[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. It has the characteristics of miniaturization, digitization, intelligence, multi-function, systematization and networking. It is the primary link in realizing automatic detection and automatic control.

[0003] With the development of society, the application of sensors has gradually increased. When the sensor is injection molded, the existing sleeve, that is, the insert, is fixed to the mold insert by a ball mechanical fixation. If the sleeve is not firmly inserted, it will cause the risk of falling when the workbench of the molding machine rotates. In addition, after the sensor is injection molded, when the finished product is released from the mold, the ball pressed on the inside of the sleeve may cause strain to the inside of the sleeve. Therefore, those skilled in the art provide a sensor insert that is not easy to fall off to solve the problems raised in the above background technology. Utility Model Content

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a sensor insert that is not easy to fall off. When the sleeve moves into the mold insert, it drives the moving block to move toward the square groove, and then drives the two clamping blocks to move. Because the lengths of the two sliding blocks are greater than the two fixed blocks, when the two clamping blocks move toward the direction of the square groove, they also drive the two sliding blocks to move respectively. Under the rebound action of the support block and the two third springs, the moving block drives the two second springs and the two clamping blocks to move in the opposite direction, and then the two clamping blocks are respectively clamped on one side of the two fixed blocks. Because the upper end of the sleeve is made of metal, the sleeve can be fixed in the mold insert by strong magnetic attraction at the same time.

[0033] It can be seen that the first spring 201 is fixedly arranged at the middle position of one side of the sleeve 1, the moving block 202 is fixedly arranged at one side of the first spring 201, the two second springs 203 are respectively fixedly arranged at the middle position of the front and rear ends of the moving block 202, and the two clamping blocks 204 are respectively fixedly arranged at one end of the two second springs 203, and a square groove 11 is opened at the middle position of the inner wall of one side of the mold insert 3, and a sliding groove 10 is opened at the inner wall position of the front and rear ends of the inner wall of one side of the square groove 11;

[0034] According to the invention, two third springs 6 are fixedly provided on the inner wall of one side of the square groove 11, a support block 5 is fixedly provided on one side of the two third springs 6, a slide bar 8 is fixedly provided on the inner wall of one side of the two slide grooves 10 near the middle position, a fixed block 7 is penetrated through the outer periphery of the two slide bars 8 near one side, and a slide block 9 is slidably provided on the outer periphery of the two slide bars 8 near the other side. When the sleeve 1 moves into the mold insert 3, it drives the moving block 202 to move toward the square groove 11, and then drives the two clamping blocks 204 to move. Because the lengths of the two sliding blocks 9 are greater than the two fixed blocks 7, when the two clamping blocks 204 move toward the direction of the square groove 11, they also drive the two sliding blocks 9 to move respectively.

[0035] It can be known that under the rebound action of the support block 5 and the two third springs 6, the movable block 202 drives the two second springs 203 and the two clamping blocks 204 to move in the opposite direction, so that the two clamping blocks 204 are respectively clamped on one side of the two fixed blocks 7.

When the sleeve 1 needs to leave the mold insert 3, the sleeve 1 is squeezed in the direction of the square groove 11, so that the sleeve 1 drives the third spring 6 and the moving block 202 to squeeze the support block 5, and then drives the two clamping blocks 204 to move to one end of the two sliding blocks 9 respectively, and then pulls the sleeve 1 in the opposite direction, so that the two clamping blocks 204 respectively drive the two sliding blocks 9 to move until the two sliding blocks 9 are respectively combined with the two fixed blocks 7, and then the two clamping blocks 204 slide out of the square groove 11, and the sleeve 1 can be taken out.
