An object of the utility model is to provide an injection mold's ejection mechanism that processing is convenient, the action is reliable.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to an ejection mechanism of an injection mold, which comprises a movable mold core, an inclined ejector rod and an ejector rod; the movable mould core is provided with an oblique top groove, the middle part of the oblique ejector rod movably penetrates into the oblique top groove of the movable mould core, the upper part of the oblique ejector rod penetrates through the oblique top groove of the movable mould core and then extends into the mould cavity, the lower end of the oblique ejector rod is in sliding connection with the upper end of the ejector rod, the lower end of the oblique ejector rod can transversely move relative to the upper end of the ejector rod, and the lower end of the ejector rod is connected with the top plate.
The lower end of the inclined ejector rod is provided with a T-shaped groove, the upper end of the ejector rod is provided with a T-shaped block, and the T-shaped block at the upper end of the ejector rod is connected in the T-shaped groove at the lower end of the inclined ejector rod in a sliding mode.
The utility model also comprises a guide block; the middle part of the ejector rod is movably arranged in a guide groove or a hole of the guide block in a penetrating way.
The upper end of the inclined ejector rod is provided with a groove.
After the scheme is adopted, because the utility model discloses a movable mould benevolence, oblique ejector pin, guide block, ejector pin, oblique ejector pin is shorter, swing distance is less, can directly process out oblique groove in movable mould benevolence, and the recess that no debris fell into on the movable mould benevolence has the advantage that processing is convenient, the action is reliable.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description
As shown in fig. 5-8, the present invention relates to an ejection mechanism of an injection mold, which comprises a movable mold core 1, an inclined ejector rod 2, a guide block 3, and an ejector rod 4.
The movable mould core 1 is provided with an oblique top groove 11, the middle part of the oblique ejector rod 2 movably penetrates through the oblique top groove 11 of the movable mould core 1, the upper part of the oblique ejector rod 2 penetrates through the oblique top groove 11 of the movable mould core 1 and then extends into the mould cavity, the lower end of the oblique ejector rod 2 is in sliding connection with the upper end of the ejector rod 4, the lower end of the oblique ejector rod 2 can transversely move relative to the upper end of the ejector rod 4, the middle part of the ejector rod 4 movably penetrates through a guide groove (or a hole) 31 of the guide block 3 to prevent the ejector rod 4 from shaking during working, and the lower end of the ejector rod 4 is connected with a top plate (not seen in the drawing). In this embodiment, referring to fig. 9, a T-shaped groove 21 is formed at a lower end of the oblique top bar 2, a T-shaped block 41 is disposed at an upper end of the top bar 4, the T-shaped block 41 at the upper end of the top bar 4 is slidably connected in the T-shaped groove 21 at the lower end of the oblique top bar 2, an accommodating groove 22 (as shown in fig. 5) for accommodating a bump 101 of a molded product 10 is disposed at the upper end of the oblique top bar 2, and when the oblique top bar 2 is pushed upwards by the top bar 4, the T-shaped block 41 at the upper end of the top bar 4 slides in the T-shaped groove 21 formed at the lower end of the oblique top bar 2, so that the groove 22 at the upper end of the oblique top bar 2 can be separated from the bump 101 of the product 10. Because the inner side walls of the product 10 in this embodiment are symmetrically provided with the protrusions 101, two symmetrical oblique top rods 2 are correspondingly provided.
The utility model discloses a theory of operation:
the ejector rod 4 is ejected upwards from the bottom in the ejection of the top plate, the ejector rod 4 ejects the oblique ejector rod 2 upwards, the T-shaped groove 21 at the lower end of the oblique ejector rod 2 and the T-shaped block 41 at the upper end of the ejector rod 4 slide relatively along the transverse direction, the upper end of the oblique ejector rod 2 moves inwards, the groove 22 at the upper end of the oblique ejector rod 2 can be separated from the bump 101 of the product 10, and the product 10 is ejected from the upper end of the oblique ejector rod 2.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
