Ejection mechanism for mold opening of finished insulator product

Abstract

The utility model discloses an ejection mechanism for mold opening of an insulator finished product, which comprises an ejection frame for positioning the end part of an insulator and a pushing piece arranged on a forming lower mold, and a driving device connected with the pushing piece is arranged on the forming lower mold. And after the pushing piece pushes the insulator under the action of the driving device to eject the ejection frame out of the forming lower die, the ejection frame drives the insulator to move out of the forming lower die under the action of external force. When the ejection frame moves the insulator out of the forming lower die in the horizontal direction, the pushing piece cannot be attached to the connecting shaft of the insulator to move together, that is, only the two ends of the insulator are fixed to the ejection frame, and an umbrella cover of the insulator cannot make contact with the pushing piece; the problem that the umbrella cover deforms due to the fact that the pushing piece acts on the umbrella cover during horizontal movement is effectively solved.

Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of ejection mechanisms for insulator finished product mold opening. BACKGROUND

[0002] The existing ejection mechanism for insulator finished product mold opening includes a ejection frame fitted on a lower mold for forming a silicone rubber insulator, a ejection beam is fixedly installed on the ejection frame for supporting the insulator, and when the insulator is to be removed from the lower mold for forming, the ejection frame, the ejection beam and the insulator are removed together from the lower mold for forming. Since the ejection frame and the ejection beam are fixedly connected, after the ejection frame and the ejection beam completely remove the insulator from the lower mold for forming, an external device is used to pull up the insulator. However, the following problems may occur when operating the ejection mechanism:

[0003] Since the ejection beam is always attached to the middle section of the insulator, when the ejection frame removes the insulator from the lower mold for forming, the length of the insulator is relatively long, and the insulator is prone to relative friction with the ejection beam under the action of an external force, which may cause the umbrella cover on the insulator to be deformed, thereby affecting the quality of the insulator. SUMMARY

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides an ejection mechanism for insulator finished product mold opening.

[0005] To solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

[0006] An ejection mechanism for insulator finished product mold opening includes a ejection frame for positioning the end of the insulator, and a pushing member provided on a lower mold for forming. The lower mold for forming is provided with a driving device connected with the pushing member. The pushing member pushes the insulator under the action of the driving device to eject the ejection frame from the lower mold for forming. Then, the ejection frame drives the insulator to move out of the lower mold for forming under the action of an external force.

[0007] Preferably, the pushing member is a top block matched with the outer periphery of the connecting shaft of the insulator.

[0008] Preferably, the driving device is a telescopic cylinder provided on the lower mold for forming, and the top block is connected to the telescopic cylinder.

[0009] Preferably, a locking device is provided between the ejection frame and the lower mold for forming.

[0010] Preferably, the locking device includes an insertion block provided on the lower mold for forming and a movable slot provided on the ejection frame. An elastic tensioning structure is provided in the movable slot, and the elastic tensioning structure can abut the insertion block in the movable slot.

[0011] The elastic tensioning structure preferably comprises springs symmetrically arranged in the movable groove, and a pressing block is connected to each spring and is pressed against the plug under the action of the spring.

[0012] The utility model has the advantages of:

[0013] When the ejection frame moves the insulator along the horizontal direction out of the lower mold, the pushing member does not move together with the connecting shaft of the insulator, that is, only the two end portions of the insulator are fixed on the ejection frame, and the umbrella cover of the insulator does not contact the pushing member, effectively preventing the problem that the pushing member acts on the umbrella cover to cause deformation of the umbrella cover during horizontal movement.

Figures 2-3 The structure diagram of the ejection frame 2 being locked on the forming lower die 3 by the locking device, and only the cooperation between the forming lower die 3 and the ejection frame 2 is shown in the figure, since the design emphasis of the present application is the working principle of moving the insulator 1 out of the forming lower die 3 by the ejection frame 2 after the forming upper die is opened, so the forming upper die is not shown in the figure.

[0033] As shown in FIG. Figure 2 The end of the connecting shaft 1-1 of the insulator 1 is positioned on the ejection frame 2 by the axial positioning device 1-3 (the axial positioning device can refer to CN106426827A), and the pusher 4 is attached to the middle segment position of the connecting shaft 1-1 of the insulator 1, and the outer peripheral curvature of the pusher 4 is matched with the connecting shaft 1-1, when the insulator 1 is formed, the driving device 5 is started, since the pusher 4 is connected to the driving device 5, so the driving device 5 pushes the pusher 4 to move upward, the pusher 4 in turn pushes the connecting shaft 1-1 of the insulator 1 to move upward, according to the principle of force transmission, the insulator 1 drives the ejection frame 2 to move out of the forming lower die 3 (as shown in FIG. Figure 5 Figure 1 The structure diagram of the pusher 4 moving upward by 30cm, and then the ejection frame 2 and the insulator 1 are moved out of the forming lower die 3 along the horizontal direction by the external equipment, in the moving-out process, the pusher 4 is located in the forming lower die 3, and will not move together with the ejection frame 2.
