Claims (1)

[Claims for Utility Model Registration] 1. An upper surface plate 2 supported by the main body frame 1 that moves up and down to serve as an upper electrode, and a lower surface plate that is movable from directly below the upper surface plate to the outside of the main body frame and serves as a lower electrode. In the high-frequency welder, the workpiece is placed on the lower surface plate 4, the upper surface is pressed by a mold on which a welding pattern is formed, and welded by high-frequency dielectric heating, one end is connected to the main body frame. A support arm device 6 supported on the body frame and rotatable on the outside of the main body frame is provided, and a first mold 7 is detachably supported on the support arm device, and a first mold 7 is mounted on the lower surface plate 4 pulled out from the main body frame. The first mold 7 can be placed and removed freely, and a second mold 26 is installed below the upper surface plate 2 in the main body frame so that it can move in and out directly below the upper surface plate by horizontal movement. A mold changing device in a high frequency welder characterized by the following: 2. Lower surface plates 4, 4 are disposed on both front and back sides of the main body frame 1, respectively, and are movable directly below the upper surface plate, and support arm devices 6 each support a mold on both front and back sides of the main body frame. 6. The mold changing device for a high frequency welder according to claim 1, further comprising: 6. 3 The support arm device 6 is provided with a support rod 8 that moves forward and backward in the direction of the lower surface plate 4 pulled out from the main body frame 1 in the lower position of rotation, and the support rod is inserted into the hole 9 drilled in the first mold 7. 3. The metal mold in the high frequency welder according to claim 1 or 2, wherein the metal mold 7 is loosely inserted to support the mold, and the support arm device 6 can be stopped at a position where the mold 7 is slightly apart from the lower surface plate 4. Type change device.
