Description
Technical field
The utility model relates to injection molds, more particularly to two shoulder locking positioning mechanism above and below injection mould slide block.
Background technique
In injection mold, if the side wall of plastic part is formed with side perforation structure, the ejecting mechanism in mold can not directly by
Plastic part ejection device, it is therefore desirable to side action sliders are set in the sidewall locations of the plastic part and with matching tiltedly led
Rod structure, in mold die sinking, after first passing through the structures such as the outside side core-pulling abjection side perforation of inclined guide pillar drive side action sliders, then
By ejecting mechanism by plastic part ejection device.For existing injection mold in mold-closing injection, it is fixed that side action sliders only rely on lower shoulder
The end face of plane and convex block and core side wall locking positioning only rely on lower shoulder positioning face contact, position inaccurate, unreliable, appearance
The end face stress for easily leading to convex block makes convex block extrusion pressing type core, uses the contact surface of the end face and type core that over time, lead to convex block
Abrasion, conquassation influence the service life of mold, or even influence plastics so that the plastic part surface of injection molding be made hair defect occur
Part molding.
Summary of the invention
The purpose of this utility model is to overcome prior art there are the shortcomings that, a kind of pair of side action sliders side is provided
Position up and down be divided into carry out locking positioning, it is accurate positioning, reliable, avoid stress between convex block and type core from squeezing, guarantee mold
Two shoulder locking positioning mechanisms above and below the injection mould slide block of service life.
The technical solution of two shoulder locking positioning mechanisms is above and below the utility model injection mould slide block: including upper compound plate under
Compound plate, setting type chamber under upper compound plate are arranged inclined guide pillar in type chamber, perforation are provided in lower compound plate, support block, support block is arranged on lower compound plate
Between lower compound plate on upper ejector retainner plate, lower ejector retainner plate and thimble are set, ejector pin passes through perforation and is in contact with lower ejector retainner plate,
Setting type core on support block is arranged side action sliders in core plate, oblique guide hole, oblique guide hole and inclined guide pillar phase is provided in side action sliders
Cooperation, is formed with convex block in the side of side action sliders, and lower shoulder positioning surface, the end face of convex block and the positioning of lower shoulder are formed with below convex block
Face is in contact with the side of type core, has the plastic part of injection molding between side action sliders, type core and type chamber, opens in plastic part
There is side opening, side opening is matched with convex block, type chamber locating piece is formed under the type chamber, it is fixed that the side of type chamber locating piece is formed with type chamber
Plane is formed with groove in side action sliders, and shoulder positioning surface, the type chamber of upper shoulder positioning surface and type chamber locating piece are formed in groove
Positioning surface is in contact.
The utility model discloses two shoulder locking positioning mechanisms above and below a kind of injection mould slide block, mainly make under type chamber
There is the type chamber locating piece of protrusion, there is type chamber positioning surface in the side of type chamber locating piece, groove is formed in side action sliders, in groove
Wall has upper shoulder positioning surface, when mold clamping, the type chamber positioning surface and the upper shoulder positioning surface phase of side action sliders of type chamber locating piece
Contact, while the lower shoulder positioning surface of side action sliders is in contact with core side wall, side action sliders in the case where molding locking state,
The position up and down (i.e. upper shoulder positioning surface and lower shoulder positioning surface) of side wall all obtains locking positioning, accurate positioning, reliable, to avoid
Side action sliders generate beat and stress between convex block and type core are caused to squeeze, and guarantee die life.
