DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2The utility model provides a technical solution: a bolt casting mold with a high yield rate, including a bottom plate 1. When discussing this structural design in detail, we must first clarify that the bottom plate 1, as a basic component, plays a vital role. On it, there are two core support components, a first support plate 2 and a second support plate 3. The two support plates are not placed randomly, but are precisely designed and laid out to ensure the stability and functionality of the structure.

[0018] Specifically, the first support plate 2 and the second support plate 3 are parallel to each other on the bottom plate 1. This parallel layout not only ensures the symmetry of the structure, but also achieves uniform distribution of force in mechanics. When external force acts on the entire structure, this parallel layout can effectively disperse the force to the two support plates, thereby reducing the burden of a single support plate and improving the bearing capacity of the overall structure.

[0019] Let's analyze the advantages of this parallel layout in depth. First, the parallel layout can maximize the use of the space of the support plate, making the entire structure more compact and efficient. Second, the parallel layout can also reduce the stress concentration phenomenon in the structure. In mechanics, stress concentration often leads to local damage of the structure, and the parallel layout can effectively avoid this problem.

[0020] In addition, the material and size of the first support plate 2 and the second support plate 3 are also carefully selected. Usually, in order to ensure the stability and strength of the structure, these support plates will use high-strength and high-rigidity materials, such as steel or alloys. As for the size, it needs to be reasonably designed according to the specific application scenario and load requirements.

[0021] In practical applications, this parallel layout of support plate structure is widely used in various fields. For example, in the field of construction, it can be used as a support structure for buildings such as bridges and high-rise buildings; in the field of machinery, it can be used as a base or bracket for equipment such as machine tools and robots; in the field of aerospace, it plays an indispensable role.

[0022] In short, the first support plate 2 and the second support plate 3 are arranged on the bottom plate 1 in parallel. This structural design not only has high stability and bearing capacity, but also has a wide range of application prospects. It is an important achievement in the field of modern engineering technology and provides us with solid and reliable support.

[0023] A first fixed plate 4, a second fixed plate 5, a third fixed plate 6 and a fourth fixed plate 7 are arranged from top to bottom between the first support plate 2 and the second support plate 3. A guide shaft 8 is arranged between the first fixed plate 4 and the fourth fixed plate 7, and the guide shaft passes through the second fixed plate 5 and the third fixed plate 6; a first linear bearing 9, a second linear bearing 10 and a third linear bearing 11 are slidingly arranged on the guide shaft 8, the first linear bearing is arranged on the upper side of the second fixed plate 5, the second linear bearing 10 is arranged on the upper side of the third fixed plate 6, and the third linear bearing 11 is arranged on the upper side of the fourth fixed plate 7; a first movable plate 12 is arranged on the first linear bearing 9, a second movable plate 13 is arranged on the second linear bearing 10, and a third movable plate 14 is arranged on the third linear bearing 11. In modern industrial production, mold design and manufacturing occupy a vital position. They are the key factors to achieve mass production of products, ensure product quality and reduce production costs. Among them, the fixed plate and the movable plate, as the core components of the mold system, play a pivotal role. Now, we will explore in depth the design and application of molds on the fixed plate and the movable plate.

[0024] First, let's look at the fixed plate part. The second fixed plate 5, the third fixed plate 6 and the fourth fixed plate 7 are fixed support components in the mold system, and are all equipped with high-precision fixed molds 15. These fixed molds 15 are precisely processed and strictly tested to ensure the accuracy and stability of the mold. In practical applications, they play an important role in supporting, positioning and fixing the mold.

[0025] For example, in the injection molding process, the precise design and manufacture of the fixed mold 15 has a decisive influence on the appearance quality, dimensional accuracy and molding efficiency of the product. By optimizing the structural design and material selection of the fixed mold 15, the molding quality and production efficiency of the product can be significantly improved.

[0026] Next, we focus on the moving plate part. The first moving plate 12, the second moving plate 13 and the third moving plate 14 are responsible for the opening and closing operations of the mold in the mold system. The lower sides of them are all equipped with moving molds 16, which work closely with the fixed mold 15 to complete the molding process of the product.

[0027] The design and manufacture of the moving mold 16 also require extremely high precision and stability. They need to have good wear resistance, high temperature resistance and corrosion resistance to adapt to the high temperature and high pressure production environment. In addition, the closing force and speed of the moving mold 16 are also key factors affecting product quality and production efficiency.

[0028] In order to achieve efficient and stable operation of the mold, modern mold systems usually use advanced control systems and drive technologies. By accurately controlling the opening and closing speed and closing force of the moving plate, the precise matching of the moving mold 16 and the fixed mold 15 can be ensured to avoid defects or defective products.

[0029] According to statistics, optimizing mold design and manufacturing can significantly reduce production costs, improve production efficiency and product quality. Therefore, more and more companies are beginning to pay attention to the research and development and application of mold technology.

[0030] In short, the design and manufacture of molds on the fixed plate and the movable plate are the core links of the mold system. By optimizing the mold design and manufacturing, the molding quality and production efficiency of the product can be significantly improved and the production cost can be reduced.

[0031] The key mechanical structure provided in the present invention involves three moving plates: a first moving plate 12 , a second moving plate 13 and a third moving plate 14 , as well as a crucial threaded rod 17 and a driving device 18 .

[0032] First, let's have a clear understanding of the three moving plates. They are usually arranged in parallel, each carrying a different workload or tool, and used to perform various precise operations. In order to ensure that these moving plates can move according to the predetermined trajectory, we use a precise thread design. Specifically, the middle of the first moving plate 12, the second moving plate 13 and the third moving plate 14 are all provided with a threaded hole that penetrates, and these holes are precisely machined to ensure perfect cooperation with the threaded rod 17.

[0033] Next, let's focus on the threaded rod 17. This rod is not only the key to connecting the three moving plates, but also the power source for their movement. The upper end of the threaded rod 17 extends through the first fixed plate 4 and is closely connected to the drive device 18. The drive device 18 can be an electric motor, a pneumatic device, or a hydraulic device, which is selected according to the specific application scenario and needs. When the drive device 18 is started, it drives the threaded rod 17 to rotate. Since the threaded rod 17 is tightly matched with the threaded holes on the three moving plates, when the threaded rod 17 rotates, the three moving plates will move up and down precisely along the threaded rod 17.

[0034] The advantage of this design is its high accuracy and reliability. By accurately controlling the speed and direction of rotation of the drive device 18, we can achieve precise control of the speed and direction of movement of the three moving plates. This control accuracy is crucial for many precision manufacturing and assembly tasks. For example, in the semiconductor manufacturing process, a small deviation may cause product failure or performance degradation. By using this mechanical structure based on threaded rods and moving plates, we can ensure that each step is carried out according to the predetermined trajectory, thereby greatly improving the product yield and performance stability.

[0035] In addition, this design has good flexibility and scalability. By adjusting the diameter and pitch of the threaded rod 17 and the size and number of the moving plates, we can easily adapt to different work requirements and scenarios. For example, if we need to increase or decrease the workload or the number of tools, we only need to increase or decrease the number of moving plates accordingly. This flexibility makes this mechanical structure have a wide range of application prospects in automated assembly lines.

[0036] In conclusion, the mechanical structure based on threaded rods and moving plates has important application value in the field of modern mechanical manufacturing. By precisely controlling the moving speed and direction of the three moving plates, we can achieve highly accurate manufacturing and assembly tasks. At the same time, this design also has good flexibility and scalability, which can adapt to different work needs and scenarios.

[0037] Specifically, in the field of modern mechanical design and manufacturing, precise adjustment and adaptation of equipment are crucial. Especially in some occasions that require precise control, such as high-precision processing, measuring equipment or automated production lines, a small adjustment of each component may have a significant impact on the performance of the entire system. For this reason, designers usually use various adjustment devices to ensure the precise operation of the equipment.

[0038] Take a certain high-precision processing equipment as an example. Its base plate 1, as the basic supporting component of the entire equipment, is not only required to be stable and reliable, but also highly adjustable. In order to meet this requirement, a height adjustment plate is specially designed at the lower end of the base plate 1.

[0039] The height adjustment plate is a delicate mechanical device, which is made of high-strength alloy material and has a precision-machined surface to ensure that the contact surface with the bottom plate 1 is flat and smooth, thereby reducing friction and wear. A precision spiral lifting mechanism is installed inside the adjustment plate. By rotating the adjustment knob, the height of the adjustment plate can be accurately controlled, thereby achieving fine-tuning of the bottom plate 1.

[0040] In practical applications, the height adjustment plate plays a significant role. When the equipment needs to be adjusted horizontally, the operator only needs to gently rotate the adjustment knob to raise or lower the adjustment plate, thereby achieving accurate height adjustment of the bottom plate 1. This fine-tuning method is not only simple and quick to operate, but also has high adjustment accuracy, which can ensure that the equipment maintains a stable horizontal state during operation.

[0041] In addition, the height adjustment plate has some other advantages. For example, it can be customized according to the needs of different equipment to adapt to different working environments and installation conditions. At the same time, the height range of the adjustment plate is wide, which can meet the different requirements of different equipment for the base plate height. In addition, the structural design of the adjustment plate is reasonable, with good load-bearing capacity and stability, which can ensure that the equipment maintains stable performance during long-term operation.

[0042] It is worth mentioning that the height adjustment plate is widely used in the modern industrial field. In addition to high-precision processing equipment, it is also widely used in various occasions that require precise control and adjustment, such as measuring equipment, automation equipment, and testing equipment. With the continuous development of industrial technology, the application prospects of the height adjustment plate will be broader.

[0043] In summary, the height adjustment plate at the lower end of the base plate 1 is an ingenious and practical mechanical device, which can achieve precise adjustment of the equipment by precisely controlling the height of the base plate. In the modern industrial field, the application of the height adjustment plate has become indispensable, which provides a strong guarantee for the stable operation and performance improvement of the equipment.

[0044] Specifically, in the field of modern mechanical manufacturing, in order to ensure the precise movement and stable operation of the equipment, the design of the auxiliary sleeve and the auxiliary guide shaft is very important. In this article, we will deeply explore the function, design and application of the auxiliary sleeve 19 and the auxiliary guide shaft 20 longitudinally arranged inside the auxiliary sleeve 19 which are all arranged on the first moving plate 12, the second moving plate 13 and the third moving plate 14.

[0045] First, we need to understand the basic concept of auxiliary bushing 19. Auxiliary bushing 19 is a mechanical device that is usually used to provide additional support and guidance to ensure that the moving plate can remain accurate and stable during movement. These bushings are usually made of wear-resistant materials such as high-strength alloy steel or stainless steel to withstand frequent friction and stress.

[0046] In the device described herein, auxiliary sleeves 19 are provided throughout the first moving plate 12, the second moving plate 13 and the third moving plate 14. These sleeves not only provide the necessary support, but also ensure the precise guidance of the moving plates during movement through the auxiliary guide shafts 20 provided longitudinally inside. The auxiliary guide shafts 20 are usually designed using precision machining technology to ensure that their surfaces are smooth and their dimensions are accurate, thereby minimizing friction and deviation of the moving plates during movement.

[0047] To better understand the role of these bushings and guide shafts, we can consider a practical application scenario. Suppose this is a high-precision CNC machine tool, whose moving plate needs to move precisely in multiple directions for machining operations. In this case, the presence of auxiliary bushings 19 and auxiliary guide shafts 20 will ensure that the moving plate can maintain stable performance when moving quickly or under heavy loads. This stability is essential to ensure machining accuracy and extend the life of the equipment.

[0048] In addition, according to some empirical studies, the design of auxiliary sleeves and auxiliary guide shafts has a significant impact on improving the overall performance of the equipment. For example, a study on CNC machine tools found that by optimizing the design of auxiliary sleeves and guide shafts, the failure rate of the equipment can be significantly reduced and the processing accuracy can be improved. These improvements not only improve the production efficiency of the equipment, but also reduce maintenance costs.

[0049] In summary, the auxiliary sleeves 19 and the auxiliary guide shafts 20 longitudinally arranged inside the first moving plate 12, the second moving plate 13 and the third moving plate 14 play a vital role in the field of modern mechanical manufacturing. They ensure the stability and processing accuracy of the equipment by providing precise support and guidance. With the continuous advancement and innovation of technology, the design of these sleeves and guide shafts will continue to be optimized and improved to meet higher production requirements.

[0050] Specifically, in the field of modern industrial machinery, the drive device plays a vital role. Take our precision machinery as an example, the drive device 18, which consists of a well-designed bracket and a high-efficiency drive motor, works together to provide stable and powerful power.

[0051] First, let's take a look at the bracket part of this device. The bracket is cleverly designed and installed on the upper side of the first fixing plate 4. It is like a solid guardian, ensuring the stability and safety of the entire drive device. This bracket is made of high-strength material and can withstand shocks and vibrations under various complex working conditions, ensuring the stable operation of the machine.

[0052] Next, we focus on the drive motor. As the power source of the entire device, the drive motor is installed on the upper side of the bracket, and its drive end is closely connected to the threaded rod 17. This drive motor adopts advanced electromagnetic technology and precise control system, and has the characteristics of high efficiency, low noise and long life. It can accurately control the output torque and speed according to the working requirements of the machine to ensure the efficient operation of the machine.

[0053] In practical applications, when the drive motor is started, it transmits power to the threaded rod 17 through the drive end. The threaded rod 17 rotates under the drive of the motor, driving the mechanism connected to it to work. This transmission method has the advantages of simple structure, high transmission efficiency, high positioning accuracy, etc., and is widely used in various mechanical systems that require precise control.

[0054] It is worth mentioning that this drive device also has intelligent protection function. Through built-in sensors and control systems, it can monitor the working status of the motor in real time, such as temperature, current, voltage and other parameters. Once an abnormal situation is found, such as overload, overheating, etc., the control system will immediately initiate protection measures, such as reducing the motor speed, cutting off the power supply, etc., to avoid mechanical damage and safety accidents.

[0055] In summary, the drive device 18, which consists of a bracket and a drive motor, has become an indispensable part of the modern industrial machinery field with its stable and reliable structure, efficient power output and intelligent protection function. It plays a vital role in the fields of machinery manufacturing, automated production lines and precision instruments.

[0056] Specifically, in the modern industrial field, the design and optimization of mechanical transmission systems have always been the focus of engineers. Especially under the requirements of high-precision and high-efficiency transmission, the importance of couplings as key components connecting drive motors and transmission components such as threaded rods is self-evident. In this article, we will deeply explore the design, function and application of couplings between the drive end of the drive motor and the threaded rod in the transmission system.

[0057] First, let's understand the basic concept of couplings. A coupling is a device used to connect two shafts in different mechanisms, the driving shaft and the driven shaft, to transmit torque or compensate for the offset between the shafts. In the transmission system between the drive motor and the threaded rod, the coupling acts as a bridge to ensure that the power output by the motor can be smoothly and efficiently transmitted to the threaded rod, thereby driving its rotation.

[0058] So why is it necessary to set a coupling between the drive end of the drive motor and the threaded rod? This is mainly due to some challenges in the actual transmission process. First, due to factors such as installation errors, temperature changes or mechanical vibrations, the axis between the drive motor and the threaded rod may be offset. At this time, the coupling can absorb these offsets through its internal elastic elements or compensation mechanisms, thereby protecting the transmission system from damage. Secondly, the coupling can also reduce the impact load generated when the motor starts or stops to a certain extent, extending the service life of the transmission system.

[0059] In practical applications, there are many types of couplings, such as rigid couplings, elastic couplings, diaphragm couplings, etc. These different types of couplings have their own characteristics in structure, performance and application scenarios. For example, rigid couplings are suitable for occasions with high speed and large torque transmission, while elastic couplings are more suitable for occasions that need to compensate for inter-axis offset and reduce impact loads. Therefore, when selecting a coupling, it is necessary to make comprehensive considerations based on the specific transmission requirements and working environment.

[0060] In addition, it is worth noting that the installation, commissioning and maintenance of the coupling are also key links to ensure its normal operation. During the installation process, it is necessary to ensure that the axis of the coupling is consistent with the axis of the motor and the threaded rod to avoid excessive deviation. During the commissioning process, it is necessary to adjust the parameters such as the preload and clearance of the coupling to ensure the accuracy and stability of its transmitted torque. During the maintenance process, it is necessary to regularly check the wear and deformation of the coupling and replace the damaged parts in time to ensure the normal operation of the transmission system.

[0061] In summary, setting a coupling between the driving end of the drive motor and the threaded rod is an indispensable part of the transmission system design. By properly selecting and using the coupling, the efficient and stable operation of the transmission system can be ensured, production efficiency can be improved, and maintenance costs can be reduced.

[0062] Working principle: When the utility model is working, fixed molds are set on the second fixed plate 5, the third fixed plate 6 and the fourth fixed plate 7, and movable molds 16 are set on the lower sides of the first movable plate 12, the second movable plate 13 and the third movable plate 14. The corresponding fixed molds 15 and movable molds 16 are used in combination to process multiple lock tongues at the same time, and the threaded rod 17 is driven by a driving motor to rotate, and the movable molds 16 on the first movable plate 12, the second movable plate 13 and the third movable plate 14 are driven to move through the action of the thread. At the same time, the guide shaft 8 has a positioning and guiding function, and there is no need to manually adjust the movable mold 16, thereby improving the processing effect of the lock tongue.
