Abstract
The utility model relates to a forming device of in-mold decorations and comprises a mold feeding device, a female mold, a male mold and an active part; wherein, the mold feeding device is used for sending a thin film into between the female mold and the male mold; the active part is arranged between the female mold and the male mold to be used for enclose a forming cavity with the female mold and the male mold when the molds are integrated. The forming device makes use of the forming cavity enclosed by the female mold, male mold and the active part between the female mold and the male mold, to ensure the depth of the forming cavity without influencing the coating quality of the thin film, which avoids the deformation of letters or patterns caused by the stretching of the thin film; the thin film is not coated on a side wall of the active part of the forming cavity, thus realizing that the thin film is not deeply coated into the forming cavity.
Description
Technical field
The utility model relates to a kind of shaped device, particularly a kind of shaped device that can form the in-mold decoration of decorative pattern on profiled member.
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, enhances productivity.Figure 1 shows that the schematic diagram of the employed former of a kind of decoration technique inside mold.This former comprises film feeder 102, film 104, has the mould of master mold 106 and male model 108.
Send die device 102 to be a pair of traction wheel that is used for tracting film 104 that is divided into the mould upstream and downstream, be used for film 104 is sent between master mold 106, the male model 108.
In conjunction with shown in Figure 2, before the matched moulds, film feeder 102 is sent into film 104 between master mold 106 and the male model 108 along the direction of the bearding of male and female mould 108,106, makes film 104 be covered in master mold 106 surfaces, thereby forms an airtight space between film 104 and master mold 106.Vacuum extractor is extracted the air of this airtight space out by air discharge duct 112, film 104 is sucked in die cavity 110, thereby make film 104 tightly be fitted on the inwall of die cavity 110.During matched moulds,, make film 104 be pressed and be fixed in the mould towards master mold 106 direction pressing male models 108.
In in-molded processing procedure, prior art only relies on to vacuumize under the normal temperature state film 104 absorption is positioned in the die cavity 110 of master mold 106, therefore the pull and stretch degree of film 104 is subject to 104 limit of stretch when the normal temperature state of film, for example may breakage when film 104 itself is stretched above its nature 20% or broken; Moreover when die cavity 110 design of master mold 106 has low-angle when acute angle angle (particularly) structure, owing to vacuumize the restriction that the material of the size of negative pressure of generation and film 104 is out of shape under the normal temperature state, film 104 also is difficult for fully agreeing with mutually with the shape of die cavity 110, influences the quality of in-mold decoration.
In addition, if need the product of moulding only need form literal or pattern in its bottom or bottom periphery, and need not form literal or pattern at its side, then not need film is laid in the die cavity fully, prior art is difficult for realizing.
The utility model content
In view of this, be necessary to provide a kind of do not need with the big degree of depth of film be laid in the shaped device of the in-mold decoration in the die cavity.
A kind of shaped device of in-mold decoration comprises a film feeder, a master mold, a male model and a movable part.Described film feeder is used for film is sent between described master mold and the described male model, and described movable part is located between described master mold and the male model, is used for when matched moulds and described master mold, described male model surround a forming cavity jointly.
Movable part and master mold, male model that the shaped device utilization of above-mentioned in-mold decoration is arranged between male model and the master mold surround needed forming cavity jointly, in the degree of depth that guarantees forming cavity, do not influence the laying quality of film, the literal that produces because film is stretched or the distortion of pattern have been avoided, and film can not be laid on the sidewall at forming cavity movable part place, thus realize not with the big degree of depth of film be laid in the forming cavity.

The specific embodiment
As shown in Figure 3, a better embodiment of the shaped device of the utility model in-mold decoration comprises film feeder 202, film 204, master mold 206, male model 208 and movable part 210.
Master mold 206 offers die cavity 212 towards the one side of male model 208, relative another side to master mold 206 runs through and offers two air discharge ducts 214 that communicate with die cavity 212 master mold 206 from die cavity 212 diapires, and air discharge duct 214 links to each other with vacuum extractor (figure does not show) away from an end of die cavity 212.
As shown in Figure 4, before the matched moulds, send die device 202 that film 204 is delivered between master mold 206, the male model 208.Male model 208, movable part 210 bleed by air discharge duct 214 simultaneously, thereby film 204 are suppressed and are fitted on the die joint of master mold 206 by movable part 210 to the motion of master mold 206 directions.During matched moulds, male model 208 continues the direction motion to master mold 206, make movable part 210 closely offset with master mold 206, male model 208 respectively, movable part 210 is positioned at auxiliary section 216 peripheral part with die cavity 212, auxiliary section 216 and male model 208 and surrounds formation die cavity 220 jointly.
During moulding, by injection molding mouth 218 injection in forming cavity 220, up to being full of forming cavity 220.Pressurize cooling, moulding product are taken out in last die sinking, and the transfer printing layer on the film 204 will separate with film 204 and to be attached to the moulding product surperficial.Start film feeder 202, the part of film 204 in this molding cycle shifts out between master mold 206, male model 208, and begins next molding cycle.
As shown in Figure 5, another embodiment of the shaped device of the utility model in-mold decoration and above-mentioned better embodiment structural similarity comprise film feeder 302, film 304, master mold 306, male model 308 and movable part 310.Do not offer die cavity on the master mold 306, still be provided with auxiliary section 312 on the male model 308, the part that is positioned at around the auxiliary section 312 by auxiliary section 312, movable part 310 and the male model 308 of master mold 306, male model 308 between master mold 306, the male model 308 surrounds a forming cavity 314.The sidewall towards the formation of the sidewall between master mold 306 and the male model 308 forming cavity 314 of movable part 310.When film 304 is sent between master mold 306 and the male model 308 by film feeder 302, can directly film 304 be fitted tightly on the bottom surface of forming cavity 314.The flow process that the shaped device of the in-mold decoration of this embodiment carries out the injection moulding is identical with above-mentioned better embodiment, repeats no more.
Movable part and master mold, male model that the shaped device utilization of above-mentioned in-mold decoration is arranged between male model and the master mold surround needed forming cavity jointly, simultaneously, film is suppressed on master mold, in the degree of depth that guarantees forming cavity, do not influence the laying quality of film, the literal that produces because film is stretched or the distortion of pattern have been avoided, and film can not be laid on the sidewall at forming cavity movable part place, thus realize not with the big degree of depth of film be laid in the forming cavity.
