DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 to Figure 4 As shown, a quick locking mechanism for an injection mold comprises a mold fixed mold 1, a mold movable mold 3 is arranged on one side of the mold fixed mold 1, a guide hole 2 is opened on the mold fixed mold 1, a guide mechanism 4 is arranged between the mold fixed mold 1 and the mold movable mold 3, the guide mechanism 4 comprises a guide rod 401, a limiting groove 402, a limiting protrusion 403, a limiting screw 404 and a limiting nut 405, a limiting mechanism 5 is arranged in the mold fixed mold 1, the limiting mechanism 5 comprises an electromagnet 501, an iron pillar 502, a limiting spring 503, a spring seat 504 and a limiting block 505, and the guide rod 401 is connected to the mold fixed mold 1 through the guide hole 2.

[0024] A guide mechanism 4 is provided between the mold fixed die 1 and the mold movable die 3, and the guide mechanism 4 includes a guide rod 401, a limiting slot 402, a limiting protrusion 403, a limiting screw 404 and a limiting nut 405. The guide rod 401 is fixedly installed on the mold movable die 3, and a limiting slot 402 is provided on the guide rod 401. Limiting protrusions 403 are fixedly installed on both sides of the guide rod 401. A limiting screw 404 is fixedly installed at one end of the guide rod 401, and a limiting nut 405 is provided on the limiting screw 404. The mold fixed die 1 and the mold movable die 3 can be connected together through the guide rod 401, and the limiting nut 405 can be loosened during use. After the limiting nut 405 is loosened, the guide rod 401 can be separated from the mold movable die 3, thereby separating the mold fixed die 1 and the mold movable die 3 when the electromagnet 501 fails.

[0025] A limiting mechanism 5 is provided in the mold fixed die 1, and the limiting mechanism 5 includes an electromagnet 501, an iron pillar 502, a limiting spring 503, a spring seat 504 and a limiting block 505. The iron pillar 502 is movably installed in the mold fixed die 1, and a spring seat 504 is fixedly installed on the iron pillar 502. A limiting spring 503 is sleeved on the iron pillar 502. A limiting block 505 is fixedly installed at the lower end of the iron pillar 502, and an electromagnet 501 is provided above the iron pillar 502. After the mold movable die 3 moves to a suitable position, the limiting spring 503 will push the iron pillar 502 on the spring seat 504 to move downward, so that the limiting block 505 is stuck in the limiting slot 402, thereby limiting the movement of the guide rod 401, so that the mold fixed die 1 and the mold movable die 3 are locked, and the electromagnet 501 can be started at the same time. After the electromagnet 501 is started, it will adsorb the iron pillar 502.

[0026] It should be noted that the utility model is a quick clamping mechanism for an injection mold. In actual use, the mold fixed mold 3 can be moved first. Since mounting grooves are provided at the edges of both sides of the mold movable mold 3, the guide rods 401 are installed at the edges of both sides of the mold movable mold 3 through the mounting grooves. The limiting nuts 405 are connected to one end of the guide rods 401 through the limiting screws 404. The guide rods 401 are limited to the mold movable mold 3 through the limiting nuts 405. The limiting blocks 505 are embedded in the guide rods 401 through the limiting grooves 402. Therefore, during use, the mold movable mold 3 can move left and right, so that the guide rods 401 can move in the guide holes 2. At the same time, since a movable groove is provided in the mold fixed mold 1, the iron pillars 502 are movably installed in the mold through the movable grooves. The inner wall of the fixed mold 1, one end of the limit spring 503 is connected to the spring seat 504, and the other end of the limit spring 503 is connected to the upper end of the movable groove. The electromagnet 501 is aligned with the iron pillar 502 up and down, and the electromagnet 501 is located at the upper end of the movable groove. Therefore, after the mold movable mold 1 moves to a suitable position, the limit spring 503 will push the iron pillar 502 on the spring seat 504 to move downward, so that the limit block 505 is stuck in the limit slot 402, thereby limiting the movement of the guide rod 401, so that the mold fixed mold 1 and the mold movable mold 3 are locked, and the electromagnet 501 can be started at the same time. After starting the electromagnet 501, it will absorb the iron pillar 502, so that the limit block 505 is separated from the limit slot 402 and quickly released.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
