move to one side, so that the reset member 3 is contracted, so that the sealing plate 51 is moved downward to a water inlet hole 52 at a lower position inside and contacts with a joint 33, and then hot water enters through a conveying groove 32 and enters the lower mold 1 for preheating, so as to prevent the solution from solidifying before being fully filled when die-casting into the lower mold 1, affecting the filling effect and reducing the product quality. At the same time, when the pressure generated when the solution enters during die-casting drives the support plate 31 to contract the reset member 3 again, the water inlet hole 52 at a higher position on the sealing plate 51 overlaps with the cold water joint 33, and then enters the lower mold 1 through the conveying groove 32 for heat dissipation, thereby accelerating the molding of the product and increasing the heat dissipation effect.

[0056] The top of the connecting block 73 is fixedly connected to the bottom of the reset block 71 , and the bottom is fixedly connected to the top of the baffle 6 .

[0057] The working principle of the die-casting mold for the electric control box of a new energy vehicle provided by the utility model is as follows:

[0058] When in use, when the upper mold 2 moves to one side, the reset block 71 connected to the connecting block 73 moves to one side, thereby driving the baffle 6 to automatically separate from the lower mold 1.

[0059] When the upper mold 2 moves to one side and drives the baffle 6 to be inserted into the interior of the lower mold 1, when the baffle 6 moves to a suitable position and seals the interface of the heat dissipation tube, the upper mold 2 is still moving to one side, pushing the connecting block 73 and driving the reset block 71 to move to one side inside the reset groove 7 while squeezing the restoring spring 72. When the upper mold 2 and the lower mold 1 are merged, the connecting block 73 moves to a suitable position.
