A pressure regulating mechanism for a die casting machine

Abstract

This utility model discloses a pressure boosting and adjusting mechanism for a die-casting machine, belonging to the technical field of die-casting machines. It includes a frame and a fixed shaft, with a fixed frame at the upper end of the frame, and a hydraulic rod inside the fixed frame. This utility model solves the problem of the inability to adjust the pressure boosting magnitude and processing time, which limits the equipment's use and easily leads to slow extrusion speed and low processing efficiency. This utility model allows for the fixing or non-fixing of the first support rod and the fixed column. When fixed, the length of the corresponding power arm can be controlled. The shorter the power arm, the shorter the extension distance required by the hydraulic rod, and the shorter the processing time; conversely, the longer the extension distance required by the hydraulic rod, the longer the processing time. When the first support rod and the fixed column are not fixed, the speed is fast in the initial stage of die casting, and slows down but remains powerful in the later stage, ensuring both die casting speed and efficiency.

Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, specifically to a pressure boosting and adjusting mechanism for a die casting machine. Background Technology

[0002] When a die-casting machine is in use, it uses pressure to hydraulically inject molten metal into a mold for cooling and shaping. When extruding the metal into the mold, a pressure-boosting mechanism is needed to amplify the force. However, general pressure-boosting mechanisms have some drawbacks, such as:

[0003] Typical pressure adjustment mechanisms cannot adjust the pressure level or processing time during use, which limits the equipment's usability, leading to slow extrusion speeds, low processing efficiency, and ultimately hindering its operation. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure boosting adjustment mechanism for a die-casting machine, which can adjust the die-casting speed and the amount of pressure boosting, and can solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a frame and a fixed shaft. A fixed frame is provided at the upper end of the frame, and a hydraulic rod is provided inside the fixed frame. A telescopic mechanism is provided on the side of the hydraulic rod and embedded inside the fixed frame. The fixed shaft is rotatably disposed inside the frame. A first support rod and a second support rod are respectively provided on the side of the fixed shaft. The length of the first support rod is greater than the length of the second support rod, and the side of the second support rod is connected to the output mechanism.

[0006] Preferably, the telescopic mechanism includes a fixed rod, a support spring, and a limiting rod. The fixed rod is disposed on both sides of the hydraulic rod, and the support spring is disposed inside the fixed rod. The end of the fixed rod away from the hydraulic rod is penetrated by the limiting rod, which is slidably disposed inside the fixed rod.

[0007] Preferably, the fixing frame has symmetrical locking holes on both sides, with the locking hole being circular on the side near the hydraulic rod and rectangular on the other side.

[0008] Preferably, the limiting rod has a slot inside, and the rectangular ends of the slot and the slot hole respectively engage with the locking rod.

[0009] Preferably, a fixing post is provided at the end of the extension of the hydraulic rod, and connecting posts are provided on both sides of the fixing post. The fixing post and the connecting posts are slidably disposed inside the first support rod, and a fixing hole is provided on the side of the first support rod.

[0010] Preferably, the output mechanism includes a connecting rod and a push rod, the push rod being slidably disposed at the bottom of the frame, and the connecting rod being rotatably disposed at the end of the second support rod and the connecting rod adjacent to each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention allows for the fixing or non-fixing of the first support rod and the fixed column. When fixed, the length of the power arm can be controlled. A shorter power arm requires a shorter extension distance for the hydraulic rod, resulting in a shorter processing time. Conversely, a longer power arm requires a longer extension distance for the hydraulic rod, resulting in a longer processing time. When the first support rod and the fixed column are not fixed, in the initial stage of movement, the fixed column will abut against the side of the first support rod closer to the fixed shaft, resulting in lower power and faster movement speed. As the fixed shaft rotates and the first support rod moves, the fixed column will move outward along the first support rod, increasing the length of the power arm and gradually increasing the pressure during the movement. This achieves a high speed in the initial stage of die casting and a slower but more powerful speed in the later stage, ensuring both die casting speed and efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1-5 The present invention discloses a pressure adjustment mechanism for a die-casting machine, comprising a frame 1 and a fixed shaft 11. A fixed frame 2 is provided at the upper end of the frame 1, and a hydraulic rod 4 is provided inside the fixed frame 2. A telescopic mechanism is provided on the side of the hydraulic rod 4 and embedded inside the fixed frame 2. The fixed shaft 11 is rotatably disposed inside the frame 1. A first support rod 12 and a second support rod 16 are respectively provided on the side of the fixed shaft 11. The length of the first support rod 12 is greater than the length of the second support rod 16. The side of the second support rod 16 is connected to the output mechanism.

[0022] In this embodiment, the telescopic mechanism includes a fixed rod 5, a support spring 6, and a limiting rod 7. The fixed rod 5 is disposed on both sides of the hydraulic rod 4, and the support spring 6 is disposed inside the fixed rod 5. The end of the fixed rod 5 away from the hydraulic rod 4 is penetrated by the limiting rod 7, which is slidably disposed inside the fixed rod 5.

[0023] In this embodiment, the fixing frame 2 has symmetrically provided locking holes 3 on both sides. The side of the locking hole 3 near the hydraulic rod 4 is circular, and the other side of the locking hole 3 is rectangular.

[0024] In this embodiment, the limiting rod 7 has a slot 8 inside, and the rectangular ends of the slot 8 and the slot 3 are respectively engaged with the locking rod 9.

[0025] It should be noted that the relative height of the hydraulic rod 4 to the fixed frame 2 can be adjusted by moving the hydraulic rod 4. Then, the support spring 6 pushes the limiting rod 7 to move outward, so that the limiting rod 7 is embedded in the locking hole 3. When it is necessary to fix the hydraulic rod 4, the locking rod 9 is embedded in the locking hole 3, so that the locking rod 9 engages with the locking hole 3 and the locking groove 8 respectively, thereby fixing the limiting rod 7. Since the limiting rod 7 and the fixed rod 5 can only move and cannot rotate, the hydraulic rod 4 is fixed to prevent the hydraulic rod 4 from rotating.

[0026] In this embodiment, a fixing post 14 is provided at the end of the extension of the hydraulic rod 4, and connecting posts 15 are provided on both sides of the fixing post 14. The fixing post 14 and the connecting posts 15 are slidably disposed inside the first support rod 12, and a fixing hole 13 is provided on the side of the first support rod 12.

[0027] It should be noted that the fixed column 14 and the connecting column 15 can slide within the first support rod 12, thereby adjusting the relative positions of the fixed column 14 and the connecting column 15 with respect to the first support rod 12. The connecting column 15 is rotatably mounted on both sides of the fixed column 14. When the bolt is passed through the fixing hole 13 and connected to the connecting column 15, the position of the connecting column 15 will be effectively fixed, thereby preventing the fixed column 14 and the first support rod 12 from shifting relative to each other.

[0028] In this embodiment, the output mechanism includes a connecting rod 17 and a push rod 18. The push rod 18 is slidably disposed at the bottom of the frame 1, and the connecting rod 17 is rotatably disposed at one end of the second support rod 16 and the connecting rod 17.

[0029] It should be noted that when the first support rod 12 moves downward, it will cause the fixed shaft 11 to rotate, and the second support rod 16 will also rotate, thereby driving the push rod 18 to move through the connecting rod 17. Since the length of the first support rod 12 is greater than the length of the second support rod 16, the length of the power arm of the equipment is greater than the length of the resistance arm, thus effectively increasing the pressure.

[0030] Working principle: When the equipment is in use, the relative position of the first support rod 12 and the fixed column 14 can be fixed or not fixed as needed. When fixed, the corresponding power arm length can be controlled. The shorter the power arm, the shorter the extension distance required for the hydraulic rod 4 and the shorter the processing time. Conversely, the longer the power arm, the longer the extension distance required for the hydraulic rod 4 and the longer the processing time.

[0031] When the first support rod 12 and the fixed column 14 are not fixed: the hydraulic rod 4 will drive the first support rod 12 to move downward. In the initial stage of movement, the fixed column 14 will abut against the side of the first support rod 12 that is closer to the fixed shaft 11, so the power of the equipment is small and the moving speed of the equipment is faster. As the fixed shaft 11 rotates, after the first support rod 12 moves, the fixed column 14 will move outward along the first support rod 12, thereby increasing the length of the power arm of the equipment, and the pressure will gradually increase during the process of pushing the equipment to move.

[0032] When the first support rod 12 and the fixed column 14 are fixed, the size of the power arm of the equipment is fixed, so a constant force will drive the fixed shaft 11 to rotate, thereby increasing the force to push the push rod 18 to move downward for die casting.
