A lower mold 2 is provided on the operating table 1, a mounting cavity 3 is provided in the middle of the lower mold 2, and a mold cavity 4 is provided in the middle of the lower mold 2; one end of the upper mold 5 is fixedly mounted on one side of the lifting plate 6, and the upper mold 5 is mounted above the lower mold 2; the lifting assembly is mounted on one side of the lifting plate 6, and drives the lifting plate 6 to rise and fall, so that the upper mold 5 descends to extrude the bell-shaped shell raw material placed on the lower mold 2; the ejection assembly is mounted inside the mounting cavity 3, and ejects the bell-shaped shell after extrusion molding inside the mold cavity 4, and the ejection assembly is connected to the lifting plate 6.

[0023] See also Figure 2-Figure 5 The ejection assembly shown in the figure includes a lifting plate 7 arranged inside the mold cavity 4, a lifting rod 8 is fixedly provided on one side of the lifting plate 7, one end of the lifting rod 8 passes through the mold cavity 4 and extends into the interior of the installation cavity 3 and is fixedly connected to the lifting rod 9, both ends of the lifting rod 9 are fixed with a fixing block 10, an insertion cavity 11 is provided in the middle of the fixing block 10, and a receiving cavity 12 is provided on both sides of the inner wall of the insertion cavity 11 and is connected to the receiving cavity 12, a limit block 13 is provided inside the receiving cavity 12 for sliding, and a slope is provided on one side of the limit block 13 , a pull rod 14 is passed through one end of the limit block 13, and the end of the pull rod 14 away from the limit block 13 passes through the fixed block 10 and extends to the outside of the storage cavity 12 and is fixedly connected to the guide rod 15. Both ends of the guide rod 15 are provided with vertical slide grooves 16, and one end of the vertical slide groove 16 is connected to one side of the limit block 13 with an inclined slide groove 17 and a first spring 18 is sleeved on the pull rod 14. Guide components are provided on both sides of the fixed block 10, and a second spring 30 is fixed below the fixed block 10;

[0024] See also Figure 3-Figure 5 The ejection assembly shown in the figure also includes a trapezoidal block 19, a T-shaped plate is fixed on one side of the trapezoidal block 19, a suspension rod 20 is fixed on one side of the T-shaped plate, and the other end of the suspension rod 20 is fixedly connected to the bottom of the lifting plate 6. A through hole 21 connected to the mounting cavity 3 is opened on the lower mold 2 and located below the trapezoidal block 19.

[0025] See also Figure 1 and Figure 2The lifting assembly shown in the figure includes a hydraulic rod 22 fixed to one side of the lifting plate 6, and one end of the hydraulic rod 22 away from the lifting plate 6 is connected to the hydraulic cylinder 23.

[0026] When using the bell-shaped shell forming mold: first, place the bell-shaped shell sheet to be extruded on the lower mold 2, and then start the hydraulic cylinder 23 in the lifting assembly. The start of the hydraulic cylinder 23 can drive the hydraulic rod 22 at the output end to extend, and the hydraulic rod 22 drives the lifting plate 6 to descend. At this time, the lifting plate 6 drives the upper mold 5 on one side to descend. When the upper mold 5 descends, it can extrude the bell-shaped shell sheet placed on the lower mold 2 and extrude it into the mold cavity 4, thereby realizing the extrusion molding of the bell-shaped shell.

[0027] As the lifting plate 6 descends, it can drive the suspension rods 20 at both ends to descend synchronously. The descent of the suspension rods 20 drives the trapezoidal block 19 to descend and insert it into the interior of the installation cavity 3 through the through hole 21. During the continuous descending process of the lifting plate 6, the trapezoidal block 19 is inserted into the insertion cavity 11 provided on the fixed block 10. When the trapezoidal block 19 is inserted into the insertion cavity 11, the oblique sides of the trapezoidal block 19 contact the inclined surfaces on the limit block 13 and squeeze the limit block 13 to move toward the interior of the storage cavity 12. At this time, the first spring 18 is squeezed. After the trapezoidal block 19 passes over the limit block 13 and enters the insertion cavity 11, the first spring 18 resets and pushes the limit block 13 to extend toward the inside of the insertion cavity 11 and is located above the trapezoidal block 19, so as to limit the trapezoidal block 19. When the lifting plate 6 continues to descend, the trapezoidal block 19 presses down on the fixed block 10, driving the lifting rod 9, the lifting rod 8 and the lifting plate 7 to descend, so that the lifting plate 7 can reach the bottom of the mold cavity 4, which is convenient for the lower mold 2 and the upper mold 5 to be closed, and the upper mold 5 enters the mold cavity 4 to press and form the bell-shaped shell sheet.

[0028] After the bell shell is formed, the hydraulic cylinder 23 is started, so that the hydraulic cylinder 23 drives the hydraulic rod 22 to contract. The contraction of the hydraulic rod 22 can drive the lifting plate 6 to rise. The rising of the lifting plate 6 can drive the mold between the upper mold 5 and the lower mold 2 to open the mold, so that the upper mold 5 is pulled out of the mold cavity 4 of the lower mold 2. At this time, the mold opening is completed. At the same time, when the lifting plate 6 rises, it drives the suspension rod 20 and the trapezoidal block 19 to rise. Since the trapezoidal block 19 is inserted into the insertion cavity 11, and the trapezoidal block 19 located in the insertion cavity 11 is limited by the limit block 13, At this time, when the hanging rod 20 drives the trapezoidal block 19 to rise, the trapezoidal block 19 pulls the fixed block 10 to rise, and the fixed block 10 rises and drives the lifting rod 9, the lifting rod 8 and the lifting plate 7 to rise. When the lifting plate 7 rises, the bell-shaped shell formed in the mold cavity 4 can be ejected, and the bell-shaped shell after molding can be discharged. At this time, the staff can remove the ejected bell-shaped shell, and the lifting plate 6 continues to rise. When the fixed block 10 rises and drives the guide rod 15 to rise to one end of the vertical slide 16, the guide rod 15 slides into The vertical chute 16 is inside, and the vertical chute 16 slides into the inclined chute 17. The guide rod 15 moves horizontally while lifting, so that the guide rod 15 pulls the limit block to move inside the storage chamber 12, so that the limit block 13 moves away from the top of the trapezoidal block 19, so that the limit block 13 loses the limit on the trapezoidal block 19. At this time, the lifting plate 6 rises and drives the trapezoidal block 19 to rise through the suspension rod 20, while the fixed block does not move up with the trapezoidal block 19. When the fixed block 10 rises, the second spring 30 causes pulling. When the fixed block 10 is not pulled upward by the trapezoidal block 19, the second spring 30 resets and pulls the fixed block 10 downward, so that the lifting plate 7 is reset into the mold cavity 4. At the same time, the guide rod 15 is drawn from the inclined slide 17 into the vertical slide 16 and detached from the vertical slide 16, realizing the re-reset of the limit block 13. The lifting plate 7 is reset to the mold cavity 4 to facilitate the placement of the bell shell sheet on the lower mold. The reset of the limit block 13 is convenient for limiting the trapezoidal block 19 during the next stamping.

[0029] The device has a simple structure and is convenient for staff to operate and use. By adding an ejection component and a lifting component, the bell-shaped shell formed in the mold cavity 4 can be ejected while the lifting component drives the upper mold 5 to rise, so that the formed bell-shaped shell can be ejected when the upper and lower molds are demolded, avoiding the staff from reaching into the mold cavity 4 to remove the bell-shaped shell, and avoiding the staff from using clamping tools to remove the formed bell-shaped shell, effectively reducing the danger and difficulty of the staff in removing the material, and greatly improving the efficiency of the bell-shaped shell processing.
