Description
Technical field
The utility model belongs to technical field of mold, particularly relates to evenly cooling elongated handles injection mold of a kind of minimizing distortion.
Background technology
In commodity were produced, more and more obvious with the phenomenon of moulding Dai Gang, because plasthetics has easy retractility, it was of all kinds to cause plasthetics to form, fantastic part shape, and this manufactures and designs to plastic mould and has brought sizable challenge.Plasthetics also need be taken into account functional requirement simultaneously, all will reach certain requirement such as tensile yield strength, elongation at break, bending strength, elastic modelling quantity, impact strength, heat resisting temperature, heat distortion temperature etc.; And the requirement of some aesthetic appearance of product is also quite special, needs high minute surface, solarization line face, both artistic and practical etc. such as some.Particularly will face these problems in the production of elongated handles, whether intensity is enough during such as use, whether the outward appearance feel is good.
Analyze from the production process of this product with these problems, draw to draw a conclusion, the profile of product is elongated, and owing to will increase the feel of handle, will there be concave point on its circle shape surface, so in process of production, cannot not do roundly can appear in product, jagged, shrinks, and that cooling effect can appear in mould is bad, and then causes continuing the problems such as production.
The utility model content
Technical problem to be solved in the utility model provides evenly cooling elongated handles injection mold of a kind of minimizing distortion, can guarantee and product quality.
The technical scheme that its technical problem that solves the utility model adopts is: evenly cooling elongated handles injection mold of a kind of minimizing distortion is provided, comprise dynamic model, the first side slide shaping mechanism, oil cylinder core-pulling mechanism and the second side slide shaping mechanism, described dynamic model bilateral symmetry is equipped with the first side slide shaping mechanism and the second side slide shaping mechanism, oil cylinder core-pulling mechanism is installed in the first side slide shaping mechanism and the second side slide shaping mechanism outside separately, on the dynamic model between the first side slide shaping mechanism and the second side slide shaping mechanism product is installed.
On the described dynamic model cover half is installed.
Described product has 2 at least.
Beneficial effect
The utility model has guaranteed that Design of Dies has carried out professional mold flow analysis in strict accordance with product structure characteristic, the CAD/CAE software of application of advanced is with the mold cavity layout of product, gate location, exhaust, evenly cooling system, cold burden and ejection system perfect adaptation be in one.The virtual emulation means of science have showed later stage actual process condition and situation in advance, and the common process gimmick that stopped repetition test, repeats to revise has promoted design efficiency, simultaneously the stability of product quality is laid a solid foundation.
Efficient mould structure technology: this mould has adopted two succinct template die structures, and the precision components such as active and inactive mold core and core-pulling mechanism form.Adopted thus a width of cloth mould to go out the structure of the two groups of two-way slide blocks that crash in two caves, long core-pulling mechanism is divided into two-end core-loosing, in interleave and wear the location, increase stability, high rigidity and the global consistency of mould inside structure.
The above slipper block loose core power set of 100mm have adopted the more stable oil cylinder kind of drive, and the controllability of oil cylinder signal has satisfied the action that first die sinking is loosed core again.Thereby the stability of the mold mechanism that guarantees, the flexibility that has improved core-pulling mechanism, slide block bumps that to wear the face position more accurate when making mould closed, has improved serious overlap, burr phenomena.Larger loose core of oil cylinder power has also satisfied goods stronger enclasping force to die cavity when hot shrinkage effect is loosed core, so sliding block core-pulling mechanism has adopted the SKD61 materials of hardness up to 50 degree.
This product is in forming process, the temperature of mould also along with filling the time temperature of plastic cement pass to mold cavity, the temperature of the growth mould of production time is also constantly being increased, in this case, elongated core rod has adopted the mode of circulation water flowing to cool off now, controlled the temperature of mould, product quality, a kind of assurance that efficient improves.Filling equal pressure when mould is bearing injection has proposed strict requirement to mold mechanism and material.Therefore, this product mold die cavity has adopted German import NAK80 plastic mould special steel, but its excellent ductility, high temperature fatigue cracking, protects excellent performance such as impacting fission, plastic deformation, tensile strength polishability, corrosion resistance and provide strong guarantee for mould.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
Such as Fig. 1 ~ shown in Figure 2, a kind of minimizing distortion is cooling elongated handles injection mold evenly, comprise dynamic model, the first side slide shaping mechanism 1, oil cylinder core-pulling mechanism 3 and the second side slide shaping mechanism 4, described dynamic model bilateral symmetry is equipped with the first side slide shaping mechanism 1 and the second side slide shaping mechanism 4, the first side slide shaping mechanism 1 and the second side slide shaping mechanism 4 outside is separately installed on the dynamic model between oil cylinder core-pulling mechanism 3, the first side slide shaping mechanisms 1 and the second side slide shaping mechanism 4 product 2 is installed.
On the described dynamic model cover half is installed.
Described product 2 has 2 at least.
When the utility model possesses the particular manufacturing craft material of rational mould structure, function admirable, the processing of mould is had higher requirement.In Technology for Heating Processing, 3 times vacuum nitriding is processed, and makes die surface hardness reach the height of 45 degree.48 hours room temperature ageing pattern has guaranteed mould strength and life-span fully, can obtain outstanding suface processing quality.Especially the type shape of this mold cavity concave-convex surface guarantees feel, and it is public to have adopted advanced numerical control machining center to carve copper, carries out accurate spark machine discharge processing active and inactive mold core again.
The product material is ABS, and raw material was dried 4 hours with 85 ℃～90 ℃ temperature first; The temperature of stationary mould for mould is 5 ℃, and the temperature of dynamic model is 5 ℃; During injection, 255 ℃ of barrel temperatures, injection pressure 110Mpa, injection speed 10m/s; 5 seconds inject time, 6 seconds dwell times, 20 seconds cool times; Whole injection cycle 47 seconds altogether.
