1), measuring tools: caliper, micrometer, dial indicator, standard gauge block, standard corner block, turntable, angle gauge, projector, copier, etc.
2. Processing machinery and equipment: gong machine, lathe, grinder, drilling machine, CNC (computer gong), spark machine, wire cutting machine, etc. 3) Processing method and technology
Generally, the mold embryo is ordered directly from the mold embryo factory, and its processing method is omitted here.
According to the design drawing of precision injection mold processing, the processing of precision injection mold is arranged by ordering back the steel products such as mold blank, mold core, ranking, inclined top and insert. According to the processing technology, it can be roughly divided into two parts: rough machining of precision injection mold and fine machining of precision injection mold. Mold blank opening, rough mold opening and fine mold opening are carried out by a gong machine or a computer gong (it can also be processed by a mold blank factory, but the corresponding fees should be paid; In order to save costs, some small mold houses often process themselves, but the efficiency and accuracy are low. Other parts are also developed and designed with plastic molds and roughed into blanks, and then finished with computer gongs, cremation machines and wire cutting machines to meet the requirements of drawing accuracy, and finally assembled into mold blanks to become a complete set of molds. The process is probably like this: CNC machining of mold opening blank, mold core and line position, and copper machining.
Ignition machining cavity (EMD), fitter machining (die fitting), polishing (die saving), die fitting and die testing.
In actual manufacturing, several plastic mold development, design and processing technologies are intertwined, which requires plastic mold development designers and mold masters to make overall arrangements for each link. One wrong step and all the pots are negative! Rework often causes mold damage, and precision injection mold processing is not beautiful. If you want to remedy, you can only change the materials, which will increase the time and cost. Many times, time is the most important. At present, the competition in the precision injection mold processing industry is fierce, and customers are eager to give the mold room. If they can't deliver the molds on time, they will eventually lose customers! Brief introduction to the functions of various processing machinery and equipment;
1, gong machine, used for manually milling workpieces with simple and regular shapes, such as straight lines and diagonal lines; It is often used to process workpieces with low precision requirements, such as mold opening, mold core, wire cutting and so on.
2. Lathe, mainly used for machining circular workpieces, such as nozzles, locating rings, flanges, circular cores and circular copper pins. The accuracy can meet higher requirements.
3. Grinder, mainly used for leveling steel and grinding benchmark, can meet most accuracy requirements. 4. The drilling machine is mainly used for drilling holes, tapping teeth and drilling water holes.

It passes a very thin molybdenum wire through a hole punched in the workpiece in advance, controls the discharge and operation of the molybdenum wire according to the data in the computer, and cuts a set shape on the workpiece. Generally, the diameter of molybdenum wire is 0.07~0. 10mm, so the precision of its precision injection mold processing is also very high. Wire cutting is divided into fast wire cutting and wire cutting. Generally, the wire cutting machines in the mold room belong to fast wire cutting, but the wire cutting thinks that the processing speed of precision injection mold is very slow. Sacrificing speed for high precision is basically used for precision injection mold processing and some metal terminal molds. The unit price is 3~5 times that of the fast moving line. Need to mention a detail, that is, the water used for wire cutting is pure water. Of course, it is also numerically controlled and needs computer program control.
Need plastic mold parts processing, don't patronize Dongguan Jinpan Mold Co., Ltd., the quality is reliable. A mold processing supplier worthy of your ownership.
