Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 One embodiment provided by this utility model:
[0022] A tool for installing and removing extruder cores includes an operating handle 1, a tool connecting rod 2, an auxiliary handle 3, and a tool head 4. The left end of the tool connecting rod 2 holds the operating handle 1, the auxiliary handle 3 is installed on the upper center side of the tool connecting rod 2, and the tool head 4 is threadedly connected to the right end of the tool connecting rod 2.
[0023] As a further feature of this utility model, the right end of the tool connecting rod 2 is provided with a tool rod connecting external thread 201, the left end of the tool connecting rod 2 is fixed with a clamping member 21, and the right end of the tool connecting rod 2 is evenly equipped with limit rings 22. The clamping member 21 includes a U-shaped block 211 and a fixed V-shaped clamping block 212. The inner rear wall of the U-shaped block 211 is fixed with the fixed V-shaped clamping block 212. A lead screw 213 is installed at the center of the fixed V-shaped clamping block 212. The front end of the lead screw 213 extends to the front side of the U-shaped block 211. The front end of the lead screw 213 is threaded with a lead cylinder 214. The rear end of the lead cylinder 214 is connected to a limit V-shaped clamping block 215. The fixed V-shaped clamping block 212 and the limit V-shaped clamping block 215 are used to clamp the operating handle 1 of different sizes.
[0024] Furthermore, the limiting ring 22 facilitates the installation of the auxiliary handle 3. The limiting ring 22 includes a fixing ring block 221 and a positioning block 222. The top of the fixing ring block 221 is embedded with the positioning block 222, and the center of the positioning block 222 has a threaded hole 223, which facilitates the installation of the auxiliary handle and makes it convenient for users to use.
[0025] Furthermore, a connecting plate 31 is fixedly provided at the bottom of the auxiliary handle 3, and a docking block 32 is fixedly provided on both sides of the connecting plate 31. A bolt 33 is provided in the center thread of the docking block 32, and the bottom side of the bolt 33 is screwed to the upper side of the limiting ring 22, which facilitates the user's operation and reduces damage to the mold core.
