Abstract
The present invention discloses a double plate injection molding machine movable template driving mechanism, which comprises a fixed template, a movable template, a motor, a lead screw and a lead screw nut, wherein the motor is fixedly arranged on the movable template, one end of the lead screw is fixedly connected with the fixed template, and the lead screw nut and the lead screw form a screw connection. The double plate injection molding machine movable template driving mechanism is characterized in that the lead screw nut and the rotation shaft of the motor form a positioned connection through a positioning pin, a pushing force bearing and a pressing sleeve are respectively sleeved on the lead screw nut, the pressing sleeve and the lead screw nut are sealedly connected and the pressing sleeve and the housing of the motor are fixed so as to press the lead screw nut to make the lead screw nut and the rotation shaft of the motor be fixed, and the pressing sleeve and the lead screw nut are respectively provided with radial lubrication holes. The double plate injection molding machine movable template driving mechanism of the present invention has the following advantages that: with the fixed connection between the lead screw nut and the rotation shaft of the motor, the connection safety and reliability is ensured, and the loose is not easily generated;; and the pressing sleeve and the lead screw nut are respectively provided with the radial lubrication holes, such that the lubricating oil can be injected between the lead screw and the lead screw nut so as to make the lead screw nut smoothly and flexibly rotate and increase the service life.
Description
Technical field
The present invention relates to injection machine, more particularly to a kind of drive mechanism of double-plate injection moulding machine moving platen.
Background technology
Moving platen in injection machine is generally driven using hydraulic pressure+linkage at present, but this type of drive is reacted not
It is enough sensitive, and fault rate is higher, has pollution to working environment, therefore, also having
It is dynamic.But current motor+leading screw type of drive, is typically with rotating shaft of the screw directly by feed screw nut with motor and fixes company
Connect, this causes motor operationally, screw is susceptible to release or even is cut off because directly shearing, cause to drive failure, this
Outward, cannot lubricate between leading screw and feed screw nut.
The content of the invention
It is firm with the attachment security of machine shaft that the technical problem to be solved is to provide a kind of feed screw nut
The drive mechanism of double-plate injection moulding machine moving platen.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for：A kind of driving machine of double-plate injection moulding machine moving platen
Structure, including fixed form, moving platen, motor, leading screw and feed screw nut, described motor are fixedly mounted on described moving platen
On, one end of described leading screw is fixedly connected with described fixed form, described feed screw nut and described leading screw bolt,
Rotating shaft of the described feed screw nut by multiple equally distributed alignment pins with described motor is located by connecting, described leading screw spiral shell
Be arranged with thrust bearing and clamping sleeve on mother respectively, described clamping sleeve be tightly connected with described feed screw nut and with it is described
The shell of motor is fixed, and is fixed for compressing the rotating shaft that described feed screw nut makes which with described motor, described clamping sleeve
With the lubrication hole that radial direction is respectively arranged with described feed screw nut, the lubrication hole on described feed screw nut is positioned at described pressure
The inside of tight set.
Positioning convex ring it has been wholely set in the rotating shaft of described motor, the rotating shaft of described motor is near described leading screw spiral shell
Two-direction thrust bearing is arranged with female one end, one end of described two-direction thrust bearing is withstood on described positioning convex ring, institute
Locking nut is bolted with the rotating shaft of the motor stated, described locking nut compresses described two-direction thrust bearing.
Leading screw connecting seat is fixedly installed on described fixed form, one end of described leading screw is connected with described leading screw
Seat is fixedly connected.
Compared with prior art, it is an advantage of the invention that the feed screw nut is ensure that with the mode that is fixedly connected of machine shaft
Attachment security reliability between the two, and be difficult to release, simultaneously because being respectively arranged with radially on clamping sleeve and feed screw nut
Lubrication hole, can be to lubricating oil be added between leading screw and feed screw nut so that the rotation of feed screw nut is smooth flexibly, while also carrying
High service life.
