Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in figure 1, a kind of core pulling positioning mechanism for mould, including side core component 1, in the present embodiment, side Core package 1 is installed in the cover half in die holder（Do not illustrated in figure）.Side core component 1 includes core pulling mold insert 2, core pulling mold insert 2 front end has forming ends 21, forming ends 21 and die cavity in die holder（Do not illustrated in figure）Coordinate, so as to shaped article, at this In embodiment, product is the light-strip at automobile lampshade（Do not illustrated in figure）.

With reference to shown in Fig. 2, forming ends 21 is obliquely installed in the front end of core pulling mold insert 2, the mould with formed light conductive bar in die holder Chamber matches, and adjusts the space-consuming of shaping mold cavity, improves space availability ratio, so as to the die holder from small volume.Into The front end of type end 21 has one-level boss 211, and the end face of one-level boss 211 is Irregular Boundary Surface, and one-level boss 211 is matched somebody with somebody with die cavity Close, for the hole in formed light conductive bar.The side wall of one-level boss 211 has a longitudinally disposed one-level forming tank 212, one-level into The boss that type groove 212 is used in the side wall of formed light conductive bar hole.There are two level boss 213, and two positioned at the top of one-level boss 211 The height of level boss 213 is less than the height of one-level boss 211, and two level boss 213 coordinates with die cavity, for formed light conductive bar mesopore The groove of top.The side wall of two level boss 213 has a two level forming tank 214, and it is recessed that two level forming tank 214 is used for formed light conductive bar Boss in groove.

Have cooperatively form first to determine shown in reference picture 1, Fig. 3 and Fig. 4, between the dynamic model in core pulling mold insert 2 and die holder Position mechanism 5a.First detent mechanism 5a includes a first wedge block 6a, and the first wedge block 6a one end and dynamic model are fixed, separately The trapezoidal boss-shaped in one end.The upper surface of the rear end of core pulling mold insert 2 offers the first positioning hole 22, when dynamic model and cover half matched moulds, First wedge block 6a inserts in the first positioning hole 22 positioning for realizing core pulling mold insert 2 and dynamic model, and core pulling mold insert 2 is produced by dynamic model Raw position-limiting action, prevents core pulling mold insert 2 from retreating.

The trailing flank of the rear end of core pulling mold insert 2 has a cavity, is embedded with a STATEMENT OF FEDERALLY SPONSORED 3 in cavity, after STATEMENT OF FEDERALLY SPONSORED 3 Side is fixedly connected with a drive mechanism 4, and in the present embodiment, drive mechanism 4 is hydraulic-driven.There is one in STATEMENT OF FEDERALLY SPONSORED 3 The through hole laterally set, the second fixture block 7 of a waist type shape is inserted in the through hole, core pulling mold insert 2, which is located at cavity, to be offered For the second limit card slot 23 of the second fixture block 7 placement, the second fixture block 7 horizontal sliding in the second limit card slot 23, and work as second When fixture block 7 slides onto the second 23 end of limit card slot, you can drive core pulling mold insert 2 to be slided with STATEMENT OF FEDERALLY SPONSORED 3 is synchronous in cover half.Take out The upper surface of the rear end of core mold insert 2 has a through hole communicated with cavity, and a support rod 8 is installed with the through hole, is supported The direction that the vertical STATEMENT OF FEDERALLY SPONSORED 3 of bar 8 slides is set, and the lower end of support rod 8 contradicts the upper surface of STATEMENT OF FEDERALLY SPONSORED 3 all the time, when STATEMENT OF FEDERALLY SPONSORED 3 exists When being moved in cavity to extraction direction, because the volume that STATEMENT OF FEDERALLY SPONSORED 3 is placed in cavity is gradually reduced so that can be produced in slipping A raw moment of torsion loosens, the loosening for being provided for limiting when STATEMENT OF FEDERALLY SPONSORED 3 slides of support rod 8.

There is the second detent mechanism 5b cooperatively formed with reference to shown in Fig. 5, between the cover half in STATEMENT OF FEDERALLY SPONSORED 3 and die holder.The Two detent mechanism 5b include a locating piece 9, and locating piece 9 is fixedly installed at the track that side core component 1 slides in cover half, and The longitudinal direction of locating piece 9 offers second positioning hole 91.The underside of STATEMENT OF FEDERALLY SPONSORED 3 is provided with a second wedge block 6b, core pulling Mold insert 2, which is located at cavity, longitudinally offers a spacing hole 24, and the second wedge block 6b wears spacing hole 24 until insertion second Positioning hole 91, so as to realize the positioning of STATEMENT OF FEDERALLY SPONSORED 3 and cover half.The downside of STATEMENT OF FEDERALLY SPONSORED 3 offers first along the glide direction of STATEMENT OF FEDERALLY SPONSORED 3 Limit card slot 31, the first wedge block 6a one end have the first fixture block 6b1 with the clamping of the first limit card slot 31, and the first fixture block 6b1 slides in the first limit card slot 31, and the first fixture block 6b1 and the longitudinal section of the first limit card slot 31 are in T shape.First limit The front end of position neck 31 is set diagonally downward along the glide direction of STATEMENT OF FEDERALLY SPONSORED 3 from cavity inside to cavities open direction, and the first limit The both ends of position neck 31 all extend to the both ends of STATEMENT OF FEDERALLY SPONSORED 3, when STATEMENT OF FEDERALLY SPONSORED 3 is moved in cavity to direction of insertion, because of first Fixture block 6b1 and the first limit card slot 31 limitation, the first fixture block 6b1 drive whole second wedge block 6b done in spacing hole 24 to Lower linear motion, so that in the second positioning hole 91 of the second wedge block 6b insertion locating pieces 9, STATEMENT OF FEDERALLY SPONSORED 3 is produced by cover half Raw position-limiting action, prevents STATEMENT OF FEDERALLY SPONSORED 3 from retreating.

During using the utility model, when die holder matched moulds, drive mechanism 4 drive STATEMENT OF FEDERALLY SPONSORED 3 in the cavity of core pulling mold insert 2 to Direction of insertion is moved, and now the second wedge block 6b is moved downward in spacing hole 24, when STATEMENT OF FEDERALLY SPONSORED 3 drive core pulling mold insert 2 into During type desired position, in the second positioning hole 91 of the second wedge block 6b insertion locating pieces 9, while the first wedge block at dynamic model In first positioning hole 22 of 6a insertion core pullings mold insert 2, now side core component 1 is through the first detent mechanism 5a and the second detent mechanism 5b's is spacing, effectively prevents side core component 1 from retreating；When die holder molds, the first wedge block 6a separates with core pulling mold insert 2, drives Mechanism 4 drives STATEMENT OF FEDERALLY SPONSORED 3 to be moved in the cavity of core pulling mold insert 2 to extraction direction, and STATEMENT OF FEDERALLY SPONSORED 3 drives the second wedge block 6b limiting Motion with locating piece 9 until depart from upwards in the block of position, and now side core component 1 can move to the direction away from light-strip, so as to It is easy to light-strip to be stripped.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
