Abstract

PURPOSE:To remove casting sand stuck on a casting with the min, energy input so as to reduce noise and dust produced by deciding a frequency with automatically detecting the max resonance point of a vibrating mold and imparting vibration energy on a mold. CONSTITUTION:Vibrators 1 of one or plural are integrated in a stool and is vibrated by remote operation through wireless or wire, a mold 4 consisting of sand casting is placed on the stool. The mold 4 is vibrated with applying vibration to the vibrator 1, a resonance point of the mold 4 is detected by a sensor 7, deciding the power frequency and vibration pattern by a control system 8, the result is feeded back to the vibrator 1 through a power amplifier 9. Thus, the mold 4 is taken out with the least vibration and is parted efficiently in short time with reducing dust, noise produced, further the stool integrated with the vibrator 1 is used as a molding plate pattern draw is executed at any place and time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for vibrating a cast product by vibrating the mold to remove the cast product from the mold.

[0002]

2. Description of the Related Art A conventional method for removing a casting from a casting mold includes blasting using impact force, chipping, chemical treatment using chemicals, and fixed vibration removal using simple vibration. and so on.

[0003]

Among the conventional die-cutting methods, blasting and chipping have no effect on the narrowed portion, and wear, damage to the surface layer, and also near dust, vibration and noise sources, depending on the case. There was a problem that I had to hold it in my hand and work. Further, in the chemical treatment, it is indispensable to handle the poisonous substance, and there are problems such as equipment, post-treatment and waste liquid treatment. Furthermore, in the vibrating die-cutting method using simple vibration, a large fixed device is required, deformation of the flask and product may occur, and noise and dust are generated significantly. There were problems such as doubts about the effect.

The present invention was developed to address such problems, and an object thereof is to vibrate the mold by utilizing the maximum resonance point of the mold.

[0005]

The structure of the present invention for achieving the above-mentioned object is to vibrate the mold, and vibrates the mold in a vibrating die-cutting method for a cast product, wherein the cast product is taken out from the mold. It is characterized in that the highest resonance point of the mold is automatically detected to determine the frequency, and vibration energy of the frequency is applied to the mold.

[0006]

According to the present invention, since the casting product, the foundry sand, and the mold composed of the casting frame and the like are added with the vibrational energy of the resonance frequency by the above means, the foundry sand adhering to the periphery of the casting product is minimized. Since it can be removed by inputting energy, the amount of noise and dust generated can be reduced, and the casting surface of the cast product is not damaged, and since vibration energy is added by remote control, workers vibrate. Not exposed to dust, noise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings, in which reference numeral 1 represents a vibrator, and one or more vibrators 1 are incorporated in a surface plate 2 as shown in FIG. 2 is operated by remote control, and a mold 4 composed of a sand casting 3 is placed on the surface plate 2 as shown in FIG.

FIG. 3 shows another embodiment, in which a container 6 containing a mold 4 made of a sand casting 3 and a precision casting 5 is placed on the plate 2. Then, as shown in the system flow chart of FIG. 4, the vibration of the vibrator 1 causes the mold 4 to vibrate, the resonance point of the mold 4 is detected by the sensor 7, and its power frequency and vibration pattern are controlled by the control system 8. And is fed back to the vibrator 1 via the power amplifier 9.

[0009]

As described above, according to the present invention, the highest resonance point of the vibrating mold is automatically detected to determine the frequency,
Since the vibration energy of that frequency is applied to the mold, the mold can be taken out by the minimum necessary vibration, the amount of dust and noise generated can be reduced, and the mold can be removed efficiently in a short time. The vibrator can be incorporated into the board and used as it is as a board plate at the time of molding, and at the same time, it is possible to perform die-cutting at an arbitrary place and time.
