Description
Technical field
The utility model relates to a kind of automobile bumper injection mould tool, and especially a kind of matched moulds protection mechanism of bumper inner part line injection mold, belongs to injection molding technology field.
Background technology
Adopt the bumper product of inner part line Shooting Technique moulding, with the good advantage of its exterior quality, be widely used on modern high-grade car, referring to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, because bumper product 1 inner part line is set on hiding flange 1-1, at injection molding mould fixed die, partly there is back-off position Ω, therefore need to adopt the special-purpose smooth depanning of slanted ejecting mechanism guarantee injecting products.
Referring to accompanying drawing 3, accompanying drawing 4, because slanted kicking block 2 and the cover half 4 of inner part line bumper mold has small stack amount Σ in the horizontal direction, if press the matched moulds order matched moulds of ordinary injection die, will cause cover half 4 and slanted kicking block 2 to collide.For avoiding cover half 4 in injection mould closing process to interfere with slanted kicking block 2, in bumper, divide a mould generally by hydraulic control mode or below ejector retainner plate, to increase nitrogen spring and avoid ejector retainner plate antecedence reposition, thereby realize cover half, promote ejector retainner plate matched moulds together.But above-mentioned solution is higher to the performance requirement of injection machine, be difficult to mate with the injection machine of common model, and extended the mould matched moulds time, restricting the raising of injection mo(u)lding production efficiency.
Utility model content
The purpose of this utility model is the drawback for prior art; provide the frame for movement of a kind of energy by injection mold to control mould opening and closing mould sequence of movement, can on common injection machine, complete minute mould protection mechanism in the bumper of inner part line product injection mo(u)lding.
Problem described in the utility model realizes with following technical proposals:
Minute mould protection mechanism in a kind of bumper; it comprises latch, pressing plate, limited block and release link; the cover half of described latch and injection mold and dynamic model are equipped; at latch outside suit limited block and pressing plate; described pressing plate is positioned at above limited block; both are all inlaid in dynamic model internal cavities, and described release link lower end is fixed on ejector retainner plate, and its top penetrates in dynamic model internal cavities.
Minute mould protection mechanism in above-mentioned bumper, described latch top is fixed on cover half by latch briquetting, and its shaft penetrates in dynamic model cavity, in latch bottom, is provided with the wedge-like engagement face mating with limited block.
Minute mould protection mechanism in above-mentioned bumper, described limited block is provided with Compress Spring installation cavity, in Compress Spring installation cavity, assembles Compress Spring, and conflict with limited block and dynamic model cavity inner wall respectively in described Compress Spring two ends.
Minute mould protection mechanism in above-mentioned bumper, described limited block is also provided with wedge-shaped slot on the inwall of latch pilot hole, and described wedge-shaped slot mates with latch wedge-like engagement face.
Minute mould protection mechanism in above-mentioned bumper, described release link is provided with avoiding hollow groove, and described avoiding hollow groove mates with limited block.
In above-mentioned bumper, minute mould protection mechanism, is provided with dynamic model mating surface place the cushion block mating with release link at cover half, and described cushion block is fixed on cover half.
The utility model is controlled the position of limited block in mould matched moulds different phase by latch, by limited block, coordinated with release link to prevent because ejector retainner plate cover half and the slanted kicking block causing that first reset collides, thereby guaranteed the smooth matched moulds process of minute mould in bumper.When mould die sinking, first dynamic model band dynamic pressure plate, limited block move a certain distance backward, now latch, latch briquetting, ejector retainner plate, straight jacking block, product keep static, slanted kicking block moves deformation of products space is provided to mold center, and oblique push block pulls flange move and depart from cover half back-off to mold center under guide plate guiding; Then product and dynamic model integral body move down, make product separated with cover half die cavity, slanted kicking block continues to move to mold center simultaneously, product takes off flange back-off, oblique push block under guide plate guide effect outside mould side shifting, product recovers original shape, now the limited block of minute mould protection mechanism is moved to the left under the effect of Compress Spring in this bumper, the wedge-like engagement face laminating of limited block wedge-shaped slot and latch bottom, limited block enters in the avoiding hollow groove of release link; Finally by ejector retainner plate, drive straight push rod, straight jacking block that product is ejected, release link moves up and contacts with cushion block on cover half under ejector retainner plate drives simultaneously, so far completes die sinking action.When mould matched moulds, first ejector retainner plate drives straight push rod, angle ejector rod and release link to move down, and after limited block contacts with the avoiding hollow groove top edge of release link, ejector retainner plate stops action, then dynamic model moves up, latch is stirred limited block and is moved right, and limited block exits the avoiding hollow groove of release link, and cover half is being pressed straight jacking block matched moulds together, because cover half moves downwards, and slanted kicking block moves along direction horizontally outward simultaneously, therefore avoided interference between the two, make mould complete smoothly mould assembling action.In a word, the utility model can be controlled mould opening and closing mould sequence of movement by the frame for movement of injection mold, can on common injection machine, complete the injection mo(u)lding processing of inner part line product, not only guarantee the exterior quality of bumper product, and reduced production cost.
