During real work, as shown in figure 8, its motion operation principle is as follows：
By four partings during mold work, as shown in Figure 8；The I times parting PL1 partings at runner plate 4 and impression bolster 7
Face parting；Ii time parting is panel 3 and PL2 die joint punishment types at runner plate 4；I parting of ii be impression bolster 7 with
PL3 die joints punishment type at core fixing plate 10, iv time parting is first gear plate 11 and PL4 partings at core fixing plate 10
Face parting.
1) after first time parting mould is opened, Injection Motor Template driven mold dynamic model part is retreated, during the I times parting,
That is PL1 punishment type, with common three template die, the pushing open under effect of spring 49 is released in impression bolster, will runner plate 4 with
The interface of impression bolster 7 separate, runner waste material is fixed at it in the presence of sprue puller 27 of panel 3, at spot pouring mouth with
Product is separated, and is stayed in the side of runner plate 4；And additional runner plate 5, preceding mould ejector retainner plate 6 then follow the side of impression bolster 7, after
It is continuous to follow retrogressing；
2) second of parting will carry out II parting, i.e., in the presence of runner plate pull bar 48 between runner plate 4 and panel 3
PL2 punishment types, runner waste material is under the release effect of runner plate 4, charging ram spring 28, charging ram 29, by waste material from runner plate 4
On scrape, Automatic-falling；
3) I parting of third time parting ii is being opened at impression bolster 7 and core fixing plate 10 at PL3, i.e. PL3 punishment
Type, there is an important action during opening, i.e. preceding mould ejection at the position of place's die cavity thimble shown in product Fig. 1；Impression bolster 7, core are solid
When fixed board 10 is opened, by means of the effect of nylon buckles 37 and front thimble flat spring 30, preceding mould ejector retainner plate 6 will be front thimble 34 in the past
Mould is released to dynamic model side, is reliably stayed in so as to will renovate on dynamic mould core, is prevented product from renovating pulling for position；Ii I
After secondary parting, stationary mould for mould part is kept completely separate with dynamic model part；
4) the 4th parting dynamic model part is continued to retreat, strutted in core fixing plate under the pulling function of Injection Motor Template
Strutting for spring 52 is acted under the lower and pulling of core fixing plate pull bar 50, and core fixing plate 10 will stop motionless, it is impossible to continue
Dynamic model is followed to retreat, mould will produce iv time parting, i.e. PL4 die joints between core fixing plate 10 and first gear plate 11
Parting；During parting, oil cylinder with gear racks 25 starts action, and band carry-over bar 47 and thread core gear 44, thread core 40 are moved, real
Existing one side Leave out thread, core fixing plate 10 is under the withstanding that core fixing plate struts spring 52, and core fixing plate 10 promotes ejection
The one side of mold insert 41 ejects product from central core push rod 38, pipe core 39；It ejects distance by core fixing plate pull bar
51 spacings are controlled, and treat that screw thread is deviate from, valve 53 leads to pressure-air, and air will be from central core push rod 38, pipe core 39, screw thread
Product is blown out ejection by the space between core 40 from core, so as to complete the complete demoulding of product；
5) when resetting, thread core 40 first resets, and mould presses PL2-PL3-PL1-PL4 closing in sequence, and each part is multiple successively
Position, last 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 be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
