Manual high-pressure air injection, on the other hand, involves manually controlling the air volume in a valve to complete the injection molding of the pole in the mold, requiring strict operator proficiency. However, in actual production, improper control of the high-pressure air pressure often results in surface defects in the formed poles, even rendering them unusable and scrapped. Hydraulic cylinder injection is a rigid injection method that cannot achieve flexible control during the process. Utility Model Content

[0025] Specific embodiment 1 of the single pneumatic sealing type injection cylinder device of the utility model:

[0026] See also Figure 1 、 Figure 2 、 Figure 3 The single pneumatic sealed injection cylinder device of the present invention includes an injection input pipe 1, an injection cylinder 2, a one-way pneumatic valve, an electromagnetic control valve 4, and an injection output pipe 5. The injection cylinder 2 is connected to the injection input pipe 1 and to the one-way pneumatic valve 3; the one-way pneumatic valve 3 is respectively connected to the injection cylinder 2 and the electromagnetic control valve 4 and is connected to the molding mold 6 through the injection output pipe 5. The electromagnetic control valve 4 controls the disconnection and opening of the one-way pneumatic valve 3 by controlling the input and blocking of high-pressure air in the one-way pneumatic valve 3, thereby realizing the injection of supplementary mixed material into the injection cylinder 2 and the injection of the mixed material in the injection cylinder 2 into the molding mold 6.

[0027] Specifically, a support frame 8 is provided below the injection cylinder 2, and the electromagnetic control valve 4 is provided on the support frame 8; the one-way pneumatic valve 3 is provided at the side position of the bottom end of the injection cylinder 2. During use, when the injection cylinder 2 needs to be refilled, the electromagnetic control valve 4 is powered on and opened, and controls the input of high-pressure air in the one-way pneumatic valve 3, so that the one-way pneumatic valve 3 is disconnected. At this time, the mixed material is quickly injected into the injection cylinder 2 through the injection input pipe 1 to achieve the replenishment of the injection cylinder 2 and avoid leakage along the injection input pipe 1; when the injection is started, the electromagnetic control valve 4 is powered off and closed, and controls the blocking of the high-pressure air in the one-way pneumatic valve 3, so that the one-way pneumatic valve 3 is opened. At this time, the mixed material in the injection cylinder 2 is injected into the molding mold 6 through the injection output pipe 5 to achieve the mold injection molding process.

[0028] Specifically, an air pipe 7 is connected between the one-way pneumatic valve 3 and the electromagnetic control valve 4. The electromagnetic control valve 4 controls the flow of high-pressure air into the air pipe 7 by turning it on and off, thereby controlling the opening and closing of the one-way pneumatic valve 3. When the electromagnetic control valve 4 is powered on, it opens, allowing high-pressure air to flow into the air pipe 7 and lock the one-way pneumatic valve 3, allowing the mixed material to be injected into the injection cylinder 2. When the electromagnetic control valve 4 is powered off, it closes, blocking the flow of high-pressure air into the air pipe 7, allowing the one-way pneumatic valve 3 to open and inject the mixed material in the injection cylinder 2 into the molding die 6. During use, when the electromagnetic control valve 4 is powered on, it opens. The electromagnetic coil generates an electromagnetic force that directly attracts the valve core, causing the valve core to shift, ensuring that high-pressure air enters the one-way pneumatic valve 3 along the air pipe 7 and locks the one-way pneumatic valve 3. When the electromagnetic control valve 4 is powered off, it closes, the electromagnetic force disappears, the valve core returns to its original position due to the spring, and the high-pressure air is blocked. The one-way pneumatic valve 3 opens, allowing the mixed material in the injection cylinder 2 to be injected into the molding die 6.

[0029] Specific embodiment 2 of the single pneumatic sealing type injection cylinder device of the utility model:

[0030] Based on the technical concept of the present invention described above, or based on the specific embodiment of the present invention described above, another embodiment is provided below.

[0031] In this embodiment, Figure 1 As shown, a symmetrical leather cover 31 is provided inside the one-way pneumatic valve 3 along its length. The one-way pneumatic valve 3 is opened and closed by locking and resetting the symmetrical leather cover 31. During use, when the electromagnetic control valve 4 is energized, high-pressure air enters the one-way pneumatic valve 3 along the air pipe 7, locking the internal leather cover 31 and opening the one-way pneumatic valve 3. When the electromagnetic control valve 4 is de-energized, the high-pressure air is blocked, the leather cover of the one-way pneumatic valve 3 is reset, and the interior is opened, thereby opening the one-way pneumatic valve 3.

[0032] Internal threaded holes 11 are provided at both ends of the one-way pneumatic valve 3, and the internal threaded holes 11 are threadedly connected to a quick connector 12. A vacuum bracket sealing ring 13 is embedded in the middle position of the quick connector 12 and is clamped by a clamp. The above method is used for quick assembly, which is convenient for quick disassembly and cleaning, and is convenient for continued use next time, while avoiding leakage problems.

[0033] Specific embodiment 3 of the single pneumatic sealing type injection cylinder device of the utility model:

[0034] Based on the technical concept of the present invention described above, or based on the specific embodiment of the present invention described above, another embodiment is provided below.

[0035] A piston 9 is mounted at the top of the injection cylinder 2. The piston 9 is fitted with a speed reducer 10 through an interference fit. The speed reducer 10 is used to drive the piston 9 up and down through rotation. Adjusting the speed of the speed reducer 10 adjusts the initial speed of the piston's up and down motion. Adjusting the initial speed of the piston's up and down motion avoids high starting speeds and excessive pressure, which can damage the pipeline. The initial speed of the up and down motion can be used to inject material at a constant or variable rate. Specifically, the speed of the piston controlled by the speed reducer can be adjusted according to the molding process (injection-holding pressure), allowing for a staged injection of the material at a constant or variable rate.

[0036] The use process of the single pneumatic sealing type injection cylinder device of the utility model is as follows:

[0037] In the state of replenishing the mixed material, the electromagnetic control valve 4 is energized and opened, and its electromagnetic coil generates electromagnetic force, which directly attracts the valve core, and the valve core is displaced, ensuring that high-pressure air enters the one-way pneumatic valve 3 along the air pipe 7, realizing the locking of the one-way pneumatic valve 3, and the mixed material is quickly filled into the injection cylinder 2 along the input pipe 1 until the material is fully filled;

[0038] When injection is initiated, the solenoid control valve 4 is de-energized and closed, the electromagnetic force disappears, the valve core is reset by the spring, the high-pressure air is blocked, and the one-way pneumatic valve 3 opens. The mixture gradually moves downward along with the injection cylinder piston, driving the mixture along the injection output pipe 5 and into the forming mold 6, achieving completely flexible injection. The mixture inside the forming mold 6 gradually undergoes a chemical reaction and solidifies as the temperature changes. The mixture inside the injection output pipe 5 is forced to flow slowly, filling the internal defects of the pole and ensuring the pole's outer contour is perfectly formed. When the pole forming set time expires, before the operator opens the forming mold 6, the hydraulic cylinder automatically drives the pipe to separate from both sides, allowing the pole to be demolded.

[0039] Through the above description of the specific embodiment of the single pneumatic sealed injection cylinder device of the utility model, it can be seen that the single pneumatic sealed injection cylinder device of the utility model includes an injection input pipe for inputting a mixture into the injection cylinder; an injection cylinder for accommodating the mixture; a one-way pneumatic valve for controlling the injection of the mixture into the molding mold; an electromagnetic control valve for realizing the injection of the mixture into the injection cylinder and the injection of the mixture in the injection cylinder into the molding mold by controlling the disconnection and opening of the one-way pneumatic valve; an injection output pipe for inputting the mixture into the molding mold; the injection cylinder is connected to the injection input pipe and connected to the one-way pneumatic valve for realizing feeding and injection; the one-way pneumatic valve is respectively connected to the injection cylinder and the electromagnetic control valve and is connected to the molding mold through the injection output pipe, and the electromagnetic control valve controls the disconnection and opening of the one-way pneumatic valve by controlling the input and blocking of high-pressure air in the one-way pneumatic valve, thereby realizing the replenishment of the mixture into the injection cylinder and the injection of the mixture in the injection cylinder into the molding mold. The utility model utilizes an electromagnetic control valve to control the opening and closing of a one-way pneumatic valve; when the material filling is started, the electromagnetic control valve is energized to open and controls the input of high-pressure air in the one-way pneumatic valve, so that the one-way pneumatic valve is disconnected, and at this time the mixed material is injected into the injection cylinder through the injection input pipe to realize the material filling of the injection cylinder; when the material injection is started, the electromagnetic control valve is de-energized to close and controls the blocking of the high-pressure air in the one-way pneumatic valve, so that the one-way pneumatic valve is opened, and at this time the mixed material in the injection cylinder is injected into the molding mold through the injection output pipe to realize the mold injection molding process, realize flexible injection, solve the disadvantage that the rigid injection of the hydraulic oil cylinder cannot flexibly control the process, and can be applied to the field of gas, liquid and dust mixtures.
