Description

Technical Field

[0001] The utility model relates to the technical field of cylinder flange production equipment, in particular to cylinder flange production casting equipment. Background Art

[0002] Casting is a processing technology that melts metal into a liquid that meets certain requirements and pours it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. It is widely used. For example, it is widely used in the production of cylinder flanges and parts of mechanical equipment. In addition, the casting mold as a casting carrier, its related technology has long been disclosed, and relevant researchers have been continuously improving the casting mold. For example, the patent document with application number 202022120434.9 discloses that "the utility model can be used to eject the flange upward after the pouring is completed by setting an ejection assembly. The ejection block is used in conjunction with the slot on the lower mold, so that the slot can be blocked during flange casting to prevent leakage of the pouring liquid. The lower end of the ejection block is connected to a connecting plate through a sliding rod, and a spring is provided between the connecting plate and the mounting slot. After the pouring is completed, the ejection block can be driven upward by the elasticity of the spring, so that the ejection block ejects the flange in the lower mold. The operation is simple and convenient, saving time and effort, and greatly improving the production efficiency of the flange."

[0032] Working principle:

[0033] Embodiment 1

[0034] After the fixed casting mold 1 and the movable casting mold 2 are driven to close the mold, the casting cavity is injected through the casting pipe head 4. After the casting is completed, the fixed casting mold 1 and the movable casting mold 2 are separated, and then the electric push rod 8 is started, and the output end of the electric push rod 8 drives the ejector rod 7, so that the ejector rod 7 automatically ejects the workpiece formed in the casting cavity, and the mechanical transmission formed by the combination of the electric push rod 8 and the ejector rod 7 can maintain the ejection operation for a long time, and then, according to the above steps, the operation is repeated;

[0035] During the long-term use of the ejector rod 7, the T-bar 91 inside the elastic pressure-sensing component 9 will reciprocate with the ejector rod 7 under the elastic action of the spring 92 and synchronously transmit the pressure data to the pressure sensor 11, so that the pressure sensor 11 continuously outputs pressure data, and then the degree of wear of the ejector rod 7 can be determined by the curved change of the pressure data. For example, when the pressure data output by the pressure sensor 11 changes significantly, it means that the ejector rod 7 is worn too much and needs to be replaced in time.

[0036] Embodiment 2

[0037] When a failure occurs in the hollow assembly module 5 or a component installed inside the hollow assembly module 5, the hollow assembly module 5 can be removed from the fixed casting mold 1 and the electric push rod 8 can be removed from the hollow module body 51 by removing the second screw between the hollow module body 51 and the fixed casting mold 1, the first screw between the hollow module body 51 and the sealing cover 52, and the third screw between the support frame and the hollow module body 51, thereby fully meeting the needs of convenient maintenance.
