Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, in particular to a method for efficiently and intelligently producing an injection molding mold frame and controlling the same. Background Art

[0002] Injection molding is a key method for producing plastic products in modern manufacturing. Traditional injection molding processes often rely on operator proficiency and expertise, which not only increases dependence on operators but also easily introduces human error during production, leading to inconsistent product quality. Furthermore, uncontrollable factors in the injection molding cycle, such as the speed at which inserts are placed, further increase uncertainty in the production process, impacting product quality and efficiency. Furthermore, the speed at which inserts are placed is the most uncontrollable factor, contributing to instability in the injection molding cycle. This results in an uncertain length of time the plastic material remains in the constant-temperature barrel, leading to variations in the plastic's molten state during injection molding, resulting in varying product outcomes (e.g., burrs, flash, and incomplete shots).

[0003] With the advancement of industrial automation and intelligent manufacturing, more and more manufacturers are seeking technological solutions to address issues encountered in traditional injection molding processes. The introduction of automated equipment can reduce reliance on human operators, improve the stability and repeatability of the production process, and thus enhance product quality. However, existing automation solutions often focus on a single production step and lack comprehensive optimization of the entire production cycle, which limits further improvements in production efficiency.

[0004] The development of intelligent control technology has revolutionized the injection molding process. By integrating advanced sensors, control systems, and automation modules, precise control of the injection molding process can be achieved, ensuring that each production step is accurately executed according to pre-set procedures. Intelligent control not only improves production efficiency but also effectively reduces defective product rates, enhancing overall product quality. For example, patent publication number CN117183259B discloses a reclaiming system for automatically shifting injection molding molds. The system comprises two horizontal injection molding machines (left and right), corresponding manipulators, front and rear vertical injection molding machine manipulators, a positioning conveyor, and a vertical injection molding machine and discharge conveyor. This system enables fully automated and rapid production of box bodies. As can be seen, intelligent production offers a high level of automation, avoids repetitive labor, and has wide applicability. In the field of injection molding, particularly for insert molding processes, there is currently a lack of intelligent production processes, particularly dual-module intelligent production injection molding devices and control methods. Therefore, there is a need for an efficient dual-module intelligent production injection molding mold base and control method. Summary of the Invention

[0046] A control method for efficiently producing a dual-module intelligent injection molding mold frame includes the following steps:

[0047] Step 1: The mold opening signal is transmitted to the mold frame;

[0048] Step 2: After the mold frame receives the mold opening signal from the injection molding machine, the injection molding machine template opens and the A module is positioned from the first center of the longitudinal track (see Figure 1 A position) to the second center position (see Figure 1 C position);

[0049] Step 3: Module A moves from the second center position on the transverse track 18 to the left position on the mold frame (see Figure 1 B position);

[0050] Step 4: Module B moves synchronously with module A and is positioned on the right side of the mold frame on the horizontal track 18 (see Figure 1 D position) into the second center positioning position of the mold base;

[0051] Step 5: While module A is positioning and ejecting the product on the left side of the mold frame, module B enters the first center positioning position of the mold frame on the longitudinal track. After the injection molding machine receives the signal, the mold plate closes and injection molding begins;

[0052] Step 6: While module B is being injection molded at the first center position of the mold frame, module A is being installed with the insert to be injection molded at the left position of the mold frame.

[0053] Step 7: After the injection molding of module B is completed at the first center position of the mold frame, the injection molding machine template is opened, and module B slides from the first center position to the second center position of the longitudinal track;

[0054] Step 8: Module B moves rightward from the second center position on the transverse track 18 to the right side of the mold frame, and module A moves rightward from the left side of the mold frame to the second center position on the transverse track 18;

[0055] Step 9: While module B is positioning and ejecting the product on the right side of the mold frame, module A enters the first center positioning position of the mold frame on the longitudinal track. After the injection molding machine receives the signal, the mold plate closes and injection molding begins;

[0056] Repeat steps 1 to 9 to achieve dual-module intelligent continuous automated production of injection molded products.

[0057] Modules A and B are dual modules, performing injection molding, product ejection, and insert installation at different locations on the mold base. This allows for alternating operation and improves production efficiency. The mold base receives the mold opening signal from the injection molding machine and controls the movement and operation of modules A and B, enabling intelligent injection molding.

[0058] The control method further includes:

[0059] Optimal injection speed control:

[0060] Monitor the injection pressure P and injection speed v of the injection molding machine in real time, and calculate the optimal injection speed v according to the following formula opt :

[0061]

[0062] Where, P is the injection pressure, the unit is Pascal (Pa); A is the injection area of ​​the mold core, the unit is square meters (m 2 ); η is the dynamic viscosity of the injection molding material, in Pascal·second (Pa·s); v opt The injection speed v is the optimal injection speed in meters per second (m / s). The injection speed v is dynamically adjusted based on the real-time pressure P to ensure the stability of the injection molding process and product quality.

[0063] By dynamically adjusting the injection speed v to match the real-time injection pressure P and the mold core's injection area A, the stability of the injection molding process and the consistency of product quality can be significantly improved. This adaptive control strategy effectively reduces product defects caused by uneven injection speeds, such as burrs, flash, and incomplete shots, while also optimizing injection molding efficiency and shortening production cycles. Furthermore, intelligent dynamic adjustment reduces reliance on manual experience, lowers defective product rates, enhances production automation and adaptability, and provides strong support for technological advancement and industrial upgrading in the injection molding industry.

[0064] Also includes dynamic control of cooldown time:

[0065] During each injection molding process, calculate the cooling time t c , and adjust the cooling time according to the following formula:

[0066]

[0067] Among them, C p is the specific heat capacity of the injection molding material, in joules / (kg·Kelvin) (J / (kg·K)); ρ is the density of the injection molding material, in kilograms / cubic meter (kg / m 3 ); V is the volume of the injection molded product, in cubic meters (m 3 ); h is the comprehensive heat transfer coefficient of the mold cooling system, the unit is watt / (square meter Kelvin) (W / (m 2 ·K)); A is the effective heat transfer area of ​​the mold cooling system, in square meters (m 2 );t c is the cooling time, in seconds (s). Cooling time t c Dynamic adjustment to ensure cooling effect and product quality after injection molding.

[0068] By dynamically adjusting the injection speed υ and cooling time tc , significantly improving the intelligent level of the injection molding process, production efficiency and product quality consistency. Dynamic injection speed control adjusts the optimal injection speed v according to the real-time injection pressure P and mold core injection area A. opt , ensure the best melt flow state, reduce filling defects, improve filling quality, optimize the injection cycle and improve production efficiency. Dynamic cooling time control, by accurately calculating the cooling time t c This ensures efficient and sufficient cooling, preventing product warping, dimensional instability, and internal stress caused by insufficient or excessive cooling, further safeguarding product quality and stability. This intelligent dynamic control strategy reduces reliance on manual experience, lowers defective product rates, enhances production automation and adaptability, and provides strong support for technological advancement and industrial upgrading in the injection molding industry.

[0069] The efficient dual-module intelligent production injection molding mold frame of this embodiment significantly improves production efficiency through the dual-module alternating working mode. Modules A and B alternate during operations such as injection molding, product ejection, and insert installation, effectively reducing equipment idle time. For example, while one module is ejecting the product and installing the insert, the other module has already entered the injection molding stage, achieving multi-step synchronization and making the production process more compact and efficient. In addition, the mold frame is highly automated, reducing reliance on manual labor, lowering labor intensity and labor costs, while also reducing the safety risks and errors caused by manual operation.

[0070] In terms of improving product quality, the mold base ensures consistent production conditions by precisely controlling the movement, positioning, and injection molding parameters of the modules. This effectively reduces defects such as burrs, flash, and incomplete shots, and improves the stability and consistency of product quality. The modular design enhances the mold base's flexibility and adaptability, facilitating rapid mold changes to accommodate the production needs of products of varying specifications. It also enables precise control of production speed and quality through parameter adjustments. The mold base lays the foundation for standardized, automated, and intelligent production, driving technological advancement and industrial upgrading in the injection molding industry. It possesses broad application value and significant innovative significance.

[0072] The mobile seat 21 includes an A mobile seat 21 and a B mobile seat 21. The A mobile seat 21 is set at the bottom of the A module, and the A mobile seat 21 is set at the bottom of the B module. The base 20 can only be assembled with the A mobile seat 21 or the B mobile seat 21 at the same time, and cannot be assembled with the A mobile seat 21 and the B mobile seat 21 at the same time.

[0073] In this embodiment, the first power unit enables the movement of modules A and B along the longitudinal track. The first motor 14 drives the connecting rod, which in turn drives the base 20 and movable seat 21 to move smoothly along the track.

By disposing the first motor 14 on a base, mounting the base on the platform 2, providing a longitudinal track on the base, and providing a matching guide groove on the base 20, precise guidance and stable support for the longitudinal movement of modules A and B are achieved. The longitudinal track provides a clear path for the movement of the module, ensuring its straightness and stability during longitudinal movement, avoiding production failures caused by movement deviations, and thus improving production reliability and product quality consistency. At the same time, the setting of the base provides a stable installation foundation for the first motor 14 and the longitudinal track, enhancing the structural stability of the entire power unit, enabling it to withstand the forces and loads generated during module movement, and extending the service life of the equipment.

[0076] In a preferred embodiment, the base is provided with a side plate 16, which includes a first side plate 16 and a second side plate 16. The side plate 16 is provided with an L-shaped groove, which includes a longitudinal groove and a transverse groove; the side edge of the movable seat 21 cooperates with the L-shaped groove (see Figure 3 and Figure 5).

The side panel 16 is provided with an L-shaped groove, which includes a longitudinal groove and a transverse groove; the side of the movable seat 21 cooperates with the L-shaped groove. Accurate guidance and limitation of the movable seat 21 during the longitudinal and transverse movement are achieved. The longitudinal groove and the transverse groove of the L-shaped groove correspond to the longitudinal and transverse movement paths of the module respectively, ensuring the accurate movement of the movable seat 21, avoiding offset and shaking, and thus improving the stability and accuracy of the module movement. At the same time, the provision of the side panel 16 enhances the overall structural strength of the base, provides reliable support for the stable operation of the movable seat 21, and further enhances the reliability and durability of the equipment. This design not only optimizes the motion control of the module, but also simplifies the overall structure, reduces the complexity and maintenance cost of the equipment, and improves the production efficiency and operational stability of the equipment.

[0078] Modules A and B are driven by a synchronization mechanism, which includes a linkage block 27, a connector 28, a first slider 24, a second slider, and a transmission shaft 26. Transmission shaft 26 is driven to rotate by a power device (e.g., a second motor). Transmission shaft 26 is threadedly engaged with linkage block 27, and rotation of the transmission shaft drives linkage block 27. This embodiment ensures a high degree of synchronization between modules A and B during movement. The linkage block 27 on transmission shaft 26 is movable along the transmission shaft 26 and fixed to connector 28, ensuring uniform and stable power transmission to both modules.

When the A moving seat 21 moves longitudinally to the second center positioning position, the A moving seat 21 automatically enters the two limit columns, and then the two limit columns can drive the A moving seat 21 to slide out horizontally from the slide groove of the base 20, so that the A moving seat 21 is separated from the base 20 and moved to the left side of the mold frame for positioning; the second auxiliary block 23 is provided with two limit columns, and the two limit columns are used to limit the B moving seat 21.

[0084] In a preferred embodiment, the A module and the B module have the same structure and are collectively referred to as a module body. The module body (A module and B module) includes a vertical plate 31, an ejector base plate 29, an ejector panel 303, a spring 36, a guide column and a mold core (including an A mold core 8 and a B mold core 9). The mold core is arranged on the vertical plate 31. The vertical plate 31 includes a first vertical plate 31 and a second vertical plate 31. The ejector base plate 29 is arranged between the first vertical plate 31 and the second vertical plate 31. The ejector panel 303 is arranged on the ejector base plate 29. An ejection device (ejector) is arranged on the ejector base plate 29 and the ejector panel 303. A spring 36 is arranged on the ejector panel 303.
