Do you know what is the Ultrasnic water spout vibration and fall？

Ultrasnic water spout vibration and fall is a device that uses ultrasonic technology to remove the sprue of plastic products. The process of separating the injection mold product from its runner by applying ultrasonic energy to the limited area of ​​the sprue (runner opening) of the injection mold product is called dewatering. When the ultrasonic energy activates the sprue with a very small cross-section, the high temperature activates the friction between the plastic molecules, and the stress here increases, causing the injection molded product and the runner to break at the sprue.

The Ultrasnic water spout vibration and fall Equipment uses high-frequency vibrating ultrasonic energy to convert electrical energy into mechanical energy through a transducer, so that the tool head (commonly known as an ultrasonic welding head) generates high-frequency vibration. When the ultrasonic welding head contacts the sprue of the plastic product, this high-frequency vibration causes violent friction of the plastic molecules at the sprue, thereby rapidly heating up to the melting point of the plastic. Under the combined action of high temperature and pressure, the connecting part between the sprue and the product body is melted and separated, achieving the purpose of removing the sprue.

Equipment composition
Ultrasonic generator: Generates high-frequency electrical signals to provide energy source for the entire equipment. Its power and frequency can be adjusted according to different processing requirements.
Transducer: Converts the high-frequency electrical signal generated by the ultrasonic generator into mechanical vibration. It is usually made of materials such as piezoelectric ceramics and has high energy conversion efficiency.
Ultrasonic welding head: Also known as the tool head, it is the part that directly contacts the plastic product. Its shape and size are customized according to different product shapes and sprue positions. It can transmit the mechanical vibration generated by the transducer to the sprue part to achieve precise dewatering operation.
Fixture: Used to fix the plastic product to be processed, ensure the stability of the product position during the dewatering process, and ensure processing accuracy and quality. The fixture is usually specially designed according to the shape and size of the product to achieve fast clamping and positioning.

Principle:
Put the plastic workpiece taken out of the injection molding machine into the fixed model, start the switch button, press the start switch, and the ultrasonic welding head descends and presses the plastic workpiece for high-frequency vibration. When the sprue with a small cross-section is activated by ultrasonic energy, the friction between the plastic molecules is activated due to the high temperature. At this time, the stress increases, resulting in the fracture of the flow channel at the injection molded product and the sprue. The surface of the nozzle workpiece after cutting is flat and smooth, without whitening, and it is as beautiful as direct injection molding, which saves a lot of labor and improves production efficiency.

There are two types of ultrasonic nozzle cutting machines, one is vertical, similar to the structure of the welding head moving up and down, and the other is horizontal, contact structure, which does not require too much pressure; the horizontal structure is convenient for cooperation with the manipulator of the injection molding machine to achieve automatic operation.
Ultrasonic nozzle cutting is particularly suitable for hard thermoplastics such as polystyrene, nylon, acrylonitrile-butadiene-styrene copolymer, polycarbonate, acrylonitrile-butadiene-styrene copolymer, polymethyl methacrylate, etc. The cross-sectional consistency of soft thermoplastics after water removal is poor.

Advantages of ultrasonic nozzle cutting
High precision: It can accurately remove the nozzle without damaging the body of the plastic product, ensuring the appearance quality and dimensional accuracy of the product. The traditional method of mechanical cutting or manual trimming of nozzles is prone to problems such as uneven cutting and large dimensional deviation, especially for some plastic products with complex shapes and high precision requirements, it is difficult to ensure the quality of nozzle removal.

High efficiency: The ultrasonic dewatering process is fast and can complete the dewatering of a large number of products in a short time, thus improving production efficiency. Traditional dewatering methods, such as manual trimming, are slow, and long hours of work can easily lead to worker fatigue, affecting production efficiency.

Environmental protection and energy saving: Compared with traditional dewatering methods such as mechanical cutting or chemical dissolution, ultrasonic dewatering equipment does not require the use of tools or chemical solvents, which reduces tool wear and chemical pollution, and also reduces energy consumption.

High degree of automation: It can be combined with automated production lines to achieve a series of operations such as automatic loading, positioning, dewatering and unloading, reduce manual intervention, and improve production stability and consistency.
Application areas: It is widely used in the plastic processing industry, such as the production of plastic products in the fields of automotive parts, electronic appliances, medical devices, and daily necessities. For example, plastic buckles for automotive interior parts, edge dewatering of electronic housings, and plastic accessories for medical devices can all be processed efficiently and accurately using ultrasonic dewatering equipment.
