[0041] The base die assembly is provided with a cone bottom injection slot 410, and the top part of the cone bottom injection slot 410 is provided with a third plug-in part injection slot 411.

[0042] In addition, the inner wall diameter of the first plug-in part injection slot 211 is greater than the outer wall diameter of the first plug-in part injection slot 111 and there is a matching gap, the outer wall diameter of the second plug-in part injection slot 311 is greater than the inner wall diameter of the second plug-in part injection slot, and the inner wall diameter of the third plug-in part injection slot 411 is greater than the inner wall diameter of the third plug-in part injection slot and there is a matching gap.

[0047] It should be noted here that in the present embodiment, the slot wall of each injection groove has a draft angle. The draft angle refers to an angle set in the mold design for easy demolding. This angle usually refers to the angle between the side wall of the mold and the vertical direction. The purpose of designing the draft angle is to reduce the friction between the mold and the product, so that the product can be easily taken out of the mold, while avoiding damaging the surface quality of the product. And the draft angle in the present embodiment is specifically 1° to 2°.

[0048] On the other hand, the oxygen dissolving cone forming mold provided by the present embodiment is used in combination with a vacuum introduction technology to realize the manufacturing of the oxygen dissolving cone, i.e., is applied to the vacuum introduction production of the oxygen dissolving cone.

[0050] Specifically, the detachable plate 130 in the present embodiment covers the flange injection groove 110. During the injection process, raw materials can be injected into the flange injection groove 110 through the injection port. After the flange is solidified and formed, the detachable plate 130 can be detached to take out the flange.

[0051] Wherein, in the present embodiment, the reserved part can form a groove on the surface of the solidified and formed flange to set a sealing rubber strip on the flange.

[0052] In the embodiment, the base 120 comprises a flange annular plate 121, a flange bottom plate 122 and a side plate 123.

The flange bottom plate 122 is provided with a plug-in interface, the flange annular plate 121 is inserted into the plug-in interface, and the outer wall of the flange bottom plate 122 is arranged in an inclined manner from top to bottom. The side plate 123 is sleeved on the outer wall of the flange bottom plate 122 and is clamped and connected with the outer wall of the flange bottom plate 122 through the inclined surface. The outer wall of the flange annular plate 121 and the inner wall of the side plate 123 form a first plug-in part injection slot 111 at the top end of the flange injection slot 110.

[0053] Specifically, in the embodiment, the outer wall of the flange annular plate 121, the top wall of the flange bottom plate 122 and the inner wall of the side plate 123 jointly form the flange injection slot 110, and the outer wall of the flange annular plate 121 and the inner wall of the side plate 123 are both provided with a draft angle. Through the structure of clamping and connecting through the inclined surface, after the flange is solidified and formed, the side plate 123 and the flange bottom plate 122 can be disassembled along the inclined direction of the inclined surface, and then the formed flange is pushed from top to bottom to be disassembled from the outside of the flange annular plate 121, so as to realize the demolding of the flange.

[0054] When demolding, the flange mold assembly 100 can be inverted, that is, the flange annular plate 121 can be moved upward, so as to realize demolding, which is more convenient and labor-saving.

[0055] In the embodiment, the detachable plate 130 is provided with a reserved bolt, so that a screw hole can be formed on the surface of the formed flange. After the flange is solidified and formed, the reserved bolt can be unscrewed to facilitate demolding.

The slot opening inner diameter of the first plug-in part injection slot 111 is greater than the slot opening inner diameter of the flange injection slot 110, which does not affect the demolding of the flange. In addition, the top of the flange after injection molding forms a first plug-in part, and the inner diameter of the first plug-in part is slightly larger than the outer diameter of the first plug-in part, so that the flange can be covered on the first plug-in part, and the first plug-in part is arranged outside the first plug-in part. There is a cooperation gap between the first plug-in part and the first plug-in part for gluing and connecting.

[0058] In the embodiment, the reserved part is a flange steel ball. The flange steel ball has a plurality of arrangements along the extension direction of the flange injection slot 110.

The upper section bottom plate assembly 230 is arranged at the bottom end of the upper section body 220, and the upper section bottom plate assembly 230 forms a second plug-in part injection slot at the bottom end in the upper section injection slot 210.

[0061] Specifically, the upper section injection slot 210 in the embodiment is the same as the upper section structure of the dissolved oxygen cone. When the upper section structure of the dissolved oxygen cone is injection molded, the first plug-in part injection slot 211 can form a first plug-in part on the top end of the upper section structure of the dissolved oxygen cone, which is matched with the bottom end of the flange, and there is a matching gap between the two to facilitate the application of glue for gluing, so as to realize the plugging of the flange and the upper section of the dissolved oxygen cone.

[0062] In the embodiment, the upper section bottom plate assembly 230 includes an upper section annular plate 232 and an upper section bottom plate 231. Please refer to Figure 7 The inner wall of the bottom end of the upper section injection slot 210 is provided with a first mounting slot, the first mounting slot is arranged along the circumference of the upper section injection slot 210, and the bottom surface of the upper section injection slot 210 is provided with a limiting structure 240.

The upper section bottom plate 231 is arranged at the bottom of the upper section body 220, and one end of the upper section bottom plate 231 extends into the upper section injection slot 210 and is arranged in a spaced manner with the upper section annular plate 232 to form a second plug-in part injection slot.

[0063] Specifically, the slot wall of the first mounting slot is arranged obliquely, and the upper section annular plate 232 is arranged in the first mounting slot and is interference-fitted with the obliquely arranged slot wall to realize detachable mounting. The outer wall of the upper section annular plate 232 and the part of the upper section bottom plate 231 located in the upper section injection slot 210 enclose a downwardly extending second plug-in part injection slot, and the second plug-in part injection slot forms a ring-mounted plug-in part at the bottom end of the upper section injection to be connected to the lower section of the dissolved oxygen cone for plugging. When demolding, the upper section bottom plate 231 and the upper section annular plate 232 are sequentially detached from below, so that the upper section of the cone is demolded.

[0064] In the embodiment, the bottom of the upper section body 220 is provided with a plurality of limiting screws, and the plurality of limiting screws are arranged in a spaced manner along the circumference of the upper section body 220 to enclose the limiting structure 240.

The lower section bottom plate 323 is arranged at the bottom end of the lower section body 320 and forms a third plug-in member injection slot at the bottom end of the lower section injection slot 310.

[0067] Specifically, the lower section access member 321 in this embodiment is arranged in the top slot of the lower section injection slot 310, and the inclination angle of the two outer side walls of the lower section access member 321 is smaller than the taper angle of the lower section injection slot 310. Therefore, the lower section access member 321 can be gradually clamped in the slot of the lower section injection slot 310 through the top slot of the lower section injection slot 310.

[0068] The lower section access member 321 forms a second plug-in part injection slot 311 at the top slot of the lower section injection slot 310. After the lower section of the dissolved oxygen cone is injection molded and solidified, an insertion structure with an outer diameter smaller than that of the lower section of the dissolved oxygen cone is formed at the top of the lower section of the dissolved oxygen cone.
