摘要： PROBLEM TO BE SOLVED: To transfer a heat axially toward a body of a heating cylinder by inclining an entirety or a part of a mirror surface directed toward a cylinder by reflecting a heat ray from a heater to be formed at a heat insulation cover to an axis of a screw. SOLUTION: Heaters 14 are energized to hold a cylinder 12 at a predetermined temperature, a raw material is filled in the cylinder 12 with a hopper, heated while kneading it by a screw to melt the material, and then the material is injected in a die cavity with a nozzle. Heat rays 27 radiated from the heaters 12 are reflected on a mirror surface 25 to concentrate the heat between the heaters 14 to directly radiate the rays to the cylinder 12, thereby eliminating a fear of heating or overheating of the heaters 14 themselves. To this end, the surface 5 is formed concave to substantially concentrate incident light rays substantially to one point. Outer peripheries 13 of the cylinder 12 are black to low its reflectivity and large heat absorbing rate, thereby enhancing heating efficiency. Thus, the heat rays of the heaters 14 can be directed to favorite positions of the surface 25, and hence heat dissipation into the atmosphere is suppressed and a thermal energy can be effectively utilized.

摘要： PROBLEM TO BE SOLVED: To control the cost reduction of a device and improve its possibilities of future extension and versatility, by a method wherein a key part having one or two or more specified keys is displayed at the extension part of a panel. SOLUTION: On the picture plane 2v of a display, a touch input panel 3 is annexed. The touch input panel 3 is made larger than the picture plane 2v so as to provide a panel extension part 3e extended outside the picture plane 2v. On the surface of the panel extension part 3e, a ten key part Sa having one or two or more specified keys (k), a function key part Sb including a picture plane changing-over key and the like and a cursor key part Sc are printed. Since various key pattern parts 13a, 13b and 13c are displayed on the picture plane 2v, the setting of molding conditions and the like can be carried out by selecting arbitrary key pattern part 13a. Further, input can also be carried out by the ten key part Sa, the function key part Sb and the cursor key part Sc.

摘要： PURPOSE:To obtain a controller for a molding machine which can perform a proper temp. control by providing a control part wherein temp. of an object to be controlled is detected through a temp. detector when the working time reaches a specified time and when the detected temp. does not reach a specified temp., it is judged to be abnormal. CONSTITUTION:A control part 28 heats or cools an object to be controlled 14 through a temp. control part 16. In addition, the working time of the temp. control part 12 is measured through a timer part 26 and temp. of the object to be controlled is detected through a temp. detector 16 when the working time reaches a specified time and when the detected temp. does not reach a specified temp, it is judged to be abnormal. It is possible thereby to detect abnormal condition of the temp. detector, etc., and to prevent the object to be controlled from overheating or supercooling.

摘要： PURPOSE:To absorb a deviation in a control position based on a time-lag in response, by a method wherein a control position is set up, by moving a movable member at a regular speed and a moving quantity is stored, by moving the movable member at a lower speed than the regular speed. CONSTITUTION:To begin with, in case of setting a control position by a position setting mode, the control positions P1-Pn of a movable member 2 during a sequence action are set up by proxcimity switches LS1-LSn. In this instance, a movable platen and injection plunger which are the movable members are moved at a regular speed which is an original moving speed. Then memory setting of a moving quantity is performed by changing to a memory mode end, and position data based on the moving quantity of the movable member 2 to be detected through a second position detector 20 are stored into memory areas each by corresponding to the proxcimity switches LS1-LSn each of a first position detector 10. In this case, a speed of a speed setting device is selected so that the moving speed of the movable member 2 is decelerated to the lower speed than the regular speed.

摘要： PURPOSE:To enable improving of accuracy of a molded work, saving of a labor, and reducing of a manufacturing cost, by detecting a trouble on a machine under a molding process through monitoring of a clamping time, an injecting primary pressure time, a weighing time and a molding cycle time. CONSTITUTION:A clamping time, an injecting primary pressure time, and a one cycle time are measured in order by a counter 1, and the measuring times are inputted in a memory part 2 and a comparing part 3. Further, each motion stroke time is monitored at the comparing part 3 by means of data of timers 6 and 7 determined from a preceding reference time. If one molding cycle is completed, each motion stroke time of a current molding cycle serves a reference time for a following molding cycle, and when a partial motion stroke time in one molding cycle deviates from a data of a timer, the occurrence of a trouble is detected.
