Precision mold manufacturing depends on the advanced processing equipment.
And main technology with precision mold manufacturing CNC milling, wire cutting, edm, grinding, car, measurement, automation and so on.
a, CNC milling
ordinary milling machine from the traditional to the three-axis machining center, then to today's high-speed five-axis milling, make again how complex 3 d surface parts processing, almost all can become a reality, the hardness of materials is no longer a problem. The main plastic mold cavity, profile are done by CNC milling, the rapid development of plastic mould manufacturing industry is mainly thanks to CNC milling technology innovation.
2, wire cut processing
wire cutting processing is mainly used for all kinds of stamping die, plastic mould, such as powder metallurgy mold 2 d and 3 d straight grain surface parts processing. Processing of stamping die proportion is the largest, fixed plate stamping die punch, punch, concave die and the stripper plate, and many other precise hole machining, wire cutting processing is indispensable key technology. In the manufacture of injection molds, common applications are insert hole, pinhole, inclined top hole, cavity qing Angle and sliding block processing, machining accuracy requirements are not generally stamping die is so high.
walking silk processing is a method of high precision processing high-end machine tools machining precision can reach less than 3 microns, the surface roughness can reach Ra0. 05μm。 Has 0 can be realized. 02 ~ 0. 03
㎜ wear silk electrode wire cutting, the cutting efficiency of practical can reach about 200 ㎜ 2 / min.
3, edm
edm is suitable for precision small cavity, narrow gap, groove, such as the corner of complex parts processing. When the tool is difficult to reach the complex surface, in the depth of cutting are needed, in particularly high length-diameter ratio, edm is superior to the milling process. For high technology parts processing, milling and then discharge electrode can improve the success rate, compared with high expensive tool than electro discharge machining is more suitable. In addition, in the provisions will be electric spark machining, electric spark machining surface to provide fire decorative pattern.
4, grinding machine processing
grinding machine is carried out on the parts surface finish machining of precision equipment, especially the hardened workpiece. Mould processing using grinding machine is mainly surface grinder, universal inside and outside grinder, grinding coordinates ( PG optical curve grinding machine) 。
xiaoping grinding machine is mainly used for processing small size of mold parts, such as precision insert, precision mould kernel, slider, etc. The floods grinding machine used to larger template processing. Now, surface grinding machine high speed grinding wheel linear velocity and worktable movement has become a common trend, as a result of the linear guide, linear motor, such as static pressure guide screw features advanced technology, there has been a great improvement in speed, and constantly improve the technology of grinding wheel dressing.
5, numerical control lathe
CNC lathe is also commonly used mold workshop processing equipment. The range of axisymmetrical parts has been all is processing. Due to the height of the development of numerical control technology, complex shape of rotors can be simple and easy implementation, through programming and machine tool can automatically replaced, greatly improved the production efficiency. Numerical control lathe machining accuracy and manufacturing technology has become increasingly perfect, even has a tendency to car for grinding. Commonly used to processing and mould of round insert, hold the head, locating ring and other components, widely used in the pen mould, bottle mould. Advanced CNC lathe, in fact, its function is no longer limited to the 'car', have been expanded to car milling compound machine tool, a complex, multistep parts, and even can be done all one-time processing.
6, measuring
from the early stages of mold design of digital surveying and mapping, to mould processing process measurement, to mold acceptance and late mold repair measurement, high precision measuring equipment play an important role.
7, fast clamping positioning system and automation
a mold parts often need to use a variety of craft can be built. This process, the clamping and correction of parts to be constantly, spent a lot of time, the machine is idle, expensive equipment its processing capacity has not been fully utilized. With the increasingly fierce competition in the field of manufacturing. A shorter production cycle is the development trend. Foreign jig maker, using a set of stable and precise benchmark system, realized the milling, vehicles and measurement, such as electrical discharge machining process unified benchmark swaps, it takes only a minute or so fast on the machine tool clamping electrode and alignment, repetitive positioning accuracy within the 3 microns, maximum limit reduces the setting time, great increase in the actual running time of machine tool. In fact, this is an essential condition of modern production.
