ABSTRACT:
An apparatus for measuring the weight of a molded resin article in conjunction with an injection molding cycle and judging whether the molded article is acceptable or rejective. A belt conveyor is provided below a mold for injection molding. Articles (connector housings) molded with the mold are dropped out of the mold onto the belt conveyor when the mold is opened, and transported to a weight checker by means of the belt conveyor. In the weight checker, the weight of the transported articles is measured. The measured weight is compared with a predetermined reference weight. If the measured weight is within a predetermined permissible range with respect to the reference weight, it is judged that the molded articles are acceptable, and then the molded articles are dropped into an acceptance box. On the other hand, if the measured weight is out of the predetermined permissible range with respect to the reference weight, it is judged that the molded articles possibly include a reject, and then the molded articles are dropped into a rejection box.
