Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, and a kind of secondary demoulding is provided, and guarantees the mould emptier of bottle cap extrusion molding mold pressing bottle capper complete, that deviate from from mould fast.
The technical scheme of the mould emptier of the utility model extrusion molding mold pressing bottle capper is: comprise frame; in frame main shaft is installed; install fixed head at main shaft; cope match-plate pattern and lower bolster; patrix is installed in upper mounted plate, and patrix passes cope match-plate pattern, and counterdie is installed in the lower bolster; upper die and lower die match; described patrix comprises core rod, and core rod fixes through upper fixed cover and upper mounted plate, is equipped with the core rod cover under core rod; the outer stripper sleeve that is equipped with of core rod cover; in the core rod cover core rod cover is arranged, in the core rod cover core rod is installed, described counterdie comprises lower tringle; on the lower tringle lower die head is installed; it is characterized in that in the fixed plate charging ram being installed, roller is installed on the charging ram, the guide rail of cam-type is installed at upper rack; guide rail contacts with roller; the charging ram outer wall is installed back-moving spring, and back-moving spring contacts with cope match-plate pattern, and contiguous block is installed in the charging ram bottom; contiguous block and stripper sleeve outer wall fix; open pore on the wall of described stripper sleeve, pore connects air nozzle, passes into compressed air in the air nozzle.
The utility model discloses a kind of mould emptier of extrusion molding mold pressing bottle capper, when upper, when the lower bolster driven mold rotates to die sinking position, by counterdie to lower open die, the die sinking rear roller contacts with the guide rail of cam-type, roller rolls downwards along the inclined-plane of guide rail, simultaneously roller drive charging ram vertically moves downwards, charging ram drives stripper sleeve through contiguous block and vertically moves downwards, when roller moves to the tip position of guide rail, charging ram drives stripper sleeve and downwards bottle cap part from core rod is deviate from, because stripper sleeve moves down, and core rod, core rod cover and core rod cover maintain static, so the pore of stripper sleeve inwall exposes, be blown into compressed air the pore from air nozzle this moment, be blown into the stripper sleeve inner chamber from pore again, bottle cap is blown out, finish the demoulding; Then upper and lower template continuation driven mold moves, after roller had been crossed the tip position of guide rail, charging ram was under the effect of back-moving spring restoring force, and roller is along guide rail uniform roll obliquely, charging ram drives stripper sleeve and at the uniform velocity moves up, and makes the stripper sleeve homing.The mould emptier of this programme extrusion molding mold pressing bottle capper; adopt the mode of the secondary demoulding; elder generation contacts the drive charging ram with guide rail by roller and stripper sleeve is deviate from bottle cap downwards; be blown into air pressure in the pore of stripper sleeve from air nozzle again; bottle cap is carried out the secondary demoulding; the assurance bottle cap is deviate from fully; stripping rate is fast; and the guide rail of cam-type (as crossing the mountain peak form), after deviating from mould at bottle cap, roller can at the uniform velocity upwards drive the stripper sleeve homing along guide rail; with respect to prior art after bottle cap is deviate from; guide rail disconnects, and stripper sleeve is rapidly upwards resilience under the effect of back-moving spring, affects the service life of stripper sleeve.
The mould emptier of the utility model extrusion molding mold pressing bottle capper is installed cooling water pipeline in the described core rod.Cooling water pipeline has been arranged, upper mold cavity has been cooled off, guaranteed its service life.
