Upper ejector retainner plate, lower ejector retainner plate and thimble are set on plate, and ejector pin passes through perforation and is in contact with lower ejector retainner plate, is arranged on support block
Side action sliders are arranged on type core in type core, and setting drives the ejection limiting device of side action sliders side core-pulling, institute on type core
Mounting hole is provided in the type chamber stated, the upper end of mounting hole is formed with limit concave station, and inclined wedge, the side wall system of inclined wedge are arranged in mounting hole
There is oblique locking face, the upper end of inclined wedge is formed with limit plate, and limit plate is matched with limit concave station, is formed in the outer wall of side action sliders
Side locking face, side locking face are matched with the oblique locking face of inclined wedge.
The utility model discloses a kind of embedded retaining mechanisms of injection mould slide block spring core pulling inclined wedge, mainly by type
Chamber and inclined wedge separately manufacturing form, and by being provided with mounting hole in type chamber, the upper end of mounting hole is formed with limit concave station, in mounting hole
Middle setting inclined wedge, the upper end of inclined wedge are formed with limit plate, and inclined wedge is inserted into from the top of mounting hole, by the limit plate and limit of inclined wedge upper end
Position concave station cooperation, limits inclined wedge, then type chamber is fixed on upper compound plate through fastener, the top of inclined wedge is pushed down by upper compound plate
Portion fixes it.The embedded retaining mechanism of this programme injection mould slide block spring core pulling inclined wedge, type chamber system seperated with inclined wedge
Cause type, keep pocket machining simpler, conveniently, to save the processing cost of mold, and if inclined wedge it is long-term when after occur
Abrasion, can also individually split out replacement, reduce the maintenance cost in mold later period.
The embedded retaining mechanism of the utility model injection mould slide block spring core pulling inclined wedge, the ejection limiting device packet
Position-limitting pin is included, lower end and the type core of position-limitting pin are mutually fixed, and spring groove is provided in side action sliders, top is arranged in spring groove
The side of spring out, ejector spring is in contact with spring groove, and the other side of ejector spring is in contact with core side wall.When mold by
After being gradually opened, inclined wedge is disengaged with side action sliders, and ejector spring pushes out side core-pulling under the action of restoring force at this time
Sliding block makes the side perforation structure of side action sliders extraction plastic part side wall, when side action sliders are in contact with position-limitting pin, by
Position-limitting pin plays position-limiting action to side action sliders, limits it in the position, when making mold clamping, the oblique locking face of inclined wedge
With the side locking face of side action sliders, be conducive to that side action sliders is driven to reset, and the position limiting structure of position-limitting pin is simple, installation
It is convenient.
