Abstract
The invention discloses a kind of mould thread mold insert pulled core structure, thread mold insert includes insert body, insert body lower end is equipped with insert body external screw thread, mold insert regulating wheel is rotary with insert body external screw thread, mold insert regulating wheel is equipped with regulating wheel serration, the side of thread mold insert is equipped with rack, and rack is equipped with the closely-pitched coordinated with regulating wheel serration.For the present invention after drive rack pulls back and forth, the closely-pitched on rack drives the regulating wheel serration of mold insert regulating wheel to rotate, and also just drives mold insert regulating wheel to rotate, so as to drive insert body to rotate, completes core pulling action.The present invention is coordinated using the closely-pitched on rack and the regulating wheel serration of mold insert regulating wheel, so as to improve the precision of thread mold insert core pulling, improves yield rate.Simple in structure, easy for installation, cost is low, and precision is high, reliable product quality.
Description
【Technical field】
The present invention relates to a kind of mould thread mold insert pulled core structure.
【Background technology】
As die-cast part is large-scale in application in the industrial production, walked for how to reduce to process in production process
Rapid and processing technology technology, has become the problem of manufacturer's research, the thread mold insert core pulling having in the prior art, is in spiral shell
Tooth mold insert bottom is equipped with base, and base end face is equipped with the multiple holes for lining up a ring, band again is connected with hole by transmission device
Dynamic thread mold insert slides, and this thread mold insert core pulling precision is too low, does not meet product requirement.The thread mold insert having in the prior art
Also there are following defect for core pulling：1st, complicated, installation and removal are inconvenient, and 2, of high cost, add the manufacture cost of mould.
【The content of the invention】
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of simple in structure, easy for installation, cost
Low, precision is high, reliable product quality, the mould thread mold insert pulled core structure of high yield rate.
The object of the present invention is achieved like this：
A kind of mould thread mold insert pulled core structure, it is characterised in that thread mold insert includes insert body, insert body lower end
Equipped with insert body external screw thread, mold insert regulating wheel is rotary with insert body external screw thread, mold insert regulating wheel is equipped with regulating wheel serration,
The side of thread mold insert is equipped with rack, and rack is equipped with the closely-pitched coordinated with regulating wheel serration.
A kind of mould thread mold insert pulled core structure as described above, it is characterised in that gear is further fixed on insert body.
A kind of mould thread mold insert pulled core structure as described above, it is characterised in that one end of rack passes through drive link and driving
Device is connected.
A kind of mould thread mold insert pulled core structure as described above, it is characterised in that insert body is a pipe, its top is set
There is lower small conical head upper greatly, conical head outer rim is equipped with external screw thread.
The beneficial effects of the invention are as follows：
For the present invention after drive rack pulls back and forth, the closely-pitched on rack drives the regulating wheel serration of mold insert regulating wheel to turn
It is dynamic, also just drive mold insert regulating wheel to rotate, so as to drive insert body to rotate, complete core pulling action.The present invention is using on rack
The regulating wheel serration of closely-pitched and mold insert regulating wheel coordinate, so as to improve the precision of thread mold insert core pulling, improve yield rate.
Simple in structure, easy for installation, cost is low, and precision is high, reliable product quality.
【Brief description of the drawings】
Fig. 1 is the structure chart of the present invention.
【Embodiment】
The invention will be further described below in conjunction with the accompanying drawings：
A kind of mould thread mold insert pulled core structure, thread mold insert 1 include insert body 2, and 2 lower end of insert body is equipped with mold insert
This extracorporeal thread 3, is rotary with mold insert regulating wheel 4 on insert body external screw thread 3, mold insert regulating wheel 4 is equipped with regulating wheel serration 5, spiral shell
The side of tooth mold insert 1 is equipped with rack 5, and rack 5 is equipped with the closely-pitched 6 coordinated with regulating wheel serration 5.After rack 5 pulls back and forth, tooth
Closely-pitched 6 on bar 5 drives the regulating wheel serration 5 of mold insert regulating wheel 4 to rotate, and also just drives mold insert regulating wheel 4 to rotate, so as to drive
Insert body 2 rotates, and completes core pulling action.The present invention is using the closely-pitched 6 on rack 5 and the regulating wheel serration 5 of mold insert regulating wheel 4
Coordinate, so as to improve the precision of thread mold insert core pulling, improve yield rate.
Gear 7 is further fixed on insert body 2, another driving part drives thread mold insert 4 by being driven wheeling driving gear 7
Slided, tapping action can be completed.
One end of the rack 5 of the present invention is connected by drive link 8 with driving device.
The insert body 2 of the present invention is a pipe, its top is equipped with lower small conical head upper greatly, and conical head outer rim is equipped with outer
Screw thread.
