Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal casting, in particular to a centrifugal casting machine. Background Art

[0002] Centrifugal casting is a technology and method that injects liquid metal into a high-speed rotating mold, causing the molten metal to perform centrifugal motion to fill the mold and form a casting. Due to the centrifugal motion, the liquid metal can fill the mold well in the radial direction and form a free surface of the casting.

[0003] For example, a new type of casting centrifuge with publication number CN219683902U pours molten steel into the casting centrifuge through a through hole. The motor drives the casting centrifuge to rotate, thereby completing the casting. After the casting is completed, the removal cover is rotated to move to the top of the casting centrifuge, and then the cylinder is started to push the top plate forward, thereby ejecting the casting from the casting centrifuge. The device is simple, practical, and effectively improves work efficiency. However, the cylinder pushes the top plate to move for demoulding in an eccentric position, and the top plate is unevenly stressed. Under the reaction force of the product, the connection between the top plate and the cylinder piston rod is likely to be damaged, resulting in the top plate being unable to push the product out. To this end, a centrifugal casting machine is proposed for improvement. Utility Model Content

[0007] The lower part of the casting cylinder is provided with a pillar, the top of the pillar is fixedly connected to a bearing frame, the bearing frame is sleeved on the outside of the rotating ring, a push plate is provided in the casting cylinder, the bottom surface of the push plate is fixedly connected to a push rod, there are several push rods and they are evenly arranged on the bottom surface of the push plate, the bottom end of the push rod is fixedly connected to a driving ring, the inner side of the pillar is fixedly connected to a support plate, a cylinder is provided on the support plate, the top end of the piston rod of the cylinder is fixedly connected to the driving frame, a motor is provided on the support plate, and the output shaft of the motor is fixedly connected to the casting cylinder.

[0008] Preferably, any of the above solutions is that the corners of the handle are rounded, and the size of the sealing gasket matches the internal cross-sectional size of the casting tube.

[0009] Preferably, from any of the above schemes, the rotating ring is fixedly connected to the middle of the casting cylinder, and there are a plurality of balls which are evenly arranged along the rotating ring.

[0010] The above technical solution uses a casting cylinder to provide space for centrifugal casting, while a cover seals the cylinder and facilitates centrifugal casting. A sealing gasket is placed on the bottom of the cover to enhance the sealing of the cylinder. Handles are provided around the cover to facilitate opening the cylinder. Rounded corners on the handles enhance comfort when opening the cover. A rotating ring, in conjunction with a bearing frame, supports the cylinder, limiting its horizontal and vertical displacement and enabling its rotation.

[0012] Preferably, any of the above solutions has a size of the push plate that matches an internal cross-sectional size of the casting tube, and the push rod is arranged to pass through the casting tube downward.

[0013] This technical solution employs a ball bearing on the outside of the rotating ring to reduce friction between the rotating ring and the supporting frame, thereby reducing noise during operation and ensuring smoother rotation of the casting drum. Support pillars support the supporting frame, which in turn supports the casting drum. A push plate is installed within the casting drum to push the formed product out of the drum. A push rod extends downward outside the drum and is equipped with a drive ring at its bottom, facilitating the cylinder's ability to pull or push the push plate for vertical displacement.

When the motor rotates the casting barrel, it rotates under the action of the push plate and push rods. After centrifugal casting is completed, the control cylinder pushes the drive frame upward, which in turn drives the drive ring upward. The drive ring, via the push rods, drives the push plate upward, which then pushes the product out of the casting barrel. Multiple push rods are evenly distributed on the bottom surface of the push plate, ensuring uniform force distribution across the push plate and more stable product ejection from the casting barrel.

Multiple push rods are evenly arranged on the bottom surface of the push plate, ensuring uniform force on all parts of the push plate. Multiple cylinders apply force to various parts of the drive frame, ensuring more balanced movement of the drive frame, which in turn makes the push plate more balanced and can more stably push the product out of the casting tube.

[0019] 2. This centrifugal casting machine utilizes a rotating ring, balls, pillars, and a supporting frame. The pillars support the supporting frame, which in turn supports the casting drum.
