Description
Technical field
Fix mold insert injection mold in the present invention relates to a kind of mould, belong to moulding manufacturing technology field.
Background technology
The fast development of mold injection technology, in order to reduce processing procedure, cost-effective, in-mode inserts injection is more and more universal, meanwhile, can synchronize to realize the Shooting Technique IMD also fast development of exquisite product appearance, but, at present for the fixation problem of in-mode inserts, it is generally required to design a particular organization on product, increase mould structure cooperation realizes mold insert and fixes, and causes product design and mold mechanism to become complicated, some product, because structure problem, even needs to be molded to assemble later.And the thin film in IMD technique because unfixing, frequently result in thin film off normal, drop, the bad problem such as encapsulated produces, adding the means such as electrostatic even if sometimes using, also cannot be fully solved this problem.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, and existing injection mold easily carries out structure of modification, and design simplifies, be not likely to produce mold insert off normal, drop, the problem such as encapsulated, fix mold insert injection mold in the mould that mold insert injection yields is high；Further, the present invention provides a kind of spring-compressed rate adjustable, and movable part is adjustable to oppressing dynamics suffered by mold insert; convenient and reliable; directly on injection machine, dynamics suffered by mold insert can be adjusted according to production status, in saving upper and lower mould, dismounting mould and the mould of downtime, fix mold insert injection mold；Further, the present invention provides the installation direction of a kind of fixing insert structure both can be consistent with stripping direction, also can or other angles vertical with stripping direction, fix mold insert injection mold in the mould that motility is strong.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
Mold insert injection mold is fixed in a kind of mould, including the caster coordinated up and down and male template, it is provided with mother module core in described caster, it is provided with male die core in described male template, some die die cavities it are provided with in described male die core and mother module core, it is provided with fixing insert structure in described male die core below described die die cavity, described fixing insert structure includes spring, described spring is connected with the contact jaw of described die die cavity movable part, the described spring other end connects set screw, described movable part is T-shaped, described spring is arranged in the first cavity of cylindricality, described movable part includes limited step, described limited step is positioned at described first cavity, the opposite end of described first cavity and described die die cavity is provided with the through hole of the rod end for passing described movable part.
Described die die cavity includes the 3rd cavity；Or the 4th cavity that the 5th cavity plus is connected with described 5th cavity.
Described 4th cavity can put into the second mold insert, and described second mold insert connects with described 5th cavity.
The top of described movable part passes the top of described male die core and described 3rd cavity top is provided with gap one when not being molded, described set screw outer end is movably set in described male die core surface, is provided with gap two between described male template lower surface and ejector retainner plate upper surface.
First mold insert is positioned at described 3rd cavity, and its thickness is more than described gap one.
Described die die cavity is all connected with plastic cement runner.
Some thimbles it are provided with in described ejector retainner plate；Described thimble includes the first thimble for ejecting runner, also includes the second thimble of product after ejecting injection.
Described set screw is arranged in the second cavity of cylindricality, and described second cavity sidewalls has screw thread, described second cavity and the first cavity to be connected, and described set screw is rotatable and passes described male die core.
The rod end of described movable part is smooth circular arc.
The inwall of described second cavity is provided with female thread, and described female thread matches with the external screw thread of described set screw.
Movable part can be set to circle, the arbitrary shape such as square, to meet product requirement according to product and mould structure.
Compared with prior art, the invention has the beneficial effects as follows: a movable part is set in mould, after matched moulds, mold insert is fixed in mould by the elasticity utilizing spring, when the plastic cement of molten condition injects die die cavity from plastic cement runner, movable part is under the plastic cement of high-voltage high-speed extrudes, movable part retreats, leave plastic cement space, owing to the present invention utilizes movable part to fix mold insert, the setting that mold insert is connected with spring, when not being molded, movable part can the most firmly prop up mold insert, avoid mold insert dislocation or be subjected to displacement, it is not likely to produce both cast film off normal, drop, the problem such as encapsulated, the yields of mold insert both cast film product is high, production efficiency is high；In injection moulding process, movable part is under the plastic cement of high-voltage high-speed extrudes, and movable part retreats, and leaves plastic cement space, makes the mold insert bearing also can be with the presence of plastic cement；Set screw and the setting in gap two, can regulate spring-compressed rate further by adjusting set screw, makes movable part adjustable to oppressing dynamics suffered by mold insert, and mold insert bearing plastic cement thickness is adjustable, convenient and reliable；The setting of limited step, makes movable part and die die cavity have certain distance (i.e. gap one), the die mold cavity surface in order to avoid movable part is damaged；Meanwhile, above ejector retainner plate and below male template between be provided with gap two, convenient directly use instrument to adjust set screw on injection molding machine to control spring-compressed ratio；The mold insert need to being combined with plastic cement is placed in die die cavity, notices that mold insert thickness need to be more than the thickness in gap one, in order to movable part fixes mold insert under the force of a spring, according to die trial and production status, adjusts spring-compressed ratio and controls the movable part pressure to mold insert；Movable part retreats under the high pressure that plastic cement flows, and in injection moulding process, movable part position can be filled into plastic cement equally, does not thus interfere with product structure, and by controlling spring-compressed ratio, can control movable part set back distance.Present configuration is simple, and existing injection mold easily carries out structure of modification, and design simplifies, easy for installation, improves and produces yields and efficiency.
As required, fixing insert structure installation direction both can be consistent with stripping direction, also can or other angles vertical with stripping direction.
