Abstract
The utility model relates to a mould and discloses a precise mould for gradual injection molding. The precise mould comprises a front mould core and a back mould core which have the same outlines and are mutually and closely combined to form a hollow molding cavity, wherein the outer parts of the front mould core and the back mould core are respectively sleeved with a front template and a back template which are mutually matched; the front template is fixed on a panel and the back template is arranged on a bottom plate, wherein a slide is arranged on the closely-combined front mould core and back mould core, and a driving device for driving the closely-combined front mould core and back mould core to move up and down in the front template and the back template is connected to the slide; a thick part of the mould cavity is arranged at the upper end of the front mould core and the opening of the thick part is upward; and the panel is fixedly provided with an insert which is matched with the opening. The precise mold disclosed by the utility model has the advantage that manufactured products do not shrink and are not lack of adhesive.
Description
Technical field
The utility model relates to mould, the product that especially the relates to a kind of production progressively injection moulding precision die with starved that can not shrink.
Background technology
In recent years; Develop rapidly and general and engineering plastics improving constantly along with plastics industry at aspects such as intensity and precision; The range of application of plastic products is also in continuous expansion, as: household electrical appliance, instrument and meter, construction equipment; Various fields such as auto industry, haberdashery and hardware, the shared ratio of plastic products just rapidly increases.A working of plastics reasonable in design often can replace a plurality of traditional metal parts.Mould is a kind of instrument of producing plastic products.It partly is made up of several groups of parts, in this combination shaping mold cavity is arranged.During injection moulding, the mould clamping is on injection machine, and molten plastic is injected in the shaping mold cavity; And in the chamber cooling and shaping, upper and lower mould separately ejects goods via ejection system and to leave mould from die cavity then; Last mould closure again carries out injection moulding next time, and whole injection moulding process circulation is carried out.Because the easy shrinkage (like PE) of plastics, plastic products all can deform at cooling stage.Under this condition, the profile that will change over type die adapts to the geometrical deviation of plastic products, and for example: straight although the plastic products wall keeps, its reference center has departed from 10mm; Can raise mold base, to adjust the amount of contraction of this distortion.But the plastic products that have are just thicker at a certain position, and other position is thinner, and plastic products add man-hour in injection moulding; In any case prevention; Claim again to shrink because amount of contraction is bigger, and the phenomenon of size decreases can appear in this position in its thicker position; Perhaps injection device can not be filled with the phenomenon that starved appears in this position with the plastics that melt, and is substandard products or waste product thereby make the new product of producing.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model purpose is to provide a kind of product of production progressively injection moulding precision die with starved that can not shrink.
The utility model is realized through following technical measures; A kind of progressively injection moulding precision die; Emptyly in when comprising the identical mutual driving fit of outline be die behind the front mould Renhe of shaping mold cavity; The outside of die is equipped with the front template and the rear pattern plate of mutual coupling respectively behind the front mould Renhe, and said front template is fixed on the panel, and said rear pattern plate is arranged on the base plate; Wherein, Die is provided with the row position behind the front mould Renhe of driving fit; Be connected with one on this row position and drive the drive unit that die moves up and down behind the front mould Renhe of driving fit in said front template and rear pattern plate; The upper end of die and for opening makes progress before thick of said die cavity is arranged on is fixed with one and the mold insert that is complementary of this opening on the said panel.
Preferred cylinder of said drive unit or oil cylinder.
As a kind of optimal way, said drive unit is two that symmetry is installed.
As a kind of optimal way, be fixed with a backing plate on the said panel, be provided with the mold insert that is complementary with said opening in this backing plate.
The utility model is done a mold insert (it is motionless that mold insert is fixed on panel) according to the position (position of die cavity) of thick of product at front mould, makes the thickness of the glue of the each several part of product when beginning to inject molten plastic glue average.When changeing pressurize, through both sides oil cylinder pulling row position, the forward and backward die that drives driving fit moves down, and fills with molten plastic glue in the moving process again, progressively enriches the thickness portion of product.Thereby so just can solve the problem of shrink or starved.

Fig. 2 is the tangent plane structural representation of the utility model embodiment product.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further explain.
A kind of progressively injection moulding precision die; The preceding die 6 and back die 9 of the die cavity of empty shape for product 8 in when comprising the identical mutual driving fit of outline; The outside of preceding die 6 and back die 9 is equipped with the front template 4 and rear pattern plate 10 of mutual coupling respectively; Front template 4 is fixed on the panel 2 through a backing plate 3, and there is the injection hole 1 that communicates with die cavity panel 2 and top; Rear pattern plate 10 is arranged on the base plate 11; Wherein, The preceding die 6 of driving fit is provided with symmetrical row position 7 with back die 9; Row is connected with oil cylinder 5 respectively on the position; The preceding die 6 of driving fit and back die 9 are driven and can in front template 4 and rear pattern plate 10, be moved up and down by oil cylinder 5, and thick 801 of product processed 8 in the die cavity upper end of preceding die 6 and be upward opening, are provided with one and the mold insert that is complementary of opening in the backing plate 3.
Before the injection moulding, the preceding die 6 of driving fit is positioned at front template 4 and rear pattern plate 10 tops with back die 9, and the opening of preceding die 6 is near backing plate 3; This moment, mold insert embedded in the opening, and the interval in the die cavity is a similar thickness all, and the thickness of the glue of the each several part of product 8 is average when beginning to inject molten plastic glue; When changeing pressurize, through both sides oil cylinder 5 pulling row positions 7, the preceding die 6 that drives driving fit moves down with back die 9; Fill with the plastic cement of fusion in the moving process again, progressively enrich the thickness portion 801 of product 8.Thereby produce qualified product 8.
More than be to the utility model progressively the injection moulding precision die set forth; Be used for helping to understand the utility model; But the embodiment of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the utility model.
