Description
Technical field
The utility model belongs to plastic injection technique field, is specially in-mold decoration injection molding mould.
Background technology
In-mold decoration (In ModeDecoration, IMD) processing procedure, include in-mold transfer printing (In Mold Roller,
IMR), in-mold label (In Mold Label, IML) and mould internal shaping (In Mold Forming, IMF) etc..Wherein, in mould
Transferring (IMR) is printed in ink on the plastic cement carrier film for possessing release ability, to form decorating film.Treat plastic injection in
After be combineding with each other on plastic cement carrying mould with ink, you can peel off the carrying mould, and make modeling of the ink " transfer " to after shaping
Glue finished surface；On the other hand, in-mold label (IML) and mould internal shaping (IMF) etc. are then first to prepare a decorating film, the dress
Ink is printed in a hardened layer by decorations film, then a plastic layer is covered on the ink, makes ink clamping in the hardened layer
Formed between the plastic layer, which is attached in the plastic cement finished product after plastic injection is formed, and turns without such as in mould
Print (IMR) processing procedure peels off plastic cement carrier film.
In-mold decoration (IMD) processing procedure, first must insert decorating film in the die cavity being made of male model and master mold, in order to
Offset will not be produced because pressure or speed is projected by ensuring the position of the decorating film, and the plastics for causing to project can not be pasted accurately
Together in the decorating film surface.Therefore, can often utilize by the marginal portion of the decorating film press in the male model and master mold it
Between, and fix the relative position of the decorating film and die cavity.However, after the decorating film is fixed in completion, plastics start by pouring
Mouth is injected in the die cavity.At this time, it is subject to the decorating film position that male and female mould presses, because being persistently subject to come from plastic injection
Urgent power between caused pressure, and male and female mould, and the damage in structure is produced, or even fracture.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of in-mold decoration injection molding mould, can ensure to decorate
The accurate positioning of film, and avoid decorating film from business, between master mold granting excessive oppressive force and be subject to plastic cement to project
During pressure, the damage in structure is caused.
Specifically technical solution is：
In-mold decoration injection molding mould, including upper mold seat and die holder, the lower surface of upper mold seat are installed by upper padding plate
Upper cores, the upper cores are equipped with upper cavity；Injection notch is provided with upper cavity；Pass through lower bolster on corresponding die holder
The lower mode of installation, the lower mode are equipped with lower mode cavity；
The plastic base for needing to spray is clamped by wheel flange, and the wheel flange is connected with the first rotary sleeve；Described
First rotary sleeve is installed in first rotating shaft, and is rotated around first rotating shaft；The first bullet is also equipped with the first rotating shaft
Spring, first spring are located at below the first rotary sleeve；Corresponding clamping ring recess is provided with the lower mode.
Preferable design, further includes the second shaft, second spring, the second spring is cased with second shaft
Top is provided with the second rotary sleeve, and slot is provided with second rotary sleeve；Further include locating rod, the positioning
Bar one end is fixed on wheel flange, when wheel flange is located above lower mode cavity, and plastic base is positioned, the locating rod
The other end is inserted into the slot of second rotary sleeve；Corresponding positioning rod slot is provided with the lower mode.
In-mold decoration injection molding mould provided by the utility model, is accurately positioned by wheel flange, therefore on
Die holder and die holder be not required it is excessive press, therefore ejection formation material will not be subject to excessive pressure and damage.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the utility model.
Embodiment
It is described in conjunction with the embodiments specific embodiment of the present utility model.
As shown in Figure 1, in-mold decoration injection molding mould, including upper mold seat 1 and die holder 14, the lower surface of upper mold seat 1
Upper cores 3 are installed by upper padding plate 2, the upper cores 3 are equipped with upper cavity 4；It is provided with upper cavity 4 and projects notch 5；It is corresponding
Die holder 14 on lower mode 9 installed by lower bolster 13, the lower mode 9 is equipped with lower mode cavity 10；
The plastic base 6 for needing to spray is clamped by wheel flange 8, and the wheel flange 8 is connected with the first rotary sleeve 17；Institute
The first rotary sleeve 17 stated is installed in first rotating shaft 15, and is rotated around first rotating shaft 15；In the first rotating shaft 15 also
First spring 16 is installed, first spring 16 is located at the lower section of the first rotary sleeve 17；It is provided with the lower mode 9
Corresponding clamping ring recess 11.Process is that the plastic base 6 for needing to spray is placed on wheel flange 8 first clamps, then
The first rotary sleeve 17 is rotated, wheel flange 8 and the plastic base 6 for needing to spray are transferred to the top of die holder 14, and under
Die cavity 10 is positioned, and after positioning, 1 downlink of upper mold seat, upper cavity 4 is pressed in the upper surface for the plastic base 6 for needing to spray first,
And leave jet space between 6 upper surface of plastic base with needing to spray；The plastic base 6 one that upper mold seat 1, needs spray
