Plastic injection mold two level maintenance

Secondary refers to the maintenance of the custom plastic mold die for the periodic maintenance of the system according to the state of the art and the complexity of the mold making. This maintenance work is completed by mold repair personnel, and make records in accordance with the maintenance situation. The following describes the different parts of the other security requirements and methods:

A, drawing die punch die:

Convex drawing die, die major problems is the pressure pit nap and type face, the main part of the fillet nap when mold polishing and maintenance. If there is pressure on the pit to die repair welding, and then repair shun;

B, guiding parts (guide post, guide sleeve and the guide plate, etc.):

Pull mold marks and other phenomena occur at work. The main causes of dirty lubricating oil and orientation bias and so the gap. When the guide parts produced pull marks, taking pushed oil stone polished smooth way to eliminate;

C, trimming blade:

Mold in the course of the blade section prone to chipping and edge collapse phenomenon, this time to the damaged parts of the mold repair welding;

D, spring or other elastic parts:

In use, the spring is one of the most easily damaged parts mold, usually a fracture and deformation phenomena. The approach taken is to be replaced, but the replacement process must pay attention to the spring specifications and models, spring specifications by color, diameter and length of the three identified, the next three are the same, only in this case it can be replaced;

E, punch, punch sets:

Punch used on the plastic injection mold, punch sets most used standard parts, mold in the course of punch prone to break, bend and eating bad phenomenon, red sets are generally eating bad. Punch and punch sets are generally damaged replacement parts with the same specifications. The main parameters of the punch working portion size, the size of the mounting portion, the length dimensions, etc.;

F, fastening parts:

Check for loose fasteners, damage phenomenon. The approach taken is to find replacement parts for the same size;

G, pressure loading and unloading parts:

Binder components such as pressure plate, distinctions of plastic, etc., unloading parts such as the stripper plate, pneumatic ejector devices. Inspection and maintenance of the parts of the assembly for damage, some damage to be repaired. Check pneumatic ejector without leakage phenomenon, and to take measures to the specific situation. Replace damaged such as the trachea and the like.
