[0002] Steamed buns are a staple food with a strong feeling of fullness. They are a traditional Chinese food made of flour and filling, which can be either meat or vegetarian. Well-made steamed buns have thin skins and plenty of filling, and are soft and delicious. Steamed bun molds are used to make steamed buns.

[0003] Existing steamed bun forming molds have difficulty quickly removing the buns from the mold during the forming process, resulting in low demolding efficiency and affecting the production efficiency of steamed buns. Furthermore, when sealing the steamed buns, excess bun skin accumulates at the sealing point, requiring manual removal of the excess skin. However, manually removing the excess skin can easily tear the formed steamed buns, leading to defects. To address these issues, we have proposed a steamed bun forming mold. Utility Model Content

[0004] The purpose of this utility model is to provide a steamed bun forming mold to solve the problems mentioned in the background art, such as the difficulty in quickly removing the steamed bun from the mold during the forming process, resulting in low demolding efficiency and affecting the production efficiency of steamed buns. Furthermore, when sealing the steamed bun, excess steamed bun skin accumulates at the sealing point, requiring manual removal of the excess skin. However, manually removing the excess skin can easily tear the formed steamed bun, leading to defects in the finished product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steamed bun forming mold, comprising a base and a forming platform. The forming platform is fixedly connected to the top center of the base. An installation groove is formed at the bottom center of the forming platform. A motor is fixedly connected to the left side wall of the inner cavity of the installation groove. A rotating shaft is fixedly connected to the end of the power output shaft of the motor. Cams are fixedly connected to the left and right sides of the outer side wall of the rotating shaft. A mold groove is formed at the top center of the forming platform. A recess is formed at the bottom of the inner cavity of the mold groove. A top plate is provided in the inner cavity of the recess. A connecting rod is fixedly connected to the bottom of the top plate. The end of the connecting rod passes through the recess and extends into the inner cavity of the installation groove. A bottom plate is fixedly connected to the end of the connecting rod.

[0006] As a further description of the above technical solution:

[0007] The base has fixed plates on the top left and right sides, and electric push rods are fixedly connected to the upper inner side of the fixed plates.

[0008] As a further description of the above technical solution:

[0009] The end of the electric actuator is fixedly connected to a sealing template, and the top of the sealing template has a circular groove.

[0010] As a further description of the above technical solution:

[0015] A mounting frame is fixedly connected to the inner wall of the push plate, and a blade is fixedly connected to the top of the inner cavity of the mounting frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This steamed bun forming mold uses a motor to drive a rotating shaft, which in turn drives a cam to rotate. As the cam rotates, its protruding part pushes the bottom plate upward, causing the bottom plate to move the connecting rod upward. The connecting rod then moves the top plate upward, causing the top plate to push the steamed bun out of the mold groove, thus completing the demolding process. This makes it easier to remove the steamed bun from the mold, thereby improving the production efficiency of steamed buns.

[0018] 2. This bun forming mold, by activating the electric push rod, causes the sealing templates on both sides to close towards the center, thereby squeezing and sealing the bun. During the sealing process, excess bun skin is squeezed into the circular groove. Then, by pushing the push plate, the push plate causes the blade to close towards the center, thereby cutting off the excess bun skin at the circular groove. This allows the mold to quickly remove excess bun skin without manual removal, thus preventing the bun from breaking. Attached Figure Description

[0027] This utility model provides a steamed bun forming mold that facilitates bun demolding, improves bun production efficiency, and quickly removes excess bun skin without manual tearing, thus preventing bun breakage. Please refer to [link / reference]. Figure 1-4 It includes a base 100 and a molding table 200;

[0028] Please refer to it again. Figure 1-4 A fixing plate 110 is fixedly connected to the top left and right sides of the base 100. An electric push rod 120 is fixedly connected to the upper inner wall of the fixing plate 110. A sealing template 130 is fixedly connected to the end of the electric push rod 120. A circular groove 131 is opened on the top of the sealing template 130. A sliding groove 140 is opened in the middle of the top of the sealing template 130. Springs 150 are fixedly connected to the left and right side walls of the inner cavity of the sliding groove 140. A slider 160 is fixedly connected to the end of the spring 150. A push plate 170 is fixedly connected to the top of the slider 160. An installation frame 180 is fixedly connected to the inner wall, and a blade 190 is fixedly connected to the top of the inner cavity of the installation frame 180. By activating the electric push rod 120, the electric push rod 120 drives the sealing templates 130 on the left and right sides to close in the middle, thereby causing the sealing templates 130 to squeeze and seal the bun. When the bun is sealed, the excess bun skin is squeezed to the round groove 131. Then, by pushing the push plate 170, the push plate 170 drives the blade 190 to close in the middle, thereby causing the blade 190 to cut off the excess bun skin at the round groove 131.

[0029] In summary, this allows the mold to quickly remove excess dough from the buns without having to tear it off by hand, thus preventing the buns from breaking.

[0030] Please see Figure 1-3A molding platform 200 is fixedly connected to the top center of the base 100. A mounting groove 210 is provided in the bottom center of the molding platform 200. A motor 220 is fixedly connected to the left side wall of the inner cavity of the mounting groove 210. A rotating shaft 230 is fixedly connected to the end of the power output shaft of the motor 220. Cams 240 are fixedly connected to the left and right sides of the outer side wall of the rotating shaft 230. A mold groove 250 is provided in the top center of the molding platform 200. A recess 260 is provided at the bottom of the inner cavity of the mold groove 250. A top plate 270 is provided in the inner cavity of the recess 260. A connecting rod 280 is fixedly connected to the bottom of the top plate 270. The end of the connecting rod 280 passes through the groove 260 and extends into the inner cavity of the mounting groove 210. The end of the connecting rod 280 is fixedly connected to the base plate 290. The motor 220 drives the rotating shaft 230 to rotate, which in turn drives the cam 240 to rotate. When the cam 240 rotates, the protruding part of the cam 240 pushes the base plate 290 upward, which in turn drives the connecting rod 280 to move upward. The connecting rod 280 then drives the top plate 270 to move upward, which pushes the bun out of the mold groove 250, thus completing the demolding of the bun and making it easier to remove the bun from the mold.

[0031] In summary, this makes it easier to unmold the buns and improves the production efficiency of the buns.

[0032] In practical use, those skilled in the art first place the bun dough into the mold groove 250 and add filling. Then, by activating the electric push rod 120, the electric push rod 120 drives the sealing templates 130 on both sides to close towards the center, thereby squeezing and sealing the bun. When the bun is sealed, excess bun dough is squeezed into the circular groove 131. At this time, by pushing the push plate 170, the push plate 170 drives the blade 190 to close towards the center, thereby causing the blade 190 to cut off the excess bun dough at the circular groove 131. After cutting off the excess bun dough, the push plate 170 is released. 70 causes the spring 150 to rebound, driving the slider 160 to move, which in turn causes the push plate 170 to return to its original position. Then, the electric push rod 120 retracts, causing the sealing template 130 to open. The motor 220 then drives the rotating shaft 230 to rotate, which in turn drives the cam 240 to rotate. When the cam 240 rotates, the protruding part of the cam 240 pushes the bottom plate 290 upward, causing the bottom plate 290 to drive the connecting rod 280 to move upward. Finally, the connecting rod 280 drives the top plate 270 to move upward, causing the top plate 270 to push the bun out of the mold groove 250, thus completing the demolding of the bun.
