Technical field
The present invention relates to a kind of glue mouth mould, especially relate to and in a kind of slide block, enter to slip into glue mouth mould.
Background technology
At present, injection mold glue-feeder has a variety of, such as: side Jiao Kou, some Jiao Kou, fan-shaped Jiao Kou, ox horn enter glue mouth etc.But these Jiao Kou to be used in and in slide block, have great difficulty, because slide block is to move, so cannot design thimble in slide block, Jiao Kou is ejected, side Jiao Kou designs in front mold, designs an overhead kick on slide block, during die sinking, utilize slide block overhead kick that side Jiao Kou is pulled on slide block, by sliding motion, overhead kick is deviate from, although side Jiao Kou design bothers a bit on slide block, structure is still set up again, but on slide block, Jiao Kou is slipped in design, cannot realize according to a conventional method.
Summary of the invention
Object of the present invention is exactly to provide in a kind of slide block that does not need to prune Jiao Kou, reduce costs and enter to slip into glue mouth mould in order to overcome the defect of above-mentioned prior art existence.
Object of the present invention can be achieved through the following technical solutions:
In a kind of slide block, enter to slip into glue mouth mould, comprise the upper module being formed by the I-shaped plate, flow distribution plate, upper plate and the push pedal that set gradually and the lower module being formed by the lower plate setting gradually, square iron, face needle plate, end needle plate and base plate from top to bottom from top to bottom, wherein, Jiao Kou and slide block are slipped in the matched moulds setting of upper module and lower module.
The described bottom of slipping into Jiao Kou connects nonstandard thimble, and the outside of this nonstandard thimble is arranged with the back-moving spring mating with it, and the bottom of nonstandard thimble is provided with the nonstandard thimble pressing plate mating with it.
Described slide block is located at the outside of nonstandard thimble.
In described lower module, be equipped with thimble and back-moving spring, described thimble is located between end needle plate, face needle plate, square iron and lower plate from bottom to top, and described back-moving spring is located between end needle plate and face needle plate.
When injection moulding machine mould open, in slide block, nonstandard thimble back-moving spring moves together with slide block, while extracting slide block out, slide block stops sliding, when slide block stops, the nonstandard thimble in slide block just in time eject thimble just above, when injection machine ejecting mechanism, while ejecting upper and lower panel, thimble pushes up nonstandard thimble, thereby eject, slips into Jiao Kou.When injection machine ejecting mechanism is return, back-moving spring is return top and bottom needle plate, and thimble is fixed on upper and lower panel, so thimble is also return together with the pin of top and bottom, nonstandard thimble is return reset under the effect of spring force, injection machine matched moulds, thus complete a production cycle.
Compared with prior art, the present invention has the following advantages:
(1) on the Surface Appearance that utilizes the present invention to make to obtain, there is no glue mouth vestige, meet the requirement of client to product;
(2) need not remove again to prune Jiao Kou, reduce cost of labor.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
In a kind of slide block, enter to slip into glue mouth mould, its structure as shown in Figure 1-2, comprise the upper module being formed by the I-shaped plate 1 setting gradually,
flow distribution plate 2,
upper plate 3 and
push pedal 4 and the lower module being formed by the
lower plate 5 setting gradually,
square iron 6, face needle plate 7,
end needle plate 8 and
base plate 9 from top to bottom from top to bottom, wherein, in the matched moulds setting of upper module and lower module, slip into
glue mouth 10 and slide block 11.The bottom of slipping into
glue mouth 10 connects
nonstandard thimble 12, and the outside of this
nonstandard thimble 12 is arranged with the nonstandard thimble back-moving
spring 13 mating with it, and the bottom of
nonstandard thimble 12 is provided with the nonstandard
thimble pressing plate 14 mating with it.
Slide block 11 is located at the outside of
nonstandard thimble 12.
In lower module, be equipped with
thimble 15 and back-moving
spring 16,
thimble 15 is located between
end needle plate 8, face needle plate 7,
square iron 6 and
lower plate 5 from bottom to top, and back-moving
spring 16 is located between
end needle plate 8 and face needle plate 7.
When injection moulding machine mould open, 11 li of nonstandard thimble back-moving
springs 13 of slide block move together with
slide block 11, while extracting
slide block 11 out,
slide block 11 stops sliding, when
slide block 11 stops, the
nonstandard thimble 12 that slide block is 11 li just in time thimble 15 just above, when injection machine ejecting mechanism, while ejecting upper and lower panel, the
thimble 15 nonstandard thimbles 12 in top, slip into Jiao Kou thereby eject.When injection machine ejecting mechanism is return, back-moving
spring 16 and nonstandard thimble back-moving
spring 13 are return top and bottom needle plate,
thimble 15 is fixed on upper and lower panel, so
thimble 15 is also return together with the pin of top and bottom,
nonstandard thimble 12 is return reset under the elastic force effect of nonstandard thimble back-moving
spring 13, injection machine matched moulds, thus complete a production cycle.
