[0023] It consists of Figures 1 - 3 As shown, the present invention includes the body 1 of the molding machine and the rotatable rotating disk 2 located on the upper side of the body 1 of the molding machine. In order to facilitate the picking and placing of workpieces, a station bracket 3 is symmetrically arranged on the front and rear sides of the upper side of the rotating disk 2. A fixed bracket 4 is fixedly connected to the upper side of the rotating disk 2. A movable frame 5 that can move back and forth is provided on the upper side of the fixed bracket 4. Longitudinal connecting frames 6 are provided on the front and rear sides of the movable frame 5. A lower pressing plate 7 that can move up and down is provided on the lower side of each longitudinal connecting frame 6;

[0024] It should be further noted that the longitudinal connecting frame 6 is connected to the movable frame 5 by bolts, and a plurality of bolt connection holes are provided on the movable frame 5, so that the longitudinal connecting frame 6 can move back and forth relative to the movable frame 5, and thus can adapt to the processing of the handle impeller with different diameters;

[0025] During use, the handle impeller to be processed can be placed on the upper side of the rear station bracket 3. At this time, the rear lower pressing plate 7 is in a high position, and the staff can freely place the workpiece on the upper side of the rear station bracket 3. After the workpiece is placed, the rotating disk 2 will rotate, thereby driving each station bracket 3 and the lower pressing plate 7 to rotate together. Move the rear station bracket 3 to the front side. After the station movement is in place, the lower pressing plate 7 on the upper side of the workpiece will move downward to press the workpiece, and then the insert processing of the workpiece can be carried out. During the insert processing, the station bracket 3 will drive the workpiece to rotate to uniformly process the workpiece.

[0026] Furthermore, it consists ofFigures 1 - 3 Given that, in order to achieve better workpiece processing effects, a transverse frame 8 is fixedly connected to the lower side of the rotating disk 2.

[0027] During use, after starting the first motor 9, the workpiece bracket can be driven to rotate, thereby uniformly processing the circumference of the workpiece.

[0028] Furthermore, Figures 1 - 3 Given that, in order to achieve good workpiece positioning effects, the station bracket 3 includes a rotating frame 10 and a positioning frame 11. A ring-shaped protrusion 12 is provided in the middle of the rotating frame 10. The positioning frame 11 is located above the rotating frame 10.

A double-acting cylinder 17 is provided on the upper side of the fixed bracket 4. The double-acting cylinder 17 is a prior art, such as a double-shaft cylinder of model DXWM, which will not be described in detail here. The moving frame 5 is fixedly connected to the output shaft of the double-acting cylinder 17;

[0032] During use, by starting the double-acting cylinder 17, the moving frame 5 can be driven to move back and forth.

[0033] Furthermore, Figures 1 - 3 Given that, in order to press workpieces at different heights, a longitudinal cylinder 18 is fixedly connected to the middle of each longitudinal connecting frame 6. The output end of the longitudinal cylinder 18 is fixedly connected to a height adjustment mechanism 19.

[0034] Further, as shown by Figures 1 - 3 Figure 4, the height adjusting mechanism 19 includes a fixed shaft 20 fixedly connected to the output end of the longitudinal cylinder 18. An adjusting sleeve 21 is threadedly sleeved on the outer side of the lower part of the fixed end. The upper side of each lower pressing plate 7 is threadedly connected to the adjusting sleeve 21;

[0035] During use, by rotating the adjusting sleeve 21, the overall height of the height adjusting mechanism 19 can be adjusted, thereby realizing the adjustment of the height of the lower pressing plate 7, so that the lower pressing plate 7 can press workpieces of different heights after moving downward.

[0036] Further, as shown by Figures 1 - 3 Figure 5, in order to achieve a better pressing effect, a frustum protrusion 22 is fixedly connected to the lower side of the lower pressing plate 7.

The corresponding workpiece is being processed under pressing. The staff can freely place the workpiece on the upper side of the station bracket 3 at the rear side. When placing the workpiece, the positioning frame 11 can be picked up, and then the workpiece is placed on the upper side of the rotating frame 10. The annular protrusion 12 is used for longitudinally supporting the workpiece. Then, the positioning pin 15 is placed above the workpiece to make the circular block 13 cooperate with the circular groove 14. After the workpiece is placed, the turntable 2 will rotate 180° driven by the second motor 23, thereby driving each station bracket 3 and the lower pressing plate 7 to rotate together, moving the station bracket 3 at the rear side to the front side. At this time, the processed workpiece is close to the staff and at the operation end of the staff. Then, the longitudinal cylinder 18 at the end close to the staff will drive the lower pressing block to move upward to disengage from the pressed cooperation with the processed workpiece. The double-acting cylinder 17 will drive the moving frame 5 to move forward (away from the staff), so that the lower pressing block at the front side moves to the upper side of the unprocessed workpiece. Then, the longitudinal cylinder 18 on the upper side of the unprocessed workpiece drives the lower pressing block to move downward to complete the pressing of the workpiece. During the processing of the workpiece at the front side, the staff can take down the processed workpiece and place the next unprocessed workpiece using the above method to complete the cycle of workpiece picking, placing and processing.
