[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a turning device for processing a rubber sheath, comprising:

[0029] A lifting frame assembly 1 installed inside the vulcanizing machine;

[0030] Two guide plates 2 are arranged side by side on the inner side of the lifting frame assembly 1, and the guide plates 2 are slidably matched with the lifting frame assembly 1, so as to facilitate the later movement of the mold core 5 located on the inner side of the lifting frame assembly 1 to the outside;

[0031] The rotating shaft 3 is rotatably mounted at one end between the two guide plates 2, so as to facilitate adjustment of the positions of the mold cores 5 on both sides of the rotating shaft 3, so that when one group of mold cores 5 is in the vulcanization process, the other group of mold cores 5 is located outside the vulcanizer for demoulding, thereby reducing the working time of the vulcanizer occupied when manually demoulding one group of mold cores 5;

[0032] Two crossbeams 4 are symmetrically arranged on both sides of the rotating shaft 3, and one end of the crossbeam 4 has a connecting component 6 detachably connected to the rotating shaft 3, which is convenient for installing two sets of mold cores 5. The mold core 5 is detachably installed on the side wall of the crossbeam 4.

[0033] Preferably, the lifting frame assembly 1 includes a side plate 101, a limit baffle 102 and a positioning plate 103. The two side plates 101 are arranged side by side and connected to the vulcanizer through two groups of side plates 101. One end of the side plate 101 has a limit baffle 102 fixed to the other side plate 101, and the other end of the side plate 101 is provided with a positioning plate 103, which is convenient for limiting the moving position of the guide plate 2. After the movement, the position of the crossbeam 4 is positioned by the positioning plate 103.

[0034] Preferably, two groups of rolling bearings 104 are arranged side by side on one side wall of the side plate 101, and a protrusion 201 cooperating with the two groups of rolling bearings 104 is arranged on one side wall of the guide plate 2, so as to reduce the resistance of the push-pull guide plate 2 by rolling, thereby improving the convenience of adjusting, moving and flipping the two beams 4 in the later stage.

[0035] Preferably, a positioning groove 105 is provided inside the positioning plate 103, and a positioning column head 401 matching the positioning groove 105 is fixed to one end of the crossbeam 4, so as to facilitate positioning of the crossbeam 4, so that the mold core 5 is in the correct position during the vulcanization process.

[0036] Preferably, a limiting nut 202 is connected to one side surface of the guide plate 2 by bolts, and one end of the guide plate 2 protrudes downward to form a bump, which is convenient for limiting the position of the guide plate 2 moving toward the outside of the lifting frame assembly 1.

[0037] Preferably, a bearing seat is provided at one end of one side wall of the guide plate 2, and a connecting bearing 203 matching with the rotating shaft 3 is provided inside the bearing seat to facilitate better flipping action.

[0038] Preferably, a connecting block 402 is fixed at one end of the crossbeam 4, and the connecting block 402 and the connecting assembly 6 are fixed by bolts and mounting grooves, so as to facilitate the disassembly and maintenance of the crossbeam 4 at a later stage.

[0039] Preferably, an assembly groove 403 is provided on the side wall of the beam 4, a connecting column 501 corresponding to the assembly groove 403 is provided at one end of the core mold 5, and a mounting hole 502 is provided on the inner side of the connecting column 501, and a positioning plane is provided on the lower surface of the connecting column 501 to facilitate the subsequent separate disassembly and maintenance of the core mold 5, and through the cooperation between the positioning plane on the lower surface of the connecting column 501 and the beam 4, the stress on the fixing bolts after the connecting column 501 and the beam 4 are connected through the mounting hole 502 and the fixing bolts is reduced.

[0040] Preferably, a plurality of mold cores 5 are evenly distributed along the long side of the crossbeam 4 .

[0041] like Figure 6 As shown, the existing frame-lifting demoulding process is: when demoulding, the mold core is lifted by the lifting frame, and the sheath product on the human side is taken away first, and then the crossbeam drives the mold core to rotate 180 degrees with the rotating axis as the rotation center to take away the sheath product at the rear. After all the sheath products are taken away, the mold core is rotated back to the original position to continue production.

[0042] A method for processing a turning device for processing a rubber sheath comprises the following steps:

[0043] Step A: After vulcanization, the crossbeam 4 is pulled toward the side away from the lifting frame assembly 1. At this time, the crossbeam 4 drives the guide plate 2 to move through the connecting assembly 6. The guide plate 2 and the side plate 101 rotate through the rolling bearing 104 for transmission;

[0044] Step B: After the other crossbeam 4 is separated from the upper mold and the lower mold of the vulcanizer, the crossbeam 4 is turned toward the side of the lifting frame assembly 1. At this time, the connecting assembly 6 and the guide plate 2 are rotated through the rotating shaft 3 and the connecting bearing 203 until they are turned 180 degrees, and the positions of the two crossbeams 4 are exchanged;

[0045] Step C: Push another crossbeam 4 to move toward the side of the lifting frame assembly 1, so that the guide plate 2 slides and resets. At this time, the positioning column head 401 at one end of the crossbeam 4 extends into the inner side of the positioning groove 105. After the upper mold and the lower mold are combined, the vulcanization process is performed through another crossbeam 4, and the sulfide on the crossbeam 4 can be demoulded at the same time;

[0046] Step D: After damage occurs, the connecting bolts between the crossbeam 4 and the mold core 5 can be screwed and one of the mold cores 5 can be disassembled and replaced separately.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
