Description
Technical field
The utility model is related to technical field of mold, and in particular to cut off automatically in a kind of mobile phone mould of application in a mold
Gate mechanism.
Background technology
Mould is indispensable important equipment in injection molding.Injection molding is by the plastic material high speed of the state of hot melt
Be injected into the closed molding space in mould with required shape, wait after plastic material cools and solidifies, opening mould will be solid
The plastic cement machining object ejection of change, the method to obtain products formed.Because injection molding forming method has, shaping expense is low, molding cycle
The features such as short, forming process is simple and is easy to the plastic cement products of forming shape complexity, therefore in plastic cement products manufacture field application
It is extremely widespread.
In injection molding, plastic has a running gate system, for example：Style big water gap directly enters after water, such formed product,
Inevitably its mouth of a river is removed, by traditional method, after shaping, the mouth of a river must be removed.Conventional art is
Using removing by hand or being directly equipped with water gap cutting device in a mold, such as using by hand, increasing is taken time and effort, so not only significantly
Extend manufacture cycle, and efficiency is low, and labor intensity is big, makes employee's fatiguability；Water dividing gap dress is equipped with a mold as used
Put, existing water gap cutting device structure is complex, majority is the purpose that automatic water gap cutting is realized using inclined-block linkage mechanism,
The mechanism is complex, and appearance and size is big, causes the structure of mould excessively complicated, and manufacturing cost is high.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is there is provided a kind of structure design is simple and reliable, small volume, easily
Gate mechanism is cut off in the mobile phone mould at the mouth of a river automatically in installation mold, can quickly cut off.
To achieve the above object, technical scheme provided by the utility model is：The automatic excision mouth of a river in a kind of mobile phone mould
Mechanism, it includes miniature oil cylinder and the cutting knife being arranged on the piston rod of the miniature oil cylinder, and the cutting knife includes pressing from top to bottom
Socket part, diminution portion and the knife bar portion being sequentially connected with, the upper surface of the socket part is provided with mutually fits with the piston rod
The sleeve joint hole matched somebody with somebody, the cross-sectional profile profile in the knife bar portion be it is square, the lower end in the knife bar portion provided with angle of inclination be 43~
48 degree of inclined plane formation cutter head.
As a kind of improvement of the present utility model, the cross-sectional profile profile of the socket part is circle.
As a kind of improvement of the present utility model, the angle of inclination of the inclined plane is 45 degree.
The beneficial effects of the utility model are：The utility model smart structural design, rationally, directly driven by miniature oil cylinder
Dynamic cutting knife stretches to realize the purpose of water dividing gap, and simple structure, small volume occupies little space, it is easy in mould；And
Knife bar portion is square so that water dividing gap action is more smoothly, and moving equilibrium is good, and reliable high, overall structure is simple in addition, effectively
Simplify mould structure, reduce volume, reduce die cost, improve production efficiency, used beneficial to being widely popularized.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is the structural representation in knife bar portion in the utility model.
Fig. 3 is structural representation when the utility model is used.
Embodiment
Automatic excision gate mechanism in a kind of mobile phone mould provided referring to Fig. 1, Fig. 2 and Fig. 3, the present embodiment, it includes micro-
Type oil cylinder 1 and the cutting knife 2 being arranged on the piston rod of the miniature oil cylinder 1, the cutting knife 2 include successively connecting by order from top to bottom
Socket part 21, diminution portion 22 and the knife bar portion 23 connect, the upper surface of the socket part 21 is provided with to be adapted with the piston rod
Sleeve joint hole, preferably, the cross-sectional profile of the socket part 21 is preferably contoured as circle, structural strength is big.
The cross-sectional profile profile in the knife bar portion 23 is square so that water dividing gap acts more smoothly, moving equilibrium
It is good, it is reliable high.The lower end in the knife bar portion 23 forms cutter head provided with angle of inclination a for 43~48 degree of inclined plane 231, preferably
, the angle of inclination of the inclined plane 231 is 45 degree, and excision effect is good.Preferably, being also provided with width in the end of cutter head
0.15 millimeter of plane 232 so that the mouth of a river 3 is separated with injection moulded products 4.
In use, the correspondence mouth of a river 3 and the junction position of injection moulded products 4 will cut off water automatically in mobile phone mould of the present utility model
Mouth mechanism is arranged on mould, it is necessary to during water dividing gap 3, is directly driven cutting knife 2 by miniature oil cylinder 1 and is stretched and realizes automatic water-stopping
The purpose of mouth, operation is simple, and good operating stability greatly improves production efficiency.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.In addition, to the greatest extent
Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Constitute any limitation.As described in the utility model above-described embodiment, using other obtained from same or similar structure
Mould, in the utility model protection domain.
