Abstract

A mold for ultrathin polyethylene tableware, comprising a mold body (1). During production, when logo replacement is required, a rotatable block (23) is rotated so that the rotatable block (23) is removed, and then a cylinder (26) is rotated so that the cylinder (26) is removed for replacement. The replaced cylinder (26) is inserted into a first mold bump (16), and then the rotatable block (23) is snap-fitted into the cylinder (26) and then tightened. There is no need to replace the mold on the whole, and the logo or pattern replacement cost of an enterprise is reduced. In addition, when an upper template (12) squeezes a lower template (5), the generated vibration energy is transferred to a first damping spring (7) and a second damping spring (11). Buffering and absorbing the collision energy generated by the upper template (12) and the lower template (5) by means of the first damping spring (7) and the second damping spring (11) can effectively protect the mold, and improve the service life of the mold.
