[0034] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figures 1 to 5 As shown, the embodiment of the utility model provides a high-efficiency injection molding machine for manufacturing plastic toys, including an injection molding machine body 1, a material taking manipulator 2, a material unloading rack 3, a workpiece stacking fixture 4, a mobile material pushing mechanism 5, a lifting mechanism 6, a transfer carrier 7, a material unloading push cylinder 8 and a material unloading conveyor belt 9;

[0036] The unloading rack 3 is arranged at the side end of the injection molding machine body 1, and the workpiece stacking fixture 4 is arranged on the unloading rack 3. The injection molding machine body 1 is used to inject plastic material into plastic toys. The material picking robot 2 is arranged between the injection molding machine body 1 and the unloading rack 3, so as to clamp the plastic toys on the injection molding machine body 1 to the workpiece stacking fixture 4. The workpiece stacking fixture 4 is used to stack the plastic toys. The injection molding machine body 1 can inject the heated and melted plastic material into the mold, and form a plastic toy after cooling and solidification. The workpiece stacking fixture 4 can receive the plastic toys clamped by the material picking robot 2, and stack them, thereby providing preparation for subsequent transfer and unloading operations.

[0037] The transfer carrier 7 is arranged on the unloading rack 3 at the side end of the workpiece stacking fixture 4, and the lifting mechanism 6 is connected to the transfer carrier 7 to adjust the height of the transfer carrier 7. The mobile pushing mechanism 5 is arranged on the top of the unloading rack 3 and can be moved in the horizontal direction of the unloading rack 3 to push the plastic toys on the workpiece stacking fixture 4 to the transfer carrier 7; the lifting mechanism 6 can adjust the height of the transfer carrier 7. When the transfer carrier 7 is lifted to the same height as the workpiece stacking fixture 4, the mobile pushing mechanism 5 can push the stacked plastic toys on the workpiece stacking fixture 4 to the transfer carrier 7.

[0038] The unloading conveyor belt 9 is arranged at the side end of the unloading rack 3, and the unloading push cylinder 8 is arranged at one end of the unloading rack 3 away from the unloading conveyor belt 9, and its movable end is arranged toward the transfer carrier 7, so as to push the plastic toys on the transfer carrier 7 to the unloading conveyor belt 9 for unloading. The unloading push cylinder 8 is used to push the plastic toys to the unloading conveyor belt 9 to realize the smooth unloading of the plastic toys; and the unloading conveyor belt 9 receives and transmits the plastic toys to transfer them from the production line to the next process.

The Z-axis moving module 213 is connected to the X-axis moving module 211. The workpiece adsorption fixture 22 is arranged at the bottom of the Z-axis moving module 213 to adsorb or release plastic toys. Through the coordinated movement of the three-axis moving mechanism 21 and the adsorption and release function of the workpiece adsorption fixture 22, the material-retrieving manipulator 2 can remove the plastic toys from the injection molding machine body 1 and transfer them to the workpiece stacking fixture 4 for automatic stacking and placement.

[0040] like Figures 3 to 5 As shown, further, the workpiece stacking fixture 4 includes a fixed disk body 41 and a plurality of first guide rods 42; the fixed disk body 41 is provided with discharge holes 43 arranged in a vertical and horizontal matrix, and the plurality of first guide rods 42 are arranged along the circumferential direction of the discharge holes 43 to enclose a limiting channel 44 for limiting the placement of plastic toys. The limiting channel 44 can laterally limit the plastic toys to prevent the plastic toys from shifting during the stacking process. When multiple plastic toys are located in the same limiting channel 44 at the same time, the plastic toys placed front and back can be stacked under the push of the material picking robot 2; the first guide rod 42 is provided with a bending section 421 at the end close to the material picking robot 2, and the bending section 421 is used to guide the plastic toys to smoothly enter the limiting channel 44, thereby reducing the problem of misalignment or jamming of plastic toys during the stacking process.

[0041] like Figure 2 and Figure 3As shown, further, the movable pusher mechanism 5 includes a transverse moving component 51, a pusher frame 52 and a pusher rod 53. The transverse moving component 51 is arranged on the top of the lower material frame 3, and its movable end is connected to the pusher frame 52 to drive the pusher frame 52 to move toward or away from the workpiece stacking fixture 4. The pusher rod 53 is arranged on the pusher frame 52 to push the plastic toys stacked in the limiting channel 44 out of the discharge hole 43 to the transfer carrier 7. By controlling the movement of the transverse moving component 51, the position of the pusher frame 52 can be adjusted to accurately align with the plastic toys in the limiting channel 44. The pusher rod 53 can push the plastic toys along the limiting channel 44 toward the discharge hole 43 as the transverse moving component 51 moves, so as to push the plastic toys onto the transfer carrier 7. It should be noted that, in this embodiment, the lateral moving component 51 is a screw moving component driven by a motor, wherein the structure of the motor is not shown in the figure. However, as the lateral moving component 51 is a disclosed prior art, this embodiment will not elaborate on the specific structure of the lateral moving component 51.

[0042] like Figure 3 and Figure 4 As shown, further, the transfer carrier 7 includes a transverse plate 71 and a plurality of second guide rods 72, the transverse plate 71 is connected to the lifting mechanism 6, and the plurality of second guide rods 72 are arranged along the length direction of the transverse plate 71, and the second guide rods 72 are used to support the stacked plastic toys to be transferred, and the lifting mechanism 6 is used to adjust the height of the second guide rods 72 so that the second guide rods 72 are aligned with the position of the discharge hole 43, or aligned with the position of the unloading push cylinder 8. It should be noted that two second guide rods 72 can support the stacked plastic toys on one limiting channel 44.

[0043] like Figure 4 As shown, further, the lifting mechanism 6 includes a driving motor 61, a driving pulley 62, a driven pulley 63 and a transmission belt 64.

The transmission belt 64 is sleeved between the driving pulley 62 and the driven pulley 63, and is connected to the cross plate 71 through a clamping member 65. The driving motor 61 is connected to the driving pulley 62 to drive the driving pulley 62 to rotate. When the driving motor 61 is started, the power provided by it is transmitted to the driving pulley 62, causing the driving pulley 62 to rotate. Since the transmission belt 64 is sleeved between the driving pulley 62 and the driven pulley 63, the rotation of the driving pulley 62 will cause the movement of the transmission belt 64. The transmission belt 64 is connected to the cross plate 71 through a clamping member 65. Therefore, the movement of the transmission belt 64 will cause the cross plate 71 to move up and down, thereby achieving the height adjustment of the transfer carrier 7.

[0044] like Figure 2 and Figure 3 As shown, further, the movable end of the unloading push cylinder 8 is provided with a push baffle 81. When the second guide rod 72 is lifted to the same level as the push baffle 81 under the action of the lifting mechanism 6, the unloading push cylinder 8 is used to push the stacked plastic toys on the second guide rod 72 onto the unloading conveyor belt 9. It should be noted that the transfer carrier 7 has multiple rows of horizontally arranged second guide rods 72. A single push of the unloading push cylinder 8 can only push a single row of stacked plastic toys on the transfer carrier 7 outward onto the unloading conveyor belt 9, so as to avoid multiple rows of stacked plastic toys being pushed outward at the same time and falling on the unloading conveyor belt 9 to cause stacking dispersion.

[0045] The injection molding machine body 1 of the utility model can inject plastic materials into plastic toys, and the material taking manipulator 2 can clamp the plastic toys on the injection molding machine body 1 to the workpiece stacking fixture 4. The workpiece stacking fixture 4 has a limiting channel 44 arranged in a vertical and horizontal matrix, and the limiting channel 44 can laterally limit the plastic toys. When multiple plastic toys are located in the same limiting channel 44 at the same time, the plastic toys placed in the front and back can be stacked under the pushing action of the material taking manipulator 2. The lifting mechanism 6 can adjust the height of the transfer carrier 7. When the transfer carrier 7 is moved to the same height as the workpiece stacking fixture 4, the mobile pushing mechanism 5 can push the stacked plastic toys onto the transfer carrier 7 for transfer placement. When the second guide rod 72 of the transfer carrier 7 is moved to the same height as the unloading conveyor belt 9, the unloading pushing cylinder 8 can push the stacked plastic toys into the unloading conveyor belt 9 for unloading and conveying. The entire stacking and unloading process is automated, eliminating the tedious operation of manually stacking plastic toys, and greatly improving the unloading efficiency of the workpiece.

[0046] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
