Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to the drawings, a detection device for the installation of an iron ring 6 comprises: the mold comprises a mold core 1, a first movable insert 2, a second movable insert 3, a front mold pressing block 4 and a sensor 5. The die core 1 is internally provided with a containing cavity 11, the first movable insert 2 and the second movable insert 3 penetrate through the die core 1, and the first movable insert 2 and the second movable insert 3 are slidably connected with the die core 1. The first removable insert 2 is disposed above the second removable insert 3, the first removable insert 2 is in contact with the front mold block 4, and the second removable insert 3 is in contact with the sensor 5.

The front mould pressing block 4 is arranged above the mould core 1, a groove 41 is arranged at the bottom end of the front mould pressing block 4, and the first movable insert 2 is inserted into the groove 41 of the front mould pressing block 4. The sensor 5 is positioned below the second movable insert 3, and the sensor 5 is a contact sensor 5, and a pressure sensor can be selected. The sensor 5 is electrically connected with the controller, the sensor 5 feeds sensed signals back to the controller, the injection molding machine is controlled to work when the controller receives normal signals fed back by the sensor 5, and otherwise, the injection molding machine stops working.

The diameter size of the groove 41 is matched with the diameter size of the first movable insert 2, when the iron ring 6 is not arranged on the injection molding piece 7, the first movable insert 2 can be inserted into the groove 41 of the front mold pressing block 4 after the front mold pressing block 4 is pressed down, at the moment, the first movable insert 2 cannot move down, the second movable insert 3 cannot contact the sensor 5, and the sensor 5 is in an open state and cannot sense a normal signal.

The first removable insert 2 comprises an insert first end 21 and an insert second end 22, the insert first end 21 being arranged above the insert second end 22, the diameter of the insert first end 21 being smaller than the diameter of the insert second end 22, i.e. the first removable insert 2 is arranged step-wise. The iron ring 6 is sleeved on the first end 21 of the insert, and the bottom surface of the iron ring 6 is contacted with the second end 22 of the insert. In the process of pressing down the front mold pressing block 4, the front mold pressing block 4 continues to be pressed down after contacting the iron ring 6, and the iron ring 6 drives the first movable insert to be pressed down as the bottom surface of the iron ring 6 is contacted with the second end 22 of the insert, and the second movable insert 3 is pushed to move down through the first movable insert until being contacted with the sensor 5.

The first removable insert 2 further comprises an insert third end 23, the insert third end 23 having a diameter greater than the diameter of the insert second end 22. The insert third end 23 is in contact with the second movable insert 3, the contact area between the first movable insert 2 and the second movable insert 3 is increased through the insert third end 23, and the stability is improved in the pressing-down process. When the insert third end 23 contacts the second removable insert 3, the sensor 5 is in an off state and can sense a normal signal.

In order to avoid that the second removable insert 3 damages the sensor 5 during the pressing down process, the detection device further comprises a limiting groove 12, the limiting groove 12 is arranged in the receiving cavity 11, and the diameter of the limiting groove 12 is larger than the diameter of the receiving cavity 11. The insert third end 23 is located in the limiting groove 12, and the height of the insert third end 23 is smaller than that of the limiting groove 12, that is, the insert third end 23 can only move up and down in the limiting groove 12, and the limited distance for the second movable insert 3 to move up and down is avoided, so that the damage to the sensor 5 caused by the overlarge downward pressure to cause the overlarge downward movement distance of the second movable insert 3 is avoided.

The second removable insert 3 comprises an insert upper end 31 and an insert lower end 32, the insert upper end 31 is arranged above the insert lower end 32, the diameter of the insert upper end 31 is larger than that of the insert lower end 32, and the insert upper end 31 is in contact with the first removable insert 2. The contact area between the second removable insert 3 and the first removable insert 2 is increased by the insert upper end 31, and the stability is improved in the pressing-down process.

In actual use, the detection device is arranged after the clamping step and before the injection molding step of the injection molding part 7 machining process.

When detecting the injection molding 7 provided with the iron ring 6: before die assembly, the second movable insert 3 is jacked away from the sensor 5, and the sensor 5 is in an open state; after the die is closed, the second movable insert 3 is pressed down by the iron ring 6, and the sensor 5 is in a closed state; the sensor 5 feeds back the sensed normal signal to the controller, and the injection molding machine produces normally;

when the injection-molded part 7 without the iron ring 6 is detected: before die assembly, the second movable insert 3 is jacked away from the sensor 5, and the sensor 5 is in an open state; after the die is closed, the second movable insert 3 cannot be pressed down due to the fact that the iron ring 6 is not installed, signals are abnormal, and the injection molding machine stops.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
