Abstract
The invention discloses a kind of injection moulding encapsulation methods, wherein, comprise the steps: 1) injection machine, PPSU, injection mold, liquid-state silicon gel, encapsulation die are provided; 2) with injection machine, PPSU is warmed to 350 DEG C to 400 DEG C, injects in the die cavity of injection mold after realizing plasticizing, after shaping, take out to obtain PPSU shaped piece; 4) PPSU shaped piece is put into the die cavity of encapsulation die and encapsulation die of heating to 150 DEG C to 200 DEG C, then in the die cavity with injection machine liquid-state silicon gel being injected encapsulation die, encapsulate is carried out to PPSU shaped piece, in the process, liquid-state silicon gel can complete a sulfuration at the temperature of 150 DEG C to 200 DEG C, takes out to obtain silica gel bag PPSU goods after shaping.Compared to existing technology, the present invention is simple to operate, gained finished product safe and sanitary, good looking appearance, comfortable feel, and high temperature-resistant disinfected.
Description
Technical field
The present invention relates to a kind of injection moulding encapsulation methods.
Background technology
Because country is allowed for the plastics that infant article is produced, as PP, PE, ABS, PS etc., its heat distortion temperature is all much lower than silica gel forming temperature, so these materials can not use silica gel secondary injection molding, so, need a kind of product at present badly and fill up this blank.
Summary of the invention
In view of this, technical problem to be solved by this invention is: provide a kind of simple to operate, injection moulding encapsulation methods that can obtain attractive in appearance, the comfortable feel goods of safety.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
A kind of injection moulding encapsulation methods, wherein, comprises the steps:
1) injection machine, PPSU, injection mold, liquid-state silicon gel, encapsulation die are provided;
2) with injection machine, PPSU is warmed to 350 DEG C to 400 DEG C, injects in the die cavity of injection mold after realizing plasticizing, after shaping, take out to obtain PPSU shaped piece;
4) PPSU shaped piece is put into the die cavity of encapsulation die and encapsulation die of heating to 150 DEG C to 200 DEG C, then in the die cavity with injection machine liquid-state silicon gel being injected encapsulation die, encapsulate is carried out to PPSU shaped piece, in the process, liquid-state silicon gel can complete a sulfuration at the temperature of 150 DEG C to 200 DEG C, takes out to obtain silica gel bag PPSU goods after shaping;
As preferably, described step 2) and step 4) between also in steps 3), described step 3) for carry out adhesive spraying to PPSU shaped piece surface and to dry.
As preferably, described step 4) after also comprise step 5), described step 5) for providing vulcanizing oven and described silica gel bag PPSU goods being put into the vulcanizing oven post-cure of 150 DEG C to 200 DEG C.
As shown from the above technical solution, the invention has the beneficial effects as follows:
Compared to existing technology, the present invention is simple to operate, gained finished product safe and sanitary, good looking appearance, comfortable feel, and high temperature-resistant disinfected.Specifically, PPSU is high new plastic, and safe and sanitary, forming temperature are higher than silica gel, can overcome forming temperature difference between other materials and cause the technical problem of the aspects such as distortion, fusing, so can be integrated with silica gel injection moulding encapsulate.Through the silica gel bag PPSU finished product that the inventive method is obtained, for feeding bottle, because being surrounded by the silica gel of one deck super-low-hardness outside bottle, there is the flexibility of bionical parent, so its feel and practicality are better, aesthetic property is stronger, class is also aobvious higher, there is very high economic worth and social value.
