Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] In one embodiment, such as Figures 1-4 As shown, a mold structure for manufacturing an energy-releasing cartridge includes an inner cylinder 11 and an outer cylinder 12. The outer cylinder 12 is sleeved on the outside of the inner cylinder 11. The outer side of the inner cylinder 11 and the inner side of the outer cylinder 12 are combined to form a molding chamber 13. A conical retaining ring 14 is provided at the bottom end of the molding chamber 13. The conical retaining ring 14 is sleeved on the bottom end of the inner cylinder 11. A wear-resistant ring 16 is sleeved on the outer side of one end of the conical retaining ring 14. The wear-resistant ring 16 is in close contact with the bottom end of the outer cylinder 12. Both the conical retaining ring 14 and the wear-resistant ring 16 are fixedly disposed on the inner cylinder 11. At the upper end of 7, an outer ring 18 is threadedly connected to the outer side of the inner ring 17. A sealing plate 15 is tightly attached to the bottom end of the inner cylinder 11. The sealing plate 15 is fixedly connected to the bottom end of the inner cylinder 11 by several screws. A top cover 19 is threadedly connected to the upper end of the inner cylinder 11. A cover plate 20 is fixedly attached to the upper end of the top cover 19. A guide mechanism is provided at the upper end of the outer cylinder 12 and the cover plate 20 to facilitate the addition of materials into the molding chamber 13. The guide mechanism facilitates the addition of materials into the molding chamber 13 and facilitates the discharge of excess materials.

[0026] The guiding mechanism includes a flow channel 21 and an overflow port 22. The upper end of the outer cylinder 12 is provided with a plurality of overflow ports 22 in a circular array. The upper end of the cover plate 20 is provided with a flow channel 21 at a position corresponding to the overflow port 22. The upper end of the flow channel 21 is symmetrically provided with a handle 23. When adding material to the molding chamber 13, the material can be added into the flow channel 21 so that the material flows into the molding chamber 13 along the flow channel 21. When too much material is added into the molding chamber 13, the material can be discharged through the overflow port 22.

[0027] The outer cylinder 12 is symmetrically provided with mounting grooves, and each mounting groove is fitted with a handle 24. The handle 24 is fixedly connected to the outer cylinder 12 by fastening screws, which facilitates demolding of the outer cylinder 12 during use.

[0028] The inner cylinder 11 has a first mounting groove at one end, and a first sealing ring 25 is fitted in the first mounting groove. The conical retaining ring 14 has a second mounting groove at one end on the outside, and a second sealing ring 26 is fitted in the second mounting groove. The conical retaining ring 14 has a third mounting groove at the other end on the outside, and a third sealing ring 27 is fitted in the third mounting groove. In use, this facilitates the sealing effect at the bottom of the molding chamber 13.

[0029] The molding chamber 13 is shaped like a frustum of a cone. The diameter of the cross section of the molding chamber 13 near the top cover 19 is smaller than the diameter of the cross section near the sealing plate 15. The material inside the molding chamber 13 is polytetrafluoroethylene. In use, the frustum of a cone shape of the molding chamber 13 facilitates demolding. The energy release cartridge is made of polytetrafluoroethylene, which makes the inner cylinder 11 and outer cylinder 12 have smooth surfaces that are easy to demold, clear edges and corners without collapse, and easy to clean.

[0030] Example 2

[0031] like Figures 5-6As shown, the difference from Embodiment 1 is that: a limiting block 29 is symmetrically provided at one end of the outer cylinder 12, and a limiting groove is provided in the middle of one end of the limiting block 29; an outer ring 28 is provided on the outer side of the outer sleeve 18; a rotating rod 30 is hinged at the position corresponding to the lower position of the limiting block 29 at the upper end of the outer sleeve 18; a sliding tube 31 is slidably provided at one end of the rotating rod 30; a sliding plate is slidably provided at one end of the rotating rod 30; a first return spring 32 is provided between the bottom end of the sliding plate and the inner end of the sliding tube 31; the width of the limiting groove is greater than the cross-sectional diameter of the rotating rod 30; limiting posts 33 are symmetrically provided on the sliding tube 31; a stop groove is provided at the upper end of the limiting block 29 corresponding to the position of the limiting post 33; and the upper end of the limiting block 29... A limiting hole is provided at the position corresponding to the sliding tube 31. The cross-sectional diameter of the sliding tube 31 is larger than the cross-sectional diameter of the rotating rod 30. The cross-sectional diameter of the limiting hole is equal to the cross-sectional diameter of the sliding tube 31. Positioning plates 35 are fixed at the upper end of the outer ring 28 and at the positions corresponding to the two sides of the limiting block 29. In use, when it is necessary to make an energy-releasing cartridge, the limiting block 29 is positioned between the two positioning plates 35 to position the outer cylinder 12. Then, the sliding tube 31 is pulled, and the rotating rod 30 is rotated, so that the limiting post 33 is located in the stop groove at the upper end of the limiting block 29. Then, the sliding tube 31 is released, and under the action of the first return spring 32, the outer cylinder 12 is fixed, thereby increasing the sealing effect between the outer cylinder 12 and one end of the conical retaining ring 14.

[0032] Example 3

[0033] like Figures 5-6 As shown, the difference from Embodiment 1 is that: the upper end of the outer ring 18 and the lower end of the limiting block 29 are both provided with a second return spring 34. In use, before installing the outer cylinder 12, the second return spring 34 is fixed to the upper end of the outer ring 18. When the outer cylinder 12 is fixed, the outer cylinder 12 compresses the second return spring 34. When the outer cylinder 12 needs to be demolded, the limiting post 33 is disengaged from the upper end of the limiting block 29. Under the action of the second return spring 34, the outer cylinder 12 is lifted up. Since the molding chamber 13 is set in the shape of a frustum cone, it is convenient to assist the demolding of the outer cylinder 12.

[0034] The above embodiment discloses a mold structure for manufacturing an energy-releasing cartridge. In manufacturing the energy-releasing cartridge, the outer cylinder 12 is assembled on the upper end of the wear-resistant ring 16. Then, the sliding tube 31 is pulled, causing the rotating rod 30 to rotate, so that the limiting post 33 is located in the stop groove at the upper end of the limiting block 29. Then, the sliding tube 31 is released, and under the action of the first return spring 32, the outer cylinder 12 is fixed, thereby increasing the sealing effect between the outer cylinder 12 and one end of the conical retaining ring 14. Then, the upper cover 19 is installed on one end of the inner cylinder 11 through the handle 23. Then, the prepared material is added into the molding chamber 13 through the flow groove 21. After the energy-releasing cartridge is formed, the limiting post 33 is disengaged from the upper end of the limiting block 29, and the outer cylinder 12 is lifted up under the action of the second return spring 34. Since the molding chamber 13 is truncated cone-shaped, it is convenient to assist the demolding of the outer cylinder 12.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
