[0047] By providing the hydraulic telescopic rod body 1, the connecting plate 2, the collar 301, the spring 302, the connecting rod 401, and the pushing ring 402, the utility model has the advantages of axially limiting the lifting die, enabling the die to resist greater axial force in the axial direction, and solving the problem that relying solely on the hydraulic mechanism for lifting will impose a large axial force burden on the hydraulic piston rod of the hydraulic mechanism.

[0048] Embodiment 2: The auxiliary lifting structure of a rubber injection molding machine, see Figure 2 and Figure 3 ;

[0049] Two stoppers 101 are symmetrically and fixedly arranged on the outer wall of the top of the outer tube of the hydraulic telescopic rod body 1.
