Description
Technical field
The utility model relates to a kind of thruster pressure-bearing type bumper mold mould emptier, belongs to mould of plastics field.
Background technology
At present, adopt mould of plastics to produce bumper product, parting structure in generally all adopting, mould is at the inner bottom surface somatotype of bumper both sides, and parting line is positioned at inner bottom surface, makes the outer face, both sides of bumper smooth, attractive in appearance, and product specification is high.China Patent No. ZL201020268501.5, name is called " typing mechanism in automobile bumper mould " and discloses a kind of pushing block that arranges in slanted kicking block, pushing block is connected with pushing block guiding I-shaped plate by pushing block connecting rod, described pushing block guiding I-shaped plate is fixed on core fixing plate and main body core, in pushing block guiding I-shaped plate, be shaped with the guide runner of V-type, slide guide rail is installed in one end of pushing block connecting rod, and slide guide rail matches with guide runner.During die sinking, slanted kicking block is subject to the motive force effect of straight push rod still stay original position and depart from core fixing plate, and slide guide rail pulls slanted kicking block to move to right by pushing block connecting rod and pushing block in sliding process in V-type guide runner, slanted kicking block moves to right in process and drives goods glue gt to make goods glue position separated with main body die cavity, when sliding into turning point in V-type guide runner, realizes on slide guide rail the demoulding of goods glue position and main body die cavity, now main body die cavity die sinking is left, main body core continues to move downward, slide guide rail continues upward sliding in V-type guide runner, be subject to the effect pushing block connecting rod of V-type guide runner to promote the left cunning of pushing block, until goods glue position and the demoulding of main body core, finally by ejecting mechanism, eject goods pickup.Slide guide rail is all to connect pushing block connecting rod by pivot pin, and in real work, slide guide rail slides in V-type guide runner, be all by pivot pin, to be born the thrust of slip, while particularly arriving V-type corner, the pressure bearing is maximum, easily make pivot pin fracture, whole secondary mould is broken down, cause damage.On the other hand, ejecting mechanism adopts Double-ejection mode, common secondary ejecting mechanism is spacing interlock pushing method at present, mainly comprise drag hook resetting block and drag hook, and drag hook slide block and Compress Spring, drag hook is held drag hook and is slided, and under the effect of drag hook resetting block and Compress Spring, depart from drag hook slide block, existing drag hook slide block does not have guide mechanism, and drag hook slide block easily blocks (position) and lives compressing into and skid off process, causes the accident.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art; a kind of employing transmission pressure-bearing mode is provided; alleviate the thruster holding capacity of thruster roller (slide guide rail); avoid roller shaft pin to fracture; and ejecting drag hook slide block slides smooth; not screens, reduces mould fault rate, improves the thruster pressure-bearing type bumper mold mould emptier of mould production efficiency.
The technical scheme of the utility model thruster pressure-bearing type bumper mold mould emptier is: comprise stationary mould for mould fixed head and dynamic mould fixing plate, cover half die cavity is installed under cover half fixed head, two mould pin are installed on dynamic mould fixing plate, on mould pin, dynamic mould core is installed, the bumper that has injection mo(u)lding between dynamic mould core and cover half die cavity, between two mould pin, upper plate is set, lower roof plate and thimble, upper plate and lower roof plate are provided with Double-ejection spacing mechanism, straight jacking block is installed on lower roof plate, straight jacking block connects slanted kicking block through I-shaped, the outside of slanted kicking block is installed interior somatotype and is inserted, interior somatotype is inserted and is matched with interior minute back-off of bumper both sides, the inwall that interior somatotype is inserted connects push rod, push rod is through slanted kicking block, the inner portion of push rod connects roller through pivot pin, installation side pushing block in dynamic mould core, in thruster piece, be shaped with V-type thruster chute, roller matches with V-type thruster chute, it is characterized in that, in described thruster piece, pressure block is installed, described pressure block is positioned at the corner A place of V-type thruster chute, and corner A place and pressure block transmission, described push rod head end arranges slide guide cambered surface, slide guide cambered surface contacts with pressure block.
The utility model discloses a kind of thruster pressure-bearing type bumper mold mould emptier, after mould die sinking (dynamic mould core is separated with cover half die cavity), by injection machine power (fore-set), promote lower roof plate, lower roof plate drives on straight jacking block and pushes up, straight jacking block drives slanted kicking block upwards inwardly to eject, in slanted kicking block drives, somatotype is inserted by the roller on push rod along the inside thruster of V-type thruster chute, interior somatotype is inserted and forced to pour in separately to smash in bumper to pull out, now, there is distortion a little the both sides of bumper, when bumper is by after the demoulding of Double-ejection spacing mechanism, the ductility having by plastic material itself, it is normal that crushed element recovers, do not affect outward appearance and the intensity of bumper.In the process that somatotype is inserted in thruster, the pulling force of thruster is mainly born by the pivot pin of roller, when roller is rolled into the corner A place of V-type thruster chute, the thruster pulling force bearing is maximum, therefore, in the thruster piece at corner A place, pressure block is installed, and between corner A place and pressure block, doing open-work processes, head end at push rod arranges slide guide cambered surface, when roller slides into corner A place, by slide guide cambered surface, through transmission, contacted with pressure block, namely slide guide tip-cambered is on pressure block, keep out the thruster pulling force that interior somatotype is inserted, pivot pin is not stressed herein, alleviate pivot pin pressure, prevent pivot pin distortion, even fracture, avoid mould to break down, enhance productivity.
Thruster pressure-bearing type bumper mold mould emptier of the present utility model; described Double-ejection spacing mechanism comprises the spacing release link that is arranged on dynamic mould fixing plate one side; spacing release link connects upper plate; the sidewall of described upper plate is installed pull bar drag hook; the sidewall of lower roof plate is shaped with installation Compress Spring and guiding briquetting in recess recess; in guiding briquetting, drag hook slide block is set; pull bar drag hook matches with drag hook slide block; there is guiding briquetting; drag hook slide block stretches out or compresses into smoothly; not stuck, avoid mould to break down.Mounting guide sleeve between described push rod and slanted kicking block, makes push rod thruster smooth.
