In view of this, be necessary to provide a kind of mold insert detent mechanism, this mold insert detent mechanism can solve the low problem of mold insert locating surface existing in above-mentioned technology in fact.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of mold insert detent mechanism, this mold insert detent mechanism can solve the low problem of above-mentioned mold insert locating surface.
In order to achieve the above object, mold insert detent mechanism of the present invention, it is applied in mould, and this mould comprises the die cavity of a male model plate, a caster and the hollow being made up of male die core and mother module core, and this mold insert detent mechanism comprises:
One locates into son, its one end is placed in described die cavity and this end contacts with described mother module core, this is located, and the sub-other end is placed in described male die core and this end contacts with described male model plate, this male model plate is provided with a sliding tray, and this sliding tray is for placing described this end contacting with male model plate into son of locating; And
One flexible member, it is located in described male model plate, in this male model plate, is provided with an avoiding hollow groove, and this avoiding hollow groove is used for placing described flexible member, and this flexible member one end contacts with described location into son.
Preferably, describedly locate this end that son is placed in sliding tray and be inverted T-shaped.
Preferably, described flexible member in the time of mould matched moulds in compressive state.
Preferably, described flexible member is a spring.
Compared to prior art, mold insert detent mechanism of the present invention, by a flexible member is set in male model plate, and this flexible member with locate into son inconsistent, in the time of mould die sinking, locate into son and start the direction motion toward mother module core owing to being subject to the elastic force effect of flexible member, mold insert locating surface is raise.
[accompanying drawing explanation]
Fig. 1 illustrates the generalized section of prior art.
Generalized section when Fig. 2 illustrates the die sinking for the first time of mold insert detent mechanism of the present invention.
Generalized section when Fig. 3 illustrates the matched moulds of mold insert detent mechanism of the present invention.
Generalized section when Fig. 4 illustrates the die sinking for the second time of mold insert detent mechanism of the present invention.
[specific embodiment]
Consult shown in Fig. 2, Fig. 3 and Fig. 4, generalized section when wherein Fig. 2 is the die sinking for the first time of mold insert 108 detent mechanisms of the present invention, generalized section when Fig. 3 is the matched moulds of mold insert 108 detent mechanisms of the present invention, generalized section when Fig. 4 is the die sinking for the second time of mold insert 108 detent mechanisms of the present invention.
Mold insert 108 detent mechanisms of the present invention, it is applied in mould, and this mould comprises the die cavity 103 of a male model plate 102, a caster (not shown) and the hollow being made up of male die core 101 and mother module core 100, in the present embodiment, refer to Fig. 2, these mold insert 108 detent mechanisms comprise:
One locates into son 104, this is located sub 104 one end and is placed in described die cavity 103 and this end for placing mold insert 108, locate sub 104 other ends and be placed in described male die core 101, in the time of mould matched moulds, refer to Fig. 3, described son 104 these ends that are placed in die cavity 103 of locating contact with described mother module core 100, and locating son 104 these ends that are placed in male die core 101 contacts with described male model plate 102, this male model plate 102 is provided with a sliding tray 105, and this sliding tray 105 is for placing described location into son 104 these ends that contact with male model plate 102; And
One flexible member 106, this flexible member 106 is located in described male model plate 102, is provided with an avoiding hollow groove 107 in this male model plate 102, and this avoiding hollow groove 107 is for placing described flexible member 106, and these flexible member 106 one end contact with described location into son 104.
Wherein, described son 104 these ends that are placed in sliding tray 105 of locating are inverted T-shaped, and in the time of mould die sinking, this sliding tray 105 provides mobile space for locating into son 104.
Wherein, described flexible member 106 is in compressive state in the time of mould matched moulds, and in the present embodiment, this flexible member 106 is a spring.
In the present embodiment, refer to Fig. 2, in the time of mould die sinking for the first time, due to flexible member 106 when the mould matched moulds in compressive state, so locate into the son 104 elastic force effects that are subject to flexible member 106 and start the direction motion toward mother module core 100, the locating surface of mold insert 108 raises, and then, mold insert 108 is inserted into the location that is placed in die cavity 103 quickly and accurately and enters on son 104.
In the present embodiment, refer to Fig. 3, process when mould matched moulds is: male die core 101 drives to locate into son 104 and moves toward the direction of mother module core 100 simultaneously, in motion process, locate into son 104 and contact with mother module core 100, because male die core 101 continues the direction motion toward mother module core 100, locate into son 104 reaction forces that are subject to mother module core 100 and start the direction motion toward male model plate 102, flexible member 106 is compressed because locating into the motion of son 104, until the compressive state of flexible member 106 while getting back to last matched moulds, male die core 101 stop motions, then toward the plastic cement of injection moulding melting in die cavity 103, mold insert 108 combines with the plastic cement of melting, in the time that filling, die cavity 103 stops injecting plastic cement, mold insert 108 is integrated with plastic rubber shaping, product 109 moulding complete.
In the present embodiment, refer to Fig. 4, after product 109 moulding complete, mould starts die sinking for the second time, and male die core 101 is toward the direction motion away from mother module core 100, because flexible member 106 is in compressive state, locate into the son 104 elastic force effects that are subject to flexible member 106 and start the direction motion toward mother module core 100, take out shaped article 109, the course of work while then getting back to die sinking for the first time, starts injection molding product 109 next time.
Compared to prior art, mold insert 108 detent mechanisms of the present invention, by at the interior flexible member 106 that arranges of male model plate 102, and this flexible member 106 with locate into son 104 inconsistent, in the time of mould die sinking, locate into son 104 and start the direction motion toward mother module core 100 owing to being subject to the elastic force effect of flexible member 106, so that the locating surface of mold insert 108 raises.
