Referring to fig. 1-4, the present utility model provides the following two technical schemes:

example 1

A die for processing an LED lamp comprises a lower die 1 and a runner 2 arranged in the lower die 1, wherein a specific injection molding structure of an LED lamp housing is shown in China, and the high-precision processing die for producing the LED lamp is disclosed in China (publication number is CN213733246U, and publication date is 2021-07-20). The inside of lower mould 1 is provided with the liftout plate 3 of laminating rather than the inner wall, and the outside parcel of liftout plate 3 has sealing washer 301, through the setting of sealing washer 301, has improved the leakproofness between liftout plate 3 and the lower mould 1, effectively prevents when moulding plastics that the raw materials from leaving from the gap department between liftout plate 3 and the lower mould 1. An ejection structure 4 is arranged in the lower die 1, wherein a connecting piece 5 which drives the ejector plate 3 to move upwards through the ejection structure 4 is arranged on the lower die 1, and the connecting piece 5 is connected with the upper die. After injection molding is completed, the upper die moves upwards, and the ejector structure 4 is pulled through the connecting piece 5, so that the ejector plate 3 is driven to move upwards along the inner wall of the lower die 2, the lamp housing after injection molding is driven to move, and the lamp housing is convenient for staff to take.

Regarding the design scheme of the ejection structure 4, the ejection structure 4 comprises a roller 401 fixedly arranged at the bottom of the ejection plate 3, a wedge block 402 is slidably arranged on the inner bottom wall of the lower die 1, and the roller 401 is attached to the inclined surface of the wedge block 402. A return spring 403 is fixedly arranged on one side of the wedge block 402, and the elastic coefficient of the return spring 403 can be set according to requirements. When the wedge block 402 moves, the roller 401 is pushed to move upwards by the inclined surface of the wedge block, so that the ejector plate 3 is driven to move upwards; by the arrangement of the return spring 403, the return spring 403 can drive the wedge block 402 to restore to the original state when no external force is applied.

As a further technical scheme, an installation block 404 is fixedly arranged in the lower die 1, a connecting spring 406 is fixedly arranged between the ejector plate 3 and the installation block 404, the elastic coefficient of the connecting spring 406 can be set according to requirements, and after the ejector part of the lamp shell after injection molding is ejected, the lamp shell can move downwards to recover to an initial state when no external force acts on the ejector part of the lamp shell, so that the next injection molding is facilitated; the inside of lower mould 1 is fixed to be provided with the guide bar 405 that runs through installation piece 404, and wedge 402 slides and sets up the surface at guide bar 405, and reset spring 403's one end and the fixed setting of installation piece 404, through the setting of guide bar 405, play the guide effect to the direction of movement of wedge 402, improve the stability in its removal in-process simultaneously.

With respect to the design scheme of the connecting piece 5, the connecting piece 5 comprises a connecting rope 501 with one end fixedly connected with the wedge-shaped block 402, and the other end of the connecting rope 501 extends to the top of the lower die 1 and is fixedly connected with the upper die. Thus, after injection molding, the upper mold is moved up, and the connecting rope 501 is pulled, so that the connecting rope 501 pulls the wedge block 402 to perform the working in the horizontal direction, and the wedge block 402 pushes the ejector plate 3 up by the roller 401.

As a further technical solution, a guide tube 502 penetrating through the inside of the flow channel 2 is fixedly provided, and the connection rope 501 penetrates through the guide tube 502. By the arrangement of the guide cylinder 502, water in the runner is effectively prevented from entering the lower die 1.
