Description
Technical field
The present invention relates to semiconductor production field, more particularly to a kind of adjustable mould of core.
Background technology
In the prior art, for powerful plastic packaging product all with the lock screw with wiring board, many products are all cloudy surface classes
Type, more such product is based on electrical discharge machining, and the influence of machining accuracy can produce cored hole surface and have residual
Rubber, serious meeting influence installation.
The content of the invention
The defects of existing for above prior art, it is a primary object of the present invention to overcome the deficiencies in the prior art it
Place, discloses a kind of adjustable mould of core, including mould, core and die cavity shell, the mould are arranged on the die cavity
In shell, through hole is provided with the mould, the core is arranged in the through hole, and one end of the core is in institute
The interior of mould is stated, wherein, in addition to core cushion block, making the mould by the cushion block, the core is described in matched moulds
One end in mould is bonded with the mould inner wall.
Further, in addition to fixed dam, the fixed dam are arranged on the die cavity shell, and are in die cavity
Between shell and the core.
Further, the core cushion block is elastic component.
Further, the elastic component is rubber or spring.
Further, the thickness of the core cushion block can increase or reduce.
Further, the hardness of the core cushion block is less than the hardness of the mould.
The beneficial effect that the present invention obtains：
(1) it is simple in construction by setting core cushion block to solve the problems, such as that product rubber remains, it is easy to operate.
(2) core pad thickness can adjust, and add the mold use life-span, in addition, core cushion block is elastic component, be applicable
Scope is wider.
(3) by setting fixed dam, prevent core cushion block from damaging die cavity shell.
Brief description of the drawings
Fig. 1 is the schematic diagram of product of the present invention；
Fig. 2 is a kind of structural representation of the adjustable mould of core of the present invention；
Reference is as follows：
1st, mould, 2, core, 3, die cavity shell, 4, through hole, 5, core cushion block, 6, fixed dam.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with the accompanying drawings and embodiment pair
The present invention is described in further detail.It should be appreciated that specific embodiment described herein is only to explain the present invention, and do not have to
It is of the invention in limiting.
A kind of adjustable mould of core of the present invention, including mould 1, core 2 and die cavity shell 3, mould 1 are arranged on type
In chamber enclosure 3, through hole 4 is provided with mould 1, core 2 is arranged in through hole 4, and one end of core 2 is in the interior of mould 1,
Wherein, in addition to core cushion block 5, mould 1 is made in matched moulds by cushion block 5, the one end of core 2 in mould 1 and the inwall of mould 1
Fitting, so, in mould 1 during injecting glue, glue will not enter core 2 with the contact surface of mould 1, causing rubber residual
Stay.
In a preferred embodiment, in addition to fixed dam 6, fixed dam 6 is arranged on die cavity shell 3, and is in
Between die cavity shell 3 and core 2.It so can prevent core cushion block 5 from directly being contacted with die cavity shell 3, die cavity shell 3 is caused
Damage.
In a preferred embodiment, by long-term use, during matched moulds, gap occurs between core 2 and mould 1, causes
The residual of rubber, there are two kinds of solutions, a kind of is that the thickness of core cushion block 5 is adjusted, and passes through increase or reduction type
The thickness of core cushion block 5 is bonded to realize with mould 1；Preferably, the hardness of core cushion block 5 is less than the hardness of mould 1；It is another
It by core cushion block 5 is elastic component to be, by the elastic force of elastic component, the moderate thrust to 2 one axial directions of core, is closing core 2
It is bonded all the time with mould 1 during mould.Wherein, have compressed for elastic component can be adjusted, and elastic component is rubber or spring.
The beneficial effect that the present invention obtains：
(1) it is simple in construction by setting core cushion block to solve the problems, such as that product rubber remains, it is easy to operate.
(2) core pad thickness can adjust, and add the mold use life-span, in addition, core cushion block is elastic component, be applicable
Scope is wider.
(3) by setting fixed dam, prevent core cushion block from damaging die cavity shell.
Presently preferred embodiments of the present invention is these are only, is not used for limiting the practical range of the present invention；If this is not departed from
The spirit and scope of invention, modify or equivalent substitution to the present invention, all should cover the protection in the claims in the present invention
Among scope.
