Description
Technical field
The invention relates to injection mold technical field, relates in particular to a kind of inverted mold that is suitable for the improvement of thin-wall product.
Background technology
Along with the development of mobile phone industry, mobile phone products is more and more thinner, and common mould structure has been difficult to meet the demand of part thin-wall product now.
For thin-wall product, mobile phone battery cover for example, for fear of the outward appearance that affects product, the position that enters Jiao Kou of the mould of ordinary construction can be very restricted.In injection mold structure design, generally, by a running gate system being set on solid plate and being provided with an ejection system on dynamic model, during die sinking, by injection machine, drive thimble ejecting product.
Yet the set-up mode of above-mentioned injection mold can make product one side produce gate vestiges because entering glue, another side ejects vestige because thimble ejecting product produces, thereby is difficult to guarantee the presentation quality of product.If for fear of affecting presentation quality, can not from product just or reverse side enter glue, and adopt, dive under water into the words of glue mode, from outer circumferential side, enter glue, will make so sizing material in die cavity, fill difficulty, thereby cause injection pressure large, injection pressure loss is many, and then has increased injection moulding cost.
In addition, due to processing technology, usually can there is mismachining tolerance in the end face between moving platen and solid plate, when mismachining tolerance is larger, can make to be installed on the core rod discontinuity between moving platen and solid plate, finally directly affects the quality of injecting products.
