Description
Technical field
The present invention relates to a kind of injection mold and forming method, belongs to injection molding technology field.
Background technology
Injection molding process process includes filling, and -- pressurize -- cooling -- is stripped four-stage.When utilize mould carry out plastics
Part injection production, when the molten plastic from injecting machine material tube enters mold cavity through injection molding machine nozzle, mold runner, is being cooled down
In the stage, during plastics in die cavity are from molten condition to Solid State Transformation, plastic can be shunk.Due to plastic product wall itself
It is thick, filling sequential uneven, the contraction of plastic can be caused inconsistent, cause plastic to be deformed, influence plastic part size and table
Face quality.
The content of the invention
It is an object of the invention to：A kind of air-conditioning moulding injection mold with contraction distortion control and shaping side are provided
Method, plastic is caused to deform to solve existing Shooting Technique, the problem of influenceing plastic part size and surface quality.
To solve the above problems, intend using such a air-conditioning moulding injection mold with contraction distortion control, bag
Punch-pin and cavity plate are included, cavity plate is correspondingly arranged in the surface of punch-pin, and the lower end of cavity plate offers embedding groove, and groove insert is arranged at
In embedding groove, and it is plastic parts moulding area between the bottom of punch-pin and groove insert, is stayed between the top of groove insert and embedding groove
There is gap T, and amounts of contraction of the gap T with plastic vertically is identical, offer spring groove at the top of groove insert, in spring groove
Stage clip is vertically provided with, and the bottom land in embedding groove is held out against at the top of stage clip, sprue bush is vertically additionally provided with cavity plate, and
The runner of sprue bush is connected with plastic parts moulding area.
Present invention also offers a kind of air-conditioning moulding forming method with contraction distortion control, specific method are as follows：
In use, by sprue channel to plastic parts moulding area filled plastics, under injection pressure effect, die plate insert overcomes stage clip
Pressure retreat gap T distances, and carry out pressurize until cooling stage, when filling plastic finishes, and injection pressure reduces, plastic
Begin to cool down, shrink, and in the presence of stage clip, die plate insert starts to move with shrinkage of injection molded parts, and gap T becomes larger, simultaneously
Plastic surface is extruded, until cooling terminates.Due to being acted on by die plate insert external force, its internal stress becomes plastic
Change, regular contraction is changed into by unordered contraction, so as to change the defects of shrinkage of injection molded parts deformation causes.
Compared with prior art, the present invention is improved on the basis of existing cavity plate so that in injection moulding process, in cavity plate
Die plate insert can move with the flexible of plastic parts moulding process, and plastic by die plate insert external force due to being acted on, inside it
Stress changes, and is changed into regular contraction by unordered contraction, so as to change the defects of shrinkage of injection molded parts deformation causes.
Brief description of the drawings
Fig. 1 is the sectional view of mould of the present invention；
Fig. 2 is the partial enlarged drawing of mold work main part in Fig. 1.
Embodiment
Embodiment：
Referring to Figures 1 and 2, the present embodiment provides a kind of air-conditioning moulding injection mold with contraction distortion control, including convex
Mould 1 and cavity plate 2, cavity plate 2 are correspondingly arranged in the surface of punch-pin 1, and the lower end of cavity plate 2 offers embedding groove 21, and groove insert 3 is set
It is placed in embedding groove 21, and is plastic parts moulding area 4, the top of groove insert 3 and edge between the bottom of punch-pin 1 and groove insert 3
Leave gap T between caulking groove 21, T refers to the width dimensions in gap, not reference, and gap T and plastic are vertically
Amount of contraction is identical, and the top of groove insert 3 offers spring groove 31, and the interior edge of spring groove 31 is vertically provided with stage clip 6, and stage clip 6
Top hold out against in being vertically additionally provided with sprue bush 7, and the runner and plastic of sprue bush 7 in the bottom land of embedding groove 21, cavity plate 2
Shaping area 4 is connected.
Its forming method is as follows：In use, made by sprue channel to the filled plastics of plastic parts moulding area 4 in injection pressure
Under, die plate insert 3 overcomes the pressure of stage clip 6 to retreat gap T distances, and carries out pressurize until cooling stage, works as filling plastic
Finishing, when injection pressure reduces, plastic begins to cool down, shunk, and in the presence of stage clip 6, die plate insert 3 is opened with shrinkage of injection molded parts
Begin to move, gap T becomes larger, while extrudes plastic surface, until cooling terminates.Plastic is due to by die plate insert
3 external force act on, and its internal stress changes, and are changed into regular contraction by unordered contraction, so as to change shrinkage of injection molded parts deformation
The defects of causing.
