[0025] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: As Figures 1 to 6 and Figure 8 The illustrated motor-assisted installation device includes a lifting mechanism 1 and a sliding frame 2. The sliding frame 2 is arranged on the lifting mechanism 1. The lifting mechanism 1 can drive the sliding frame 2 to move up and down, thereby adjusting the height position of the sliding frame 2 so that the sliding frame 2 can be aligned with the installation position of the motor 12 on the injection molding machine 11. The sliding frame 2 includes a support plate 2.2 and a fixed platform 2.1. The support plate 2.2 can slide relative to the fixed platform 2.1. When the sliding frame 2 reaches the corresponding height position, the motor 12 on the support plate 2.2 can be moved to the injection molding machine 11 for installation by moving the position of the support plate 2.2. This solution can solve the problem of low installation efficiency caused by the weight of the drive motor itself and the internal space limitation of the injection molding machine, improving the user's installation efficiency and saving effort.

[0027] Specifically, the lifting mechanism 1 includes a base plate 1.1, a screw 1.2, and a rotating disk 1.3. The rotating disk 1.3 is rotatably connected to the base plate 1.1 and can rotate circumferentially. The rotating disk 1.3 is circular and has a connecting frame in the middle for easy operation. The rotating disk 1.3 has a threaded hole in the middle, and the screw 1.2 and rotating disk 1.3 are threaded together. Rotating the rotating disk 1.3 causes the screw 1.2 to spiral up or down, achieving the up-and-down movement of the screw 1.2. A sliding frame 2 is fixed to the top of the screw 1.2. When the screw 1.2 moves up and down, the sliding frame 2 moves up and down as well. It should be noted that because the screw 1.2 is adjusted by a screw connection, this improves the vertical movement accuracy of the screw 1.2, allowing for better adjustment of the height of the sliding frame 2 and improving its positional accuracy. This makes the installation of the motor 12 more convenient and its position more accurate.

[0028] Four sets of casters 6 are also provided on the base plate 1.1. The base plate 1.1 has a rectangular plate structure, and the four sets of casters 6 are respectively located at the four corners of the base plate 1.1, which can realize the adjustment of the base plate 1.1 in any direction and can better adjust the extension direction of the sliding frame 2. The casters 6 are also provided with a locking mechanism, which can lock the casters 6. When the motor-assisted mounting device moves to the designated position, the locking mechanism is adjusted to lock the casters 6, and the overall position of the device is fixed. After the motor 12 is installed, the locking mechanism is opened again, and the device can be moved again.

[0029] It should be noted that a bearing 13 is also provided between the screw 1.2 and the sliding frame 2, which allows the sliding frame 2 and the screw 1.2 to rotate, making it easier to adjust the angle of the sliding frame 2.

[0030] The sliding frame 2 includes a fixed platform 2.1 and a support plate 2.2. The fixed platform 2.1 is a rectangular platform, and its dimensions are similar to those of the base plate 1.1. The lower part of the fixed platform 2.1 is connected to the screw 1.2, and the upper part of the fixed platform 2.1 has a recessed sliding groove. Specifically, a linear guide rail 2.1.2 is provided above the fixed platform 2.1, and a guide rail groove 2.2.1 adapted to the linear guide rail 2.1.2 is provided at the bottom of the support plate 2.2. The end cross-sections of the linear guide rail 2.1.2 and the guide rail groove 2.2.1 are approximately "I" shaped. The support plate 2.2 is slidably connected to the linear guide rail 2.1.2 through the guide rail groove 2.2.1 to ensure the stability of the sliding of the support plate 2.2.

[0031] A plurality of first rolling bodies 4 are arranged on both sides of the fixed platform 2.1 and parallel to the linear guide rail 2.1.2. The first rolling bodies 4 are cylindrical roller pieces, the axial direction of the first rolling bodies 4 is horizontally arranged, and the middle position of the first rolling bodies 4 is recessed. After the support plate 2.2 and the linear guide rail 2.1.2 are matched, the two sides of the support plate 2.2 abut on the first rolling bodies 4, and the bottom of the support plate 2.2 is provided with a convex strip 2.2.2 matched with the recess of the first rolling body 4, so as to ensure the rolling effect of the support plate 2.2 and the first rolling body 4, and greatly reduce the movement friction of the support plate 2.2.

[0032] A guide edge 2.1.3 is further arranged on both sides of the fixed platform 2.1, and a guide groove 2.2.3 matched with the guide edge 2.1.3 is arranged on the support plate 2.2, so as to further ensure the movement stability between the support plate 2.2 and the fixed platform 2.1. In addition, a limiting table 2.1.1 is further arranged at one end of the fixed platform 2.1, and the limiting table 2.1.1 is located in the sliding direction of the support plate 2.2. The limiting table 2.1.1 can prevent the support plate 2.2 from sliding out of one end of the fixed platform 2.1.

[0033] A one-way limiting assembly 3 is further arranged on the fixed platform 2.1. The one-way limiting assembly 3 is arranged symmetrically on both sides of the linear guide rail 2.1.2, and two avoiding grooves 2.3 are arranged on the support plate 2.2. The one-way limiting assembly 3 is arranged in the avoiding groove 2.3, and when the support plate 2.2 moves on the fixed platform 2.1, the one-way limiting assembly 3 does not interfere with the movement of the support plate 2.2 in the avoiding groove 2.3.

[0034] Specifically, the one-way limiting assembly 3 comprises a fixed seat 3.1, a swing block 3.2 and an elastic piece 3.3. The fixed seat 3.1 is a reverse U-shaped structure, one end of the swing block 3.2 is rotatably connected in the U-shaped opening of the fixed seat 3.1, the other end of the swing block 3.2 is lapped on the elastic piece 3.3, one end of the elastic piece 3.3 is connected with the swing block 3.2, and the other end of the elastic piece 3.3 is fixed on the fixed platform 2.1. The side of the swing block 3.2 close to the limiting table 2.1.1 is a circular arc guide surface 7, and the other side is a stop surface 8. When the motor 12 is placed on the support plate 2.2 and the support plate 2.2 moves outward to the injection molding equipment 11 (the body of the injection molding equipment), the swing block 3.2 is in the state of being lapped on the elastic piece 3.3, and the swing block 3.2 is in the state of being lapped on the elastic piece 3.3. Figure 8As shown, the motor 12 applies downward pressure to the swing block 3.2, pressing it down. At this time, the one-way limiting component 3 does not obstruct the movement of the support plate 2.2 and the motor 12. After the support plate 2.2 and the motor 12 have moved into position, the position of the motor 12 exceeds the position of the one-way limiting component 3. The swing block 3.2 loses pressure and is lifted by the elastic element 3.3. At this time, the support plate 2.2 moves in the opposite direction. Under the action of the stop surface 8 of the swing block 3.2, the motor 12 cannot follow the support plate 2.2 back to move. Thus, the motor 12 will be left on the injection molding equipment 11, avoiding manual handling of the motor 12.

[0035] A second rolling element 5 is also provided on the side of the support plate 2.2 away from the limiting platform 2.1.1. Specifically, there are four sets of the second rolling elements 5. Two sets of the second rolling elements 5 are arranged at the bottom of the support plate 2.2, symmetrical about the guide rail groove 2.2.1, and two other sets of the second rolling elements 5 are arranged on the outside of both sides of the guide rail groove 2.2.1. The second rolling elements 5 can make the movement of the support plate 2.2 more stable, so that the extended end of the support plate 2.2 can roll on the fixed platform 2.1.

[0036] It should be noted that a force application handle 10 is also provided on the support plate 2.2. The force application handle 10 is located on the side of the support plate 2.2 near the limit table 2.1.1. The force application handle 10 allows the operator to more conveniently operate the support plate 2.2 on the sliding frame 2.

[0037] Example 2: As Figures 1 to 5 and Figures 7 to 8 The illustrated motor-assisted installation device includes a lifting mechanism 1 and a sliding frame 2. The sliding frame 2 is arranged on the lifting mechanism 1. The lifting mechanism 1 can drive the sliding frame 2 to move up and down, thereby adjusting the height position of the sliding frame 2 so that the sliding frame 2 can be aligned with the installation position of the motor 12 on the injection molding machine 11. The sliding frame 2 includes a support plate 2.2 and a fixed platform 2.1. The support plate 2.2 can slide relative to the fixed platform 2.1. When the sliding frame 2 reaches the corresponding height position, the motor 12 on the support plate 2.2 can be moved to the injection molding machine 11 for installation by moving the position of the support plate 2.2. This solution can solve the problem of low installation efficiency caused by the weight of the drive motor itself and the internal space limitation of the injection molding machine, improving the user's installation efficiency and saving effort.

[0038] Specifically, the lifting mechanism 1 includes a base plate 1.1, a screw 1.2, and a rotating disk 1.3. The rotating disk 1.3 is rotatably connected to the base plate 1.1 and can rotate circumferentially. The rotating disk 1.3 is circular and has a connecting frame in the middle for easy operation. The rotating disk 1.3 has a threaded hole in the middle, and the screw 1.2 and rotating disk 1.3 are threaded together. Rotating the rotating disk 1.3 causes the screw 1.2 to spiral up or down, achieving the up-and-down movement of the screw 1.2. A sliding frame 2 is fixed to the top of the screw 1.2. When the screw 1.2 moves up and down, the sliding frame 2 moves up and down as well. It should be noted that because the screw 1.2 is adjusted by a screw connection, this improves the vertical movement accuracy of the screw 1.2, allowing for better adjustment of the height of the sliding frame 2 and improving its positional accuracy. This makes the installation of the motor 12 more convenient and its position more accurate.

[0039] Four sets of casters 6 are also provided on the base plate 1.1. The base plate 1.1 has a rectangular plate structure, and the four sets of casters 6 are respectively located at the four corners of the base plate 1.1, which can realize the adjustment of the base plate 1.1 in any direction and can better adjust the extension direction of the sliding frame 2. The casters 6 are also provided with a locking mechanism, which can lock the casters 6. When the motor-assisted mounting device moves to the designated position, the locking mechanism is adjusted to lock the casters 6, and the overall position of the device is fixed. After the motor 12 is installed, the locking mechanism is opened again, and the device can be moved again.

[0040] It should be noted that a bearing 13 is also provided between the screw 1.2 and the sliding frame 2, which allows the sliding frame 2 and the screw 1.2 to rotate, making it easier to adjust the angle of the sliding frame 2.

[0041] The sliding frame 2 includes a fixed platform 2.1 and a support plate 2.2. The fixed platform 2.1 is a rectangular platform, and its dimensions are similar to those of the base plate 1.1. The lower part of the fixed platform 2.1 is connected to the screw 1.2, and the upper part of the fixed platform 2.1 has a recessed sliding groove. Specifically, a linear guide rail 2.1.2 is provided above the fixed platform 2.1, and a guide rail groove 2.2.1 adapted to the linear guide rail 2.1.2 is provided at the bottom of the support plate 2.2. The end cross-sections of the linear guide rail 2.1.2 and the guide rail groove 2.2.1 are approximately "I" shaped. The support plate 2.2 is slidably connected to the linear guide rail 2.1.2 through the guide rail groove 2.2.1 to ensure the stability of the sliding of the support plate 2.2.

[0042] A plurality of first rolling bodies 4 are arranged on both sides of the fixed platform 2.1 and parallel to the linear guide rail 2.1.2. The first rolling bodies 4 are cylindrical roller pieces, the axial direction of the first rolling bodies 4 is horizontally arranged, and the middle position of the first rolling bodies 4 is recessed. After the support plate 2.2 and the linear guide rail 2.1.2 are matched, the two sides of the support plate 2.2 abut on the first rolling bodies 4, and the bottom of the support plate 2.2 is provided with a convex strip 2.2.2 matched with the recess of the first rolling body 4, so as to ensure the rolling effect of the support plate 2.2 and the first rolling body 4, and greatly reduce the movement friction of the support plate 2.2.

[0043] A guide edge 2.1.3 is further arranged on both sides of the fixed platform 2.1, and a guide groove 2.2.3 matched with the guide edge 2.1.3 is arranged on the support plate 2.2, so as to further ensure the movement stability between the support plate 2.2 and the fixed platform 2.1. In addition, a limiting table 2.1.1 is further arranged at one end of the fixed platform 2.1, and the limiting table 2.1.1 is located in the sliding direction of the support plate 2.2. The limiting table 2.1.1 can prevent the support plate 2.2 from sliding out of one end of the fixed platform 2.1.

[0044] A one-way limiting assembly 3 is further arranged on the fixed platform 2.1. The one-way limiting assembly 3 is arranged symmetrically on both sides of the linear guide rail 2.1.2, and an avoiding groove 2.3 is arranged on the support plate 2.2. The avoiding groove 2.3 is also provided with two avoiding grooves, and the one-way limiting assembly 3 is arranged in the avoiding groove 2.3. When the support plate 2.2 moves on the fixed platform 2.1, the one-way limiting assembly 3 does not interfere with the movement of the support plate 2.2 in the avoiding groove 2.3.

[0045] Specifically, the one-way limiting assembly 3 includes a lifting block 9 and an elastic piece 3.3. The inside of the lifting block 9 is a hollow body, and the elastic piece 3.3 is arranged in the inside of the lifting block 9. One end of the elastic piece 3.3 is fixedly connected with the fixed platform 2.1, and the other end of the elastic piece 3.3 abuts against the inside of the lifting block 9. The side of the lifting block 9 close to the limiting table 2.1.1 is a circular arc guide surface 7, and the other side is a stop surface 8. When the motor 12 is placed on the support plate 2.2 and the support plate 2.2 moves outward to the injection molding equipment 11 (the body of the injection molding equipment), the motor 12 will exert a downward pressure on the lifting block 9, and the lifting block 9 will be pressed down. At this time, the one-way limiting assembly 3 does not block the movement of the support plate 2.2 and the motor 12. When the support plate 2.2 and the motor 12 are moved to the position, the position of the motor 12 exceeds the position of the one-way limiting assembly 3, the lifting block 9 loses the pressure and is lifted by the elastic piece 3.3. At this time, the support plate 2.2 moves reversely, and the motor 12 cannot return to the movement with the support plate 2.2 under the action of the stop surface 8 of the lifting block 9, so that the motor 12 will be left on the injection molding equipment 11, avoiding manual carrying of the motor 12. Figure 8 ​

[0046] On the side of the support plate 2.2 away from the limiting table 2.1.1, a second rolling body 5 is further arranged. Specifically, the second rolling body 5 is arranged in four groups, and at the end of the support plate 2.2 away from the limiting table 2.1.1, two groups of second rolling bodies 5 are arranged at the bottom of the support plate 2.2 and are symmetrically located with respect to the guide groove 2.2.1, and the other two groups of second rolling bodies 5 are arranged outside the two sides of the guide groove 2.2.1. The second rolling body 5 can make the movement of the support plate 2.2 more stable, so that the extended end of the support plate 2.2 can roll on the fixed platform 2.1.

[0047] It should be noted that a force applying handle 10 is further arranged on the support plate 2.2, which is arranged on the side of the support plate 2.2 close to the limiting table 2.1.1. The force applying handle 10 can be more convenient for the staff to control the support plate 2.2 on the sliding frame 2.
