Description
Technical field
The present invention relates to mold design technical fields, and in particular to a kind of injection mould with two class triplasy running gate systems
Tool.
Background technique
Generally for single-chamber injection mold, form that shape is larger, complex-shaped product often selects drop gate or
Person's side gate and sub-marine gate are poured.And there are larger defects for drop gate: 1, it is relatively difficult to remove cast gate condensate；
2, there are apparent gate vestiges on plastic；3, it is easy to produce internal stress, plastic is caused to deform；4, near cast gate melt it is cooling compared with
Slowly, extend the injection moulding period, influence shaping efficiency etc..Although side gate is suitable for forming plastic of various shapes, but side
Cast gate the defects of there are weld mark easy to form, shrinkage cavity, bubbles, this is very unfavorable for there is the molding of the product of appearance requirement.
Sub-marine gate can solve this defect, but the molding of this large scaled complex product can then be produced only with sub-marine gate
Raw more waste materials are unfavorable for shortening molding cycle and save production cost.
Secondly, should ensure that melt throughput uniformly increases for the complicated die of radial diffusion.Wall thickness variation is too big
When, before thick wall part fills up, propulsion of the plastics at thin-walled can be slower and slower, it is possible to cause short penetrate.In order to guarantee zero
Part quality complies with standard, and control melt flow rate is extremely important, because it will affect molecules align and surface shape in part
State.
In addition, for there is the product of lateral cup aperture shape, due to lateral core pulling narrow space, cause about lateral cup aperture into
