Fig. 2 is answered mould structure schematic diagram by a kind of cushion block spacing-type twice ejecting mechanism of the present invention and mould thereof;
Fig. 3 is a kind of cushion block spacing-type twice ejecting mechanism of the present invention and mould application ejecting mechanism operation principle schematic diagram thereof.
Detailed description of the invention
Fig. 1-3 is depicted as related description figure of the present invention; A kind of cushion block spacing-type twice ejecting mechanism and mould thereof, comprise the second thimble panel 1, second thimble push plate 2, cushion block 3, first thimble push plate 4, snap close 5, secondary angle ejector rod 6, secondary sprue puller 7, the straight push rod 8 of secondary, secondary thimble 9, tip-lever support 10, lengthen push rod 11.
Described one-level ejecting mechanism assembly composition comprises the second thimble push plate 4, the straight push rod 8 of one-level, tip-lever support 10; Tip-lever support 10 is installed on the first thimble push plate 4 by screw, and after installing, its bottom surface is than the low 5mm of the first thimble push plate 4, plays rubbish between control first thimble push plate 4 and lower mould seat board and retains gap and act on; Tip-lever support 10 offers T-slot, is convenient to the straight push rod 8 of secondary is installed; First thimble push plate 4 both sides offer side and partly take on boss, and boss width is 10mm; Thickness is the half of the first thimble push plate 4 thickness; Side on first thimble push plate 4 width is 2mm apart from the distance of cushion block 3.
Described secondary ejecting mechanism assembly composition comprises the second thimble panel 1, second thimble push plate 2, secondary angle ejector rod 6, secondary sprue puller 7, secondary thimble 9; Second thimble panel 1, second thimble push plate 2 is compoboard by screw fastening connection; Secondary angle ejector rod 6, secondary sprue puller 7, secondary thimble 9 are installed on the second thimble panel 1, compress installation by the second thimble push plate 2.
Described grading control assembly comprises cushion block 3, snap close 5; Be provided with the opening notch of L-type inside cushion block 3, eject distance for what control the first thimble push plate 4; Interlock connection before snap close 5 departs from for the second thimble push plate 2, first thimble push plate 4.
Described lengthening push rod 11 upper end is by screw fastening and the second thimble push plate 2, and middle through mould ejection hole, lower end and injection machine push rod connect, and upwards eject for promoting the second thimble push plate 2.
During real work, as shown in Figure 3, its motion operation principle is as follows:
1) after die sinking, Injection Motor Template pulls mould dynamic model part to retreat, mould goes out to open at die joint, when injection machine push rod withstand the second thimble push plate 2 eject time, second thimble push plate 2 drives the first thimble push plate 4 upwards to eject together by snap close 5, thus product and runner waste material synchronously eject by the straight push rod 8 of secondary angle ejector rod 6, secondary sprue puller 7, secondary, secondary thimble 9 together together; After ejecting, first thimble push plate 4 moves upward after H distance, on first thimble push plate 4, a point runs into the obstruction of b point on cushion block 3, now, snap close 5 is forced by external force and opens, first thimble push plate 4 can not continue to move ahead, but injection machine push rod can continue to head on lengthening push rod 11 to be continued up, second thimble push plate 2 continuation promotion secondary angle ejector rod 6, secondary sprue puller 7, secondary thimble 9 eject, until c point runs into the d point on mould moving platen on the second thimble panel 1, can not upward position be continued, thus reach the object by product and runner waste material Double-ejection;
2) when resetting, injection machine push rod, haul to lengthen push rod 11 thus haul the second thimble push plate 2 and push back reset, in reseting procedure, snap close 5 is locked by foreign compulsion, and the second thimble panel 1, second thimble push plate 2, first thimble push plate 4 is again locked and is integrated, till tip-lever support 10 is spacing by lower mould seat board, mould closes, and waits for the beginning of next injection cycle.
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.
