In order to make the technical means, the creation features, the achievement objects and the functions of the invention easy to understand, the following embodiments are combined with the accompanying drawings to specifically describe the composition, the structure, the connection of the components and the position relationship, the working principle and the using method of the insert placing system of the invention.
FIG. 1 is a schematic diagram of an insert placement system in an embodiment of the invention.
As shown in fig. 1, the insert placing system 1000 includes an insert placing device 100 and a control device 200.
The placing apparatus 100 for inserting a ferrous metal insert into an injection molded part injected from an injection mold of an injection molding machine includes a placing mold 10, a transfer unit 20, an electromagnet 30, an inductor 40, and a disassembling robot 50.
Placing the mold 10, installing on injection mold A for place the embedding piece, the tip is provided with the block structure down, is used for detachable to install on injection mold A's the reservation runner. The mold 10 is shaped to match the insert to accommodate the insert C.
The transfer unit 20 for aligning the inserts C in the correct direction and transferring them one by one to the placing mold includes a transfer passage 21 and a screw vibrator 22. The inserts C are conveyed one by one under the vibration of the auger vibrator 22 to the opening of the placing mold via the conveying passage 21, and are dropped one by one into the placing mold 10.
And the electromagnet 30 is arranged on the side wall of the placing die 10 and is used for tidying the embedded parts falling into the placing die 10. In this embodiment, in order to enhance the effect of the magnetic force and make the structure simple, the magnetic core of the electromagnet 30 in this embodiment is the placing mold 10, for this reason, the placing mold is made of a soft magnetic material, and the outer wall of the placing mold 10 is sleeved with the electromagnetic coil, so that the placing mold sleeved with the coil is the electromagnet 30.
And a sensor 40 disposed on the placing mold, wherein in the embodiment, as shown in fig. 1, a sensing head of the sensor is disposed at a right upper opening of the placing mold for sensing the insert, and in the embodiment, a light sensor is used.

At the same time, the control device 200 controls the action of the spiral vibrator 22 so that the inserts C are conveyed one by one under the vibration of the spiral vibrator 22 to the opening of the placing mold via the conveying passage 21 and fall one by one into the placing mold 10.
When the insert falls and is sensed by the sensor 40 and sends a sensing signal to the control device 200, the control device 200 sends a control current after a predetermined time to control the electromagnet to be electrified to generate an attraction force to the insert (the duration of the control current is 2-30 seconds, and the predetermined time refers to 0.5-2.5 seconds after the injection molding machine starts to eject the injection molding blank), so that the attraction force can accurately position the insert on the one hand, and firmly fix the insert in the mold without moving on the other hand, and the embedding position of the insert cannot be influenced by the movement of the injection molding blank during injection molding
The two time parameters can be set in the control device.
After the injection molding is completed, the injection molding machine C sends a completion signal to the control device, the control device 200 controls the disassembling and assembling mechanical arm 50 to disassemble the placing mold 10, then the injection mold opens the mold, the injection molding part embedded with the embedded part C is discharged, the mold is closed, and the next injection molding preparation process is carried out.
Effects and effects of the embodiments
According to the insert placing system related to the embodiment, the placing mold can be installed on the injection mold and used for placing the insert, the electromagnet is used for attracting and fixing the insert placed in the injection mold and the placing mold, when the insert falls and is sensed by the sensor and sends a sensing signal to the control device, the control device sends control current to control the electromagnet to be electrified to generate attraction force on the insert, the attraction force enables the insert to be accurately positioned on the one hand, and on the other hand, the insert is firmly fixed in the mold and cannot move, and therefore the embedding position of the insert cannot be influenced by the movement of an injection molding blank during injection molding. Therefore, the insert placing system can be used for embedding the metal insert only by reserving or designing a connecting port on the existing injection mold, so that the cost is saved, the design is simplified, and the design and manufacturing time of the mold is shortened.
Because the mold is placed in a shape matching the insert to accommodate the insert, this arrangement allows for better positioning of the insert and more accurate coupling of the insert to the injection molded part during injection molding.
Further, because set up the coil on placing the mould to make and place the mould and become the electro-magnet, make simple structure, colleague magnetic force is also stronger.
Furthermore, because the placing mould is detachably mounted, and meanwhile, the placing mould is mounted and dismounted through the dismounting manipulator, the automatic operation is realized.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
