Abstract
This method of manufacturing a lid made of a transparent resin comprises a step of introducing a resin into a cavity for molding a protrusion continuous with a cavity for molding a lid in a die; a step of forming a molded body including a lid and a protrusion continuous with the lid by solidifying the resin in the cavity for molding a lid and the cavity for molding a protrusion, respectively; a step of separating the molded body from the die by ejecting an ejector pin to the protrusion; and a step of separating the protrusion from the lid.
Claims18
A method of manufacturing a lid made of a resin for a case for accommodating a solid-state imaging device, the method comprising:
- a molding step of integrally injection-molding from a transparent resin a molded body for a lid made of a resin comprising a lid-forming part, at least one gate part continuous with the lid-forming part, and at least one optional protrusion continuous with the lid-forming part;
- and
- a takeout step of taking the molded body out of a die by causing an ejector pin to eject the gate part and/or protrusion.
A method of manufacturing a lid made of a transparent resin, the method comprising:
- a step of introducing a resin into a cavity for molding a protrusion continuous with a cavity for molding a lid in a die;
- a step of forming a molded body comprising a lid and a protrusion continuous with the lid by solidifying the resin in the cavity for molding a lid and the cavity for molding a protrusion, respectively;
- a step of separating the molded body from the die by ejecting an ejector pin to the protrusion;
- and
- a step of separating the protrusion from the lid.
A method of manufacturing a lid made of a transparent resin, the method comprising:
- a step of introducing a resin through a cavity for molding a gate part continuous with a cavity for molding a lid in a die;
- a step of forming a molded body comprising a lid and a gate part continuous with the lid by solidifying the resin in the cavity for molding a lid and the cavity for molding a gate part, respectively;
- a step of separating the molded body from the die by ejecting an ejector pin to the gate part, and
- a step of separating the gate part from the lid.
A method of manufacturing a lid made of a transparent resin, the method comprising:
- a step of introducing a resin into and in a cavity for molding a protrusion continuous with a cavity for molding a lid in a die, and together introducing a resin through a cavity for molding a gate part continuous with the cavity for molding a lid;
- a step of forming a molded body including a lid and a protrusion and a gate part continuous with the lid by solidifying the resin in the cavity for molding a lid, the cavity for molding a protrusion and the cavity for molding a gate part, respectively;
- a step of separating the molded body from the die by ejecting an ejector pin to the protrusion and the gate part;
- and
- a step of separating the protrusion and the gate part from the lid.
