Specific embodiment
The production technology of annex is directly molded on the utility model fiberboard, and fiberboard is first hot-forming on mould to be become
Product, then drills on the fiberboard of shaping, and the one side that the fiberboard of shaping intends being molded annex is placed on injection then
In die cavity, be molded toward in injection die cavities by drilling, that is, complete annex 8 is molded on fiberboard.
Hot-forming in order to be conducive to, above-mentioned fiberboard is by mestha, jute or wood-fibred etc. sponge and PP
Material is mixed.
For improve production efficiency, it is directly entered in injection die cavities after above-mentioned fiberboard is hot-forming and is molded.Using
This mode is in the case where production line is allowed, it is not necessary to is detained or moves fiberboard, and can save follow-up injection needs to preheat
The step of fiberboard.
If cannot realize being directly entered injection step, then the hot-forming fiberboard for having cooled down needs first to preheat 6-10
Enter back in injection die cavities after minute and be molded, preheating temperature is 70 ~ 120 degree, it is advantageously ensured that noting after injection after first preheating
It is more firm that modeling annex is connected with fiberboard.
In order that connection is firm, above-mentioned bore position is located on the position of injection annex, and above-mentioned drilling is shoulder hole or cone
The big nose end of shape hole, shoulder hole or bellmouth is located on the one side of injection annex opposite to each other, using setting for shoulder hole or bellmouth
Meter so that having in shoulder hole or bellmouth so that injection annex with
The bonding strength of fiberboard is significantly improved, and bonding strength improves more than 3 times, the diameter control of above-mentioned drilling or perforation 0.6 ~
The end diameter of 1.5mm, a diameter of shoulder hole or bellmouth.The taper of bellmouth is 100 degree.
Further, in injection, the pressure being pressed against in injection die cavities is applied with fiberboard, the pressure is conjunction
Molding pressure, more than tens of tonnes of pressure, to avoid flash.
Further, in injection, the injection rate of plastic material is 0.6 kilogram per second.
The above-mentioned material for being molded can be the thermoplastics such as PP, PA, ABS, PC, and add in above material
