[0002] In remote control production, welding is a common processing method used to firmly connect different parts or materials together. Welding is usually done by heating the contact surfaces of two parts or materials to partially melt and bond them together.

[0003] The lower die of the existing hot pressing and welding equipment for remote control shells and panels is fixed on the working platform by a fixed pressure plate, just below the hot pressing die; the hot pressing die is fixed on the heating plate, and the heating plate is fixed on the connecting plate at the end of the cylinder shaft. Each time the mold is changed and the required hot pressing and welding position is aligned, it is achieved by moving the lower die position. Each time, the lower die position needs to be fine-tuned repeatedly to align with the welding position. After the position is adjusted, the fixed pressure plate is locked.

[0004] In the traditional structure, the lower mold is fixed during the entire hot pressing welding process, and the hot pressing module is driven up and down by a cylinder. In addition, the space between the lower mold and the hot pressing mold is limited. When picking up and placing products, workers need to put their hands into the hot pressing range and they will be very careful. If they are not careful, their hands can easily be burned by the high temperature of the hot pressing mold. In addition, the distance between the mold and the product is far, which affects work efficiency. Utility Model Content

Those skilled in the art know that the bolts and the height adjustment plate 33 should be movably connected, and two nuts are threadedly connected to the outer side of each bolt. By adjusting the threaded position of the two nuts, the position of the height adjustment plate 33 can be adjusted and fixed.

[0032] In addition, in the utility model, at least one guide shaft 23 is fixedly installed on the top of the connecting plate 22, and a linear bearing 24 is arranged on the top of the frame 1, and the guide shaft 23 is plugged into the linear bearing 24. Furthermore, in this embodiment, in order to improve the movement stability of the above-mentioned connecting plate 22, guide shafts 23 are installed at the four corners of the top of the connecting plate 22. Of course, there should be four linear bearings 24 on the frame 1 symmetrically arranged, and the four guide shafts 23 are movably plugged into the four linear bearings 24 to achieve smooth guiding of the connecting plate 22.
