1 and 42 are inserts for forming the inner hole of the pellet. Into this gap, the material is injected from the nozzle opening of 61 of the injection molding machine according to the embodiment of the present invention shown in FIG.
It is possible to uniformly fill the pellet material into the mold made up of two parts. Later, the device 51 located outside the 61.320 mold is heated, pressure, temperature, etc. are measured, and the information is transmitted to a predetermined measuring device 75, which will be described later, via the 1,1-t conductor 52. let In FIG. 5, 66 is a material supply port, and 62 is an injection cylinder. 64 is a pressurizing device, which is a device for injecting the pellet material in the injection cylinder 62 from the nozzle opening 61. Reference numeral 71 is a control device that can adjust the drive of the pressurizing device 61, and 72 is a +7- lead wire connected from the control device 71 to the measuring device 76. By giving certain instructions to the measuring device in 73, it is possible to check the performance and rank of the manufactured product based on the heating conditions, pressure, and temperature conditions in 51, and with that information, the ζfiiJ control device in 71 can be checked. It also makes it possible to control the device itself.
