Description
【Technical field】
The present invention relates to a kind of transmission mechanism of inlaid piece of mould.
【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 transmission mechanism of the problem, the in the prior art core pulling of thread mold insert of manufacturer's research
Some is using the cooperation of gear wheel and pinion gear, and this drive connection is, it is necessary to calculate gear wheel and the gearratio of pinion gear, stroke
Too long to also need to use gear set, complicated, assembling is inconvenient；Some using rack and pinion cooperation, due to only using
One rack of bar, pulls and promotes all with a rack, and frictional force is too big, and inertia force effect is too big, wears rack and pinion
Very severe, the service life of transmission mechanism is short, it is necessary to often replace, if disconnected in core pulling or tapping, can directly affect
Product, makes product become waste product.
【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 to assembly, cost
Low, precision is high, high yield rate, the transmission mechanism of the inlaid piece of mould of service life length.
The object of the present invention is achieved like this：
A kind of transmission mechanism of inlaid piece of mould, it is characterised in that it includes the first mold insert group being arranged in a row by multiple mold inserts
The second mold insert group is arranged in a row with by multiple mold inserts, spaced apart between the first mold insert group and the second mold insert group, each edge
Part is equipped with a mold insert gear, and transmission shaft is equipped between the first mold insert group and the second mold insert group, and transmission shaft is equipped with and mold insert tooth
The transmission shaft output gear of engagement is taken turns, is additionally provided with transmission shaft input gear on transmission shaft, transmission shaft input gear both sides are engaged with
Pull rack and promote rack.
A kind of transmission mechanism of inlaid piece of mould as described above, it is characterised in that transmission shaft output gear is inputted more than transmission shaft
Gear.
A kind of transmission mechanism of inlaid piece of mould as described above, it is characterised in that transmission shaft output gear is more than mold insert gear.
A kind of transmission mechanism of inlaid piece of mould as described above, it is characterised in that transmission shaft output gear and the first mold insert group
The mold insert gear of two mold inserts of mold insert gear and the second mold insert group of two mold inserts is meshed.
A kind of transmission mechanism of inlaid piece of mould as described above, it is characterised in that pull rack to be promoted by pulling hydraulic oil cylinder driving
Rack is by promotion hydraulic oil cylinder driving.
The beneficial effects of the invention are as follows：
The present invention can drive pulling rack in ejection, pull the rotation of rack drives transmission shaft input gear, transmission shaft
Input gear drives mold insert gear to rotate, and mold insert gear drives mold insert slide downward, completes ejection action, when exiting, driving
Rack is promoted, promotes rack drives transmission shaft input gear to reversely rotate, transmission shaft input gear drives mold insert gear reversely to turn
Dynamic, mold insert gear drives mold insert upward sliding, and action is exited in completion, ejects and exits action and each use respective rack, subtracts
Fall frictional force and inertia force caused by same rack, improve the service life of rack, so as to improve the service life of transmission mechanism.
Simple in structure, easy to assembly, cost is low, and precision is high, high yield rate.
【Brief description of the drawings】
Fig. 1 is the structure chart of the present invention；
Fig. 2 is the structure chart of the present invention；
Fig. 3 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 transmission mechanism of inlaid piece of mould, it includes the first mold insert group 2 being arranged in a row by multiple mold inserts 1 and by multiple
Mold insert 1 is arranged in a row the second mold insert group 3, spaced apart between the first mold insert group 2 and the second mold insert group 3, on each mold insert 1
Equipped with a mold insert gear 4, transmission shaft 5 is equipped between the first mold insert group 2 and the second mold insert group 3, transmission shaft 5 is equipped with and mold insert tooth
The transmission shaft output gear 51 of 4 engagements is taken turns, transmission shaft input gear 52,52 liang of transmission shaft input gear are additionally provided with transmission shaft 5
Side, which is engaged with, pulls rack 6 and promotion rack 7.In ejection, it can drive and pull rack 6, pull rack 6 to drive transmission shaft defeated
Enter gear 52 to rotate, transmission shaft input gear 52 drives mold insert gear 4 to rotate, and mold insert gear 4 drives 1 slide downward of mold insert, complete
Acted into ejection, when exiting, driving promotes rack 7, promotes rack 7 to drive transmission shaft input gear 52 to reversely rotate, and is driven
Axis input gear 52 drives mold insert gear 4 to rotate backward, and mold insert gear 4 drives 1 upward sliding of mold insert, and action is exited in completion, is pushed up
Go out and exit action and each use respective rack, cut frictional force and inertia force caused by same rack, improve making for rack
With the service life, so as to improve the service life of transmission mechanism.
In the present invention preferably：Transmission shaft output gear 51 is more than transmission shaft input gear 52, transmission shaft output gear 51
More than mold insert gear 4.
