Its principle is as follows:Solid plastics particulate material enters from hopper receives heat in barrel, in the drive of servomotor Under dynamic, screw rod is rotated and moved axially simultaneously, and raw material plastifies and shift the melt plastified in the storage compartment of barrel front end onto, then Screw rod is moved and rotated further along, is promoted melt to be injected into from discharging joint in the die cavity of mould, is completed action of injection.This Squeezing structure in technical scheme is adapted to the raw material for being capable of Flashmelt, and solid plastics particulate material can be by after feeding cylinder is entered To comprehensive heating, quick plasticizing, a servomotor drives screw rod rotationally and axially to move simultaneously, efficiently quickly realizes molten The squeezing of material, production efficiency are high.
In the above-mentioned efficient squeezing set composite for injection machine, the end of the screw rod is connected by roller bearing On the connecting cylinder, the screw mandrel outer end has the chute along screw mandrel length direction, and the end of the screw rod has slip embedding The projection being located in the chute.So screw mandrel and screw rod realize be in axial sliding connection, circumferentially fixed connection, screw mandrel rotating When, connecting cylinder movement is driven, connecting cylinder can just drive screw rod to move axially, and at the same time, screw mandrel can also drive screw rod to turn It is dynamic.
In the above-mentioned efficient squeezing set composite for injection machine, have and the screw rod on the inwall of the barrel The thread groove that is engaged of screw thread, be additionally provided with control cabinet and the tracheae with being connected in the barrel in the frame.
In the above-mentioned efficient squeezing set composite for injection machine, the servomotor is coaxially disposed with the barrel And the servomotor is located at the upper end of the barrel, the hopper is located at the side of the servomotor, the hopper it is upper End is in opening, and lower end is in necking, and the upper end of the hopper is provided with screen pack.Solid plastics particulate material enters material from the hopper In cylinder, smooth efficient, screen pack can effectively avoid the entrance of foreign matter.
In the above-mentioned efficient squeezing set composite for injection machine, the discharging joint bending, which is retreaded, to be set up. So both facilitated the connection of the discharging joint and mould to install, and can also avoid also without the raw material melted under gravity It is directly entered die cavity or gum-injecting port.
Compared with prior art, solid plastics particulate material can after entering feeding cylinder under gravity in the utility model By comprehensive heating, quick plasticizing, then screw rod is driven rotationally and axially to move simultaneously by a servomotor, it is efficiently fast Speed realizes the squeezing of melt, production efficiency height.
