[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a U-shaped bracket forming mold with an ejection structure, according to... Figure 1 and Figure 2As shown, a mold body is located at the middle of the upper end of the processing table 1, and the mold body includes a lower mold 2 and an upper mold 3. A lifting base 202 is located at the bottom of the lower mold 2, and limit side plates 203 are symmetrically arranged on both sides of the upper end of the lifting base 202. The limit side plates 203 improve the accuracy of the sealing frame 302 moving down and fitting with the lifting base 202. At the same time, a positioning protrusion 204 is located on the rear side of the middle of the upper end of the lifting base 202. A placement seat 10 is located at the lower end of the processing table 1, and multiple electric telescopic rods 11 are located on the upper end of the placement seat 10. The output end of the electric telescopic rods 11 passes through the bottom of the processing table 1 and the lower mold 2 and connects to the lower end of the lifting base 202. The electric telescopic rods 11 push the lifting base 202 upward, which facilitates the upward movement and material removal of the formed U-shaped bracket. The upper ends of the upper mold 3 are connected to the support top frame 5 located on the rear side of the middle of the upper end of the processing table 1 by symmetrically arranged electric hydraulic cylinders 4. An injection pipe 9 is symmetrically arranged on the upper end of the upper mold 3. Meanwhile, the injection pipe 9 is connected to the quantitative feeder 6 through the three-way connector 8. The upper end of the quantitative feeder 6 is connected to the conveying pipe 7, and the quantitative feeder 6 is set on the upper end of the support top frame 5. Through the quantitative feeder 6, the molten metal can be quantitatively delivered to the mold body through the injection pipe 9, effectively avoiding the difference in the amount of molten metal delivered and improving the quality of the U-shaped bracket after molding. Multiple heat dissipation fins 301 are equidistantly installed on the top of the upper mold 3. The heat dissipation fins 301 dissipate the heat in the upper mold 3. The lower end of the upper mold 3 is provided with a sealing frame 302. The sealing frame 302 has a U-shaped structure. The outer side of the lower end of the sealing frame 302 is attached to the inner side of the corresponding limit side plate 203, and the middle of the rear side of the inner side of the sealing frame 302 is attached to the rear side of the positioning protrusion 204. Through the use of the sealing frame 302, the lifting base 202 and the positioning protrusion 204, the cavity between them becomes a molding cavity, so that the molten metal is cooled down to form a U-shaped bracket.

[0020] according to Figure 1 , Figure 3 and Figure 4As shown, a liquid channel 201 is provided in the middle of the lower mold 2 shell, and the liquid channel 201 has a ring structure. At the same time, the two ends of the liquid channel 201 are connected to the cooling component 12. The liquid channel 201 facilitates the flow of metal coolant and dissipates heat in the lower mold 2, improving the cooling efficiency of the U-shaped bracket after molding. The cooling component 12 is installed on one side of the upper end of the processing table 1. The cooling component 12 includes a liquid storage tank 1201, and the upper and lower ends of the liquid storage tank 1201 are respectively provided with a cooling chamber and a liquid storage chamber. At the same time, the upper and lower ends of the cooling chamber and the liquid storage chamber near the lower mold 2 are respectively provided with a discharge pipe 1204 and a delivery pipe 1202. The discharge pipe 1204 and the delivery pipe 1202 are respectively internally threaded to one end of the corresponding liquid channel 201. A quantitative delivery pump 1203 is provided on the delivery pipe 1202. The lower end of the liquid storage tank 1201 on the other side of the cooling chamber is connected to the lower end of the other side of the liquid storage chamber through a circulation pipe 1208. A solenoid check valve 1209 is installed on the 208. Through the circulation pipe 1208 and the solenoid check valve 1209, the metal coolant inside the cooling chamber is easily transported to the storage chamber for reuse. A heat dissipation top seat 1205 is installed at the upper end of the storage tank 1201, and an electric stirrer 1206 is installed in the middle of the heat dissipation top seat 1205. The lower end of the electric stirrer 1206 is located inside the cooling chamber. The electric stirrer 1206... 06. The metal coolant inside the cooling chamber is stirred so that the heat absorbed by it is discharged through the heat dissipation top seat 1205, which makes the metal coolant cool down quickly. A temperature detector 1207 is set on the upper front of the liquid storage tank 1201, located in front of the cooling chamber. A heat dissipation box 13 is set on the other side of the upper end of the processing table 1. At the same time, multiple air inlet mesh plates 1301 are installed at equal intervals on the front and back of the heat dissipation box 13. The temperature of the processing area is reduced and the cooling efficiency is improved through the heat dissipation box 13.

[0021] In use, the electric hydraulic cylinder 4 is activated to push the upper mold 3 downward, causing the sealing frame 302 at the lower end of the upper mold 3 to move downward synchronously until the bottom of the upper mold 3 is in contact with the upper end of the lower mold 2 and the upper end of the positioning protrusion 204. At the same time, the lower end of the sealing frame 302 is in contact with the upper end of the lifting base 202, and the outer side of the lower end of the sealing frame 302 is in contact with the inner side of the corresponding limiting side plate 203. After completion, the molten metal is conveyed to the quantitative feeder 6 through the conveying pipe 7. Then, the quantitative feeder 6 conveys a fixed amount of molten metal through the three-way connector 8 and the injection pipe 9 into the mold body. At the same time, the quantitative infusion pump 1203 and the cooling box 13 are activated, so that the molten metal in the storage chamber at the lower end of the storage tank 1201 enters the liquid channel 201 through the conveying pipe 1202 to absorb heat. Then, the fluidity of the molten metal is used to discharge the molten metal through the discharge pipe 1204. The hot metal coolant is delivered to the cooling chamber, where it is stirred by an electric stirrer 1206. This allows the heat to be discharged through the heat dissipation top seat 1205. Simultaneously, the temperature detector 1207 monitors the temperature. When the temperature drops to a usable level, the electromagnetic check valve 1209 is opened, allowing the metal coolant in the cooling chamber to enter the storage chamber for reuse through the circulation pipe 1208. Meanwhile, the cooling fan box 13 rotates to cool the temperature on the outside of the mold body. After the U-shaped bracket is shaped, the electric hydraulic cylinder 4 is activated to push and pull the upper mold 3 and the sealing frame 302 to move upwards and separate from the lower mold 2. Then, the electric telescopic rod 11 is activated to push the lifting base 202 upwards, causing the U-shaped bracket formed on the upper end of the lifting base 202 to move upwards simultaneously above the lower mold 2. The cooling fan box 13 then rotates to provide air cooling for the U-shaped bracket, reducing its temperature and improving safety during material handling.
