Claims

[Scope of utility model registration request]

In a device that operates an extrusion plate after opening the mold and extrudes a molded product from the mold using a plurality of extrusion pins attached to the extrusion plate, a predetermined extrusion pin among the extrusion pins is activated when the extrusion plate is operated. In order to make the ejector pin move later than other ejector pins, the ejector pin is supported movably in the axial direction in a support hole formed through the ejector plate, and when the ejector plate moves a predetermined amount, The predetermined extrusion pin is configured to receive a pressing force from the extrusion plate and move integrally with the extrusion plate, and the pin portion is returned to the support hole and is movable in the axial direction so as to be continuous with the predetermined extrusion pin. The return pin portion protrudes from the support hole until the predetermined extrusion pin moves integrally with the extrusion plate, and the return pin portion abuts and supports the substrate on which the mold is attached during mold matching. 1. An extrusion mechanism for a plastic mold, characterized in that it is configured to move in the direction of entering the hole and return the predetermined extrusion pin to its original position.
