Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machine control, in particular to a distributed IO control system for an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is a main molding device for thermoplastics or thermosetting plastics to be made into plastic products of various shapes using plastic forming molds. As disclosed in the invention application of publication number CN115946312A, it is exactly a similar injection molding machine.

[0003] like Figure 1 As shown, existing injection molding machines typically utilize centralized I / O control, where a controller with an I / O module is installed in a power distribution cabinet, which is then located within the machine's main body. Terminals or connectors connect these components 21 to components located outside the power distribution cabinet. These components 21, including but not limited to sensors and actuators, are distributed throughout the machine's main body, fixed platen, movable platen, and injection block. However, this model is only suitable for equipment with a small number of I / O points and simple control. For complex, large-scale injection molding machines, it has numerous shortcomings, the main issues being the following:

[0004] (1) With a centralized IO design, the controller requires many external components 21, which makes the design and installation of the distribution cabinet complicated. It not only causes poor heat dissipation of the distribution cabinet, but also makes subsequent maintenance cumbersome.

[0005] (2) All components 21 in each area of ​​the injection molding machine need to be connected to the IO module of the controller through separate cables, which not only consumes a large amount of wire, but also increases the number of IO expansion modules, thereby further increasing the complexity of the distribution cabinet.

[0006] (3) To reduce the difficulty of transportation, large injection molding machines need to be disassembled into different areas first and then assembled at the destination. During the assembly process, the components 21 in each area need to be connected to the cables on the IO module through terminal blocks or connectors. The extensive use of terminal blocks and connectors will not only increase material and labor costs, but also increase the probability of signal interference caused by cables, and at the same time increase the cost of equipment debugging, line checking and maintenance.

[0007] Therefore, there is still room for improvement in the existing injection molding machine IO control system. Utility Model Content

[0008] In response to the shortcomings of the existing technology, the utility model provides a distributed IO control system for injection molding machines, which can not only simplify the distribution cabinet and improve the heat dissipation performance of the distribution cabinet, but also reduce the length of cables and save costs. At the same time, it can reduce signal interference and improve the convenience of early debugging and later modification and maintenance.

[0009] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0010] A distributed IO control system for an injection molding machine includes a main control box, a fixed mold substation box, and a movable mold substation box. The main control box, the fixed mold substation box, and the movable mold substation box are respectively arranged in the body area, the fixed mold plate area, and the movable mold plate area of ​​the injection molding machine. The main control box is provided with a main control board, and the main control board has a built-in main IO module. The main IO module is coupled to a number of external components. The fixed mold substation box is provided with a fixed mold connection module, which is coupled to at least one fixed mold IO module, and the fixed mold IO module is coupled to a number of external components. The movable mold substation box is provided with a movable mold connection module, which is coupled to at least one movable mold IO module, and the movable mold IO module is coupled to a number of external components. The main control board, the fixed mold connection module, and the movable mold connection module are coupled in sequence through signal cables to realize signal transmission among the three.

[0011] Preferably, the main control board is provided with a CPU module and a bus interface for the injection molding machine control system.

[0012] Preferably, the external component one includes a sensor and a hydraulic valve installed in the fuselage area.

[0013] Preferably, the second external component includes a sensor and a hydraulic valve installed in the fixed template area.

[0014] Preferably, the third external component includes a sensor and a hydraulic valve installed in the movable template area.

[0015] Preferably, an injection substation box is further included, which is arranged in the injection seat area of ​​the injection molding machine. An injection connection module is arranged in the injection substation box, and the injection connection module is coupled with at least one injection IO module. The injection IO module is coupled with a number of external components. The injection connection module is coupled to the dynamic mold connection module through a signal cable.

[0016] Preferably, the external component four includes a sensor and a hydraulic valve installed in the injection seat area.

[0017] Preferably, the injection connection module is further coupled to a temperature module, and the temperature module is coupled to a temperature measuring module arranged on the injection seat barrel.

[0018] Preferably, a power supply is provided in the main control box, and the power supply is electrically connected to the main control board, the fixed mold connection module, the movable mold connection module and the injection connection module to supply power to the main control board, the fixed mold connection module, the movable mold connection module and the injection connection module respectively.

[0019] Preferably, the signal cable is an EtherCat bus.

[0020] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0021] 1. The distributed IO design allows the IO modules on the original controller to be expanded to various areas of the injection molding machine, thereby reducing the number of external components required for a single IO module. This simplifies the layout of the power distribution cabinet, improves heat dissipation performance, and increases the convenience of early installation and commissioning as well as subsequent modifications and maintenance.

[0022] 2. The distributed I / O design allows I / O module expansion with just one signal cable and one power cord. External components in each area can be directly connected to the corresponding expansion I / O module via short cables, effectively reducing signal cable length and interference.

[0023] 3. Because the external components in each area are directly connected to the corresponding expansion IO module via short cables, when assembling the injection molding machine, only the signal cables and power cables need to be connected. Compared with centralized IO control systems, this can significantly reduce the use of terminal blocks and connectors, not only reducing material and labor costs, but also further improving the stability of signal transmission, while further reducing the costs of early debugging and subsequent modification and maintenance.

[0027] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0028] like Figure 2 As shown, this embodiment discloses a distributed I / O control system for an injection molding machine, comprising a main control box 1, a fixed mold substation box 2, and a movable mold substation box 3. The main control box 1, the fixed mold substation box 2, and the movable mold substation box 3 are respectively disposed within the body, fixed mold plate, and movable mold plate areas of the injection molding machine. Specifically, the main control box 1 is provided with a main control board 4, which houses a CPU module, a bus interface, and a main I / O module 5 for the injection molding machine control system. The main I / O module 5 is coupled to a number of external components 6, including, but not limited to, a number of sensors and hydraulic valves installed within the body area.

[0029] A fixed mold connection module 7 is provided in the fixed mold substation box 2, and the fixed mold connection module 7 is coupled to at least one fixed mold IO module 8, and the fixed mold IO module 8 is coupled to a number of external components 9. The external components 9 include but are not limited to a number of sensors installed in the fixed mold plate area, hydraulic valves and various button indicator lights in the button box (not shown).

[0030] A dynamic mold connection module 10 is provided in the dynamic mold substation box 3. The dynamic mold connection module 10 is coupled to at least one dynamic mold IO module 11. The dynamic mold IO module 11 is coupled to a number of external components 12. The external components 12 include but are not limited to a number of sensors and hydraulic valves installed in the dynamic mold plate area.

[0031] In this embodiment, the main control board 4 , the fixed mold connection module 7 and the movable mold connection module 10 are sequentially coupled via the signal cables 13 to achieve signal transmission among the three.

[0032] The distributed IO control system also includes an injection substation box 14, which is located in the injection seat area of ​​the injection molding machine. An injection connection module 15 is located within the injection substation box 14 and is coupled to the movable mold connection module 10 via a signal cable 13. The injection connection module 15 is coupled to at least one injection IO module 16, which is coupled to several external components 17, including but not limited to several sensors and hydraulic valves installed in the injection seat area.

[0033] In order to monitor the temperature of the injection base barrel, the injection connection module 15 is further coupled to a temperature module 18 , and the temperature module 18 is coupled to a temperature measurement module 19 provided on the injection base barrel (not shown). The temperature measurement module 19 is preferably a thermocouple.

[0034] To simplify the power supply of the distributed IO control system, a power supply 20 is provided within the main control box 1. Power supply 20 is preferably a 24V switching power supply. Power supply 20 is electrically connected to the main control board 4, the fixed mold connection module 7, the movable mold connection module 10, and the injection connection module 15 to respectively supply power to the main control board 4, the fixed mold connection module 7, the movable mold connection module 10, and the injection connection module 15.

[0035] In order to improve the signal transmission efficiency and stability of the signal cable 13 , the signal cable 13 is an EtherCat bus.

[0036] By adopting a distributed IO design, this utility model can expand the IO modules on the original controller to various areas of the injection molding machine, thereby reducing the number of external components for each IO module. This can not only simplify the layout of the power distribution cabinet, but also improve heat dissipation performance, while increasing the convenience of early installation and debugging and later modification and maintenance.

[0037] Furthermore, with a distributed IO design, IO module expansion can be achieved with just one signal cable 13 and one power cable. This allows external components in each area to be directly connected to the corresponding expansion IO module via a short cable, effectively reducing the length of the signal cable 13 and minimizing cable interference.

[0038] Because the external components in each area are directly connected to the corresponding expansion IO module via short cables, when assembling the injection molding machine, only the signal cable 13 and the power cable need to be connected. Compared with centralized IO control systems, this can significantly reduce the use of terminal blocks and connectors, reducing material and labor costs, further improving signal transmission stability, and further reducing the costs of early debugging and subsequent modification and maintenance.
