Description
Technical field
The utility model relates to a kind of injection mould structure, particularly a kind of rotating stripping demoulding structure on injection mould.
Background technology
For the drum type product stripping method of internal diameter distribution rule spiral bar shaped, existing technical method adopts ejecting push plate, product self rotates along spiral bar shaped and exits, shortcoming is that product is subject to spiral bar shaped extruding when ejecting causes product to be scraped off seriously, time serious, product directly bursts, there is a lot of uncertain factor during production and cause damage to product, the qualification rate of product is very low, causes a large amount of wastings of resources.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of rotating stripping demoulding structure on injection mould, overcomes the extruding produced product by product self rotating stripping demoulding and the damage caused, improves product percent of pass.
To achieve these goals, a kind of rotating stripping demoulding structure on injection mould designed by the utility model, comprise dynamic model core rod, the upper ejector retainner plate be fixedly connected with and lower ejector retainner plate, and injection machine top rod, described dynamic model core rod comprises the profiled part of upper part and the rotary driving part of lower part, described rotary driving part periphery is provided with the helicla flute of helical pitch identical with product, some driving keys are provided with between described upper ejector retainner plate and lower ejector retainner plate, described driving key end and helicla flute match, described upper ejector retainner plate and lower ejector retainner plate are provided with the perforate can passed for rotary driving part, when injection machine top rod drives upper ejector retainner plate and lower ejector retainner plate up to move, drive key to promote dynamic model core rod to rotate.
Further, the top and bottom of described rotary driving part are equipped with bearing, are conducive to the rotation of dynamic model core rod.
Further, the number of described driving key is three.
Injection machine top rod promotes upper ejector retainner plate and lower ejector retainner plate moves upward, drive and drive key upwards to do rectilinear motion, match owing to driving the helicla flute on key end and rotary driving part periphery, when driving key up to move, driven rotary driver part rotates, thus dynamic model core rod is rotated, meanwhile, push pedal promotes product stripping, anti-rotation groove or stopper slot can be designed in product end surface, ensure that product does not rotate in ejection process, thus realize that product limit ejects and the action of loosing core is rotated on dynamic model core rod limit, namely achieve by product rotation loose core be converted into dynamic model core rod rotate loose core, avoid in product stripping process the power that is squeezed, solve product to scrap because of the power of being squeezed, substantially increase product percent of pass, thus reduction production cost.
A kind of rotating stripping demoulding structure on injection mould that the utility model obtains; its technique effect is: this rotation stripping mechanism solves similar products and produces excessive extruding force by product self rotating stripping demoulding to product; the impact of the uncertain factor existed when overcoming product stripping and damage product; improve the qualification rate of product, thus reduce injection moulding production cost.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1, shown in 2, a kind of rotating stripping demoulding structure on injection mould that the utility model provides, comprise dynamic model core rod 1, the upper ejector retainner plate 2 and the lower ejector retainner plate 3 that are fixedly connected with, and injection machine top rod 4, described dynamic model core rod 1 comprises the profiled part 11 of upper part and the rotary driving part 12 of lower part, described rotary driving part 12 periphery is provided with the helicla flute 13 of helical pitch identical with product, be provided with three between described upper ejector retainner plate 2 and lower ejector retainner plate 3 and drive key 5, described driving key 5 end and helicla flute 13 match, three drive key 5 to be evenly distributed on rotary driving part 12 periphery and end is positioned at swivelling chute, described upper ejector retainner plate 2 and lower ejector retainner plate 3 are provided with the perforate can passed for rotary driving part 12, when injection machine top rod 4 drives upper ejector retainner plate 2 up to move with lower ejector retainner plate 3, drive key 5 to promote dynamic model core rod 1 to rotate.
In order to make dynamic model core rod 1 rotate smoothly, the top and bottom of described rotary driving part 12 are equipped with bearing, do not mark in figure.
When injection machine top rod 4 does not have the upper ejector retainner plate of promotion and lower ejector retainner plate to move upward, this rotating stripping demoulding structure as shown in Figure 1, injection machine top rod 4 promotes upper ejector retainner plate 2 and moves upward with lower ejector retainner plate 3, drive and drive key 5 upwards to do rectilinear motion, match owing to driving the helicla flute 13 on key 5 end and rotary driving part 12 periphery, when driving key 5 up to move, driven rotary driver part 12 rotates, thus dynamic model core rod 1 is rotated, as shown in Figure 2, meanwhile, push pedal promotes product stripping, anti-rotation groove or stopper slot can be designed in product end surface, ensure that product does not rotate in ejection process, thus realize that product limit ejects and the action of loosing core is rotated on dynamic model core rod 1 limit, namely achieve by product rotation loose core be converted into dynamic model core rod 1 rotate loose core, avoid in product stripping process the power that is squeezed, solve product to scrap because of the power of being squeezed, substantially increase product percent of pass, thus reduction production cost.
