The frame structure does not affect the clamping of the upper mold and the lower mold, and the upper mold and the lower mold are both located in the frame. The cavities of the upper mold and the lower mold are both open at the two ends, which does not affect the sliding of the workpiece in and out, and in the clamped state, the flanges at the two ends of the lightning arrester are outside the mold, and the cavity is closed through the flanges at the two ends of the lightning arrester and the external baffle.

[0029] The mold moving frame body of the embodiment is divided into two parts, a fixed frame 2 and a moving frame 3. The fixed frame 2 is placed on the mounting platform for fixing the lower mold 8 through the mounting plate 1. The mounting plate 1 has a total of four guide columns 6 at the four corners, which penetrate the mounting platform and extend downward, so that the fixed frame 2 and the lower mold 8 cannot move relatively in the horizontal direction, and the two planes can only move up and down. Below the four guide columns 6, a mold moving frame limiting base 10 is arranged. When the arrester is vulcanized, the upper and lower molds are opened, and the arrester moves downward in the lower mold 8 due to gravity, the mounting platform moves downward together with the hydraulic oil cylinder 9, the fixed frame 2 also moves downward on the mounting platform, when the four guide columns 6 contact the mold moving frame limiting base 10, the fixed frame 2 will stop moving downward, while the lower mold 8 and the mounting platform continue to move downward with the hydraulic oil cylinder 9, the lower mold 8 is separated from the fixed frame 2, the vulcanized arrester is lifted by the workpiece carrier 4 of the moving frame 3 and remains on the mold moving frame, and the mold opening action is completed.

The arrester on the moving frame 3 is manually pulled out, the arrester is moved out of the vulcanization mold area, and the mold moving action can be completed.

[0030] The vulcanized arrester is taken out, the arrester core is fixed on the workpiece carrier 4 of the moving frame 3, the moving frame 3 is manually pushed into the vulcanization mold area, and the moving frame 3 is pushed to the upper side of the lower mold 8. The lower mold 8 and the mounting platform are controlled to move upward, and when the mounting platform reaches the height of the fixed frame 2, the mold moving frame is lifted upward together, and the mold closing action is completed.

[0031] In the embodiment, the material rigidity of the mold moving frame is sufficient to support the weight of the finished arrester product. The inner side stop position of the moving frame should be matched with the arrester mold, otherwise the arrester may be damaged or the mold may be damaged. The arrester mold baffle on the moving frame should be matched with the mold. The lower limit of the moving frame and the lower limit of the lower mold are reasonably matched to complete the mold opening and closing.

[0032] With the device, the core placement and arrester mold opening operation outside the injection vulcanization machine mold can be smoothly realized. Meanwhile, the device is provided with an interface with the mold, and the arrester mold opening action can be realized together with the mold opening action without manual intervention, so that the arrester can be smoothly opened. Since the mold opening speed can be set on the vulcanization machine and matched with the device, the damage of the silicone rubber outer sleeve skirt in the mold opening process can be greatly reduced. The qualified rate and production efficiency of the vulcanization process are improved, and the risk of crushing and scalding of the operator is reduced.
