[0024] Specifically, by Figure 2-4 The switching mechanism 2 includes a slide bar 201 fixed in the through slot 4, two slide blocks 202 are symmetrically and movably sleeved on the outer side of the slide bar 201, a top plate 2010 is fixedly installed on the top of the slide block 202, two support wheels 2011 are symmetrically arranged at the bottom of the top plate 2010, both of which are located at the top of the base 1, a column 206 is rotatably connected to the top of the top plate 2010, a top block 205 is fixedly installed on the top of the column 206, a U-shaped frame 203 is movably sleeved on the outer side of the column 206, and an arc-shaped clamp is symmetrically and fixedly installed on the outer side of the U-shaped frame 203 209 and square clamp plate 2014, a spring 204 is fixedly connected between the U-shaped frame 203 and the top block 205, the spring 204 is sleeved on the outside of the column 206, two positioning rods 208 are symmetrically fixedly installed on the inner top wall of the U-shaped frame 203, two positioning holes 2015 are symmetrically arranged on the top of the top plate 2010, the bottom ends of the two positioning rods 208 are respectively inserted into the two positioning holes 2015, and a U-shaped pull rod 207 is fixedly installed on the top of the U-shaped frame 203, and the U-shaped pull rod 207 passes through the top block 205 and is movably connected to the top block 205;

[0025] When in use, first pull the U-shaped pull rod 207 upwards to drive the U-shaped frame 203 to move upwards along the column 206. At this time, the spring 204 is compressed until the bottom ends of the two positioning rods 208 are respectively disengaged from the two positioning holes 2015. Then hold the U-shaped pull rod 207 to rotate the U-shaped frame 203 180°. At this time, the positions of the arc clamping plate 209 and the square clamping plate 2014 are swapped. Then the control of the U-shaped pull rod 207 is released. At the same time, the spring 204 is reset to drive the U-shaped frame 203 to move downwards along the column 206 until the bottom ends of the two positioning rods 208 are inserted into the two positioning holes 2015 again, completing the fixation of the U-shaped frame 203 after rotation. Finally, the arc clamping plate 209 and the square clamping plate 2014 are quickly switched to fix casting molds of different shapes.

[0026] Specifically, by Figure 5 It is given that an annular groove 2013 is provided on the inner side of the slider 202, and balls 2012 are installed at equal angles in the annular groove 2013, and each ball 2012 is fitted with the outer wall of the slider 201.

Since multiple balls 2012 are arranged between the sliders 202 and the slide rod 201, direct contact between the slide rod 201 and the slider 202 is avoided, and the friction force on the slider 202 when sliding is reduced. Then drive the two top plates 2010 to move horizontally, and at the same time, the two supporting wheels 2011 at the bottom of the top plate 2010 play a supporting role to ensure the stability of the movement of the top plate 2010. Finally, the two arc-shaped clamping plates 209 or the two square clamping plates 2014 are close to each other to fix casting molds of different shapes.
