Under the trend of product precision and high performance, high-end manufacturing fields such as new energy vehicles and smart home appliances have put forward higher requirements for the molding precision of injection molded products.

[0003] Traditional injection molding machines generally suffer from excessive vibration due to structural design limitations. This vibration not only affects the dimensional stability and surface quality of the product, but also accelerates mold fatigue and wear, shortens mold life, and the accompanying noise pollution worsens the working environment, which is inconsistent with the development direction of modern green manufacturing. Therefore, developing a high-efficiency vibration damping structure that can effectively suppress mechanical vibration during the injection molding process and improve the stability of equipment operation and processing accuracy has become a key technical problem that the industry urgently needs to solve. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a vibration-damping coupling installation structure for motor pump units and machine frames, as well as an injection molding machine, which is simple in structure, easy to assemble, safe and reliable, and has a significant vibration-damping effect.

[0005] The objective of this utility model can be achieved through the following technical solution: a vibration-damping coupling installation structure for a motor-pump unit and a frame is proposed, comprising a frame, several vibration-damping rubber pads, a motor support plate, a motor bracket, and a power module, wherein:

[0006] The power module can be detachably mounted on the motor bracket;

[0007] Several arrays of the aforementioned shock-absorbing rubber are distributed within the frame to absorb the vibration energy generated by the power module, and the motor support plate is connected between two adjacent shock-absorbing rubbers along the length of the frame.

[0008] The motor bracket is mounted on the motor support plate, and the motor bracket can drive the motor support plate to move relative to the motor support plate, which is used to adjust the center of gravity of the power module to suppress the transmission of vibration during its operation.

[0009] In the above-mentioned vibration-damping coupling installation structure for motor pump set and frame, the motor support plate is provided with a waist-shaped hole, the motor bracket is provided with a support seat, and the support seat is provided with a locking hole that communicates with the waist-shaped hole.

[0010] In the above-mentioned vibration-damping coupling mounting structure for motor pump unit and frame, the power module includes a drive motor and a pump body. The motor bracket is provided with mounting holes and a first mounting seat and a second mounting seat located at the two ports on both sides of the mounting holes. The drive motor and the pump body are detachably connected to the first mounting seat and the second mounting seat, respectively.

[0011] In the above-mentioned vibration-damping coupling installation structure for motor pump set and frame, the oil suction end of the pump body is equipped with an oil suction flange, and the oil suction flange and the oil tank in the frame are flexibly connected through hydraulic oil pipes.

[0012] In the above-mentioned vibration-damping coupling installation structure for motor pump set and frame, the motor support plate is also provided with an assembly hole for fasteners to pass through, so as to restrict the movement of the motor support plate relative to the vibration damping rubber.

[0013] In the above-mentioned vibration-damping coupling mounting structure for motor pump unit and frame, the motor bracket is further provided with a clearance hole located between the first mounting base and the second mounting base, and the clearance hole is connected to the mounting hole.

[0015] In the above-mentioned vibration-damping coupling mounting structure for motor pump unit and frame, the output shaft of the drive motor is connected to the pump body through an internal spline structure.

[0016] In the above-mentioned vibration damping coupling installation structure for motor pump unit and frame, the vibration damping rubber also has an extension portion, and the extension portion has a connecting hole, which allows bolts or screws to fix the vibration damping rubber to the frame.

[0017] The technical solution adopted by this utility model to solve its technical problem is to also propose an injection molding machine, including one of the above-mentioned shock-absorbing coupling installation structures for the motor pump unit and the machine frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention provides a shock-absorbing coupling installation structure for motor pump set and frame and injection molding machine. Through the flexible connection of shock-absorbing rubber, motor support plate and hydraulic oil pipe, the structure constructs a multi-level shock absorption system, which can effectively suppress the vibration generated during equipment operation, significantly reduce the vibration amplitude of the equipment, and thus achieve a significant shock absorption effect.

[0020] (2) The design of the waist-shaped hole allows for fine adjustment of the installation position of the motor support plate, thereby better adapting to the actual installation situation of the equipment and improving the accuracy and efficiency of assembly.

[0021] (3) The design of the clearance hole reduces the material used in the motor bracket as a whole, reducing manufacturing costs. At the same time, the connection between the clearance hole and the mounting hole helps workers to observe the actual installation of the drive motor and pump body during the assembly process, ensuring the stability of the entire power module during operation.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figure 1 As shown, this solution mainly describes a vibration-damping coupling mounting structure for a motor pump unit and frame 1 used in an injection molding machine. However, this vibration-damping coupling mounting structure for a motor pump unit and frame 1 is not limited to use in injection molding machines, but can also be applied to other installation equipment that requires vibration damping.

[0029] like Figures 1 to 3As shown, a vibration-damping coupling installation structure for a motor pump unit and a frame 1 includes a frame 1, several vibration-damping rubbers 2, a motor support plate 3, a motor bracket 4, and a power module 5.

[0030] The power module 5 is detachably mounted on the motor bracket 4; several shock-absorbing rubbers 2 are arrayed inside the frame 1 to absorb the vibration energy generated by the power module 5; a motor support plate 3 is connected between two adjacent shock-absorbing rubbers 2 along the length of the frame 1; the motor bracket 4 is mounted on the motor support plate 3, and the motor bracket 4 can drive the motor support plate 3 to move relative to the motor support plate 3 to adjust the center of gravity of the power module 5 to suppress the vibration transmission during its operation.

[0031] Specifically, such as Figures 1 to 3 As shown, firstly, workers distribute several shock-absorbing rubbers 2 in a predetermined pattern within the frame 1 (in this embodiment, they are arranged in a symmetrical matrix, but the arrangement of the shock-absorbing rubbers 2 is not limited to this embodiment). When the power module 5 starts running, the vibration energy generated will be absorbed by the shock-absorbing rubbers 2 distributed within the frame 1. As a key component, the shock-absorbing rubber 2 can effectively reduce the transmission of vibration to the frame 1 and other parts, and reduce the overall vibration level of the machine. Therefore, the shock-absorbing rubber 2 forms the first damping function for the power module 5. Because a motor support plate 3 connects the two shock-absorbing rubber pads 2 along the length of the frame 1, and both the power module 5 and the motor bracket 4 are placed on the motor support plate 3, the motor support plate 3 can be moved relative to the power module 5. It should be noted that the center of gravity of the power module 5 is not located on the motor bracket 4. By adjusting the position of the power module 5 and the motor bracket 4 relative to the motor support plate 3, the center of gravity of the entire installation structure can be shifted, ensuring optimal balance. This not only suppresses vibration transmission from the power module 5 during operation but also enhances the stability of the entire system. Therefore, this shifting adjustment method provides a second layer of vibration damping for the power module 5. With the complementary effects of the first and second vibration damping mechanisms, this structure, with its modular design and convenient assembly / disassembly, simplifies the maintenance and repair process, reduces maintenance time and costs, and improves the availability and reliability of the equipment.

[0032] The motor support plate 3 has a waist-shaped hole 30, and the motor bracket 4 has a support seat 40. The support seat 40 has a locking hole 400 that communicates with the waist-shaped hole 30.

[0033] like Figure 2 and Figure 3As shown, in this embodiment, the motor support plate 3 adopts a parallel extension structure design (i.e., the two motor support plates 3 used in this embodiment are arranged in parallel within the frame 1). When it is necessary to adjust the position of the power module 5 (such as center of gravity, eccentric load compensation), the operator loosens the connecting bolts (such as screws or bolts passing through the locking hole 400 and inserted into the oblong hole 30). At this time, the motor bracket 4 can slide freely on the motor support plate 3 along the length direction of the oblong hole 30, thereby driving the power module 5 along the length direction of the oblong hole 30. Figure 2 The lateral position (i.e., left-right direction) is finely adjusted to better adapt to the actual installation of the equipment. This also shifts the center of gravity of the power module 5 and motor bracket 4, eliminating vibrations caused by uneven mass distribution in the power module 5 and effectively compensating for the inherent center of gravity shift, thus achieving vibration reduction. Compared to the traditional structure where the motor bracket 4 is directly mounted on the vibration damping rubber 2, this significantly reduces vibration noise, especially when multiple power modules 5 are installed on a single machine, achieving excellent vibration reduction.

[0034] The power module 5 includes a drive motor 50 and a pump body 51. The motor bracket 4 is provided with a mounting hole 41 and a first mounting seat 42 and a second mounting seat 43 located on both sides of the mounting hole 41. The drive motor 50 and the pump body 51 are detachably connected to the first mounting seat 42 and the second mounting seat 43, respectively.

[0035] like Figure 2 As shown, the power module 5 in this embodiment mainly consists of a drive motor 50 and a pump body 51 (which can be an oil pump or a gear pump). During installation, the operator aligns the drive motor 50 with the first mounting base 42 and the pump body 51 with the second mounting base 43, ensuring that its output shaft is aligned through the mounting hole 41 on the motor bracket 4. Using bolts, clips, or other quick-change fasteners, the drive motor 50 and pump body 51 are securely mounted on the corresponding first and second mounting bases 43. This installation structure is relatively simple, facilitating disassembly and replacement during subsequent maintenance and replacement, thus improving work efficiency. Preferably, in this embodiment, the output shaft of the drive motor 50 and the pump body 51 are connected by an internal spline structure. The mounting hole 41 ensures a secure and stable connection between the drive motor 50 and the pump body 51, guaranteeing connection accuracy. Furthermore, the internal spline structure has a large contact area, enabling the transmission of high torque within a small space, making it ideal for applications requiring high power transmission, such as injection molding machines.

[0036] The motor support plate 3 is also provided with mounting holes 31, through which fasteners pass to restrict the movement of the motor support plate 3 relative to the shock absorber 2.

[0037] Furthermore, such as Figure 2 and Figure 3As shown, before installation between the motor support plate 3 and the vibration damping adhesive 2, several vibration damping adhesives 2 need to be arrayed in a predetermined pattern within the frame 1. As the mounting holes 31 at both ends of the motor support plate 3 correspond to the vibration damping adhesives 2 to be connected, workers use bolts, screws, or other types of fasteners to pass through the mounting holes 31 on the motor support plate 3 and fix it to the fixing point of the vibration damping adhesive 2. This effectively limits the displacement of the motor support plate 3 relative to the vibration damping adhesive 2 or the frame 1, thereby ensuring the stability of the motor bracket 4, its drive motor 50, and the pump body 51 during operation, preventing the motor support plate 3 from loosening and resonating with the power module 5 during operation. Preferably, this embodiment can also have multiple mounting holes 31 (not shown in the figure) on the motor support plate 3, allowing the same motor support plate 3 to adapt to different power modules 5 (i.e., equipped with different power units), greatly improving the versatility and scalability of the equipment.

[0038] The oil suction end of the pump body 51 is equipped with an oil suction flange 510, and the oil suction flange 510 is flexibly connected to the oil tank 6 inside the frame 1 through a hydraulic oil pipe 60.

[0039] like Figure 2 As shown, in this embodiment, an oil suction flange 510 is pre-installed at the oil suction end (i.e., the oil suction port) of the pump body 51. The design of the oil suction flange 510 must ensure that it can form a good sealing connection with the subsequently connected hydraulic oil pipe 60 to avoid oil leakage. Starting from the oil suction flange 510, one or more sections of hydraulic oil pipe 60 are used to connect the pump body 51 to the oil tank 6 inside the frame 1. It should be noted that the flexible connection referred to in this embodiment means that the material of the hydraulic oil pipe 60 should have a certain degree of flexibility to adapt to small displacements or vibrations that may occur during equipment operation (i.e., reduce the vibration amplitude) without causing stress concentration or pipe rupture due to rigid connection. This structure also forms a third vibration damping function. Preferably, in this embodiment, a rubber connection part (not shown in the figure) can also be provided between the oil suction flange 510 and the oil tank 6 of the injection molding machine to further improve the overall sealing function.

[0040] The motor bracket 4 also has a clearance hole 44 located between the first mounting base 42 and the second mounting base 43, and the clearance hole 44 is connected to the mounting hole 41.

[0041] Furthermore, such as Figure 2As shown, during the installation of the drive motor 50 and pump body 51, workers can easily observe the shaft alignment between the drive motor 50 and pump body 51 through the clearance hole 44, assisting operators in making precise adjustments. Good alignment helps reduce vibration and noise during transmission, extending the service life of the equipment. In addition, the clearance hole 44 also plays a role in ventilation and heat dissipation to a certain extent, which is conducive to the heat dissipation between the drive motor 50 and pump body 51 and prevents local overheating from affecting equipment performance.

[0042] Preferably, the vibration damping adhesive 2 in this embodiment is a layered silicon-based composite material. This design allows for optimized processing of vibrations in different frequency bands, achieving more comprehensive and effective vibration isolation. Compared to vibration damping adhesive 2 made of a single material, it can effectively reduce vibration levels over a wider range. By precisely controlling the proportion and thickness of each layer of material, the overall stiffness and flexibility of the vibration damping adhesive 2 can be adjusted, enabling it to provide sufficient support strength while flexibly responding to complex dynamic load changes, further enhancing the operational stability of the entire system.

[0043] More preferably, such as Figure 2 As shown, this embodiment also includes an extension 20 formed on the shock-absorbing adhesive 2, with a connecting hole 200 provided on the extension 20. The connecting hole 200 allows bolts or screws to be used to fix the shock-absorbing adhesive 2 to the frame 1. By relying on the shock-absorbing adhesive 2 to create an elastic contact interface between the motor support plate 3 and the frame 1, combined with the application of layered shock-absorbing materials, the vibration wave transmission efficiency can be significantly reduced, thereby effectively reducing the resonance of the frame 1 and achieving a vibration reduction effect.

[0044] It should be noted that the drive motor 50 in this embodiment can be replaced by other drive devices such as servo motors and stepper motors.
