Description
Technical field
The present invention relates to Mould design and manufacturing, is a kind of modular assembling die that is applicable to large-scale injection molding specifically.
Background technology
Injection molding technology obtains using very widely in the finished product manufacturing of all trades and professions, and its basic principle is to utilize the tube that shoots material of annotating the shape machine that thermoplastic is heated to molten condition, again vasopressing injection in the injection mold cavity through being condensed into goods.The basic characteristics of injection molded are to utilize injection tube that plastics are heated to the molten condition pressurization to inject die cavity formation finished product, and die cavity is made up of dynamic model and cover half, and the inside surface configuration of die cavity is consistent with the profile of finished parts.Dynamic model and cover half are to make through Precision Machining with the monoblock blank.Many with material in the ordinary course of things, processing charges is than higher, when the surface of finished parts is that complicated shape, wall thickness are thin, during larger-size workpiece or finished parts when being in variable condition according to market demand, consumptive material is many, the shortcoming of processing time consuming is especially outstanding.When a novel product of exploitation, need design and make the mould of a large amount of moulds, especially large-scale injection molding in addition, drop into a large amount of funds, spend a large amount of time.The right competition of product transformation has at present changed the competition of die manufacturing cycle and cost into.In a word, along with the maximization of complicated, the size of the type body of moulding and to the requirement in cycle transition, challenge has been proposed for traditional mould mentality of designing and pattern.The mentality of designing and the pattern of traditional moulds are (as Fig. 1): comprise sprue, hot flow path, cover half seat, dynamic model, mould bases, dynamic model seat, push rod, finished parts, guide pillar, cover half.The mold work process is: behind the matched moulds, dynamic model and cover half form die cavity; The injection machine tube that shoots material is injected into die cavity by sprue and hot flow path with the plastics of fusion, becomes finished parts after plastics solidify.After the die sinking, injection machine promotes the push rod of the ejection system in the mould, and finished parts is pushed away mould.So just, obtain a complete product, carry out next one circulation then.In this a kind of production model, the dynamic model seat of mould and cover half seat and dynamic model and cover half are complete secure fit, are not replaceable, and the overall structure that forms mould is called " mould bases ", is a kind of commodity, and factory orders at mould bases.Each product all must the fixing complete mould structure of configuration one cover.Expensive and the long period that certainly will cause mould to make like this.With the auto manufacturing is example, the remodeling of automobile is incremental, the inner trim panels of the door panel of " Santana 2000 " and " Santana 3000 " for example, its size and shape are much the same basically, but when exploitation " Santana 3000 ", the injection mold of producing " Santana 2000 " in the past just is done for, and a large amount of expensive moulds are idle to be very unfortunate.This shows that the mentality of designing of traditional moulds and pattern can not satisfy market demands such as cost is low, the cycle is short at present.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, remodeling is easy, resource utilization is high and development cost is low modular assembling die that is applicable to large-scale injection molding.
A kind of modular assembling die that is applicable to large-scale injection molding of the present invention comprises sprue, thermoplastic road, cover half seat, dynamic model seat, guide pillar, dynamic model, cover half and the liftout attachment that product is pushed away mould; Described sprue and thermoplastic road form feeding-passage; Described sprue is located on the cover half seat; Fixedly connected with the cover half seat in described guide pillar upper end, its lower end and the set guide hole of dynamic model seat are slidingly matched, and the three forms basic mould bases jointly; Described cover half and dynamic model are replaceable modular structure, and the dynamic model module is detachably fixedlyed connected with the dynamic model seat, and the cover half module is detachably fixedlyed connected with the cover half seat, and described cover half module and dynamic model module can form die cavity behind the matched moulds up and down.
Further improvement of the present invention is: described liftout attachment comprises the drive unit oil cylinder of loose piece and loose piece, and described loose piece is fixedlyed connected with the piston rod of oil cylinder and is slidingly matched with the set corresponding aperture of dynamic model module, and the other end of described oil cylinder and dynamic model seat are affixed.
In order to improve the precision of finished parts sharp processing, the upper surface of described loose piece is corresponding consistent with the dynamic model modular type face around it.
For convenient, accurate installation, between described dynamic model module and the dynamic model seat, be located by connecting by alignment pin between cover half module and the cover half seat.Described alignment pin can be cylinder, circular cone or other available type bodies.
Described thermoplastic road is connected with cover half seat and cover half module sealing and communicates with sprue.
Working process of mould tube of the present invention is stated as follows, when matched moulds, and the loose piece indentation, the equal formation die cavity of its end face with the cavity surface of dynamic model module, a material feeding progressive die chamber that shoots material, plastics are condensed into finished parts; When minute mould, loose piece is released, and finished parts is deviate from from mould.Finish do action one time.
The present invention proposes a kind of novel tactic pattern, unitary mould is designed to general part module and the Replacement Part module that can use for a long time, the mold base profile that is about to dynamic model and cover half is made the Replacement Part module of unified standard size.When product needed is retrofited, as long as change dynamic model module and cover half module.If it is, in the time of also need producing the accessory of old maintenance usefulness,, very convenient as long as old dynamic model module and cover half module are changed production because of the needs in market.After being used for a long time with Design Mode of the present invention, comparable traditional mold pattern reduces the cost more than 50%, can shorten die manufacturing cycle more than 60%, and effect is obvious.Overall structure of the present invention is simple, and is easy for installation, also simplified ejection system simultaneously.
