Device for ejecting a mould, comprising a chain with sliding links and an adjustment shim

An ejection device for a mould for making a moulded article in a moulding cavity for enabling ejection of the moulded article from the moulding cavity, said device comprising:

• a pushing device that can be moved in translation along a first axis between a retracted position and an ejection position,
• at least one ejection element that can move in translation along a second axis, different from the first axis, between a retracted position and an ejection position,
• at least one transfer device connecting the pushing device and the ejection element, said transfer device being arranged to move the ejection element along the second axis between its retracted position and its ejection position when the pushing device is moved along the first axis between its retracted position and its ejection position, the transfer device comprising a transmission chain comprising at least two transmission links that can be moved in translation in a sliding direction with respect to each other and with respect to the pushing device and ejection element,
• wherein the ejection device further comprises at least one adjustment wedge mounted on the pushing device, said adjustment wedge comprising an adjustment surface forming an adjustment angle with respect to a direction substantially perpendicular to the first axis, the transmission chain being mounted on said adjustment surface so that the sliding direction is substantially parallel to said adjustment surface,
• wherein said adjustment wedge comprises a lower surface extending in a direction perpendicular to the first axis and an upper surface forming the adjustment surface forming the adjustment angle with respect to said direction substantially perpendicular to the first axis, the lower surface being applied on the pushing device and the transmission chain being mounted on the upper surface.
