Details are as follows for the course of work of Plastic injection mould for mobile phone shell of the present invention.
Fig. 1 is the state after Plastic injection mould for mobile phone shell die sinking of the present invention, and now, mobile phone shell is ejected, and male template 10 is away from caster 20, and male template 10 is in separated position with heat flux plates 44, caster 20 with scraping wings 45 with fixed head 36, scraping wings 45.Correspondingly, first tiltedly stretches the tip 111 and second and tiltedly stretches the tip 115 and dodge hole 212 and second from first all respectively and dodge hole 216 and depart from.
After putting into hot pressing product, close through scraping wings and heat flux plates close, after caster and scraping wings close and close operation, under the acting in conjunction of thimble and top roller, male template and caster start conjunction and close, and male template and caster close the state after closing as shown in Figure 2.See Fig. 2, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and is inserted into first respectively and dodges hole 212 and second and dodge in hole 216.Be oblique owing to dodging hole, drive the first slide block 211 and the second slide block 215 to slide to die cavity direction thus.Meanwhile, the first spring 213 and the second spring 217 are in compressive state.First barb 113 stretches into die cavity and inserts the back-off of mobile phone shell one end, and the second barb 114 stretches into die cavity, and the inwall of mobile phone shell is arrived in its upper end.
After male template and caster close and close, under the effect of top roller, fixed head moves upward to close with male template and closes.Fig. 3 is the partial structurtes schematic diagram that Plastic injection mould for mobile phone shell of the present invention is in that male template and fixed head close state of closing, as shown in Figure 3, now, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and continues to dodge hole 212 and second respectively to first and dodge hole 216 and stretch into, stretch in process and continue drive first slide block 211 and the second slide block 215 slides to die cavity, until the first protruding 214 and second projection 218 respectively with the end fit of mobile phone shell, and the first spring 213 and the second spring 217 are also further compressed.Under top roller effect, voussoir 112 move upward the inwall that arrives at mobile phone shell and by the second barb 114 outwards extruding coincide with the back-off of the mobile phone shell other end.
Male template and fixed head close and close rear beginning injection moulding, pressurize and refrigerating work procedure, and after injection moulding, pressurize and cooling, scraping wings successively separates with heat flux plates and caster, and subsequently under the effect of thimble, male template is separated with fixed head.Fig. 4 is the partial structurtes schematic diagram that Plastic injection mould for mobile phone shell of the present invention is in male template and fixed head released state, as shown in Figure 4, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and dodges hole 212 and second from first respectively and dodge hole 216 and exit, first spring 213 and the second spring 217 be partial reset due to the pressure reduction be subject to, thus drive the first slide block 211 and the second slide block 215 away from die cavity, first protruding 214 is separated with mobile phone shell two ends with the second projection 218.Voussoir 112 moves downward, and eliminates the extruding of the second barb 114, being separated simultaneously due to the second projection 218 and mobile phone shell end, and the second barb 114 is removed and the coincideing of mobile phone shell back-off.
Fig. 5 is the partial structurtes schematic diagram that Plastic injection mould for mobile phone shell of the present invention is in male template and caster released state, under the effect of thimble, first tiltedly stretches the tip 111 and second tiltedly stretches that the tip 115 is complete respectively dodges hole 212 and second from first and dodge hole 216 and exit, the distress resolves that first spring 213 and the second spring 217 are subject to and resetting completely, thus drive the first slide block 211 and the second slide block 215 to reset.
After male template is separated with caster, top roller is jack-up upwards, and the first barb ejects thus ejected by finished product by push rod, takes away after finished product ejects.
Plastic injection mould for mobile phone shell of the present invention, by arranging the avoiding mechanism cooperatively interacted in male template and caster, make the injection molding at mobile phone shell back-off position become simply feasible, and die sinking operation of the present invention is simple, ejecting with regard to energy die sinking directly by thimble, working (machining) efficiency is high.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
