Technical Field

[0001] The utility model relates to the technical field of hydroexpansion machines, in particular to a demoulding mechanism of a hydroexpansion machine. Background Technique

[0002] A hydroexpansion machine is a type of internal high-pressure forming technology. Hydroexpansion is a process in which a metal pipe undergoes high-pressure inside the pipe under a high-pressure sealed state to cause the metal to extend and expand from the inside outwards.

[0003] When processing metal pipes, a hydroexpansion machine is often required. After placing the metal pipe on the mold for processing, it is necessary to remove the metal pipe from the hydroexpansion machine. In the prior art, when taking out the metal pipe from the hydroexpansion machine, the operation is usually carried out inside the frame. Therefore, when taking out the metal pipe, it will be restricted by the internal space of the frame. At the same time, when taking out the metal pipe, some metal pipes will be embedded in the mold under the influence of pressure, making it more laborious to take out the material, which is not convenient for the staff to operate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, the present utility model provides a technical solution for a demoulding mechanism of a hydro-expansion machine: a demoulding mechanism of a hydro-expansion machine, including a base 1, a frame 2 is installed on the top of the base 1, a pressurizing device 3 is installed on the top of the frame 2, and an upper module 4 is arranged on the outer surface of the frame 2. It also includes:

[0024] A demoulding component, which is arranged on the base 1 and is used to take out the metal pipe;

[0025] Among them, the demoulding component includes a hydraulic cylinder 5, the hydraulic cylinder 5 is installed on one side of the base 1, the end of the hydraulic cylinder 5 is installed with a lower module 6, a mold groove 11 is arranged on the top of the lower module 6, a first cavity 7 is opened inside the lower module 6, a first spring 8 and a first fixing ring 9 are sleeved inside the first cavity 7, a push rod 10 is installed in the middle of the first fixing ring 9, a connecting plate 12 is installed at the bottom end of the push rod 10, a chute 13 is opened on the top of the base 1, a movable plate 14 is sleeved inside the base 1, an extrusion member 15 is installed on one side of the movable plate 14, a second cavity 16 is opened inside the base 1, a second spring 17 and a second fixing ring 18 are sleeved inside the second cavity 16, and a push rod 19 is installed in the middle of the second fixing ring 18.

[0026] Through the operation of the hydraulic cylinder 5, it will control the lower module 6 to drive the metal pipe to separate from the frame 2. At the same time, through the cooperation between the connecting plate 12 and the movable plate 14, when the lower module 6 moves to a certain position, it will drive the extrusion member 15 to squeeze the chamfer of the push rod 19, so that the push rod 19 will drive the second fixing ring 18 to move along the inner wall of the second cavity 16. At the same time, through the cooperation between the push rod 19 and the connecting plate 12, it will push the push rod 10 to move upward, and the push rod 10 will push the metal pipe to separate from the mold groove 11, facilitating automatic demoulding.

[0027] As Figure 4 shown, the first spring 8 is elastically supported between the first cavity 7 and the first fixing ring 9, and the end of the push rod 10 passes through the lower module 6 and is flush with the bottom surface of the mold groove 11.

[0028] Through the design of the first spring 8, the first fixing ring 9 has good elastic reset performance. At this time, since the first spring 8 is in a compressed state, a elastic force will be exerted on the first fixing ring 9, so as to drive the push rod 10 to move upward. Therefore, when the lower module 6 resets, the push rod 10 can reset, and at this time, the mold groove 11 can be loaded.

[0029] As Figure 4 shown, one side of the connecting plate 12 is convex, and the connecting plate 12 is slidably matched with the sliding groove 13.

[0030] Through the cooperation between the connecting plate 12 and the sliding groove 13, when the lower module 6 moves, the connecting plate 12 will move along the inside of the sliding groove 13. At the same time, through the cooperation between the connecting plate 12 and the movable plate 14, the extrusion part 15 will be driven to extrude the ejector rod 19, making the ejector rod 19 move upward.

[0031] As Figure 5 shown, a chamfer is provided at the bottom of the ejector rod 19, and the extrusion part 15 is in extrusion contact with the inclined surface of the ejector rod 19.

[0032] Through the cooperation between the extrusion part 15 and the ejector rod 19, when the extrusion part 15 extrudes the inclined surface of the ejector rod 19, the second fixing ring 18 will move along the inner wall of the second cavity 16, so that the ejector rod 19 can move upward.

[0033] As Figure 5 shown, the second spring 17 is elastically supported between the second cavity 16 and the second fixing ring 18, and the top end of the ejector rod 19 is in extrusion contact with the connecting plate 12.

[0034] Through the design of the second spring 17, the second fixing ring 18 has good elastic reset performance. At this time, since the second spring 17 is in a compressed state, a elastic force will be exerted on the second fixing ring 18, so that when the connecting plate 12 releases the extrusion on the movable plate 14, the second spring 17 can drive the ejector rod 19 to reset.

[0035] As Figure 4 、 5 shown, the connecting plate 12 is in extrusion contact with the movable plate 14.

[0036] Through the cooperation between the connecting plate 12 and the movable plate 14, when the connecting plate 12 extrudes the movable plate 14, the extrusion part 15 will extrude the inclined surface of the ejector rod 19 to make the ejector rod 19 move upward, which is convenient to control the extrusion of the ejector rod 19 on the connecting plate 12.

[0037] Working principle:

[0038] After the processing of the metal pipe is completed, at this time, the staff can start the hydraulic cylinder 5. Through the operation of the hydraulic cylinder 5, it will control the lower module 6 to drive the metal pipe to disengage from the frame 2. At the same time, through the cooperation between the connecting plate 12 and the movable plate 14, when the lower module 6 moves to a certain position, it will drive the extruding member 15 to extrude the chamfer of the ejector rod 19, so that the ejector rod 19 will drive the second fixing ring 18 to move along the inner wall of the second cavity 16. At the same time, through the cooperation between the ejector rod 19 and the connecting plate 12, it will push the push rod 10 to move upward, and the push rod 10 will push the metal pipe to separate from the die groove 11. At this time, the metal pipe will be automatically demolded.
