Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial automation control and monitoring technology, and in particular to an intelligent control and monitoring device for injection molds. Background Technology
[0002] In the injection molding process, due to the complex dynamic interactions between melt flow, pressure transmission, and temperature changes, the stability of key parameters such as temperature distribution of the injection mold, clamping force, mold opening and closing rate, cavity filling pressure, and holding time directly determines the molding quality of the plastic parts. This not only affects the dimensional accuracy, surface finish, and mechanical properties of the product, but also relates to the mold's lifespan and production efficiency. Abnormal fluctuations in these parameters can lead to defects such as shrinkage marks, flash, and warping, increasing the scrap rate; or even serious equipment failures such as mold cavity wear and ejector pin breakage, causing production interruptions and incurring high repair costs. Therefore, real-time monitoring and precise control of relevant injection mold parameters are crucial for ensuring production continuity, improving product qualification rates, and reducing overall production costs, and their importance permeates the entire injection molding process.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0029] like Figures 1-6As shown, this utility model embodiment provides an intelligent control and monitoring device for injection molds, including a control box 11. A door 13 is hinged to the bottom of the front surface of the control box 11 via a pin 12. Connecting blocks 14 are welded to the upper parts of both sides of the door 13. Through holes 15 are opened on the rear side of one side of each of the two connecting blocks 14. Mounting cylinders 16 are fixedly connected to the inner walls of both through holes 15. Limiting rings 17 are slidably connected to the inner walls of both mounting cylinders 16. The inner walls of both limiting rings 17 are fixedly connected to... A plug rod 18 is connected, with both ends of the plug rod 18 passing through the center of the inner side wall of the mounting cylinder 16. Socket holes 19 are provided on the upper part of both sides of the control box 11. The outer side walls of the two plug rods 18 that are close to each other are slidably connected to the inner side walls of the two socket holes 19. Strip lights 20 are installed on the front part of both sides of the inner side wall of the control box 11. A lighting control component 2 is fixedly connected to the center of the front part of the inner top wall of the control box 11. The working state of the strip lights 20 can be easily controlled through the lighting control component 2.
[0030] In one embodiment, specifically: the lighting control assembly 2 includes a housing 21, a push spring 22, an insulating block 23, a push rod 24, and a contact ring 25;
[0031] The top of housing 21 is fixedly connected to the center of the front part of the inner top wall of control box 11. A push spring 22 is fixedly connected to the inner rear wall of housing 21. An insulating block 23 is fixedly connected to the front surface of push spring 22. The outer side wall of insulating block 23 is slidably connected to the inner side wall of housing 21. A push rod 24 is fixedly connected to the center of the front surface of insulating block 23. The front surface of push rod 24 penetrates the center of the inner front wall of housing 21. The front surface of push rod 24 is attached to the center of the top of the rear surface of box door 13. A contact ring 25 is fixedly connected to the outer side of the front surface of insulating block 23 and the outer side of the inner front wall of housing 21. When box door 13 is opened, the push spring 22 pushes the insulating block 23 and push rod 24 to move. The two contact rings 25 make contact and make electrical connection, thereby turning on the strip light 20.
[0032] In a further preferred embodiment, a return spring 26 is fitted on the outer side of each of the two insertion rods 18 away from each other. The two return springs 26 are respectively attached to the outer side of each of the two limiting rings 17 away from each other, and the two return springs 26 are respectively attached to the inner side of each of the two mounting cylinders 16 away from each other. A pull button 27 is fixedly connected to the outer side of each of the two insertion rods 18 away from each other. The return spring 26 facilitates the movement of the limiting ring 17, thereby driving the insertion rod 18 to be inserted into the insertion hole 19 to limit and fix the box door 13. The pull button 27 facilitates the pulling of the insertion rod 18.
[0033] In one embodiment, specifically: a main control board 28 is installed inside the control box 11, and a control module 29, a data acquisition module 30, a storage module 31, a power supply module 32, a clock module 33 and a communication module 34 are provided on the front surface of the main control board 28;
[0034] Among them, the control module 29 is the core processing unit of the device. It is responsible for analyzing the real-time data transmitted by the data acquisition module 30, comparing it with the parameter thresholds preset by the touch screen 36, and judging whether the working status of the injection mold is normal. When the data is abnormal, it can drive the audible and visual alarm 43 to issue a warning, and send adjustment commands (such as adjusting the heating power, clamping force, etc.) to the external actuator through the control port 42 of the control connection panel 40. At the same time, it coordinates the work of each module to achieve precise control of the injection mold.
[0035] The data acquisition module 30 connects to sensors such as temperature, pressure, and displacement on the injection mold through the sensor connection port 41 of the sensor connection panel 39. It receives analog signals (such as temperature electrical signals and pressure strain signals) transmitted by the sensors, converts them into digital signals, and transmits them synchronously to the control module 29 for analysis. At the same time, it sends them to the storage module 31 for recording.
[0036] The storage module 31 is used to store various types of data, including parameter thresholds set through the touch screen 36, real-time monitoring data and historical data transmitted by the data acquisition module 30, and all stored data are timestamps provided by the clock module 33, which facilitates subsequent production process traceability, parameter optimization and fault analysis.
[0037] The power module 32 supplies power to the entire device. After receiving external power, it converts it into voltage and current suitable for the main control board 28 and various modules (control module 29, data acquisition module 30, etc.), touch screen 36, sound and light alarm 43, etc., to ensure the stable operation of each component.
[0038] The clock module 33 is responsible for providing accurate real-time time and adding timestamps to the data recorded by the storage module 31 to ensure that all monitoring data, abnormal events and other information are accurately associated with time, providing a benchmark for time dimension analysis of the production process;
[0039] The communication module 34 is a data interaction bridge between the device and external devices (such as host computers, cloud platforms, remote monitoring terminals, etc.). It can upload real-time monitoring data and alarm information processed by the control module 29 to the external platform, and at the same time receive parameter adjustment instructions sent from the outside and transmit them to the control module 29 to realize remote monitoring and collaborative control.
[0040] In one embodiment, specifically: an upper mounting groove 35 is provided on the upper part of the front surface of the door 13, and a touch screen 36 is fixedly connected to the inner side wall of the upper mounting groove 35; a lower mounting groove 37 is provided on the lower part of the front surface of the door 13, and an emergency control panel 38 is fixedly connected to the inner side wall of the lower mounting groove 37; the touch screen 36 facilitates the input of key parameter thresholds of the injection mold and the real-time display of the working status of the injection mold; the emergency stop button on the emergency control panel 38 facilitates the forced cut-off of the injection molding machine's power source and the cessation of production to protect the equipment in emergency situations.
[0041] In one embodiment, specifically: a sensor connection panel 39 and a control connection panel 40 are respectively provided on both sides of the upper surface of the control box 11. The upper surface of the sensor connection panel 39 is provided with multiple sensor connection ports 41, and the upper surface of the control connection panel 40 is provided with multiple control ports 42. The multiple sensor connection ports 41 on the sensor connection panel 39 facilitate connection with various sensors installed on the injection mold; the control ports 42 on the control connection panel 40 facilitate connection with the PLC or actuator of the injection molding machine.
[0042] In one embodiment, specifically: an audible and visual alarm 43 is installed on the front surface of the door 13 near the upper center of the upper mounting groove 35; the audible and visual alarm 43 facilitates the emission of audible and visual signals to alert on-site personnel.
[0043] In one embodiment, specifically: heat dissipation slots 44 are provided in the middle of both sides of the control box 11, and dust filters 45 are provided on the inner side walls of the heat dissipation slots 44; through the continuous ventilation of the heat dissipation slots 44 on both sides of the control box 11 during device operation, and in conjunction with the dust filters 45 on the inner side, the operating temperature of the main control board 28 and other modules can be reduced, and dust can be prevented from entering and affecting the stability of the circuit.
[0044] In operation, the following steps are taken: First, the operator closes the door 13 around the pivot pin 12. At this time, the insert rods 18 on both sides of the door 13, under the elastic force of the return spring 26 (the return spring 26 pushes the limit ring 17, causing the insert rods 18 to move towards the control box 11), insert their inner ends into the sockets 19 on both sides of the control box 11, locking the door 13 and ensuring the device operates in a closed manner. After connecting the external power supply, the power module 32 starts, supplying power to the main control board 28 and various modules (control module 29, data acquisition module 30, storage module 31, clock module 33, communication module 34, etc.), touch screen 36, and audible and visual alarm 43 inside the control box 11. The clock module 33 starts synchronizing the time, providing timestamps for subsequent data acquisition and recording. The operator inputs key parameter thresholds of the injection mold (such as upper temperature limit, pressure range, holding time, etc.) through the touch screen 36 on the door 13, and the parameters are automatically stored. The storage module 31 completes the monitoring benchmark setting; the sensor connection panel 39 on the upper surface of the control box 11 connects to various sensors (such as temperature sensors, pressure sensors, displacement sensors, etc.) installed on the injection mold through the sensor connection socket 41; the data acquisition module 30 receives analog signals (such as temperature electrical signals, pressure strain signals) transmitted by the sensors in real time, converts them into digital signals, and transmits them synchronously to the control module 29 and the storage module 31; the control module 29 analyzes the real-time acquired data and compares it with the parameter thresholds preset by the touch screen 36; if the data is normal, the touch screen 36 displays parameters such as mold temperature, pressure, and mold opening and closing rate in real time, while the communication module 34 (such as Ethernet, 4G module) uploads the data to the host computer or cloud platform to realize remote monitoring; the storage module 31 continuously records historical data with timestamps from the clock module 33, which is convenient for subsequent production traceability and parameter optimization;
[0045] When the control module 29 detects that the data exceeds the preset threshold (such as excessively high temperature or abnormal cavity pressure), it immediately triggers a dual response:
[0046] Local alarm: The audible and visual alarm 43 on the drive box door 13 of the control module 29 emits an audible and visual signal to alert on-site personnel;
[0047] Automatic control: The control module 29 sends control signals (such as adjusting heating power and adjusting clamping force) to the PLC or actuator of the injection molding machine through the control port 42 on the control connection panel 40 to achieve real-time parameter correction and avoid defects in the plastic parts;
[0048] In case of an emergency (such as mold jamming), on-site personnel can press the emergency stop button through the emergency control panel 38 at the bottom of the box door 13. The signal is directly transmitted to the control module 29 to forcibly cut off the power source of the injection molding machine and stop production to protect the equipment.
[0049] When internal components (such as the main control board 28 and wiring terminals) need to be inspected, the operator pulls the pull buttons 27 on both sides outward, causing the plug rod 18 to compress the reset spring 26 (the limit ring 17 slides along the inner wall of the mounting cylinder 16), so that the inner end of the plug rod 18 disengages from the plug hole 19, and the box door 13 can be opened downward around the pin shaft 12; after the box door 13 is opened, the push rod 24 in the lighting control assembly 2 is no longer squeezed by the box door 13, and the push spring 22 releases its elastic force to push the insulating block 23 forward along the inner wall of the housing 21, so that the contact ring 25 on the front surface of the insulating block 23 contacts the housing 21. When the contact ring 25 on the inner front wall of the control box 11 contacts, the power supply of the strip lighting 20 is turned on, providing illumination for the inside of the control box 11, making it easy for staff to clearly observe the status of the main control board 28 and each module. After the staff completes the maintenance (such as replacing the faulty module or sorting out the wiring), they close the box door 13, and the push rod 24 is pushed back into the housing 21 by the box door 13. The insulating block 23 compresses the push spring 22, the contact ring 25 separates, and the strip lighting 20 automatically turns off. At the same time, the insertion rod 18 is reinserted into the insertion hole 19 under the action of the reset spring 26, locking the box door 13, and the device resumes operation.
[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
