Abstract
The utility model discloses a kind of adjustable molds of core, including mold, core and cavity shell, mold is arranged in cavity shell, through-hole is provided on mold, core is arranged in through-hole, and one end of core is in the interior of mold, it is characterized in that, further include core cushion block, makes mold in molding by cushion block, the one end of core in mold is bonded with mould inner wall.The advantageous effect that the utility model obtains：Solve the problems, such as that product rubber remains by the way that core cushion block is arranged, it is simple in structure, it is easy to operate；Core pad thickness is adjustable, increases the service life of mold, in addition, core cushion block is elastic component, the scope of application is wider；By the way that fixed baffle is arranged, prevent core cushion block from damaging cavity shell.
Description
Technical field
The utility model is related to semiconductor production field, more particularly to a kind of adjustable mold of core.
Background technology
In the prior art, powerful plastic packaging product all carries the lock screw hole with wiring board, and many products are all cloudy surface classes
Type, more such product is based on electrical discharge machining, and the influence of machining accuracy will produce core hole surface and have residual
Rubber, it is serious to influence to install.
Utility model content
For the above defect of the existing technology, the main purpose of the utility model is to overcome the deficiencies in the prior art
Place, discloses a kind of adjustable mold of core, including mold, core and cavity shell, and the mold is arranged in the type
In chamber enclosure, through-hole is provided on the mold, the core is arranged in the through-hole, and one end of the core is in
The mold it is interior, wherein further include core cushion block, by the cushion block make the mold molding when, the core is in institute
The one end stated in mold is bonded with the mould inner wall.
Further, further include fixed baffle, the fixed baffle is arranged on the cavity shell, and is in cavity
Between shell and the core.
Further, the core cushion block is elastic component.
Further, the elastic component is rubber or spring.
Further, the hardness of the core cushion block is less than the hardness of the mold.
The advantageous effect that the utility model obtains：
(1) solve the problems, such as that product rubber remains by the way that core cushion block is arranged, it is simple in structure, it is easy to operate.
(2) core pad thickness is adjustable, increases the service life of mold, in addition, core cushion block is elastic component, is applicable in
Range is wider.
(3) by the way that fixed baffle is arranged, prevent core cushion block from damaging cavity shell.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model product；
Fig. 2 is a kind of structural schematic diagram of the adjustable mold of core of the utility model；
Reference numeral is as follows：
1, mold, 2, core, 3, cavity shell, 4, through-hole, 5, core cushion block, 6, fixed baffle.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality
With novel, it is not used to limit the utility model.
A kind of adjustable mold of core of the utility model, including mold 1, core 2 and cavity shell 3, mold 1 are arranged
In cavity shell 3, through-hole 4 is provided on mold 1, core 2 is arranged in through-hole 4, and one end of core 2 is in mold 1
It is interior, wherein further include core cushion block 5, by cushion block 5 make mold 1 molding when, the one end and mould of core 2 in mold 1
Has the fitting of 1 inner wall, in this way, in mold 1 when injecting glue, glue will not enter core 2 in the contact surface of mold 1, cause
Rubber remains.
In a preferred embodiment, further include fixed baffle 6, fixed baffle 6 is arranged on cavity shell 3, and is in
Between cavity shell 3 and core 2.It can prevent core cushion block 5 from directly being contacted with cavity shell 3 in this way, cavity shell 3 is caused
Damage.
In a preferred embodiment, by being used for a long time, when molding, it will appear gap between core 2 and mold 1, cause
The residual of rubber, there are two types of solutions, and one is the thickness to core cushion block 5 to be adjusted, and pass through increase or reduction type
The thickness of core cushion block 5 is bonded to realize with mold 1；Preferably, the hardness of core cushion block 5 is less than the hardness of mold 1；It is another
Be by core cushion block 5 be elastic component, by the elastic force of elastic component, the moderate thrust to 2 one axial directions of core makes core 2 close
It is bonded always with mold 1 when mould.Wherein, having compressed for elastic component can be adjusted, and elastic component is rubber or spring.
The advantageous effect that the utility model obtains：
(1) solve the problems, such as that product rubber remains by the way that core cushion block is arranged, it is simple in structure, it is easy to operate.
(2) core pad thickness is adjustable, increases the service life of mold, in addition, core cushion block is elastic component, is applicable in
Range is wider.
(3) by the way that fixed baffle is arranged, prevent core cushion block from damaging cavity shell.
It these are only the preferred embodiment of the utility model, be not used for limiting the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of the claims.
