Abstract
The invention declares a core-pulling and demoulding combination device, which comprises a fixed template and a movable template forming a cavity, wherein a slide block, an inclined guide post, a lateral mold core, a positioning mechanism and an ejector rod are arranged in the cavity; the lateral mold core is hinged to the slide block; the ejector rod and the inclined guide post are fixed in the cavity; the positioning mechanism comprises a compression spring and a bolt; the inclined guide post is fixed on the fixed template; the lateral mold core is hinged to the slide block through a pin; during mold opening, the fixed template move upwards, the inclined guide post drives the slide block to move to the left in a guide sliding chute in the movable template, so as to complete the core-pulling action; in order to guarantee that during mold closing, the inclined guide post can accurately enter into an inclined hole in the slide block to facilitate reset of the slide block, a positioning device is arranged on the mechanism; and with the bolt and the compression spring, the slide block is propped against a spacing stop block for positioning when withdrawn. During the whole process, the demoulding and core-pulling are good in processing property, the cost is low, and therefore, the device provided by the invention is suitable for medium and small sized injection moulded pieces.
Description
Technical field
The present invention relates to the shaping mould field, demoulding integrated device specifically refers to loose core.
Background technology
The demoulding is last link in the injection mo(u)lding circulation; though the cold solid moulding of injection-molded item, the demoulding still has very significant effects to Products Quality, and stripping means is improper; may cause product unbalance stress when the demoulding, cause defectives such as product distortion when ejecting.
After the injection moulding, plastic is cooling and shaping in mould, and when having apertura lateralis or medial and lateral on the plastic when recessed, plastic can not directly be deviate from from mould.Must extract the side direction core out before the plastic demoulding, and then from mould, release plastic.Because the contraction of plastic volume, the side direction core produced hold power tightly, the power of loosing core that detent mechanism is required must overcome the resistance of loosing core because package power is caused, could pull out the side direction core.
Summary of the invention
The present invention is by the setting demoulding integrated device of loosing core, and the side direction core is difficult to problems such as extraction when solving the demoulding, reaches the purpose of the efficient demoulding.
Purpose of the present invention reaches by the following technical programs:
The present invention's demoulding integrated device of loosing core, comprise solid plate, moving platen, described solid plate and moving platen constitute die cavity, are provided with slide block, Angle Pin, side direction core and push rod in the described die cavity, described side direction core and slide block are hinged, and push rod and Angle Pin are fixed in the die cavity.Angle Pin is fixed on the solid plate, and the side direction core is hinged by pin and slide block, and during die sinking, cover half is pulled to move and made Angle Pin force slide block to be moved to the left in the guide runner of moving platen, finishes the action of loosing core; Angle Pin can enter in the inclined hole of slide block exactly when guaranteeing matched moulds, in order to slide block is resetted, mechanism is provided with positioner, abuts against on the positive stop after relying on screw and holddown spring that slide block is withdrawed from and locatees.In the whole process, the processing performance that the demoulding is loosed core is good, and cost is lower, is applicable to multiple middle-size and small-size moulding.
Further, also comprise the spring that is arranged on the push rod bottom, described spring is scroll spring.Adopt scroll spring, can provide stronger power for the rotation of push rod, make it to finish fast the action of loosing core, improve the production efficiency of injection mold; When the injection machine matched moulds, solid plate moves down and acts on push rod, makes it to be subjected to an impulsive force simultaneously, and Device element has been protected in the impulsive force that produces being cushioned of spring better, has improved the service life of equipment.
Further, as preferably, the angle of inclination of described Angle Pin is 20 °.Angle of inclination too conference increases space layout in the mould; The distance that the too little meeting in angle of inclination causes slide block to move diminishes, and does not reach the effect of the complete demoulding.So rational space layout at 20 °, had both been satisfied in the angle of inclination, can reach good stripping result again.
Further, also comprise detent mechanism and postive stop baffle, described detent mechanism comprises holddown spring and screw, and screw passes described postive stop baffle, and links to each other with slide block, and an end of holddown spring links to each other with postive stop baffle, and screw links to each other with the other end of holddown spring.During die sinking, when slide block is moved to the left, drives screw and be moved to the left, holddown spring is stretched; When matched moulds, spring is replied, and promotes slide block and resets.The setting of postive stop baffle is limited in the displacement of side direction core in certain scope, avoids the excessive stretching of spring and causes fracture.
Further, as preferably, the distance of loosing core is less than 80 ㎜.The distance of loosing core is oversize, makes mould specification increase thereby can make holddown spring or side direction core length increase; The distance of loosing core is too short, can make the side direction core not extract out fully from plastic.Be limited to injection machine internal structure layout, the distance limit of loosing core can guarantee normally carrying out of each parts in the detent mechanism below 80 ㎜.
Further, also comprise clamp, described clamp is arranged on the solid plate.The side direction core will be subjected to the effect of briquetting pressure during moulding, thereby make slide block be subjected to side force, thus also be provided with clamp in the mechanism, to keep the shaping position of slide block.
The present invention compared with prior art, have following advantage and a beneficial effect:
1 the present invention, comprise solid plate, moving platen, described solid plate and moving platen constitute die cavity, be provided with slide block, Angle Pin, side direction core, detent mechanism and push rod in the described die cavity, described side direction core and slide block are hinged, push rod and Angle Pin are fixed in the die cavity, and described detent mechanism comprises holddown spring and screw.In the whole process, the processing performance that the demoulding is loosed core is good, and cost is lower, is applicable to multiple middle-size and small-size moulding.
The angle of inclination of 2 Angle Pins of the present invention is 20 °, and angle of inclination too conference increases space layout in the mould; The distance that the too little meeting in angle of inclination causes slide block to move diminishes, and does not reach the effect of the complete demoulding.So rational space layout at 20 °, had both been satisfied in the angle of inclination, can reach good stripping result again.
