Referring to fig. 1-3, the preferred embodiment of the present invention is shown.

The headset die easy-demolding slide structure comprises an upper die holder 100 and a lower die holder 200 connected with the upper die holder 100, wherein a molding die cavity for molding a headset die is arranged between the upper die holder 100 and the lower die holder 200, and a slide insert 300 connected with the headset die is arranged on the inner side wall of the molding die cavity; the upper die base 100 is provided with an upper die driving insert 400 for driving the slide insert 300 to move up and down, and the upper die driving insert 400 is pressed against the slide insert 300; a slide fixing block 500 for fixing the up-and-down moving track of the slide insert 300 is arranged between the upper die driving insert 400 and the lower die holder 200, and the slide fixing block 500 is pressed on the lower die holder 200; the slide insert 300 penetrates the slide fixing block 500 from top to bottom.

The above-mentioned earphone mould easy demolding line bit architecture that provides, accomplish the back of moulding plastics when the earphone mould in the moulded die cavity, upwards take out the back with upper die base 100, move along upper die base 100 through last mould drive mold insert 400, and drive and go position mold insert 300 and upwards slide until breaking away from earphone mould back-off region back along the track of going the position fixed block 500 the inside, the automatic demolding of earphone mould, it is loaded down with trivial details to have solved earphone demolding process, can't satisfy the requirement of taking out and the normal production efficiency of product, batch production's problem has been reduced.

The bottom of the slide insert 300 abuts against the earphone mold, and the top of the slide insert 300 abuts against the upper mold drive insert 400. Like this, the bottom of position mold insert 300 of walking is the butt in the inside that the earphone mould was not inserted in the periphery of earphone mould, consequently when position mold insert 300 of walking separates with the earphone mould, also can not cause the damage to the earphone mould, and effectual assurance product presss from both sides the mouth.

In this embodiment, the top of the slide insert 300 has a top block 301 abutting against the upper mold driving insert 400, the slide insert 300 is provided with an elastic member 302 driving the top block 301 to move upward, the top of the elastic member 302 abuts against the bottom of the top block 301, and the bottom of the elastic member 302 abuts against and is pressed in the slide fixing block 500.

After the upper die holder 100 is separated from pressing the upper die driving insert 400, the elastic force of the elastic member 302 drives the ejector block 301 to eject the upper die driving insert 400 upwards, and the ejector block 301 drives the slide insert 300 to move upwards, so that the slide insert 300 slides upwards along the track inside the slide fixing block 500 until being separated from the reverse buckling area of the earphone die.

The upper die driving insert 400 has a chute 401 recessed inward away from the slide insert 300 to form an external opening; the top block 301 abuts against the inside of the sliding groove 401; the inner side wall of the sliding groove 401 is provided with a latch 402 protruding inwards, and the latch 402 abuts against the bottom of the top block 301. Thus, the top block 301 of the slide insert 300 can be inserted into the upper mold driving insert 400, and the slide groove 401 is clamped under the top block 301 through the fixture block 402, so that the top block 301 can only slide out from two sides of the slide groove 401, and the connection relationship between the slide insert 300 and the upper mold driving insert 400 is increased.

In this embodiment, the slide insert 300 is provided with a moving groove 303, and the moving groove 303 is arranged along the moving direction of the slide insert 300; the slide insert 300 is provided with a limiting rod 304 for limiting the upward or downward movement distance of the slide insert 300, and one end of the limiting rod 304 penetrates through the moving groove 303 and abuts against the slide fixing block 500.

The slide insert 300 is limited by the stop rod 304 to move upward, and the slide insert 300 is limited by the stop rod 304 through the moving groove 303 so that the stop rod 304 can pass through the moving groove 303 to limit the upward or downward moving distance of the slide insert 300.

The slide insert 300 has an internal cavity with a bottom opening therein, the bottom opening of the internal cavity being disposed toward the earphone die; the slide insert 300 has an inlet 305 for liquid, and the inlet 305 is connected to the internal cavity.

Like this, effectual assurance product presss from both sides the mouth with advance the gluey point and be convenient for the product to advance gluey in the inside increase in row position, reduce the problem of mouth of a river material extravagant resource, reduce the risk reinforcing product shipment quality of cloak in the sound hole simultaneously, improve the commentaries on classics production rate of mould, reduced the disability rate of mould slider, practiced thrift the development cost and the use of mould and become.

In this embodiment, the slide insert 300 is disposed in an inclined shape, and the slide insert 300 penetrates the slide fixing block 500 from top to bottom; the slide fixing block 500 is provided with a slide cavity for the slide insert 300 to move, and the slide cavity penetrates through the slide fixing block 500; the upper part of the slide cavity is provided with an ejection area for the elastic piece 302 to move; the top of the elastic member 302 is exposed outside the row position fixing block 500.

After the injection molding of the earphone mold is completed in the molding cavity, the upper mold base 100 is taken out upwards, the upper mold base 100 is separated from the pressing of the upper mold driving insert 400, the ejector block 301 is driven by the elastic force of the elastic piece 302 to eject the upper mold driving insert 400 upwards, and the ejector block 301 drives the slide insert 300 to move upwards in an inclined manner, so that the slide insert 300 slides upwards along the inclination inside the slide fixing block 500 until being separated from the back-off area of the earphone mold;

at the moment, the earphone die can be completely ejected, when the die is closed in the next action, the elastic piece 302 plays a role of the slide fixing block 500 and does not move in an ejection area, so that the upper die base 100 is orderly subjected to mechanical action and die closing, the risk of die pressing is avoided, the working efficiency is improved, the production stability of the die is increased, the production efficiency is improved, and the cost is saved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
