Description

A kind of screw element injection mold
Technical field
The utility model relates to a kind of screw element injection molds
Background technique
In moulding, numerous parts have screw thread, and screw thread demoulding is the key that such component die design.Rotating stripping demoulding It is common one of screw element stripping means.A multi-cavity mold can effectively improve the production efficiency of moulding, but for a mould The situation of multi-cavity, existing rotating stripping demoulding scheme have that demoulding stability is inadequate.
In addition, there are also a kind of demoulding spinning, i.e. forced stripper mechanism although forced stripper mechanism makes mould structure is opposite to obtain greatly Simplification, knockout course is also very efficiently convenient, but forced stripper mechanism can cause to damage to screw thread, and product disqualification rate increases, tool There is very strong limitation.
Utility model content
It is not high that the utility model solves the problems, such as to be limited to screw element injection mold demoulding stability.
A kind of screw element injection mold, including upper die and lower die and demoulding mechanism, upper mold include fixed clamping plate, solid plate, are determined Baffle plate two sides are fixed with the pull plate with sliding slot, and solid plate two sides are fixed with the slide bar for being placed in the sliding slot;The lower die Including moving template, moving clamping plate, moving template is fixed with core fixing plate and bearing plate, and core fixing plate is fixed with type core, type Forming gear is arranged with outside core, forming gear has outside screw type chamber, and forming gear, type core, moving template, solid plate collectively form Screw element injection molding chamber;The injection mold further includes demoulding mechanism, and demoulding mechanism includes ball screw and engaged therewith Ball nut, ball nut are fixedly connected with internal gear, and internal gear is engaged with forming gear;The ball screw wears out lower die Outer and lower end is fixedly connected via square slider with mandril, and bearing, ball spiral shell are respectively fixed on bearing plate and moving clamping plate Mother is arranged between above-mentioned two bearing, and ball screw can move up and down by the guidance of square slider.
On this basis, the injection molding chamber have at least two, internal gear respectively at least two injection molding chambers In at least two forming gears engagement.
On this basis, moving clamping plate is fixedly installed sliding sleeve, and in sliding in sliding sleeve, sliding sleeve lower end fastens square slider There is lower dead center of the stop nut as square slider.
The utility model is using ball lead screw drive mechanism driving forming gear rotation, high transmission accuracy;In using simultaneously Gear improves multiple screw elements demouldings when a multi-cavity mold forming thread part with the mode of multiple forming gear engaged transmissions simultaneously Stability and precision.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of screw element injection mold provided by the utility model
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those skilled in the art are obtained without making creative work The every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram of the screw element injection mold of the utility model.
A kind of screw element injection mold, including upper die and lower die and demoulding mechanism, upper mold include fixed clamping plate 17, solid plate 19, fixed clamping plate two sides are fixed with the pull plate 23 with sliding slot, and 19 two sides of solid plate are fixed with the slide bar for being placed in the sliding slot 14;The lower die includes moving template 20, moving clamping plate 5, and moving template 20 is fixed with core fixing plate 22 and bearing plate 24, type core Fixed plate 22 is fixed with type core 13 by key 11, and forming gear 12 is arranged with outside type core 13, and forming gear 12 has outside screw type Chamber, forming gear 12, type core 13, moving template 20, solid plate 19 collectively form screw element injection molding chamber;The injection mold is also Including demoulding mechanism, demoulding mechanism includes ball screw 6 and ball nut engaged therewith 8, and ball nut 8 and internal gear 10 are logical It crosses key 9 to be fixedly connected, internal gear 10 is engaged with forming gear 12;The ball screw 6 is worn out outside lower die and lower end is via side Shape sliding block 3 is fixedly connected with mandril 1, and bearing 25 and bearing 7, ball spiral shell are respectively fixed on bearing plate 24 and moving clamping plate 5 Mother 8 is arranged between above-mentioned two bearing, and ball screw 13 can move up and down by the guidance of square slider 3.Moving clamping plate 5 It is fixedly installed sliding sleeve 4, square slider 3 is slided in sliding sleeve 4, and 4 lower end of sliding sleeve is fastened with stop nut 2 as square slider 3 lower dead center, the interior key 21 for being equipped with guidance ball screw of moving template 20.
When work, the clamping mechanism of injection molding machine pushes moving template closely to compress upper mold with lower die, and then injection molding machine will expect The material of homogeneous heating plasticizing passes through charging barrel spray nozzle and sprue bush 18 and runner system injection type chamber in cylinder.Melt is cold in mould But after hardening, clamping mechanism unclamps, opening mold.
When die sinking, fixed clamping plate 17 is separated with solid plate 19 first, deviates from cast gate.When certain distance is arrived in die sinking, mold Two sides pull plate 23 is contacted with slide bar 14, separates solid plate 19 with moving template 20, the outside screw type chamber on forming gear 12 Under the action of screw thread resistance and core package clamp force, moulding is stayed on dynamic model, pull plate 23 breaks cast gate.At this moment mandril 1 connects Injection molding machine block is touched, ball screw 6 is moved axially, so that ball nut 8 and internal gear 10 be driven to rotate, the band again of internal gear 10 It moves multiple forming gears 12 to rotate, so that the outside screw type chamber on forming gear 12 be made to rotate;Due to type core 13 by key 11 with Core fixing plate 22 couples, so type core 13 is not rotated with type chamber external gear 12;The contact plane of type core 13 and moulding limits The rotation of moulding, therefore rotated by outside screw type chamber, the outside screw type chamber of moulding whiz forming gear 12 is forced, simultaneously Moulding is pushed to axially move demoulding.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and belong to this Shen Range please.
