Description
Technical field
The utility model relates to a kind of mould structure, the mould structure that especially a kind of secondary ejects.
Background technology
No matter generally speaking, from mould, take out finished product, be to adopt the single or ejecting mechanism of multicomponent, and it ejects action all is once to accomplish.But because the shape of finished product is special, or the requirement during volume production, if after once ejecting, finished product or can't come off automatically the time, just needs to increase again and once ejects action still in die cavity.Like this eject action design, be called secondary and eject.
Secondary ejects to let and ejects smooth and easyization of flow process, for the bigger product of some ejection stroke demand, utilizes secondary to eject and can reduce the strength that thimble applies when ejecting, and causes the defective on the product when avoiding ejecting.
Secondary ejects and mainly is used in forced stripper mechanism, product is deep or avoid under the situation that cast gate pulls.
The service life of mould and the automaticity of forming process are to pass judgment on the good and bad principal element of mould always, because these directly have influence on formed in mould cost and efficient.The purpose of present technique research is to pass through the design of comparatively simple mould structure on the one hand, realizes that product drops automatically, thereby realizes automated production, on the other hand, requires this structure easy for installation, stability height, long service life.
Summary of the invention
The technical problem that the utility model will solve is to provide that a kind of injection moulding process is stable, product ejects balance, and is indeformable and can realize the mould structure that the secondary of automated production ejects.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: design the mould structure that a kind of secondary ejects, comprise front mould and back mould; Said front mould comprises panel and A plate, and said A plate is provided with hot mouth, and said back mould comprises B plate and ejector retainner plate; Said ejector retainner plate comprises first ejector retainner plate and second ejector retainner plate, and said first ejector retainner plate is provided with oblique thimble, and said second ejector retainner plate is provided with thimble; On the mould of said back secondary ejecting mechanism is installed, said secondary ejecting mechanism comprises guide post, mold insert, release lever and back-moving spring, and said mold insert slides along guide post; One end of said mold insert is provided with back-moving spring; The other end of mold insert withstands on the side of said release lever, release lever with contacted of mold insert on be provided with release portion, when said mold insert slides into said release portion; Said mold insert breaks away from guide post, and said mold insert stops the promotion to first ejector retainner plate.
As the improvement to the utility model, said release lever is arranged between said B plate and the base plate and with screw and fixes, and said guide post and said mold insert are arranged on the described ejector retainner plate.
As the improvement to the utility model, said secondary ejecting mechanism is that the line of symmetry symmetry is provided with the central vertical line of ejector retainner plate.
As the improvement to the utility model, the upper and lower both sides of said mold insert respectively are provided with a wearing plate.
As the improvement to the utility model, said mold insert and said release lever constitute the set a distance stopping means.
As the improvement to the utility model, said ejector retainner plate is provided with dead slot on the relevant position that said secondary ejecting mechanism is installed.
As the improvement to the utility model, said guide post has through hole on the relevant position that said mold insert and said slide block are installed.
As the improvement to the utility model, said hot mouth advances the hot mouth of plastic structure for point.
The utility model compared with prior art, structure is more reasonable, makes more simply, can effectively reduce cost, and improves the efficient of injection moulding greatly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the mould structure that the utility model secondary ejects comprises front mould and back mould, and said front mould comprises panel 11, flow distribution plate 12 and A plate 13; Said back mould comprises B plate 14 and ejector retainner plate, and said ejector retainner plate comprises that first ejector retainner plate 10 and second ejector retainner plate, 9, the first ejector retainner plates 10 are provided with oblique top 6; Second ejector retainner plate 9 is provided with thimble 8; Said second ejector retainner plate 9 is provided with guide post 2, and mold insert 3, wear-resistant block 4 and back-moving spring 5 are fixed with release lever 1 on the mould of said back; Said guide post 2, mold insert 3, wear-resistant block 4, back-moving spring 5 and release lever 1 common formation secondary ejecting mechanism; Said mold insert 3 slides along guide post 2; One end of said mold insert 3 is provided with back-moving spring 5; The other end of mold insert 3 withstands on the side of said release lever 1, release lever 1 with 3 contacted of mold inserts on be provided with release portion 7, when said mold insert 3 slides into said release portion 7; Said mold insert 3 breaks away from guide post 2, and said mold insert 3 stops the promotion to first ejector retainner plate 10.
The said secondary ejecting mechanism of the utility model has been symmetrical set two about ejector retainner plate central vertical line.Release lever 1 usefulness screw is fixed on the B plate, and guide post 2, mold insert 3, wear-resistant block 4 and back-moving spring 5 have been installed respectively on the ejector retainner plate.After mould is loaded onto injection machine, the mould matched moulds, sizing material melts through screw rod, flows into hot flow path from hot mouth, gets into die cavity through hot flow path again.After sizing material is full of die cavity, sizing material cooling a period of time, after cooling off fully, product carries out die sinking; Ejector retainner plate withstands second ejector retainner plate 9, thereby drive guide post 2 promotes 10 motions of first ejector retainner plate under the effect of mold insert 3 and slide block, and tiltedly thimble 6 makes product break away from back-off with thimble 8 motions; Move to the desired location of release lever 1 when mold insert 3; Release lever 1 promotes mold insert 3 and breaks away from second ejector retainner plate 9 and 10 stop motions of mold insert 3 promotion slide blocks disengaging guide posts 2, the first ejector retainner plates, is contained in the also stop motion together of oblique thimble 6 on first ejector retainner plate 10; Second ejector retainner plate 9 continues motion; Thimble 8 on second ejector retainner plate 9 is motion together also, ejects product, thereby has realized dropping automatically.
The mould structure that the utility model secondary ejects is reasonable in design, simple in structure, realizes that product drops automatically, thereby realizes automated production, and on the other hand, require this structure easy for installation, stability is high, long service life.
