Description
Technical field
The utility model relates to technical field of mold, relates in particular to a kind of steering mechanism for many materials or multi-color injection molded mould realization rotation.
Background technology
Modern life product variety is more and more abundanter, and color is also more and more gorgeous and diversified.Double-colored, polychrome, these plastics by various plastics (PB, PE etc.) or various color of many materials mix the Injection moulded part that hangs together and use also more and more widely.This Injection moulded part of taking that mixes needs some special flow processs in forming process, also need mould and machine to cooperate and realize multiple or polychrome material difference injection moulding desired position to turn to different angles.Required rotating mechanism during current this type of mould molding, the basic rotating disks that all rely on the former factory of injection machines mechanically to be equipped with.Rotating disk drives the mould rotation, makes mould rest on moulding on the position of the angle that need turn to.And the rotating disk that former factory is equipped with generally has only standard angle, and as 180 degree, 120 degree etc., when much designing complicated product moulding, standard angle can't realize that its many materials or polychrome mix the moulding demand of taking.Especially now product design is various, and the angle of restriction differs and reaches the effect that needs surely.The result is because of the restriction of standard angle, and some good designs but can not be made the product that good product maybe can not be made desirable effect.
Therefore can also entrust the former factory of injection machine customization rotating disk now, the required angle of demand customization according to molded article, but the expense of customization rotating disk is very expensive, cost is very high, if customization, basically the rotating disk that is customized can only be fit to customize that a kind of product of rotating disk for this reason, can't be general on other product.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of steering mechanism of injection mold, and it is with high costs to solve prior art, and can not realize the defective that any direction and angle can both be rotated.
Technical scheme
A kind of steering mechanism of injection mold is characterized in that: include the product mould 1 to be formed in belt carcass chamber, described product mould to be formed 1 core chamber connects a rotating shaft 2, and rotating shaft 2 other ends connect tumbler.
Described tumbler is an electric rotating machine, and described rotating shaft 2 is connected on the output shaft of electric rotating machine.
Described tumbler is included in the outer vertical rotation axis 2 axis faces of rotating shaft 2 circumference and cooperates the rotating shaft cover of installing 3, rotating shaft cover 3 is protruding at an end of vertical rotation axis 2, the section of stretching out is plugged into the central circular hole of central gear 4, and central gear 4 meshes with driving tooth bar 5, and driving on the tooth bar 5 has travel switch 7.
Described central gear 4 and 5 of driving tooth bars pass through gear 8 engagements, and described gear 8 forms planetary gearsets with central gear 4.
Described gear 8 is one group of in-line gears, the driven pulley 82 of in-line gears and central gear 4 engagements, driving wheel 81 and 5 engagements of driving tooth bar.
Described driving tooth bar 5 connects oil cylinder 6.
At driving tooth bar 5 one stroke switch 7 is installed respectively up and down.
It is polygon that 3 inner surfaces are overlapped in described rotating shaft, and described rotating shaft 2 is being overlapped the circular radial side face of 3 cooperation places with rotating shaft and shape that 3 inner surfaces are overlapped in rotating shaft is complementary.
Beneficial effect
The utility model utilizes tumbler to drive the core chamber that rotating shaft is connected to mould to be formed, can realize mould to be formed arbitrarily, the rotation of unconfined angle, the selection of tumbler can also make the control of the anglec of rotation reach the requirement of required accuracy, thereby fundamentally improves the bottleneck problem in present many materials and the polychrome mould molding, realizes the freedom that product design and product are made, but also it is with low cost, easy to operate, can repeatedly recycle, versatility is extremely strong.
Description of drawings
Fig. 1 is the schematic diagram of rotating shaft cover band gear train for the utility model tumbler.
Fig. 2 is the A portion concrete structure schematic diagram among Fig. 1 in the utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of universal steering mechanism of injection mold, comprise product mould 1 to be formed, product mould to be formed 1 core chamber connects a rotating shaft 2, rotating shaft cover 3 is equipped with in the vertical rotation axis 2 axis faces cooperation outside circumference of rotating shaft 2 other ends, rotating shaft cover 3 ends at vertical rotation axis 2 stretch out outside cylinder, be plugged into the central circular hole of central gear 4, central gear 4 meshes with the driving tooth bar 5 of band oil cylinder 6, and driving tooth bar 5 respectively has one stroke switch 7 up and down.
Described central gear 4 and 5 of driving tooth bars pass through 8 engagements of one group of in-line gears, the driven pulley 82 of described in-line gears 8 and central gear 4 engagements, driving wheel 81 and 5 engagements of driving tooth bar.
It is polygon that 3 inner surfaces are overlapped in rotating shaft, and described rotating shaft 2 is being overlapped the circular radial side face of 3 cooperation places with rotating shaft and shape that 3 inner surfaces are overlapped in rotating shaft is complementary.
The diameter that inserts rotating shaft one side is big.
Rotating shaft 2 connects the injection machine ejection system.
The utility model course of work is: rotating shaft 2 is advanced under the injection machine ejection system promotes, directed circumference front end inserts rotating shaft cover 3 in the rotating shaft 2, oil cylinder 6 is worked under injection machine is loosed core system pressure, drive driving tooth bar 5 one-way movements that are connected with oil cylinder 6, drive the driving wheel 81 that tooth bar 5 promotes in-line gears 8, driven pulley 82 drives central gear 4 and rotates, and central gear 4 related rotating shaft covers 3 and rotating shaft 2 are rotated.Rotational angle by oil cylinder about in the of 6 travel switch 7 determine.After rotating shaft 2 fixing product mould 1 core chambeies turned to desired location, rotating shaft 2 retreated to original position, did moulding and prepared, and directed circumference front end breaks away from rotating shaft cover 3 in the rotating shaft 2.Oil cylinder 6 drags driving tooth bar 5 and writes in reply to moving to the home position, does circulation next time and prepares.
It is identical with rotating shaft 2 directed circumference coupling place shapes that 3 inner structures are overlapped in the rotating shaft of the utility model core, and for polygon designs, one big, and one little, is convenient to driving fit and disengaging, cooperates the stroke of tooth bar 5 to change into the required rotational angle of rotating shaft 2 simultaneously.
Rotating shaft 2 also can directly connect the output shaft of electric rotating machine etc., also can drive product mould 1 and rotate up and down.But the accuracy of motor is not high, and angle of rotating in control or status requirement adopt the accuracy of said gear group very high very accurately the time, and the result of use on precision die is very good.
