Definitions

  • the present invention has been made in order to solve such a problem, and it is possible to improve productivity by reducing a cycle time of a structure to a necessary minimum without making the structure a defective product.
  • the purpose is to provide a machine that can do it.
  • the part near the boundary between the gate and the runner in the lower mold is located outside the product part of the structure and fills the part.
  • the temperature of the molten metal is substantially equal to that of the molten metal in the product portion, and is solidified in a similar manner with a slight delay from the product portion. For this reason, the same temperature as the product part can be detected outside the product part of the structure by the temperature sensor.
  • the low-pressure forming machine according to the present invention it is possible to prevent the trace of the temperature sensor from being formed in the product part even though the temperature of the molten metal is directly detected by the temperature sensor. It is possible to produce high quality and structure.
  • FIG. 2A is an enlarged longitudinal sectional view showing a mold part.
  • FIG. 7 is a cross-sectional view showing an example in which a temperature sensor is provided at a gate of a low-pressure manufacturing machine.
  • FIG. 9A is a cross-sectional view showing a mold used for a gravity-forming machine.
  • FIGS. 1 to 6 what is denoted by reference numeral 1 is for a low-pressure structure according to this embodiment.
  • ⁇ It is a machine.
  • This machine 1 is for manufacturing a cylinder head (not shown) of a motorcycle engine by low-pressure structure.
  • the forging machine 1 has a mold 3 disposed on a furnace body 2, and a control device 4, which will be described later, controls the temperature of the mold 3 and the molten metal 5, and opens and closes the mold 3. The operation and the supply and stop of the molten metal 5 are controlled.
  • the metal material manufactured by the machine 1 is an aluminum alloy.
  • the structure by the machine 1 is performed by pressurizing the inside of the main body 6 of the furnace body 2 with the calo-pressure device 10 while the mold 3 is clamped.
  • the molten metal 5 rises in the stalk 9 from the crucible 8 when the inside of the main body 6 is pressurized, and is supplied into the mold 3 located above.
  • the lower mold 12 has a cavity 18 that opens upward, and is fixed on a base 16 by a support member 19.
  • the lower mold 12 and the upper mold 11 are provided with a heater (not shown) for preheating them to a manufacturing temperature, and a water for maintaining the mold temperature at the time of manufacturing constant.
  • a cooling device (not shown) is provided. The temperature of the heater and ON / OFF of the water-cooled cooling device are controlled by a control device 4 described later.
  • the manufacturing condition setting device 36 sends a mold opening signal to the drive device 13 after the time measured by the timer reaches the solidification time.
  • the mold opening signal is sent to the driving device 13, the upper mold 11 is raised by the driving device 13, and the mold is opened (Step 10 ⁇ Step 11).
  • step S6 If the determination result in step S6 is YES, that is, if it is determined that the temperature sensor 26 is functioning normally and V, the manufacturing condition setting device 36 controls the temperature sensor 26 in step S12. The temperature of the molten metal 5 in the runner 21 is detected. At this time, the temperature detected by the temperature sensor 26 changes as shown in FIG. 6, and gradually decreases as the solidification of the molten metal 5 progresses after reaching the maximum temperature.
  • the manufacturing condition setting device 36 sends a stop signal to the pressurizing pressure controller 35. When this stop signal is sent to the pressurizing pressure controller 35, the pressurizing device 10 stops supplying the inert gas, and the pressurization of the molten metal 5 is completed (step S14).
  • FIG. 7 is a cross-sectional view showing another example in which a temperature sensor is provided at the gate of a low-pressure manufacturing machine.
  • the same reference numerals are given to members that are the same as or equivalent to those described with reference to FIGS. Detailed description is omitted as appropriate.
  • the temperature sensor 26 is the same as that used in the first embodiment, and the temperature detection unit 28a has the first inner wall surface force of the feeder unit 56 projecting along the mold opening direction.
  • the mold is mounted on 52. That is, in this case as well, the molten metal 5 is set later than the cavities 54 and 55.
  • a temperature sensor 26 is provided at the portion to be hardened. When the molten metal 5 is supplied to the bottoms of the cavities 54 and 55 using the sprue 58 and the runner 59 as shown in the mold 51 shown in FIGS. 9A and 9B, the two-dot chain line in FIG.
  • the temperature sensor 26 can be provided at the gate 58.
  • the control device controls the temperature of the molten metal 5 in the pusher portions 56 and 57 or in the spout 58 by the temperature sensor 26 as shown in Step P4. Is detected. As shown in FIG. 11, the temperature detected by the temperature sensor 26 rises sharply after the start of production (start of pouring of molten metal), and gradually decreases after a state in which it does not change for a certain period. After that, in step P5, the control device 4 determines that the temperature sensor 26 is normal when the maximum value of the temperature detected by the temperature sensor 26 is within a predetermined temperature range. When the above-mentioned maximum value is out of the temperature range, the control device 4 determines that the temperature sensor 26 is functioning normally and that the temperature sensor 26 is abnormal (abnormal).
  • the temperature of the molten metal 5 is directly detected by the temperature sensor 26, and the mold opening timing can be determined based on this temperature.
  • the mold 51 can be opened at an optimal time according to the state of the structure.
