Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 The utility model provides a hydraulic molding feeder 1 structure, comprising: a feeder 1, a mixing pressurizing machine 2 connected to the feeder 1, the mixing pressurizing machine 2 is provided with a feeding pipe 5 for installing a shot head 51; a fixed plate 7 is provided on the shot head 51, the fixed plate 7 is adapted to a guide rail 9 and moves along the direction thereof, a lubricating member 8 is provided on the fixed plate 7, during injection molding, the shot head 51 is driven by a driving member 6 to align with a feed port 41 of a mold 4 of a hydraulic molding machine 3, and the lubricating member 8 presses the mold 4 to make the internal lubricating oil flow into the fixed plate 7 and flow out to between the guide rail 9 and the fixed plate 7.

[0025] In this embodiment, after each component or mechanism is debugged and qualified, first, the core component in the mold 4 is placed in the mold cavity of the mold 4, and the hydraulic molding machine 3 is started to lock the mold 4 downward, and then the driving member 6 is started to drive the fixed plate 7 along the guide rail 9 to drive the shot head 51 to push into the feed port 41 of the mold 4, and the control switch is turned on, and then the entire feeder 1 and the mixing and pressurizing machine 2 start to run, and the liquid material is first drawn from the feeder 1 and then mixed and pressurized in the mixing and pressurizing machine 2, and the liquid material enters the mold cavity of the mold 4 through the pipeline after the molding feeder 1 runs. After the injection is completed, the shot head 51 is withdrawn under the drive of the driving member 6, and the shot head 51 is separated from the feed port 41 of the mold 4. The hydraulic molding machine 3 starts to run, the liquid material is solidified and molded at high temperature, the mold is opened to take out the product, and after completion, the next mold product molding is repeated. At the same time, after the shooting head 51 is aligned with the feed port 41, the lubricating part 8 is squeezed, and the lubricating liquid inside it is released, so that the liquid flows out into the guide rail 9 through the fixed plate 7, thereby realizing the operation of automatically adding lubricating liquid during the travel of the fixed plate 7, without the need for human control, and the feed amount is accurate, thereby improving the service life and operating efficiency of the mechanism.

[0026] Specifically, the lubricating member 8 comprises a cylinder body, in which a liquid delivery chamber 82 and a liquid storage chamber 81 are separated and arranged, and a through hole 83 is arranged between the two.

[0033] The above-mentioned lubricating liquid flows from the liquid filling chamber 81 through the through hole 83 to the horizontal liquid inlet pipe 841 and the vertical liquid inlet pipe 842 and then to the liquid outlet 846, and flows out to the outside of the fixed plate 7 through the slender tube 72, so that the lubricating liquid is automatically added between the fixed plate 7 and the guide rail 9, making the fixed plate 7 smoother when moving.

[0034] Furthermore, a bifurcated tube 73 is provided at both ends of the elongated tube 72, and the opening of the bifurcated tube 73 is located at the bottom of the fixed plate 7.
