Description

Technical Field

[0001] This utility model relates to the field of casting machine equipment technology, specifically a large gear servo tilting gravity casting machine. Background Technology

[0002] Gravity casting is a process in which molten metal is poured into a metal mold cavity under the influence of Earth's gravity to obtain castings. In a broad sense, gravity casting includes sand casting, metal mold casting, investment casting, lost foam casting, and clay casting; in a narrow sense, it specifically refers to metal mold casting. A gravity casting machine generally refers to a machine that performs the opening and closing of the mold and the removal of parts during gravity casting. Metal mold gravity casting machines are divided into two main categories: tilting gravity casting machines and fixed gravity casting machines. Tilting gravity casting machines can achieve tilting pouring, which can effectively improve the internal quality of the castings. Current tilting gravity casting machines prevent air bubbles from being generated during the pouring process by rotating the mold; however, most current machines can only rotate 90 degrees, making it impossible to precisely control the rotation angle.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0008] Preferably, the flipping mechanism includes a gear ring, a drive gear, and an RV reducer. The output shaft of the RV reducer is connected to the drive gear, and the drive gear meshes with the outer ring of the gear ring.

[0009] Preferably, the upper end of the toothed ring is fixedly connected to the long shaft of the side wall of the rotating frame, and the bottom end of the rotating frame is fixedly provided with a die-casting mold.

[0010] Preferably, the die-casting mold is provided with a gate connected to the inside of the mold, and a tie rod is provided above the die-casting mold, the tie rod being located on the side of the gate.

[0012] (III) Beneficial Effects

[0013] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: The large gear servo tilting gravity casting machine of this utility model drives the drive gear through the RV reducer and cooperates with the gear ring, which can accurately control the rotation of the gear ring and thus control the tilting angle value of the rotating frame. The entire tilting process runs smoothly. The RV reducer has an angle mechanical self-locking function, which can prevent unstable tilting during operation and thus prevent safety accidents.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-2 As shown: A large gear servo-driven gravity casting machine includes a frame 1 and a die-casting mold 8. A flipping mechanism is provided on the frame 1, and a servo motor 6 is fixed on one side of the frame 1. The output end of the servo motor 6 is connected to an RV reducer 5, which is connected to a drive gear 4. The die-casting mold 8 is fixed on a rotating frame 12, and a mold opening and closing mechanism 2 is provided above the die-casting mold 8. The servo motor 6 provides power output to the RV reducer 5, which drives the drive gear 4 to rotate, thereby driving the gear ring 3 to rotate. The rotation of the gear ring 3 can be precisely controlled, thereby accurately controlling the flipping angle of the rotating frame 12. This is no longer limited to flipping the die-casting mold 8 by only 90 degrees. As a result, during the slow rotation of the die-casting mold 8, air bubbles are prevented from forming in the molten metal, further ensuring the quality of the finished product.

[0019] The overturning mechanism includes a gear ring 3, a drive gear 4, and an RV reducer 5. The output shaft of the RV reducer 5 is connected to the drive gear 4. The drive gear 4 meshes with the outer ring of the gear ring 3. The RV reducer is used instead of a direct motor drive to drive the gear 4 to achieve the angle mechanical self-locking function, thereby preventing instability and overturning during operation that could lead to safety accidents.

[0020] The upper end of the gear ring 3 is fixedly connected to the long shaft of the side wall of the rotating frame 12, and the bottom end of the rotating frame 12 is fixedly provided with a die-casting mold 8.

[0021] The die-casting mold 8 is provided with a gate 9 connected to the inside of the mold. A tie rod 10 is also provided above the die-casting mold 8. The tie rod 10 is located on the side of the gate 9, and the molten metal is poured in from the gate 9.

[0022] The mold opening and closing mechanism 2 includes a water-cooling structure, which can block the transfer of heat and greatly reduce the probability of the main top cylinder malfunctioning. The die-casting mold 8 has a connecting pipe 7 connected to its rear wall.

[0023] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
