Description
Technical field
Patent of the present invention relates to injection mold side core-pulling technical field, especially relates to a kind of Angle Pin side core-drawing mechanism.
Background technology
During injection mo(u)lding, while having with the inconsistent interior apertura lateralis of die sinking direction or the structure such as side is recessed, for ease of the smooth demoulding of plastic, undercut core-pulling mechanism must be set on plastic.Common side core-drawing mechanism has Angle Pin side core-drawing mechanism, curved pin side core-drawing mechanism, oblique chute side core-drawing mechanism, angled-lift splits side core-drawing mechanism and rack-and-pinion side core-drawing mechanism etc.Wherein, Angle Pin side core-drawing mechanism is the most frequently used a kind of undercut core-pulling mechanism.Its structure is generally comprised of Angle Pin, side core slide block, slide block positioning device and locking device etc.
But for the large-angle inclined small-sized injecting products to loosing core of the long distance of needs, because side core is elongated and the angle of loosing core is larger, while adopting common Angle Pin side core-drawing mechanism to loose core, there will be the phenomenons such as side core location and installation is inaccurate, side core damages and the demoulding is difficult, damage plastic, therefore, must a kind of Angle Pin side core-drawing mechanism of exploitation.
Summary of the invention
For oblique small-sized core length, apart from the side core existing in side core-pulling process, the problems such as positioning precision is not high, the demoulding is difficult are installed, the invention provides a kind of Angle Pin side core-drawing mechanism, thereby optimization mould structure, improves the mould accuracy of manufacture and injecting products quality.
The technical solution adopted in the present invention is: a kind of Angle Pin side core-drawing mechanism, comprise side core assembly, slide block assembly, Angle Pin, described side core assembly comprises side core, the side core cover for fixation side core, little spring, packing ring and core pressing plate, described slide block assembly comprises slide block mold insert, mold insert briquetting, core pressing plate and slide block, slide block mold insert is set in described slide block, described mold insert briquetting is fixed on slide block mold insert on slide block, and described little spring, packing ring and core pressing plate are fixed on side core on described slide block mold insert.
Further, described Angle Pin side core-drawing mechanism also comprises big spring, oblique block, support and screw, and described oblique block is fixed by screws on described support, the position of the oblique movement of assurance mechanism and slide block work.
Further, described Angle Pin top is provided with Angle Pin pressing plate, and described Angle Pin pressing plate is fixed by screw, and described Angle Pin is compressed by pressing plate briquetting.
Further, between described slide block and Angle Pin pressing plate, be provided with wedge block, described wedge block is fixed by screw.
Beneficial effect of the present invention is:
(1) adopt the structure of built-in side core cover, by little spring, packing ring and core pressing plate etc., side core is fixed on slide block mold insert, while guaranteeing slide block action, side core moves with side core cover and slide block mold insert.
(2) adopt the slide block combination of built-in sliding block mold insert, rationally solved the location and installation problem of side core and slide block, make the accurate positionings such as slide block mold insert and side core, motion is reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.

Fig. 2 is side core assembly schematic diagram of the present invention;
Fig. 3 is slide block assembly schematic diagram of the present invention.
In figure: 1-side core cover, 2-side core, 3-little spring, 4-slide block mold insert, 5-mold insert briquetting, 6-packing ring, 7-core pressing plate, 8-slide block, 9-Angle Pin, 10-pressing plate briquetting, 11-Angle Pin pressing plate, 12-screw, 13-wedge block, 14-screw, 15-screw, 16-big spring, the oblique block of 17-, 18-screw, 19-support.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of Angle Pin side core-drawing mechanism as shown in Figure 1 to Figure 3, comprise side core assembly, slide block assembly, Angle Pin, described side core assembly comprises side core 2, for side core cover 1, little spring 3, packing ring 6 and the core pressing plate 7 of fixation side core 2, described slide block assembly comprises slide block mold insert 4, mold insert briquetting 5, core pressing plate 7 and slide block 8, in described slide block 8, slide block mold insert 4 is set, described mold insert briquetting 5 is fixed on slide block mold insert 4 on slide block 8, and described little spring 3, packing ring 6 and core pressing plate 7 are fixed on side core 2 on described slide block mold insert 4.
As the further embodiment of the present invention, described Angle Pin side core-drawing mechanism also comprises big spring 16, oblique block 17, support 19 and screw 18, and described oblique block 17 is fixed on described support 17 by screw 18.
As the further embodiment of the present invention, described Angle Pin 9 tops are provided with Angle Pin pressing plate 11, and described Angle Pin pressing plate 11 is fixed by screw 12, and described Angle Pin 9 is compressed by pressing plate briquetting 10.
As the further embodiment of the present invention, between described slide block 8 and Angle Pin pressing plate 11, be provided with wedge block 13, described wedge block 13 is fixed by screw 14.
The present invention is by the reasonable combination of a plurality of parts such as slide block mold insert, side core cover, little spring, tilted supporter, successfully solve large-angle inclined moulding and the demoulding difficult problem to loosing core of the long distance of small-sized injecting products, conscientiously improved the accuracy of manufacture and the injecting products quality of mould.
The course of work of this mechanism is: during die sinking, mould opening force acts on slide block by Angle Pin, forces slide block guide runner along dynamic model when die sinking starts outwards to slide.Meanwhile, little spring forces side core, side core cover and slide block mold insert to be combined closely, and the action of guaranteeing to loose core is accurate.Slide block positioning device is limited in slide block the position of loosing core and ending, and Angle Pin can insert in the inclined hole of slide block when guaranteeing matched moulds, and slide block is resetted smoothly.
