DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a plastic mold stamping device, including a support frame 1, an upper die head 3 and a lower die head 4 are installed in the support frame 1, a first push plate 9 is elastically matched on the circumferential side of the upper die head 3, a plurality of pressing plates 6 are fixed on the side of the first push plate 9, a second push plate 10 is elastically matched in the lower die head 4, a limiting plate 12 is installed in the lower die head 4, a plurality of push rods 13 are fixed on the second push plate 10, the push rods 13 correspond to the pressing plates 6, and a heating plate 14 is fixed in the upper die head 3.

[0023] In this embodiment, an electric cylinder 2 is fixed on the support frame 1, and the output end of the electric cylinder 2 is fixedly connected to the upper die head 3. A connecting plate 5 is fixed on the upper die head 3. A plurality of first springs 7 are fixed between the connecting plate 5 and the first push plate 9. The first push plate 9 is a circular structure, and the upper die head 3 is located on the relatively inner side of the first push plate 9.

[0024] Specifically, after the upper die head 3 completes stamping, the upper die head 3 is reset, and the first spring 7 rebounds, thereby squeezing and pushing the first push plate 9, so that the first push plate 9 pushes the plastic part downward, which facilitates the demoulding of the plastic part and the upper die head 3.

[0025] The lower die head 4 is fixedly connected to the support frame 1, the limit plate 12 is fixed in the lower die head 4, and the limit plate 12 is a circular structure, the second push plate 10 is located on the upper side of the limit plate 12, and a plurality of grooves 11 are opened in the lower die head 4, the grooves 11 correspond to the push rod 13, the push rod 13 is a U-shaped structure, one end of the push rod 13 is fixedly connected to the second push plate 10, and a plurality of second springs 8 are fixed between the second push plate 10 and the lower die head 4.

[0026] Specifically, after stamping is completed, the upper die head 3 no longer extrude the plastic part, and the second spring 8 rebounds, thereby pushing the second push plate 10 upward, so that the second push plate 10 pushes the plastic part out, thereby facilitating demoulding of the plastic part and the lower die head 4.

[0027] The working process is to place the stamped plastic part on the lower die head 4, and then start the electric cylinder 2, so that the electric cylinder 2 drives the upper die head 3 to move downward, and the pressure plate 6 presses the push rod 13 downward, so that the push rod 13 drives the second push plate 10 to move downward, so that the second push plate 10 contacts the limit plate 12. At this time, the upper die head 3 contacts the plastic part and can be stamped downward. At the same time, the heating plate 14 is heated to soften the plastic part, thereby facilitating stamping. After the stamping is completed, the upper die head 3 is reset. At this time, the first spring 7 rebounds, thereby squeezing and pushing the first push plate 9, so that the first push plate 9 pushes the plastic part downward, which can facilitate the demoulding of the plastic part from the upper die head 3. The upper die head 3 drives the pressure plate 6 away from the push rod 13. At this time, the push rod 13 is no longer limited, so the second spring 8 rebounds to push the second push plate 10 upward, so that the second push plate 10 pushes the plastic part out, thereby facilitating the demoulding of the plastic part from the lower die head 4.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
