Beneficial effect: a kind of inner core pulling slide block mechanism that the present invention adopts technique scheme to provide and mould thereof, product needed at front mould inner side core-pulling time, overcome mould structure complexity and Mould Machining difficulty that design front mould pitched roof mechanism brings, the front mould inner side core-pulling of product can be realized, the demoulding quality of effective guarantee product, meanwhile, effectively can reduce the design difficulty of mould, reduce mould and manufacture cost and product injection moulding cost; Mechanism and mould structure design are reasonable, compact conformation, and working stability is safe and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of inner core pulling slide block mechanism of the present invention and mould structure composition schematic diagram thereof;
Fig. 2 is that a kind of inner core pulling slide block mechanism of the present invention and mould thereof are installed and operating diagram on mould.
Detailed description of the invention
Fig. 1-2 is depicted as related description figure of the present invention; A kind of inner core pulling slide block mechanism and mould thereof, comprise pull bar screw 1, pull-rod spring 2, briquetting 3, sliding block spring 4, slide block pull bar screw 5, slide body 6, as shown in Figure 1.
Described slide body 6 is designed with T-slot, for the slide-and-guide of slide body 6; Slide body 6 is designed with inclined-plane, for locking positioning;
Described slide body 6 is provided with slide block pull bar screw 5 and plays the effect of skid Stroke Control, and sliding block spring 4 is installed on slide block pull bar screw 5, for slide body 6 provides motion-promotion force;
Described briquetting 3 is installed in mould template block slots, and briquetting 3 can move in block slots;
Described pull bar screw 1 is installed on briquetting 3 through template screw, and it is provided with the pull-rod spring 2 after compression, pull-rod spring 2 relies on mould template, by pull bar screw 1 for briquetting 3 provides motion-promotion force;
Described briquetting 3 lower end is designed for double inclined plane.
Further, illustrate for ease of operation principle of the present invention, the mould mating parts that Fig. 2 need point out comprises upper clamping plate 7, intermediate plate 8, impression bolster 9, die cavity mold insert 10, core mold insert 11, core fixing plate 12, cushion block 13, thimble cover plate 14, thimble push plate 15, counterdie seat board 16; PL1 opens die joint mould first time, and PL2 is that mould second time opens die joint; Slide body 6 is installed on core mold insert 11 by T-slot shown in Fig. 2, and slide block pull bar screw 5 connects through postive stop baffle with holes on core mold insert 11 and slide body 6; Impression bolster 9, die cavity mold insert 10 offer the slot of moving for briquetting 3; Pull bar screw 1 is installed on briquetting 3 through template impression bolster 9 screw, and it is provided with the pull-rod spring 2 after compression, pull-rod spring 2 relies on mould template impression bolster 9, by pull bar screw 1 for briquetting 3 provides motion-promotion force; The via hole passed through for pull bar screw 1, pull-rod spring 2 is designed with in intermediate plate 8.
During real work, as shown in Figure 2, its motion operation principle is as follows:
1) injection moulding of product cavity side inner reverse fastener side core-pulling demoulding mould die cavity completes, mould starts to open, under the pulling of injection machine push rod, mould dynamic model part is progressively separated with cover half part, now, under the effect of mould spacing controlling organization, mould first time opens and opens at PL1 die joint place, and PL2 die joint then remains closed and is not separated; In Fig. 2, upper clamping plate 7, intermediate plate 8 fixedly stay with injection machine cover half on motionless, pull bar screw 1, pull-rod spring 2, briquetting 3, sliding block spring 4, slide block pull bar screw 5, slide body 6, impression bolster 9, die cavity mold insert 10, core mold insert 11, core fixing plate 12, cushion block 13, thimble cover plate 14, thimble push plate 15, counterdie seat board 16 move down; Pull bar screw 1 will lose the barrier force of upper clamping plate 7, thus, pull-rod spring 2 has the bounce withstanding screw 1 head, press against screw 1 and be adjacent to upper clamping plate 7, conversely, be then that impression bolster 9 is pushed away downwards, and briquetting 3 and screw 1 are screw thread fixed connection, thus, briquetting 3 will be hauled the pressuring action progressively lost slide body 6 by screw 1; Once the thrust on the right side of slide body 6 on inclined-plane progressively loses, the side core-pulling that promotion slide body 6 does to the right along T-slot moves by sliding block spring 4, until the core_pulling demoulding at back-off position on product completes, slide block pull bar screw 5 is blocked by the baffle plate that slide body 6 designs, limit its action of loosing core to the right, thus reach the object of the product cover half side inside block side core-pulling demoulding;
2) the ejecting of product
After product cavity side inner reverse fastener side core-pulling stripping action completes, under the effect of mould spacing controlling organization, mould first time opens and opens at PL2 die joint place, thus under the ejecting of mould-ejecting plate thimble cover plate 14, thimble push plate 15 and die ejector pin, product is ejected from die cavity mold insert 10, completes the demoulding of whole product;
3) when resetting, contrary with product ejection process, under the effect of mould spacing controlling organization, mould present PL2 die joint place closes, and then closed at PL1 die joint place, will press against screw 1 pair of pull-rod spring 2 compress by upper clamping plate 7, simultaneously, slide body 6 is pushed back reset by promotion briquetting 3 by screw 1, and mould closes, and waits for that next injection cycle starts.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
