Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, in particular to a die-casting equipment which is convenient for demoulding. Background Art

[0002] Die casting equipment, also known as die casting machine, is a machine used for pressure casting. It includes two types: hot press chamber and cold press chamber. Later, they were divided into two types: vertical and horizontal. [1] The die casting machine hydraulically injects molten metal into the mold under pressure and cools it into shape. After the mold is opened, a solid metal casting can be obtained. It was originally used for die casting lead type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, die casting technology has achieved extremely rapid development.

[0003] For example, the utility model with application number CN201921534268.8 discloses an electric clamp-type cold cutting flying saw machine, which is suitable for an electric clamp-type cold cutting flying saw machine. Through the driving gear, the driven gear, the No. 1 motor, the No. 1 flying saw gear and the No. 2 flying saw gear, the flying saw gear can be flexibly moved up and down, and the quantitative flying saw is realized by utilizing the interval between the No. 1 flying saw gear and the No. 2 flying saw gear, thereby improving the mass production and flexibility of an electric clamp-type cold cutting flying saw machine. However, similar to the cold cutting flying saw machine in the above-mentioned document, there is no corresponding structure to assist the saw machine to work while stably displacing. When the equipment is operating, it does not have a structural setting for automatic feeding, and is lacking in overall efficiency and practicality.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a die-casting device that is easy to demould is proposed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a die-casting device that is easy to demold, comprising a protective frame group and a demolding buffer assembly, wherein an injection assembly is installed inside the protective frame group, and one side of the injection assembly is connected to the die-casting assembly, the demolding buffer assembly is installed on the side of the die-casting assembly away from the injection assembly, and a stabilizing cross frame is installed on the top of the demolding buffer assembly, the demolding buffer assembly comprises a support frame, a buffer frame, an ejection hydraulic cylinder and a splitting and closing mold cylinder, the buffer frame is installed on the side of the support frame away from the die-casting assembly, and the ejection hydraulic cylinder is symmetrically installed in the middle section of the buffer frame, and the splitting and closing mold cylinder is symmetrically installed in the upper and lower parts of the support frame on the side close to the die-casting assembly.

[0007] Further, the protective frame group includes a base, a column frame, a protective frame and an auxiliary frame. A column frame is vertically installed on one side of the base, and a protective frame is horizontally installed at the top of the column frame. An auxiliary frame is vertically installed on the side of the base away from the column frame.

[0008] Further, the auxiliary frame is vertically installed on the side of the injection component away from the die-casting component, and the base, the column frame and the protective frame are arranged in a "C" - shaped structure.

[0009] Further, the injection component includes an oil hydraulic control console, a control valve, a boosting accumulator assembly, and a fast injection accumulator assembly. A control valve is connected to one side of the oil hydraulic control console, and a boosting accumulator assembly is connected to the end of the control valve away from the oil hydraulic control console. Moreover, a fast injection accumulator assembly is connected to the end of the boosting accumulator assembly away from the control valve.

[0010] Further, the injection component further includes a charging cylinder and an injection hydraulic cylinder assembly. A charging cylinder is installed on the side of the fast injection accumulator assembly close to the auxiliary frame, and an injection hydraulic cylinder assembly is horizontally installed on the side of the fast injection accumulator assembly away from the charging cylinder.

[0011] Further, the die-casting component includes a frame, tie bars, a fixed die base assembly and a moving die base assembly. Tie bars are symmetrically installed at the upper and lower ends of the frame, and a fixed die base assembly is connected to the end of the tie bar close to the frame.

[0014] The utility model provides a die-casting device which is convenient for demoulding and has the following beneficial effects:

[0015] 1. In this utility model, the output end of the ejection hydraulic cylinder horizontally penetrates through one side of the moving die base assembly. After the fixed die base assembly and the moving die base assembly are closed for docking and die casting is completed, with the assistance of the horizontal telescopic traction of the die separating and closing oil cylinder, the die casting is horizontally pushed out from the inside of the moving die base assembly by using the telescopic property of its own structure, so as to realize demoulding while separating the dies. In addition, while the die separating and closing oil cylinder provides the structural drive for the separation and closing of the moving die base assembly and the fixed die base assembly, it uses its own elastic telescopic property to prevent the moving die base assembly from providing structural buffering when it is displaced while separating the dies, and prevent structural collision with the support frame. In addition, the buffer frame provides structural support for the ejection hydraulic cylinder to ensure that the ejection of the die casting by the ejection hydraulic cylinder maintains sufficient stability.

In addition, the base, column frame and protection frame are combined into a "C"-shaped frame structure, which can effectively protect the die casting assembly and the demoulding buffer assembly without affecting maintenance operations, so that they can avoid being affected by external forces during operation and ensure normal operation. The auxiliary frame provides structural support from the other side of the injection assembly to ensure its structural stability, so as to facilitate the smooth injection of molten material into the inside of the fixed die base assembly and the moving die base assembly.

After the fixed die base assembly 303 and the movable die base assembly 304 are molded and docked and die casting is completed, with the assistance of the horizontal telescopic traction of the mold separation and closing cylinder 404, the die casting is horizontally pushed out from the inside of the movable die base assembly 304 by utilizing the elasticity of its own structure, thereby realizing demolding while separating the mold.

[0024] like Figure 1 , Figure 2 and Figure 4As shown in the figure, the protective frame group 1 includes a base 101, a column frame 102, a protective frame 103 and an auxiliary frame 104. A column frame 102 is vertically installed on one side of the base 101, and a protective frame 103 is horizontally installed at the top of the column frame 102. An auxiliary frame 104 is vertically installed on the side of the base 101 away from the column frame 102.
