Embodiment
The embodiment of the present invention is described in more detail below in conjunction with the accompanying drawings.
Referring to figs. 1 to Fig. 3, a kind of insert molding die of the present embodiment, including quiet membrane module 10, dynamic model component 20 and push rod
30, quiet membrane module 10 includes the main insert 11 of quiet mould, and mold cavity 111 is located in the main insert 11 of quiet mould, also includes quiet module certainly
The general quiet template of part, hot runner manifold, top plate, hot runner manifold etc., are fixedly connected between each part by screw, by guide pillar slide guide mould
The plate direction of motion；Dynamic model component 20 includes the main insert 21 of dynamic model, and mold cores 211, diaphragm locating dowel 212 and push rod 30 are positioned at dynamic
In the main insert 21 of mould, also include the general moving platen of dynamic model component, liftout plate, mould leg plate, bottom plate etc. certainly, between each part by
Screw is fixedly connected, by the guide pillar slide guide template direction of motion.Because the improvement of quiet membrane module 10 is mainly concerned with its quiet main edge of mould
On block 11, the improvement of dynamic model component 20 is mainly concerned with the main insert 21 of its dynamic model, then to quiet membrane module 10 and dynamic model component 20
Miscellaneous part structure repeat no more.Unlike the prior art, it is additionally provided with and is located in the quiet main insert 11 of mould in the present embodiment
The many places secondary cavity region 112 of the surrounding of mold cavity 111, secondary cavity region 112 connects with mold cavity 111, and mould enters
Glue mouth 113 is located therein at one in secondary cavity region 112, as shown in figure 3, mold cavity 111 is in approximate long in the present embodiment
Square, secondary cavity 112 has everywhere, is laid in four sides periphery of mold cavity 111, mould glue-feeder 113 is positioned at upper
In the secondary cavity region 112 of side；Diaphragm locating dowel 212 be located in the main insert 21 of dynamic model with wherein one at secondary cavity region
112 corresponding opening positions or in the main insert 21 of dynamic model with wherein one at the corresponding opening position in secondary cavity region 112
Periphery, the opening position corresponding with all secondary cavity regions 112 is corresponding in the main insert 21 of dynamic model is laid with push rod 30.
Injection molding material is allowed steadily to promote by setting secondary cavity region 112 around mold cavity 111, during injection, will be tired
The defects of gas, bubble, can rush to secondary cavity region 112, meanwhile, diaphragm locating dowel 212 and push rod 30 are in the main insert 21 of dynamic model
On position it is corresponding with the position in secondary cavity region 112, mould glue-feeder 113 is located therein secondary cavity region at one
In 112, then avoid the mold cavity region of shaping final products shape, then diaphragm positioning hole left on product,
Ejection vestige and weld mark are respectively positioned on the auxiliary area of product surrounding, can be removed by cutting, not interfered with the surface of product
Quality and outward appearance, ensure final products region without any defect.
Further, because the defects of trapped gas, bubble is typically accumulated in apart from the remote position of mould glue-feeder 113, get over
Easier generation trapped gas, bubble at a distance, and at the place of mould glue-feeder 113 due to the big injection molding material of injection pressure do not allow to be also easy to produce it is tired
Gas, bubble, then the area in the secondary cavity region 112 where mould glue-feeder 113 be less than other secondary cavity regions 112 everywhere
Area, i.e., in the present embodiment, the area in the top secondary cavity region 112 where mould glue-feeder 113 be less than other three
Locate the area in secondary cavity region 112, its area need to only meet that mould glue-feeder 113 can be set.
Further, as shown in Fig. 2 the secondary cavity region 112 at the place of mould glue-feeder 113 and diaphragm locating dowel
Secondary cavity region 112 corresponding to 212 is same secondary cavity region, and the quantity of diaphragm locating dowel 212 is two, auxiliary positioned at this
The left and right sides in die cavity region 112 is helped, diaphragm is hung in two diaphragm locating dowels 212 herein, and diaphragm positioning is located proximate to mould
Have glue-feeder 113, then diaphragm corrugated phenomenon can be avoided as much as when entering glue, ensure the quality of diaphragm back side overlay film.
The present embodiment also proposed a kind of in-mould injection method, and the injection mold of use is to be noted in the mould described in the present embodiment
Mould, comprise the following steps：
1）Mould mold, will be hot-forming after diaphragm 40（As shown in Figure 4）It is placed in the main insert 21 of dynamic model, by the main edge of dynamic model
The positioning of diaphragm locating dowel 212 on block 21 is fixed, and the area of diaphragm 40 is more than the area of mold cavity 111；
2）Mould matched moulds, injection machine are filled by quiet membrane module side from the injecting glue of mould glue-feeder 113 in the main insert 11 of quiet mould, sizing material
Mold cavity 111 and secondary cavity region 112 form plastic product matrix, and diaphragm is coated on the back side of plastic product matrix,
The injecting products 50 of back side overlay film are formed, as shown in Figure 5；
3）Mould molds, and the injecting products 50 after the overlay film of the back side is removed from the main insert 21 of dynamic model, as shown in figure 5, the product back side
Circular vestige on each part corresponding with mold cavity region is push rod vestige, diaphragm locating dowel vestige, and line style vestige is molten
Lapping defect, thus scheme to can be seen that with reference to Fig. 6 and Fig. 7, such vestige does not influence the surface quality of final products；
4）Injecting products are post-processed, and part 51 corresponding with secondary cavity region 112 on injecting products 50 is removed（It can pass through
Digit Control Machine Tool working process）, complete injecting products are obtained, as shown in Figure 6 to 8.
As shown in figure 4, diaphragm 40 includes diaphragm body 41 and the extension auxiliary to stretch out in the side of diaphragm body 41 1
Region 42, the positioning hole 43 of diaphragm 40 are located on extension auxiliary area 42, positioning hole 43 and the position pair of diaphragm locating dowel 212
Should, it is arranged on extension auxiliary area 42, can avoids leaving positioning hole vestige on the injecting products diaphragm ultimately formed, ensures
Product quality.The area of diaphragm 40 is more than the area of mold cavity 111, then ensures that diaphragm 40 all covers in product back side overlay film area
Film, avoids producing diaphragm and shows money or valuables one carries unintentionally defect, improves production yield, reduces production cost
The present embodiment also proposed a kind of using injecting product in mold 50 made of above-mentioned in-mould injection method, including transparent modeling
Expect product matrix 51 and the diaphragm 52 on the plastic product matrix back side, as shown in Figure 6 to 8, product diaphragm without showing money or valuables one carries unintentionally and
Other surfaces defect, and diaphragm is located at the product matrix back side, can be adjusted by the thickness of plastic product matrix 51, realize product
Stereoscopic visual effect.
The above described is only a preferred embodiment of the present invention, being not the limitation for making other forms to the present invention, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But it is every without departing from technical solution of the present invention content, the technical spirit according to the present invention is to above example institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection domain of technical solution of the present invention.
