Description

Technical Field

[0001] This utility model relates to the field of die-casting machine technology, specifically to a quick-release structure based on the hydraulic unit of a die-casting machine. Background Technology

[0002] Die casting machines are industrial equipment that use high pressure to rapidly inject molten metal into a mold cavity and cool it to form a solid shape. They are mainly used to produce precision metal parts such as aluminum alloys and zinc alloys, and are widely used in the automotive, 3C, and home appliance industries. The hydraulic unit is the actuator of the die casting machine. It drives the piston to move through hydraulic oil to complete key actions such as mold opening and closing, metal injection, and part ejection. The performance of the hydraulic unit directly affects the forming accuracy, production efficiency, and product qualification rate of the die casting machine.

[0003] During long-term operation, the hydraulic unit of a die-casting machine often needs to be disassembled from the machine for repair or replacement due to factors such as seal failure, wear of key components, abnormal operation or performance degradation, and hydraulic system contamination. The core component of the hydraulic unit, the hydraulic cylinder, is usually installed with the movable end connected to the mold and the fixed end connected to the machine body, and is generally fixed with bolts. Although this connection method is simple and reliable, it is cumbersome and time-consuming in actual disassembly and installation. Especially in the case of frequent maintenance or emergency repairs, the bolt fixing method not only increases the labor intensity of workers, but may also lead to prolonged downtime and affect production efficiency. Therefore, we have made an improvement and proposed a quick-release structure based on the hydraulic unit of the die-casting machine. Utility Model Content

[0004] The purpose of this utility model is to address the problem that bolt fixing, disassembly and installation processes are cumbersome and time-consuming.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A quick-release structure based on the hydraulic unit of the die-casting machine is used to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] The quick-release structure based on the hydraulic unit of the die-casting machine includes a mounting plate installed on the machine body, and further includes: an annular plate installed on the movable end of the hydraulic cylinder; a plurality of push rods installed on the annular plate; a first cover plate installed on the mold, the first cover plate having an insertion hole; a plurality of trapezoidal blocks slidably installed on the first cover plate; and a first return spring installed between the trapezoidal blocks and the first cover plate.

[0009] As a preferred technical solution of this application, the annular plate is rotatably connected to the movable end of the hydraulic cylinder, and the push rod is rotatably connected to the annular plate.

[0010] As a preferred technical solution of this application, it also includes a pull rod installed on the trapezoidal block, the pull rod being slidably connected to the first cover plate.

[0011] As a preferred technical solution of this application, it further includes: a connecting plate fixedly installed at the fixed end of the hydraulic cylinder; a groove formed on the connecting plate; and an insert block slidably installed on the mounting plate.

[0012] As a preferred technical solution of this application, it further includes: a second cover plate fixedly installed on the mounting plate; a circular plate rotatably installed on the second cover plate; and an arc-shaped rod for driving the insertion block to move, the two ends of the arc-shaped rod being rotatably connected to the circular plate and the insertion block, respectively.

[0013] As a preferred technical solution of this application, it further includes: a limiting hole formed on the mounting plate; a plug rod slidably mounted on the circular plate; and a second return spring mounted between the plug rod and the circular plate.

[0014] Compared with the prior art, the advantages of this utility model are that installation and disassembly are both convenient and quick.

[0015] In the scheme of this application:

[0016] With the trapezoidal block, automatic centering and locking can be achieved by simply rotating the hydraulic cylinder during installation. During disassembly, the connection can be quickly released by simply sliding the trapezoidal block laterally. The entire process does not require traditional fasteners such as bolts, which significantly improves the efficiency of assembly and disassembly. This structural design cleverly utilizes the self-locking principle of the trapezoidal inclined surface and the elastic return characteristics of the spring, which not only ensures the connection strength and working stability, but also achieves truly rapid assembly and disassembly. It effectively solves the problems of cumbersome operation and difficulty in ensuring positioning accuracy in traditional bolt connection methods, and is particularly suitable for die casting production scenarios that require frequent maintenance or rapid mold replacement.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] Example: A quick-release structure based on the hydraulic unit of a die-casting machine includes a mounting plate 17 installed on the machine body 100, and further includes: an annular plate 6 installed on the movable end of the hydraulic cylinder 300; several push rods 5 installed on the annular plate 6; a first cover plate 1 installed on the mold 200, the first cover plate 1 having an insertion hole; several trapezoidal blocks 2 slidably installed on the first cover plate 1; a first return spring 3 installed between the trapezoidal blocks 2 and the first cover plate 1; two trapezoidal blocks 2 form a group to fix the push rods 5. When the push rods 5 rotate, the inclined surface of the trapezoidal blocks 2 contacts the push rods 5. Therefore, under the action of the first return spring 3, the trapezoidal blocks 2 can automatically extend and retract so that the push rods 5 can rotate between the two trapezoidal blocks 2 and be clamped, thus realizing the action of connecting the movable end of the hydraulic cylinder 300 with the mold 200. During installation, only the hydraulic cylinder 300 needs to be rotated; during disassembly, only the trapezoidal blocks 2 need to be slid. Both installation and disassembly are convenient and quick.

[0029] The annular plate 6 is rotatably connected to the movable end of the hydraulic cylinder 300, and the push rod 5 is rotatably connected to the annular plate 6. During installation, only the annular plate 6 needs to be rotated, which is more convenient. At the same time, after the push rod 5 is separated from the mold 200, the push rod 5 can be rotated backward to store the push rod 5, making it easy to pass through the mounting plate 17.

[0030] It also includes a pull rod 4 installed on the trapezoidal block 2, the pull rod 4 being slidably connected to the first cover plate 1.

[0031] It also includes: a connecting plate 8 fixedly installed at the fixed end of the hydraulic cylinder 300; a groove 9 formed on the connecting plate 8; and an insert 10 slidably installed on the mounting plate 17.

[0032] It also includes: a second cover plate 13 fixedly installed on the mounting plate 17; a circular plate 12 rotatably installed on the second cover plate 13; and an arc-shaped rod 11 for driving the insertion block 10 to move, the two ends of the arc-shaped rod 11 being rotatably connected to the circular plate 12 and the insertion block 10, respectively.

[0033] It also includes: a limiting hole 16 opened on the mounting plate 17; a plug rod 14 slidably mounted on the circular plate 12; a second return spring 15 installed between the plug rod 14 and the circular plate 12; the cooperation between the plug rod 14 and the limiting hole 16 avoids the circular plate 12 from shifting, thus preventing the mounting plate 17 from being loosely connected to the hydraulic cylinder 300.

[0034] Workflow: Pull the lever 4 to move the trapezoidal block 2 synchronously until the trapezoidal block 2 and the push rod 5 are no longer in contact. Then rotate the annular plate 6 to move the push rod 5 synchronously to the insertion hole, thus separating the hydraulic cylinder 300 from the mold 200. Then rotate the push rod 5 backward to rotate it 90 degrees and pull out the insertion rod 14 from the limit hole 16. Then rotate the circular plate 12 and use the arc rod 11 to take the insertion block 10 out of the groove 9 of the connecting plate 8, thus separating the mounting plate 17 from the fixed end of the hydraulic cylinder 300. Then remove the hydraulic cylinder 300 from the mounting plate 17 to achieve quick disassembly of the hydraulic unit.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
