When a larger output force is required to meet the mould pressing requirements, the single force multiplier cylinder may not be able to reach the required output force level, which may result in poor mould pressing effect or substandard product quality. If the cylinder diameter of the single force multiplier cylinder is increased to increase the output force, it will usually result in an increase in the overall size of the cylinder, and in the design of the glass mould pressing machine, the distance between the main shafts (or stations) is limited. Increasing the cylinder diameter may occupy more space, and the heating power will increase, resulting in increased energy consumption of the equipment, so that the distance between the main shafts (or stations) cannot meet the design requirements and the energy consumption of the equipment cannot meet the requirements. The structure of the glass mould pressing machine using single force multiplier cylinder cannot meet the requirements of distance and output force at the same time, and has certain limitations.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the following will combine the technical scheme in the utility model embodiment to make clear, complete description, obviously, the described embodiment is the part embodiment of the utility model, rather than all embodiments. Based on the embodiment of the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] As Figure 1 , Figure 2 and Figure 3 Indicated, a power mechanism of glass press machine, including support frame 1 and transmission assembly 3 with support frame 1 movably connected, transmission assembly 3 includes the connecting seat 31 with mounting surface 311;Support frame 1 is provided with three times force cylinders 2, and the output end 21 of times force cylinder 2 is all connected with mounting surface 311, wherein the output end 21 of two times force cylinders 2 is respectively located at the midpoint of the opposite two side edges of mounting surface 311 or the corner position of mounting surface 311.

[0034] Specifically, the output ends 21 of the three force multiplication cylinders 2 are arranged in a triangular structure or in a linear structure side by side; the end of the transmission assembly 3 away from the force multiplication cylinders 2 is used to connect the heating module 4, so as to heat and soften the glass and apply pressure to the softened glass material, so that the softened glass material is extruded to form a required shape, and the required glass lens is obtained after cooling. By using at least three force multiplication cylinders 2, the power mechanism can significantly improve the output force. When the spacing between the main shafts (or stations) needs to be reduced, the power mechanism thus designed can still maintain sufficient output force, easily meeting the pressure requirements of the glass mold pressing machine on the mold and the glass; further, without increasing the cylinder diameter of the cylinders, the design requirements of the spacing between the main shafts (or stations) can also be met, thereby improving the design flexibility and compactness of the glass mold pressing machine.

[0035] In addition, the output ends 21 of the two force multiplication cylinders 2 are arranged at two corner positions of the mounting surface 311, which can be opposite corners or adjacent corners of the mounting surface 311. The output ends 21 of two of the three force multiplication cylinders 2 are arranged at the midpoints of the opposite two side edges of the mounting surface 311 or at the two corner positions of the mounting surface 311, respectively, forming a stable support structure, which helps to enhance the stability of the entire power mechanism. When the output ends 21 of the two force multiplication cylinders 2 are located at the opposite two sides of the mounting surface 311 or at the two corner positions of the mounting surface 311, respectively, they can offset the generated torque from each other, thereby ensuring that the transmission assembly 3 remains stable during operation.

[0036] Uniformly distributing the output ends 21 of the two force multiplication cylinders 2 on the opposite two sides of the mounting surface 311 can ensure that the pressure is uniformly distributed on the transmission assembly 3, which can avoid damage caused by excessive local pressure and prolong the service life of the transmission assembly 3. The power mechanism can optimize the transmission path of power from the force multiplication cylinders 2 to the transmission assembly 3 through reasonable layout, which helps to reduce energy loss and improve the efficiency of the power mechanism, thereby ensuring that the glass mold pressing machine produces at a higher speed.

[0037] By using three force multiplication cylinders 2, the overall output force can be significantly improved without increasing the cylinder diameter of the individual cylinders, which can maintain the compactness of the force multiplication cylinders 2, while the stability of the power mechanism is enhanced by the synergistic effect of multiple force multiplication cylinders 2. The energy consumption of each force multiplication cylinder 2 is relatively low, and the manufacturing cost and maintenance cost of the force multiplication cylinders can also be lower. In addition, this approach also helps to improve production efficiency, thereby reducing the energy consumption and cost per unit product. Avoiding the use of large cylinders, which generally have higher energy consumption because more energy is required to maintain their operation; at the same time, the manufacturing cost and maintenance cost of large cylinders can also be higher.

[0038] In some embodiments of the present application, as Figure 4 , Figure 5 , Figure 6and Figure 7 As shown, the output ends 21 of the three force multiplication cylinders 2 form a triangular structure. Specifically, the output ends 21 of the three force multiplication cylinders 2 arranged on the support frame 1 are connected to the mounting face 311 of the connecting seat 31 of the transmission assembly 3, and are particularly designed as a triangular structure. Based on the stability principle of a triangle, it is ensured that when the force multiplication cylinders 2 work, the force can be provided in a balanced manner, so that the transmission assembly 3 is more stable when subjected to force, effectively reducing the deviation or deformation caused by uneven force.

[0039] In other embodiments, different types of lenses can be produced by adjusting the positions and angles of the force multiplication cylinders 2 to meet the production requirements of the type of lens, improving the versatility and flexibility of the equipment.

[0040] The three force multiplication cylinders 2 are arranged in a triangular structure, which significantly enhances the stability of the power mechanism. During the molding process, even if it faces a large pressure, it can maintain high precision and high stability, ensuring the quality and consistency of the product.

[0041] In some embodiments of the present application, the output ends 21 of the three force multiplication cylinders 2 are respectively located at the midpoint positions of the adjacent three side edges of the mounting face 311.

[0042] Specifically, the output ends 21 of the three force multiplication cylinders 2 are respectively connected at the midpoint positions of the adjacent three side edges of the mounting face 311, thereby forming an isosceles triangular structure; it is ensured that when the force multiplication cylinders 2 work, the force can be provided in a balanced and stable manner, so that the entire power mechanism remains highly stable when subjected to force. The uniform distribution and simultaneous action of the three force multiplication cylinders 2 ensure that the power mechanism can generate balanced output force when running, avoiding the problem of equipment damage or processing precision decline caused by uneven force, improving the stability and consistency of production.

[0043] In some embodiments of the present application, the output end 21 of one of the force multiplication cylinders 2 is arranged at the midpoint position of one side edge of the mounting face 311, and the output ends 21 of the other two force multiplication cylinders 2 are respectively arranged at the adjacent corner positions opposite to the edge.

[0044] Specifically, the output end 21 of one of the three force multiplication cylinders 2 is arranged at the midpoint of the edge of the mounting surface 311 on the side as the main power output point; at the same time, the output ends 21 of the other two force multiplication cylinders 2 are arranged at the adjacent corners on the opposite side of the midpoint edge, forming a stable isosceles triangle structure. When the three force multiplication cylinders 2 work simultaneously, the mounting surface 311 on the connecting seat 31 is acted on by the output ends 21 through the connection, and the power is stably and uniformly transmitted to the transmission assembly 3, so as to drive it to move accurately; through the reasonable layout of the force multiplication cylinders 2, the output power of the power mechanism is significantly enhanced, and the vibration or deviation caused by unbalanced power is reduced.

[0045] In some embodiments of the present application, the output ends 21 of the three force multiplication cylinders 2 are located at the adjacent triangular positions of the mounting surface 311. Specifically, compared with other layout modes, the adjacent triangular position layout can more efficiently utilize the space to ensure the maximum function and effect in a limited space, and improve the space utilization of the equipment.

[0046] In some embodiments of the present application, as shown in Figure 8 , Figure 9 and Figure 10 , the three force multiplication cylinders 2 are arranged side by side, and the output ends 21 form a linear structure. Specifically, in the power mechanism of the glass mold pressing machine, the three force multiplication cylinders 2 are arranged side by side; the three output ends 21 are located on the same straight line and jointly act on the mounting surface 311 of the transmission assembly 3. Through synchronous control, the extension and contraction actions of the three force multiplication cylinders 2 are accurately coordinated, so as to realize stable and balanced driving force output of the transmission assembly 3.

[0047] The three force multiplication cylinders 2 are arranged side by side and jointly act on the mounting surface 311, increasing the driving force of the transmission assembly 3; enabling the glass mold pressing machine to easily cope with the demand for larger pressure during the pressing process, and ensuring the smooth production of lenses. Since the output ends 21 of the three force multiplication cylinders 2 are on a straight line, the driving force of the transmission assembly 3 is balanced and stable, effectively reducing the vibration or deviation caused by unbalanced torque. The linear structure of the side-by-side arrangement makes the layout of the force multiplication cylinders 2 more compact and reasonable in space, which not only facilitates the optimization and compactness of the overall structure of the glass mold pressing machine, but also improves the space utilization of the equipment.

[0048] In some embodiments of the present application, the output ends 21 of the two force multiplication cylinders 2 are respectively located at the midpoints of the opposite two side edges of the mounting surface 311, and the output end 21 of the other force multiplication cylinder 2 is located in the middle between the two midpoints. Specifically, when the glass mold pressing machine needs to work, the three force multiplication cylinders 2 will be activated at the same time. Among them, the output ends 21 of the two force multiplication cylinders 2 are positioned at the midpoints of the opposite two side edges of the mounting surface 311, mainly responsible for providing the thrust on the opposite two sides, ensuring that the mold can be uniformly stressed during the pressing process; while the output end 21 of the third force multiplication cylinder 2 is located in the middle between the two edge midpoints, providing additional center support and thrust, further enhancing the stability and output force of the entire power mechanism. Through the reasonable layout and cooperative work of the three force multiplication cylinders 2, the power mechanism can not only generate greater output force, but also maintain better stability.

[0049] In some embodiments of the present application, the output ends 21 of the two force multiplication cylinders 2 are respectively located at the opposite two corners of the mounting surface 311, and the output end 21 of the other force multiplication cylinder 2 is located in the middle between the two corners. Specifically, the output ends 21 of the two force multiplication cylinders 2 are arranged at the opposite two corners of the mounting surface 311, providing diagonal force distribution to ensure balanced and stable force; while the output end 21 of the other force multiplication cylinder 2 is located in the middle between the two diagonal force multiplication cylinders 2, forming a horizontal one-line distribution to provide additional support and force balance. So that the three force multiplication cylinders 2 can jointly act on the mounting surface 311, and through precise synchronous control, realize stable and balanced driving force output of the transmission assembly 3. The horizontal one-line distribution of the three force multiplication cylinders 2 not only provides the required output force, but also enhances the structural stability of the entire power mechanism, so that the power mechanism can withstand greater load and impact, prolonging the service life of the equipment.

[0050] In some embodiments of the present application, the transmission assembly 3 includes a first main shaft 32 arranged on the connecting seat 31, the first main shaft 32 is connected with a second main shaft 33, the end of the second main shaft 33 is used for mounting the heating module 4, and the support frame 1 is provided with a first guide 34 and a second guide 35 respectively used for guiding the connecting seat 31 and the second main shaft 33.

[0051] Specifically, the transmission assembly 3 is the core part of the power mechanism, the first main shaft 32 and the second main shaft 33 are closely connected to ensure smooth power transmission, and the heating module 4 is mounted at the end of the second main shaft 33. Through the precise operation of the transmission assembly 3, accurate positioning and efficient power transmission of the heating module 4 can be realized. At the same time, in order to ensure the stable operation and accuracy of the transmission assembly 3, the first guide 34 and the second guide 35 are arranged on the support frame 1, respectively used for guiding the connecting seat 31 and the second main shaft 33, to ensure the stability and accuracy of the transmission assembly 3 during operation.

[0052] Through the connection of the first main shaft 32 and the second main shaft 33 and the auxiliary action of the first guide 34 and the second guide 35, the transmission assembly 3 can realize accurate control of the heating module 4, ensuring that the heating module 4 can accurately work according to the predetermined position and mode during the molding process, thereby greatly improving the manufacturing precision of the product.

[0053] In some embodiments of the present application, the first guide 34 includes first sliding blocks 341 arranged on both sides of the connecting seat 31 and first guide rails 342 arranged correspondingly with the first sliding blocks 341; the first guide rails 342 are arranged in connection with the support frame 1; and the first sliding blocks 341 are in sliding connection with the first guide rails 342. Specifically, the first guide rails 342 are fixed on the support frame 1 to provide a stable sliding track for the first sliding blocks 341; when the connecting seat 31 starts to move under the driving of the power mechanism, the first sliding blocks 341 slide along the first guide rails 342 to ensure the stable movement of the connecting seat 31 and effectively prevent vibration or shaking during the movement, thereby ensuring the accuracy and stability of the operation of the power mechanism; and the accuracy of the path and direction of the connecting seat 31 during the movement is maintained.

[0054] In some embodiments of the present application, the second guide 35 includes second sliding blocks 351 arranged on both sides of the second main shaft 33 and second guide rails 352 arranged correspondingly with the second sliding blocks 351; the second guide rails 352 are arranged in connection with the support frame 1; and the second sliding blocks 351 are in sliding connection with the second guide rails 352. Specifically, the second guide rails 352 are fixed on the support frame 1 to provide a reliable sliding track for the second sliding blocks 351; when the second main shaft 33 starts to move under the driving of the force multiplier cylinder 2, the second sliding blocks 351 slide along the second guide rails 352 to ensure the stable and accurate movement path of the second main shaft 33, thereby ensuring the efficient operation of the power mechanism. Through the sliding connection of the second sliding blocks 351 and the second guide rails 352, the second guide 35 effectively reduces the shaking or deviation of the second main shaft 33 during the movement, thereby significantly improving the stability of the overall structure. The power mechanism can work more stably, and the errors caused by vibration or shaking are reduced.
