[0002] During the use of the mold, it is often maintained and serviced. If it is damaged, it needs to be repaired. During the repair, a large number of inserts and positioning pins must be removed. Part of the disassembly work requires the use of a pin puller, and the pin puller terminal used in conjunction with the pin puller is a key unit. The pin puller terminal is usually welded by two hexagon socket screws. The welding quality of the pin puller terminal directly affects its service life. However, the pin puller terminal welded without clamping has the following defects:
[0003] 1. The two hexagon socket screws are not concentric;
[0004] 2. During use, the force transmission is not in the same straight line, which is very laborious;
[0005] 3. When in use, the force is decomposed to other directions, which may easily damage the screw thread of the pin terminal, shorten its service life, and cause damage to the screw thread of the mold insert, affecting its disassembly. Summary of the invention

[0008] Furthermore, the first shaft sleeve is slidably matched with the inner hole of the first mounting block, the second shaft sleeve is slidably matched with the inner hole of the second mounting block, and the first shaft sleeve is concentric with the second shaft sleeve.
[0009] Furthermore, the hexagon socket screw 2 is slidably matched with the inner hole of the sleeve 1, the hexagon socket screw 1 is slidably matched with the inner hole of the sleeve 2, and the hexagon socket screw 1 is concentric with the hexagon socket screw 2.
[0010] Furthermore, the mounting block 1 and the mounting block 2 are respectively fixed to the two ends of the base plate by means of hexagon socket screws 3, and the mounting block 1 and the mounting block 2 are both perpendicular to the base plate.

[0012] Furthermore, the inner holes of the shaft sleeve 1 and the shaft sleeve 2 are of various sizes and specifications that can meet the requirements of welding various types of pull pin terminals.
[0013] Compared with the prior art, when making a pull-out pin terminal, the utility model places a sleeve 1 in a mounting block 1, and places a hexagon socket screw 2 to be welded into a pull-out pin terminal in sleeve 1; sleeve 2 is placed in a mounting block 2, and a hexagon socket screw 1 to be welded into a pull-out pin terminal is placed in sleeve 2; at the same time, sleeve 1 and sleeve 2 are pushed inwards, so that the heads of hexagon socket screw 1 and hexagon socket screw 2 are in contact, and then the locking bolt 1 and the locking bolt 2 are tightened, so that the heads of hexagon socket screw 1 and hexagon socket screw 2 can be welded together. The utility model has a simple structure and low manufacturing cost, and can facilitate the welding of pull-out pin terminals, optimize and improve the welding quality of pull-out pin terminals, and greatly extend the service life of pull-out pin terminals and molds.
