Shandong mould assembly line standard specification模具装配线后，应超过以下关键标准:
After die assembly line, the following key standards shall be exceeded:
(1) The assembly line of standard parts shall be reliable. The screw length of the anchor bolt shall not be less than the diameter of the anchor bolt when connecting the cast iron, and shall not be less than 1.5 times of the diameter of the anchor bolt when connecting the cast iron; the matching length of the pin and each component shall be more than 1.5 times of the diameter of the pin; the inner hole of the anchor bolt and the pin shall not expose the surface of the upper and lower mold bases and other parts.
（2） The blanking hole or feed groove shall be flat to ensure that the production or waste can be discharged at will.
(3) Exchange standards. The screw tightening and the precise positioning of the pin hole between the two should be in good condition.
（4） The installation specification of the grinding tool of the press shall conform to the use regulations of the machine and equipment; the lifting parts shall be reliable.
(5) The abrasives are inspected according to the manufacturing standards, and the production meets the requirements of the design scheme.
(6) The accuracy of mold base conforms to the national industry standard (LF / t8050-1998 technical standard for metal mold base; LF / t8071-1997 precision inspection for metal mold base). The height width ratio of hardware mould shall meet the requirements of engineering drawing.
(7) The hardware mould of the assembly line shall be good, and the bottom mould shall be stable and reliable when it is dragged up and down along the locating pin.
(8) The gap between the die and the punch shall meet the requirements of the engineering drawing and be spread evenly. The work of mold base or cavity shall be arranged according to the requirements of technical standards.
(9) The accurate positioning and relative position of retaining equipment shall meet the requirements of engineering drawing. The distance between guide plates of the cold stamping die is the same as that of the engineering drawing; the guide rail surface shall be parallel to the axis of the feed bearing of the die; the guide plate is equipped with side pressing device, and the side pressing plate shall be easy to drag and work reliably.
(12) The relative part reversing and lifting equipment shall conform to the design scheme, and the redundant width shall meet the allowable requirements, and shall not be placed on the title face without deflection and unilateral deflection, so as to ensure that the production or waste can be deleted immediately and successfully.
