Embodiment

Lock core injection mold, including fixed half and moving half, cover half have the panel 2 from top to bottom set gradually, runner plate 3 and on Template 4, cover half is interior to set sprue bush 1 and pull bar guide pillar 9, and two upper cores 5, sprue bush 1 and two upper moulds are set in cope plate 4 The material road 23 of taper is set between benevolence 5, the smaller diameter end of material road 23 is located at top, two fixing grooves 26 is opened up on cope plate 4, Gu It is outside positioned at the corresponding bottom of upper cores 5, the vertical slide block guide rail 6 of the both sides of panel 3 setting, the lower end of slide block guide rail 6 to determine groove 26 Tilt, sprue puller 7 and locking device are set between panel 2 and runner plate 3, hexagonal socket head cap screw is set between runner plate 3 and cope plate 4 8, dynamic model has the lower template 17 from top to bottom set gradually, square iron 8 and bottom plate 21, and ejector retainner plate 19 and thimble bottom are set in square iron 8 Plate 20, lower die 14 is set, and lower die 14 is by the first sliding block 10, the second sliding block 11, the 3rd sliding block 12 and the 4th in lower template 18 Sliding block 13 is formed, and the first sliding block 10 and the second sliding block 11 cooperate, and the 3rd sliding block 12 and Four-slider 13 cooperate, and first Sliding block tie rod 15 is respectively provided between sliding block 10 and the bottom of the 3rd sliding block 12, between the second sliding block 11 and the bottom of Four-slider 13, the One sliding block 10 and the sidepiece of Four-slider 13 set slide block insert 22 respectively, and slide block guide rail 6 is slidably mounted in slide block insert 22, under The both sides of die 14 set slider layering 16, the first sliding block 10, the second sliding block 11,13 equal energy of the 3rd sliding block 12 and Four-slider respectively It is enough to be slided along the slider layering 16 of both sides, several thimbles 24 are set on ejector retainner plate 19, set on the second sliding block 11 and the 3rd sliding block 12 Several push rods 25 are put, thimble 24 overlaps with the corresponding axis of push rod 25, the first sliding block 10 and the second sliding block 11, the and of the 3rd sliding block 12 Four-slider 13 is respectively positioned in corresponding fixing groove 26.This structure can be slided in the first sliding block 10 and the second sliding block the 11, the 3rd Sufficient amount of injection molding cavity is opened up on block 12 and Four-slider 13, to be once molded greater number of product, this structure is set Count compact, linked two-by-two by four sliding blocks, sliding block is by slide block guide rail 6 by way of slide block insert 22 drives so that lower mould Benevolence 14 is compact-sized and conveniently stripped, can be produced thereby using small injecting machine, and injection cost is relatively low.The minor diameter of material road 23 End is located at top, and during the demoulding, the product being molded by automatically disengages with waste material at the smaller diameter end of material road 23, the work manually separated Work amount is small.During mould matched moulds, slide block guide rail 6 drives slide block insert 22 to move, and the first sliding block 10 and Four-slider 13 is driven the Two sliding blocks 11 and the 3rd sliding block 12 move so that the first sliding block 10 and the second sliding block 11, the 3rd sliding block 12 and Four-slider 13 close Close.After closure, cope plate 4 and the matched moulds of lower template 18 start to be molded in place.When mould molds, in locking device and sprue puller 7 Under effect, mould separates between runner plate 3 and cope plate 4 first, the minor diameter of the product being molded by and waste material in material road 23 Automatically disengaged at end.When mould continues to shrink back, hexagonal socket head cap screw 8 encounters runner plate 3, and panel 2 and runner plate 3 separate, runner plate 3 Waste material is scraped from sprue puller 7.Mould continues to shrink back, and slide block guide rail 6 drives slide block insert 22 to move so that four sliding block phases It is mutually mobile simultaneously to separate, push rod 25 be moved to corresponding to thimble 24 position, and the ejecting product and useless in the presence of thimble 24 Material.During demoulding, Yun Shui water routes cooling mould.

Described locking device can have various structures, preferably there is the fixed cylinder 27 and locking post 31 of upper end open, Gu Safety barrel 27 is fixed on runner plate 3, and locking post 31 is fixed on panel 2, and one end of back-moving spring 28 is set in fixed cylinder 27, multiple The other end of position spring 28 sets circular fixed plate 29, and fixed plate 29 is located in fixed cylinder 27, and the top of fixed plate 29 is along border The latch 30 that several upper ends are outward-dipping is set, and the diameter of locking post 31 is identical with the diameter of fixed plate 29.This structure energy The enough elastic force by changing back-moving spring or reconciling back-moving spring, adjust fixed plate 29 and the height and position of latch 30 Section, so as to change the distance between latch 30 and locking post 31, because the distance that locking post 31 pushes is constant, institute With, the position of latch 30 is more upward, locking post 31 push it is smaller with the frictional force of latch 30 afterwards, so as to convenient regulation counter plate 2 coupling mechanism force, it is conveniently stripped.Described locking device can also be shutter or nylon rises plug, it is this simple in construction, but its nothing The coupling mechanism force of method counter plate 2 is adjusted.

The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This practicality is new The technology contents of the not detailed description of type are known technology.
