Maintenance procedure of mold

Maintenance of the mold is divided into a primary maintenance level and second maintenance  level. Mold maintenance level refers to the operation of the mold and daily maintenance in production, the main content is clear cleaning, lubrication and inspection. Mold maintenance of two refers to the regular system of the mold according to the technical state of mold and complexity of maintenance.

Mold maintenance level

1, the maintenance of die

A, surface cleaning,ensure mold mounting surface and press working table not compressed and mould in production on the parallel degree of surface mounting.

B, die installed after the mold is opened, the various parts of mold cleaning clean, especially the guiding mechanism,the surface mold, the surface clean up, to ensure the quality of the product. For the lubrication of the slidingmold parts, coated with grease. The part of moldinspection, especially the safety components. Such as:safety pin, safe screw, a side guard plate, punching wasteetc..

2, in the production and maintenance

In the production of A, regularly die on the corresponding parts of the oiler. Such as: the pressure ring, fillet drawing die; edge trimming die; flanging knife block etc..

B, regular waste on the waste channel hole trimming and punching die of cleanup.

3, production and maintenance after

The production of A, after a thorough inspection of themould.

B, die to conduct a comprehensive cleaning, ensure thecleanliness die.

C, will waste mold clean up, to ensure that no waste wastebox.

D, the mold and the use of state after the situation accurately feedback to die a.

Die two level maintenance

The maintenance work by the repair personnel to complete, and make records according to themaintenance. The following different parts the secondsecurity requirements and methods.

1, drawing die punch, die: convex, concave die drawing die main problems are raised and surface indentation,polishing and maintenance of die fillet surface parts. If thepit to repair welding of the mold, and then repair the cis.

2, the guide parts (guide pillar, a guide sleeve and guideetc.): die will stretch marks etc. phenomenon at work. The main reasons . The main reasons of lubricating oil anddirty and guide clearance offset etc.. The guide parts toeliminate stretch marks with an oilstone push to shun afterpolishing.

3, trimming knife: mould in use process parts prone tochipping and edge collapse phenomenon. It is time torepair welding repair of damaged blade mould.

4, spring elastic parts: in use process, spring is one of the most easily damaged parts mold, usually appear fracture and deformation. The approach taken is replaced, but thechange process must pay attention to the springspecifications and models, spring specifications by color,diameter and length of three identified, only in three under the same conditions may be replaced.

5, punch, Punch Set punch, die: the use of shock most of them adopted standard parts, die in use process, prone tobreak the punch bending and eating a bad phenomenon.Shock is generally eat bad. The punch and punch sleeve damage generally use the same specification parts for replacement. The parameters of the main working part ofthe punch size, installation size, length etc..

6, fastening parts: check whether the fasteners loose,damaged. Replacement approach is to find the same standard parts.
