Description

Injection mold directly pushes up and swings the back-off stripper apparatus of loosing core
Technical field
A kind of back-off that the present invention relates to injection mold stripper apparatus of loosing core, specifically refers to that injection mold will be for willBeing embedded in back-off pellet in the goods back-off structure demoulding a kind of injection mold out of loosing core directly pushes up and swings back-off and take outCore stripper apparatus.
Background technology
Injection mold is called back-off by being embedded in the demoulding behavior out of loosing core of back-off pellet in goods back-off structureLoose core, prior art adopts angle ejector rod carrying back-off pellet, by the oblique mode ejecting by back-off pellet fromIn the back-off structure of goods, loose core out, be called for short slant-top core-pulling, due to the oblique work that ejects of slant-top core-pulling deviceWork need to take larger mould inside space, causes body increase, the cost up of mould, therefore, existingThere is technology to have the problems and shortcomings that mould body is large, cost is high.
Summary of the invention
The problems and shortcomings that exist for above-mentioned prior art, the present invention adopts by swing arm, guide pad, straightThe device that push rod forms, swing arm is provided with gathering sill, and guide pad is provided with guide finger, and straight push rod is provided with rotating shaft;The back-off pellet of mould is fixedly located at the upper end of swing arm, and the lower end of swing arm is rotatably connected through described rotating shaftIn the upper end of straight push rod, described gathering sill and described guide finger sliding connection, when work, guide finger drawsLead swing arm and keep straight on and oscillating motion under the effect on the straight top of straight push rod, drive back-off pellet is from goodsThe technical scheme of loosing core out in back-off structure, provides a kind of injection mold directly to push up to swing loose core demoulding dress of back-offPut, be intended to directly push up swing to loose core and substitute oblique top and tiltedly move and loose core, the back-off of injection mold is loosed core and avoid obliqueThe drawback of loosing core in top, reaches the object that reduces mould body, reduces costs.
The object of the present invention is achieved like this: a kind of injection mold directly pushes up and swings the back-off stripper apparatus of loosing core,Comprise swing arm, guide pad, straight push rod, wherein: described swing arm is the steel components of rectangle column,Before and after swing arm cylinder is provided with, the bending strip through hole of penetrating above-below direction is called gathering sill, described gathering sillTop be craspedodrome section from top to bottom, the bottom of described gathering sill is the diagonal section being tilted to the right from top to bottom;Swing arm upper end is fixed with the back-off pellet of the back-off structure of moulded products; The lower end of swing arm be provided with forBe rotationally connected the tenon of the flat protrusion of straight push rod;
Described guide pad is block steel components, and the left part of guide pad is provided with to overlook and is the upper and lower of concave shapeThe groove of direction is called gathering sill, and described gathering sill center is provided with the steel cylinder that fore-and-aft direction runs through gathering sillShaft-like guide finger;
Described straight push rod is the steel components of rectangle column, and the upper end of straight push rod is provided with for being rotationally connected pendulumThe groove described tenon of lever, left and right directions is called tongue-and-groove; Described tongue-and-groove center is provided with fore-and-aft direction and passes throughWear the shaft-like rotating shaft of steel cylinder of tongue-and-groove;
Swing arm is rotatably connected in the upper end of straight push rod, the institute of guide pad through described tenon, tongue-and-groove and rotating shaftState gathering sill slip and clamping swing arm, guide pad slides through described gathering sill and swing through described guide fingerBar connects; When application, swing arm slides and is arranged in the placement hole of dynamic model support plate, described back-off pellet slip positionIn the resettlement groove of dynamic mould core, the straight lower end of push rod and the top board of mould are fixedly connected with, and guide pad is positioned at pendulumThe right side of lever is fixedly connected with dynamic model support plate, and guide finger is positioned at described gathering sill described in mould matched moulds tenseThe top of the described section of keeping straight on.
The direction face of said structure statement is divided into up, down, left, right, front, rear side, wherein, before be faceTo the face of device front view, after be with described before relative face.
Operation principle and beneficial effect
When application, mould is horizontal installation, the fore-and-aft direction that the above-below direction that structure is described is job description.
When work, mould die sinking, dynamic model is mobile and cover half somatotype backward, and transverse slider transverse shifting departs from systemProduct, top board drives goods push rod, straight push rod synchronously to move forward, and first, described guide finger slides described and leadsTo the described craspedodrome section of groove, now guide finger guiding swing arm and back-off pellet are synchronously straight forward with goods push rodRow pushing tow goods depart from dynamic mould core; Afterwards, guide finger slides the described diagonal section to gathering sill, guide fingerGuiding swing arm and back-off pellet swing from bottom to top centered by described rotating shaft, make back-off pellet from goodsIn back-off structure, loose core the demoulding out.
This apparatus structure is simple, tiltedly moves to realize back-off loose core by the alternative oblique top of straight top swing, takies in mouldPortion space is little, has therefore reduced mould body, has reduced die cost.
Above-mentioned, the present invention adopts the device being made up of swing arm, guide pad, straight push rod, and swing arm is provided with leadsTo groove, guide pad is provided with guide finger, and straight push rod is provided with rotating shaft; The back-off pellet of mould is fixedly located at swing armUpper end, the lower end of swing arm is rotatably connected in the upper end of straight push rod through described rotating shaft, described gathering sill withDescribed guide finger sliding connection, when work, guide finger guiding swing arm is in the effect on the straight top of straight push rodLower craspedodrome and oscillating motion, the technical scheme that drives back-off pellet to loose core out from the back-off structure of goods,Overcome prior art and had the problems and shortcomings that mould body is large, cost is high, a kind of injection mould providingTool directly pushes up and swings the back-off stripper apparatus of loosing core, and substitutes oblique top and tiltedly moves directly to push up to swing, and injection mold is reachedThe object that reduces body, reduces costs.
