On sight face 42, to prevent the injection mould product 4 after type core is separated with type chamber from tilting.Specifically, the locking piece 7
On be also connected with oil cylinder 8, when needing to release to the limitation of injection mould product 4, oil cylinder 8 drives locking piece 7 to produce far from injection mould
Product 4.
Embodiment 3
The present embodiment provides a kind of mold stripping methods to be included the following steps using the mold provided in embodiment 2：
In the appearance 41 of the intracavitary injection molding mould product 4 of type；
Locking piece 7 is detached from from the non-appearance face 42 of injection mould product 4；
Injection mould mould unloading structure is acted on the non-appearance face 42 of injection mould product 4；In this step, pass through note first
The horizontal extension pawl 21 of mold mould unloading structure extracts the side of injection mould product 4 from type chamber, then passes through injection mould depanning
The horizontal extension pawl 21 of structure extracts 4 entirety of injection mould product from type chamber.
It should be noted that in above-mentioned process, the sequence between several steps be not it is unique, can basis
Specific operating condition is changed.For example, selection " takes off locking piece 7 from the non-appearance face 42 of injection mould product 4 in the present embodiment
From " be arranged before " on the non-appearance face 42 that injection mould mould unloading structure is acted on injection mould product 4 ".It, can as modification
Sequence between the two to be converted.
In the present embodiment, by mold stripping method proposed in this paper, injection mould product is directly extracted from type chamber, injection mould
Mould unloading structure acts directly on non-appearance face, and non-appearance face is arranged on the back side of appearance, and the structures such as sliding block directly act on
On non-appearance face, even if generating parting line at this time, since parting line is hidden in behind appearance, user will not be seen
Observe parting line.
Meanwhile during depanning, by injection mould mould unloading structure, injection mould product is driven to leave type chamber, rather than it is existing
There is band ejector half chamber common in technology to be detached from injection mould product, realizes the multiple and different directions of looking products without parting line
Depanning, avoids in appearance that there are parting lines, meets external appearance characteristic and quality requirement, improves product competitiveness.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
