It connects and influences aluminum piston product competitiveness and manufacturing cost.Aluminum current Piston mould all uses integral structure with running gate system,
It is especially troublesome for the repair of mold.
Currently, aluminum piston die casting system is belonged to mostly after being digested and assimilated on the basis of " Imported " running gate system
" modified ".Improved running gate system devises a small riser above ingate, is only used for carrying out feeding to ingate.
Thermal center and dispersion heat are generated at ingate in order to reduce simultaneously.The running gate system and external mold integrated design, if cast system
System need change or replace, must just modify to entire mold, simultaneously for generated on piston blank shrinkage porosite, shrinkage cavity and
The defects of slag inclusion, is not easily controlled, and causes " safety coefficient " of mold low, there are certain risks.Generally speaking, aluminum current
Piston mould running gate system production there are the problem of it is main there are two：First, processing efficiency is low, replacement speed is slow, external mold running channel one
Body processing time consuming is laborious, can not share out the work and help one another；Second is that mold " safety coefficient " is low, outside piston shrinkage defect is not easy to control, outside
Mould running channel can not integrally ensure the sequencing of solidification.
