[0025] It should be noted here that: by setting the driving mechanism, it is convenient to drive the four L-shaped clamping plates 205 to move closer to or away from the mold.

[0026] Two guide rods 4 are fixedly connected between two opposite side walls of the driving chamber 301. The two guide rods 4 are symmetrically arranged about the push rod motor 304. The driving plate 302 slides on the side walls of the two guide rods 4.

[0027] It should be noted here that the guide rod 4 is provided to provide a guiding and limiting function for the movement of the driving plate 302 .

[0028] The limiting mechanism includes a plurality of mounting holes 501 formed on the side wall of the sliding plate 203, each mounting hole 501 being slidably connected to a limiting rod 502, a limiting hole 504 being formed on the side wall of the sliding frame 202, each limiting rod 502 being matched with the limiting hole 504, and each limiting rod 502 having a rounded corner 503 at one end away from the bottom wall of the mounting hole 501, and each rounded corner 503 sliding on the inner wall of the sliding frame 202;

[0029] It should be noted here that: by setting the limiting mechanism, the height of the L-shaped clamping plate 205 is limited, thereby ensuring the position stability of the L-shaped clamping plate 205 during use.

[0032] The side walls of each fillet 503 are polished;

[0033] It should be noted here that: by polishing the fillet 503, the surface roughness of the fillet 503 is increased and the friction force is reduced.

[0034] Working principle: When the mold needs to be clamped for welding, the mold is first placed on the clamp table 101, and then the L-shaped clamp 205 is adjusted accordingly according to the height of the mold. When the height of the L-shaped clamp 205 is adjusted, the sliding plate 203 is pulled or pushed to move in the sliding frame 202. During the movement of the sliding plate 203 in the sliding frame 202, the limit rod 502 is driven to move synchronously. When the side wall of the limit rod 502 abuts against the inner wall of the sliding frame 202, the fillet 503 is Under the interaction force of the push assembly and the guiding action of the push assembly, the push limit rod 502 is retracted into the mounting hole 501. When the L-shaped clamping plate 205 is adjusted to the center position of the mold height, the pushing or pulling of the sliding plate 203 can be stopped. At this time, under the elastic action of the push assembly, the push limit rod 502 is pushed into the limit hole 504, so that under the limiting action of the limit rod 502, the height of the L-shaped clamping plate 205 is limited, ensuring the position stability of the L-shaped clamping plate 205 during use;

[0035] After the height adjustment of the four L-shaped clamps 205 is completed, the push rod motor 304 is started to drive the driving plate 302 to move downward. During the downward movement of the driving plate 302, the driving rod 303 will be driven to rotate. During the rotation of the driving rod 303, under the action of force and the guiding action of the inclined groove 201, the four L-shaped clamps 205 will be driven to move close to the corner of the mold. When the four L-shaped clamps 205 are against the corner of the mold, the push rod motor 304 can be stopped. At this time, under the tight action of the four L-shaped clamps 205, the clamping and limiting of the mold is achieved. The operation is simple and the implementation is convenient. Moreover, since only the four corners of the mold are against each other, the blocking area of ​​the mold side wall is reduced, further ensuring the welding operation of the mold.
