DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] A complete embodiment of this solution is described below:

[0024] In this example, we will detail a core block locking structure designed to precisely control the position and locking of core blocks in industrial applications:

[0025] The core block locking structure includes a drive motor (1) and a swing arm seat (4) for achieving precise core block positioning and locking. The drive motor (1) is connected to a transmission pull rod (3) via a flange (2) thereon, while the two ends of the swing arm seat (4) are respectively connected to the transmission pull rod (3) and the core block seat (7). This design allows the locking and releasing of the core block to be controlled by the rotational motion of the motor, thereby achieving automation and precise control.

[0026] In this embodiment, we will explore in detail the design of the triangular swing arm seat (4) and its role in the core block locking structure, especially how it provides stability and strength, and how its unique geometry and material selection can optimize performance.

[0027] Design advantages of the triangular swing arm seat (4): The design of the triangular swing arm seat (4) utilizes the inherent stability of the triangle, which is a basic geometric principle that the triangular structure can evenly disperse the force when subjected to external forces and reduce structural deformation. This stability is essential for withstanding repeated mechanical stress and dynamic loads. The triangular structure effectively disperses the forces acting on the swing arm seat through the geometric configuration of its three sides and corners, reducing stress concentration points and thus reducing the risk of material fatigue and fracture. When subjected to force, the triangular swing arm seat (4) is able to maintain its shape and position, which is necessary for accurately controlling the position and locking state of the core block. The rigid structure ensures that there will be no unnecessary displacement or deformation during operation.

[0028] Material Selection: High-strength steel offers exceptional strength and durability for applications requiring high loads and frequent use. Its high yield and tensile strengths make it an ideal choice for swingarm mounts. Aluminum alloy is a lightweight yet strong material with good corrosion resistance and machinability. Using aluminum alloy reduces structural weight and improves energy efficiency without sacrificing strength.

[0029] Articulation of the first connecting hole (41): The swing arm seat (4) is articulated with the transmission rod (3) through the first connecting hole (41). This design allows the swing arm seat to swing freely within a certain angle range. The articulation provides smooth movement and precise control while reducing wear and maintenance requirements.

[0030] Fixing of the second connecting hole (45): The other side of the swing arm seat is fixed to the core block seat (7) through the second connecting hole (45). This fixing method ensures the overall stability of the structure and prevents any unnecessary movement during operation.

[0031] The swing arm (43) connects the first connection hole (41) and the second connection hole (45) to form the main part of the swing arm base (4). The design and material selection of the swing arm are intended to ensure sufficient durability and elasticity when subjected to repeated mechanical stress. The geometry and size of the swing arm (43) are optimized to provide the best force transmission efficiency and minimize deformation.

[0032] A driving end (42) and a force-applying end (44) are fixed on both sides of the swing arm seat (4). These two end points are connected to the transmission pull rod (3) and the core block seat (7) respectively. The driving end (42) is responsible for receiving power from the drive motor (1), while the force-applying end (44) is responsible for transmitting power to the core block seat (7) to achieve the locking of the core block. The design of the end points takes into account the efficiency of force transmission and the stability of the structure.

[0033] A core cutter (5) is provided in the middle of the core block seat (7). This is a key component used to clamp the core cutter hole (6) during operation. The design of the core cutter takes into account the matching accuracy between it and the core cutter hole (6), ensuring stability and reliability during the locking process. The material selection of the core cutter (5) takes into account hardness and wear resistance, and is generally made of cemented carbide or tool steel.

[0034] The core block seat (7) is fixed by the wall panel (8), which provides a solid support point to ensure that the core block seat will not move when subjected to load. The design and installation location of the wall panel (8) are carefully selected to ensure the stability and durability of the entire structure. The material and size of the wall panel (8) are designed with consideration given to load-bearing capacity and ease of installation.

[0035] The core of the core block locking structure lies in the precise control capability of the drive motor (1), which works in conjunction with the transmission pull rod (3) to achieve precise operation of the core block seat (7) and the core knife (5). This design not only improves the degree of automation of the operation, but also ensures the reliability and repeatability of the locking process.

[0036] The drive motor (1) is the power source of the entire system, and its precise control ability is crucial for achieving precise locking. The motor is connected to the transmission pull rod (3) through a flange (2), ensuring efficient force transmission. The selection of the motor takes into account its torque output, speed range, and control accuracy to meet the requirements under different working conditions.

[0037] The transmission pull rod (3) is a key component connecting the drive motor (1) and the swing arm seat (4). Its design takes into account strength, rigidity, and wear resistance. The material selection and surface treatment of the pull rod are aimed at ensuring durability under high loads and frequent operations. The connection between the pull rod and the flange (2) adopts a high-precision fit to reduce gaps and errors during transmission.

[0038] The swing of the swing arm seat (4) is converted from the linear motion of the transmission pull rod (3). The design of the swing arm seat (4) allows it to swing freely within a certain angle range. This swing mechanism enables the core block seat (7) and the core cutter (5) to precisely clamp or release the core cutter hole (6). The swing angle and speed of the swing arm seat (4) can be adjusted through the control parameters of the drive motor (1).

[0039] The designs of the core block seat (7) and the core cutter (5) take into account their collaborative work during locking and releasing. The core cutter (5) clamps the core cutter hole (6) during operation, while the core block seat (7) achieves precise control of the core cutter (5) through the swing of the swing arm seat (4). This design ensures uniform distribution of the locking force and stable positioning of the core block.

[0040] In this embodiment, we will describe in detail the design and function of the second connection hole (45) in the core block locking structure. This is a key mechanical component that allows precise and flexible connection between the core block seat (7) and the swing arm seat (4). The second connection hole (45) is designed with a rectangular structure, which provides a large contact area, helping to enhance the stability and load-bearing capacity of the connection. The rectangular shape also facilitates precise positioning and alignment. A sliding mechanism is designed inside the second connection hole (45), which allows the core block seat (7) to perform a limited sliding motion within the connection hole. This design enables the core block seat (7) to be fine-tuned within a certain range to adapt to different installation requirements or adjustments. The material selection of the second connection hole (45) takes into account wear resistance and strength, usually using high-strength engineering plastics or hardened steel to ensure durability and reliability during long-term operation.

[0041] When the core block needs to be locked, the drive motor (1) starts and drives the transmission pull rod (3) to move, thereby causing the swing arm seat (4) to swing, pushing the core block seat (7) and the core cutter (5) to clamp the core cutter hole (6). This process can be precisely controlled by the control unit of the motor, including the magnitude, speed, and direction of the force. When the core block needs to be released, the drive motor (1) performs a reverse operation, causing the core block seat (7) and the core cutter (5) to release the core cutter hole (6), thereby achieving the rapid release of the core block.

[0042] The design of the entire system takes into account the coordination among various components, including the interaction of the drive motor (1), the transmission pull rod (3), the swing arm seat (4), the core block seat (7), and the core cutter (5). This coordination ensures the stability and reliability of the system under various working conditions.

[0043] This core block locking structure is applicable to a variety of industrial applications, such as mold manufacturing, automation equipment, machining, etc., especially in situations where precise control of the core block position and locking force is required. For example, in injection molds, the precise positioning and locking of the core block are crucial for ensuring product quality. In an automated assembly line, this structure can achieve rapid and precise core block replacement, improving production efficiency.

[0044] The long-term stable operation of the core block locking structure depends on regular maintenance and servicing. These activities help prevent failures, reduce downtime, improve production efficiency, and extend the overall service life of the equipment.

[0045] First, visually inspect the connection points of the transmission pull rod (3) and the swing arm seat (4) to confirm whether all fasteners are secure and show no signs of looseness or damage. Use appropriate measuring tools, such as calipers or gauges, to check the wear condition of the connection part to ensure the stability and safety of the connection. If looseness is found, immediately re-tighten it with the specified torque to avoid failures during operation.

[0046] Check the mating accuracy when the core cutter (5) is inserted into the core cutter hole (6) to ensure that the locking force is uniform and consistent. Evaluate the wear degree of the core cutter (5) and the core cutter hole (6), and make adjustments or replacements if necessary to maintain the reliability of the locking. Remove any debris or foreign objects inside the core cutter (5) and the core cutter hole (6) to prevent damage during the locking process.

[0047] Based on the manufacturer's recommendations and actual usage, formulate a reasonable lubrication cycle. Lubricate the hinge points of the swing arm seat (4), the bearings of the drive motor (1), and other moving parts. Select a suitable lubricant, considering the working environment and temperature conditions, to ensure the lubrication effect.

[0048] Regularly check the operating status of the motor, including current, voltage, and temperature rise. Clean the motor's cooling system to ensure good heat dissipation and avoid overheating. Check the motor's cables and connectors to ensure the security and reliability of the connections. Conduct regular safety checks, including the emergency stop function and the integrity of the protective devices. Perform performance tests to ensure that the locking structure can operate stably under various working conditions. Record the details of each maintenance and servicing, including inspection results, replaced components, and measures taken. Track the problems found to ensure timely resolution, and analyze the causes of the problems to prevent recurrence.

[0049] When designing the chip locking structure, safety features are also an important consideration. For example, the drive motor (1) can be equipped with overload protection to prevent the motor from being damaged due to overload. In addition, the design of the chip seat (7) and the chip cutter (5) should take into account the safety of the operator to avoid accidental injuries during operation.

[0050] The chip locking structure should be able to operate stably under various environmental conditions, including different temperatures, humidities, and possible chemical corrosion environments. Therefore, material selection and surface treatment should take these factors into account to ensure the corrosion resistance and wear resistance of the structure.

[0051] Through this carefully designed chip locking structure, precise control and locking of the chip can be achieved, improving production efficiency and product quality. The design of this structure takes into account the simplicity of operation, the convenience of maintenance, and the reliability of the system, making it an ideal choice for applications that require precise control of chip locking.

[0052] When designing the chip locking structure, it is very important to consider the special requirements of different industrial applications. The following are some key factors that need to be particularly concerned about during the design process:

[0053] At the initial stage of design, a detailed analysis of the application environment is required, including factors such as temperature, humidity, dust, and chemical corrosiveness, to ensure that the structural materials and surface treatment can adapt to these environmental conditions. Select appropriate materials and design an appropriate safety factor according to the load and force exerted on the chip in industrial applications. For applications with high loads, high-strength or high-rigidity materials may be required. For industrial applications that require high precision and high repeatability, such as precision machining or automated assembly lines, the design should ensure the precise control and stability of the locking structure.

[0054] The simplicity of operation should be considered during the design to ensure that the operators can lock and release the pellets easily and quickly, reducing operation errors and improving work efficiency. Design a structure that is easy to maintain and service so that necessary inspections, cleaning, and repairs can be carried out quickly after long-term operation. Consider the compatibility with other industrial equipment to ensure that the locking structure can be easily integrated into the existing production line or system. Incorporate safety features into the design, such as an emergency stop mechanism, overload protection, and anti-misoperation protection, to ensure the safety of the operators and the equipment. Select durable materials and designs to improve the reliability and service life of the structure and reduce production interruptions caused by failures. While meeting all technical requirements, consider cost-effectiveness to ensure that the design solution is economically viable and provides a good return on investment.

[0055] Comply with relevant industrial regulations and standards to ensure that the design meets industry specifications and certification requirements. Consider the environmental impact in the design, select recyclable or environmentally friendly materials, and reduce energy consumption and waste generation. Adopt a modular design concept so that some components in the structure can be easily replaced or upgraded to adapt to the changing industrial needs.
