Abstract
A molding machine in which a load cell unit is mounted on an end portion of one of a plurality of connecting bars elastically deformable (extensionally deformable) due to a load (tensile load) during the operation of molding. At least partially any connecting bar where the load cell unit is not mounted, that is, any connecting bar other than the predetermined connecting bar where the load cell unit is mounted, includes a portion whose diameter is made a predetermined distance smaller than a diameter of the predetermined connecting bar where the load cell unit is mounted. Thus, the quantities of deformation can be equalized all over the connecting bars without using any dummy load cell unit.
