1. A molded product manufacturing system having a blow molding machine, a multi-axis robot, a support frame, and a deburring device, wherein,
a pair of dies of the blow molding machine are arranged so as to open in a first direction substantially parallel to a ground plane,
the multi-axis robot comprises a base portion and a multi-axis arm portion connected to the base portion, and is configured to convey a molded body molded by the blow molding machine by a hand portion mounted on the arm portion,
the support frame has a support surface that supports the base portion, said support surface having a normal defined perpendicular to the support surface,
the deburring device is configured to separate the molded body into a molded main body that will become a molded product and a burr,
the multi-axis robot and the deburring device are arranged at positions displaced from the blow molding machine in a second direction perpendicular to the first direction and a vertical axis,
the multi-axis robot has at least 6 degrees of freedom,
the normal of the support surface and the first direction are in the same direction
the deburring device comprises a pair of abutting members, wherein a size of an opening between the abutting members can be changed, and
the deburring device is configured to separate the burr from the molded main body by colliding the burr with the pair of abutting members while the size of the opening is set so that the molded main body can pass through and the burr collides with the pair of abutting members.
