The sliding block device of the injection mould can be widely applied to the injection mould, in particular to the injection mould which is not easy to demould and is back-off.
Description
Technical field
The utility model belongs to the injection mold field, relates in particular to a kind of injection mold slide block device.
Background technology
Nowadays, making plastic product with injection mold is comparatively common plastic product manufacturing process.In injection mold, often have the mould structure that slide block is loosed core; most of plastic product has only place's back-off or has many places back-off direction identical; at this moment need only do the demoulding of just can loosing core smoothly of slide block shovel based structures; but for specialities; shape is different from common structure; the many places back-off that different directions is arranged, adopt slide block shovel based structures just can not a die sinking and also product be out of shape also wayward.
The utility model content
The purpose of this utility model is to provide a kind of injection mold slide block device, and being intended to solve injection mold has the plastic product of many places back-off to be difficult for the demoulding and the uppity problem of distortion at some different directions of manufacturing.
The utility model is to realize like this, a kind of injection mold slide block device that is used for comprises a big slide block, and described big slide block places on the injection mold, described big slide block is provided with first small slide block and second small slide block, and described first small slide block and second small slide block all flexibly connect with big slide block.
The utlity model has following technique effect:
1, first small slide block of the utility model setting can be extracted out from big slide block from different directions respectively smoothly with second small slide block, thereby the injection mold direct demold that can effectively avoid general slide block shovel based structures draws distortion with the particularly back-off place scratch of injecting products of injecting products;
2, adopt technical solutions of the utility model after, during the injection mold die sinking, the die sinking that takes the lead in of first small slide block, can discharge the deformation space of plastic product, take the mode plastic product of whole demouldings to be out of shape uncertain comparing with the injection mold of general slide block shovel based structures, the plastic product distortion that the utility model is produced is only at the first small slide block place, by the deflection that precomputes plastic product do corresponding correction, can significantly reduce the deflection of the plastic product that injection mold produces to being out of shape corresponding part with plastic product on first small slide block.
