。In order to change the outer diameter and coating thickness of thin materials such as electric wires and cables that are to be coated with resin in an extruder, the nipple and die of the extruder head must be completely replaced. The work of replacing the nipple and die needs to be done in a short time, even though the head is hot, because it has to be done before the resin cools and taters. In the conventional technology, the head body is divided into two parts. It can be opened and closed freely, and the nipple and die were replaced with the main body of the head open. However, with this conventional technology, even if you want to change the wire thickness to the same 1, you cannot change it without cutting the wire, and the nipple and die are made in a narrow space, so it cannot be done in a short time. There was a risk of burns.The purpose of the present invention is to provide extrusion technology that allows the nipple and die to be separated from the head block and replaced in a wide space in a short time, and that eliminates the need to cut the wire during replacement. The purpose of the present invention is to provide a machine nipple and die changing device.

As shown in Figure 1, the system consists of nine hydraulic cylinders 62 installed between bases, the piston rond of this hydraulic cylinder 52 is connected to a movable base, and the upper end of this movable base is connected to the die holder 16. Pivotally supported movable rod 56,
56' is fixedly attached, and the hydraulic cylinder of the die holder opening/closing means is attached to this movable bracket. Therefore, when the piston of the hydraulic cylinder 52 extends,
The die holder 16 rises together with the die holder opening/closing means until the cartridge 18 comes into close contact with the head block 14 (see FIGS. 1 to 3), and when the piston of the hydraulic cylinder 52 contracts, the die holder 1
6, the cartridge 18 descends together with the die holder opening/closing means 38 line to the replacement position where the cartridge 18 is retreated from the semicircular recess 14a of the head block 140 (see Figures 4 and 5). In addition, the support rod 12 is fixed between the bases, and the movable rods 56, 56' have guide blocks 58, 58' which are guided along the support rods.
