Abstract

PURPOSE:To shorten the heating time of a tube and consequently contrive to enhance its production efficiency by a method wherein a mold is instantane ously heated by induction heating. CONSTITUTION:Power supply is put to work under the state that a resin tube 10 is pushed against the inner most recess side of the insertion part 23 of a mold 20 by inserting the tip of the resin tube 10 in the insertion part 23. By passing the predetermined alternate current through an induction coil 30, the mold 20 is put in alternating field and generates heat by itself due to eddy current loss and magnetic hysteresis loss, resulting in instantaneously heating the mold up to a temperature, which is not less than the melting point of the resin tube 10. Consequently, the tip of the resin tube 10, which is being pressed in the insertion part 23 of the mold 20, is pushed under softened and molten state in the insertion part 23 and the tip deforms along the shape of the inner bottom face 22 of the insertion part 23, resulting in clogging the tip opening and forming the tip into a hemispherical shape. After the tip of the resin tube is formed into the required shape in the mold, the energizing to the resin coil 30 is stopped for cooling the mold 20. After the solidification of the tip of the resin tube 10, the tube is drawn out of the mold 20.

Next, a method for processing the tip of a resin tube according to the present invention using the mold 20 will be described. The distal end of the resin tube 10 is inserted into the insertion section 23 of the mold 20, and the power source 40 is activated while the resin tube 10 is pressed toward the inner part of the insertion section 23 with a predetermined pressure. The power source 40 can be, for example, a high-frequency power source equipped with a Zyristor inverter, and its output and frequency are determined based on the material and shape of the mold 20 and the induction coil 30 so that the mold 20 can be efficiently inductively heated.
It is determined based on the structure etc., but usually 5Qllz~1
A frequency of 600Hz is used. When a predetermined alternating current is applied to the induction coil 30 by activation of the power source 40, the mold 20 is placed in an alternating magnetic field. As a result, the mold 20 self-heats due to eddy current loss and magnetic hysteresis loss, and instantaneously reaches a temperature equal to or higher than the melting point of the resin tube 10. As a result, the tip of the resin tube 10 being pressed within the insertion section 23 of the mold 20 is pushed into the insertion section 23 in a softened and molten state, as shown in FIGS. 2(a) and 2(b). Therefore, as shown in FIG. 2(C), the tip is deformed to follow the shape of the inner bottom surface 22 of the insertion portion 23, and the tip opening is closed to form a hemispherical shape.

When the tip of the resin tube 10 is molded to a predetermined shape in the mold 20, the current to the induction coil 30 is stopped, and a chiller for cooling at about 5 to 15 degrees Celsius is installed in the cable forming the induction coil 30. distribute it. As a result, the mold 20 is cooled, and the tip of the resin tube 10 inserted into the mold 20 is solidified. After the tip of the resin tube 10 is solidified, it is pulled out of the mold 20, and the supply of the chiller into the cable is also stopped to prepare for the next processing.

When molding the tip of the resin tube IO using such a tip processing method, the inner surface of the mold 20 is also rapidly heated by induction heating, so that the resin tube 10 inserted into the mold 20 is heated. The tip can be softened and melted in an extremely short period of time and molded into a predetermined shape. In this type of molding operation, the heating time of the resin tube IO occupies most of the cycle time, so by shortening this heating time, productivity can be significantly improved. In addition, the mold 2 is passed through a chiller into the cable that forms the induction coil 3°.
By cooling the mold 20, the induction coil 30 is commonly used for heating and cooling the mold 20, and the induction coil 30 itself is also small, making it possible to downsize the device. Moreover, it is also possible to circulate a chiller through both the mold 20 and the induction coil 30 as necessary.
