In addition, when the mold is opened, the motion direction of the flat slide block is limited by the smooth inclined rod, and the motion track of the flat slide block is limited by the smooth groove, so that the flat slide block moves away from the movable mold core in the smooth groove, and the positioning insert is drawn out from the positioning insert groove; utilize the motion direction of oblique slider of oblique slip down-tilting rod restriction, utilize oblique spout to inject the motion trail of oblique slider to make oblique slider deviate from the movable mould core in oblique spout and remove, take out the wire guide insert from wire guide insert groove, accomplish the die sinking, the die sinking easy operation is convenient. When the die is closed, a smooth inclined rod is utilized to apply pretightening force to the flat slide block, so that the positioning insert is inserted into the positioning insert groove; the inclined slide rod applies pretightening force to the inclined slide block to insert the wire guide hole insert into the wire guide hole insert groove, so that molten metal for die casting is prevented from entering the positioning insert groove and/or the wire guide hole insert groove through the die casting cavity and even entering the smooth groove and/or the inclined slide groove to block the flat slide block and/or the inclined slide block, and the service life of the die is prolonged. When the wool brush head is used for polishing the hole wall and the hole opening of the wire guide hole in the accessory blank, the contact residence time between the wool brush head and the accessory blank is controlled within 2 seconds, and metal residues adhered to the wool brush head can be prevented from scratching the accessory blank, particularly the wire guide hole of the accessory blank, when the wool brush head is contacted for a long time, so that the accessory blank can be prevented from being damaged and scrapped, and the production qualified rate of accessories of a textile machine is further improved. The wire guide is subjected to mirror surface extrusion polishing treatment, so that the hole wall and the hole opening of the wire guide can achieve a mirror surface effect, and the roughness of the hole wall and the hole opening of the wire guide can be ensured to meet the processing requirements.
