DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the utility model will be described in further detail below with reference to the drawings.

[0029] It should be noted that the terms "first", "second", and the like (if any) in the specification of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application 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 application. Instead, they are only examples of the utility model consistent with some aspects of the present application.

[0030] The eccentric spinning die needs to be turned over when cleaning or installing, but its special structure, combined with Figure 1 the three-dimensional view of the spinning die is shown, wherein Figure 1 ① in the sectional view of the spinning die,Figure 1 ② is a three-dimensional structure diagram of the spinning die, the spinning die is a trapezoidal rolling body rotating body shape, and the weight is heavy and more easy to adapt to rolling, that is, axial rotation O-O rotation as Figure 2 . Figure 2 ①, ②, ③ and ④ in the figure are different overturning states of the spinning die. The trapezoidal rotating body shape volume center point and the gravity center point are not in the same position. And the spinning die only contains the first lifting screw buckle 201 and the second lifting screw buckle 202 and the installation screw buckle 203 below the two side surfaces, which makes it extremely difficult to artificially overturn with the axis (A-A axis) corresponding to the die shape volume center 204 as the rotation axis. This overturning method is labor-intensive, time-consuming and labor-consuming, and low in efficiency, which becomes a bottleneck for safety production and improvement of production efficiency.

[0031] The utility model provides a kind of mould overturning device, to improve the efficiency of mould overturning, reduce the difficulty of mould overturning. Refer to Figure 3 , Figure 3 it is a schematic view of the mould overturning device provided by the utility model. The mould overturning device includes support structure, drive structure and rotating arm 14;Support structure is used to support drive structure and rotating arm 14;Drive structure is used to drive rotating arm 14 to run;Rotating arm 14 is used to make the gravity center 205 of mould 6 be located on the straight line passing through the center of first rotating shaft 5 of drive structure and perpendicular to the rotating face of first rotating shaft 5, and first rotating shaft 5 is the rotating shaft for driving rotating arm 14 to rotate.

[0032] Among them, support structure is the basis of the whole device, responsible for supporting drive structure and rotating arm 14. Support structure needs to be solid enough to ensure that it can remain stable during mould overturning. The design of support structure needs to consider stability and bearing capacity, which can be made of steel or other high-strength materials.

[0033] Drive structure is the power source of mould overturning device, responsible for driving rotating arm 14 to drive mould 6 to rotate. Drive structure may include motor, reducer, transmission shaft and other components, which work together to transmit power to rotating arm 14 and realize the overturning of mould 6. In addition, drive structure can also be equipped with control system to accurately control the overturning process.

[0034] The rotating arm 14 is a bridge connecting the mold 6 and the driving structure, responsible for transmitting the power provided by the driving structure to the mold 6, so that the mold 6 can be flipped. The design of the rotating arm 14 needs to meet at least two conditions, one is that the center line of the rotating shaft (i.e. the first rotating shaft 5) linked by the rotating arm 14 needs to be on the same straight line as the center of gravity 205 of the mold 6, where the straight line is perpendicular to the rotating surface of the first rotating shaft 5. In this way, the mold 6 can maintain balance during the flipping process and avoid tilting or instability. The second is that the length and strength of the rotating arm 14 need to be sufficient to withstand the weight of the mold 6 and the moment generated during the flipping process.

[0035] During the mold flipping process, the driving structure is started, and the power is transmitted to the rotating arm 14 through transmission shaft and other components. The rotating arm 14 starts to rotate under the action of the driving structure, driving the mold 6 to flip together. Because of the design of the rotating arm 14, the center of gravity 205 of the mold 6 is located on the straight line passing through the center of the first rotating shaft 5 and perpendicular to the rotating surface of the first rotating shaft 5, so the mold 6 can maintain balance and stability during the flipping process.

[0036] In one possible implementation, the first end of the rotating arm 14 is connected to the first rotating shaft 5, and the second end of the rotating arm 14 is connected to the mounting screw 203 of the mold 6; the distance between the first end and the second end is positively correlated with the distance between the mounting screw 203 of the mold 6 and the center of gravity 205 of the mold 6 in the vertical direction.

[0037] The first end of the rotating arm 14 is connected to the first rotating shaft 5, which is used to provide rotational motion so that the rotating arm 14 (and the mold 6 connected thereto) can rotate around the shaft. The second end of the rotating arm 14 is connected to the mounting screw 203 of the mold 6. The mounting screw 203 is a device for connecting and fixing the mold 6, ensuring that the mold 6 can be stably mounted on the rotating arm 14.

[0038] The distance between the first end and the second end of the rotating arm 14 (i.e. the length of the rotating arm 14) is positively correlated with the distance between the mounting screw 203 of the mold 6 and the center of gravity 205 of the mold 6 in the vertical direction. That is, when the position of the center of gravity 205 of the mold 6 in the vertical direction changes (for example, the distance between the mounting screw of different molds and the center of gravity of the mold in the vertical direction may be different), the length of the rotating arm 14 will also increase or decrease accordingly to maintain balance. In this way, the rotating arm 14 can be freely replaced according to different needs, thereby improving the flexibility of the system, optimizing the rotation and operation efficiency of the mold 6, and reducing potential mechanical failures and safety risks.

[0039] Reference Figure 4Another embodiment of the mold flipping device is shown. In one possible implementation, the first end includes a first anti-rotation table 24 for securing the connection between the rotating arm 14 and the first rotating shaft 5; the second end includes a second anti-rotation table 25 for securing the connection between the rotating arm 14 and the mold 6.

[0040] In combination Figure 5 A schematic diagram of the rotating arm 14 structure is shown. The first end is not just a simple connection point, but can also include a specific structure, namely the first anti-rotation table 24. The first anti-rotation table 24 is a structure designed to ensure stability and prevent relative rotation between the rotating arm 14 and the first rotating shaft 5. The main function of the anti-rotation table is to prevent unnecessary relative movement between the rotating arm 14 and the rotating shaft during rotation, thereby improving the stability of the system. Through the first anti-rotation table 24, the connection position between the rotating arm 14 and the first rotating shaft 5 is firmly fixed, ensuring smooth and accurate rotation.

[0041] Similarly, the second end is not just a simple connection point, but can also include a specific structure, namely the second anti-rotation table 25. The second anti-rotation table 25 is a structure designed to ensure stability and prevent relative rotation between the rotating arm 14 and the mold 6. Similar to the first anti-rotation table 24, the main function of the second anti-rotation table 25 is to prevent unnecessary relative movement between the rotating arm 14 and the mold 6 during rotation. Through the second anti-rotation table 25, the connection position between the rotating arm 14 and the mold 6 is firmly fixed, thereby ensuring the stability and accuracy of the mold 6 during rotation. Optionally, the mold 16 can include a mold anti-rotation table 207, which engages with the second anti-rotation table 25.

[0042] Referring to Figure 6 Another schematic diagram of the rotating arm 14 structure is shown, wherein, Figure 6 ① in FIG. is a left view of the rotating arm 14, Figure 6 ② in FIG. is a front view of the rotating arm 14. In one possible implementation, the second end includes first pin shaft holes, which correspond one-to-one with second pin shaft holes 206 on the mold 6, and any first pin shaft hole and the second pin shaft hole 206 corresponding to it are connected based on the pin shaft 26 to match the second end with the mounting screw 203.

[0043] The second end of the rotating arm 14 is specially designed to include first pin shaft holes. The pin shaft hole is a key part of the connection between the rotating arm 14 and the mold 6. The first pin shaft hole is located at the second end of the rotating arm 14 and is designed to receive the pin shaft 26. Each first pin shaft hole corresponds to a specific location on the mold 6. The second pin shaft hole 206 is located on the mold 6 and corresponds one-to-one with the first pin shaft hole on the rotating arm 14. The position and size of the second pin shaft hole 206 are precisely designed to ensure perfect matching with the first pin shaft hole.

[0044] The pin shaft 26 can be a cylindrical or rod-shaped connector used to secure two or more components together. In the present utility model, the pin shaft 26 is inserted into the corresponding first pin shaft hole and second pin shaft hole 206, thereby achieving a stable connection between the rotating arm 14 and the mold 6. This allows the rotating arm 14 to maintain a close connection with the mold 6 during rotation, while allowing a certain degree of flexibility to accommodate minor deformations or displacements that the mold 6 may encounter during rotation. The installation screw 203 refers to another structure or component on the mold 6 used to connect with the rotating arm 14, which is used in conjunction with the pin shaft 26, allowing the second end of the rotating arm 14 to be accurately connected with the corresponding position on the mold 6, ensuring smooth and precise rotational movement.

[0045] In one possible implementation, the first end is connected to the first rotating shaft 5 through an internal hexagonal bolt 7. The first end of the rotating arm 14 uses an internal hexagonal bolt 7 as a connecting element. The internal hexagonal bolt 7 is a commonly used fastener, with a head designed in the shape of an internal hexagon, requiring the use of a special internal hexagonal wrench or tool to tighten or loosen it. The first end of the rotating arm 14 is usually designed with a threaded hole or through hole that matches the internal hexagonal bolt 7, so that the screw can be passed through and tightened onto the first rotating shaft 5. The first rotating shaft 5 is also designed with corresponding threads or matching structures to tightly connect with the internal hexagonal bolt 7.

[0046] During the connection process, the internal hexagonal bolt 7 is first passed through the hole in the first end of the rotating arm 14 and is screwed into the threaded portion or matching structure of the first rotating shaft 5. Then, a special internal hexagonal wrench or tool is used to tighten the screw until the desired tightening force is achieved. The design of the head of the internal hexagonal bolt 7 makes the connection more compact, reducing space occupation. Secondly, since the screw needs to be tightened or loosened using a special tool, the safety and reliability of the connection are improved to some extent, preventing unauthorized disassembly or loosening. Finally, the tightening force of the internal hexagonal bolt 7 can be controlled by a special torque wrench, ensuring the stability and durability of the connection. Alternatively, different connection methods can be used in different use scenarios. In addition, different connection methods such as external hexagonal bolts 8 can be used between the second segment and the installation screw 203.

[0047] In one possible implementation, the number of rotating arms 14 is two, and the positions of the two rotating arms 14 are symmetrical relative to the mold 6. The mold 6 is supported and rotated by the two rotating arms 14 together. The positions of the two rotating arms 14 are symmetrical relative to the mold 6. Symmetry means that the two rotating arms 14 are distributed on both sides of the mold 6 at the same distance and angle, forming a balanced configuration. It helps to ensure the stability and balance of the mold 6 during rotation. Since the two rotating arms 14 support the mold 6 in a symmetrical manner, the mold 6 is less likely to tilt or sway during rotation. Secondly, the symmetrical design can also disperse the stress and load generated during the rotation of the mold 6. This means that each rotating arm 14 only needs to bear half the load, thereby improving the durability and reliability of the entire system. In addition, the symmetrical design can also simplify the installation and maintenance process of the system. Since the positions and configurations of the two rotating arms 14 are the same, installation, debugging and maintenance work can be easier.

[0048] In one possible implementation, the driving structure further includes a motor 1, a speed reducer 2, a second rotating shaft 13, a first gear 11 and a second gear 12; the motor 1 is used to drive the second rotating shaft 13 to rotate; the speed reducer 2 is used to reduce the rotation speed of the motor 1 transmitted to the second rotating shaft 13; the second rotating shaft 13 is used to drive the second gear 12; the second gear 12 is used to drive the first gear 11 to rotate; the first gear 11 is used to drive the first rotating shaft 5 to rotate.

[0049] Among them, the motor 1 is the power source of the entire driving structure. It can convert electrical energy into mechanical energy, i.e. rotational motion, to drive the second rotating shaft 13 to rotate. The speed reducer 2 is a device used to reduce the rotation speed. The speed reducer 2 usually contains one or more gear pairs, which transmit torque and reduce speed through the meshing of gears. The speed reducer 2 is used to reduce the rotation speed of the motor 1 transmitted to the second rotating shaft 13. Thus, it ensures that the rotational motion has the appropriate speed and torque when transmitted to the mold 6 or other loads.

[0050] The second rotating shaft 13 is a component in the driving structure, driven directly by the motor 1 or indirectly by the speed reducer 2, and used to drive the second gear 12 to rotate. The design of the second rotating shaft 13 usually takes into account factors such as rotation speed, torque transmission and mechanical strength. The second gear 12 is a gear connected to the second rotating shaft 13. It transmits rotational motion and torque through meshing with the first gear 11. The number of teeth and diameter of the second gear 12 are usually designed to match the first gear 11 to ensure the correct gear ratio and rotation direction.

[0051] The first gear 11 is connected to the first rotating shaft 5. When the second gear 12 rotates, it drives the first gear 11 to rotate through meshing. The rotation of the first gear 11 in turn drives the first rotating shaft 5 to rotate, thereby achieving the transmission of rotational power from the motor 1 to the first rotating shaft 5. The first rotating shaft 5 is the final output shaft of the drive structure. It is usually connected to a load that needs to rotate. The first rotating shaft 5 is driven by the rotation of the first gear 11, thereby achieving the rotational motion of the load.

[0052] By organically combining components such as the motor 1, the speed reducer 2, the second rotating shaft 13, the second gear 12, the first gear 11, and the first rotating shaft 5, the transmission of rotational power from the motor 1 to the load is achieved, and the rotational speed is adjusted in the process. In turn, the accuracy and stability of the rotational motion are improved, making the entire system more compact and efficient.

[0053] In a possible implementation, the support structure includes a shroud 9, a roller seat 18, a column frame 3 mounted on the roller seat 18, a motor bracket 17 mounted on the column frame 3, multiple sets of bearings and shaft end clamping plates, and a support plate 23 connecting the column frame 3 and the roller seat 18; the shroud 9 is used to protect the first gear 11 and the second gear 12; the motor bracket 17 is used to support the motor 1; any one of the multiple sets of bearings is used to support the first rotating shaft 5 or the second rotating shaft 13, and two bearings in any one of the multiple sets of bearings are separated by a bearing stop ring 15; the shaft end clamping plate is used to fix the first rotating shaft 5 and the second rotating shaft 13.

[0054] The support structure includes multiple components such as the shroud 9, the roller seat 18, the column frame 3, the motor bracket 17, the multiple sets of bearings, the shaft end clamping plates, and the support plate 23. These components work together to provide stable support and protection for the entire drive system. The shroud 9 is a component of the support structure, and its main function is to protect the first gear 11 and the second gear 12. During rotation, gears may produce debris or wear, and the presence of the shroud 9 can effectively prevent these debris or wear from causing harm to the surrounding environment or personnel, while also helping to maintain the cleanliness and lubrication of the gears.

[0055] The roller seat 18 is the basic part of the support structure, and the column frame 3 is the main part of the support structure, connecting the roller seat 18 and the motor bracket 17 and providing stable support for the entire system. The design of the column frame 3 usually considers rigidity and stability to ensure that there is no excessive deformation or vibration during rotation. The motor bracket 17 is part of the support structure that supports the motor 1. It is mounted on the column frame 3 and provides a stable platform to secure the motor 1. The design of the motor bracket 17 needs to consider the weight, vibration, and stability of the motor 1 during operation.

[0056] Multiple sets of bearings are used to support the first rotating shaft 5 or the second rotating shaft 13. Each set of bearings typically consists of two (e.g., the first bearing 4 and the second bearing 10) or more bearings and is separated by a bearing spacer ring 15. This helps to distribute the load on the rotating shaft, improving the stability and durability of the rotation. At the same time, the selection and installation of the bearings also need to take into account factors such as rotation speed, load, and working environment. The shaft end plate is a component used to fix the first rotating shaft 5 and the second rotating shaft 13 (e.g., in the embodiment of the present application, the shaft end plate includes the first shaft end plate 21 and the second shaft end plate 22, wherein the first shaft end plate 21 fixes the first rotating shaft 5, and the second shaft end plate 22 fixes the second rotating shaft 13). It is usually installed at the end of the rotating shaft and connected to the support structure through bolts or other fasteners. The design of the shaft end plate needs to take into account factors such as the diameter, length, and required fixing force of the rotating shaft.

[0057] The support plate 23 is a component that connects the column frame 3 and the roller seat 18. It can be in the shape of a right angle and is connected to the column frame 3 and the roller seat 18 through bolts or other fasteners. The presence of the support plate 23 enhances the rigidity and stability of the entire support structure. By combining the above components together, the support structure provides stable support and protection for the entire drive system. It ensures that the rotating shaft can rotate smoothly, while protecting important components such as the gear and the motor 1 from damage. In addition, the design of the support structure also takes into account factors such as rigidity and stability to ensure that excessive deformation or vibration does not occur during rotation.

[0058] In a possible implementation, the support structure also includes a roller 16 installed on the roller seat 18. The roller 16 is installed on the roller seat 18. The roller seat 18 is a specially designed structure for fixing and supporting the roller 16. It has mounting holes or grooves that match the roller 16 to ensure that the roller 16 can be securely installed on the roller seat 18 and remain stable during rotation. The design of the roller seat 18 also takes into account factors such as the load-bearing capacity of the roller 16 and the diameter of the rotating shaft to ensure that the roller 16 can move the entire support structure.

[0059] In a possible implementation, the roller 16 is located on the track 19, and the roller stop plate 20 is installed at both ends of the track 19 to limit the movement range of the roller 16.

[0060] The roller 16 is designed to be located on the track 19. The track 19 is a fixed structure that provides a smooth and continuous path for the roller 16 to roll along. The design of the track 19 usually takes into account the size, shape and rolling characteristics of the roller 16 to ensure that the roller 16 remains smooth and free of jolts during rolling. The material selection of the track 19 is also important, usually requiring sufficient hardness, wear resistance and corrosion resistance to withstand the long-term rolling and possible impact of the roller 16.

[0061] Optionally, the roller stop 20 is installed at both ends of the track 19. The roller stop 20 is used to limit the movement range of the roller 16, preventing the roller 16 from leaving the track 19 or exceeding the predetermined range of motion during rolling. The design of the roller stop 20 usually takes into account factors such as the size, speed of movement and required limiting force of the roller 16 to ensure that it can effectively prevent accidental movement of the roller 16.

[0062] The roller stop 20 is installed at both ends of the track 19. This means that when the roller 16 rolls to the end of the track 19, it will encounter the blocking of the roller stop 20, thereby stopping further movement. This ensures that the roller 16 rolls within the predetermined range of motion, avoiding possible collisions or damage. In addition, by sliding the roller 16 on the track 19, the distance between the two rotating arms 14 can be freely adjusted to accommodate molds 6 of different sizes.

[0063] Referring to Figure 7 The mold flipping device shown in the top view includes four roller seats 18, forming two symmetrical support structures to support two symmetrical rotating arms 14, achieving the flipping of the mold 6.

[0064] In summary, the technical scheme provided by the utility model realizes the flipping of the mold through a mechanical device, and places the center of gravity of the mold on the center of gravity of the first rotating shaft through the rotating arm structure, thereby reducing the force required for the rotation of the first rotating shaft and reducing the flipping difficulty. Among them, the rotating arm can be replaced according to different centers of gravity, improving the adaptability between the mold flipping device and the mold. In addition, the mold flipping device provided by the utility model can realize free movement through the roller, thereby freely adjusting the mold of different sizes, improving the applicability of the mold flipping device.
