Lean on.
Brief description of the drawings
Fig. 1 directly pushes up ejecting mechanism and its injection mold application ejecting mechanism and its mould structure by a kind of spring of the present invention
Schematic diagram.
Embodiment
Fig. 1 show related description figure of the present invention；A kind of spring directly pushes up ejecting mechanism and its injection mold, including straight jacking block
1st, directly top spring 2, straight top pull bar 3, core mold insert 4, thimble panel 5, thimble push plate 6, lower die seat board 7, cushion block 8, guide post 9, dynamic
Template 10, solid plate 11, cavity mold insert 12.
A kind of spring directly pushes up ejecting mechanism and its injection mold, and the straight top component includes straight jacking block 1, directly pushes up spring 2, is straight
Top pull bar 3；Straight 1 upper end of jacking block is forming surface, while with the gradient bevel edge for being 2 °, its excess-three side is straight body face on periphery；
There is straight top pull bar 3 in straight 1 lower end of jacking block by spiral marking connection, and straight 3 bottom of top pull bar is provided with screw head, and screw head is hidden in thimble and pushes away
Corresponding to plate 6 in location hole, its lower end is 23mm apart from the distance H of lower die seat board in mould static state installment state；Straight top bullet
Spring 2 is installed in the correspondence position circle hole groove that moving platen 10 is opened up, and is placed on straight top pull bar 3, and straight jacking block 1 is close in the upper end
Lower face, the straight spring 2 that pushes up are in compressive state all the time at work；Straight top pull bar 3 passes through thimble panel 5 when being installed on mould
Hole set by upper correspondence position；Straight 3 main function of top pull bar is to ensure that the reliable reset of straight jacking block 1.
Mould structure composition includes core mold insert 4, thimble panel 5, thimble push plate 6, lower die seat board 7, cushion block 8, leads
Column 9, moving platen 10, solid plate 11, cavity mold insert 12.
In actual work, as shown in Figure 1, its movement operation principle is as follows：
1) Injection Motor Template pulls mould dynamic model part to retreat when molding, and mould goes out to open in die joint, when injection molding machine mandril
It is straight to push up spring 2 as thimble push plate 6 and thimble panel 5 loosen straight 3 tightening force of top pull bar when withstanding the ejection of thimble push plate 6
Compression stress be released, the straight spring 2 that pushes up releases straight jacking block 1 from core mold insert 4, so that auxiliary mould ejecting mechanism will produce
Product eject；
2) when resetting, thimble push plate 6 and thimble panel 5 are pushed back reset by mould ejection resetting-mechanism, so that thimble panel 5 passes through
Straight jacking block 1 is retracted reset by straight top pull bar 3, and screw head lower end is in mould static state installment state apart from the distance H of lower die seat board
There are enough adjustment spaces during for 23mm to reset, mould closure, waits the beginning of next injection cycle.
Specific embodiment described herein is only the technology neck belonging to the present invention to spirit explanation for example of the invention
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, but without departing from spirit of the invention or beyond the scope of the appended claims.
