Description

Technical Field

[0001] The invention relates to an injection encoder of a die-casting machine and a rear limit anti-collision device under a servo valve control failure mode thereof, in particular to an anti-collision protection device for an injection material connection rod. Background Art

[0002] In modern industrial production, die-casting machines, as an important metal forming equipment, are widely used in the production of parts in the automotive, aviation, electronics and other industries. The working principle of the die-casting machine is to use high pressure to inject molten metal into the mold, and form parts of the desired shape after cooling and solidification. In the operation of the die-casting machine, the injection system is one of the key parts, which is responsible for injecting molten metal into the mold at high speed and high pressure. In order to accurately control the injection process, modern die-casting machines are usually equipped with a servo valve control system, which monitors and adjusts the position and speed of the injection rod through an encoder.

[0003] The injection coding components of the die-casting machine are very susceptible to damage due to the influence of high-frequency oscillation, resulting in functional failure. Especially in the die-casting mold opening stage, whether in automatic tracking or manual injection propulsion mode, if the forward position is out of control, the cooling water connector of the injection material connecting rod may collide with the container, causing damage. Once such a failure occurs, the cooling water may spray into the injection container or flow into the aluminum liquid holding furnace next to the die-casting machine, which will not only cause fluctuations in product quality, but may also trigger hydrogenation reactions and cause explosion accidents, which will lead to machine tool shutdown, increased failure rates, and waste of spare parts costs, causing huge economic losses to the company.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an anti-collision protection device for the injection molding connecting rod. Summary of the invention

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Example

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a technical solution for an anti-collision protection device for a pressure-injection material connecting rod: it includes a base 1, and an anti-collision limit rod 2 is vertically installed on the side of the base 1. The base 1 and the anti-collision limit rod 2 are arranged in a T-shape to ensure the stability and impact resistance of the structure.

[0023] Among them, an anti-collision rod sleeve 3 is sleeved on the front end of the anti-collision limit rod 2, and the anti-collision rod sleeve 3 is connected to the anti-collision limit rod 2 through multiple groups of anti-collision buffer springs 31. These springs 31 can absorb the impact force generated during the collision process and reduce the damage to the injection material connecting rod.

[0024] Among them, a guide sliding hole 21 is opened at the end of the anti-collision limit rod 2, and a guide sliding rod 32 is slidably connected in the guide sliding hole 21. A limit block is set at the end of the guide sliding rod 32, and the limit block slides along the guide sliding hole 21. The limit sliding sleeve 22 is installed at the opening of the guide sliding hole 21, and is slidably matched with the guide sliding rod 32 to limit the limit block at the end of the guide sliding rod.

[0025] The base 1 is provided with a telescopic opening 11 on the outside, and a pressing block 4 is arranged inside the telescopic opening 11. An extrusion downslope 42 is arranged inside the pressing block 4, and a movable pressing seat 53 is arranged adjacent to the extrusion downslope 42. An extrusion upslope is arranged outside the movable pressing seat 53, and the extrusion upslope is closely matched with the extrusion downslope.

[0026] Among them, a threaded sleeve 51 is embedded and installed on the top of the base 1, and a bolt 52 is connected to the inner thread of the threaded sleeve 51. The bottom end of the bolt 52 is rotatably connected to a rotating seat 54, and the rotating seat 54 is installed on the top surface of the movable pressure seat 53.

[0027] The top and bottom surfaces of the pressing block 4 are both provided with guide sliding openings 41 , and a guide sliding block 55 is slidably connected in the guide sliding opening 41 . The guide sliding block 55 is installed on the inner wall of the telescopic opening 11 .

[0028] Specifically, by rotating the bolt 52 to move along the threaded sleeve 51, the movable pressing seat 53 is driven to squeeze the pressing block 4, driving the pressing block 4 to extend, and further extending the fixed size of the base 1 to meet the installation requirements of different positions.

[0029] In this embodiment, when the injection encoder or servo valve fails, the anti-collision limit rod 2 and the anti-collision rod sleeve 3 can effectively limit the injection material connecting rod to reduce damage to the equipment. The coordinated use of the guide slide rod 32 and the limit slide sleeve 22 improves the positioning accuracy and response speed of the device, ensuring that it can respond quickly in an emergency and protect the safe operation of the die-casting machine. Through the arrangement of the above structure, the injection material connecting rod anti-collision protection device of the present invention can effectively prevent collisions, improve production safety, and reduce downtime and maintenance costs caused by failures.
