Auxiliary ejection, to protect the integrality on plastic surface；The die sinking face of mold is single die sinking face PL；To guarantee that mold is opened face PL
After opening, the accuracy of mold dynamic model and cover half closure resetting, mold is protected in addition to the cooperation using guide post 34, guide sleeve 33
Card is outer, in addition goes out 4 tiger's jaw cooperation platforms in the guide post position Milling Process of moving template 8 and solid plate 3, to enhance fixed half and moving half
Accuracy when closure.
The end inner hole H1, the end inner hole H2 of the mold object plastic respectively use sliding block to carry out side core-pulling demoulding, Q2,
The region Q3 then respectively carries out side core-pulling demoulding using an oblique top；The region Q1, Q4 then respectively using modified slide block mechanism into
The demoulding of row side core-pulling；The mechanism structure of the side H1, H2 is identical, and the mechanism structure in the region Q2, Q3 is identical, the machine in the region Q1, Q4
Structure structure is also identical.
The H1 stomidium core-pulling mechanism thus use oil cylinder driving sliding block carry out side core-pulling more be suitable for, mechanism component part
Including left slider 3, left slider bottom plate 4, left slider gib block 5, left slider oil cylinder 6, left cylinder support 7；Left slider 3 drives simultaneously
Two intracanalicular type cores, when managing the type core combination at interior both ends, together using conical surface positioning method butt, the empty avoiding distance after butt
For 1mm in order to avoid dieback when the type core butt at both ends, and cause butt unstable, deforms, cause under the impact of high-pressure injection moulding stream
Plastic parts moulding failure, the gradient of frustum are 5 degree；For the cooling of enhanced core, type core inner is carried out cold using the well type of cooling
But.
In actual work, the course of work (application method) of mechanism is divided into following steps: mold die sinking is single point
Type, as shown in connection with fig. 3, when die sinking, latch segment 25 releases the locking to small slide block 26, and mold is opened at PL die joint, small cunning
The synchronous driving small slide block 26 of block guide post 24 completes the side core-pulling demoulding in region at two products 8；It is left after dynamic model retreats certain distance
Sliding block oil cylinder 6, the movement of right sliding block oil cylinder 21 respectively drive left slider 3, right sliding block 22 realizes the core_pulling demoulding of plastic inner hole；It is dynamic
Mould continues to retreat, and injection molding top rod driving liftout plate pushes two ejector sleeves 13 to eject upwards, synchronously, the driving molding mold insert of mandril 14
14-1 is ejected upwards, finally ejects plastic from type core, to realize the complete demoulding of plastic；
When reset, process is left slider oil cylinder 6, right sliding block oil cylinder again on the contrary, two ejector sleeves 13, mandril 14 first reset
21 movements reset, and last small slide block 26 resets, and mold closure waits next injection cycle.
