Description
Technical field
The utility model relates to a kind of mold-opening structures, particularly relate to a kind of structure that can postpone line position die sinking.
Background technique
It is well known that the Slide mechanism of mold is that can obtain side core-pulling or undercut and homing action to haul out
The mechanism of the positions such as product back-off, sunken.It is used using molding die sinking movement, and the diagonal brace tip and sliding block is made to generate relative motion
Trend makes sliding block along die sinking direction and two kinds of forms of motion of horizontal direction, is allowed to be detached from overhead kick.
When injection molding, since product structure is limited, before product is viscous when mould, line position is needed to postpone line position, to force line position that will produce
Product are drawn to rear mold.Otherwise will affect injection moulding process, but occur at present line position delay mold-opening structure in the prevalence of structure not
Rationally, postpone insufficient disadvantage, and this is the major defect for traditional technology.
Utility model content
A kind of technical solution adopted in the utility model are as follows: line position delay mold-opening structure comprising upper cores, lower mode
And line position sliding block, wherein the upper cores be arranged above the lower mode, between the upper cores and the lower mode formed one at
Type chamber, the line position sliding block are arranged between the upper cores and the lower mode, bullet block are respectively arranged in the upper cores two sides, from this
Bullet block top surface is recessed with downwards spring cavity, is provided with spring in the spring cavity, spring setting the upper cores and the bullet block it
Between, the bullet block bottom surface it is concave up be equipped with butt hole, it is corresponding with the bullet block, be recessed with card slot at the top of the line position sliding block,
Upward convex on the bottom surface of the card slot to be equipped with plush copper, which is plugged in the butt hole, is fixedly installed at the top of the plush copper soft
Property gasket, which is made of silica gel material, which has arcuation outer surface.
When specific implementation, which is connected with link block, and inclination guide hole is offered on the link block, should
Inclination guide post is equipped in inclination guide hole.
The utility model has the following beneficial effects: when utility model works, when upper cores, the molding of lower mode, bullet
Bullet block is promoted in card slot and blocks line position by spring, this moment, bullet block can be made smoothly to be stuck in the plush copper of card slot by arcuation outer surface
On, while alleviating by flexible gasket the pressing force of bullet block, when die sinking, upper cores, lower mode are initially separated, and bullet block is also opened
The disengaging line position to begin slowly, since card slot is straight body slot, so bullet block is also keeping off line position when upper cores, lower mode separate, no
Line position is allowed to be opened, when upper cores, lower mode are separated into preset distance, bullet block has also completely disengaged card slot, and at this moment line position can
To be opened safely, and then have the function that line position delay die sinking.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model link block.
Fig. 3 is the structural schematic diagram of the utility model plush copper.
Specific embodiment
As shown in Figures 1 to 3, a kind of line position postpones mold-opening structure comprising upper cores 10, lower mode 20 and line position sliding block
30, wherein the upper cores 10 are arranged above the lower mode 20, and a molding is formed between the upper cores 10 and the lower mode 20
Chamber 40.
The line position sliding block 30 is arranged between the upper cores 10 and the lower mode 20, is respectively set in 10 two sides of upper cores
There is bullet block 50.
It is recessed with spring cavity 51 downwards from 50 top surface of bullet block, is provided with spring 60 in the spring cavity 51, which sets
It sets between the upper cores 10 and the bullet block 50.
It is concave up equipped with butt hole 52 in 50 bottom surface of bullet block.
As shown in figure 3, it is corresponding with the bullet block 50, it is recessed with card slot 31 at the top of the line position sliding block 30, in the card slot
Upward convex on 31 bottom surface to be equipped with plush copper 32, which is plugged in the butt hole 52, is fixedly installed at the top of the plush copper 32
Flexible gasket 33, the flexible gasket 33 are made of silica gel material, which has arcuation outer surface 34.
As shown in Fig. 2, the line position sliding block 30 is connected with link block 70, on the link block 70 when specific implementation
Inclination guide hole 71 is offered, inclination guide post 72 is equipped in the inclination guide hole 71.
When utility model works, when upper cores 10, lower mode 20 mold, bullet block 50 is promoted card slot by spring 60
Line position is blocked in 31, this moment, bullet block 50 can be made smoothly to be stuck in the plush copper 32 of card slot 31 by arcuation outer surface 34, simultaneously
Alleviate the pressing force of bullet block 50 by flexible gasket 33.
When die sinking, upper cores 10, lower mode 20 are initially separated, and bullet block 50 also starts disengaging line position slowly, due to card slot
31 be straight body slot, so bullet block 50 is also keeping off line position when upper cores 10, lower mode 20 separate, does not allow line position to be opened, works as upper mold
When benevolence 10, lower mode 20 are separated into preset distance, bullet block 50 has also completely disengaged card slot 31, and at this moment line position can safety open
Mould, and then have the function that line position delay die sinking.
