Description
Technical field
The utility model is related to encapsulated injection molding technology field, specially a kind of ejecting push plate device.
Background technology
When the concavity product single to some structure features carries out demoulding processing, since interiors of products is without supporting point, and
Product surface is more demanding, internal again can not increase thimble, can only increase thimble in product bottom port face region to eject
Product, but the material used due to some products is PA6, this material inprocess shrinkage range and shrinking percentage are big, easily occur shrinkage cavity,
The problems such as deformation and sticking to mould, stripping means used at present are to carry out top punching (such as to product bottom port using more thimbles
Shown in Fig. 1), this mode thimble and product contact area are small, the discontinuity of product, and its are easy to happen showing for sticking to mould
As.
Utility model content
