Description
Technical field
The invention belongs to technical field of plastic, be specifically related on injection machine, once finish injection moulding with a mold---the particular manufacturing craft of blow molded plastic hollow container shaped article is mainly used on the common injection machine.
Background technology
In the blow molded product molding process of plastics, traditional handicraft adopts and extrudes---blow molding method.The product that this method is produced, the protrusion crack that appearance can not be eliminated on product surface makes product surface not attractive in appearance, smooth.And unnecessary leftover pieces appear inevitably, cause the waste of raw materials for production and the cost of increase formed product.
Owing to above reason, developed a kind of two-step method and annotated---blow the method for hollow molding blow molded product.Its method is to inject parison earlier, and heating is blown into the hollow container product on the blow moulding machine forwarding to, and in this processing method, production link is many, and equipment investment is big, and complex forming technology, automaticity are not high.Recently,, invented a kind of new plastic hollow vessel forming method, seen that publication number is the Chinese invention patent of CN1562610A in order to overcome above defective.It mainly is applicable in the horizontal parallel-moving type mould of two stations.This method is that injection mold separates with blow mold, and the parison of injection moulding is transferred to the outer blow mold of injection machine mould and just carried out blowing formation product after the injection mold injection mo(u)lding.This method needs the injection machine of special construction, the controlling of production process difficulty, and one-time investment is big, and mould structure is not compact, and is bad to neutrality, and product quality is not easy to guarantee.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art part, a kind of mould that can once finish injection moulding, blow molding plastic product on common injection machine is provided.
For achieving the above object, technical scheme of the present invention is as follows: the mould of direct notes, blowing material hollow container shaped article comprises injection mould assembly and blow molding die assembly; The injection mould assembly comprises dynamic model and the cover half that above-below direction is provided with, and dynamic model is by one group of driving mechanisms control itself and cover half folding in vertical direction; Cover half is provided with at least one row's injection hole, is fixed with the plug that at least one row has the blowing mouth on the dynamic model, and is corresponding one by one with injection hole on the cover half; The blow molding die assembly comprises two templates, lays respectively at the both sides of above-mentioned plug, and the medial surface of each template is provided with at least one product die orifice of lining up, and is corresponding one by one with each plug, and the folding of two template horizontal directions is organized driving mechanisms control by another.Mould of the present invention can be directly installed on the common injection machine, and after injection mould was finished the parison injection moulding, injection mould was opened, and then the blow molding die matched moulds, carries out blow molding.
But be provided with the push pedal that a vertical direction moves above the above-mentioned dynamic model, plug runs through this push pedal, and supports blow molding die on the push pedal.
The position of running through of corresponding plug is provided with notes-blowing boss above the above-mentioned push pedal.
Following and the gas board component of above-mentioned dynamic model is connected.
Adopt mould of the present invention, can be implemented in the injection moulding of once finishing plastic product on the common injection machine with a mold---blow molding, do not need to increase extras, invest little, simple to operate, automaticity and production efficiency height, quality more guarantees.Real realization injecting preform and hollow container blow molding are all finished on same mould.The present invention has the following advantages compared with the prior art: 1, directly use common injection machine, the production technology link that overcomes two step method and two station methods is many, the shortcoming that equipment investment is big; 2, production automation degree and production efficiency height; 3, The mould features compact structure is installed easily, and operation is easy to maintenance; 4, one step finished from the parison to goods, and good to neutrality, product surface does not have crack, the easier assurance of product quality.

Now the invention will be further described in conjunction with the accompanying drawings and embodiments:
The specific embodiment
Shown in Fig. 2,3, the present invention includes injection mould assembly and blow molding die assembly.The injection mould assembly comprises dynamic model 4 and the cover half 5 that above-below direction is provided with.Dynamic model 4 is by one group of driving mechanisms control itself and cover half 5 folding in vertical direction.Cover half 5 is provided with row's injection hole 9, and injection hole is communicated with notes mouth 51 on the cover half 5.Be fixed with a row on the dynamic model 4 and have the plug 1 of blowing mouth, corresponding one by one with injection hole 9 on the above-mentioned cover half 5.But be provided with the push pedal 8 that a vertical direction moves above the dynamic model 4, be used for finished product is released, plug 1 runs through this push pedal 8, and supporting blow molding die assembly 2 on the push pedal 8.Blow molding die assembly 2 is made up of two templates 10, lays respectively at the left and right sides of the plug 1 on the dynamic model 4, by the folding on one group of hydraulic drive mechanism, 3 both horizontal directions of control.The medial surface of each template 10 is provided with one and lines up product die orifice 101, and is corresponding one by one with each plug 1.Following and the gas board component 41 of dynamic model 4 is connected.The position of running through of corresponding plug 1 is provided with notes-blowing boss 81 above the above-mentioned push pedal 8.
As shown in Figure 1, processing method comprises injection moulding, the blowing process segment.Injection phase is made up of following operation: injection machine matched moulds 11, parison injection moulding 12 and mold open 13; The blowing stage is made up of following operation: blow molding die closure 21, and blowing moulding 22, blow molding die die sinking 24 is given plasticizing 23 and product and is ejected 25.Detailed process is as follows:
As Fig. 2, Fig. 4 and shown in Figure 5, injection phase comprises: the injection mould closure: dynamic model 4 advances to cover half 5 from bottom to top, and plug 1 is inserted in the injection hole 9, and injection hole is to mandrel outer surface injection moulding blank 7.After injection moulding finished, mold open: dynamic model descended, and finished injection moulding thereby separate with cover half.
Extremely shown in Figure 8 as Fig. 6, the blowing stage comprises: under the driving of hydraulic structure 3, two template 10 closures of blow molding die, the finished product die orifice 101 of left and right sides template closes up, jointly every plug 1 is enclosed in the center, to plug 1 inner the air blowing, the blank of its outer surface expands and is full of the space that left and right sides die orifice 101 surrounds, and forms moulded products 6 by the gas board component.As shown in Figure 9, after blowing was finished, two templates 10 were separated, and push pedal 8 is moved vertically upward, thereby ejects moulded products 6, and injection machine begins to carry out next injection moulding more then---the blowing circulation.
If take a mould to arrange multi-cavity mold more, utilize this mould to produce hollow container, in the cycle, can produce 16～32 hollow containers a fabrication cycles, to enhance productivity greatly, production cost reduces greatly.
Adopt mould of the present invention, the production technology link that can overcome two step method and two station methods is many, the shortcoming that equipment investment is big, The mould features compact structure is installed easily, operating maintenance is simple, one step finished from the parison to goods, and good to neutrality, product surface does not have crack, the easier assurance of product quality has improved automaticity and production efficiency greatly.
