Description

Technical Field

[0001] The utility model relates to the technical field of reducer housing casting, in particular to a turnover type core shooting machine for casting reducer housing. Background Technique

[0002] A reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, playing a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. During the production of the reducer housing, a core shooting machine is often used for casting. However, in the current core shooting machine for casting, the molded sand cannot be automatically turned over after molding, resulting in time-consuming and laborious removal of the molded sand after molding.

[0003] As disclosed in Chinese Patent Publication No. CN220862672U, a core shooting machine for casting is disclosed. When in use, the core shooting machine body sprays the molding sand into the molding sand forming assembly. After the molding sand is formed, the staff starts two hydraulic cylinders. Since the connecting plate is fixedly installed on the left side of the two hydraulic cylinders, when the two hydraulic cylinders work, the connecting plate drives the molding sand forming die to move, realizing the automatic separation of the molding sand forming die from the molding sand forming die, and realizing automatic mold opening. Then, the staff starts the servo motor. Since the turning drive shaft is rotatably installed on the two support mounts, and the front side of the turning drive shaft is fixedly connected to the servo motor, when the servo motor works, the turning drive shaft drives the connecting plate to rotate 90 degrees, facilitating the falling off of the molded sand after molding, improving the work efficiency. Since the positioning plug rod is slidably installed inside the positioning seat, and the positioning plug rod is inserted into the lower arc-shaped positioning groove, it plays a limiting role on the turning drive shaft, making the turning drive shaft more stable after rotation. Also, since the return spring is installed outside the positioning plug rod, and the return spring is located between the positioning seat and the limit retaining ring, the elastic limit of the positioning plug rod is realized.

[0004] However, for the core shooting machine for casting in the above application, it only turns over the mold. When taking the material, the model often adheres to the inner wall of the mold, which is not convenient for quickly taking out the model, and directly taking the material by hand often has certain safety hazards. Therefore, there are certain limitations.

[0005] Therefore, we urgently need to provide a turnover type core shooting machine for casting reducer housing. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a flip - type core - shooting machine for casting a reducer housing, so as to solve the problems presented in the above - mentioned background technology. For the core - shooting machine for casting, it only flips the mold. When taking out the material, the model often adheres to the inner wall of the mold, which is not convenient for quickly taking out the model. Moreover, directly taking the material by hand often has certain potential safety hazards.

[0007] To achieve the above - mentioned purpose, the present utility model provides the following technical solution: A flip - type core - shooting machine for casting a reducer housing, including a support table and a core - shooting machine. The core - shooting machine is installed above the support table through support columns. A casting device is arranged above the support table, and a feeding device is arranged below the core - shooting machine.

[0008] The casting device includes a mold - closing unit, a feeding unit, and a flipping unit. The mold - closing unit is installed below the core - shooting machine, the feeding unit is installed above the mold - closing unit, and the flipping unit is installed on both sides of the mold - closing unit.

[0009] The mold - closing unit includes side plates, guiding optical axes, a mold - closing seat, electric telescopic rods, and a fixed mold seat. The two side plates are respectively fixedly connected to the left and right sides below the core - shooting machine. The four guiding optical axes are respectively fixedly connected to the four corners between the two side plates. The mold - closing seat is slidably connected to the guiding optical axes. The two electric telescopic rods are respectively fixedly connected to the upper and lower ends of the right - hand surface of the left - hand side plate, and their right ends are connected to the mold - closing seat. The fixed mold seat is fixedly connected to the left - hand surface of the right - hand side plate. Start the electric telescopic rods to push the mold - closing seat to slide to the right along the guiding optical axes until it completes mold - closing with the fixed mold seat. At this time, start the core - shooting machine for casting processing. Moreover, the mold - closing seat moving to the right along the guiding optical axes can effectively avoid the situation where the mold - closing seat is skewed and cannot complete mold - closing.

[0010] Further improvement lies in that the feeding unit includes an electric push rod, a pushing plate, and a knocking component. The electric push rod is installed at the center of the left - hand outer surface of the mold - closing seat, and its output end extends into the interior of the mold - closing seat. The pushing plate is fixedly connected to the right end of the electric push rod and fits against the inner wall of the mold - closing seat. The knocking component is installed on the top of the mold - closing seat.

[0011] A further improvement lies in that the knocking component includes a rotary motor, a stable bearing seat, a rotating shaft, a spring, and a rubber ball. The rotary motor is installed on the top of the mold clamping base. The stable bearing seat is installed on the right side of the rotary motor. The rotating shaft is connected to the output end of the rotary motor and is rotatably connected to the inside of the stable bearing seat. The spring is fixedly connected to the outer end of the rotating shaft, and the rubber ball is fixedly connected to the outer end of the spring. After casting is completed, the rotary motor is started to drive the rotating shaft to rotate inside the stable bearing seat, thereby driving the spring at one end of the rotating shaft to rotate, and further driving the rubber ball to rotate and knock the mold, so that the model is separated from the inner wall of the mold during vibration. Then, the electric telescopic rod is started to pull the mold clamping base back to its original position. Subsequently, the electric push rod is started to push the pushing plate to push out the model inside the mold clamping base, and the material taking can be quickly completed.

[0012] A further improvement lies in that the flipping unit includes a flipping bearing seat, a flipping shaft, and a flipping motor. The two flipping bearing seats are respectively installed on the two support platforms. The two flipping shafts are respectively rotatably connected to the inside of the flipping bearing seats, and their inner ends are respectively connected to the two side plates. The flipping motor is installed on the left support platform, and its output end is connected to the left flipping shaft. During the feeding process, the flipping motor is started to drive the flipping shaft to rotate inside the flipping bearing seat, thereby driving the entire mold clamping unit to flip 180°, facilitating the feeding process.

[0013] A further improvement lies in that the feeding device includes a conveying table, a conveyor belt, and side baffles. The conveying table is installed below the core shooter. The conveyor belt is rotatably connected to the inside of the conveying table. The two side baffles are respectively installed on the left and right sides of the upper surface of the conveying table.

[0014] A further improvement lies in that the conveyor belt is made of rubber material, and elastic rubber pads are installed on the inner walls of the side baffles. The discharged models fall on the conveyor belt and are directly conveyed out through the conveyor belt, eliminating the need for manual material receiving, improving the safety of casting. Moreover, the setting of the elastic rubber pads on the side baffles better protects the models and prevents them from being damaged by impact.
