Description
Technical field
The mould structure from dynamic circuit breaker cast gate is broken the present invention relates to a kind of mold more particularly to a kind of sliding block.
Background technique
It is higher and higher to production efficiency and product appearance requirement in modern injection molding production process, improving production efficiency
Simultaneously to guarantee product appearance quality requirement, therefore, the automated production of mold comes into existence as the situation requires, i.e., die sinking ejection when product with
Runner has been automatically separated.Currently, there are sub-marine gate, spot pouring mouth and hot flow paths directly to put in product for die automation production
These three upper modes.But many products are because of the limitation of structure and appearance requirement, be not available three of the above cast gate mode and can only
Using side gate into the mode of glue.
However the prior art is Chinese, side gate is opened product and runner when ejecting into glue and is not possible to realize separation, i.e. runner
It is connected with product by cast gate, therefore to carry out secondary operation separates product with runner.And secondary operation is lacked there are following
Fall into: worker needs to carry out cast gate pruning modes, large labor intensity, and efficiency will be greatly reduced；The product in secondary processing process
The phenomenon that having residual or starved with the runner place of separation, unsightly product appearance quality will receive influence, product report for cast gate trimming
Useless rate can also improve.
Summary of the invention
The purpose of the present invention is to provide a kind of sliding blocks to break the mould structure from dynamic circuit breaker cast gate, to realize product and stream
Road is automatically separated, and without human intervention, to improve production efficiency, reduces scrappage.To achieve the above object, originally
