First, the injection cylinder 1 is partitioned by a piston 1a into an air chamber 1b to which compressed air is supplied and a loading chamber 1c in which an object B to be injected is loaded. The air chamber 1b side is closed by a rear lid 3 provided with an air supply port 3a, and the upper part in the figure near the opening on the loading chamber 1c side is long in the circumferential direction communicating with the inside. A fitting hole 1d is provided, and a fitting groove 1e is provided on the inner circumference. A plate-shaped front door 2 which is guided and fitted by the fitting groove 1e is slidably fitted in the fitting hole 1d, and airtightness is provided on the inner side surface of the fitting groove 1e and the fitting hole 1d. It is adapted to be held by a seal ring 1f fitted in the groove formed. In addition, the air cylinder 4 is provided at the corresponding position of the fitting hole 1d.
Is attached, and the tip of the piston rod 4a of the air cylinder 4 is connected to the front door 2. That is,
The front door 2 is opened and closed by supplying and discharging compressed air.

Next, in the structure of the injection control mechanism 10, the air supply source 11 connects the air supply base pipe 15 through the on-off valve 12 and the air tank 13 to the compressed air controller 14 including the exhaust valve 14a. Further, the air supply pipe 16 formed by branching between the air tank 13 and the compressed air controller 14 and branching the exhaust pipe provided with the exhaust valve 16b, and the air supply valve 16a being interposed is the air of the rear lid 3.
