What is a precision mold? What are the characteristics of precision molds?
Compared with ordinary molds, precision molds have higher requirements in the production process, for its raw materials, design, processing, precision, size and other content to achieve excellence, the processing process must be a high-precision processing and molding process. What are the specific requirements of precision mold characteristics, Ideal Vowin mold manufacturers of engineers for you to organize and collect relevant content.
Precision mold of the six molding requirements:
1, the product specifications of high precision, small size tolerance, with high precision specification boundaries;
2, the repeated precision standard of the product is high, to have the size of the day, month, year reliability;
3, the material of the mold is good, rigidity enough, concave mold of the external dimensions of precision, smoothness and its template between the accuracy of high;
4, the selection of high-precision plastic machine to replace the basic plastic machine;
5, the selection of high-precision molding process;
6, the selection of raw materials into high-precision molding.
Precision mold processing focus is definitely on precision, precision mold for dimensional tolerance requirements are very high, generally in ± 0.005. Many precision molds of the main specifications are not allowed to have a slope, but the mold production will generally be flexible to use the tolerance level as well as not too much inclination, such as drive gear mounting column head, and so on. Precision molds in the design of drawings must be more consideration of the operability and controllability of the processing, in order to ensure the smooth progress of processing.
Four major characteristics of precision molds
1, Wear resistance
Embryo material in the injection mold concave mold plastic deformation transmutation, along the mold cavity surface both circulation and rolling, so that the mold cavity appearance and the embryo material caused by intense friction, which led to the mold due to breakage and invalid. Therefore, the corrosion resistance of the material is one of the most basic and important characteristics of the mold.
Strength is the primary element that jeopardizes the wear resistance. In general, the higher the strength of the mold parts, the smaller the wear rate, the higher the wear resistance. In addition, the wear resistance performance is also related to the type, total number, shape and size of the carburized body in the material all over.
2, strong ductility
Most of the mold operating standards are very extreme, some often bear a large impact load, resulting in brittle. In order to avoid mold parts in the work when suddenly brittle fracture, high-precision hardware mold to have high hardness and ductility.
The ductility of the mold depends on the carbon content, grain size and structure of the raw material. Precision mold manufacturing.
3, fatigue cracking characteristics
Mold work link, in the cycle of bad pressure for a long time under the action, easy to cause fatigue rupture. Its type has small kinetic energy repeated impact fatigue rupture, tensile fatigue rupture, touch fatigue rupture and bending fatigue rupture.
The fatigue cracking characteristics of the mold key in its compressive strength, ductility, strength and its raw materials in the composition of the adulterants.
4, High temperature characteristics
When the operating temperature of the mold is high, it will reduce the strength and hardness, resulting in the initial breakage of the mold or cause plastic deformation and ineffective. Therefore, precision hardware mold steel should have high quench resistance reliability to ensure that the mold in the ambient temperature, can have high strength and compressive strength.
