<p>A temperature control device for a proximal portion of a heating cylinder of an injection molding machine capable of performing check and control of a flow rate of a heat medium easily, improving maintainability and also reducing a manufacturing cost. At least one pair of through holes (13, 14) for flowing the heat medium for temperature control are formed in a jacket (11) to be attached to a proximal portion of a heating cylinder of an injection molding machine. In a passage by pipes (18, 19) connecting the through holes and forming the passage with the through holes, a flow-rate control mechanism (16) and a flow-rate detection mechanism (17) for the heat medium flowing in the passage are arranged. The heat medium is supplied to the passage to control temperature of the proximal portion of the heating cylinder. The flow-rate control and detection mechanisms (16, 17) are arranged on the same side as an operation panel of the injection molding machine, whereby an operator can check and control the flow rate of the medium at the same location where an ordinary operation of the injection molding machine is performed. <IMAGE></p> |
