Description
Technical field
Injection mold is the utility model is related to, more particularly to the secondary core-pulling of the cellular side riser of injection mold band
Structure.
Background technology
In injection mold, if the side wall of working of plastics is formed with riser, and gathered on the outer wall of riser honeycomb groove, circular groove, side
The structures such as groove, because more groove can be larger to the package powers of side action sliders, directly enter according to side action sliders from side
Row core pulling, then side action sliders can be caused to drive riser to move together, make to break between riser and working of plastics main body, molded product
Scrap, in order to overcome the defect, prior art is to be formed with upwardly-extending baffle in the fixed plate of side oil pumping cylinder, in side core-pulling
The rear side of sliding block sets side ejector retainner plate, and side thimble is set on the ejector retainner plate of side, and side thimble passes through the part of side action sliders and product
Honeycomb groove coordinates, and has certain gap between side ejector retainner plate and side action sliders, spring is set between side ejector retainner plate and baffle plate, when
When mould molds, side action sliders are driven to move outward by side oil pumping cylinder, but kept by spring thimble side ejector retainner plate, side thimble
Motionless, the riser that side thimble withstands working of plastics remains stationary as, and side action sliders is first deviate from the honeycomb groove of riser, and the structure is present
The shortcomings that be：Spacing between side ejector retainner plate and baffle plate is larger, and the elastic force of spring is not enough to support pin plate, easily causes to be molded
When, injection pressure is excessive, and is moved to the outside side action sliders, die cavity is changed, and mould molds, and side core-pulling is slided
Block can drive ejector retainner plate to move together when moving outward, so as to cause product rejection, and need to increase the thickness of side action sliders
Degree, so as to shorten the spacing between side ejector retainner plate and baffle plate, so result in side thimble length increase so that side thimble it is strong
Degree weakens, and is easily deformed or even is broken.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art to exist, there is provided a kind of offside ejector retainner plate support can
Lean on, shorten the length of side thimble, improve the intensity of side thimble, side action sliders is smoothly deviate from the riser of product, ensure production
The secondary core-pulling mechanism of the cellular side riser of injection mold band of quality.
The technical scheme of the secondary core-pulling mechanism of the cellular side riser of the utility model injection mold band is：Including upper multiple
Plate and lower compound plate, backing plate is set under upper compound plate, die cavity is set under backing plate, support block is set on lower compound plate, it is lower multiple between support block
Upper ejector retainner plate, lower ejector retainner plate and thimble are set on plate, core is set on support block, core insert is set in core, set on core
Side action sliders, side thimble is set, the outside of side action sliders sets side ejector retainner plate, and side ejector retainner plate is taken out with side in side action sliders
There is gap between core sliding block, side thimble connecting side ejector retainner plate, have between core insert, side action sliders, side thimble and die cavity
The working of plastics of injection molding, the both sides of working of plastics are formed with riser, honeycomb groove are formed with the outer wall of riser, it is characterised in that：It is described
Side ejector retainner plate outer wall Ejector Retainer Plate is set, spring is set in Ejector Retainer Plate, the side of spring is in contact with Ejector Retainer Plate, spring
Opposite side be in contact through side ejector retainner plate with side action sliders, be formed with projection in the side outer wall of Ejector Retainer Plate, projection it is outer
Wall is in contact with die cavity inwall, and Angle Pin is set in die cavity, and oblique guide hole, Angle Pin and oblique guide hole phase are provided with side action sliders
Coordinate, oil cylinder is set in the outer wall of core, the piston rod of oil cylinder is connected with side action sliders.
The utility model discloses a kind of secondary core-pulling mechanism of the cellular side riser of injection mold band, when working of plastics is noted
After being moulded into type, mould die sinking, now first with Angle Pin and the oblique guide hole of side action sliders, side action sliders are driven to move outward
Dynamic a small distance, and now the projection of Ejector Retainer Plate outer wall still contacts with the holding of facing directly of die cavity inwall, therefore die cavity top
Firmly Ejector Retainer Plate and side ejector retainner plate remain stationary as, and Ejector Retainer Plate and side ejector retainner plate drive side thimble to remain stationary as, and side thimble is withstood
The riser of working of plastics remains stationary as, make side action sliders gradually move outward abjection riser honeycomb groove, when side action sliders with
When side ejector retainner plate is in contact, now die cavity also moves up, and is disengaged with the projection of Ejector Retainer Plate, and die cavity can not be to thimble
Bottom plate carry out it is spacing, now oil cylinder through piston rod drive side action sliders move outward, side action sliders drive side ejector retainner plate and
Ejector Retainer Plate moves outward, and side ejector retainner plate and Ejector Retainer Plate drive side thimble to move the riser of abjection working of plastics outward, due to only
There is the cooperation of the honeycomb groove of several side thimbles and riser, therefore during the honeycomb groove of side thimble abjection riser, riser will not be driven together
Riser is broken in movement, so as to ensure its smooth core pulling.The secondary core-pulling of the cellular side riser of this programme injection mold band
Structure, first, the lateral wall in side action sliders sets side ejector retainner plate and Ejector Retainer Plate, side is set on side ejector retainner plate and Ejector Retainer Plate
Thimble, spring is set between Ejector Retainer Plate and side action sliders, so shortens the length of side thimble and spring, ensures side thimble
Structural strength and service life, and make spring there are enough spring energies to support side action sliders, prevent injection pressure excessive and
Deform die cavity；Second, the outer wall of Ejector Retainer Plate is formed with projection, to face directly, the inwall of facing directly of itself and die cavity connects the outer wall of projection
Touch, it is spacing to Ejector Retainer Plate using die cavity during die sinking, Ejector Retainer Plate, side ejector retainner plate, side thimble are supported reliable, side thimble is to perpendicular
Plate support is reliable, so as to prevent side action sliders from carrying out driving riser mobile when side is taken out or break riser, ensures product quality.
The secondary core-pulling mechanism of the cellular side riser of the utility model injection mold band, projection is formed with described projection
Inclined-plane, die cavity inwall are formed with die cavity inclined-plane, and during mould matched moulds, projection inclined-plane is engaged with die cavity inclined-plane.When mould matched moulds, by
Have spring between Ejector Retainer Plate and side action sliders so that Ejector Retainer Plate can not reset completely, have projection inclined-plane with
Die cavity inclined-plane coordinates, can be complete by being moved inward during die cavity matched moulds by die cavity inclined-plane through projection slope driving Ejector Retainer Plate
All reset, so as to avoid die cavity from being collided with Ejector Retainer Plate.
