Description

Technical Field

[0001] The utility model relates to the field of mold adjustment equipment for high-frequency machines, in particular to a mold height adjustment mechanism for high-frequency machines. Background Art

[0002] High frequency machine is an efficient, fast, low-consumption and environmentally friendly induction heating equipment, mainly used for heating metal and non-metal materials. Figure 1 , which is made of base 1', slider 2', upper template 3', pressing assembly 7', screw 4', screw nut 5' and hand wheel 6'. Figure 1 The die adjustment mechanism of the high-frequency machine is a common mechanism on the market. By rotating the hand wheel, the slider is driven to move up and down relative to the screw nut, thereby adjusting the distance between the upper and lower dies to meet the high-frequency heat sealing of different materials. However, Figure 1 The downward pressure component in the machine acts directly on the handwheel, which brings certain safety risks to the operation of the handwheel, and makes the overall height of the high-frequency machine higher, which is not conducive to transportation. At the same time, the process of operating the handwheel is also very inconvenient. Utility Model Content
