[0044] The present application is further described below with a specific workflow.

[0045] Step 1: open the mold station 2 on the unloading station 15, and place the bottom mold 22 on the mold station 2 on the unloading station 15 manually or by automatic manipulators and other equipment; then the disc 12 rotates, and the mold station 2 is transferred from the unloading station 15 to the second conversion station 18.

[0046] Step 2: At the second conversion station 18, the flip frame 24 on the mold station 2 is flipped to convert the auxiliary mold 26 into the main mold 25, and the main mold 25 is driven downward by the lifting cylinder 281 to close the bottom mold 22;

[0047] Step 3, the disc 12 rotates again, so that the mold station 2 enters the main mold injection station 13, and the main mold injection device 3 corresponds to the mold station 2 and injects the raw material into the main mold 25 to complete the first coloring of the bottom 22;

[0048] Step 4, the disc 12 rotates again, and the mold station 2 enters the first conversion station 16. At the first conversion station 16, the flip frame 24 on the mold station 2 flips, so that the main mold 25 is converted into the auxiliary mold 26 and the auxiliary mold 26 is driven by the lifting cylinder 281 to move downward to close the bottom mold 22;

[0049] Step 5, the disc 12 rotates again, so that the mold station 2 enters the auxiliary mold injection station 14, and the auxiliary mold injection device 4 corresponds to the mold station and injects the raw material into the auxiliary mold 26 to complete the second coloring of the bottom mold 22;

[0050] In step six, the disc 12 rotates again, and the mold station 2 enters a plurality of cooling stations 17, so that the bottom mold 22 has sufficient time to cool down; the disc 12 rotates again, and the mold station 2 comes to the unloading station 15 again, and the mold station 2 on the unloading station 15 is opened, and the product in the mold station 2 is taken out manually or by automatic manipulators and other equipment to realize two-color fully automatic injection molding.

[0051] Among them, since multiple mold stations 2 are equidistantly distributed on the disc 12, the unloading station 15, the second conversion station 18, the main mold injection station 13, the first conversion station 16, the auxiliary mold injection station 14 and the cooling station 17 are carried out simultaneously, realizing uninterrupted cyclic operation and improving work efficiency.

[0052] When the main mold 25 and the auxiliary mold 26 of the mold station 2 are switched, the flipping cylinder 27 is started to flip the flip frame 24 90°, and the positions of the main mold 25 and the auxiliary mold 26 are switched, so that the auxiliary mold 26 on the flip frame 24 is horizontally opposite to the bottom mold 2 on the mold support plate 21; the steps for converting the auxiliary mold 26 to the main mold 25 are the same.

[0053] In summary, with the help of the above technical solution of the utility model, through the cooperation between the workbench 1, the multiple mold stations 2 sequentially arranged on the main mold injection station 13, the auxiliary mold injection station 14, the unloading station 15, the first conversion station 16, the cooling station 17 and the second conversion station 18, the main mold injection device 3 arranged on the side of the workbench 1, and the auxiliary mold injection device 4 arranged on the side of the workbench 1, the main mold 25 and the auxiliary mold 26 can be switched back and forth, and the main mold injection device 3 and the auxiliary mold injection device 4 can be cooperated to color the bottom mold 22 twice, thereby obtaining a two-color product, and realizing the two-color fully automatic injection molding process. In addition, by setting two molding devices 5 at intervals on the sides of the workbench 1, the clamping efficiency of the mold station 2 can be improved, which is beneficial to the coloring of the bottom mold 22; in addition, by setting a scraper plate 212 on the mold support plate 21 opposite to the injection nozzle 35, the raw material on the injection nozzle 35 can be scraped off, thereby ensuring that the contact surface between the injection nozzle 35 and the injection port of the mold is not offset, so that the raw material can be easily injected into the mold; in addition, by setting a shooting gun lifting mechanism 33 between the injection machine frame 31 and the shooting gun 32, the lifting height of the shooting gun 32 can be adjusted, and at the same time, the lifting process of the shooting gun 32 can be ensured to be smooth.

[0054] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of application of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
