[0017] A process for automatically discharging a cylinder cover demolding, the specific method steps are as follows:

[0018] S1, opening the seal: starting the hydraulic cylinder on the sealing device to open the sealing cover upward;

[0019] S2, the mold counterclockwise rotation 120 degrees: start the motor to drive the first gear clockwise rotation, the first gear is forced to mesh in the second gear clockwise, the second gear is forced to drive the first fixed rod, the mold, the second fixed rod counterclockwise in the first rotating hole and the second rotating hole, so that the mold is stably counterclockwise rotation, until the rotation to 120 degrees, stop the motor, and then realize the mold feeding work state;

[0020] S3, mold limiting: in the first fixed rod counterclockwise rotation, it drives the rotating plate counterclockwise rotation, and the limiting slot 373 slides against one end of the limiting rod. The extension rod is forced to rotate clockwise while the limiting disc slides downward in the limiting hole. Through the transmission of the limiting disc, the third fixed rod on the limiting cylinder rotates clockwise in the fourth rotating hole. After the mold is counterclockwise rotated to 120 degrees, the lower end surface of the limiting disc is in contact with the inner bottom of the limiting hole, and then the mold is accurately rotated to 120 degrees.

[0021] S4, tensioning the steel wire rope: in the mold rotation to 120 degrees, through the rotation of the first transmission frame and the second transmission frame, the first circular arc rack and the second circular arc rack are meshed counterclockwise in the first vertical rack and the second vertical rack. The first T-shaped plate and the second T-shaped plate are forced to slide in the first T-shaped groove and the second T-shaped groove at the same time. Among them, the pull plate pulls one end of the plurality of steel wire ropes to one side, and the transmission power drives the feeding piece to rotate clockwise.

[0022] S5, the feeding piece clockwise rotation 30 degrees: after the mold is rotated to 90 degrees, the plurality of steel wire ropes are in a tight state, and the plurality of steel wire ropes are pulled downward by the tension of the pull plate. The feeding piece is rotated clockwise in the fourth fixed rod through the sixth rotating hole on the V-shaped frame, and the feeding piece is stretched upward on the spring body on one side. Until the mold is rotated to 120 degrees, the feeding piece also stops rotating. At this time, the feeding plate has been rotated to 30 degrees. Among them, the inner bottom surface of the feeding plate is opposite to the upper end of the mold, and the distance between the upper end of the feeding plate and the inner bottom surface of the feeding plate is greater than the thickness of the cylinder cover.

[0023] S6, receiving material: the upper end of the ejector device is started to lift the bottom of the cylinder cover in the mold, so that the cylinder cover is separated from the inside of the mold and falls on the upper end surface of the receiving part, and the cylinder cover slides downward along the inclination angle of the receiving part to one side surface of the stopper. At this time, the motor is started to drive the mold to return to the original direction, and the receiving part returns to the original state by the elastic force of the spring body. The cylinder cover is located outside the support body;

[0024] S7, cleaning: before cleaning the mold, the motor is started to drive the mold to rotate to 90 degrees, and the upper port of the mold is vertical. At this time, the workers can use auxiliary tools to clean the remaining mold.

[0025] (3) beneficial effects:

[0026] In the present application, the setting of the limiting assembly can effectively ensure that the mold is accurately counterclockwise rotated to 120 degrees, avoid the rotation angle of the mold exceeding 120 degrees, and also avoid affecting the automatic receiving work when the angle of the mold exceeds 120 degrees. During the rotation of the mold, the counterclockwise rotation of the mold can be ensured to be stable.

[0027] In the present application, the inner bottom surface of the receiving plate is opposite to the upper port of the mold, and the distance between the upper port of the receiving plate and the inner bottom surface of the receiving plate is greater than the thickness of the cylinder cover, so that the cylinder cover is completely separated from the inside of the mold after being separated.

[0028] In the present application, the 30-degree working state of the receiving part can automatically realize the receiving work, without the need for workers to participate in unloading, which can reduce the workload and speed up the work progress. After the receiving plate receives the material, the receiving part is in a U-shaped state, which can prevent the receiving part from falling to the ground due to deviation. The cylinder cover slides downward along the inclination angle of the receiving part to one side surface of the stopper, which can also prevent the cylinder cover from falling to the ground during downward movement, thereby preventing damage to the outer surface of the cylinder cover, ensuring the appearance and quality of the cylinder cover, increasing functionality, and improving practicality.

[0029] In the present application, the original state of the receiving part can make the workers easily and conveniently lift the cylinder cover after the receiving part receives the material and returns to the original position, and move it to the direction of other working procedures, which can avoid wasting a lot of time in lifting and improve the progress of cylinder cover casting.

[0030] In the present application, after the mold is rotated to 90 degrees, the upper port of the mold is vertical, which can facilitate the workers to clean and observe whether there is residual, improve the cleaning efficiency, and improve the cleanliness of the mold.
