Described cavity side type pin demoulding B assembly comprises band T-slot wedge block 15, guide layering 16, type pin compact heap 17, type pin 18, type pin slide body 19; Band T-slot wedge block 15 is installed in mold panel by screw, and during die sinking, band T-slot wedge block 15 is with removing from mould pin 18 to loose core by the T-slot pulling type pin slide body 19 on it; Guide layering 16 plays to the guide effect of type pin slide body 19, and type pin compact heap 17 plays the effect of mount type pin 18, as shown in Figure 10.
Described end side surface demoulding C assembly comprise the inserted wedge block of T-slot 20, gib block 21, right side core slide body 22, T-shaped piece 23; The inserted wedge block 20 of T-slot is installed on stationary mould for mould plate by screw, be installed on the inserted wedge block 20 of T-slot by screw for T-shaped piece 23, during die sinking, the inserted wedge block of T-slot 20 drives right side core slide body 22 to complete action of loosing core by T-shaped piece 23; Gib block 21 plays as right side core slide body 22 slide-and-guide effect, as shown in figure 11.
Described molding structure part comprises solid plate 24, moving platen 25, core mold insert 26, die cavity mold insert 27.
During real work, as shown in Fig. 8, Figure 12, its motion operation principle is as follows:
1) after die sinking, mould divides to be opened for 2 times, and when first time opens, the first action of cavity side type pin demoulding B assembly, completes and loose core; Then A assembly slipper block loose core, C assembly slipper block loose core.
2) A assembly slipper block loose core operating principle is:
After die sinking, Injection Motor Template pulls mould dynamic model part to retreat, mould when die joint place goes out to open,
Angle Pin 3 stirs slide body 4, side slider head 1 skids off by F direction in Fig. 8 (a), now, because the oblique top head of angle ejector rod 12 has caught on mold cavity mold insert, it synchronously skids off along F direction so can not be followed, thus, angle ejector rod 12 has also held oblique top plate 8 by oblique top sliding pin 14, thus the situation that ejects of oblique top is that slide body 4 drives side slider head 1 to move, angle ejector rod 12 is then in passive drive motion state, when side slider head 1 skids off along F direction, angle ejector rod 12, the horizontal direction of oblique top plate 8 in Fig. 8 (a) does not move, vertical direction moves down, thus complete the synchronous demoulding of side slider head 1 and angle ejector rod 12 head, concrete corresponding motor point motion state is: when slide body 4, side slider head 1 skid off by F direction, G1 point on slide body 4 is progressively separated with the G2 point on oblique top plate 8, G3 point on side slider head 1 on G4 point and oblique top plate 8 is progressively close, angle ejector rod 12, oblique top plate 8 move by K direction, bottom angle ejector rod 12, relative oblique top plate 8 also has the relative movement in M direction, as shown in Fig. 8 (b), Fig. 9, thus ensure first to loose core in the back-off position of angle ejector rod 12 head, then angle ejector rod 12, side thimble 11, oblique top plate 8 are followed slide body 4 and are extracted out to short distance by F together, thus reach the effect of overall side core_pulling demoulding, during reset, Angle Pin 3 is stirred slide body 4 and is resetted, thus drive side slider head 1, oblique top plate 8, release link 9, side thimble 11, angle ejector rod 12 etc. to reset together, the spacing of oblique top plate 8 is ensured by the spacing release link 9 of release link wear-resistant block 10, last by wedge block 5 pressed slider body 4 to guarantee the complete reset of side slider head 1, mould closes, and waits for the beginning of next injection cycle, and die casting and structure installment are as shown in figure 12.
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.
