Abstract
The invention discloses a push plate ejection mechanism of an injection mold system; the push plate ejection mechanism mainly comprises a push plate, a push rod and a male mold insert, wherein the push rod is fixedly connected with the push plate through an end screw; the push plate is fixedly connected with a slide seat through a bolt; a runner is formed between the slide seat and the male mold insert; a product buckle is formed at the junction of the corner of the male mold insert and the runner; a T-shaped deflector piece is arranged on the slide seat; the axial direction of the short axis of the T-shaped deflector piece is provided with the runner, and a tapered slot is formed at the position of the long axis crossed with the runner; the tapered slot is cooperated with a thimble which has a tapered head and is located under the tapered slot; the thimble is connected with a thimble plate located under the thimble. By using the push plate ejection mechanism provided by the technical scheme of the invention, a product is pushed out, and simultaneously the runner is cut off automatically, especially the exit of a thin-wall product can be protected well.
Description
Technical field
The present invention relates to injection mold field, be specifically related to a kind of ejecting push plate mechanism of injection mold system.
Background technology
Injection mold production process, if product wall is thinner, is not suitable for directly ejecting with conventional thimble, otherwise easily distortion is damaged.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of ejecting push plate mechanism of injection mold system is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of ejecting push plate mechanism of injection mold system, mainly comprise push pedal, push rod and male model mold insert, described push rod is fixed together by end face screw and described push pedal, described push pedal is fixed together by bolt and line position seat, between described line position seat and male model mold insert, form runner, form product button at the corner of described male model mold insert and the intersection of runner.
Preferably, on described line position seat, be provided with T-shaped conducting element, described runner is through the minor axis of described T-shaped conducting element, is provided with cone tank in the major axis position intersecting with runner, described cone tank matches with the thimble with taper top of below, and described thimble connects the ejector retainner plate of below.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, when product can being released together, automatically cut off runner, especially exiting of thin wall product had to extraordinary protection.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.

Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of ejecting push plate mechanism of injection mold system, mainly comprise push pedal 1, push rod 2 and male model mold insert 3, described push rod 2 is fixed together by end face screw 4 and described push pedal 1, described push pedal 1 is fixed together by bolt 5 and line position seat 6, between described line position seat 6 and male model mold insert 3, forms runner 7, forms product button 71 at the corner of described male model mold insert 3 and the intersection of runner 7.
On described line position seat 6, be provided with T-shaped conducting element 61, described runner 7 is through the minor axis 611 of described T-shaped conducting element 61, be provided with cone tank in T-shaped conducting element 61 major axis 612 positions that intersect with runner 7, described cone tank matches with the thimble 8 with taper top 81 of below, and described thimble 8 connects the ejector retainner plate 9 of below.
Respectively be provided with a male model mold insert 3 in T-shaped conducting element 61 both sides, male model mold insert 3 is fixed on support 10 by screw 31.
Principle of the present invention:
When mechanism kinematic, injection machine ejection system moves upward ejector retainner plate 9, head into by the taper of thimble 8 in the cone tank of T-shaped conducting element 61 and first cut off runner, continue again to eject, push rod 2 tops are released product button 71 together to push pedal 1, until product button 8 exits completely, closed action process in contrast.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
