にするものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for a synthetic resin mold and a cleaning method using the cleaning apparatus. More specifically, the present invention relates to a method for cleaning resin molds and gas burns on a resin molding surface of a mold. The kimono can be surely removed in a short time.

て洗浄し、上記付着物を除去しなければならない。2. Description of the Related Art In a synthetic resin mold, an adhered substance such as a resin residue or a burn mark due to gas adheres to an inner surface of the mold according to a molding amount of a resin product. The deposits cause inconveniences such as poor mold release of a product to be molded later, leading to molding failure. Therefore, the synthetic resin mold must be periodically removed and washed to remove the deposits.

型構成部品を磨くのに、約１５分の時間を要するため作
業性が悪い問題もある。Heretofore, in this type of cleaning work, a mold component disassembled into a mold is immersed in kerosene for half a day, and then brushed by an operator. However, this polishing operation is very troublesome because the mold is expensive and must be carefully done so as not to damage it. In addition, it takes about 15 minutes to polish one mold component, so that there is a problem that workability is poor.

法がある。[0004] On the other hand, conventionally, an electrode plate connected to an anode (+) and a mold connected to an anode (-) are immersed in a cleaning tank containing an electrolytic cleaning solution, and the above-mentioned electrolytic solution is immersed. By energizing through the cleaning liquid, a bubble-like electrolytic gas is generated from the inside of the electrode plate and the mold, and while the electrolytic cleaning liquid is being stirred by the electrolytic gas, the adhered substance is lifted up from the mold to form the mold. There is an electrolytic cleaning method for performing cleaning.

しまう場合がある。However, in the cleaning method using the electrolytic method, it is impossible to remove the deposit unless the part to be cleaned of the mold is in a position that looks linear with the electrode plate. For example, in the case of a concave groove having a depth of 3 mm and a width of 2 mm, the bottom surface of the groove, that is, a shaded portion cannot be cleaned. In addition, since the deposits hinder the current to be supplied, electrolytic gas is hardly generated, and thus,
In addition to delaying the operation time, if the operation time is too long, there is a problem that alkali burning occurs on the surface of the mold. Further, the efficiency of stirring the electrolytic cleaning solution due to generation of decomposition gas is poor, and the removed deposits may adhere to the mold again.

And separated by the nonwoven fabric. That is, by supplying only the washed electrolytic cleaning solution into the chemical solution tank, it is possible to reliably prevent the adhered substance once removed from adhering to the object to be cleaned again. In addition, since the electrolytic cleaning liquid is cleaned by the nonwoven fabric, the life of the electrolytic cleaning liquid can be extended.

る。Further, as described above, in the cleaning apparatus of the present invention, the vibrator for transmitting ultrasonic waves to vibrate the cleaning liquid is provided on the bottom of the chemical solution tank containing the electrolytic cleaning liquid, and the ultrasonic cleaning method of the cleaning object. Cleaning is performed. The object to be cleaned is detachably mounted in a chemical solution tank and housed in a basket connected to a cathode so that a cathode current flows through the basket. In addition, a shaft portion connected to the anode and a rocking shaft consisting of a bent portion whose lower end is continuously immersed in the electrolytic cleaning liquid are provided, and a rod-shaped electrode is provided at the tip of the bent portion, through the electrolytic cleaning solution. It is made to be able to carry out electrolytic cleaning by supplying electricity. Further, since the oscillating shaft is made to oscillate in the circumferential direction of the shaft portion by the driving means, the electrode oscillates through the oscillating shaft to stir the electrolytic cleaning liquid and to make the shape complicated. Even in an object to be cleaned, it is possible to eliminate a shadowed portion, and to perform an efficient removing operation. Further, a discharge pipe is provided on the liquid level of the electrolytic cleaning liquid in the chemical tank to discharge the overflowing electrolytic cleaning liquid in the chemical tank to the purification tank, and the electrolytic cleaning liquid is washed by the filter cloth in the purification tank. The electrolytic cleaning liquid in the chemical solution tank is discharged from the supply pipe through the supply pipe so as to convectively flow. Therefore, the cleaning apparatus having the above configuration removes the extraneous matter from the outside of the object to be cleaned by the ultrasonic cleaning method, and lifts the extraneous matter from the inside of the object to be cleaned by the electrolytic cleaning method. The deposits can be surely separated and removed by the convection of the electrolytic cleaning solution by the circulation pump. Further, since the deposits removed by the purification tank are separated from the electrolytic cleaning liquid, the removed deposits do not adhere to the cleaning target again, and the work of removing the deposits can be performed efficiently. In addition, since the adhered substance is broken down from the outside of the object to be cleaned by the ultrasonic cleaning method, the energizing action performed by the electrolytic method can be reliably performed, and the adhered substance can be reliably removed in a short time. Can be done.
