Abstract
The invention relates to a mold inner-film cutting machine. The mold inner-film cutting machine comprises a male mold and a female mold arranged oppositely to the male mold. The edge of the female mold close to a product is provided with several first grooves and first raised parts, parts of the male mold corresponding to the first grooves of the female mold are provided with corresponding second raised parts, and parts of the male mold corresponding to the first raised parts of the female mold are provided with corresponding second grooves. When the male mold and the female mold are closed, the second raised parts of the male mold are inserted into the first grooves of the female mold and the first raised parts of the female mold are inserted into the second grooves of the male mold so that the film close to the edge of the product is cut off and thus bonding of film chips and the product are avoided, a follow-up film chip removal process is avoided and a production cost is saved.
Description
Technical field
The present invention relates to thin film shut-off mechanism in a kind of mould being applied to in-mold decoration processes.
Background technology
Decoration technique inside mold（IMD, English full name：In-Mold Decoration）, also known as exempt from application techniques, be international wind
The surface decoration technique of row, the transparent thin film of Surface hardened layer, the middle printing pattern layer being formed for ink, the back side is injection molded layers,
When adopting in this way, described thin film cannot be cut off by male model and master mold, causes the thin film of white space, i.e. thin film bits, with product
Product link together, and need follow-up step to consider thin film to be worth doing and remove, product otherwise can be caused bad.
Content of the invention
The present invention provides thin film shut-off mechanism in a kind of mould, and to solve in decoration technique inside mold, thin film bits are difficult with product
With detached problem.
For solving above-mentioned technical problem, the present invention provides thin film shut-off mechanism in a kind of mould, including the public affairs being oppositely arranged
Mould and master mold, described master mold is provided with some first grooves and the first projection, described male model and described mother near the edge of product
It is provided with the second projection matching, described male model is convex with first on described master mold at the corresponding position of the first groove on mould
Rise and be provided with, at corresponding position, the second groove matching.
It is preferred that described first groove is crisscross arranged with described first projection.
Thin film shut-off mechanism in the mould that the present invention provides, including the male model being oppositely arranged and master mold, described master mold is close
The edge of product is provided with some first grooves and the first projection, and described male model is corresponding with the first groove on described master mold
It is provided with second matching raised, described male model is provided with phase at corresponding position raised with first on described master mold at position
Second groove of coupling.When male model and master mold matched moulds, in the first groove on the on described male model second raised insertion master mold,
In the second groove on described master mold first raised insertion male model, thus the thin film that will be close to product edge breaks, keep away
Exempt from thin film bits to link together with product, save the procedure of processing of follow-up removing film bits, and then saved production cost.

Specific embodiment
In order to state the technical scheme of foregoing invention more in detail, being exemplified below specific embodiment proves that technology is imitated
Really；It is emphasized that these embodiments are used for the present invention is described and are not limited to restriction the scope of the present invention.
Thin film shut-off mechanism in the mould that the present invention provides, as shown in Figure 1 to Figure 3, including male model 10 He being oppositely arranged
Master mold 20, described master mold 20 is provided with some first grooves 22 and the first projection 23, described male model at the edge 21 of product 30
Be provided with the second projection 12 matching at 10 positions corresponding with the first groove 22 on described master mold 20, described male model 10 with
It is provided with, on described master mold 20 first raised 23 corresponding positions, the second groove 13 matching.When male model 10 and master mold 20
That is to say, that when master mold as shown in Figure 2 20 and male model 10 as shown in Figure 3 mutually fasten during matched moulds, on described male model 10
In the first groove 22 on second raised 12 insertion master molds 20, on the on described master mold 20 first raised 23 insertion male models 10 the
In two grooves 13, thus the thin film that will be close at the edge 21 of product 30 breaks, it is to avoid thin film bits are linked together with product 30,
Save the procedure of processing of follow-up removing film bits, and then save production cost.
It is preferred that please continue to refer to Fig. 1 to Fig. 3, described first groove 22 be crisscross arranged with described first projection 23 so that
Male model 10 forms the shape of serration type with master mold 20 touching position, improves the effect that thin film breaks, certainly, described master mold further
20 structures that can only comprise projection at the edge 21 of product 30, corresponding, described male model 10 also only comprises and institute
State the groove that projection matches, also can achieve the technical problem that thin film is cut off to be solved by this invention.
It should be noted that the concrete shape of described first groove 22 and the first projection 23, quantity and adjacent groove
Or the spacing between projection can be adjusted according to specific performance, do not limit herein.
In sum, thin film shut-off mechanism in the mould that the present invention provides, including the male model 10 being oppositely arranged and master mold 20,
Described master mold 20 is provided with some first grooves 22 and the first projection 23 at the edge 21 of product 30, described male model 10 with described
It is provided with the second projection 12 matching, described male model 10 and described master mold at the corresponding position of the first groove 22 on master mold 20
It is provided with, on 20 first raised 23 corresponding positions, the second groove 13 matching.When male model 10 and master mold 20 matched moulds,
22 in the first groove on described male model 10 second raised 12 insertion master molds 20, first on described master mold 20 raised 23 inserts
Enter in the second groove 13 on male model 10, thus the thin film that will be close at the edge 21 of product 30 breaks, it is to avoid thin film bits and product
Product 30 link together, and save the procedure of processing of follow-up removing film bits, and then have saved production cost.
Obviously, those skilled in the art can carry out the various changes and modification spirit without deviating from the present invention to invention
And scope.So, if these modifications of the present invention and modification belong to the claims in the present invention and its equivalent technologies scope it
Interior, then the present invention is also intended to including these changes and modification.
