Abstract
A resin molding method includes: a mold clamping process that clamps a mold, forms a resin flow path, and arranges baffle members in the resin flow path; an injection process that injects a molten resin containing a base material and an anisotropic filler dispersed in the base material from a nozzle into the resin flow path to correct a variation in flow rate of the molten resin on the upstream side of the baffle members and to form a weld on the downstream side of the baffle members by using the baffle members obstructing a flow of the molten resin so that orientation of the filler in the direction in which the weld extends is improved; and a mold opening process that opens the mold so as to take out a resin molded product.
Claims14
A resin molding method comprising:
- clamping a mold so as to form a resin flow path having a gate arranged on a downstream side of a nozzle of a molding machine and having a cavity arranged on a downstream side of the gate and to arrange a baffle member in the resin flow path;
- injecting, from the nozzle into the resin flow path, a molten resin containing a base material and an anisotropic filler dispersed in the base material to correct a variation in flow rate of the molten resin on an upstream side of the baffle member and to form a weld on a downstream side of the baffle member by using the baffle member obstructing a flow of the molten resin so that orientation of the filler in a direction in which the weld extends is improved;
- and
- opening the mold so as to take out a resin molded product formed by solidifying the molten resin.
