Abstract
A molding machine includes: a mold that forms a molded product; an extrusion pin that transmits to the molded product an extrusion force for demolding the molded product from the mold, wherein the extrusion pin is inserted in the mold; and a control device configured to control the extrusion force of the extrusion pin. The control device controls the extrusion force at a first timing elapsed a first elapsed period so as to be greater than the extrusion force at second timing elapsed a second elapsed period. The first elapsed period is an elapsed period from a predetermined start point. The second period is an elapsed period from the start point and a shorter than the first elapsed period.
Claims7
A molding machine comprising:
- a mold that forms a molded product;
- an extrusion pin that transmits to the molded product an extrusion force for demolding the molded product from the mold, wherein the extrusion pin is inserted in the mold;
- and
- a control device configured to control the extrusion force of the extrusion pin;
- wherein the control device controls the extrusion force at a first timing elapsed a first elapsed period so as to be greater than the extrusion force at second timing elapsed a second elapsed period, wherein the first elapsed period is an elapsed period from a predetermined start point, wherein the second period is an elapsed period from the start point and a shorter than the first elapsed period.
A method for extruding a molded product comprising:
- injecting in a mold a molding material for forming the molded product;
- and
- transmitting to the molded product an extrusion force for demolding the molded product from the mold, wherein the extrusion force at a first timing elapsed a first elapsed period is greater than the extrusion force at second timing elapsed a second elapsed period, wherein the first elapsed period is an elapsed period from a predetermined start point, wherein the second period is an elapsed period from the start point and a shorter than the first elapsed period.
