Background technology
Adopt mould of plastics to produce threaded fitting; The prior art threaded fitting is when the demoulding, owing to receive the restriction of screw thread fuse, installation push rod under pipe fitting again; The main hydraulic motor that relies on is through gear driven screw thread fuse rotating stripping demoulding; By the workman threaded fitting is taken out, can not realize automatic demoulding, production efficiency is low.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, a kind of rotation push rod of in the screw thread fuse, installing is provided, make the automatic ejecting mechanism of plastic whorl pipe fitting rotation push rod of threaded fitting automatic demoulding.
The technical scheme of the rotational automatic ejecting mechanism of plastic whorl pipe fitting push rod of the present invention is: comprise upper mould plate and lower bolster, cope match-plate pattern connects solid plate down, and the mould pin is installed on the lower bolster; Between the mould pin top board is set, dynamic model backing plate and moving platen are installed on the mould pin, the threaded fitting of moulding is arranged between moving platen and the solid plate; The screw thread fuse is installed in the dynamic model backing plate, and the head of screw thread fuse matches with the screw thread inwall of threaded fitting, and the afterbody of screw thread fuse passes top board and is connected lower bolster through clutch shaft bearing with pressing plate; The screw thread fuse is equipped with gear wheel outward, between moving platen backing plate and mould pin, through second bearing driving shaft is installed, and driving shaft is by the power driven rotary; Driving shaft is installed pinion outward; Gear is meshed with gear wheel, it is characterized in that in the described screw thread fuse push rod being installed, and the top of push rod contacts with threaded fitting; The screw thread fuse is passed in the bottom of push rod, and contacts with the top board of the state of ejecting.
The rotational automatic ejecting mechanism of plastic whorl pipe fitting push rod of the present invention is installed push rod in described screw thread fuse, the top of push rod contacts with threaded fitting, and the screw thread fuse is passed in the bottom of push rod; And contact with the top board of the state of ejecting, just top board is when jack-up not, and the bottom of push rod does not contact with top board; Therefore, during the demoulding, at first mould die sinking; Then drive the pinion rotation on the driving shaft by power, pinion drives gear wheel, and gear wheel drives screw thread fuse rotating stripping demoulding; Be installed in the screw thread fuse and push rod to be installed to follow the rotation of screw thread fuse, deviate from from the screw thread inwall of threaded fitting, drive on the top board by injection machine power again and push up up to the screw thread fuse; Top board is contacted with the push rod bottom, drive push rod threaded fitting is ejected outside the mould, demoulding success.In the screw thread fuse of this programme with the push rod installation, make push rod follow the rotation of screw thread fuse, after the demoulding of screw thread fuse, threaded fitting is ejected outside the mould, guarantee automatic demoulding, enhance productivity.
The rotational automatic ejecting mechanism of plastic whorl pipe fitting push rod of the present invention is equipped with the piece that automatically resets on the described push rod, on the piece that automatically resets automatic-reset spring is installed, and automatically resets after making push rod by last top.Be equipped with the 3rd bearing, the 4th bearing and the 5th bearing between described screw thread fuse and the dynamic model backing plate, a plurality of bearings make screw thread fuse spin stabilization.
