Description

Technical Field

[0001] This invention relates to the field of plastic molding equipment technology, and in particular to an injection mold for easy demolding of plastic products. Background Technology

[0002] In injection molding of plastic products, the demolding process is a critical step affecting product quality and production efficiency. Traditional injection molds have the following technical defects: First, demolding parameters rely on manual experience for setting, and the differences in characteristics of different plastic materials (such as PP and ABS) lead to poor parameter adaptability, easily resulting in product deformation or demolding jamming; second, there is a lack of real-time monitoring mechanisms, making it impossible to intervene in time when abnormal demolding force or cavity temperature fluctuations occur, resulting in a high product scrap rate; third, production task management is disconnected from the demolding process, making it difficult to achieve accurate tracking of order progress and traceability of anomalies.

[0003] In existing technologies, patent CN208261818U discloses a die-casting mold for monitoring equipment accessories, which improves the demolding effect by setting demolding vents and demolding patterns, but does not involve intelligent parameter control and digital management of the production process; patent CN223211820U proposes a slider-type submerged injection structure, which focuses on runner optimization but lacks closed-loop control of key parameters such as demolding force and temperature. Therefore, it is necessary to provide an injection mold for plastic products that facilitates demolding to solve the above-mentioned technical problems. Summary of the Invention

The production task management unit is used to break down plastic product production orders, track demolding production progress, and record events during the production process.

[0007] As a preferred embodiment, the core control layer of the demolding monitoring and control system also includes a parameter template unit, which has built-in material and demolding parameter association templates corresponding to different plastic materials. Users can call the corresponding template based on the material used in the currently produced plastic product and send it to the execution component of the mechanical mold body with one click.

[0008] In a preferred embodiment, when the abnormal early warning unit of the demolding monitoring and control system triggers an early warning, it simultaneously performs the following: displays abnormal information and troubleshooting suggestions through the visualization application layer, sends a pause command to the demolding mechanism and injection mechanism of the mechanical mold body, records the parameter data and processing process when the abnormality occurs, and stores them in the data storage layer.

[0009] In a preferred embodiment, the support assembly includes a lower sealing plate, a mold foot fixed to the upper end of the lower sealing plate, a male template fixed to the upper end of the mold foot, and an upper sealing plate located above and adapted to the male template, with a female template fixed to the lower end of the upper sealing plate; the guide and positioning assembly includes a guide post fixed to the lower end of the female template, a guide member movably installed on the male template and adapted to the guide post, and a second positioning block on the female template and a first positioning block on the male template respectively.

[0010] In a preferred embodiment, the mold core assembly includes a female mold core fixed to the lower end of the female mold plate and a male mold core fixed to the upper end of the male mold plate and adapted to the female mold core. The female mold core and the male mold core cooperate to form a cavity for molding the plastic product.

[0014] Compared with related technologies, the injection mold for easy demolding of plastic products provided by the present invention has the following beneficial effects: 1. This solution addresses the problems of traditional molds relying on manual setting of demolding parameters and poor adaptability. The core control layer parameter template unit has built-in demolding parameter templates for different plastic materials, which can be directly called; the real-time parameter control unit dynamically adjusts the state of the demolding mechanism and injection mechanism based on sensor data to ensure that the pushing force, cavity environment, etc. are adapted to the product characteristics, avoiding product deformation and jamming caused by improper parameters, eliminating manual intervention, and ensuring molding quality and production continuity.

[0015] 2. The abnormality early warning unit monitors parameters and component status in real time. When an abnormality occurs, a pop-up window will simultaneously provide troubleshooting suggestions, suspend relevant mechanisms, and record data. This enables the abnormality to be proactively controlled instead of passively responding to it, avoiding the continuous occurrence of abnormalities that could lead to batch scrapping of products or damage to molds, reducing ineffective production, and lowering overall losses.

[0016] In summary, this solution effectively addresses the technical pain points of traditional molds, such as poor adaptability of manually set demolding parameters and passive response to anomalies, through the collaboration of the core control layer and the anomaly early warning unit of the demolding monitoring and control system. The core control layer directly calls demolding parameter templates for different plastic materials through the parameter template unit, and combines the analysis of sensor data and dynamic optimization of the mechanism status by the real-time parameter adjustment unit to ensure the molding quality and production continuity of plastic products. The anomaly early warning unit avoids batch scrapping of products and mold damage through real-time monitoring and proactive prevention of anomalies, ultimately achieving the technical effects of improved production quality and efficiency and reduced overall losses.

After analyzing the parameters, the demolding monitoring and control system sends control commands to the demolding mechanism and injection mechanism of the mechanical mold body to realize automated monitoring and precise control of the demolding process.

[0023] Specifically, the core control layer of the demolding monitoring and control system includes: The real-time parameter control unit receives data collected by the status detection sensor group, compares it with the preset demolding parameter range, and generates control commands for adjusting the operating status of the demolding mechanism drive components and the injection status of the injection mechanism, specifically: The system receives data collected by the status detection sensor group, including the actual demolding force F output by the demolding mechanism drive, the actual displacement S of the ejector pin 14, the actual cavity temperature T, and the actual injection flow rate Q of the injection mechanism.

The formula is Preset displacement allowable deviation ,like When this happens, a drive component stroke adjustment command is generated, along with the corresponding adjustment amount for the drive component. ,satisfy , used for reverse compensation of displacement deviation; The deviation between the actual cavity temperature and the median of the preset range is calculated using the following formula: Preset temperature tolerance ,like When the time is right, a dispensing flow rate adjustment command is generated, and the adjustment amount of the corresponding drive component is calculated. The adjustment amount satisfies the following conditions: ;in The injection flow rate-temperature adjustment coefficient is preset based on the characteristics of the plastic material. By adjusting the injection flow rate, it adapts to the cavity temperature requirements and ensures the demolding effect. It should be noted that, These are all preset parameters based on the mold model and the characteristics of the plastic product, and can be modified through the visual application layer.

[0024] The anomaly warning unit monitors abnormal states during the demolding process and triggers an alarm when key parameters exceed preset ranges or component movement is abnormal. Specifically: like The system is determined to have abnormal demolding force, triggering an abnormal force warning command. like When the displacement of the jacking component is abnormal, a displacement abnormality warning command is triggered. The formula for calculating the deviation rate between the actual temperature and the preset range is: ,like The system is determined to be in an abnormal cavity temperature, triggering a temperature abnormality warning command. The actual reset time is directly compared with the preset maximum allowable time. The formula is: ,like The system was determined to be an abnormal reset timeout of the pusher component, triggering a reset timeout abnormality warning command. The production task management unit is used to break down plastic product production orders, track demolding progress, and record events during the production process. It supports manual entry or import of plastic product production order information containing order number, product model, total production quantity, and plastic material type from ERP system, and completes the structured decomposition of orders by time and mold dimensions and preloads the corresponding demolding parameter templates; Data on effective demolding counts and product molding counts are obtained from the status detection sensor group and injection molding machine. The progress is calculated by calculating the actual completion rate = (cumulative effective demolding counts - cumulative scrapped quantity) / total number of sub-tasks × 100% and displayed in the visualization application layer. Early warnings are triggered according to the progress deviation. The system categorizes and records normal production events (including successful demolding parameters and task switching information) and abnormal production events (related to abnormal warning unit information and processing procedures). It creates indexes by order number, mold number, and timestamp and stores them in the data storage layer, supporting multi-dimensional filtering and querying as well as Excel report export.

[0025] Specifically, the parameter template unit of the core control layer of the demolding monitoring and control system has built-in templates that associate material with demolding parameters based on the properties of different plastic materials. For different plastic materials such as PP, ABS, and PE, the templates contain key parameters that are adapted to the mechanical mold body's execution components. The rotational speed range of the drive motor 16 in the demolding mechanism and the ejection speed / force range of the ejector pin 14; the heating temperature range of the heating tube in the temperature control assembly and the cooling medium flow range of the cooling channel; and the injection flow range associated with the injection tube sleeve 10 in the injection molding mechanism. Users can select the corresponding template based on the material type used in the current plastic product production at the visualization application layer. After clicking the operation, the template parameters are sent to the execution components of the mechanical mold body through the hardware interface layer. The execution components include the drive motor 16, heating pipe, cooling channel, and the glue injection system associated with the glue injection tube sleeve 10. The template parameters can be fine-tuned by the administrator at the core control layer based on the actual demolding effect of the mold, such as demolding success rate and product defect rate, to adapt to the differences in the characteristics of different batches of plastic materials or the performance changes of the mold after long-term use.

[0026] Specifically, when the abnormal early warning unit of the demolding monitoring and control system triggers an early warning, it simultaneously executes the following: The visualization application layer displays abnormal information and troubleshooting suggestions, sends pause commands to the demolding mechanism and injection mechanism of the mechanical mold body, records parameter data and processing procedures when abnormalities occur, and stores them in the data storage layer.

[0027] Specifically, the support components include a lower sealing plate 1, a mold foot 2 fixed to the upper end of the lower sealing plate 1, a male template 3 fixed to the upper end of the mold foot 2, and an upper sealing plate 6 located above the male template 3 and adapted to the male template 3. A female template 7 is fixed to the lower end of the upper sealing plate 6. The guide and positioning components include a guide post 12 fixed to the lower end of the female template 7, a guide cylinder 5 movably installed on the male template 3 and adapted to the guide post 12, and a second positioning block 8 respectively provided on the female template 7 and a first positioning block 4 on the male template 3, which are adapted to each other.

[0028] Specifically, the mold core assembly includes a female mold core 13 fixed to the lower end of the female mold plate 7, and a male mold core 11 fixed to the upper end of the male mold plate 3 and adapted to the female mold core 13. The female mold core 13 and the male mold core 11 cooperate to form a cavity for molding the plastic product. The injection assembly includes an injection hole that passes through the female mold core 13, the female mold plate 7 and the upper sealing plate 6, a positioning ring 9 fixed to the upper end of the upper sealing plate 6 and used to position the injection nozzle, and an injection tube sleeve 10 embedded between the female mold plate 7 and the upper sealing plate 6 and communicating with the injection hole. The injection tube sleeve 10 is used to achieve a sealed connection between the injection nozzle and the injection hole.

[0029] Specifically, the driving component of the demolding mechanism is a drive motor 16 fixed to the mechanical frame support assembly. The transmission assembly includes an eccentric disk fixed to the output end of the drive motor 16, and a hinge rod 15 with one end hinged to the eccentric disk and the other end hinged to the pusher. The pusher is a push rod 14 that vertically moves through the male mold core 11 and the male mold plate 3. When the drive motor 16 is running, it drives the eccentric disk to rotate. The rotational motion is converted into the linear motion of the ejector rod 14 through the hinge rod 15, which in turn pushes the plastic product between the female mold core 13 and the male mold core 11 to separate.

[0030] Specifically, the key parameters collected by the state detection sensor group include: The sensor group is used to monitor the displacement parameters of the ejector pin 14, the force parameters of the output power of the drive motor 16, and the temperature parameters of the cavity temperature between the female mold core 13 and the male mold core 11. The sensor group is respectively arranged on the side wall of the ejector pin 14, the output end of the drive motor 16, and the inner wall of the cavity between the female mold core 13 and the male mold core 11.

[0031] Specifically, the mother template 7 of the mechanical frame is provided with internal threaded holes 17 for lifting rings on both sides for hoisting and handling; The injection tube sleeve 10 of the injection mechanism is coaxially arranged with the positioning ring 9, and the inner diameter of the injection tube sleeve 10 is adapted to the injection nozzle of the injection molding machine; the upper end face of the ejector rod 14 of the demolding mechanism is flush with the bottom surface of the cavity of the male mold core 11 to ensure uniform force when pushing the plastic product.

[0032] This invention achieves precise control over the entire process from injection molding to automated demolding of plastic products through the coordinated operation of the mechanical mold body and the demolding monitoring and control system. The specific working principle is as follows: Pre-production parameter preparation: Users can access the demolding monitoring and control system's visual application layer and, based on the material type of the plastic products being produced (such as PP or ABS), call the material and demolding parameter association template built into the core control layer parameter template unit. The template parameters (including the speed range of the drive motor 16, the ejection force range of the ejector pin 14, the cavity temperature range, and the injection flow rate) are sent to the mechanical mold body's execution components via the hardware interface layer. At the same time, the status detection sensor group (ejector pin 14 sidewall displacement sensor, drive motor 16 output force sensor, and cavity inner wall temperature sensor) completes initialization.

[0033] Mold closing and injection molding: The demolding monitoring and control system issues a mold closing command, and the upper sealing plate 6 drives the female mold plate 7 to move down. The guide post 12 of the female mold plate 7 is inserted into the guide tube 5 of the male mold plate 3. The second positioning block 8 and the first positioning block 4 are engaged to achieve precise mold closing. The injection molding machine's injection nozzle is positioned by the positioning ring 9 and sealed to the injection tube sleeve 10. The molten plastic is injected into the cavity formed by the female mold core 13 and the male mold core 11 through the injection hole. After holding the pressure, it is cooled and solidified.

[0034] Parameter verification and adjustment before demolding: The status detection sensor group collects parameters such as cavity temperature, initial displacement of ejector pin 14, and standby force of drive motor 16, and transmits them to the core control layer through the hardware interface layer. The real-time parameter control unit compares the collected data with the preset range. If there is a deviation (such as abnormal cavity temperature), it generates a command to adjust the temperature control component or the injection flow rate until the demolding conditions are met.

[0035] Automated demolding execution: Once the demolding conditions are met, the demolding monitoring and control system sends a command to the demolding mechanism. The drive motor 16 drives the eccentric disk to rotate, and the rotational motion is converted into the linear motion of the ejector rod 14 through the hinge rod 15, pushing the solidified plastic product out of the cavity. During the process, the sensor group collects the displacement of the ejector rod 14 and the force of the drive motor 16 in real time. The real-time parameter control unit dynamically adjusts the speed of the drive motor 16 to control the ejection force and speed, avoiding product damage.

[0036] Anomaly protection and progress management: The abnormal warning unit monitors parameters in real time (such as demolding force exceeding the range, ejector pin 14 reset timeout). If an abnormality is triggered, the following actions are executed simultaneously: the visualization application layer displays abnormal information and troubleshooting suggestions, sends a pause command to the demolding / injection mechanism, and records abnormal data to the data storage layer; the production task management unit counts the number of effective demoldings, calculates the production progress (actual completion rate = (cumulative number of effective demoldings - cumulative number of scrapped items) / total number of sub-tasks × 100%), and stores the entire process data for traceability.

[0037] Cyclic Reset: After the product is demolded, the drive motor 16 drives the ejector rod 14 to reset, the sensor group verifies the reset status, and the system prepares to receive the next batch of orders. The above process is repeated to achieve continuous production.

[0038] Additional notes: The real-time parameter control unit and the anomaly early warning unit in this solution involve the demolding force deviation rate. 16 speed adjustment range of drive motor Cavity temperature deviation rate All formulas are calculated by taking numerical values ​​after removing dimensions. Dimension removal can be achieved through conventional methods such as standardization, which will not be elaborated here. The formula was obtained by software simulation and fitting of a large amount of demolding data of plastic products (including demolding parameters of different materials and product structures), which can closely approximate the actual demolding scenario. Preset parameters in the formula (such as) (etc.), which shall be set by those skilled in the art in combination with the mold model, plastic material characteristics and product precision requirements.

[0039] Each embodiment of this solution can be implemented by software, hardware, firmware, or any combination thereof. If implemented by software, it can be embodied as a computer program product, containing computer instructions. When the instructions are loaded or executed, they generate corresponding demolding control, abnormal warning, and other processes / functions. The instructions can be transmitted between computer devices (such as injection molding machine control terminals and servers) via wired or wireless means and stored in computer-readable storage media (such as USB flash drives, ROM, RAM, magnetic disks, and optical disks).

[0040] The program numbers do not represent the order of execution; the execution order is determined by the functional logic of the demodulation control. The functional implementation (hardware / software) of each example unit and algorithm step depends on the specific application scenario and design constraints. Professional technicians can choose as needed, without exceeding the scope of this solution.

[0041] Other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
