2) Arm: equipped with spoon quantitative device, driving device and electrode to prevent the arm from entering the metal solution.

3) Power unit: composed of motor, reducer and driving mechanism.

4) Electrical control: according to the signals from the die-casting machine and other peripheral equipment, send out the action instructions for the soup machine, and automatically control the actions of the soup machine, such as scooping, arm movement, pouring, and standby.

2. Main types:

1) Small size: casting weight 1-3kg, for die casting machine below 350t

2) Medium size: casting weight 3-8kg, for 350t-800t die-casting machine

3) Large size: casting material weight above 8kg, for die casting machine above 800t

4、 Automatic spraying device

The device is a device for automatically spraying mold release agent to the mold.

1. Main components:

1) Nozzle: The nozzle consists of an atomizing device and a nozzle. After the mold release agent is atomized into tiny droplets through a device called atomizer, it is sprayed on the mold surface through a nozzle. The atomizers are either independently manufactured and installed on the valve plate, or integrated with the valve plate. The nozzle is also equipped with a blowing system for blowing off the attachments on the mold surface and drying the release agent on the surface, and some are also equipped with cooling mold and anti ablation spraying systems.

2) Driving mechanism: use air cylinder, servo motor, robot, etc. to drive the nozzle to move from the standby position to the spraying position, and then return to the standby position after the nozzle is completed.

3) Valve box: the input and output equipment that supplies air, water and release agent to the nozzle. The pressure reducing valve, pressure regulating valve, solenoid valve and its pipeline system are arranged in the valve box.

4) Electrical control: according to the signals from the die-casting machine and other peripheral equipment, send out driving, blowing (cleaning), spraying, blowing (drying), returning to the original position and other action commands.

2. Main types:

1) Nozzle: nozzle type nozzle, cartridge type nozzle.

2) Drive mode: cylinder drive, servo motor drive, robot drive.

5、 Automatic pickup device

The device is used to take out the die castings from the die casting machine.

1. Main components:

1) Picking hand: It is composed of a clamping part (claw) and a driving cylinder. The air source from the solenoid valve drives the cylinder to realize the function of taking and placing.

2) Driving mechanism: the cylinder, servo motor, robot, etc. are used to drive the movement of the picking hand.

3) Electrical control: according to the signals from the die-casting machine and other peripheral equipment, send out motion fingers for moving, taking out, placing the workpiece, returning to the original position, etc

Order.

2. Main types:

Drive mode: cylinder drive, servo motor drive, robot drive.

6、 Hydraulic trimming machine

The device is used to cut off the non product parts such as the material handle, material channel and exhaust channel of the die casting. Main components: 1) oil press: (4 columns, single column): general oil press 2) safety protection system: light curtain - automatic shutdown when entering the working area abnormally, safety fence 3) trimming die: designed and manufactured according to different workpieces.

7、 Product conveyor

The device is used to move the removed die castings to the next station.

8、 Shot blasting machine

The device is a device for removing die casting burrs and cleaning die casting surface.

10、 Application of peripheral equipment

According to the statistics on the application of peripheral equipment in Japanese die casting enterprises, it can be seen that the proportion of peripheral equipment in the Japanese die casting industry is relatively high. At present, many die casting enterprises also set up mechanical processing and online monitoring equipment around the die casting machine, from melting, die casting, cleaning, machining to detection. Therefore, the setting and application of peripheral equipment is also an important link to improve the production efficiency and benefit of die casting. (end)
