Details are as follows for the course of work of mobile phone shell injection mold of the present invention.
Fig. 1 is the state after mobile phone shell injection mold of the present invention die sinking, and now, mobile phone shell is ejected, and male model plate 10 is away from caster 20, and male model plate 10 and fixed head 36, scraping wings 45 and heat flux plates 44, caster 20 and scraping wings 45 are in separated position.Correspondingly, first tiltedly stretches the tip 111 and second and tiltedly stretches the tip 115 and all from first, dodge hole 212 and second respectively and dodge hole 216 and depart from.
Put into after hot pressing product, through scraping wings and heat flux plates, close close, caster and scraping wings close and close after operation, under the acting in conjunction of thimble and top roller, male model plate and caster start to close and close, the state after male model plate and caster close and close as shown in Figure 2.Referring to Fig. 2, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and is inserted into respectively first and dodges hole 212 and second and dodge in hole 216.Owing to dodging hole, be oblique, drive thus the first slide block 211 and the second slide block 215 to slide to die cavity direction.Meanwhile, the first spring 213 and the second spring 217 are in compressive state.The 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 model plate and caster close and close, under the effect of top roller, fixed head moves upward and closes and close with male model plate.Fig. 3 is that mobile phone shell injection mold of the present invention closes the partial structurtes schematic diagram of the state of closing in male model plate and fixed head, as shown in Figure 3, now, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and continues respectively to dodge hole 212 and second to first and dodge hole 216 and stretch into, stretching in process continues to drive the first slide block 211 and the second slide block 215 to slide to die cavity, until first projection the 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 moves upward and arrives at the inwall of mobile phone shell and the second barb 114 is outwards pushed with the back-off of the mobile phone shell other end and coincide.
Male model plate and fixed head close and close rear beginning injection moulding, pressurize and refrigerating work procedure, injection moulding, pressurize and cooling after, scraping wings successively separates with heat flux plates and caster, under the effect of thimble, male model plate separates with fixed head subsequently.Fig. 4 is the partial structurtes schematic diagram of mobile phone shell injection mold of the present invention in male model plate and fixed head released state, as shown in Figure 4, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and from first, dodges hole 212 and second respectively and dodge hole 216 and exit, the first spring 213 and the second spring 217 are because the pressure being subject to reduces and partial reset, thereby drive the first slide block 211 and the second slide block 215 away from die cavity, the first projection 214 is separated with mobile phone shell two ends with the second projection 218.Voussoir 112 moves downward, the extruding of the second barb 114 eliminated, and separated due to the second projection 218 and mobile phone shell end simultaneously, the second barb 114 is removed and the coincideing of mobile phone shell back-off.
Fig. 5 is the partial structurtes schematic diagram of mobile phone shell injection mold of the present invention in male model plate and caster released state, under the effect of thimble, first tiltedly stretches the tip 111 and second tiltedly stretches the tip 115 and from first, dodges hole 212 and second completely respectively and dodge hole 216 and exit, the pressure that the first spring 213 and the second spring 217 are subject to disappears and resets completely, thereby drives the first slide block 211 and the second slide block 215 to reset.
After male model plate is separated with caster, the top roller jack-up that makes progress, thus push rod ejects the first barb finished product is ejected, and after finished product ejects, takes away.
Mobile phone shell injection mold of the present invention, by the avoiding mechanism cooperatively interacting is set on male model plate and caster, make the injection molding at mobile phone shell back-off position become feasible simple, and die sinking operation of the present invention is simple, directly, by the just energy die sinking that ejects of 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 is equal to replacement, all should be encompassed in the middle of the protection domain of the claims in the present invention.
