AI Technical Summary
Technical Problem
In gigacasting, large product shapes can cause deformation during mold separation due to insufficient extrusion amount or deformation in the mold direction, necessitating a method to adjust the extrusion amount of the extrusion pin.
Method used
A method comprising an ejector pin, an ejector plate, and an adjustment mechanism that adjusts the ejector pin's ejector plate side for determining the amount of ejection of the ejector pin, and an adjustment mechanism provided at the ejector pin on the ejector plate side for adjusting the extrusion amount based on product dimensions and deformation direction.
Benefits of technology
The extrusion amount of the extrusion pins can be appropriately adjusted during demolding, minimizing deformation and ensuring precise mold separation.

Abstract
The amount of ejection pins is appropriately adjusted when demolding from the mold. [Solution] The mold device 20 includes an ejector pin 22 provided in the mold 21, an ejector plate 23 that pushes out the ejector pin 22, and an adjustment mechanism 24 provided at the end of the ejector pin 22 on the ejector plate 23 side for adjusting the amount of ejector pin 22. The control device 10 acquires the product dimensions, deformation amount, and deformation direction of the product 25 to be processed, determines whether the deformation amount is within a predetermined value, and if the deformation amount is greater than the predetermined value and the deformation direction is deformation in the ejection direction, it reduces the amount of ejector pin 22 by the adjustment mechanism 24, and if the deformation amount is greater than the predetermined value and the deformation direction is deformation in the mold direction, it increases the amount of ejector pin 22 by the adjustment mechanism 24.
