Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and in particular to a fully automatic mold-changing injection molding production system with dual injection molding machines linked together. Background Technology

[0002] With the continuous acceleration of product iteration in downstream industries such as new energy vehicles, large home appliances, and logistics plastic pallets, the market production model has shifted from the traditional rigid production model of large-volume, few-variety, and long-delivery-time production to a flexible production model of multiple varieties, small-volume, and short-delivery-time production. Consequently, the mold change frequency of ultra-large injection molding machines with capacities of 2600 tons and 2800 tons, which produce large plastic parts, has increased significantly, with the average daily mold change frequency surging from 1.2 times under the traditional production model to 4.7 times.

[0003] Currently, 2600-ton and 2800-ton ultra-large injection molding machines in the industry are generally deployed as stand-alone units, with each machine built and used independently. There is no collaborative mechanism between the machines, nor is an integrated fully automatic mold-changing system configured. Mold-changing operations are still mainly done manually or through semi-automated, decentralized processes. However, these existing traditional mold-changing operations require 2 to 3 operators to complete, and a single mold-changing operation can take 1 to 4 hours. Even with some semi-automated auxiliary equipment, the mold-changing time still takes 20 to 30 minutes. Under high-frequency mold-changing conditions, a large amount of effective production time is consumed by mold-changing operations, creating a bottleneck in production capacity. Furthermore, the various interfaces required for mold operation, such as water, electricity, hydraulics, and gas, rely entirely on operators to manually plug and unplug them one by one. Due to the large number of interface types, their chaotic arrangement, and the inconsistent interface configurations of each mold, misconnections and omissions are very likely to occur. This can lead to poor product molding at best, and equipment failure or even safety accidents at worst. Troubleshooting and rework further prolong downtime. Summary of the Invention

[0004] This invention provides a fully automatic injection molding production system with dual injection molding machines linked together. It can solve the problems in the prior art where a large amount of effective production time is occupied by mold changing operations under high-frequency mold changing conditions, forming a production capacity bottleneck. In addition, the system has many types of interfaces, messy layout, and different configurations of interfaces for each mold, which makes it easy to have incorrect or missing connections.

[0005] A fully automated injection molding production system with dual injection molding machines includes a mounting base. A first injection molding machine and a second injection molding machine are respectively installed on both sides of the mounting base. Molds are installed inside the first and second injection molding machines. A transfer platform, a machine control box, and a docking mechanism are installed on the mounting base. A connecting plate is installed on the mold. The docking mechanism includes an automatic docking component on the moving mold side and an automatic docking component on the fixed mold side. Both the automatic docking component on the moving mold side and the automatic docking component on the fixed mold side include an equipment-side base plate and a mold-side base plate. A connector assembly is installed on the equipment-side base plate and the mold-side base plate. The equipment-side base plate is connected to the first and second injection molding machines through a fixing component, and the mold-side base plate is connected to the connecting plate.

[0006] The present invention provides a fully automatic injection molding production system with dual injection molding machines linked together, which, compared with the prior art, has the following beneficial effects, but is not limited to: This fully automated mold-changing injection molding production system, which links two injection molding machines, is installed on opposite sides of a mounting base. A transfer platform on the base allows both machines to share a single mold-changing resource. While one machine is changing molds, the other can continue production, effectively reducing downtime during high-frequency mold-changing operations and breaking capacity bottlenecks. Furthermore, the automatic docking components on both the moving and fixed mold sides of the docking mechanism employ a standardized layered structure of equipment-side and mold-side base plates. The equipment-side base plate has connectors fixed to the injection molding machine, while the mold-side base plate connects to the mold via a connecting plate. This allows all water, electricity, hydraulic, and gas interfaces to be prefabricated on the equipment side and selected on the mold side as needed. During mold changing, the mold-side base plate and equipment-side base plate are simply joined together to complete the synchronous docking of all interfaces, replacing manual insertion and removal. This avoids misconnections and omissions, improving production stability and mold-changing efficiency during high-frequency mold-changing operations.

[0007] Furthermore, the connector assembly includes a cooling water connector, a hot runner heating and temperature sensing control connector, a neutron core extraction control circuit connector, a needle valve control circuit connector, a hydraulic pipeline connector, and a pneumatic pipeline connector.

[0008] Furthermore, a dedicated cable tray is provided on one side of the automatic docking component on the moving mold side. The dedicated cable tray is connected to the equipment side base plate through connectors, and all cables and pipelines are neatly arranged on the dedicated cable tray.

[0009] Furthermore, the transfer station includes a bidirectional conveyor belt and a mold buffer station. The bidirectional conveyor belt is located between the first injection molding machine and the second injection molding machine, and the mold buffer station is used to store molds to be switched.

[0010] Furthermore, the mold is provided with a locking mechanism, which includes a mounting slide plate connected to the mold. Each of the four corners of the mounting slide plate is connected to a locking cylinder, and the driving end of the locking cylinder is connected to a locking rod. The first and second injection molding machines are provided with locking holes adapted to the locking rod.

[0011] Furthermore, the overall control box is electrically connected to the transfer station, docking mechanism, and locking mechanism.

[0012] Furthermore, a floating compensation mechanism is provided between the equipment-side substrate and the mold-side substrate. The floating compensation mechanism includes an elastic floating element and a circumferential limiting structure arranged along the docking direction.

[0013] Furthermore, the elastic floating element includes a buffer spring and a compression spring. The buffer spring is mounted on the equipment-side substrate, and the compression spring is mounted on the mold-side substrate. One end of the buffer spring is in contact with one end of the compression spring.

[0014] Furthermore, the circumferential limiting structure includes multiple limiting cylinders and multiple limiting slide rods. The multiple limiting cylinders are mounted on the equipment side base plate, and the multiple limiting slide rods are mounted on the mold side base plate. The limiting slide rods are adapted to the limiting cylinders.

[0015] Furthermore, the first injection molding machine is a 2600-ton injection molding machine, and the second injection molding machine is a 2800-ton injection molding machine. Attached Figure Description

[0023] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a fully automatic injection molding production system with dual injection molding machines linked together, including a mounting base 1. A first injection molding machine 2 and a second injection molding machine 3 are respectively arranged on both sides of the mounting base 1. A mold 4 is respectively arranged inside the first injection molding machine 2 and the second injection molding machine 3. A transfer platform 5, a whole machine coordination control box 6 and a docking mechanism 7 are arranged on the mounting base 1. A connecting plate 8 is arranged on the mold 4. The docking mechanism 7 includes an automatic docking component 71 on the moving mold side and an automatic docking component 72 on the fixed mold side. Both the automatic docking component 71 on the moving mold side and the automatic docking component 72 on the fixed mold side include an equipment side base plate 711 and a mold side base plate 712. A connector component 73 is arranged on the equipment side base plate 711 and the mold side base plate 712. The equipment side base plate 711 is connected to the first injection molding machine 2 and the second injection molding machine 3 through a fixing member 713. The mold side base plate 712 is connected to the connecting plate 8.

[0024] In this embodiment, a first injection molding machine 2 and a second injection molding machine 3 are respectively installed on both sides of the mounting base 1. Together with the transfer platform 5 installed on the mounting base 1, the two injection molding machines share a single set of mold-changing resources. When one injection molding machine is in the process of changing molds, the other can maintain production, effectively reducing equipment downtime under high-frequency mold-changing conditions and thus breaking through production capacity bottlenecks. Simultaneously, the automatic docking component 71 on the moving mold side and the automatic docking component 72 on the fixed mold side of the docking mechanism 7 both adopt a standardized layered structure of the equipment-side substrate 711 and the mold-side substrate 712. The equipment-side base plate 711 is provided with a connector assembly 73 and fixed to the injection molding machine by a fastener 713. The mold-side base plate 712 is connected to the mold 4 through a connecting plate 8, so that all media interfaces such as water, electricity, liquid, and gas are uniformly prefabricated on the equipment side and selected as needed on the mold side. When changing molds, the mold-side base plate 712 and the equipment-side base plate 711 only need to be attached at one time to complete the synchronous docking of all interfaces, replacing the manual insertion and unplugging operation one by one, avoiding the problems of incorrect connection and missing connection, and improving the production stability and mold changing efficiency under high frequency mold changing conditions.

[0025] Among them, the first injection molding machine 2 is a 2600-ton injection molding machine, and the second injection molding machine 3 is a 2800-ton injection molding machine; the first injection molding machine 2 and the second injection molding machine 3 adopt an alternating operation mode. When one injection molding machine is in the mold changing operation state, the other injection molding machine maintains the normal production state, so as to achieve the time overlap between the production task and the mold changing task.

[0026] like Figure 2 and Figure 4 As shown, the connector assembly 73 includes a cooling water connector 731, a hot runner heating and temperature sensing control connector 732, a neutron core extraction control circuit connector 733, a needle valve control circuit connector 734, a hydraulic pipeline connector 735, and a pneumatic pipeline connector 736.

[0027] In this embodiment, the connector assembly 73 integrates a cooling water connector 731, a hot runner heating and temperature sensing control connector 732, a neutron core-pulling control circuit connector 733, a needle valve control circuit connector 734, a hydraulic pipeline connector 735, and a pneumatic pipeline connector 736. This consolidates all the media interfaces required for mold operation into a single standardized module, covering all functional requirements for mold cooling, hot runner temperature control, core-pulling action control, needle valve opening and closing control, hydraulic drive, and pneumatic assistance. One connector assembly can adapt to various complex molds without requiring customization for different molds. The separate interface configuration for the mold significantly improves the system's versatility and compatibility. Furthermore, with all connectors integrated into connector assembly 73, all media can be simultaneously connected by simply aligning connector assembly 73 during mold changes. This eliminates the traditional method of manually plugging and unplugging various pipelines, fundamentally preventing misconnections and omissions caused by a wide variety of interfaces and their chaotic arrangement. It also eliminates the chain reaction of losses caused by incorrect pipeline connections, such as poor product molding, equipment failure, and rework downtime, thus improving production stability and product yield under high-frequency mold change conditions.

[0028] like Figure 2 and Figure 3 As shown, a dedicated cable tray 714 is provided on one side of the automatic docking component 71 on the moving mold side. The dedicated cable tray 714 is connected to the equipment side base plate 711 through the connector 715. All cables and pipelines are neatly arranged on the dedicated cable tray 714.

[0029] In this embodiment, a dedicated cable tray 714 is provided on one side of the automatic docking component 71 on the moving mold side. The dedicated cable tray 714 is fixedly connected to the equipment-side base plate 711 through a connector 715. All cables and pipes are neatly arranged on the dedicated cable tray 714, so that the various cables and pipes that were originally scattered around the injection molding machine have a unified and orderly storage path, avoiding cable tangling, pipe bending, and pulling interference during equipment operation. At the same time, after the cables and pipes are fixed to the dedicated cable tray 714, they move as a whole with the automatic docking component 71 on the moving mold side during mold changing, without the need for manual straightening or avoidance, which greatly reduces the auxiliary time of mold changing operation. In addition, the neat cable and pipe arrangement makes the route of each line clearly identifiable during fault diagnosis, and maintenance personnel can quickly locate abnormal lines, shorten downtime, and further ensure the operational stability and safety of the injection molding production system under high-frequency mold changing conditions.

[0030] like Figure 1 As shown, the transfer station 5 includes a bidirectional conveyor belt 51 and a mold buffer station 52. The bidirectional conveyor belt 51 is located between the first injection molding machine 2 and the second injection molding machine 3. The mold buffer station 52 is used to store molds to be switched.

[0031] In this embodiment, the transfer station 5 is equipped with a bidirectional conveyor belt 51 between the first injection molding machine 2 and the second injection molding machine 3, and a mold buffer station 52 for storing the mold to be changed is set on one side of the bidirectional conveyor belt 51. This realizes the efficient bidirectional flow of molds between the two machines and the pre-positioning of molds before mold change. The mold to be changed can be hoisted to the mold buffer station 52 in advance for storage and waiting. When changing molds, it is directly sent to the corresponding injection molding machine by the bidirectional conveyor belt 51. This eliminates the traditional method of waiting for a crane to hoist large molds from a distant warehouse one by one during mold change, and greatly reduces the mold preparation time and waiting time before mold change. At the same time, the mold buffer station 52, together with the bidirectional conveying function of the bidirectional conveyor belt 51, allows the removal of the old mold and the delivery of the new mold to be completed sequentially on the same conveying path. The transfer path is simple and clear, further shortening the total time of a single mold change, effectively alleviating the problem of equipment production time being squeezed under high-frequency mold change conditions, and improving the overall production capacity and operating efficiency of the dual injection molding machine island.

[0032] like Figure 1 and Figure 2 As shown, the mold 4 is provided with a locking mechanism 9, which includes a mounting plate 91. The mounting plate 91 is connected to the mold 4. Each of the four corners of the mounting plate 91 is connected to a locking cylinder 92. The driving end of the locking cylinder 92 is connected to a locking rod 93. The first injection molding machine 2 and the second injection molding machine 3 are provided with locking holes that are compatible with the locking rod 93.

[0033] In this embodiment, a locking mechanism 9 is provided on the mold 4. The locking mechanism 9 includes a mounting slide plate 91 fixedly connected to the mold 4 and locking cylinders 92 connected to the four corners of the mounting slide plate 91. Each locking cylinder 92 has a locking rod 93 connected to its drive end. The first injection molding machine 2 and the second injection molding machine 3 are respectively provided with locking holes adapted to the locking rods 93. When the mold 4 is moved to the injection molding machine mounting surface with the mounting slide plate 91, the locking cylinders 92 at the four corners synchronously drive the locking rods 93 to extend and insert into the corresponding locking holes, thereby realizing the automatic locking and fixing of the mold 4 on the injection molding machine. This eliminates the traditional method of manually tightening a large number of fastening bolts during mold changing and eliminates the high strength and high consumption of manual locking after the hoisting and alignment of large molds. Simultaneously, locking cylinders 92 are evenly distributed at the four corners of the sliding plate 91, so that the locking force is applied symmetrically and evenly to the four corners of the mold 4, avoiding mold tilting or positioning deviation caused by uneven loading and ensuring mold closing accuracy and product forming quality. In addition, the locking mechanism 9 is transferred as an integral part of the mold 4, locking and unlocking immediately upon positioning. It works in coordination with the bidirectional conveyor belt 51 of the transfer table 5 and the mold buffer station 52 to automate the entire process of mold 4 transfer, locking, unlocking and return without manual intervention. This reduces the time spent on a single mold change and effectively solves the bottleneck problem of the locking process occupying a large amount of effective production time under high-frequency mold change conditions. At the same time, it eliminates the safety hazards in manual locking operations of large molds.

[0034] Among them, the overall control box 6 is electrically connected to the transfer station 5, the docking mechanism 7 and the locking mechanism 9.

[0035] like Figure 1 and Figure 5 As shown, a floating compensation mechanism 10 is provided between the equipment side substrate 711 and the mold side substrate 712. The floating compensation mechanism 10 includes an elastic floating element 101 arranged along the docking direction and a circumferential limiting structure 102.

[0036] In this embodiment, a floating compensation mechanism 10 is provided between the equipment-side substrate 711 and the mold-side substrate 712. The floating compensation mechanism 10 includes an elastic floating element 101 arranged along the docking direction and a circumferential limiting structure 102. When the equipment-side substrate 711 and the mold-side substrate 712 are close to being aligned, the elastic floating element 101 allows the mold-side substrate 712 to generate a small displacement in a plane perpendicular to the docking direction. This automatically compensates for the positional deviation caused by factors such as track positioning error, mounting surface machining tolerance, and equipment thermal deformation after the large mold is transferred to the injection molding machine mounting surface. This ensures that the male and female ends of each connector assembly are precisely aligned, avoiding bending of the connector pins, uneven wear of the sealing ring, or crushing of the housing caused by rigid docking. This addresses issues such as damage; simultaneously, the circumferential limiting structure 102 constrains the compensating motion to a plane perpendicular to the docking direction, limiting the mold-side base plate 712 to only have radial floating degrees of freedom relative to the equipment-side base plate 711, while restricting its rotational degrees of freedom around the docking axis and axial movement along the docking direction. This effectively prevents joint misalignment or sealing failure caused by angular deflection during docking, ensuring reliable mating and sealing performance of all water, electricity, hydraulic, and gas joints under high-frequency mold changing conditions. It solves the industry pain point of interface docking difficulties and frequent joint damage caused by insufficient alignment accuracy of large-tonnage mold transfer, and improves the docking success rate and long-term operational reliability of the multi-media unified automatic docking module under flexible production conditions of multiple varieties and small batches.

[0037] like Figure 1 and Figure 5 As shown, the elastic floating element 101 includes a buffer spring 1011 and a compression spring 1012. The buffer spring 1011 is mounted on the equipment side base plate 711, and the compression spring 1012 is mounted on the mold side base plate 712. One end of the buffer spring 1011 is in contact with one end of the compression spring 1012. The circumferential limiting structure 102 includes multiple limiting cylinders 1021 and multiple limiting slide rods 1022. The multiple limiting cylinders 1021 are mounted on the equipment side base plate 711, and the multiple limiting slide rods 1022 are mounted on the mold side base plate 712. The limiting slide rods 1022 are adapted to the limiting cylinders 1021.

[0038] In this embodiment, the elastic floating element 101 includes a buffer spring 1011 mounted on the equipment-side substrate 711 and a compression spring 1012 mounted on the mold-side substrate 712. One end of the buffer spring 1011 contacts one end of the compression spring 1012. When the equipment-side substrate 711 and the mold-side substrate 712 are aligned, the ends of the two springs are compressed and progressively elastically compressed. Utilizing the nonlinear stiffness characteristics formed by the series connection of the two springs, the radial offset impact of the mold-side substrate 712 is absorbed with lower stiffness in the initial docking stage, avoiding rigid collision damage to the joint. As the compression increases, the stiffness gradually increases to provide a stable centering and restoring force. Compared with a single spring structure, this improves the adaptive compensation capability of the floating compensation mechanism 10 under large sway conditions and the docking compliance. Meanwhile, the circumferential limiting structure 102 includes multiple limiting cylinders 1021 mounted on the equipment-side substrate 711 and a limiting cylinder 1021 mounted on the mold-side substrate 712. Multiple limiting slide rods 1022 on plate 712 are adapted to limit cylinder 1021 to form a sliding guide pair. During the docking process, the floating motion of the mold side plate 712 is precisely constrained in a plane perpendicular to the docking direction, limiting its rotational freedom around the docking axis and axial movement along the docking direction, ensuring that the male and female ends of each joint assembly 73 are always coaxially aligned. The double-stage spring floating system composed of buffer spring 1011 and compression spring 1012 works in conjunction with the guide limiting system composed of limit cylinder 1021 and limiting slide rod 1022. This provides sufficient radial floating tolerance to absorb the position deviation accumulated during the transfer of large-tonnage molds, and ensures that the insertion direction of each joint is unique and accurate during the docking process. This solves the problem of joint eccentric docking caused by deformation due to self-weight and transfer positioning errors of ultra-large-tonnage molds, and improves the success rate of synchronous automatic docking of multi-media interfaces and the service life of joints under high-frequency mold changing conditions.

[0039] Specifically, the system also includes an automatic part-picking robot module and a mold information recognition module. The automatic part-picking robot module is connected to the overall machine control box 6 via signal. After the mold docking and locking and the media interface docking are completed, it automatically matches and switches the part-picking program for the corresponding product. The mold information recognition module is set on the transfer path of the bidirectional conveyor belt 51 or at the injection molding machine mold installation position. It is used to read the mold information stored on the mold during the mold transfer process or after the mold is in place. The overall machine control box 6 automatically calls the injection molding process parameters corresponding to the mold based on the read mold information and synchronously matches the part-picking robot program.

[0040] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
