Beschreibung
Zusammenfassung:	A vertical type injection molding machine includes a fixed mold, a movable body, a lift mechanism, a plurality of weights, and a plurality of pulleys is provided. The fixed mold is supported by a support frame provided on a base. The movable body includes a movable mold. The movable mold is approached to and moved away from the fixed mold. The lift mechanism lifts and lowers the movable body, thereby causing the movable mold to approach and move away from the fixed mold. The weights function as a counterweight of the movable body. The total weight of the weights is the same as the weight of the movable body. Each weight is coupled to the movable body by a wire. The pulleys are provided in an upper portion of the support frame. One of the wires is placed over each pulley. Each wire connects the corresponding weight to the movable body.
