It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, the embodiment of the present invention includes：
Embodiment 1
Present invention is disclosed a kind of easily demoulding injection molds for being used to prepare the internal moulding with through-hole, including：Left mould
Tool 1, right mould tool 2, the left arm of force 3, the right arm of force 4, liftout attachment 5 and plug 6；Wherein, 2 opposite shape of the left mould tool 1 and right mould tool
At injection mold cavity 7；The left mould tool 1 is fixedly connected backwards to a middle side part of the injection mold cavity 7 with the left arm of force 3, described
Right mould tool 2 is fixedly connected backwards to a middle side part of the injection mold cavity 7 with the right arm of force 4；The liftout attachment 5 is installed respectively
In left mould tool 1 and right mould tool 2 close to the side of the left arm of force 3 and the right arm of force 4.
Left mould tool 1 and right mould tool 2 are mounted on insert 8 towards the side of the injection mold cavity 7, in the insert 8
Threaded hole containing internal thread.
The plug 6 include mandrel 61 and barred body 62, the mandrel 61 be mounted on barred body 62 one end, diameter be less than etc.
In the diameter of the barred body, which is cylinder, and surface carries the threaded hole screw-thread fit coordinated with first insert
External screw thread, the barred body 62 is cylindrical or multi-edge column-shaped.The sum of length of two barred bodies 62 is equal to left mould tool 1 and the right side
The width for the injection mold cavity 7 that mold 2 is formed after molding.When left mould tool 1 and right mould 2 molding of tool, the barred body end phase of two plugs
Mutually docking forms an entire barred body, injection melting sizing material, the inside meeting of moulding after cooling into injection mold cavity 7 at this time
Band can set the position of plug there are one through-hole according to actual needs, to obtain corresponding through-hole position moulding.
In addition, the junction periphery of the plug 6 and the insert 8 is also equipped with the elastic seal ring that thickness is 2~5mm, pass through bullet
Property sealing ring setting so that the end of the through-hole inside injection member be chamfering form, keep through-hole more smooth.By in left mould
Have and right mould has interior setting insert, on the one hand, can be by the structure of the blind hole in the second insert of replacement, meeting moulding has
The requirement of different through-hole structures；On the other hand, when occur plug and abrasion after, can be by replacing corresponding insert more
Plug is changed, die cost is reduced.
The liftout attachment 5 includes baffle 51 and mandril 52, and the middle part of the baffle 51 carries through-hole, and the baffle 51 is logical
It crosses its through-hole to be nested on the corresponding left arm of force 3 or the right arm of force 4, bottom end is fixed on die apparatus, the mandril 52
Horizontal positioned, one end is horizontally fixed on the baffle 51, and the other end has 1 or right mould tool 2 through the left mould, meanwhile,
Band is useful for the jacket casing 10 that the mandril 52 extends into or out in the left mould tool 1 or right mould tool 2.It is carried on every group of liftout attachment
Two groups of mandrils, every group of mandril are distributed in the upper and lower part of the through-hole of corresponding baffle 51, for uniformly ejecting moulding, realize
Demoulding.
The top side of left mould tool 1 or right mould tool 2 is respectively provided with a hole for injecting glue 11, passes through two hole for injecting glue 11
Design, on the one hand improves injecting glue rate, improves production efficiency, and on the other hand, the uniform injecting glue in both sides can improve injection mould
Intracavitary melts the uniformity of sizing material distribution, to improve product quality.
In left mould tool 1 or the top side of right mould tool 2, aspirating hole is also distributed with positioned at the inside of the hole for injecting glue 11
12, for extracting the air in injection mold cavity out, prevents moulding surface from carrying bubble, influence presentation quality.
The easily demoulding injection mold for being used to prepare the internal moulding with through-hole of the present invention, its working principle is that：
Plug flat spin is mounted in the insert of left mould tool and right mould tool, molding, the other end insertion of two plugs is made to be connected to
Barred body end docking in the blind hole of the second insert in right mould tool；By the hole for injecting glue 11 on left mould tool and right mould tool to injection mould
Injection melting glue in chamber 7, while being extracted out the air in injection mold cavity 7 by the aspirating hole 12 on left mould tool and right mould tool；
After filling, cooling device is opened（In left mould tool and right mould tool）, so that moulding is uniformly cooled down, then start die sinking system
System, makes the left arm of force of mold and the right arm of force open to the left, to the right respectively, during opening, the left arm of force and right arm of force difference
It drives corresponding baffle left mould tool and right mould to have to both sides to move, in the process, since mandril is fixed by baffle, because
This, mandril has relative to left mould or right Die and mould plate generates forward thrust to moulding, to realize that moulding demoulds.
A kind of easily demoulding injection mold for being used to prepare the internal moulding with through-hole of the present invention, it is simple in structure, if
Meter is reasonable, the design docked by two plugs so that forms the through-hole of excellent in mechanical performance inside moulding, and molds
When moulding be easier to demould in the middle part of the mold；By the design of liftout attachment, realize that moulding uniformly demoulds.Gained moulding
Surface is smooth, pore-free, and interior bone structure is intact, zero defect, excellent combination property.
In the description of the present invention, it should be noted that the instructions such as term "upper", "lower", "left", "right", "inner", "outside"
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings or the invention product using when usually put
Orientation or positional relationship, be merely for convenience of description of the present invention and simplification of the description, do not indicate or imply the indicated device
Or element must have a particular orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, and those skilled in the art is come
It says, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any modification made by is equal
Replace, improve etc., it should all be included in the protection scope of the present invention.
