In this embodiment, by providing a guide rod 25, the telescopic plate 24 can move up and down along the guide rod 25 as the upper cylinder 47 works, thereby ultimately avoiding positional deviation of the telescopic plate 24 when it moves, thereby affecting the final position of the elliptical push block 6 pressed into the small circular hole groove 19, and affecting the molding effect.

[0030] Preferably, in order to adjust the distance between the forming roller 2 and the elliptical telescopic table 7, a positioning frame 38 is fixed on the frame 1, and an adjusting rod 39 is threadedly connected to the positioning frame 38. A connecting seat 40 is arranged at one end of the adjusting rod 39, and a clamping plate 42 is fixed to the upper and lower parts of the connecting seat 40 by a locking screw 41, and a rotating shaft 43 is clamped between the two clamping plates 42, and a forming roller 2 is fixed outside the rotating shaft 43. In this embodiment, by adjusting the distance between the forming roller 2 and the elliptical telescopic table 7, the forming roller 2 can be formed for products of different thicknesses, thereby finally improving the versatility of the mold. When working, the horizontal moving distance of the forming roller 2 is adjusted by rotating the adjusting rod 39 as required to ensure that the elliptical shell 16 is installed on the elliptical telescopic table 7, and when clamped, the forming roller 2 needs to be moved to a position that fits the elliptical shell 16.

[0031] Preferably, in order to facilitate adjustment, an adjusting hand wheel 45 is fixed to the other end of the adjusting rod 39. In this embodiment, the adjusting hand wheel 45 is provided to facilitate hand-gripping operation.

[0032] The specific working principle of this structure is as follows: In the initial state, the annular block 1 9, the annular block 2 11, the annular block 3 13 and the annular block 4 15 are in the following state: Figure 3 The state of the large fan-shaped block 1 8, the large fan-shaped block 2 10, the large fan-shaped block 3 12, and the large fan-shaped block 4 14 is as follows Figure 3 Located at the outer side of the annular block, the elliptical push block 6 is located above to press down, the elliptical shell 16 to be formed is placed outside the elliptical telescopic table 7, and then the cylinder 47 above is driven to work, pushing the elliptical push block 6 down and inserting it into the small circular hole groove 19, which will push the surrounding annular blocks 1 9, 11, 13 and 15 to move outward. At this time, the spring 1 22 under the annular block 1 9, 11, 13 and 15 is squeezed, and at the same time, as the elliptical push block 6 continues to move downward , the annular block 1 9, the annular block 2 11, the annular block 3 13 and the annular block 4 15 continue to move outward, so that the push strip 23 is inserted into the positioning groove 801. At this time, as the elliptical push block 6 continues to move downward, the large fan-shaped block 1 8, the large fan-shaped block 2 10, the large fan-shaped block 3 12, and the large fan-shaped block 4 14 are synchronously driven outward until the elliptical push block 6 can no longer move downward, and the large fan-shaped block 1 8, the annular block 1 9, the large fan-shaped block 2 10, the annular block 2 11, the large fan-shaped block 3 12, the annular block 3 13, the large fan-shaped block 4 14, and the annular block 4 15 are pushed to the position as shown in the figure. Fig.10As shown, at this time, the elliptical shell 16 can be clamped, and then the motor 301 below is driven to work, driving the turntable 302 to rotate, and synchronously driving the elliptical telescopic platform 7 to rotate, so that the elliptical shell 16 rotates 360 degrees. At this time, the elliptical shell 16 rotates. Due to the previous work, it is required to adjust the horizontal movement distance of the forming roller 2 by rotating the adjusting rod 39 to ensure that the elliptical shell 16 is installed on the elliptical telescopic platform 7, and when it is clamped, the forming roller 2 needs to be moved to a position that fits the elliptical shell 16. At this time, the elliptical shell 16 is against the forming roller 2 on the side. At this time, the bending pressure ring 46 on the forming roller 2 will be used to squeeze the side of the elliptical shell 16 (and in the later stage, in order to facilitate the automatic adjustment of the horizontal distance of the forming roller 2, the adjusting rod 39 can be replaced with a light rod, and one side of the light rod is driven by a cylinder to move the light rod horizontally for automatic adjustment), and finally the forming operation of the upper and lower grooves of the elliptical shell 16 is realized. After the forming is completed, the electric Machine 301 stops working, and the upper cylinder 47 returns to allow the elliptical push block 6 to move up. Then, under the action of spring 1 22, large fan-shaped block 1 8, annular block 1 9, large fan-shaped block 2 10, annular block 2 11, large fan-shaped block 3 12, annular block 3 13, large fan-shaped block 4 14, and annular block 4 15 are quickly reset. At this time, the elliptical shell 16 is not clamped, and the elliptical shell 16 is quickly demoulded. Therefore, through this structural setting, the automatic molding and positioning operation of the elliptical shell 16 can be realized, and rapid demoulding can be realized in the later stage, thereby reducing labor costs. In addition, the labor only needs to place the elliptical shell 16 outside the elliptical telescopic table 7, and no handholding is required in the later stage, thereby further improving the safety of processing and improving the overall work efficiency.

[0033] Example 2

[0034] See also Figure 7-8 As shown, a shell elliptical forming mold disclosed in this embodiment is preferably provided. In order to facilitate the replacement of the elliptical telescopic table 7 above, a positioning plate 27 is fixed on the turntable 302, a positioning groove 28 is provided on the positioning plate 27, a clamp seat is placed on the positioning plate 27, the clamp seat includes a left C-type clamp 29 and a right C-type clamp 30 hinged to each other, a T-shaped support 32 is fixed at the bottom of the base 3, the notches of the two left C-type clamps 29 and the right C-type clamp 30 cooperate to form a clamp 31 for clamping the T-shaped support 32, the left C-type clamp 29 and the right C-type clamp 30 are provided to form a clamp 31 for clamping the T-shaped support 32, and the left C-type clamp 29 and the right C-type clamp 30 are provided to form a clamp 31 for clamping the T-shaped support 32. There is a positioning screw 33 passing through each of the C-shaped clamps 30, and the positioning screw 33 passes through the corresponding C-shaped clamp in turn and is threadedly connected to the positioning plate 27. In this embodiment, the above-mentioned structural arrangement can be used to replace elliptical telescopic platforms 7 of different sizes. In the later stage, it is only necessary to unscrew the positioning screw 33, and then insert the T-shaped support 32 below the elliptical telescopic platform 7 of the required size into the clamping opening 31, and then tighten the positioning screw 33. The elliptical telescopic platforms 7 of different sizes only have different sizes of the elliptical telescopic platforms 7, and the sizes of the T-shaped support 32 below can be consistent.

[0035] Example 3

[0036] See also Fig. 9 As shown, the embodiment discloses an elliptical forming mold for a shell. Preferably, in order to play a guiding role and a reset and rebound role, the elliptical push block 6 is fixed on a fixed plate 34. A guide rod 2 35 is provided on both sides above the fixed plate 34. A mounting plate 36 is connected to the lower part of the pressure plate 5. The guide rod 2 35 is movably inserted into the mounting plate 36, and a spring 2 37 with one end abutting against the bottom of the mounting plate 36 and the other end abutting against the top surface of the fixed plate 34 is connected to the outer sleeve of the guide rod 25. In this structure, the upper part of the elliptical push block 6 is connected to the pressure plate 5 in an elastic connection manner. As the pressure plate 5 moves downward, the elliptical push block 6 is driven downward until the elliptical push block 6 moves and is inserted into the small circular hole groove 19. Then, after continuing to move downward, it will first push the four annular blocks to move outward. When the push strip 23 pushes against the large fan-shaped block, it simultaneously drives the large fan-shaped block to move outward until it becomes Fig.10 Because the elliptical push block 6 has elasticity only on the upper side, when the pressing plate 5 moves up in the later stage, the elliptical push block 6 can rebound quickly, thereby further improving the demoulding effect.

Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
