[0043] The utility model will be further described below in conjunction with the drawings and specific embodiments, the illustrative embodiment of the utility model and the description are used to explain the utility model, but not as the limitation of the utility model.

[0044] Embodiment 1

[0045] As Figures 1 to 7 Shown, sealing rod flat shaping mould, the shaping mould is used for the shaping of sealing rod 1;The shaping mould includes upper pressing block 2, lower support block 3;The sealing rod is integrated structure, from below to above in turn is rod tail 4, rod body 5, rod head 6;Rod head is discoid, and the lower end surface of rod tail is circular, and the main body of rod tail is cylindrical, and the diameter of the lower end surface of rod tail is less than the diameter of rod head;The shaping mould still includes positioning base 7, left slider 8, right slider 9;

[0046] The upper end surface of the lower supporting block is provided with a slide 10; the middle of the slide is provided with a rectangular socket 11; the positioning base is a cuboid, the horizontal section of which matches the socket, and the positioning base is inserted into the socket; the upper end surface of the positioning base is provided with two front and back symmetrical placement holes 12, the shape and size of which match the tail of the sealing rod;

[0047] The left slide block and the right slide block are of an integrated structure, both of which are identical in structure and symmetrically arranged on the left and right sides of the positioning base through the elastic components;

[0048] The lower end of the right slide block matches the slide in shape and can move left and right along the slide; the left end surface of the right slide block is provided with two shaping half-slots 13; the lower part of the shaping half-slots is provided with a rectangular notch 14; the upper part of the right side surface of the right slide block is a pushing inclined surface 15 which is inclined to the lower right; the rectangular notch is provided so that there is space for accommodating the positioning base when the opposite end surfaces of the left slide block and the right slide block are in contact;

[0049] When the opposite end surfaces of the left slide block and the right slide block are in contact, the shaping half-slots on the left and right sides form a shaping cavity which matches the rod body and the rod head;

[0050] The upper pressing block is of an integrated structure, and the lower part of the upper pressing block is provided with a guide slot 16; the left and right sides of the guide slot are both provided with a guide inclined surface 17; the guide inclined surfaces on the left and right sides respectively match the pushing inclined surfaces on the left and right sides; the top of the guide slot is provided with two circular rod head shaping slots 18; the upper part of the rod head shaping slots is provided with a through hole 19 which penetrates the upper pressing block;

[0051] When the upper pressing block moves to the lowermost position, the left slide block and the right slide block move relative to each other under the action of the guide slot until they are in contact with each other, at which time the placement hole, the shaping cavity and the rod head shaping slot are coaxial.

[0052] The placement hole, the shaping cavity and the rod head shaping slot all match the part standards of the sealing rod. The slide is a T-shaped slot, and the lower end of the right slide block is also a T-shaped block which matches the slide.

[0053] The elastic component is a return spring (not shown in the figure);

[0054] The rectangular notch is provided with two spring mounting holes A 20, and the positioning base corresponding to the rectangular notch is provided with two spring mounting holes B 21, and the two ends of the return spring are fixedly installed in the opposite spring mounting holes A and spring mounting holes B respectively;

[0055] When the upper pressing block moves to the lowermost position, the left and right return springs are retracted in the corresponding spring mounting holes A and spring mounting holes B; when the upper pressing block moves upward, the return spring resets and elongates, and the left slide block and the right slide block move away from each other.

[0056] A limiting hole 22 is provided on each of the left and right sides of the slide, and a limiting post (not shown in the figure) is provided in the limiting hole.

[0057] The upper end of the limiting post is higher than the bottom surface of the slide rail; the setting of the two limiting posts on the left and right sides can prevent the gap from being too large when the left and right sliders stop moving in opposite directions. Under the limiting action of the limiting posts, when the left and right sliders move in opposite directions and maintain the maximum gap, the vertical upward projection of the upper surface of the left and right sliders can fall into the guide groove.

[0058] Working principle:

[0059] like Figure 8 As shown, in this embodiment, the upper pressure block and the lower support block are installed on the press through the mold frame 23 (the installation can be done using existing technology, and will not be described further here), and the position of the upper pressure block is aligned with the lower support block. The debugging component is installed into the tooling to debug the product shaping position (this debugging process is existing technology, well known to those skilled in the art, and will not be described in detail here). When the shaping mold is debugged to be qualified, the shaping can begin.

[0060] like Figure 9 As shown, in this embodiment, the upper pressure block only needs to be moved up and down by the press to drive the upper pressure block to move up and down. After the part to be shaped is placed, the upper pressure block presses down, and the left and right sliders move towards each other to squeeze and shape the sealing rod (the movement path of the shaping mold component is shown by the red arrow). After the shaping is completed, the upper pressure block moves up under the action of the press, and the left and right sliders move away from each other under the action of the return spring (the movement path of the shaping mold component is shown by the black arrow). At this time, the shaped sealing rod can be taken out, and then a new sealing rod can be placed.

[0061] This invention uses the vertical opening and closing of the equipment to drive the left and right sliders to open and close left and right, thereby achieving product shaping. The operator only needs to load the product, start the press, and remove the product to complete the shaping process in three steps, eliminating the need for manual tooling assembly. At the same time, the number of products shaped per unit time is twice that of the old solution, which greatly improves the shaping efficiency. In addition, this invention adopts an assembly form, which facilitates the subsequent maintenance or replacement of tooling wear and tear, and increases the sustainability of tooling to a certain extent.

[0062] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
