Description
Technical field
The invention belongs to injection molding technology field.
Background technology
Injection mold is a kind of instrument producing plasthetics, is also the instrument giving plasthetics complete structure and accurate dimension.Its occupation mode injects in the die cavity of injection mold by the material high pressure melted that is heated, and after cooling curing, obtains formed products.When existing moulding needs to manufacture screw, need to put into thread core in injection mold, after completing injection moulding, threaded moulding is deviate from.
But because threaded moulding and thread core are in the state of threaded engagement, so moulding will be deviate from need first to be exited along its screw thread rotation from injection molding cavity by thread core after die sinking, the mode of current thread core Leave out thread mainly adopts and manually turns thread core, thread core is exited from the threaded portion of moulding, the mode of this Leave out thread is consuming time longer, inefficiency.
Summary of the invention
The invention is intended to provide a kind of short, injection machine Leave out thread mechanism that operating efficiency is high consuming time.
Injection machine in this programme Leave out thread mechanism, comprise dynamic model, shaping mould and thread core successively from top to bottom, groove on dynamic model and the involutory rear formation injection molding cavity of shaping mould end face, thread core upper end is run through shaping mould and is placed in this injection molding cavity, described shaping mould overcoat has can drive the synchronization-moving push pedal of shaping mould, and this push pedal is connected with the die sleeve below push pedal by return spring; This push pedal is provided with the rotating mechanism driving thread core to rotate, and controls the rotary handle of this rotating mechanism.
Beneficial effect: owing to being provided with the push pedal that can drive shaping mould movement, when moulding is released by needs from thread core, rotary handle controls rotating mechanism and starts, rotating mechanism drives thread core to rotate in the screw of moulding, because push pedal is subject to the thrust of return spring, shaping mould is made to be subject to the thrust away from die sleeve, moulding is also subject to this thrust simultaneously, thread core simultaneously in moulding rotates, thread core deviate from by the moulding spiral being so just, realizes the Leave out thread of moulding.Structure of the present invention is simple, without the need to manually directly turning thread core, increases work efficiency while saving manpower.
Further, described rotating mechanism comprises and being horizontally installed on die sleeve and the power transmission shaft affixed with rotary handle, on this power transmission shaft, key is connected with drive bevel gear, thread core lower end spline fitted has driven wheel of differential, drive bevel gear engages with driven wheel of differential, turning handle makes power transmission shaft rotate, and the rotation of drive bevel gear makes driven wheel of differential rotate, thus thread core is rotated.
Further, be provided with stop screw between described push pedal and die sleeve, the threaded portion of this stop screw coordinates with the screw of die sleeve, and the smooth department of stop screw is positioned at the counterbore of push pedal, when push pedal is moved relative to die sleeve, stop screw can limit the displacement of push pedal.
Further, described thread core is divided into thread segment, smooth section and spline segment from top to bottom successively, this spline segment coordinates with the splined hole of driven wheel of differential, the rotation of driven wheel of differential drives thread core integral-rotation, smooth section runs through die sleeve and shaping mould, thread segment stretches in injection molding cavity, forms the threaded portion of moulding during injection moulding.
Further, described power transmission shaft is connected by rolling bearing with die sleeve, reduces friction.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention injection machine Leave out thread mechanism.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: dynamic model 1, shaping mould 2, die sleeve 3, push pedal 4, thread core 5, power transmission shaft 6, drive bevel gear 7, driven wheel of differential 8, turning handle 9, stop screw 10, return spring 11, moulding 12.
Embodiment is substantially as shown in Figure 1: injection machine Leave out thread mechanism, comprises dynamic model 1 and shaping mould 2 from top to bottom successively, this dynamic model 1 is with fluted, and shaping mould 2 end face is relative with this groove and form injection molding cavity.
The bottom of shaping mould 2 contacts with die sleeve 3 end face, and this die sleeve 3 bottom welding has left support abutment and right support abutment, and in the installing hole on left support abutment, interference fit rolls left dynamic bearing, and in the installing hole relative with left bearing of right support abutment, interference fit has right rolling bearing; Between left support abutment and right support abutment, horizontal cross is furnished with power transmission shaft 6, and the left end of power transmission shaft 6 and the inner ring interference fit of the dynamic bearing that rolls left, the axle body of power transmission shaft 6 and right rolling bearing inner ring interference fit, the right-hand member of power transmission shaft 6 welds with turning handle 9.
This power transmission shaft 6 is connected with drive bevel gear 7 by flat key, and this drive bevel gear 7 engages with the driven wheel of differential 8 vertically arranged, the axis hole of this driven wheel of differential 8 is splined hole.Thread core 5 is divided into thread segment, smooth section and spline segment from top to bottom successively, and this spline segment coordinates with the splined hole of driven wheel of differential, and smooth section runs through die sleeve 3 and shaping mould 2, and thread segment stretches in injection molding cavity.
Have the push pedal 4 of annular in shaping mould 2 outer race, this push pedal 4 inner headed face and shaping mould 2 periphery adopt mortise-tenon joint, and the bottom of push pedal 4 is fixedly connected with die sleeve 3 end face by stop screw 10, and the threaded portion of this stop screw 10 is insert molded in the screw of mould 2.Push pedal 4 is shaped with counterbore, and smooth department and the counterbore of stop screw 10 are slidably matched, and the head of a nail of this stop screw 10 is positioned at the step of counterbore, are provided with return spring 11 between this push pedal 4 and shaping mould 2.
The operation principle of the present embodiment is: during matched moulds, and dynamic model 1 is pushed to shaping mould 2 tip position through actuating unit (conventional cylinder etc.), and form injection molding cavity, thread core 5 is positioned at this injection molding cavity.After completing injection moulding, actuating unit drives dynamic model 1 away from shaping mould 2, the top of moulding is exposed, owing to having return spring 11 between push pedal 4 and shaping mould 2, return spring 11 is applied to push pedal 4 one power upwards, push pedal 4 drives shaping mould 2 to be applied to the outside power of moulding one, the hand fixed handle of operator, by drive bevel gear 7, driven wheel of differential 8 is rotated, thus thread core 5 rotates, push pedal 4 under the effect of return spring 11 along with moulding moves, until the complete ejecting injection molded chamber of moulding.Stop screw 10 can carry out spacing to the displacement of push pedal 4.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
