Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve coil delay technology, and in particular to an electromagnetic valve coil delay control device and mold. Background Technology

[0002] Currently, integrated control of solenoid valves is divided into ordinary solenoid valves and valve islands. Ordinary solenoid valves use a one-to-one wiring and control method, which is lower in cost but complex in wiring and inconvenient to use. Valve islands use a bus control method, which requires a PLC with communication protocols, resulting in higher costs and more demanding operator skills. This makes them unsuitable for some work applications where only delayed opening and early closing of solenoid valves are required. For example, in the hot runner mold industry, the solenoid valves currently used are all one-to-one wired, with an external timing controller setting the delayed opening and early closing of each solenoid valve in the valve group. Furthermore, the timing controller must be constantly connected to the valve group to achieve continuous control during production. This not only introduces significant labor costs into the production process but also increases the demand for multiple timing controllers, thus increasing equipment costs. Utility Model Content

[0033] In one embodiment, the solenoid valve coil delay control device includes: a solenoid valve group, including: a plurality of solenoid valves 101 arranged in parallel, the solenoid valves 101 being connected in series, each solenoid valve 101 including: a solenoid valve body, a coil control board 102 and a solenoid valve coil 103, the coil control board 102 being electrically connected to the solenoid valve coil 103, the coil control board 102 being used to store the position information and delay control information of the solenoid valve 101, and the coil control board 102 being used to control the opening or closing of the solenoid valve coil 103; a main control board 104, electrically connected to the solenoid valve 101 assembled at the first position of the valve group via a wiring plug 105; and a mobile operation terminal 106, communicatively connected to the main control board 104, the mobile operation terminal 106 being used to generate operation commands for the solenoid valve 101.

[0034] Working principle:

[0035] 1. All solenoid valve coils 103 and control boards 102 are connected to the main control board 104 in a daisy-chain manner, which can connect multiple solenoid valves.

[0036] 2. The control board 102 of the solenoid valve coil 103 receives the configuration command issued by the main control board 104 and stores the position information and delay control information of the solenoid valve on the control board 102 of the solenoid valve coil 103.

[0037] 3. When the main control board receives an external trigger signal, it sends a working command through the bus. The control board 102 of the solenoid valve coil 103 controls the solenoid valve to switch direction according to the stored control information.

[0038] 4. An external handheld controller 114 can be connected to the main control board 104. The handheld controller 114 and the main control board 104 can be connected directly via wired or wireless means. The handheld controller 114 is responsible for configuring the position information and delay action information of each solenoid valve.

[0039] 5. The 115 APP on mobile phone can be used to connect to the main control board 104 wirelessly to configure and input the solenoid valve position information and delay action information.

[0040] The solenoid valve coil 103 delay control device in this application connects multiple solenoid valves 101 to the main control board 104 via a daisy-chain connection, supporting multi-channel solenoid valve expansion. This connection method eliminates the need for a complex topology, requiring only a wiring strip 105 for hardware cascading, facilitating flexible system expansion and making it suitable for scenarios requiring the control of a large number of solenoid valves.

[0041] Each solenoid valve 101 independently includes a coil control board 102 and a solenoid valve coil 103, resulting in a high degree of hardware modularity. When a solenoid valve 101 malfunctions, the corresponding module can be directly disassembled for repair or replacement without affecting the normal operation of other modules, thus reducing maintenance complexity and downtime costs.

[0042] The coil control board 102 stores point location information and delay control information, eliminating the need for real-time data transmission from the main control board 104. When the main control board 104 issues a working command, each control board can directly execute actions according to the locally stored parameters, reducing data transmission delay and improving system response speed and real-time performance, making it particularly suitable for scenarios with high control precision requirements.

[0043] This application supports setting delay control information for each solenoid valve 101 individually, and the action sequence of different solenoid valves can be flexibly adjusted according to actual process requirements.

[0044] This application supports mobile operating terminals 106 (such as handheld controllers 114 and mobile phone apps 115) to connect to the main control board 104 via wired or wireless means to configure parameters. The handheld controller 114 is suitable for close-range on-site operation, allowing direct input of location information and delay parameters near the equipment, facilitating debugging and emergency handling. The mobile phone app 115 enables remote configuration via wireless connection (such as Wi-Fi or Bluetooth), allowing operators to adjust parameters without approaching the equipment. This is particularly suitable for scenarios where equipment is installed at high altitudes, in hazardous areas, or distributed on a large scale, improving operational convenience and safety.

[0045] The main control board 104 acts as the central hub, responsible for receiving external trigger signals and issuing commands, while the solenoid valves 101 perform actions in a distributed manner. This architecture ensures the overall coordination of the system and reduces the load on the main control board 104 through distributed control, preventing the entire system from being paralyzed due to a single node failure and improving system reliability. The main control board 104 is connected to the solenoid valves 101 via a wiring connector 105, with a high degree of hardware interface standardization, compatible with different models of solenoid valve coils 103 and control boards. It also supports multiple terminals such as external handheld controllers 114 and mobile phone apps 115, and has open software interfaces, facilitating integration with other control systems (such as PLCs and industrial internet platforms) to meet the needs of diverse industrial scenarios such as intelligent factories and automated production lines.

[0046] This application allows for real-time modification of the solenoid valve's position information and delay parameters via a mobile operating terminal 106, without requiring system downtime or hardware circuit modifications. For example, when production processes are adjusted, the solenoid valve's action sequence can be quickly reconfigured via an app, shortening equipment debugging time and improving production efficiency. The hardware serial connection uses bus communication and is typically equipped with anti-interference designs (such as signal shielding and filtering circuits) to reduce the impact of electromagnetic interference in the industrial environment on data transmission, ensuring the accuracy and stability of control commands. Because each solenoid valve 101 independently stores information and features a modular design, when the system malfunctions, the faulty module can be quickly located via the mobile terminal (e.g., a solenoid valve failing to act according to the delay), facilitating targeted troubleshooting and reducing troubleshooting time and costs.

[0047] This device, through its serial modular design, local storage control, and multi-terminal interaction, achieves the advantages of "high scalability, high flexibility, and high reliability" in industrial automation control. It can meet the timing control requirements of complex processes, and is easy to operate, maintain, and upgrade. It is suitable for various industrial scenarios that require precise control of solenoid valve actions.

[0048] Furthermore, each coil control board 102 is equipped with an input socket 107 and an output socket 108. The coil control board 102 connects to the wiring strip 105 via the input interface to connect to the output interface of the previous coil control board 102 or the main control board 104. The design of the input / output sockets 108 on the coil control board 102, through a chain-connection topology, realizes the system's plug-and-play and modular expansion, supporting hot-swapping and dynamic addition and removal of nodes at any location; through fault isolation mechanisms and signal relay functions, it improves system stability and anti-interference capabilities; the standardized interface design is compatible with heterogeneous devices and communication protocols, reducing integration costs and protecting investment; segmented detection and online maintenance features shorten fault repair time and reduce production interruption losses; the compact structure and optimized wiring save space and hardware costs at the physical level, comprehensively meeting the industrial control system's requirements for flexibility, reliability, and economy.

[0049] The wiring strip 105 includes: wiring sockets 109 at both ends, which are used to connect to input sockets 107 or output sockets 108; a power cord 110 located between the wiring sockets 109 at both ends, which is electrically connected to the wiring sockets 109 at both ends; and a signal cord 111 located between the wiring sockets 109 at both ends, which is electrically connected to the wiring sockets 109 at both ends and is used to transmit control commands. The wiring strip 105 enables plug-and-play and chain-like expansion of the coil control board 102 through standardized sockets at both ends. The independent power cord 110 and signal cord 111 design ensures stable power transmission and communication, supports multi-node parallel power supply and fault isolation, and its modular structure simplifies system deployment and maintenance processes. It is compatible with heterogeneous devices and reduces wiring complexity, optimizing space utilization, cost control, and scalability, providing a flexible and reliable physical layer connection solution for industrial control systems.

[0050] In one embodiment, the solenoid valve coil delay control device includes: a solenoid valve group, including: a plurality of solenoid valves 101 arranged in parallel, the solenoid valves 101 being connected in series, each solenoid valve 101 including: a solenoid valve body, a coil control board 102 and a solenoid valve coil 103, the coil control board 102 being electrically connected to the solenoid valve coil 103, the coil control board 102 being used to store the position information and delay control information of the solenoid valve 101, and the coil control board 102 being used to control the opening or closing of the solenoid valve coil 103; a main control board 104, electrically connected to the solenoid valve 101 assembled at the first position of the valve group via a wiring plug 105; and a mobile operation terminal 106, communicatively connected to the main control board 104, the mobile operation terminal 106 being used to generate operation commands for the solenoid valve 101. The main control housing 112 and the main control board 104 are fixedly installed inside the main control housing 112. A signal interface 113 is provided on one side of the main control housing 112. The mobile operation terminal 106 is connected to the signal interface 113 through a wire. The mobile operation terminal 106 is a handheld device 114.

[0051] Furthermore, the main control board 104 is equipped with a wireless connection module, and the mobile operation terminal 106 is a mobile phone 115, which is wirelessly connected to the main control board 104. The wireless connection module between the main control board 104 and the mobile phone 115 eliminates spatial limitations, provides an intuitive interactive interface, supports multi-user collaboration and rapid emergency response, simplifies wiring and reduces maintenance costs, and, combined with data recording and software upgrade capabilities, elevates traditional industrial control to a mobile and intelligent level, providing core support for flexible operation and decision-making in industrial scenarios.

[0052] Furthermore, an indicator light is provided on the coil control board 102 to indicate the working status of the solenoid valve coil 103 corresponding to the coil control board 102.

[0053] In one embodiment, the solenoid valve coil delay control mold includes the solenoid valve coil delay control device as described above; a mold body, the mold body being provided with a number of hot runner injection ports corresponding to the solenoid valves 101, each solenoid valve 101 controlling the opening or closing of a corresponding hot runner injection port valve needle.

[0054] The mold body is equipped with a number of hot runner injection ports corresponding to the solenoid valves 101, and each solenoid valve 101 can precisely control the opening or closing of a corresponding hot runner injection port. This means that, according to different production needs, the valve needles of each hot runner injection port can be operated individually and precisely. For example, in injection molding and other processes involving hot runners, the opening and closing time and sequence of the hot runner injection ports can be accurately controlled to ensure that the plastic melt and other materials flow into the mold cavity in the preset and most suitable manner, thereby improving the quality of the molded products and reducing quality problems such as missing material, flash, and dimensional deviations caused by inaccurate hot runner control.

[0055] By combining the time-delay energizing setting function of the solenoid valve coil 103 delay control device, precise time-sequential delay control can be achieved for the opening and closing of different hot runners. In some complex molding processes, the hot runner injection ports in different locations need to be opened or closed sequentially after specific time intervals to achieve reasonable material flow and distribution within the mold. This time-delay control can better simulate or meet the requirements of complex process curves, further optimizing the entire production process and improving product consistency and yield.

[0056] Because each hot runner injection port is independently controlled by a corresponding solenoid valve 101, and the parameters such as the position sequence and delay of the solenoid valves 101 can be flexibly set, the mold can easily adapt to the production requirements of various products. Whether producing plastic products with different shapes and complex structures, or switching between different products, the working state of the hot runner can be quickly changed by simply adjusting the relevant parameters of the solenoid valves 101 through the mobile operating terminal 106, without the need for large-scale modifications to the mold structure, greatly improving the versatility of the mold and the flexibility of production.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
