Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically a high-precision motion trajectory control and execution device for all-electric injection molding machines. Background Technology

[0002] As is well known, the high-precision motion trajectory control actuator of an all-electric injection molding machine consists of two main parts: one part is the mechanical actuators that directly realize the motion (such as servo motors, ball screws, guide rails, and linear encoders), which are distributed and installed on the injection unit, template, and other mechanical bodies of the injection molding machine, and are the "executors" of physical motion; the other part is the control core, namely the motion control card, servo driver, PLC, and other electronic components integrated in the control box, which is the "carrier" of these core control modules.

[0003] The core component of the high-precision motion trajectory control actuator of existing all-electric injection molding machines—the control box—has significant deficiencies in its protective design: the four corners of the control box are mostly sharp right angles without any rounding or cushioning. In scenarios where personnel frequently operate the machine, such as laboratories and workshops, workers are very likely to accidentally bump into the sharp corners due to the compact layout of the equipment and the need for movement and turning. This can not only cause injuries such as cuts and bruises, but also affect the stability of the motion control module due to the impact force transmitted into the box, thus indirectly affecting the trajectory control accuracy of the injection molding machine. It fails to meet both the safety requirements of personnel operation and the protection requirements of equipment operation. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a high-precision motion trajectory control execution device for an all-electric injection molding machine, which has the following beneficial effects:

[0015] This high-precision motion trajectory control actuator for an all-electric injection molding machine features two key improvements. First, a protective shell fitted onto the outer wall of the control box effectively protects the sharp corners of the control box. The rubber layer on the outer wall of the protective shell cushions external impacts, preventing damage to internal control components and eliminating the risk of bumps to operators from sharp edges, significantly enhancing operator safety and equipment protection. Second, a symmetrically designed connecting mechanism and a precisely matched slider groove structure ensure that the protective shell fits firmly and securely after installation, preventing shifting or loosening due to equipment vibration. Furthermore, the electrical connection between the control button and the electric push rod allows operators to quickly unlock the limit mechanism, facilitating easy disassembly and replacement of the protective shell without complex operations. Finally, the precise fit between the protective shell and the main body reduces the entry of external dust and water, indirectly protecting the internal control module and ensuring long-term stable operation of the injection molding machine's trajectory control actuator, fully adapting to the needs of industrial applications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4A high-precision motion trajectory control and execution device for an all-electric injection molding machine includes a body 1, a protective shell 2, a connecting mechanism 4, and a limiting mechanism 9. The protective shell 2 is fitted onto the outer wall of the body 1. The body 1 is equipped with a control button 3, which is electrically connected to the body 1. The connecting mechanism 4 includes a first sliding groove 5, a first slider 6, a second sliding groove 7, a second slider 8, and a slot 14. The first sliding groove 5 is formed on the top of the protective shell 2. One end of the first slider 6 extends into the first sliding groove 5. The second sliding groove 7 is formed on the first slider 6. One end of the second slider 8 extends into the second sliding groove 7. The slot 14 is formed on the protective shell 2. On the shell 2, the slot penetrates the protective shell 2 and is formed on the top of the body 1. The other end of the second slider 8 extends into the slot. There are two connecting mechanisms 4. The limiting mechanism 9 includes a bearing 10, a rotating block 11, an electric push rod 12, and a locking block 13. The bearing 10 is set on the top of the body 1. One end of the rotating block 11 is connected to the top of the body 1 through the bearing 10. The other end of the rotating block 11 abuts against the top of the second slider 8. One end of the electric push rod 12 is connected to the rotating block 11. The other end of the electric push rod 12 is connected to the locking block 13. One end of the locking block 13 extends into the top of the first slider 6.

[0023] Working principle

[0024] The main body 1 in this device is the control box of a conventional all-electric injection molding machine high-precision motion trajectory control execution device. The core components such as motion control card and servo driver integrated inside, as well as the trajectory control working principle, are common knowledge to those in this technical field and will not be elaborated here. In daily use, the protective shell 2 is fitted on the outer wall of the main body 1, which can completely cover the sharp parts of the four corners of the main body 1 to prevent workers from being injured due to accidental bumps to the sharp parts.

[0025] When the protective shell 2 becomes damaged after long-term use and needs to be replaced, the operating procedure is as follows (for reference). Figure 1First, the operator activates the electric push rod 12. The electric push rod 12 retracts, causing the locking block 13 to disengage from the pre-set slot on the top of the first slider 6, thus releasing the restriction on the first slider 6. Then, the operator pushes the first slider 6, causing it to slide along the first groove 5 on the top of the protective shell 2 to the other end of the groove. During this process, the second slider 8, which is connected to the first slider 6, will simultaneously slide along the slot 14 to the corresponding position. At this time, the end of the rotating block 11 no longer abuts against the first slider 6. Next, using the bearing 10 as the rotation axis, the rotating block 11, which is connected to the top of the body 1, is rotated 90° to support the rotation. Block 11 remains stable, completely separating it from the second slider 8; then push the second slider 8, causing it to rise vertically along the second groove 7 on the first slider 6 until the second slider 8 disengages from the groove 14—since the groove 14 penetrates the protective shell 2 and extends to the top of the main body 1, this operation can completely separate the second slider 8 from the main body 1 and the protective shell 2; finally, the operator pushes the protective shell 2 to remove it from the outer wall of the main body 1 and replace it with a new protective shell (the new protective shell can be obtained through regular procurement from the manufacturer). After replacement, the installation can be completed by reversing the steps.

[0026] To further enhance the dual protection of the protective shell for both the main body and personnel, and to accommodate potential collisions and bumps around the control box of the all-electric injection molding machine, this embodiment adds a rubber layer to the outer wall of the protective shell 2. This rubber layer is tightly fixed to the outer wall of the protective shell 2 using conventional bonding processes, ensuring that it will not detach or lift due to equipment vibration or daily contact during long-term use. The rubber layer itself has good elasticity and cushioning performance, which can absorb impact energy through its own deformation when the protective shell 2 is subjected to external force, preventing the impact force from being transmitted to the internal main body 1 and affecting the stability of the control components. It can also wrap the edges and corners of the protective shell 2, further reducing the risk of injury to personnel from accidental bumps. At the same time, the rubber material can also improve the anti-slip properties of the outer wall of the protective shell 2, making it easier for personnel to move or adjust the position of the protective shell, thus comprehensively improving the protective practicality and safety of the device.

[0027] To further improve the operational stability of the connecting mechanism during the installation, disassembly, and daily use of the protective shell, and to prevent loosening and jamming caused by excessive clearance between the slider and the slide groove, ensuring that the protective shell is always securely fitted onto the body, this embodiment adopts a design where the first slider 6 is precisely matched with the first slide groove 5, and the second slider 8 is precisely matched with the second slide groove 7. The matching of the two is reflected in both dimensional accuracy and shape adaptation. The outer wall dimension of the first slider 6 and the inner wall dimension of the first slide groove 5, and the outer wall dimension of the second slider 8 and the inner wall dimension of the second slide groove 7, all maintain a minimal clearance. Moreover, the cross-sectional shape of the slider and the corresponding slide groove is completely consistent (such as rectangular, square, etc.). This design not only ensures that the first slider 6 slides smoothly along the first slide groove 5 and the second slider 8 slides smoothly along the second slide groove 7, but also provides reliable lateral restraint for the slider through the slide groove, preventing the slider from shifting or shaking under force. This provides a solid structural support for the stable installation and convenient disassembly of the protective shell, and avoids affecting the protective effect due to loose fit.

[0028] To further enhance the support stability of the connecting mechanism for the protective shell and prevent the protective shell from tilting or loosening due to uneven force, ensuring its long-term stable fit to the body, this embodiment adopts a symmetrical arrangement of the two connecting mechanisms 4. Specifically, the two connecting mechanisms 4 are symmetrically distributed along the longitudinal central axis of the body 1 and the protective shell 2, and are respectively installed on both sides of the top of the protective shell 2. This symmetrical layout allows the protective shell 2 to receive equal limiting support force from the connecting mechanisms on both sides during installation, avoiding excessive force on one side that could cause the protective shell to shift. At the same time, during daily use or disassembly of the protective shell, the symmetrically distributed connecting mechanisms can synchronously transmit forces, preventing the protective shell from shaking due to unilateral operation, ensuring the matching accuracy of the slider and the groove, and thus ensuring that the protective shell is always precisely fitted to the body, providing a reliable guarantee for the overall structural stability and protective effect of the device.

[0029] To further enhance the stability and reliability of the protective shell's coverage of the main body and avoid excessive gaps, wobbling, or displacement due to poor compatibility between the protective shell and the main body, this embodiment adopts a design that precisely matches the protective shell 2 with the main body 1. This matching is reflected in both the external contour and dimensional accuracy. The inner cavity shape of the protective shell 2 is completely consistent with the outer wall contour of the main body 1, and the length, width, and height dimensions of the inner cavity of the protective shell 2 maintain a minimal fit gap with the external dimensions of the main body 1. This ensures that the protective shell 2 fits tightly against the outer wall of the main body 1 when installed. This design effectively limits the lateral and longitudinal displacement of the protective shell 2 on the outer wall of the main body 1, preventing the protective shell from shaking due to vibration during equipment operation. Simultaneously, the tightly fitted structure reduces the possibility of external dust and water entering the main body 1 through gaps, ensuring the installation stability of the protective shell and indirectly improving the protection effect on the internal control components of the main body, thus ensuring the overall reliable operation of the device.

[0030] To further enhance the ease and efficiency of device operation and avoid the need for operators to operate other control components to adjust the limit mechanism, this embodiment establishes an electrical connection between the control button 3 and the electric push rod 12. Operators can directly send extension and retraction control signals to the electric push rod 12 through the control button 3 on the main body 1, without the need for external control equipment or complex operating procedures. This design can greatly simplify the operation steps when disassembling and replacing the protective shell. When it is necessary to unlock the limit mechanism, simply press the control button 3 to drive the electric push rod 12 to retract, causing the locking block to separate from the first slider. When locking later, the electric push rod 12 can also be extended and reset through the control button 3. The entire process does not require manual adjustment of the mechanical structure, which reduces the difficulty of operation and the probability of operational errors, ensuring that operators can quickly and smoothly complete the relevant operations of the protective shell 2, meeting the high-efficiency needs of daily equipment maintenance.
