Background technology
Along with the fast development of China's automobile industry, the fast development of automobile die technology, vapour are also driven
Car mould and product have huge market, and this is also due to need in the finished product in automobile making substantial amounts of
Auto parts and components ensure.In main aspects high-end zero such as body of a motor car part now, engine products
Our main or import of parts, mould equipment is the pith in automobile making, but the precision of China
The manufacturing capacity of mould and product manufacturing technology accumulation deficiency.Also zero, the automobile of high-grade car has been resulted in
Part mould is nearly all the phenomenon of imported product.
From the cylinder body die casting of the heart electromotor of automobile to body of a motor car complexity plastic parts, each operation
It is all that requirement is higher.In order to alleviate weight and reduce structural complexity, the light metal such as aluminium alloy, with
And the application that double-material injection-molding parts are on automobile will get more and more, automotive light weight technology, new material shape
Mould, multistation progressive die are all the guarantees of the development advancing Automobile Self-brand.
At present, the two-shot molding process of large complicated automobile injection parts, it is typically all the secondary injection used
Moulding formula, also known as single mode dijection form, including rotary, portable etc..Tradition Complicated Automobile parts are double
Color injection molding manner, has the feature to be, after being the most once molded, and the first color product approval,
Carry out the second color injection, form double-colored product.Many problems so will be caused to occur, the first first color
Product can produce the deformations such as contraction, distortion after sizing, causes producing gap when second time injection,
Die joint is formed batch cutting edge of a knife or a sword；Next to that, the first color product has been shaped, then carries out the second color product note
Mould, merging it is possible that insufficient situation between the two, affect the quality of double-colored product.
This situation is when using the plastic material that two kinds of hardness soft, hard are different to be molded, because deformation
Even more serious etc. batch cutting edge of a knife or a sword phenomenon of former soft or hard glue (the most double-colored material) die joint thus resulted in, often make
Become the defective products of more than 85%, have a strong impact on product quality.
Therefore, the technique and specially of a kind of double-shot moulding being suitable for the products such as large complicated automobile component is researched and developed
With mould, just become the most urgent.
Summary of the invention
For the above-mentioned deficiency of prior art, it is an object of the invention to, it is provided that one can avoid die joint
