Description
Technical field
The invention belongs to mold component technical field, the rotation of more particularly to a kind of circular arc refrigerator drawer handle die is slided
Block core-pulling mechanism.
Background technology
Injection moulding occupies highly important status in whole manufacturing production.According to estimates, injection molding product
Account for 1/3rd of all mold tool plastic product total outputs, injection mould account for 1/2nd of mould for plastics quantity with
On.Importance of the injection mold in mould industry is apparent.
In industrial processes, the mould emptier of back-off is most important one in injection molding process on injecting products
Link, it determines the complex degree of structure of injection mold and the size of die size, so as to determine the cost and product of mould
The production efficiency of product.
In recent years, in order to meet customer it is aesthetic the need for, the handle design of some refrigerator drawers is in the arc-shaped.Circular arc is fallen
Button is unable to the demoulding using traditional slide block structure.The rotary slider mechanism for using at present, big multiplex 2 oil cylinders, one of oil
Cylinder band carry-over bar, is rotated, the whole sliding block of another hydraulic oil cylinder driving by gear driven rotary slider.Or with an oil cylinder and tiltedly
Guide pillar, wherein Angle Pin drive tooth bar, are rotated by gear driven rotary slider, the whole slide block movement of hydraulic oil cylinder driving.Due to adopting
With rack-and-pinion and oil cylinder, mould structure complexity, greatly, die cost is high, low production efficiency for die size.Due to oil cylinder oil leak,
The problems such as also product being polluted.Accordingly, it is now desired to be solved the above problems using a kind of new scheme.
The content of the invention
The present invention is to solve the rotary slider mechanism that the circular arc back-off demoulding of the prior art is used, and mould structure is multiple
Miscellaneous, die size is big, and die cost is high, the problem of the technology of low production efficiency, there is provided a kind of circular arc refrigerator drawer is fingerprint
The rotary slider core-pulling mechanism of tool, is cooperated using curved pin and Angle Pin and drives whole sliding block and rotary slider, structure respectively
It is compact, die size, improve production efficiency can be effectively reduced.
To solve the above problems, technical scheme is as follows：
A kind of rotary slider core-pulling mechanism of circular arc refrigerator drawer handle die, including big sliding block, Angle Pin, curved pin and rotation
Slide block assembly；
There is perforate on big sliding block, can respectively supply curved pin, Angle Pin lower end to pass through；
Rotary slider component is screwed on big sliding block；
The rotary slider component includes fixed block, limited block, small slide block, the first shovel chicken, the second shovel chicken, rotary slider, axle；
The small slide block is connected with rotary slider by the second pin, the time delay for having 3-5mm；First shovel chicken, second shovel chicken with it is small
Sliding block is connected by the first pin, than small slide block time delay 3-5 mm；There is perforate on small slide block, it is relative with the perforate on big sliding block
Should, it is available for Angle Pin lower end to pass through；
The limited block crosses mode connects for screw on fixed block；
The rotary slider is connected by axle with big sliding block；
There is perforate on the fixed block, it is corresponding with the perforate on big sliding block, small slide block, it is available for Angle Pin lower end to pass through, it is described
Small slide block, the first shovel chicken, the second shovel chicken and rotary slider can be inserted into inside fixed block after assembling.
As a modification of the present invention, the rotary slider core-pulling mechanism of the circular arc refrigerator drawer handle die it is small
Pin hole on sliding block is mounting hole, can play a part of time delay.
As a modification of the present invention, the of the rotary slider core-pulling mechanism of the circular arc refrigerator drawer handle die
One shovel chicken, the pin hole of the second shovel chicken are mounting hole, can play a part of time delay.
Used as a modification of the present invention, the small slide block of the circular arc refrigerator drawer handle die has with rotary slider
The time delay of 3.5mm；The second shovel chicken is than the mm of small slide block time delay 5.
During mould use, after product injection terminates, when mould is opened, curved pin and Angle Pin are with solid plate one
Motion is played, at this moment the straight figure of curved pin withstands big sliding block, remains stationary as big sliding block, Angle Pin drives small slide block and the first shovel
Chicken, the second shovel chicken motion, when being connected by the second pin due to small slide block and rotary slider, there is the time delay of 3.5 mm, small slide block
With the first shovel chicken, after the second shovel chicken moves 3.5 mm together, this is that the first shovel chicken and the second shovel chicken have been moved off rotary slider, small
When sliding block is further continued for motion, sliding block is rotated by the second pin and is rotated around axle；When mould open 105 mm apart from when, it is small
Sliding block is rotated sliding block and rotates 30 degree of angles, rotary slider is completely disengaged from the circular arc back-off of drawer handle.
Mould is further continued for opening, and Angle Pin departs from small slide block, at this moment small slide block, and the first shovel chicken and the second shovel chicken reach spacing
The position of block, by the effect of limited block, makes small slide block, and the first shovel chicken and the second shovel chicken remain stationary as in big sliding block.When curved
After the straight figure of pin departs from big sliding block, the inclined-plane of curved pin drives big slide block movement, and at this moment rotary slider component is with big sliding block one
Motion is played, until whole big slide block assembly completely disengages from product.At this moment curved pin departs from big sliding block, and whole big slide block assembly stops not
It is dynamic；After mould is opened completely, injection machine ejecting product.
During matched moulds, pin curved first inserts big sliding block, drives big sliding block and rotary slider component to move together, when big sliding
After block resets completely, big sliding block stop motion.Matched moulds is further continued for, in the slanting guide pillar hole of Angle Pin insertion small slide block, continues to drive
Small slide block is moved, and small slide block shovels chicken by the first pin drive first and the second shovel chicken moves, and the first shovel chicken and second shovels chicken ratio
The mm of small slide block time delay 5；Small slide block is rotated sliding block and is rotated around axle by the second pin simultaneously, until mould is closed completely
Afterwards, the first shovel chicken and the second shovel chicken jam-packed rotary slider, make rotary slider be remained stationary as in injection.After mould is closed completely,
Producing for next cycle can be carried out.
Relative to prior art, advantages of the present invention is as follows, and the rotary slider of this circular arc refrigerator drawer handle die is taken out
Core mechanism overcomes conventional such mould and uses hydraulic oil cylinder driving slide block movement；Using oil cylinder, mould structure is complicated, die size
Greatly, die cost is high, low production efficiency, mutual using curved pin and Angle Pin the problems such as pollute product due to oil cylinder oil leak
Cooperation drives whole sliding block and rotary slider respectively, compact conformation of the present invention, can effectively reduce die size, reduce mould into
This, shortens the formed product cycle, significantly improves production efficiency.
