Abstract

The utility model relates to an in-mold transfer injection mold, which comprises: a mother mold, a middle plate and a male mold, a transfer film can be accommodated between the middle plate and the mother mold, and the middle plate can press the transfer film; the mother mold, the middle plate and the male mold can form a molding space together, wherein when a plastic material fills the molding space to form a plastic component, a decorative pattern on the transfer film can be transferred to the plastic component.

Description

The in-mold transfer printing injection mold

Technical field

The utility model relates to a kind of in-mold transfer printing injection mold, particularly a kind of in-mold transfer printing injection mold that is applicable to the section of having difference structure member.

Background technology

In-mold transfer printing is a kind of processing procedure of finishing parts injection molding and incrustation synchronously, the decorative pattern of the transfer printing of wanting is formed on the transfer film in modes such as printing or evaporations in advance, then this transfer film is placed between male model and the master mold, behind the matched moulds plastics are injected mould, with moulding one plastic components, and simultaneously decorative pattern is transferred to this plastic components, and treat behind the plastics solidification this plastic components to be ejected, promptly finish the plastic components that this has decorative pattern.

Figure 1A shows the schematic diagram of an existing in-mold transfer printing injection mold.This in-mold transfer printing injection mold 100 comprises a male model 110 and a master mold 120, this master mold 120 has the die cavity 121 of depression, this male model 110 has protuberance 111, running channel 112 and knock pin 113, and has a transfer film 130 between this male model 110 and this master mold 120.When this male model 110 and these master mold 120 matched moulds, the plastics of high heat are injected by this male model 110 and these master mold 120 formed spaces by running channel 112, with moulding one plastic components, and simultaneously the decorative pattern on the transfer film 130 is transferred to this plastic components, treat by knock pin 113 this plastic components to be ejected behind the plastics solidification, promptly finish the plastic components that this has decorative pattern.

Yet carry out above-mentioned in-mold transfer printing, the external form of plastic components need be subjected to many restrictions, and Figure 1B shows the schematic diagram of the plastic components 150 among Figure 1A.Must have gentle fillet 151 around the plastic components 150, and plastic components 150 cannot have obvious section difference and too big thickness, otherwise above-mentioned transfer film 130 can be damaged because excessively stretch, and decorative pattern can't be transferred on the plastic components 150 smoothly.

In view of the existing shortcoming of above-mentioned in-mold transfer printing injection mold, be necessary to propose a kind of in-mold transfer printing injection mold, need not have gentle fillet around the plastic components of producing, and the external form of plastic components can the section of having difference or bigger thickness.

Summary of the invention

The purpose of this utility model is for proposing a kind of in-mold transfer printing injection mold, need not have gentle fillet around the plastic components of producing, and the external form of plastic components can the section of having difference or bigger thickness, and section difference and big thickness place can not need any color of transfer printing.

For reaching above-mentioned purpose, the utility model provides a kind of in-mold transfer printing injection mold, and it comprises: a master mold; Plate in one can a ccontaining transfer film between plate and this master mold in this, but and should in this transfer film of plate pressure holding; And a male model, this master mold, plate and this male model can form a molding space jointly in this, and wherein, when a plastic material filled up this molding space and forms a plastic components, the decorative pattern on this transfer film was transferred to this plastic components.

Useful technique effect of the present utility model: by in-mold transfer printing injection mold of the present utility model, transfer film can not take place because excessively stretch and damaged situation, therefore the plastic components of producing need not have gentle fillet on every side, the external form of plastic components can the section of having difference or bigger thickness, and section difference and big thickness place can not need any color of transfer printing.

The specific embodiment

Fig. 2 A shows the schematic diagram of the in-mold transfer printing injection mold 200 of the utility model one preferred embodiment, this in-mold transfer printing injection mold 200 comprises: a plate 220 and a male model 230 in the master mold 210,, should in can a ccontaining transfer film 240 between plate 220 and this master mold 210, but and should in this transfer film 240 of plate 220 pressure holdings; This master mold 210, plate 220 and this male model 230 common molding space that forms when matched moulds in this, wherein, when a plastic material fills up this molding space and when forming a plastic components, the decorative pattern on this transfer film 240 is transferred to this plastic components.

According to present embodiment, male model 230 is provided with at least one running channel 231 and ejecting mechanism 232, by this running channel 231 plastic material is filled up above-mentioned molding space, forming a plastic components, and carries out ejecting of this plastic components by ejecting mechanism 232.

Fig. 2 B shows the schematic diagram of the plastic components 250 among Fig. 2 A.Above-mentioned decorative pattern is transferred to the part that plastic components 250 protrudes plate in this, transfer film 230 can not take place because excessively stretch and damaged situation, therefore plastic components 250 around not necessarily need to have gentle fillet, and plastic components 250 also can the section of having differ from or bigger thickness.

By in-mold transfer printing injection mold of the present utility model, transfer film can not take place because excessively stretch and damaged situation, therefore the plastic components of producing need not have gentle fillet on every side, the external form of plastic components can the section of having difference or bigger thickness, and section difference and big thickness place can not need any color of transfer printing.

Above-mentioned embodiment of the present utility model only is explanation technological thought of the present utility model and characteristics, its purpose makes those skilled in the art can understand content of the present utility model and is implementing according to this, when can not with qualification claim of the present utility model, be that all other do not break away from the various changes of the equivalence that spirit that the utility model discloses finishes or modify and all be encompassed in the disclosed scope of the utility model, all should be included in the scope of claims.
