Problems solved by technology

However, although the inserts in the pipeline are beneficial to enhance heat exchange, they also bring a certain pressure loss, and the fouling of the inserts reduces the heat exchange capacity, which is also an important factor restricting its use.

Embodiment 1

[0022] The specific conditions of the method for improving the heat exchange efficiency between fluid and mold described in this embodiment are as follows:

[0023] First, the fluid that will flow into the cooling / heating channel of the mold is first introduced into the ultrasonic container with exhaust valve; secondly, the ultrasonic transducer is controlled by the ultrasonic generator to apply ultrasonic waves to the fluid in the ultrasonic container, so that the The fluid generates ultrasonic vibration and transmits it to the cooling / heating channel of the mold; finally, the fluid oscillates violently in the cooling / heating channel, greatly improving the heat exchange efficiency between it and the mold, thereby realizing rapid cooling or heating of the mold.

[0024] like figure 1 As shown, in order to realize the device of the above-mentioned method of the present embodiment, it includes an ultrasonic container 2 with an exhaust valve 1, an ultrasonic transducer 3, and an ...

Embodiment 2

[0027] like figure 2 As shown, the difference from Embodiment 1 is that a vibration rod 10 extends into the cavity 9 of the mold in this embodiment, and another ultrasonic transducer 11 is fixed on the vibration rod 10. The energy device 11 is electrically connected with the ultrasonic generator 4, and the ultrasonic generator 4 controls the application of ultrasonic waves to the vibrating rod 10, so that the vibrating rod 10 generates ultrasonic vibration with the same frequency as the fluid flowing through the cooling / heating channel 8 in the mold. , to achieve ultrasonic vibration on the material in the mold cavity, and finally the two ultrasonic waves act on the mold to resonate, further improving the heat exchange efficiency between the fluid and the mold.

Embodiment 3

[0029] like image 3 As shown, what is different from Embodiment 1 is that the fluid inlet of the ultrasonic container 2 in this embodiment is connected to the mold temperature machine 7 through a pipeline, the material to be formed in the cavity 9 of the mold is magnesium alloy, and the mold temperature machine 7 makes the temperature high The mould is heated as the oil at mould temperature flows through the cooling / heating channels 8 in the mould.

Abstract

The invention discloses a method and a device for improving the heat exchange efficiency of a fluid and a die. The method comprises the following steps of first introducing the fluid to flow into a cooling / heating passage of the die into an ultrasonic container with an exhaust valve; then controlling an ultrasonic transducer to apply ultrasonic waves to the fluid in the ultrasonic container to ultrasonically vibrate the fluid in the ultrasonic container and transfer ultrasonic vibration into the cooling / heating passage of the die by using an ultrasonic generator; finally violently oscillating the fluid in the cooling / heating passage to greatly improve the heat exchange efficiency between the fluid and the die, thereby rapidly cooling or heating the die. According to the method and the device, the heat exchange efficiency of the fluid and the die can be remarkably improved to rapidly cool or heat the die, so that the production cycle of a single product can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of mold temperature control, in particular to a method and a device for improving the heat exchange efficiency between fluid and mold. Background technique [0002] The mold is a commonly used tool in industrial production, and the temperature of the mold needs to be controlled in the actual production process. The temperature control of the mold includes heating and cooling the mold. If the melt is to be rapidly solidified and formed, it needs to be rapidly cooled and cooled, which is the cooling system of the mold; and sometimes in order to preheat the mold, the mold is kept at a certain temperature. The mold needs to be heated. In mold temperature control, it is a common method to cool or heat the mold by passing low temperature or high temperature fluid through the channel in the mold. For example, Patent 200620015517.9 describes a water-cooled die-casting punch. The high-temperature aluminum liquid tr...
