For briquetting provides motion-promotion force.
Preferably, the briquetting lower end is designed for double inclined plane.
Beneficial effect：The present invention uses T-shaped piece that above-mentioned technical proposal is provided to drive and slide core_pulling demoulding outside mechanical side
Mechanism, when product needed is in front mould inner side core-pulling, overcome the mould structure complexity brought of design front mould pitched roof mechanism and
Mould difficulty of processing, can realize the front mould inner side core-pulling of product, and the demoulding quality of product is effectively ensured, meanwhile, can effectively reduce
The design difficulty of mould, reduces mould and manufactures cost and product injection cost；Mechanism and mould structure design are reasonable, structure
Compact, working stability is safe and reliable.
Brief description of the drawings
Fig. 1 drives slip core-drawing demoulding mechanism structure composition schematic diagram outside mechanical side for T-shaped piece for the present invention；
Fig. 2 drives slip core-drawing demoulding mechanism outside mechanical side to be installed and operating diagram on mould for T-shaped piece for the present invention.
Specific embodiment
Fig. 1-2 show related description figure of the present invention；Core-drawing demoulding mechanism is slided outside the T-shaped piece of mechanical side of driving, including
Pull bar screw 1, pull-rod spring 2, briquetting 3, sliding block spring 4, sliding block pull bar screw 5, slide body 6, as shown in Figure 1.
T-slot is designed with the slide body 6, for the slide-and-guide of slide body 6；Inclined-plane is designed with slide body 6, is used
In locking positioning.
The sliding block pull bar screw 5 that the slide body 6 is provided with plays sliding block sliding stroke control action, and sliding block spring 4 is installed
In in sliding block pull bar screw 5, be slide body 6 provide motion-promotion force.
The briquetting 3 is installed in mould template block slots, and briquetting 3 can be moved in block slots.
The pull bar screw 1 is installed on briquetting 3 through template screw, and the pull-rod spring 2 after compression is provided with thereon, is drawn
Bar spring 2 relies on mould template, is that briquetting 3 provides motion-promotion force by pull bar screw 1.
Designed for double inclined plane the lower end of the briquetting 3.
Further, illustrated for ease of operation principle of the invention, the mould mating parts that Fig. 2 need to be pointed out include upper clamping plate
7th, 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, top
Pin push pedal 15, die shoe plate 16；PL1 first switches on die joint for mould, and PL2 opens die joint for the second time for mould；Sliding block
Body 6 is installed on core mold insert 11 by T-slot shown in Fig. 2, and sliding block pull bar screw 5 passes through with holes spacing on core mold insert 11
Baffle plate is coupled with slide body 6；Impression bolster 9, die cavity mold insert 10 offer the groove position of the motion of voltage supply block 3；Pull bar screw 1 is passed through
The screw of template impression bolster 9 is installed on briquetting 3, and the pull-rod spring 2 after compression is provided with thereon, and pull-rod spring 2 relies on mould
Tool template impression bolster 9, is that briquetting 3 provides motion-promotion force by pull bar screw 1；It is designed with intermediate plate 8 and supplies pull bar screw
1st, the via that pull-rod spring 2 passes through.
During real work, as shown in Fig. 2 its motion operation principle is as follows：
1）The injection of product cavity side inner reverse fastener side core-pulling demoulding mould die cavity is completed, and mould is started to open at, on injection machine top
Under the pulling of bar, mould dynamic model part progressively separates with cover half part, now, in the presence of mould spacing controlling organization, mould
Tool is first switched on to be opened at PL1 die joints, and PL2 die joints are then remained closed and do not separated；In Fig. 2, upper clamping plate 7, centre
Plate 8 is fixed and stays motionless with injection machine cover half, pull bar screw 1, pull-rod spring 2, briquetting 3, sliding block spring 4, sliding block pull bar screw
5th, 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, top
Pin push pedal 15, die shoe plate 16 are then moved down；Pull bar screw 1 will lose the barrier force of upper clamping plate 7, so that, pull-rod spring 2
There is the bounce for withstanding the head of screw 1, press against screw 1 and be adjacent to upper clamping plate 7, be then to push down on impression bolster 9 in turn
From, and briquetting 3 is coupled with screw 1 to be screwed, thus, briquetting 3 will be hauled the pressure progressively lost to slide body 6 by screw 1
Tight effect；Once the thrust on the right side inclined-plane of slide body 6 progressively loses, sliding block spring 4 will promote slide body 6 to be done along T-slot
Side core-pulling motion to the right, until the core_pulling demoulding at the back-off position on product is completed, sliding block pull bar screw 5 is set by slide body 6
The baffle plate of meter is blocked, and its core pulling action to the right is limited, so as to reach the mesh of the product cover half side inside block side core-pulling demoulding
's；
2）The ejection of product
After the completion for the treatment of product cavity side inner reverse fastener side core-pulling stripping action, in the presence of mould spacing controlling organization, mould
First switch on and opened at PL2 die joints, so as in mould-ejecting plate thimble cover plate 14, thimble push plate 15 and die ejector pin
Under ejection, product is ejected from die cavity mold insert 10, complete the demoulding of whole product.
3）When resetting, with product ejection process conversely, in the presence of mould spacing controlling organization, mould is present
Closed at PL2 die joints, then closed at PL1 die joints again, screw 1 will press against by upper clamping plate 7 pull-rod spring 2 is entered
Row compression, meanwhile, screw 1 will promote briquetting 3 that slide body 6 is pushed back into reset, and mould closure waits next injection cycle to open
Begin.
Specific embodiment described herein is only the technology neck belonging to the present invention to the present invention spiritual explanation for example
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from spirit of the invention or surmount scope defined in appended claims.
