Description
Technical field
The utility model is related to injection molding technology field, and in particular to side core-pulling mechanism and injection mold.
Background technology
It is well known that injection mold is the conventional mould for being molded plastic, it is more to mold form by injection mold
The plastic of sample, to meet the various demands of people.And due to the various technological requirements of plastic, therefore need to be opened up in the side-walls of plastic
The structure such as hole or groove, correspondingly, injection mold is provided with corresponding side core-pulling mechanism, with during die sinking by side core-pulling machine
Structure goes to take out ejection action to products formed progress side, realizes and hole or the isostructural purpose of groove are formed on plastic.
As Fig. 1 shows a kind of injection molding workpiece, x directions one end of the plastic forms hollow tube, y directions
One end also forms protuberance, and the protuberance has the rectangular through-hole set in the x-direction, due to the die sinking process of tube
Two small slide blocks being enclosed in the y-direction on the outside of tube are should be first to mold, then by the side core-pulling mechanism in the x-direction,
Side core-pulling is molded the tube；And the die sinking process of protuberance then for first pass through side core-pulling mechanism side core-pulling in the x-direction into
The type rectangular through-hole, then by being enclosed in opening for two master sliders die sinking at two ends on plastic y directions, i.e. tube and protuberance
The order in mould direction conversely, there exist contradiction, be limited by this product structure so that master slider is needed in the rectangular through-hole
Side core-drawing mechanism is moved again after being fully drawn out, but due to board height limitation, it is impossible to design master slider delay, therefore side core-pulling
Each small slide block of mechanism uses cylinder for power, draws the small slide block in the rectangular through-hole completely before two master slider die sinkings
Go out, the small slide block not otherwise being completely pulled out will be influenceed and will be damaged by master slider die sinking, however, in actual production process, the modeling
Cylinder needed for part mould is more, and control is more difficult, causes client to need to prepare more spare part, mould for side core-pulling mechanism in production
Have cost high, and once control failure, sliding block damage parts are caused, production efficiency is also greatly affected.
Utility model content
Therefore, the technical problems to be solved in the utility model be to overcome in the prior art cylinder control cost it is high, volatile
