The mold 11 can be transferred from the injection station to the mold opening and closing device 14 through the sliding platform 122 by the pushing oil cylinder 121. By arranging the mold station 1 and the mold opening and closing device 14 at the same height and using the same pushing oil cylinder 121, the mold 11 can be simultaneously sent into and out of the injection station and into the mold opening and closing device 14, thereby realizing injection molding and mold closing of the mold 11, respectively. This design saves device cost, reduces the occupied space, and facilitates subsequent maintenance.

[0039] The taking-out device 13 is connected with the mold opening and closing device 14 and can transfer the color separation plate 112 outward or convey the color separation plate 112 inward, and the taking-out device 13 comprises a conveying mechanism 131 and a separating mechanism 132, the conveying mechanism 131 is connected with the color separation plate 112, the color separation plate 112 is arranged on the conveying mechanism 131 and is driven by the conveying mechanism 131 to move out of or into the upper mold 111 and the lower mold 113, and the separating mechanism 132 is arranged between the upper mold 111 and the color separation plate 112 and drives the color separation plate 112 to separate from the upper mold 111 and the lower mold 113 respectively after injection molding in the mold closing state.

[0040] The conveying mechanism 131 comprises a slide 1311, a sliding seat 1312 and a driving assembly 1313, the slide 1311 is arranged in a horizontal direction on both sides of the mold station 1, the sliding seat 1312 is movably arranged in the slide 1311, and the color separation plate 112 is arranged on the two sliding seats 1312, the driving assembly 1313 is arranged on the slide 1311 and connected with the sliding seat 1312 and drives the sliding seat 1312 to move, the color separation plate 112 is arranged on the sliding seat 1312, the color separation plate 112 can be quickly placed and taken out at the mold opening and closing device 14 or the injection station, and the efficiency of the mold 11 opening and closing and the efficiency of injection molding and vulcanizing the sole are further improved. Specifically, the slide 1311 is inwardly recessed to form a groove 1314 on the opposite surface, the sliding seat 1312 is movably arranged in the groove 1314, the sliding seat 1312 is formed with a rack 1315 in the length direction of the sliding seat 1312 at the bottom, the driving assembly 1313 comprises a driving gear which can engage with the rack 1315 and a servo motor which drives the driving gear to rotate, the servo motor is precisely geared, the accuracy of the movement of the color separation plate 112 is ensured, and the color separation plate 112 can always be aligned with the upper mold 111 and the lower mold 113. Further, the sliding seat 1312 is provided with a bearing which can be clamped in the groove 1314, the friction between the sliding seat 1312 and the groove is reduced, and the moving efficiency of the sliding seat 1312 is improved.

[0041] The separating mechanism 132 further comprises a lifting cylinder 1321 and a separating cylinder 1322.

Specifically, the upper mold 111 extends outward to form a limiting column 1323 at both sides, and the top surface of the slide 1311 is formed with a top pressing plate 1324 opposite to the limiting column 1323. When the slide 1311 ascends, the top pressing plate 1324 contacts with the limiting column 1323 and clamps the upper mold 111 upward. Under the action of the lifting mechanism, when the color separation plate 112 separates, the top pressing plate 1324 abuts against the limiting column 1323 at both sides of the upper mold 111, and then the color separation plate 112 is pushed downward by the separating cylinder 1322 to separate the color separation plate 112 from the upper mold 111, so as to avoid the material overflow caused by the separation of the upper mold 111 and the injection hole connected with the upper mold 111 due to the adhesion of the material. Specifically, the color separation plate 112 extends outward to form a clamping rod 1325 at both sides opposite to the separating cylinder 1322.

The lifting frame 142 is arranged on the support 141 in a lifting manner and can be fixedly connected with the upper mold 111. The opening cylinder 143 is vertically arranged on the support 141 and connected with the lifting frame 142 to drive the lifting frame 142 to move upward to open the mold 11 or to move downward to close the mold 11. The color separation plate 112 is input and output by the conveying mechanism 131, which is used for separating the upper mold 111 from the lower mold 113 during injection molding, facilitating the production of a double-color shoe sole, and then the color separation plate 112 is withdrawn to vulcanize the shoe sole in the upper mold 111 and the lower mold 113. At the same time, the separating structure is used for auxiliary separation, so as to avoid the overflow of the material caused by the separation of the color separation plate 112 from the upper mold 111 or the separation of the mold 11 from the feeding port due to the adhesion of the material.

[0043] The injection gun 2 is arranged above the mold station 1 and connected with the mold 11 to inject the material inward.

[0044] The hydraulic pump station 3 is connected with the injection gun 2 to provide injection power for the injection gun 2.

[0045] The electric control system 4 is connected with each component and controls the operation of each component.

[0046] Embodiment Two:

[0047] The difference between this embodiment and the first embodiment is that only the mold station 1 exists without the conveying device 12 and the mold opening and closing device 14 (for example,Figure 4 When the mold 11 is closed, the lower mold 113 is placed on the clamping cylinder 15, and the upper mold 111 is fixed below the injection gun 2, the lower mold 113 is driven by the clamping cylinder 15 to move upward, and the color separation plate 112 is driven to move upward to perform clamping, and at the same time, the injection of the material in the upper mold 111 is directly completed.

[0048] When the device works, the lower mold 113 is placed on the support 141 of the mold opening and closing device, the upper mold 111 is placed on the lifting frame 142 of the mold opening and closing device 14, the bottom material is filled into the lower mold 113, the height position of the slide 1311 is adjusted by the lifting mechanism, the color separation plate 112 is conveyed from outside the mold station 1 to the mold opening and closing device 14 and located between the lower mold 113 and the upper mold 111 by driving the sliding seat 1312 by the driving assembly 1313, then the color separation plate 112 is driven to fall into the lower mold 113 by the lifting cylinder 1321, and the sliding seat 1312 is driven to move out of the mold station 1 by the driving assembly 1313. When the clamping cylinder 143 drives the lifting frame 142 to descend, the mold 11 is closed. The mold 11 is pushed into the mold station 1 by the pushing cylinder 121 through the sliding platform 122 and located above the clamping cylinder 15, the clamping cylinder 15 is lifted to drive the upper mold 111 to move upward and connect with the injection gun 2, and another color material is injected into the upper mold 111 by the injection gun 2. Then the lifting cylinder 1321 drives the slide 1311 to move upward, and the pressing plate 1324 on the slide 1311 is pressed upward against the upper mold 111, the color separation plate 112 is separated from the upper mold 111 by driving the separation cylinder 1322 to push downward, and the clamping cylinder 15 moves downward. Since the color separation plate 112 is arranged on the sliding seat 1312, the lower mold 113 continues to move downward, and the color separation plate 112 is separated from the lower mold 113 by the limiting of the sliding seat 1312. At this time, the color separation plate 112 is transferred to outside the mold station 1 by the taking device 13, the clamping cylinder 15 recombines the upper mold 111 and the lower mold 113 to vulcanize. After vulcanization, the mold 11 is pushed to the mold opening and closing device 14 by the pushing cylinder 121 through the sliding platform 122, and the upper mold 111 is lifted by the lifting frame 142 driven by the clamping cylinder 143 to open the mold and take out the product. The device has high automation, and the mold 11 is conveyed, and the color separation plate 112 is installed and removed without manual operation, which greatly improves the production efficiency and has high practicability.

[0049] The above is only a preferred embodiment of the present application, and cannot limit the scope of the present application.
