fig. 2 is a sectional view of the mold opening of the present invention.

Detailed Description

As shown in fig. 1 and 2, the utility model relates to a hidden oblique runner injection mold, including fixed die plate 1, take off flitch 2, cavity plate 3, movable mould bottom plate 4, draw material round pin 5, guide pillar 6, slider 7, front mould benevolence 8, back mould benevolence 9 to one side.

The fixed die plate 1, the stripper plate 2, the female die plate 3 and the movable die bottom plate 4 are sequentially overlapped together, the front die core 8 is fixed on the female die plate 3, the rear die core 9 is fixed on the movable die bottom plate 4, and the front die core 8 is arranged opposite to the rear die core 9; the upper end of the pulling pin 5 is fixed on the fixed die plate 1, the lower end of the pulling pin 5 extends into the runner and is opposite to the hidden inclined pouring gate, the upper end of the inclined guide post 6 is fixed on the female die plate 3, the lower end of the inclined guide post 6 is movably sleeved in a guide hole 71 at the outer end of the sliding block 7, the sliding block 7 is connected on the movable die base plate 4 in a sliding manner and is positioned between the front die core 8 and the rear die core 9, and the inner end of the sliding block 7 extends into the die cavity; the upper section of the hidden inclined pouring gate 10 is arranged in the front die core 8, and the lower section of the hidden inclined pouring gate 10 is arranged at the inner end of the sliding block 7.

The utility model discloses a theory of operation:

1. after the machine station is assembled, the product 100 is injection molded by using a stub bar channel formed by the sprue bush, the front mold core 8, the female mold plate 3, the front mold core 8 and the slide block 7.

2. When the mold is opened, the stripper plate 2 and the front mold core 8 are preferentially separated from the female mold plate 3 under the action of the pull rod spring, and the pull pin 5 breaks the hidden inclined pouring gate 10 to realize primary parting.

3. The mold opening action is continued, under the action of the pull rod, the stripper plate 2 is separated from the female mold plate 3, and the stub bar is separated from the material pulling pin 5, so that secondary parting is realized.

4. And the mold opening action is continued under the driving of the inclined guide post 6, the slide block 7 looses the core, and the movable mold and the fixed mold are thoroughly separated, so that the third parting is realized.

5. After the mold is opened, the product 100 is ejected out under the action of the ejection mechanism.

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.
