DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Referring to Figures 1-5, a tin bar cooling mold includes a base 1, a servo motor 2 is arranged on one side of the base 1, a gear 3 is arranged on the output shaft of the servo motor 2, a column 4 is arranged on the base 1, a turntable 5 is rotatably installed on the outer wall of the column 4, a tooth groove 6 is provided on the outer wall of the turntable 5, the tooth groove 6 and the gear 3 are meshed with each other, a plurality of mold cavities 7 are provided on the turntable 5, and the mold cavities 7 are evenly distributed in a circular shape, a plurality of support plates 8 are rotatably installed on the bottom end of the turntable 5, each support plate 8 corresponds to each mold cavity 7, the bottom end of the support plate 8 is in contact with the top end of the base 1, and a discharge trough 9 is provided on the base 1 The discharge chute 9 penetrates the outer wall of the base 1, a top plate 10 is arranged on the column 4, a tin water tank 11 is arranged on the top plate 10, a discharge pipe 12 is connected to the bottom end of the tin water tank 11, the discharge pipe 12 penetrates the top plate 10 and extends downward, a driving power supply 13 is arranged on the top plate 10, a plurality of cooling fans 14 are arranged on the bottom end of the top plate 10, and the plurality of cooling fans 14 are electrically connected to the driving power supply 13, a sliding rod 15 is slidably installed in the top plate 10, a wedge-shaped ejector rod 16 is arranged on the bottom end of the sliding rod 15, the wedge-shaped ejector rod 16 is located in the mold cavity 7, and a spring 17 is arranged between the wedge-shaped ejector rod 16 and the top plate 10.

The molten tin water in the tin water tank 11 flows into the mold cavity 7 through the discharge pipe 12. After the mold cavity 7 is filled with tin water, the servo motor 2 is driven to rotate. At this time, the gear 3 is engaged with the tooth groove 6 to drive the turntable 5 to rotate clockwise, so that the mold cavity 7 filled with tin water rotates to under the cooling fan 14. The driving power supply 13 is turned on to rotate the cooling fan 14 to cool the tin water. At this time, the discharge pipe 12 pours the next mold cavity 7. The continuous rotation of the turntable 5 and the setting of several cooling fans 14 increase the cooling speed of the tin water. When the molten tin is cooled and formed, it gradually rotates to the discharge chute 9. Since the bottom of the support plate 8 loses the support of the base 1, the support plate 8 rotates downward to open the bottom of the mold cavity 7. At the same time, the mold cavity 7 is located at the wedge-shaped ejector rod 16. The elastic force of the spring 17 causes the wedge-shaped ejector rod 16 to move downward, thereby ejecting the cooled and formed tin bar from the mold cavity 7 from top to bottom into the discharge chute 9, thereby completing the demoulding of the tin bar. The assembly line operation of the cooling mold effectively improves the turnover rate of the mold cavity 7, thereby improving the production efficiency of the tin bar.

Specifically, in the present embodiment, the turntable 5 and a plurality of support plates 8 are connected by a plurality of hinges 18. The hinges 18 are located on the same side of the support plates 8 and are tangent to the rotation direction of the turntable 5. The hinges 18 ensure the connection between the turntable 5 and the support plates 8, and ensure that the support plates 8 can automatically rotate to open the bottom of the mold cavity 7 when the support of the base 1 is lost, and when the turntable 5 rotates clockwise, after the support plates 8 contact the side of the discharge chute 9, the support plates 8 rotate upward to seal the bottom of the mold cavity 7.

Specifically, in the present embodiment, the bottom end of the discharge chute 9 is inclined, and the top end of the discharge chute 9 on the side of the rotation direction of the turntable 5 is inclined. The bottom of the discharge chute 9 is conducive to the sliding of the tin bar after demolding, and the inclined surface of the side cushions the upward rotation of the support plate 8 to block the bottom of the mold cavity 7, thereby preventing the support plate 8 and the discharge chute 9 from getting stuck.

Specifically, in this embodiment, the outer diameter of the column 4 at the rotation connection of the turntable 5 is smaller than the outer diameter of the column 4 body, which ensures the smooth rotation of the turntable 5 while providing axial positioning for the turntable 5 and ensuring the meshing between the tooth groove 6 and the gear 3.

Specifically, in this embodiment, a solenoid valve 19 is provided on the discharge pipe 12 , and the solenoid valve 19 enables the pouring of molten tin to be freely controlled, thereby preventing the molten tin from flowing onto the turntable 5 during the rotation of the turntable 5 and causing waste.

Specifically, in the present embodiment, the slide bar 15 is rectangular, and a baffle 20 is provided on the top of the slide bar 15 , and the baffle 20 is located above the top plate 10 . The shape of the slide bar 15 effectively avoids its own rotation, thereby ensuring the stability of the angle of the wedge-shaped top rod 16 , and the baffle 20 provides a downward limit for the slide bar 15 to prevent the slide bar 15 from separating from the top plate 10 .

Specifically, in the present embodiment, one side of the bottom end of the wedge-shaped push rod 16 is in the form of an inclined surface, which is located on the side opposite to the rotation direction of the turntable 5. When the tin bar is ejected from the mold cavity 7 by the wedge-shaped push rod 16, the wedge-shaped push rod 16 is located in the mold cavity 7. At this time, the turntable 5 that continues to rotate clockwise drives the mold cavity 7 to rotate, so that the side of the mold cavity 7 contacts the inclined surface of the wedge-shaped push rod 16, which promotes the wedge-shaped push rod 16 to drive the slide rod 15 to rise, and helps the turntable 5 to drive the mold cavity 7 to rotate smoothly to prevent jamming.

The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme and utility model concept of the utility model, shall make equivalent replacements or changes, which shall be covered by the protection scope of the utility model.
