Description

Technical Field

[0001] This application relates to the field of casting technology, and more particularly to a casting apparatus for differential pressure processing. Background Technology

[0002] Differential pressure casting is used to manufacture metal castings. This device uses the principle of differential pressure to apply a certain pressure in the casting mold to promote the molten metal to enter the mold and form the desired casting shape. It is suitable for manufacturing castings with large batches, complex shapes or high precision requirements, and has wide applications in automobile manufacturing, aerospace, machinery manufacturing and other fields.

[0003] Differential pressure casting equipment is a common casting process. Differential pressure casting machines are advanced and efficient casting equipment, mainly used to produce high-quality aluminum alloy, magnesium alloy and other castings. Currently, after casting, the workpiece is picked up with a pallet. However, when removing the workpiece from the equipment, the lack of a protective mechanism makes it easy for the workpiece to fall off the pallet, which can damage the formed workpiece and result in poor safety. Utility Model Content

[0004] The purpose of this invention is to provide a casting and forming device for differential pressure processing to solve the problems mentioned in the background art.

Each guide slide has a sliding seat slidably connected to its outer surface. The outer surfaces of the two sliding seats are fixedly connected to a receiving hopper. The outer surface of the receiving hopper is fixedly connected to two fixed boxes. Each fixed box has a telescopic cylinder fixedly connected inside. The output end of each telescopic cylinder extends to the top of the fixed box. The output ends of the two telescopic cylinders are fixedly connected to an annular connecting frame. The bottom surface of the annular connecting frame is fixedly connected to a protective side plate. The output end of the electric push rod is fixedly connected to the outer surface of one of the fixed boxes.

[0008] Preferably, the upper surface of the processing base is fixedly connected with a plurality of circular columns, and the top of each circular column is fixedly connected to the bottom surface of the lower mold base.

[0009] Preferably, the bottom surface of the supporting square plate is fixedly connected to two supporting round rods, and the outer surfaces of the two supporting round rods are jointly fixedly connected to a reinforcing inclined plate, the bottom end of which is fixedly connected to the outer surface of the processing seat.

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0013] Firstly, by using the hydraulic cylinder, upper mold base, lower mold base, crucible storage cylinder, gas injection pipe, and liquid addition pipe in combination, the upper mold base and lower mold base can be closed to form a certain pressure inside. The liquid riser pipe in the crucible storage cylinder can then be used to allow molten metal to enter and form the casting workpiece. This produces dense and uniform castings, improving product quality and performance, and increasing production efficiency.

[0014] Secondly, the use of electric push rods, guide slides, sliding seats, and receiving hoppers allows the electric push rods to move the receiving hoppers below the upper mold base, facilitating the receiving of cast workpieces. Furthermore, the use of fixed boxes, telescopic cylinders, annular connecting frames, and protective side plates allows the telescopic cylinders to move the annular connecting frames and protective side plates, causing them to rise and protect the sides of the receiving hopper. This prevents workpieces from falling out of the receiving hopper, ensuring the safety of the cast workpieces and achieving greater safety when receiving them, thus improving production efficiency and product quality.

A riser pipe 8 is provided inside the crucible storage cylinder 4. The top end of the riser pipe 8 is fixedly connected to the lower mold base 3. A support square plate 11 is fixedly connected to the outer surface of the square frame 5. A fixing plate 14 is fixedly connected to the back of the support square plate 11. An electric push rod 15 is fixedly connected to the upper surface of the fixing plate 14. Two guide slides 16 are fixedly connected to the upper surface of the support square plate 11. A sliding seat 17 is slidably connected to the outer surface of each guide slide 16. A receiving hopper 18 is fixedly connected to the outer surface of the two sliding seats 17. Two fixed boxes 19 are fixedly connected to the outer surface of the receiving hopper 18. Each fixed box 19 is internally connected to a telescopic cylinder 20. The output end of each telescopic cylinder 20 extends to the top of the fixed box 19. The output ends of two telescopic cylinders 20 are jointly connected to an annular connecting frame 21. A protective side plate 22 is fixedly connected to the bottom surface of the annular connecting frame 21. The output end of the electric push rod 15 is fixedly connected to the outer surface of one of the fixed boxes 19. Specifically, the electric push rod 15 can be used to push the receiving hopper 18 to move below the upper mold base 7, so that the receiving hopper 18 can be used to receive the cast workpiece. Through the use of the fixed box 19, telescopic cylinder 20, annular connecting frame 21 and protective side plate 22, the telescopic cylinder 20 can be used to push the annular connecting frame 21 and protective side plate 22 to move, so that the annular connecting frame 21 and protective side plate 22 rise up to protect the side of the receiving hopper 18, thereby preventing the workpiece in the receiving hopper 18 from falling and ensuring the safety of the cast workpiece.

[0026] In this embodiment, the outer surface of the crucible storage cylinder 4 is fixedly connected to a gas injection pipe 9 and a liquid addition pipe 10; the upper surface of the processing base 1 is fixedly connected to multiple cylindrical columns 2, and the top of each cylindrical column 2 is fixedly connected to the bottom surface of the lower mold base 3; specifically, the crucible storage cylinder 4 has strong applicability and can ensure the purity of the smelted material, while the liquid addition pipe 10 facilitates the addition of molten metal liquid into the crucible storage cylinder 4, improving the convenience of operation, and the cylindrical columns 2 can support the lower mold base 3, making the lower mold base 3 more stable during use, avoiding tilting and jamming, and improving practicality;

[0027] In this embodiment, two supporting round rods 12 are fixedly connected to the bottom surface of the supporting square plate 11. A reinforcing inclined plate 13 is fixedly connected to the outer surface of the two supporting round rods 12. The bottom end of the reinforcing inclined plate 13 is fixedly connected to the outer surface of the processing seat 1. A protective pad is provided inside the receiving square hopper 18.

The protective pad inside the receiving square hopper 18 can buffer the workpiece being picked up, and the protective frame 23 can make the upper mold seat 7 and the lower mold seat 3 more accurate when closing the mold, which is convenient for casting workpieces.

[0028] Working principle: When using this differential pressure casting device, the user first connects the power supply and connects the pressure tank via the air injection pipe 9. This generates pressure in the crucible storage cylinder 4. Molten metal is then added to the crucible storage cylinder 4 via the liquid addition pipe 10. The hydraulic cylinder 6 is then activated to push the upper mold base 7 and the lower mold base 3 to close. Under the differential pressure, the molten metal in the crucible storage cylinder 4 enters the upper mold base 7 and the lower mold base 3 through the liquid riser pipe 8. After casting, the hydraulic cylinder 6 is activated to lift the upper mold base 7. The electric push rod 15 is activated to push the fixed box 19, the receiving hopper 18 and the sliding seat 17 to slide on the guide slide 16, moving the receiving hopper 18 to the bottom of the upper mold base 7. The receiving hopper 18 is used to receive the workpiece formed in the upper mold base 7. Then, the two telescopic cylinders 20 can be activated to push the annular connecting frame 21 and the protective side plate 22 to move upward. The annular connecting frame 21 and the protective side plate 22 are used to protect and shield the side of the receiving hopper 18, so that it will not fall when receiving the casting workpiece, and the safety is higher.
