ISO 6751 pdf download Tools for moulding — Ejector pins with cylindrical head
1 Scope
This International Standard specifies the dimensions and tolerances, in millimetres, of ejector pins with cylindrical head which are used in compression and injection moulds and in die casting dies.
It also gives material guidelines and hardness requirements, and specifies the designation of ejector pins with cylindrical head.
Flat ejector pins are specified in ISO 8693 and shouldered ejector pins are specified in ISO 8694.
2 Dimensions
The dimensions of ejector pins shall be in accordance with the indications of Figure 1 and Tables 1 and 2.
Surface roughness values in micrometres
3 Material and hardness
Ejector pins with cylindrical head shall be made of hot worked steel or alloyed cold worked steel. The hardness of the shaft and head shall conform to the indications of Table 3.
4 Designation
Ejector pins with cylindrical head according to this International Standard shall be designated by:
a) “ejector pin with cylindrical head”;
b) reference to this International Standard, i.e. ISO 6751;
c) ejector pin diameter, D 1 , in millimetres;
d) ejector pin length, L, in millimetres;
e) ejector pin material.
EXAMPLE The designation for an ejector pin with cylindrical head of diameter D 1 = 2 mm, of length L = 100 mm and of hot worked steel is as follows:
Ejector pin with cylindrical head ISO 6751 – 2 – 100 – Hot worked steel
