Injection mold molding parts processing method and its manufacture precision

by:CSSSLD     2021-01-23
Plastic injection mold processing method which can be roughly divided into ordinary cutting machine tools machining, special processing, die locksmith three major
class. It is difficult to the traditional way of using ordinary machine tools or artificial processing complicated shape and high precision dynamic and fixed mode of manufacturing cycle parts or take a long, long workpiece.


25. 16. 1 parts processing method and the precision of


injection mold parts processing of the common machine tool should be able to achieve the precision and processing characteristics of view 'table 9 common processing methods and processing technology of injection moulds list'.


25. 16. 2 die locksmith processing


die locksmith processing refers to the file, shovel, scraping, grind cutting machine manual measures such as reserved by the machining allowance,
the mould semi-finished parts processing to meet the requirements of the pattern size, shape and surface roughness of qualified processing object, and through the
assembly assembly to conform to the requirements of the mould. Now move by numerical control machine tool, mould parts, precision reaches 0. Less than 5 mm, and then on the clamping machine research and manufacturing cycle is short, and good quality.


clamp processing is given priority to with manual operation, the use of tools and drilling machine to complete the workpiece machining, assembly and maintenance operations.


( 1) Fitter basic operation of the


1) auxiliary operation, namely according to the pattern on the bad or semi-finished workpiece MAO draw processing line operation.


(2) cutting operation has a chisel cutting, cutting, filing, tapping screw, screw, drilling ( Reaming, reaming) , scraping and grind mill and other operations.


assembling operation (3) the assembly, parts or components according to assembly drawings technical requirements into the process of the machine.


4. Maintainability, operation or maintenance of machinery, equipment maintenance in service, inspect and repair operations.


( 2) The characteristics of the benching


fitter is a complex and subtle, high technical requirements of the job. Pliers machining and mechanical machining compared with simple tools
and the advantages of convenient operation, wide adaptation of, can do some mechanical machining inconvenience or difficult to finish the work of
. It is an important type of work in machinery manufacturing and repair work, has a special and irreplaceable role. But benching lowe


dynamic strength, low production efficiency, technology requirements for bench is quite high.
