With the presence of technology mould is complicated, injecting products when injection cycle length, scrappage is high the problems such as, in order to further improve modeling
Materials and parts production efficiency, reduction working of plastics scrappage to the mould of prior art, it is necessary to be improved improvement.
Utility model content
The purpose of this utility model is that providing a kind of plastic mould twists the detent mechanism that pitch thread originates tooth, with solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of plastic mould twists the detent mechanism that pitch thread originates tooth, including hydraulic motor, hydraulic motor fixed plate, regulation
Gear, regulation cam, chain, thread core and push pedal；Be provided with the hydraulic motor fixed plate hydraulic motor, limited post and
Regulation gear is installed on spring, the power transmission shaft of hydraulic motor, regulation cam is installed outside regulation gear, regulation cam with it is spacing
Post is contacted, the outer sheathed spring of limited post；The regulation gear and the first sprocket coaxiality are set, and the first sprocket wheel passes through chain and second
Sprocket wheel is connected；Second sprocket wheel is arranged on gear shaft, first gear is provided with gear shaft, first gear is with being arranged on spiral shell
Second gear engagement outside line core, second gear and thread core coaxial linkage；The thread core contacts connection with push pedal,
Push pedal spring is installed in push pedal.
It is used as further program of the utility model：The first gear is identical with size, the size of second gear.
It is used as the utility model further scheme：The regulation gear is set with regulation cam coaxial, adjusts gear
Engaged with regulation cam inwall periphery.
It is used as the utility model further scheme：One is provided with the regulation cam is used to stop limited post
Spacing preiection.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, mould
Have after fixed and moving opening, drive thread core to turn clockwise counterclockwise by hydraulic motor transmission axle, and by means of push pedal in push pedal
The active force of spring draws off working of plastics from screw thread；After working of plastics pickup terminates, driven clockwise by hydraulic motor transmission axle
Thread core rotate counterclockwise, stops operating when hydraulic motor transmission axle is rotated to regulation cam limit high spot, thread core
After rotation is screw initial thread tooth position, the fixed and moving closure of mould to home position, start another wheel operation cycle；It is with short production cycle,
Reduce mould and move back the mould time, improve production efficiency；Production precision and die table are improved, product rejection is reduced
Rate, so as to be obviously improved enterprise competitiveness and economic benefit.
