[0002] A wafer is a silicon wafer used to manufacture silicon semiconductor circuits. Its raw material is silicon. High-purity polycrystalline silicon is dissolved and mixed with silicon crystal seeds, and then slowly pulled out to form a cylindrical single-crystal silicon. After grinding, polishing and slicing, the silicon crystal rod is formed into a silicon wafer, which is a wafer. Domestic wafer production lines are mainly 8-inch and 12-inch. Wafer cleaning is an important process step in semiconductor manufacturing, which aims to remove various contaminants from the wafer surface to ensure that subsequent processes can be carried out on a clean surface. During wafer cleaning, cleaning brushes and foam are used to clean its surface. The foam is made by foaming plastic particles.

[0003] However, the hot pressing and foaming process currently generates a large amount of heat, resulting in a high surface temperature of the foam, which makes it inconvenient for workers to handle and can easily cause hand injuries. Furthermore, when the mold is separated, a large amount of hot air will fly outward and splash onto the workers' faces, causing discomfort. Therefore, this utility model provides a mold for manufacturing and processing wafer cleaning brush foam to meet people's needs. Utility Model Content

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1-4As shown, this utility model provides a technical solution: a molding die for manufacturing and processing wafer cleaning brush foam, including a base 1. Hydraulic telescopic rods 2 are fixedly installed at the four corners of the top of the base 1. A lifting plate 3 is fixedly connected between the top ends of the hydraulic telescopic rods 2. An upper mold base 4 is fixedly installed at the middle of the bottom end of the lifting plate 3. A lower mold base 5 is fixedly installed at the middle of the top of the base 1. A mold cavity 6 is opened at the middle of the top of the lower mold base 5. A front support 7 is fixedly installed at one end of the top of the lifting plate 3. A jet distribution box 8 is fixedly installed at the bottom of the front support 7. Jet holes 9 are equidistantly opened at one end of the jet distribution box 8. A cooling fan 10 is fixedly installed at the middle of the top of the front support 7. An air supply pipe 11 is fixedly connected to the air outlet at the bottom of the cooling fan 10. The jet distribution box 8 and the exhaust distribution box 13 are symmetrically distributed on both sides of the lifting plate 3. The bottom end of the air supply pipe 11 is fixedly connected to the middle of the jet distribution box 8. The middle end of the lifting plate 3 away from the front support 7... A rear support 12 is fixedly installed, and an air extraction and distribution box 13 is fixedly installed at the bottom of the rear support 12. One end of the air extraction and distribution box 13 has round holes equidistantly opened. Both the air jet hole 9 and the round holes are inclined towards the lower mold base 5. An axial flow fan 14 is fixedly installed in the middle of the surface of the air extraction and distribution box 13. Through the cooperation of the air jet distribution box 8 and the cooling fan 10, a certain airflow is generated and blown obliquely towards the surface of the foamed foam, which cools the foam and makes it safer for workers to handle. It prevents the large amount of heat attached to the surface of the molded foam from causing burns to the hands. At the same time, through the cooperation of the air extraction and distribution box 13 and the axial flow fan 14, the air near the lower mold base 5 is adsorbed. The large amount of heat generated during the foaming process when the upper mold base 4 and the lower mold base 5 are separated can be absorbed, preventing the heat from blowing out onto the workers' bodies and faces and causing discomfort. The blowing and cooling and the absorption of heat are carried out simultaneously, which improves the safety of demolding and material handling operations.

[0025] The bottom end of the mold cavity 6 is provided with an installation groove 15. Electric push rods 16 are symmetrically fixedly installed in the middle of the installation groove 15. A heat insulation plate 17 is fixedly connected between the top ends of the two electric push rods 16. A piston top plate 18 is fixedly connected to the top end of the heat insulation plate 17. A heat insulation frame 19 is fixedly installed on the inner wall of the installation groove 15. The heat insulation frame 19 surrounds the outside of the electric push rods 16. The piston top plate 18 is located at the bottom end inside the mold cavity 6. The edge of the piston top plate 18 fits against the inner wall of the mold cavity 6. Through the cooperation of the electric push rods 16 and the piston top plate 18, it is convenient to directly eject the foam after it has been foamed inside the mold cavity 6, which improves the efficiency of demolding and material removal, and prevents the foam from being embedded inside the mold cavity 6 and difficult to remove. At the same time, through the cooperation of the heat insulation plate 17 and the heat insulation frame 19, they surround the outside of the electric push rods 16, which plays a role in heat insulation protection and prevents the heat generated during hot pressing and foaming from damaging the electric push rods 16.

[0026] Threaded holes 20 are provided at the four corners of the bottom of the base 1, and adjusting screws 21 are installed at the four corners of the bottom of the base 1. The bottom of the adjusting screw 21 is fixedly connected to a support block 22, and the top of the adjusting screw 21 is inserted into the threaded hole 20. The adjusting screw 21 and the base 1 are connected by threads. Through the cooperation of the threaded hole 20 and the adjusting screw 21, the height of the base 1 and the lower mold base 5 can be adjusted, so that the height of the lower mold base 5 can be adapted to workers of different heights, thus making it more convenient for workers to operate.

[0027] The working principle and usage process of this utility model are as follows: First, the position of the equipment is adjusted. According to the height of the staff and the operation requirements, the equipment support is raised to the corresponding height. The support block 22 does not contact the ground. By rotating the adjusting screw 21, the support block 22 is made to fit tightly with the ground. The support block 22 and the adjusting screw 21 provide stable support for the base 1, so that the height of the lower mold base 5 meets the needs of the staff for loading and unloading materials. After the raw material is put into the mold cavity 6, the hydraulic telescopic rod 2 drives the lifting plate 3 and the upper mold base 4 to descend. The upper mold base 4 and the lower mold base 5 fit tightly together. The raw material inside the mold cavity 6 is hot-pressed and foamed. The hydraulic telescopic rod 2 will extend upward, pushing the upper mold base 4 away from the lower mold base 5.

[0028] During foaming and molding, a large amount of heat is generated. When the upper mold base 4 and the lower mold base 5 separate, the heat dissipates in all directions. The cooling fan 10 starts and generates airflow to blow on the top of the lower mold base 5, which cools the molded foam and blows away the dissipated hot airflow. At the same time, the axial flow fan 14 starts and generates airflow. The air extraction and distribution box 13 absorbs the airflow around the lower mold base 5 and removes the hot airflow, thereby rapidly cooling the surface of the foam. During demolding, no hot air will blow onto the face of the workers. Then, the electric push rod 16 extends upward and pushes the piston top plate 18 upward. The piston top plate 18 pushes the molded foam inside the mold cavity 6 upward, which the workers can then remove. The electric push rod 16 is protected by the heat insulation plate 17 and the heat insulation frame 19, so that the heat will not damage the electric push rod 16.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
