An injection oil cylinder 101 is arranged on the injection machine, the injection oil cylinder 101 provides injection force for the injection machine, and the injection oil cylinder 101 and the guide rail fixing oil cylinder 4 are both connected with the electromagnetic valve. Before the injection process of the injection machine, the injection nozzle of the injection machine needs to be aligned with the injection port, and the calibration work of the injection machine is completed through the translation guide rail 3 below the injection plane. After the calibration of the injection machine is completed, the electromagnetic valve is powered on, the injection oil cylinder 101 is filled with oil to gradually push the injection rod to perform an injection process, and in the process, because the injection force has a reaction force on the translation guide rail 3, if the thrust force is too large, the translation guide rail 3 can be mechanically damaged. The guide rail fixing oil cylinder 4 is fixed below the injection flat plate 2, when the electromagnetic valve is electrified, the injection oil cylinder 101 is filled with oil, meanwhile, the guide rail fixing oil cylinder 4 is filled with oil, the acting force direction of the guide rail fixing oil cylinder 4 is opposite to the reaction force direction of the injection oil cylinder 101, and the two acting forces can play a role in mutual offset.
Because the thrust of some injection cylinders 101 is larger, the reverse acting force provided by the guide rail fixing cylinder 4 needs to be larger, therefore, the guide rail fixing cylinder 4 needs to be better matched, the casing of the guide rail fixing cylinder 4 comprises a cylinder seat 401 and a front end cover 402, the cylinder seat 401 and the front end cover 402 are connected to form a cylinder inner cavity, the front end cover 402 is provided with a first oil inlet hole 404, the first oil inlet hole 404 penetrates from the cylinder inner cavity to the outside of the casing, the cylinder seat 401 is provided with a second oil inlet hole 405, and the second oil inlet hole 405 penetrates from the cylinder inner cavity to the outside of the casing. During injection, the second oil inlet hole 405 is used for oil inlet, when the oil is expected, the first oil inlet hole 405 is used for oil inlet, and no matter what process is carried out, the acting force of the guide rail fixing oil cylinder 4 is opposite to the reaction force direction of the injection oil cylinder 101 all the time.
The piston rod 403 of the guide rail fixing oil cylinder 4 is also provided with a CG-type piston sealing ring, a fluorine rubber O-shaped ring, a guide belt, a Glare ring, a sealing ring and a dustproof ring, which are all used for improving the stability, the tightness and the dustproof performance of the guide rail fixing oil cylinder 4, and under the matching of the above parts, the guide rail fixing oil cylinder 4 can provide enough acting force to offset the acting force of the injection oil cylinder 101.
