How about an example of an application technology to improve the life of the mold

I raise the mold in practice.

The method of service life:

1. Keep the position of the mold parts stable.

When the mold is working, all the parts on the mold are required to maintain a stable design position, and the mold processing clearance includes the uniform fit of the convex and concave die clearance such as punching, bending, and forming, which is an important aspect of controlling the relative position.

2. Material control in stamping.

In the whole stamping process, how to ensure the position and support of the stamped material, the stress and strain of the material, as well as the constraint of the material, should be considered.

3. Vibration control when the mold is working.

In order to prolong the life of the die, measures should be taken to prevent skew or twist caused by punch vibration when the effective part of the punch is intentionally lengthened.

4. Waste control of workpieces.

The rise of the scrap is due to the large gap, the tensile force acting on the material during blanking makes the stamping part smaller than the die hole, and due to the vacuum suction phenomenon caused by the close attachment between the bottom surface of the punch and the scrap, the scrap will reduce the life of the die.

5. Control of mold load.

It is required that the load center of the die and the pressure center of the punch are basically the same in the front, back, left and right directions.

In short, if the above five aspects are fully considered in the design of the mold, the service life of the mold can be greatly improved, the maintenance cost of the mold can be reduced, and the economic burden of the enterprise can be reduced.

Design, manufacture and mold life of precision volumetric forming molds.

Abstract] The relationship between the life of precision volumetric forming (precision forging) die and the design and manufacture of the mold is discussed. The use of advanced design means to reasonably design precision volume forming parts (precision forgings), forging process, mold structure, selection of mold materials, the formulation of forging specifications and heat treatment processes of die steel, and the reasonable determination of machining technology and machining accuracy, can greatly improve the life of molds.

Factors that improve mold life.

First, reduce the mold repair on the machine.

Second, the mold should be maintained daily.

Third, the mold must be kept clean and tidy.

Improving the life of the mold and reducing the cost of the mold is contradictory in a sense, and I don't know if the landlord is talking about a cold stamping die or a plastic mold, the following are general empirical measures:

1. Starting from the design of the mold process, try to minimize unnecessary process settings under the condition of ensuring the size requirements of the product.

2. The structure of the mold can ensure its size and reduce the unnecessary structure 3. Use good raw materials for the key parts of the mold, pay attention to the scope of good raw materials, and participate in the work part with knowledge 4. Select the appropriate standard parts according to the amount of the product.

5. Sometimes the rework caused by fitter assembly, design errors and processing errors is also a part of the mold development cost, so controlling the rework of abrasives is also a measure.

Hope it works for you.

5. Sometimes the rework of Sun Shixiao caused by fitter assembly, design errors and processing errors is also a part of the mold development cost, so controlling the rework of abrasives is also a measure.

Hope it works for you.

Factors that improve mold life.

First. Reduce the number of molds repaired on the machine.

Second, the mold should be maintained daily.

Third, the mold is a hu, hold the ruler, and the dust should be kept clean, and the pants should be sleepy.

The use of high-precision machine tool processing, the use of good mold Zhen Yingting steel, the necessary heat treatment to improve the hardness and wear resistance of the slippery steel. If necessary, the cavity of the mold can be nitrided to improve the hardness of the mold cavity and core.
