Description

Flexible deformation combined injection molding die for serialized products
Technical field
The present invention relates to a kind of injection mold, specifically a kind of flexible deformation combined injection molding die for serialized products, belongs to the technical field of mold in mechanical engineering.
Background technology
Injection mold is the important mechanized equipment of producing plastic products.The quality of product quality, the height of precision is closely related with it.Along with 3C(Computer, Communication, Consumer Electronic) the developing rapidly of product, the speed of model change is also accelerated thereupon.
The injection mold in prior art field mostly manufactures and designs for the product of a certain fixedly specification, and its core rod and mould bases are all only applicable to the production of this product, and different model product needed designs even mould bases of different core rods, and versatility is not strong.Product for producing in serial form, its specification, shape facility change little, if a kind of product has a lot of models, and each model is all removed to manufacture and design a kind of mould, and must need to design and manufacture a lot of molds, so not only increased product cost, and need often to change different moulds while producing plastic part, reduce production efficiency, caused the production cycle of product long simultaneously, incured loss through delay the time of product occuping market.
Therefore a kind of development of injection mold of simple in structure, production tandem product that production efficiency is high just seems very necessary.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of plastic deformation sectional die of satisfied production tandem product is provided, it can realize the producing in serial form of product, produce a kind of series of products with a lot of models, can, with same secondary mould bases, adopt and change the plastic part that different interchangeable core rods is produced the different model of same series.
The present invention is comprised of part of the upper die and part of the lower die, and described part of the upper die comprises upper bolster, intermediate plate, caster, interchangeable master mold, able to quickly change master mold mold insert, the limit of baroclining, centring ring, sprue bush etc.; Described part of the lower die comprises die shoe, feet, male model plate, interchangeable male model, able to quickly change male model mold insert, the limit etc. of baroclining.
The present invention is different according to serial model, the one or more or all replacings in replaceable different interchangeable master mold, able to quickly change master mold mold insert, interchangeable male model, able to quickly change male model mold insert.
Interchangeable male model of the present invention, interchangeable master mold, able to quickly change master mold mold insert, able to quickly change male model mold insert and universal die set adopt and removably connect, and interchangeable male model mold insert and able to quickly change master mold mold insert are arranged on respectively in the groove in interchangeable male model and interchangeable master mold; The appearance and size of able to quickly change master mold mold insert and able to quickly change male model mold insert respectively with the interior shape consistent size of interchangeable master mold and interchangeable male model groove; The appearance and size of interchangeable master mold and interchangeable male model respectively with the interior shape consistent size of caster and male model plate mounting groove.Able to quickly change master mold mold insert and able to quickly change male model mold insert adopt interference fits with the groove of interchangeable master mold and interchangeable male model respectively; Described interchangeable master mold and interchangeable male model adopt matched in clearance with the inside groove of caster and male model plate respectively.
Interchangeable male model of the present invention and interchangeable master mold are arranged on respectively in male model plate and caster, with two perpendicular edge positioning and lockings of two interchangeable male models in the edge that baroclines, interchangeable master mold, then with eight block pressur plates, they are fastened on respectively on male model plate and caster.
The limit of baroclining of the present invention is a kind of one to wear the wedge of gradient, and interchangeable male model and interchangeable master mold are played to locking effect.
The present invention, for the ease of dismounting, offers lifting screwed hole in the middle of the described limit upper surface that baroclines and is used for pulling down the limit of baroclining; On described interchangeable master mold and the upper surface diagonal angle of interchangeable male model, offer two lifting screwed holes and be used for pulling down interchangeable master mold and interchangeable male model.
The present invention adopts same secondary injection mould universal die set, comprises centring ring, sprue bush, upper bolster, intermediate plate, caster, die shoe, feet, male model plate, outer guiding post, outer bush, interior guide pin bushing, inner guiding post.
When male model plate of the present invention and caster work, by inner guiding post and interior guide pin bushing, lead, during mould bases work, by outer guiding post and outer bush, lead.
The invention has the beneficial effects as follows: 1) for the consistent series of products of Outside Dimensions, only need to change core rod (male model or master mold), and without changing mould bases, save the quantity of mould bases, thereby reduced the production cost of product; 2), for product a series of, different model, if just local shape feature is different, only needs to change able to quickly change mold insert, thereby obtain tandem product.3) can carry out the replacing of various combination form to interchangeable core rod and able to quickly change mold insert, realize plastic deformation, thereby obtain the different different model product of geomery.(4) during for the different model product of production seriation; need not pull down universal die set; directly can on the mould bases that is arranged on injector template, change core rod (male model or master mold); saved like this time of die change and debugging; improve the production efficiency of mould; shortened the development time of product, thereby increased economic efficiency.
