Abstract
The utility model relates to a forming device of in-mold decorations, comprising molds and a thin film with decorations; wherein, the molds comprise a male mold and a female mold which is provided with a cavity; the thin film is arranged on an inner wall of the cavity and stretches outside the cavity; the part of the thin film out of the cavity is pressed on a parting surface between the male mold and the female mold; the depth of the cavity is fuller than the height of forming parts to be formed. The depth of the cavity is fuller than the height of forming parts and the thin film does not bend at an end edge of the forming part, which can avoid the loss of decoration letters or patterns in the mold because of the bending of the thin film in the cavity and ensure the completeness and rate of finished products of the forming parts.
Description
Technical field
The utility model relates to a kind of shaped device, particularly a kind of shaped device of in-mold decoration.
Background technology
When utilizing Shooting Technique to form plastic products, usually need on plastic products, draw ornamental literal or pattern.Commonly used drafting literal or method of patterning are the method for secondary operations, after the plastic products injection moulding being finished, print, operation such as spraying the final plastic products with literal or pattern that form again on the plastic products of moulding that is:.
The operation of the method for secondary operations is comparatively loaded down with trivial details, and its production cycle is also longer.The technology of in-mold decoration can shorten the production cycle, has improved production efficiency.Figure 1 and Figure 2 is the schematic diagram of the employed shaped device of a kind of decoration technique inside mold in the prior art.This shaped device comprises that a cover has the mould 20 and film 30 of die cavity 10, and mould 20 comprises male model 22 and master mold 24.Film 30 is laid between male model 22 and the master mold 24, and fits on the inwall of die cavity 10, and the two ends of film 30 are pressed together on the die joint of male model 22 and master mold 24 joints.
The matrix of film 30 is provided with the transfer printing layer 32 of ornamental literal of tool or pattern.During moulding, plastics are injected in the die cavity 10 between male model 22 and the master mold 24, after the cooling die sinking, transfer printing layer 32 separates with the matrix of film 30 and attached on the profiled member 40, thereby can form the plastic products that have literal or pattern through single injection-molded.
Because film 30 is to bend at die cavity 10 inwalls and die joint intersection, is easy to generate transfer printing layer 32 and can not be properly fit onto situation on profiled member 40 edge surfaces.At this moment, formed literal or pattern promptly can produce disappearance on profiled member 40, thereby influence the integrality and the yield rate of product.
The utility model content
In view of this, be necessary to provide a kind of shaped device of in-mold decoration, it can form complete literal or pattern at the edge of profiled member.
A kind of shaped device of in-mold decoration comprises the film that mould and tool are decorated.Described mould comprises male model, master mold.Described female film is provided with die cavity, and described film portion is positioned on the inwall of described die cavity and extends to described die cavity outside.The part in described die cavity outside of described film is pressed on the die joint between described male model, the master mold.The degree of depth of described die cavity is greater than the height of the profiled member of need moulding.
A kind of shaped device of in-mold decoration comprises the film that male model, master mold and tool are decorated.Described master mold is provided with die cavity, and described film is located on the described die cavity inwall, and it is outer and be pressed fixing to extend to described die cavity.Described male model is provided with one and is step-like auxiliary section, and described auxiliary section comprises first auxiliary section and second auxiliary section, and described first auxiliary section and described second auxiliary section are stretched into inner surface and the ora terminalis that is used to form the profiled member that needs moulding in the described die cavity respectively.
The degree of depth of the die cavity of the shaped device of above-mentioned in-mold decoration is higher than the height of profiled member, on male model, be provided for extending in the die cavity with the inner surface of formation profiled member and first auxiliary section and second auxiliary section of ora terminalis, thereby film does not bend in the ora terminalis place of profiled member, thereby can avoid film in die cavity, to produce bending and the situation of in-mold decoration literal or pattern disappearance occurs, guarantee the integrality and the yield rate of profiled member.

Fig. 1 is the partial sectional view of a kind of shaped device of in-mold decoration in the prior art.
Fig. 2 is the partial sectional view of shaped device when moulding of in-mold decoration shown in Figure 1.
Fig. 3 is the partial sectional view of the shaped device of the utility model in-mold decoration.
Fig. 4 is the partial sectional view of shaped device when moulding of in-mold decoration shown in Figure 3.
The specific embodiment
See also Fig. 3 and Fig. 4, the better embodiment of the shaped device of the utility model in-mold decoration comprises mould 50 and film 60.
During molding mold-closing, the auxiliary section 57 of male model 52 is stretched in the die cavity 56 of master mold 54.The part that film 60 is positioned at die cavity 56 is fitted on die cavity 56 inwalls.Film 60 is on the part of die cavity 56 outsides is pressed on die joint between the male and female mould 52,54.Injected plastic in die cavity 56 fills up die cavity 56 to form a profiled member 70.The ora terminalis of the opening part of profiled member 70 is formed at 574 places, second auxiliary section of male model 52.During the demoulding, male and female mould 52,54 is separated, transfer printing layer 62 breaks away from film 60 and stays on the profiled member 70, to form required literal or pattern.
Compared to prior art, the degree of depth of the die cavity 56 of above-mentioned shaped device is higher than the height of profiled member 70, the die joint 58 of the ora terminalis of profiled member 70 and master mold 54 leaves one section predetermined distance, film 60 does not bend in the ora terminalis place of profiled member 70, thereby can avoid film 60 to produce bending and make the ora terminalis outer surface of profiled member 70 situation of ornamental literal or pattern disappearance occur, guarantee the integrality and the yield rate of profiled member 70 at profiled member 70 ora terminalis outer surfaces.
