Referring to fig. 1 to 3, the injection mold lifter mechanism according to the embodiment of the present invention includes a lifter block 11, a lifter rod 12 and a locking device.
Specifically, the inclined ejecting block 11 is provided with a fixing hole, and the cross section profile of the fixing hole comprises at least two different curves; one end of the ejector rod 12 is provided with a fixing part which is matched with the fixing hole; and a locking device for locking the lifter block 11 and the lifter bar 12. The fixing portion is matched with the fixing hole, and the cross-sectional profile of the fixing hole comprises at least two different curves. Because two different curves are not on the same arc, the ejector rod 12 can be limited to rotate around the axis of the ejector rod 12, and therefore the ejector rod 12 and the inclined ejector block 11 are prevented from rotating relatively.
It will be understood that the above "two different curves" means that the curves have different or the same radius of curvature but the two curves do not coincide in their centre.
The cross section outline of the fixing hole on the inclined ejecting block 11 is set to comprise at least two different curves, and the fixing part of the ejector rod 12 is matched with the fixing hole, so that the inclined ejecting block 11 is prevented from rotating around the fixing part of the ejector rod 12; the locking device locks the inclined ejection block 11 and the ejector rod 12, and looseness between the inclined ejection block 11 and the ejector rod 12 is avoided. Set up in injection mold the utility model discloses the oblique ejecting mechanism of injection mold can avoid oblique ejecting block 11 and ejector pin 12 to produce relative rotation or not hard up, and then avoids the mechanism of pushing up to one side to pull by force or ejecting and damage the product.
It should be noted that the "curve" includes straight lines, circular arcs and multi-segment curves.
In some embodiments, the cross-sectional profile includes a straight segment and a circular arc segment, a central angle of the circular arc segment is greater than 180 °, and two ends of the straight segment are connected with two ends of the circular arc segment respectively. The central angle of the circular arc is larger than 180 degrees, the fixing part can be guaranteed to have enough structural strength, and the situation that the ejector rod 12 is bent or even broken in the using process can be effectively avoided. Furthermore, the cross-sectional profile of the fixing portion has a circular arc segment, in other words, the fixing portion has a circular arc surface. The arc surface can be processed by a conventional processing technology, so that the manufacturing and processing difficulty of the ejector rod 12 is reduced. In addition, the fixing part can be in close contact with the fixing hole, and the assembling precision is guaranteed.
In one embodiment, the top bar 12 includes a first bar 121 and a second bar 122, the outer profile of the first bar 121 matches the profile of the fixing hole, the cross-sectional area of the second bar 122 is larger than that of the first bar, and the end surface of the second bar 122 abuts against the slanted ejecting block 11. The terminal surface and the oblique kicking block 11 of second branch 122 are direct to offset, can effectively avoid locking device to become invalid in follow-up use on the effort direct action that oblique kicking block 11 bore ejector pin 12, in order to improve the utility model discloses the working life of embodiment.

Further, the end surface is closely attached to the bottom surface of the lifter block 11, as shown in fig. 2. Under the condition of ensuring the matching installation of the fixing part of the mandril 12 and the fixing hole of the inclined jacking block 11, the end surface can be in close contact with the side surface of the inclined jacking block 11, so that the acting force born in the inclined jacking block 11 can be uniformly transmitted to the mandril 12. The arrangement can effectively avoid the situation that the locking device is only used for bearing the external acting force applied to the reciprocating motion of the inclined ejecting block 11, and further ensure the close fit between the inclined ejecting block 11 and the ejector rod 12.
In one embodiment, the locking device is a pin 13, the lifter 11 and the mandril 12 are both provided with locking holes, the locking holes penetrate through the lifter 11 and the mandril 12, and the pin 13 is matched with the locking holes. The inclined ejecting block 11 and the ejector rod 12 are tightly fixed by a pin 13 penetrating through the ejector rod 12 and a locking hole of the inclined ejecting block 11.
In other embodiments, the locking device is a locking screw, and locking holes are formed in the lifter block 11 and the lifter 12 and matched with the locking screw.
