What are the factors that affect the quality of mold parts?

I believe we all know that mold accessories are mainly parts or components installed on the mold, which can be widely used in all kinds of plastic molds, stamping molds, automobiles, electrical and aviation manufacturing fields.

However, for mold parts, the quality is good, it means that the life will be higher, therefore, to understand the factors that affect the quality of mold parts is a problem that we are very concerned about. So do you know what factors affect the quality of mold parts?

The factors that affect the quality of mold parts are as follows:

1, the rationality of mold accessories design

Mold accessories designers should first fully understand the user's use requirements and working conditions, die-casting force, and then choose the right material according to the use requirements and working environment to understand the material die-casting performance. In the design of mold accessories, special attention should be paid to the premise of meeting the requirements of use, and the die-casting structure should be simple as far as possible. The wall thickness is appropriate and uniform, and the necessary mold slope is left, otherwise it will lead to pits, pores, shrinkage, underpressure, tensile marks, cracks, deformation and other defects on the casting. The requirements for the dimensional accuracy of the casting should be reasonable, otherwise it will bring unnecessary trouble to the mold design, mold processing, process conditions development and management, and will cause a large number of unqualified products.

2, mold structure, processing accuracy and mold materials

Die casting selection of die parts is closely related to product quality such as die casting, die design, processing and die material selection. Mold structure is unreasonable, mold accessories no matter what measures are taken from the process, it is difficult to make the product qualified. In addition, the mold materials, mold processing accuracy, surface roughness, processing marks, heat treatment of small cracks, nitride layer thickness and mold assembly of heat-resistant mold accessories will affect product quality and mold life.

3, the shrinkage rate of mold accessories materials

The shrinkage of the casting material, generally in the form of an average percentage or a percentage of a certain range of change, usually the average shrinkage of the material is selected. For the design of high-precision die castings and molds of mold accessories, special attention should be paid to the selection of material shrinkage, if necessary, you can first test the mold, obtain the required data in the test mold, and then design and manufacture the production number of large molds.

In summary, it is the factors that affect the quality of mold parts. In order to better ensure the quality of mold parts, we in the design process, as far as possible to choose a good structural scheme, mold parts designers must fully consider the technical requirements of the parts and its structure, and must meet the mold manufacturing process and feasibility.
