The utility model discloses still include oblique guide pillar briquetting, this fixed cover of guide pillar briquetting connects the upper end at oblique guide pillar to one side.

A gap is formed between the lower part of the inclined guide post and the inclined hole of the sliding block to form a clearance.

After the scheme of the above, because the utility model discloses a movable mould benevolence, the movable mould mold insert, a spring, the seesaw piece, the pivot, inlay the needle, shovel base, the slider mold insert, oblique guide pillar, the movable mould mold insert forms the seesaw structure through the seesaw piece with inlaying the needle, under the mould state that closes, the movable mould mold insert stretches into the die cavity under the roof pressure of inlaying the needle, under the die sinking state, it loses the pressure of supporting to the movable mould mold insert to inlay the needle, the movable mould mold insert breaks away from fashioned product under the effect of spring for the slider mold insert breaks away from the back-off on the product under the drive of oblique guide pillar.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Drawings

FIG. 1 is a cross-sectional view of the closed mold of the present invention;

FIG. 2 is a sectional view of the mold opening process of the present invention;

fig. 3 is a sectional view of the complete mold opening of the present invention.

Detailed Description

As shown in fig. 1, the utility model relates to an injection mold seesaw demoulding mechanism, including movable mould benevolence 1, movable mould mold insert 2, spring 3, seesaw piece 4, pivot 5, inlay needle 6, shovel base 7, slider 8, slider mold insert 9, oblique guide pillar 10, oblique guide pillar briquetting 20.

The movable mould core 1 is fixed on a movable mould plate, the upper end of the movable mould insert 2 is movably arranged in a stepped groove 11 of the movable mould core 1 in a penetrating manner, the upper end surface of the movable mould insert 2 extends into a mould cavity, the lower end surface of the movable mould insert 2 is abutted against one end of a seesaw block 4, the middle part of the seesaw block 4 is movably sleeved on a rotating shaft 5, the rotating shaft 5 is fixed on the movable mould plate, the other end of the seesaw block 4 is abutted against the lower end surface of an insert pin 6, the upper part of the insert pin 6 is movably arranged in a pin hole 12 of the movable mould core 1 in a penetrating manner, the upper end surface of the insert pin 6 penetrates into a parting surface so as to be abutted against a fixed mould plate, a spring 3 is arranged in the stepped groove 11 of the movable mould core 1, and two ends of the spring 3 are respectively abutted against a hanging platform 21 of the movable mould insert 2 and the stepped surface of the stepped groove 11; the upper end of the shovel base 7 is fixed on the fixed template, the inner side wall of the lower part of the shovel base 7 is pressed against the outer end of the sliding block 8 in an inclined surface matching mode, the inner end of the sliding block 8 is connected with the outer end of the sliding block insert 9 and is connected to the movable template in a sliding mode, the inner end of the sliding block insert 9 extends into the cavity, the lower part of the inclined guide post 10 is movably arranged in an inclined hole 81 of the sliding block 8 in a penetrating mode, and a gap is formed between the lower part of the inclined guide post 10 and the inclined hole 81 of the sliding block 8 to form clearance avoidance; the inclined guide post pressing block 20 is fixedly sleeved at the upper end of the inclined guide post 10, and the inclined guide post pressing block 20 is fixed on the fixed die plate.

The utility model discloses a theory of operation:

1. when the fixed mold core and the movable mold core 1 are in a mold closing state, the insert pin 6 always pushes against the seesaw block 4 due to the pressure of the movable mold core 1, the seesaw block 4 upwards drags the movable mold insert 2 by taking the rotating shaft 5 as an axis, and the spring 3 is in a stressed extrusion state at the moment.

2. As shown in fig. 2, when the mold is opened, when the inclined guide post 10 is attached to the slide block 8 to a certain distance, the insert pin 6 has no pressure of the movable mold core 1, the spring 3 is in an extended state at this time, the movable mold core 2 is ejected out to press the seesaw block 4, and the seesaw block 4 ejects the insert pin 6 upwards by taking the rotating shaft 5 as an axis.

3. As shown in fig. 3, when the inclined guide post 10 is attached to the slide block 8, the mold opening is continued, the inclined guide post 10 drives the slide block 8 and the slide block insert 9 to exit outwards at this time, and since the movable mold insert 2 exits a part first in the previous step, the mouth of the product 100 can be slightly deformed, so that the slide block insert 9 exits the back-off 101 of the product 100 more easily.

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.
