Description
Technical field
The present invention relates to pulling mechanism in a kind of rosette mould secondary die sinking slide block, belong to injection mold field.
Background technology
During circuit arrangement, need to use rosette, the essential structure of existing rosette includes box body, box body is made
There is pre-manufactured hole, in the inwall of box body, be formed with binding post, binding post is formed with wiring hole, during production, first by rosette integral molded plastic
Molding, then rosette is put in punch press again, goes out pre-manufactured hole impression and wiring fixing hole, and its shortcoming is that rosette needs two
Secondary processing, time-consuming, low production efficiency.And binding post reaches box mouth from cassette bottom, and not only materials are many, and sometimes hinder pre-
Drilling threading, causes rosette using inconvenience.Therefore, the present inventor devises a kind of patch panel that arranges in inboard wall of cartridge and replaces
Binding post, patch panel small volume, materials save, and particularly do not interfere with pre-manufactured hole, do not affect threading.But, when mould is processed,
Because patch panel extends transversely in box body, between the bottom of patch panel and box body, form narrow and small back-off, wiring hole needs core again
Sub- core pulling, traditional moulds cannot machine-shaping.
Content of the invention
The invention aims to overcoming the shortcoming of prior art, a kind of mould secondary that is beneficial to is provided to mold power, band
Take out the demoulding in movable slider, mould inside slider designs are compact, inside take out having stable behavior, the rosette mould secondary die sinking of efficiency high is slided
Pulling mechanism in block.
The technical scheme that rosette mould secondary of the present invention molds pulling mechanism in slide block is: includes stationary mould for mould compound plate and moves
Mould compound plate, installs solid plate under cover half compound plate, installs fixed die insert in solid plate, and dynamic model compound plate is installed two pieces of support blocks, two moulds
On foot, dynamic mould fixing plate is installed, dynamic mould fixing plate arranges moving platen, moving platen installs moving die insert, the both sides of moving platen set
Put the combination of pre-manufactured hole core-pulling slide block, the gap between the combination of pre-manufactured hole core-pulling slide block and moving die insert and fixed die insert forms mould
, there is the rosette of injection mo(u)lding in chamber, is formed with patch panel and wiring hole in the inwall of rosette, set between two pieces of support blocks in die cavity
Put upper plate and lower roof plate, upper plate connects thimble, described moving platen has twice-die-opening mechanism it is characterised in that described
In dynamic mould fixing plate install in take out guide pad, inside take out guide pad both sides be formed with take out gathering sill, inside take out gathering sill connect in take out
Slide block, is formed with open slot in moving die insert, inside take out guide pad and interior slide block of taking out stretches in open slot, inside take out be formed with slide block recessed
Groove, moving die insert is formed with projection, and projection is formed with fuse, and projection and fuse embed and constitute patch panel and wiring casement in groove
Chamber.
Pulling mechanism in the rosette mould secondary die sinking slide block of the present invention, during the demoulding, injection machine power driven mold dynamic model
Partly downwards run die sinking, but moving platen is motionless under the effect of twice-die-opening mechanism, the cover half staying mould is partly gone up, that is, first
Secondary die sinking, dynamic mould fixing plate runs downwards, and it is descending to take out guide pad in drive, and interior take out gathering sill in the presence of, take out in drive
Slide block in open slot to contract, that is, interior take out, make in take out slide block from the inner side of patch panel extract out.Then, in twice-die-opening machine
Under structure effect, mould molds for second, and moving platen separates die sinking with solid plate, and moving platen drives dynamic model under die sinking dynamic action
Insert and interior slide block of taking out run downwards, and rosette follows moving die insert to run, until die sinking terminates, meanwhile, pre-manufactured hole is taken out
Core slide block combines also core pulling under twice-die-opening dynamic action, extracts out from the two side walls of rosette, makes the pre-manufactured hole impression demoulding.
Then, the push rod on injection machine promotes lower roof plate and upper plate, and upper plate drives thimble by rosette jack-up, makes the core on projection
Son ejects from wiring hole, then thimble continues jack-up, and by outside rosette ejection die, the demoulding completes.This programme adopts mould two
Secondary die sinking mode, takes out slide block and inside contracts the demoulding in drive, realize patch panel and wiring hole and be processed and formed at one time with rosette, in mould
Portion's compact conformation, core pulling having stable behavior, reliability, production efficiency is high.
Pulling mechanism in the rosette mould secondary die sinking slide block of the present invention, described pre-manufactured hole core-pulling slide block combination includes
On moving platen, slide guide insert is installed, slide guide insert arranges pre-manufactured hole core-pulling slide block, the head of pre-manufactured hole core-pulling slide block and dynamic model
Insert matches and constitutes pre-manufactured hole impression, and the afterbody of pre-manufactured hole core-pulling slide block is formed with inclined guide groove, installs oblique guide block, tiltedly in solid plate
Guide block is matched with inclined guide groove.When second molds, moving platen is run downwards and is separated with solid plate, pre-manufactured hole core-pulling slide block with
Descending, in the presence of oblique guide block and inclined guide groove, drive the outside core pulling of pre-manufactured hole core-pulling slide block simultaneously, pre-manufactured hole impression is taken off
Go out.Described twice-die-opening mechanism includes installing compression block tongue on the side wall of moving platen, and the side wall of solid plate is installed spacing
Drag hook, the side wall of dynamic mould fixing plate is installed spacing briquetting, and spacing drag hook holds compression block tongue, spacing briquetting and compression block tongue
Ramp matches.When molding for the first time, spacing drag hook holds compression block tongue, thus it is motionless to haul moving platen.When die sinking to
After set a distance, spacing briquetting press against the ramp of compression block tongue, so that compression block tongue is inside contracted, and departs from spacing drag hook, moving platen with fixed
Template separates, and realizes second and molds.
