Description

Technical Field

[0001] The invention relates to the field of mold processing, in particular to a mold turning mechanism. Background Art

[0002] The processing and production of molds has developed rapidly in our country. As people's requirements for time and labor costs become increasingly stringent, people have begun to vigorously explore the maximum degree of mechanization and automation that can be achieved in the mold processing process.

[0003] During the processing and assembly of the box-shaped mold, the mold box falls onto the conveyor line for transmission, and then is transmitted to the next processing or assembly step. Some mold boxes need to be flipped after demoulding so that the opening is upward or downward, so that the molded mold box can be used as a receiving part or a cover part in the subsequent assembly. When the mold box is large in size, it is time-consuming and laborious to flip it manually. The inventor believes that there is a defect that manual flipping of the mold box requires a large labor cost. Summary of the invention

[0004] In order to reduce the manpower consumed in the mold processing process and improve the mechanization and automation of mold production, the present invention provides a mold turning mechanism.

[0005] The mold turning mechanism provided by the present invention adopts the following technical solution:

[0006] A mold turning mechanism, comprising:

[0007] The frame is arranged on the conveyor line;

[0008] A front fork frame is rotatably connected to the frame, the upper surface of the front fork frame can rotate by an angle of not less than 90°, a driving member for driving the front fork frame to rotate is provided on the frame, and the upper surface of the front fork frame is used to receive the mold box to be turned over;

[0009] The rear end fork frame is rotatably connected to the frame, and a linkage is provided between the front end fork frame and the rear end fork frame; in the process of the front end fork frame rotating to a vertical state, the rear end fork frame rotates toward the vertical state, and the upper surface of the front end fork frame and the upper surface of the rear end fork frame approach each other; the front end fork frame and the rear end fork frame can both rotate to a horizontal state, and one end of the front end fork frame and the rear end fork frame along the length direction approach each other.

[0010] Preferably, the driving member includes a sensor and a driving cylinder, the sensor is arranged on the front end fork frame and the rear end fork frame, and the sensor is electrically connected to the driving cylinder; when the sensor senses that the mold box is completely placed on the front end fork frame, the driving cylinder starts to extend; when the sensor senses that the mold box is completely placed on the rear end fork frame, the driving cylinder starts to retract.

[0011] Preferably, the front ends of the front fork frame and the rear fork frame can be rotated to abut against the upper surface of the conveyor line.

[0012] Preferably, the linkage member comprises a connecting rod, and both ends of the connecting rod are rotatably connected to the rotating end side walls of the front end fork frame and the rear end fork frame respectively.

[0013] Preferably, the connecting rod includes a first rod, a threaded sleeve and a second rod, the first rod and the second rod are reverse threaded rods, the first rod and the second rod are respectively threadedly connected to the two ends of the threaded sleeve, and the ends of the first rod and the second rod that are away from each other are respectively rotatably connected to the front fork frame and the rear fork frame.

[0014] Preferably, a connecting block is integrally connected to the upper surface of the rear end fork frame, and the connecting rod is rotatably connected to the connecting block along one side in the thickness direction.

After the mold box is placed on the front end fork frame, the front end fork frame can be rotated by the driving member. When the front end fork frame rotates, the rear end fork frame is driven to rotate through the linkage member, so that the front end fork frame and the rear end fork frame rotate at the same time and the upper surfaces of the two are gradually approached. When the rotation angle of the front end fork frame is not less than 90°, the mold box on the upper surface of the front end fork frame rotates freely and falls under the action of gravity, and then falls on the upper surface of the rear end fork frame close to the front end fork frame. Then the front end fork frame returns to its position and rotates, driving the rear end fork frame to return to a horizontal position. The rotation of the rear end fork frame drives the mold box to rotate, thereby completing the flipping of the mold box. The simple structure can complete the step of flipping the mold box, which is beneficial to improving the mechanization and automation of the mold production process, and then to improving efficiency, and to reducing the manpower and material resources consumed in the mold processing process.

Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0021] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0022] The following is combined with Figure 1 The present invention is described in further detail.

[0023] The embodiment of the invention discloses a mold turning mechanism.

[0024] A mold turning mechanism, comprising:

[0025] Frame 1, arranged on the conveyor line;

[0026] The front fork frame 2 is rotatably connected to the frame 1. The upper surface of the front fork frame 2 can rotate by an angle of not less than 90°. The frame 1 is provided with a driving member for driving the front fork frame 2 to rotate. The upper surface of the front fork frame 2 is used to receive the mold box to be turned over.

[0027] The rear end fork frame 3 is rotatably connected to the frame 1, and a linkage is provided between the front end fork frame 2 and the rear end fork frame 3; during the process of the front end fork frame 2 rotating to a vertical state, the rear end fork frame 3 rotates toward the vertical state, and the upper surface of the front end fork frame 2 and the upper surface of the rear end fork frame 3 approach each other; the front end fork frame 2 and the rear end fork frame 3 can both rotate to a horizontal state, and one end of the front end fork frame 2 and the rear end fork frame 3 along the length direction approach each other.

[0028] The frame 1 is set on the conveyor line of mold processing, so that the front end fork frame 2 and the rear end fork frame 3 are set on the conveyor line. After the mold box is placed on the front end fork frame 2, the front end fork frame 2 can be rotated by the driving member. When the front end fork frame 2 rotates, the rear end fork frame 3 is driven to rotate through the linkage member, so that the front end fork frame 2 and the rear end fork frame 3 rotate at the same time and the upper surfaces of the two gradually approach each other. When the rotation angle of the front end fork frame 2 is not less than 90°, the mold box on the upper surface of the front end fork frame 2 rotates freely and falls under the action of gravity, and then falls on the upper surface of the rear end fork frame 3 close to the front end fork frame 2. Then the front end fork frame 2 returns to its original position and rotates, driving the rear end fork frame 3 to rotate back to a horizontal position. The rotation of the rear end fork frame 3 drives the mold box to rotate, thereby completing the flipping of the mold box. The simple structure can complete the step of flipping the mold box, which is conducive to improving the mechanization and automation of the mold production process, and then to improving efficiency, and to reducing the manpower and material resources consumed in the mold processing process.

[0029] Reference Figure 1 In this embodiment, the driving member includes a sensor and a driving cylinder 4. The sensor is arranged on the front fork frame 2 and the rear fork frame 3, and the sensor is electrically connected to the driving cylinder 4. When the sensor senses that the mold box is completely placed on the front fork frame 2, the driving cylinder 4 starts to extend; when the sensor senses that the mold box is completely placed on the rear fork frame 3, the driving cylinder 4 starts to retract.

[0030] The sensor is arranged on the front fork frame 2. When the sensor senses that the mold box is completely placed on the front fork frame 2, that is, when the front fork frame 2 can be turned over, the sensor transmits a signal to the drive cylinder 4, thereby starting the drive cylinder 4, so that the drive cylinder 4 assists in rotating the front fork frame 2. When the sensor senses that the mold box is completely placed on the rear fork frame 3, that is, when the rear fork frame 3 can be turned over, the sensor transmits a signal to the drive cylinder 4, thereby starting the drive cylinder 4, so that the drive cylinder 4 assists in rotating the front fork frame 2 and drives the rear fork frame 3 to rotate.

[0031] In this embodiment, one end of the driving cylinder 4 is rotatably connected to the front fork frame 2, and the other end is rotatably connected to the inner side wall of one end of the frame 1 along the length direction.

[0032] In this embodiment, the sensor is provided with an infrared module, and the sensor is provided on the upper surface of one end of the front fork frame 2 close to the rear end plug-in. When the mold box blocks the infrared rays of the sensor, it indicates that the mold box has completely moved to the front fork frame 2. In other embodiments, the sensor may also be provided with a gravity sensing module.

[0033] Reference Figure 1 In this embodiment, the front ends of the front fork frame 2 and the rear fork frame 3 can be rotated to abut against the upper surface of the conveyor line.

[0034] When the upper surface of the front fork frame 2 abuts against the conveyor line, the mold box slides onto the front fork frame 2 due to the friction of the conveyor line, so that the operation of placing the mold box on the front fork frame 2 can be mechanized and automatically realized, making the flipping of the mold box easier.

[0035] Reference Figure 1 In this embodiment, the linkage member includes a connecting rod 5, and both ends of the connecting rod 5 are rotatably connected to the rotating end side walls of the front fork frame 2 and the rear fork frame 3 respectively.

[0036] The two ends of the connecting rod 5 are respectively connected to the ends of the front fork frame 2 and the rear fork frame 3. When the front fork frame 2 rotates, since the length of the connecting rod 5 is constant, the front fork frame 2 drives the rear fork frame 3 to rotate together through the connecting rod 5, thereby realizing the linkage between the front fork frame 2 and the rear fork frame 3.

[0037] In this embodiment, when the front fork frame 2 rotates to a vertical state, the end of the connecting rod 5 connected to the front fork frame 2 moves to directly below the rotating shaft of the front fork frame 2, and the connecting rod 5 is located on one side of the front fork frame 2 and the rear fork frame 3, so that the rotation of the connecting rod 5 will not be restricted by the movement of the front fork frame 2 or the rear fork frame 3, which is beneficial to ensure the smoothness of the movement of the front fork frame 2, the connecting rod 5 and the rear fork frame 3.

[0038] Reference Figure 1 In this embodiment, the connecting rod 5 includes a first rod, a threaded sleeve 6 and a second rod 7. The first rod and the second rod 7 are reverse threaded rods. The first rod and the second rod 7 are respectively threadedly connected to the two ends of the threaded sleeve 6, and the ends of the first rod and the second rod 7 that are away from each other are respectively rotatably connected to the front fork frame 2 and the rear fork frame 3.

[0039] By rotating the threaded sleeve 6, the first rod or the second rod 7 is moved closer or farther away, and the length of the connecting rod 5 can be adjusted, so that the proximity between the front fork frame 2 and the rear fork frame 3 can be adjusted, so that the rear fork frame 3 can receive mold boxes of different sizes.

[0040] Reference Figure 1 In this embodiment, a connecting block 8 is integrally connected to the upper surface of the rear end fork frame 3, and the connecting rod 5 is rotatably connected to the connecting block 8 along one side of the thickness direction.

[0041] The connecting rod 5 is connected to the connecting block 8, so that the connection point between the connecting rod 5 and the rear end fork frame 3 is closer to the front end fork frame 2, making the linkage of the connecting rod 5 more flexible. On the other hand, when the mold box falls onto the rear end fork frame 3, the mold box abuts against the connecting block 8. The connecting block 8 can serve as a limiting part of the mold box to reduce the abutment between the mold box and the connecting rod 5.

[0042] Reference Figure 1 In this embodiment, a height-adjustable foot 9 is provided at the bottom of the frame 1 .

[0043] By adjusting the height of the adjusting foot 9, the height of the front fork frame 2 and the rear fork frame 3 on the upper surface of the frame 1 can be adjusted, so that the front fork frame 2 and the rear fork frame 3 can adapt to different working conditions, which is beneficial to improving the adaptability of the mold turning mechanism.

[0044] In this embodiment, the ground adjusting foot 9 includes an upper part and a lower part connected to the frame 1. The upper part is a sleeve with an internal thread, and the lower part is threadedly connected to the upper part. When the height needs to be adjusted, the lower part can be adjusted by rotating the lower part; the upper part is a part of the square frame 1. When the lower part rotates, the upper part is restricted by the frame 1 and is difficult to rotate, making the ground adjusting foot 9 easier to adjust.

[0045] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
