Mold is common in our daily life, but many people do not know this thing very well. In fact, the application of mold in our life, as large as cars, as small as mobile phone cases, are manufactured by mold. Today, Xiaobian is going to introduce to you the basic characteristics of hardware mold processing and the content of mechanical processing methods.

The basic characteristics of precision hardware mold processing:

(1) Machining accuracy requirements are higher than a pair of mold is generally composed of concave die, punch die and die frame, some may also be multi-piece integrated module. Therefore, the combination of upper and lower die, the combination of insert and cavity, and the combination between modules require high machining precision. The dimensional accuracy of precision die is often up to μm class.

(2) Complex shape surface Some products such as automobile covering parts, aircraft parts, toys, household appliances, the shape of the surface is composed of a variety of curved surfaces, so the mold cavity surface is very complex. Some surfaces must be dealt with mathematically. Mold master wechat: mujuren

(3) Batch small die production is not mass production, in many cases, often only one payment.

(4) In the process of multi-die processing, milling, boring, drilling, reaming and tapping are always used.

(5) The use of repeatable production mold has a life. When the use of a die exceeds its life, it is necessary to replace a new die, so the production of the die is often repetitive.

(6) Copying processing sometimes there is no drawing or data in the production of the mold, and it is necessary to carry out copying processing according to the real thing. This requires high precision imitation, no deformation.

(7) Excellent mold materials, high hardness of the main materials of the mold are made of high quality alloy steel, especially high life of the mold, often used Crl2, CrWMn and other Leytenite steel manufacturing. This kind of steel from blank forging, processing and heat treatment have strict requirements. Therefore, the preparation of processing technology can not be ignored. Heat treatment deformation is also a serious problem in processing.

What are the mechanical processing methods of the mold?

The mechanical processing methods of molds are generally divided into three kinds, which are:

(1) general mechanical processing

(2) mold copying processing

(3) Precision machining of mold

General mechanical processing is our common turning processing, in the mold turning processing of the main surface processing are: internal and external rotary surface, spiral surface, end face, drilling, knurling and so on; These are more common processing, of course, there are some special turning processing, such as: the joint cavity processing, spherical processing, multi-cavity mold processing and so on.
