What are the daily maintenance of the mold?

Primary maintenance of mold:

The primary maintenance of a mold refers to the routine maintenance of the mold by the operator during the production process. The main contents are cleaning, lubrication and inspection.

A, mold maintenance:

1., the mold should be cleaned before and after the surface of the mold, to ensure that the mold mounting surface and press work table without compression, damage to the mold in the production of the upper and lower mounting surface parallelism;

  1. after the mold is installed, the mold will be opened, the parts of the mold will be wiped clean, especially the guiding mechanism. For the surface of the mold, the shape of the surface should be wiped clean, in order to ensure the quality of the parts;
  2. lubricate the sliding parts of the die and grease the sliding parts;
  3. check the parts of the mold, especially the safety parts. Such as: safety side pin, safety screw, side fender, punching waste Road, etc..

B, maintenance in production:

  1. production of regular parts of the corresponding mold oil. Such as: drawing die of the press ring and fillet; trimming die edge parts; flanging, knife parts, etc.;
  2. clean scrap holes on trimming hole die regularly.

C, after production maintenance:

  1. after the end of production, the mold should be fully examined;
  2. clean the mold thoroughly to ensure the cleanliness of the mold;
  3. clean the waste material in the mold to ensure that there is no waste material in the waste bin;

4., the use of the state of the mold and the use of the situation truthfully feedback to the "use of mold work subpoenas".

Two stage maintenance of mould:

The two stage maintenance refers to the regular and systematic maintenance of the mold according to the technical status and complexity of the mold. This maintenance work is done by mould maintenance personnel and records are maintained according to maintenance. The following describes the requirements and methods for different parts:

A, drawing die, punch, die:

Punch and die drawing die the main problems and the galling brineling polishing maintenance mainly on die fillet picking parts. If there is a pressure pit, the mold should be repaired and welded, and then repaired;

B, guide parts (guide pillar, guide sleeve and guide plate, etc.):

Mold will appear in the work of scratch marks and so on. The main causes are lubrication dirty and guiding gap. When the guide parts produce pull marks, they should be removed by polishing with the stones;

C and trim edges:

In the process of using the die, the edge of the blade is prone to collapse and the edge of the blade collapses. At this time, the parts damaged by the die should be repaired and repaired;

D, spring and other elastic parts:

In the process of use, the spring is one of the most easily damaged parts of the mold, usually fracture and deformation. The approach is to replace, but the replacement process must pay attention to the spring of the specification and model of spring specifications with color, diameter and length of three, only three are in the same circumstances can change;

E, punch, punch:

Most of the punch and punch used in the die are made of standard parts, and the die is prone to break, bend and bite in the process of using the die. Damage to punches and covers is usually replaced by parts of the same specifications. The parameters of the punch mainly include the work part size, the installation part size, the length, size and so on;

F, fastening parts:

Check whether the fastening parts are loose or damaged. The idea is to replace parts of the same size;

G, press and discharge parts:

Pressing parts such as pressure plate, rubber, unloading parts such as unloading, pneumatic lifting device etc.. During maintenance, check the assembly relation of each part for damage and repair the damaged parts. Check whether there is air leakage or not, and take measures to the specific situation. If the trachea is damaged, replace.
