[0020] The mold support plate 1 comprises a fixing plate 11 arranged on the mold support plate 1 for mounting the bottom mold 2 .

[0021] The bottom mold 2 is arranged on the mold supporting plate 1 .

[0022] The support plate 3 is movably disposed above the bottom mold 2 ; specifically, a mounting seat 31 for mounting the turning cylinder 7 is disposed on the support plate 3 .

[0023] The flip frame 4 is flippably arranged on the support plate 3; the main mold 5 and the auxiliary mold 6 are arranged at 90 degrees on the flip frame 4; specifically, the flip frame 4 includes a flip frame body 41 rotatably arranged on the support plate 3, a connecting block 42 arranged on the side of the flip frame body 41 and connected to the flip cylinder 7, a first mounting plate 43 arranged on the flip frame body 41 for mounting the main mold 5, and a second mounting plate 44 arranged on the flip frame body 41 at 90 degrees to the first mounting plate 43 for mounting the auxiliary mold 6; further, the flip frame body 41 includes an L-shaped arrangement, on which a first connecting section 45 connected to the first mounting plate 43 and a second connecting section 46 connected to the second mounting plate 44 are respectively arranged.

[0024] The turning cylinder 7 is arranged on the supporting plate 3 and connected to the turning frame 4 .

[0025] The lifting mechanism 8 is arranged on the mold support plate 1 and is connected to and drives the support plate 3 to move up and down, including two lifting cylinders 81 arranged at intervals on the mold support plate 1 and connected to the support plate 3. The two lifting cylinders 81 can drive the support plate 3 away from or close to the bottom mold 2; specifically, the lifting mechanism 8 also includes a guide member 82 arranged between the mold support plate 1 and the support plate 3, and the guide member 82 includes a plurality of guide rods 83 arranged at intervals on the mold support plate 1 and extending in the vertical direction and a guide block 84 that can be moved up and down and is arranged on the guide rods 83 and connected to the support plate 3; further, the lifting mechanism 8 also includes two positioning cylinders 85 arranged on the mold support plate 1 and located on both sides of the fixed plate 11 respectively; the position of the first mounting plate 43 or the second mounting plate 44 can be fixed by the two positioning cylinders 85.

[0026] The present application is further described below with reference to a specific process.

[0027] Step 1: Install the mold, install the main mold 5 on the first mounting plate 43, the auxiliary mold 6 on the second mounting plate 44, and fix the bottom mold 2 on the fixing plate 11;

[0028] Step 2: The main mold 5 is closed. At this time, the main mold 5 on the first mounting plate 43 is horizontally opposite to the bottom mold 2 on the fixed plate 11. The positioning cylinder 85 is extended to ensure that the position of the first mounting plate 43 is not offset. The two lifting cylinders 81 are started to simultaneously retract the support plate 3 downward, so that the main mold 5 on the first mounting plate 43 overlaps with the bottom mold 2. Then, the main mold injection action is performed to complete the first coloring of the bottom mold 2.

[0029] Step 3: Switch the main mold 5 and the auxiliary mold 6. After the injection action of the main mold is completed, start the two lifting cylinders 81, so that the two lifting cylinders 81 simultaneously lift the support plate 3 upward to the highest point of the guide rod 83, and the main mold 5 on the first mounting plate 43 is completely separated from the bottom mold 2. At this time, the positioning cylinder 85 retracts to make the first mounting plate 43 movable, and then start the flip cylinder 7 to flip the flip frame 4 90°, switch the position of the first mounting plate 43 and the second mounting plate 44, so that the auxiliary mold 6 on the second mounting plate 44 is horizontally opposite to the bottom mold 2 on the fixed plate 11; the steps for converting the auxiliary mold 6 to the main mold 5 are the same;

[0030] Step 4: The auxiliary mold 6 is closed. At this time, the auxiliary mold 6 on the second mounting plate 44 is horizontally opposite to the bottom mold 2 on the fixed plate 11. The positioning cylinder 85 is extended to ensure that the position of the second mounting plate 44 is not offset. The two lifting cylinders 81 are started to make the two lifting cylinders 81 simultaneously retract the support plate 3 downward to make the auxiliary mold 6 on the second mounting plate 44 overlap with the bottom mold 2, and then the auxiliary mold injection action is performed to complete the second coloring of the bottom mold 2.

[0031] In summary, with the help of the above-mentioned technical scheme of the utility model, the specific structure of the mold turning device is limited, so that the main mold 5 and the auxiliary mold 6 on the turning frame 4 can be respectively molded with the bottom mold 2 under the action of the turning cylinder 7 and the lifting mechanism 8, and the bottom mold 2 can be colored twice, thereby obtaining a two-color product.

[0032] 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.
