The side that rack gear is movably arranged on the left side gear mounting base is stated, in the left side gear mounting base and right side gear mounting base
It is equipped with the groove for placing driving cog gear member, the driving cog gear member is small by being arranged a gear wheel and one on transmission shaft
Gear composition, the upper surface of the rack gear be equipped with for the intermeshing rack gear groove of the pinion gear, in the rack gear
The upper surface of mold insert be equipped with for the intermeshing gear rack embedding part groove of the gear wheel.
As a further improvement, on the inside of the left side gear mounting base and on the inside of right side gear mounting base
It is equipped with the inclined platform tilted down, two inclined platforms are oppositely arranged what formation when being combined together moved downward for gear rack embedding part
Guide chute.
As a further improvement, the outer surface of the left side gear mounting base is arranged in by wearing plate for the rack gear
On outer lug boss on.
As a further improvement, the rack gear is movably arranged on wearing plate, and the wearing plate is fixed by screws in
In the outer lug boss.
As a further improvement, several oil grooves are additionally provided on each surface of the gear rack embedding part.
Beneficial effect
It has the beneficial effect that and realizes that moulding is demoulded from side core-pulling using the transmission effect between gear set, structure letter
Single, easy to use, flexible, demoulding is smooth, avoids moulding from damaging during demoulding, improves the production of injecting products
Quality.

Specific embodiment
To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with
Good examples and drawings cooperate detailed description, are described as follows:
As shown in Figs. 1-2, a kind of gear set side core-pulling structure, the left side gear mounting base 1 being oppositely arranged including two pieces
Gear chest, rack gear 3, gear rack embedding part 4 and the driving cog gear member 5 formed when being combined together with right side gear mounting base 2, injection molding
Moulding A after molding is wrapped in the top of gear rack embedding part 4, and gear rack embedding part 4, which tilts down, to be arranged in gear chest, rack gear 3
It is movably arranged on the side of left side gear mounting base 1, is equipped with and is used in left side gear mounting base 1 and right side gear mounting base 2
The groove 11 and groove 21 of driving cog gear member 4 are placed, driving cog gear member 5 is by being arranged a gear wheel 52 and one on transmission shaft 51
Pinion gear 53 form, the upper surface of rack gear 3 be equipped with for the intermeshing rack gear groove 31 of pinion gear 53, in gear rack embedding part
