Description
Technical field
The utility model relates to plastic mold demoulding mechanism technical field, specifically provide a kind of suitable for minimum processing space
Plastic mold demoulding mechanism.
Background technique
Currently, common or commonly used various plastic cement devices are all with plastic mould mostly come machine-shaping, such as electricity
Plastic shell, plastic cement device of keyboard of sub- product etc..
Because in plastic cement device often with the back-off for having various patterns or in be buckled to, therefore also corresponding configuration in plastic mould
There is the demoulding mechanism for the back-off of machine-shaping product or interior back-off.Come in plastic mould frequently with taper pin demoulding mechanism at present
Back-off in machine-shaping product, but taper pin is needed when carrying out stripping operation that processing space is big, product back-off amount is small, if processing sky
Between it is small or minimum, then taper pin cannot normally realize demoulding；And if product back-off amount is larger, it will occur strong de- and make
The drawbacks of being pulled at product.
In view of this, special propose the utility model.
Summary of the invention
