Description

A kind of rotation stripping mechanism
Technical field
The utility model relates to the injection mo(u)lding field, especially relates to a kind of rotation stripping mechanism.
Background technology
For the demoulding of the injection-molded item (for example screw thread based article) of some special shapes, usually need to adopt the rotary demoulding.Rotation stripping mechanism of the prior art mainly is divided into rack-and-pinion method, motor method, inserts method.The rack-and-pinion method is to utilize the die sinking of injection machine, the process of ejection device, draw to push away the tooth bar engaging tooth crop rotation axial-rotation that is located in the mould emptier, thereby drive core or die cavity rotates ejecting injection molded goods.The motor rule is that utilization is carried out the demoulding at the mould emptier of the motor-driven mould inside of mould outside as axial-rotation.The inserts rule is that the movable inserts of discrete goods is embedded injection mo(u)lding in the mould, taking-up activity inserts, by frock or instrument by manually the screw thread injection-molded item being screwed out from movable inserts.
But, adopt the general volume of injection mold of above-mentioned rack-and-pinion method, the demoulding of motor method comparatively huge, involve great expense.And the auxiliary recruitment of inserts rule is many, and working strength is large, and production efficiency is low.Therefore, how to design the rotation stripping mechanism that cost is low, production efficiency is high and become the technical problem that those skilled in the art need to be resolved hurrily.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of rotation stripping mechanism is provided, and has solved the existing technical problem of prior art.
For achieving the above object; the utility model has adopted following technical proposal: a kind of rotation stripping mechanism; it comprises rotating disk, push rod and driving mechanism; described rotating disk is gear shape; its center is connected with protrudes the core that arranges, and the center of described core is provided with push rod, and described push rod protrudes with respect to core; described driving mechanism and rotating disk engagement are used for driving the central shaft rotation that described rotating disk rotates and coils.
In above-mentioned rotation stripping mechanism, preferably, described driving mechanism is cylinder, and it comprises cylinder barrel and piston rod, and described piston rod is fixed, and is provided with tooth bar on the sidewall of described cylinder barrel, described tooth bar and rotating disk engagement.
In above-mentioned rotation stripping mechanism, preferably, described rotation stripping mechanism has two driving mechanisms, and described two driving mechanisms are connected on the two relative side of rotating disk.
In above-mentioned rotation stripping mechanism, preferably, the groove around core is set around the described core.
Rotation stripping mechanism of the present utility model is simple in structure, cost is low, and by the air cylinder driven dial rotation, realizes rotating stripping demoulding, and its production efficiency is higher.
Description of drawings
Fig. 1 is the structural representation of the first mould that adopts the injection forming mold of the rotation stripping mechanism that the utility model embodiment provides.
Fig. 2 is the structural representation of the second mould that adopts the injection forming mold of the rotation stripping mechanism that the utility model embodiment provides.
The specific embodiment
Please refer to Fig. 1, the rotation stripping mechanism that the utility model embodiment provides comprises rotating disk 4, push rod 5 and driving mechanism.Rotating disk 4 is gear shape, and its center is connected with protrudes the core 42 that arranges.The center of core 42 is provided with push rod 5, and push rod 5 protrudes with respect to core 42, is used for ejecting injection-molded item.4 engagements of driving mechanism and rotating disk are used for driving the rotate central shaft of dish 4 of rotating disk 4 and rotate.
In the present embodiment, driving mechanism is cylinder, and it comprises cylinder barrel 32 and piston rod 34.Piston rod 34 is fixing, is provided with tooth bar 36 on the sidewall of cylinder barrel 32, tooth bar 36 and rotating disk 4 engagements.
In the present embodiment, this rotation stripping mechanism has two driving mechanisms, and two driving mechanisms are connected on the two relative side of rotating disk 4.
In the present embodiment, the setting on every side of core 42 is around the groove 44 of core.
Illustrate below in conjunction with Fig. 1 and Fig. 2 how this rotation stripping mechanism is installed in injection forming mold.
Injection forming mold comprises that the first mould 1 and the second mould 2, the second moulds 2 that match with the first mould 1 are covered on the first mould 1.The first mould 1 roughly is square.Rotating disk 4 is arranged on the first mould 1, and rotating disk 4 and core 42 protrude with respect to the upper surface of the first mould 1.
The second mould 2 also roughly is square, and offers on it be used to the positioning chamber 21 of accommodating rotating disk 4, and the center of positioning chamber 21 offers the die cavity 23 of indent, and die cavity 23 matches with core 42.The center of die cavity 23 offers the nib 25 that matches with push rod 5, is used for passing for push rod 5.
Jointly offer the movable chamber 62 of accommodating cylinder barrel 32 and the connecting hole 64 of accommodating piston rod 34 on the first mould 1 and the second mould 2.The length in movable chamber 62 is greater than the length of cylinder barrel 32, axially tangential along rotating disk 4 of connecting hole 64.Cylinder barrel 32 rotates thereby drive rotating disk 4 in the 62 interior tangential movements along rotating disk of movable chamber.One end of piston rod 34 connects cylinder barrel 32, and the other end passes connecting hole 64, stretches out this injection forming mold, is connected with miscellaneous part.
In the present embodiment, be provided with the bulge loop 27 around die cavity 23 around the die cavity 23, bulge loop 27 matches with core 42 groove 44 on every side, and bulge loop 27 inserts in the grooves 44, and the first mould 1 and the second mould 2 are aimed at.
In the present embodiment, also offer a plurality of locating holes 16 on the first mould 1, accordingly, be provided with a plurality of alignment pins 26 on the second mould 2, when closing the first mould 1 and the second mould 2, alignment pin 26 inserts in the locating hole 16, is convenient to make the first mould 1 and the second mould 2 to aim at.
Rotation stripping mechanism of the present utility model is simple in structure, cost is low, and by the air cylinder driven dial rotation, realizes rotating stripping demoulding, and its production efficiency is higher.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as cylinder, alignment pin, push rod, bulge loop, groove, die cavity, core, movable chamber, connecting hole, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
