The ejection cylinder adopts layer nesting structure, comprising a rear cover with an embossed cross-section. The cylinder jacket sheathed on the rear cover and the plunger between the back cover and the cylinder jacket is provided with a hole in the axial direction of the back cover and a hole in the center of the plunger. The transmission is sheathed in the hole of the back cover. The transmission shaft passes through the hole of the plunger. For the ejection screw rod and the ejection cylinder are positioned on the same axis, the utility model has the advantages of stable injection force, compact structure, easy production, and reliable guiding.
Description
(1) technical field
The utility model relates to a kind of injection machine injection mechanism.
(2) background technology
Existing injection machine injection mechanism injection force instability is easy to generate asynchrony phenomenon, and movement inertia is big, is difficult to guarantee the precision of injection position.
(3) utility model content
The purpose of this utility model provides the injection machine injection mechanism that a kind of injection force is stable, the injection position precision is high.
In order to achieve the above object, oil motor, the injection oil cylinder that the utility model is achieved in that the nozzle that comprises rubber melting cylinder, be located at the rubber melting cylinder front end, is located at the screw rod in the rubber melting cylinder, the power transmission shaft that is connected with screw rod, the drive sleeve that is connected with power transmission shaft, driving drive sleeve rotate, penetrate and move oil cylinder, penetrate and move guide rod, be located at and penetrate the injection header board that is used for fixing rubber melting cylinder that moves on the guide rod, be located at and penetrate after the injection that is used for fixing oil motor of moving on the guide rod plate and reach fixedly to penetrate and move penetrating of guide rod and move support; It is characterized in that: the injection oil cylinder is the layered set type structure, and it comprises that section is the bonnet of convex shape, be set in the oil cylinder cover on the bonnet and be located at the piston of bonnet between overlapping with oil cylinder, bonnet axially have a hole, also have the hole at the center of piston; Drive sleeve is located in the hole of bonnet, and power transmission shaft passes the hole of piston.
Of the present utility modelly further be improved to, between drive sleeve and bonnet, be provided with two radial bearings.Between power transmission shaft and piston, be provided with conical bearing and thrust bearing.Be provided with four pull bars after injection header board and the injection between the plate.Penetrate the base that moves oil cylinder and be fixed on after the injection on the plate, its piston brace rod with penetrate that to move support hinged.
The utility model advantage compared with prior art is, injecting screw and injection oil cylinder are on an axis, and injection force is stable, avoided twin-tub (in the screw rod both sides) injection to be easy to generate asynchrony phenomenon; During injection, have only screw rod, piston and power transmission shaft motion, the weight of movement parts reduces to the lightest, so movement inertia is minimum, like this, the injection position precision is guaranteed easily.And, because an injection piston axially reciprocating, do not rotate, help sealing durable with seal; Penetrate and move oil cylinder and place in the forward and backward support, the tuberculosis compactness is saved the space; Dijection moves guide rod structure, makes simply, and guiding is reliable.
