Today is the Lantern Festival, after yuanxiao this year is so thoroughly. Lantern Festival now is not yet a legal holiday, so believe that a lot of friends are also trying to work today? Today the dongguan Plastic mold factory, editor of take you to look at the design of the plastic mould process.
< a > plastic technical requirements:
Use, usage, work requirements, size precision, roughness and other small plastic parts molding technology design principle, die structure rationality and so on comprehensive analysis.
< 2 > settlement parts weight selection to nominal injection volume, injection machine choice injection machine, determine the cavity number (a set of mold to shape different set of another piece).
< 3 > analysis parts determine the forming scheme
Parting surface, parting ways, lateral concave hole forming method, pouring water forms. Gate location, and method of heating cooling system and the other.
< 4 > drawing mould plan sketch
Drawing die at the beginning of project, and choose injection machine parameter.
< 5 > calculation
Forming another job size calculation, mechanical parts strength and stiffness computation.
< 6 > draw assembly drawings
Claim size assembly drawings (overall dimensions, special size; positioning ring size) with size assembly dimension limit, technical writing table.
< 7 > draw another piece
Paintings such as graphics, note the size, precision, roughness, and material requirements. Material and heat treatment technology conditions.
