1. A bearing between planar guide surfaces of a guide rail pillar of a mold box and a mold plate of the mold box, the mold plate being moveably arranged on the guide rail pillar, the guide rail pillar having a longitudinal axis, the bearing comprising:
a bearing element having a main body part with a first end and a second end and defining a through-going opening for receiving said guide rail pillar, the through-going opening extending from said first end to said second end through said main body part, and the through-going opening having one inner surface for each planar guide surface of the guide rail pillar,
wherein, for at least one of the planar guide surfaces of the guide rail pillar, the bearing element comprises a first planar bearing surface and a second planar bearing surface arranged in a common plane and parallel to at least one of the planar guide surfaces, and spaced apart directionally towards the longitudinal axis, the first planar bearing surface arranged at the first end and the second planar bearing surface arranged at the second end of the bearing element,
wherein the first and second planar bearing surfaces are elevated above the corresponding inner surface of the through-going opening,
wherein the first and second planar bearing surfaces are separated by an intermediary surface portion being retracted from the common plane of the two planar bearing surfaces, and
wherein, below each of the first and second planar bearing surfaces, a cavity is formed in the bearing element, such that a portion of the bearing element is provided with a resilience relative to the main body part of the bearing element.
