The water in the water tank is pumped out by the water pump, and the water enters the cooling pipe through the water pipe, thereby absorbing the heat on the lower mold base, so that the molten metal is quickly cooled and formed. The water after absorbing the heat will flow into the spiral pipe through the water outlet pipe, so that the temperature at the injection pipe is increased, thereby avoiding the molten metal from being cooled in advance, and the heat preservation cover can prevent heat dissipation, thereby improving the energy utilization and environmental protection. Finally, the water will flow back to the water tank through the reflux pipe. In this process, the heat dissipation copper pipe will absorb the heat of the water and cool the water in the reflux pipe.

The environmentally friendly casting mold is provided with a main protective shell, a secondary protective shell, a heat dissipation port, a plug-in board, a slot, a spring, a card block and a card slot. The plug-in board is inserted into the slot. During the insertion process, the slot wall will push the card block to move, so that the card block moves to the inside of the plug-in board to compress the spring. After the plug-in board is fully inserted into the slot, the spring rebounds and pushes the card block to be inserted into the slot, and the secondary protective shell is fixed on the main protective shell, so as to protect the cooling pipe and prevent the cooling pipe from being damaged by bumps. The heat absorbed in the cooling pipe will be dissipated to the outside through the heat dissipation port, so as to prevent heat from accumulating between the main protective shell and the lower mold base.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: an environmentally friendly casting mold, including a lower mold base 1, a water tank 2 is installed below the lower mold base 1, a main protective shell 3 is installed above the lower mold base 1, plug plates 19 are connected on both sides of the main protective shell 3, springs 20 are connected inside the two sides of the plug plates 19, and a card block 21 is connected to one end of the spring 20. By plugging the plug plate 19 into the slot 22, the staff can quickly position and install the secondary protective shell 8, the operation is simple, and the installation efficiency is improved.

[0023] The side of the block 21 away from the spring 20 is hemispherical in design. The block 21 slides in the plug plate 19 and engages with the slot 23. The hemispherical block 21 enables the outer wall of the main protective shell 3 to push the block 21 to move conveniently and flexibly, thereby facilitating the staff to install and fix the secondary protective shell 8 to protect the cooling pipe 4 and prevent the cooling pipe 4 from being hit.

[0024] A cooling pipe 4 is arranged between the lower mold base 1 and the main protective shell 3, an upper mold base 5 is installed above the lower mold base 1, a heat preservation cover 6 is installed above the upper mold base 5, an injection molding tube 7 is connected to the upper mold base 5, a secondary protective shell 8 is installed on the main protective shell 3, and heat dissipation ports 9 are provided on the main protective shell 3 and the secondary protective shell 8, slots 22 are provided on both sides of the secondary protective shell 8, and card slots 23 are provided on both sides of the slot 22. The plug-in plate 19 is plugged into the slot 22, and an arc groove is provided on the side of the plug-in plate 19 opposite to the slot 22 to form a circular channel. The two ends of the cooling pipe 4 will pass through the circular channel formed by the plug-in plate 19 and the slot 22 to be connected with the water supply pipe 13 and the water outlet pipe 14, so that the cooling pipe 4 is pressed and fixed by the plug-in plate 19 to prevent the cooling pipe 4 from shaking when the water flows.

[0025] A water inlet pipe 10 is connected to one side of the water tank 2, and a water pump 11 is installed on the other side of the water tank 2. A water extraction pipe 12 is connected to one side of the water pump 11, and a water supply pipe 13 is connected above the water pump 11. A water outlet pipe 14 is connected to one side of the cooling pipe 4, and a spiral tube 15 is connected to one end of the water outlet pipe 14, and a return pipe 16 is connected to one end of the spiral tube 15. The water supply pipe 13, the water outlet pipe 14 and the return pipe 16 are all water supply hoses. The side of the cooling pipe 4 away from the water outlet pipe 14 is connected to the water supply pipe 13, and one end of the water extraction pipe 12 and the return pipe 16 are both connected to the water tank 2. The water flowing in the cooling pipe 4 absorbs the heat in the lower mold base 1, thereby rapidly reducing the temperature of the molten metal and improving the casting production efficiency of the parts.

[0026] A heat dissipation copper tube 17 is sleeved on the return pipe 16, the spiral tube 15 is spirally wound on the injection molding tube 7, and the spiral tube 15 is specifically arranged between the injection molding tube 7 and the insulation cover 6. A plurality of through holes 18 are opened on the heat dissipation copper tube 17. Compared with air, the heat dissipation copper tube 17 can quickly absorb the heat of the water in the return pipe 16, and the through holes 18 on the heat dissipation copper tube 17 can increase the contact area with the air, thereby increasing the heat dissipation speed and reducing the temperature of the water in the return pipe 16.

[0027] The working principle of the utility model is:

[0028] After the cooling tube 4 is placed between the main protective shell 3 and the lower die base 1, the insert plate 19 is inserted into the slot 22. As the insert plate 19 is inserted, the slot 22 wall pushes the card block 21 into the insert plate 19, so that the card block 21 compresses the spring 20. After the insert plate 19 is fully inserted into the slot 22, the spring 20 rebounds and pushes the card block 21 into the card slot 23. The secondary protective shell 8 is fixed on the main protective shell 3, and the two ends of the cooling tube 4 are pressed and fixed. Then, the water supply pipe 13 and the water outlet pipe 14 are connected to the cooling tube 4 together, and the water pump 11 is started. Water is pumped out from the water tank 2 through the pumping pipe 12, and the water enters the cooling pipe 4 through the water delivery pipe 13 to absorb the heat in the lower mold base 1, so that the molten metal is quickly cooled and formed. The water after absorbing the heat will flow into the spiral tube 15 through the outlet pipe 14, so that the temperature at the injection tube 7 is increased, thereby avoiding the molten metal from being cooled down prematurely, and the thermal insulation cover 6 can prevent heat dissipation. Finally, the water will flow back to the water tank 2 through the return pipe 16, and the heat dissipation copper tube 17 will absorb the heat of the water in the return pipe 16 to cool the water in the return pipe 16.
