[0022] The preferred embodiments of the present invention will be described in detail below with reference to the drawings, and the present invention will be further elaborated.

[0023] First, the novel slider oil cylinder self-locking mechanism according to the embodiment of the present invention will be described in combination with Figures 1 to 6 which is used in a mold and has a wide range of application scenarios.

[0024] As Figures 1 to 6 shown, the novel slider oil cylinder self-locking mechanism according to the embodiment of the present invention includes:

[0025] A slider seat 2, a slider 1 is fixedly connected to the slider seat 2, the slider 1 is arranged in a mold core 8, a first chute 21 and a pair of first guide grooves 22 are arranged on the slider seat 2, a first opening 211 is arranged on one side of the first chute 21, and the pair of first guide grooves 22 are arranged on both sides of the first chute 21;

[0026] A pair of pressing strips 3, the pair of pressing strips 3 are arranged on both sides of the slider seat 2 and are fixedly connected to a moving die template, and a first positioning groove 31 corresponding to the first guide groove 22 is arranged on the pressing strip 3;

[0027] The fixed seat 4 is movably arranged in the first chute 21 and can slide linearly in the first chute 21. A pair of second chutes 41 are arranged on the fixed seat 4, and the pair of second chutes 41 are in a "V" shape.

[0028] A pair of tongue pieces 5, one end of the tongue piece 5 is movably arranged in the second chute 41, and the other end is slidably connected to the first guide groove 22. The tongue piece 5 can slide along the second chute 41 and the first guide groove 22 simultaneously.

[0029] The oil cylinder 6, the output end of the oil cylinder 6 is connected to the fixed seat 4 and can drive the fixed seat 4 to move linearly. The oil cylinder 6 is fixedly connected to the moving die template through the positioning plate 71.

[0030] Further, a second positioning groove 42 is arranged on one side of the second chute 41. The second positioning groove 42 can be coupled with the end of the tongue piece 5 for positioning the tongue piece 5.

[0031] Further, first limiting parts 43 are arranged on both sides of the fixed seat 4, and a pair of second limiting parts are arranged at the first opening 211. The first limiting parts 43 and the second limiting parts interact to prevent the fixed seat 4 from detaching from the first chute 21.

[0032] Further, a third limiting part 51 is arranged at the end of the tongue piece 5. The third limiting part 51 is movably arranged in the second chute 41 and can slide along the second chute 41.

[0033] Further, it further includes: a pressing plate 7, the pressing plate 7 is connected to the slider seat 2 and is used to seal the first chute 21 and a pair of first guide grooves 22.

[0034] Further, one side of the first positioning groove 31 is an inclined surface 32 to facilitate the tongue piece 5 to enter or slide out of the first positioning groove 31.

[0035] Working principle:

[0036] When the mold is opened, the oil cylinder 6 drives the fixed seat 4 to move rightward in the first chute 21, and the tongue piece 5 gradually withdraws from the first positioning groove 31. After the tongue piece 5 completely withdraws from the first positioning groove 31, the first limiting parts 43 on both sides of the fixed seat 4 contact the corresponding second limiting parts, and the fixed seat 4 drives the slider seat 2 to move rightward, and the slider seat 2 drives the slider 1 to demold.

[0037] When the mold is closed, the oil cylinder 6 drives the fixed seat 4 to move leftward, the fixed seat 4 drives the slider seat 2 to move leftward, and the slider seat 2 drives the slider 1 to move leftward to the specified position; the oil cylinder 6 drives the fixed seat 4 to move leftward, and the fixed seat 4 moves leftward in the first chute 21 until the tongue piece 5 reaches and gradually enters the first positioning groove 31. Then, the oil cylinder 6 stops moving, and the slider seat 2 and a pair of pressing strips 3 are locked through a pair of tongue pieces 5.

[0038] As described above, with reference to Figures 1 to 6 the novel slider oil cylinder self-locking mechanism according to the embodiments of the present utility model has been described. It does not require additional oil cylinders and actions, has continuous and time-saving actions, strong compressive capacity, almost no backward movement, small space, stable and reliable structure, and cost savings.
