Abstract
The utility model provides a kind of rack-and-pinion side core-pulling mechanism, and including sliding block, bearing is installed in sliding block, and lateral thread core is inserted into from the one side of sliding block in bearing, and cylinder one is located at the opposite side of sliding block, and cylinder one drives sliding block along guide pad displacement；One end of rack is connected with the telescopic rod of cylinder two, and the other end is located at the lower section of lateral thread core, the tooth socket engagement connection of driving tooth wheel and rack；Lateral thread core, which is located on the part outside sliding block, to be arranged there are one driven gear, and driving gear is engaged with driven gear, and lateral thread core is driven to rotate.Said mechanism is mounted in dynamic model when in use, and cylinder one drives sliding block to decorporate to side and carries out core pulling, and at the same time, two drive rack of cylinder detaches outside mold, and under engagement, driven gear, which rotates, drives lateral thread core to be rotated in sliding block；Since side slide block core also has the trend of linear motion, lateral thread core realizes straight line and rotating stripping demoulding is added to run.
Description
Technical field
The utility model is related to injection mold technologies, particularly relate to a kind of rack-and-pinion side core-pulling mechanism.
Background technology
In injection mold, in order to ensure the smooth demoulding of product, some side core-pulling mechanisms are often set in a mold
And lifter demoulding mechanism, side core-pulling mechanism are directed to the demoulding of article outer surface, lifter demoulding mechanism is interior between being directed to
The demoulding on surface.
For the product with internal thread feature, rotating stripping demoulding is needed, but existing rack-and-pinion mould emptier is all
It is the screw thread demoulding for vertical type, is not particularly suited for the screw thread demoulding of side-extract type.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of rack-and-pinion side core-pulling mechanisms, can be suitable for
The screw thread demoulding of side-extract type.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
Rack-and-pinion side core-pulling mechanism, including sliding block, lateral thread core, cylinder one, rack, driving gear and cylinder
Two；Bearing is installed in the sliding block, the lateral thread core is inserted into from the one side of the sliding block in the bearing, the gas
Cylinder one is located at the opposite side of the sliding block, and the cylinder one drives the sliding block along the guide pad displacement；The one of the rack
End is connected with the telescopic rod of the cylinder two, and the other end is located at the lower section of the lateral thread core, the driving gear and institute
State the tooth socket engagement connection of rack；The lateral thread core, which is located on the part outside the sliding block, to be arranged there are one driven tooth
Wheel, the driving gear are engaged with the driven gear, and drive the lateral thread core rotation.
It is further also to be arranged on the lateral thread core there are one limiting bush.
Compared with prior art, the beneficial effects of the utility model are：1. said mechanism is mounted in dynamic model when in use,
Cylinder one drives sliding block to decorporate to side and carries out core pulling, and at the same time, two drive rack of cylinder detaches outside mold, makees in engagement
Under, driving gear rotates and driven gear is driven to rotate, and driven gear, which rotates, drives lateral thread core to be rotated in sliding block；
Since side slide block core also has the trend of linear motion, lateral thread core realizes straight line and rotating stripping demoulding is added to transport
Row；2. since driven gear can together be retreated with lateral thread core, driven gear is with respect to the position meeting of driving gear
It changes, limiting bush can prevent driven gear from departing from driving gear.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.
Fig. 1 is the structure diagram of the rack-and-pinion side core-pulling mechanism disclosed in embodiment.
Mark in attached drawing for：
1st, sliding block 2, lateral thread core 3, cylinder 1, rack 5, driving gear 6, cylinder 27, from
Moving gear 8, limiting bush.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Rack-and-pinion side core-pulling mechanism shown in Figure 1, including sliding block 1, lateral thread core 2, cylinder 1, rack
4th, driving gear 5 and cylinder 26；Bearing is installed in sliding block, lateral thread core is inserted into from the one side of sliding block in bearing, cylinder
One is located at the opposite side of sliding block, and cylinder one drives sliding block along guide pad displacement；One end of rack is connected with the telescopic rod of cylinder two,
The other end is located at the lower section of lateral thread core, the tooth socket engagement connection of driving tooth wheel and rack；Lateral thread core, which is located at, to be slided
It is arranged on part outside block there are one driven gear 7, driving gear is engaged with driven gear, and lateral thread core is driven to revolve
Turn.
Said mechanism is mounted in dynamic model when in use, and cylinder one drives sliding block to decorporate to side and carries out core pulling, same with this
When, two drive rack of cylinder detaches outside mold, and under engagement, driving gear rotates and driven gear is driven to rotate, from
Moving gear, which rotates, drives lateral thread core to be rotated in sliding block；Since side slide block core also has the trend of linear motion,
Therefore lateral thread core realizes straight line and rotating stripping demoulding is added to run.
Since driven gear can together be retreated with lateral thread core, driven gear is with respect to the position of driving gear
It can change, driven gear departs from driving gear in order to prevent, so being arranged one on lateral thread core
Limiting bush 8.
A variety of modifications of these embodiments will be apparent for those skilled in the art, herein
The General Principle for moving justice can be real in other embodiments without departing from the spirit or scope of the present utility model
It is existing.Therefore, the utility model is not intended to be limited to the embodiments shown herein, and be to fit to it is disclosed herein
Principle and the consistent most wide scope of features of novelty.
