Abstract
The invention relates to an improved ejection pressure keeper of injection machine. Wherein, it comprises material cylinder, feeding screw, ejector, pressure keeper, and screw driver; the feeding screw via said screw driver rotates inside the material cylinder; the outlet of material cylinder is connected to one material guider which has bended material guide hole; the end of guider is connected to one material ejector with ejection through hole; the ejector at the end of through hole is fixed with pressure keeping cylinder whose piston rod is inserted into the end of through hole; the ejector at the front of through hole is fixed with ejecting open; the ejector also is connected to the material feeding hole connecting the ejecting open and guide hole. The invention can feed material when keeping pressure, switching mould and lifting out mould, to improve working efficiency.
Description
Technical field
The present invention relates to the injection machine technical field, specifically is to improve injection pressure-holding apparatus structure of injection machine.
Background technology
The principle of the common injection machine in market is to melting the pulpous state attitude with solid shape plastics (pellet or powder) heating plasticizing, inject the mold cavity of closed and locking with the vasopressing injection mode, take out through the pressurize cooling forming, become the process equipment of definite shape plastic products, injection machine mechanism is by comprising barrel, feed worm, nozzle shoots material, pressurize oil cylinder and spiro driving device, feed worm rotates in described barrel by described spiro driving device, weak point: above-mentioned structure pressurize unblank mould when ejecting feed process can not implement simultaneously, preface shoots material successively, pressurize, charging, die sinking, eject, locked mode carries out, take whole 1/3rd times of operation, reduce operating efficiency greatly.
Summary of the invention
The objective of the invention is to solve above-mentioned shortcoming, and provide a kind of charging, the pressurize mould of unblanking to eject the improvement injection pressure-holding apparatus structure of injection machine of implementing simultaneously.
For achieving the above object: comprise barrel, feed worm, nozzle shoots material, pressurize oil cylinder and spiro driving device, feed worm rotates in described barrel by described spiro driving device, the affixed material guiding parts of the discharge port end of its barrel, have the material guide hole that is bending in the material guiding parts, the material guiding parts end of material guide hole discharging opening also connects a material launching parts, have the through hole that shoots material on the material launching parts, shoot material and be fixed with the pressurize oil cylinder on the material launching parts of through hole tail end, piston rod sleeve incident material through hole tail end on the pressurize oil cylinder, shooting material is fixed with the nozzle that shoots material on the material launching parts of through hole front end, also is provided with the feedhole that is communicated with nozzle hole and material guide hole discharging opening on the described material launching parts.
Described feed member is an injection mouth flange, has the material guide hole that is " " shape in the injection mouth flange.
Described material launching parts is the injection flange, has the horizontal material shooting hole and the vertical feedhole that are " " shape in the injection flange.
Described spiro driving device is made up of motor and gearbox, and gearbox is driven by electric machine main shaft, and the output of gearbox connects feed worm.
Beneficial effect of the present invention: this structure adopts the affixed material guiding parts of discharge port end and the material launching parts of barrel, can realize pressurize, die sinking, charging simultaneously when ejecting with locked mode, whole working cycles than common injection machine saved for 1/3rd times, increased work efficiency greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in the figure, comprise barrel 1, feed worm 2, nozzle 3 shoots material, pressurize oil cylinder 4 and spiro driving device 5, feed worm 2 rotates in described barrel 1 by described spiro driving device 5, the affixed material guiding parts 7 of discharging opening 6 ends of its barrel 1, have the material guide hole 8 that is bending in the material guiding parts 7, material guiding parts 7 ends of material guide hole 8 discharging openings 6 also connect a material launching parts 9, have the through hole 10 that shoots material on the material launching parts 9, shoot material and be fixed with pressurize oil cylinder 4 on the material launching parts 9 of through hole 10 tail ends, piston rod 11 sleeve incident material through hole 10 tail ends on the pressurize oil cylinder 4, shoot material and be fixed with the nozzle 3 that shoots material on the material launching parts 9 of through hole 10 front ends, also be provided with the feedhole 16 that is communicated with nozzle hole 12 and material guide hole 8 discharging openings 6 on the described material launching parts 9, material guiding parts 7 is injection mouth flanges, have the material guide hole 8 that is " " shape in the injection mouth flange, material launching parts 9 is injection flanges, have the level that is " " shape shoot material through hole 10 and vertical feedhole 16 in the injection flange, spiro driving device 5 is made up of motor 13 and gearbox 14, gearbox 14 is driven by motor 13 main shafts 15, and the output of gearbox 14 connects feed worm 2.
Shot material the material after, pressurize oil cylinder 4 is closed vertical feedhole 16 during pressurize, simultaneously, feed worm 2 outlets are shut, but charging next time and pressurize die sinking, eject locked mode, after feed process puts in place, pressurize oil cylinder 4 piston rods 11 retreat to the end, and the through hole 10 that shoots material is unimpeded, next time, shoot material and to begin, realized pressurize, die sinking, ejected with four operations such as locked mode and charging and carry out simultaneously, saved product shaping cycle time greatly, improved shooting material successively stage by stage in the past, pressurize, charging, die sinking, eject the forming process with locked mode.
