The movable worktable 3 is provided with a support plate 5, and the support plate 5 has a plurality of sliding grooves 6 arranged in a cross shape. Each sliding groove 6 is slidably connected to a slider 7, and each slider 7 is threadedly connected to a first bolt 8. Each first bolt 8 is rotatably connected to a side baffle 9 on its threaded section. The nut end of the first bolt 8 is arranged above the side baffle 9. The dispensing mold 4 is installed above the support plate 5 and is located between the plurality of side baffles 9.

[0023] With the support plate 5, as well as the slide groove 6, slider 7, first bolt 8 and side baffle 9, the dispensing mold 4 can be fixed on the support plate 5, effectively avoiding direct contact between the dispensing mold 4 and the moving worktable 3. Furthermore, the movable locking effect of the slider 7 in the slide groove 6 allows dispensing molds 4 of different specifications to be installed and fixed on the support plate 5, making installation convenient while avoiding damage to the moving worktable 3.

[0024] Specifically, in this embodiment, two L-shaped rods 10 are connected to the bottom end of the pallet 5. The two L-shaped rods 10 are arranged symmetrically to each other.
