[0002] In modern downhole oil pipes, sealing joints are required to connect with the oil pipes. Existing sealing joints are mostly made of metal materials and are processed by casting. In order to ensure the sealing performance, the sealing joints are mainly formed by one-piece casting. In modern one-piece casting, it is mainly achieved through molds.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: in the modern sealing joint processing process, the sealing joint is mainly formed by die-casting construction means. The existing die-casting construction mold mainly adopts a single casting method. After the die casting is completed, the material is cooled before the next die casting. This method is inefficient. At the same time, the temperature of the molten metal at the processing head position is low, which easily leads to a decrease in the casting quality of the sealing joint.

[0022] In view of the above problems, the present application discloses a molding device for processing sealing joints. The device uses a processing machine 1 as a main body for support and installation. The rotary conveyor table 2 on the processing machine 1 performs a rotary motion, so that the rotary conveyor table 2 drives a plurality of molding molds 3 to rotate, so that the molding molds 3 are staggered in various stations. The plurality of molding molds 3 are at least 6 molding molds 3, which move alternately in working stations in different states. The rotary conveyor table is controlled to rotate by a dividing mechanism 10. The dividing mechanism 10 controls the single rotation angle of the rotary conveyor table to be the included angle of adjacent molding molds 3. Specifically, the rotary conveyor table 2 is divided into a mold opening station, a mold closing station, a die-casting station and at least one cooling station. The plurality of molding molds 3 adopt an upper and lower mold opening structure. When the mold rotates to the mold opening station, the cast pipe fittings are The material is unloaded, and then the forming mold 3 is driven to move to the mold closing station through the rotary conveyor table 2, and the upper mold of the forming mold 3 is installed on the lower mold, and then the rotary conveyor table 2 is used to continue to drive the forming mold 3 to move to the die-casting station. A support seat 4 is provided on the upper part of the rotary conveyor table 2 corresponding to the die-casting station processing machine 1, and one side of the support seat 4 is connected to a pressure feeding structure 5. The pressure feeding structure 5 corresponds to the forming mold 3 located at the die-casting station, and the metal melt is injected into the forming mold 3 by pressure. After the die-casting is completed, the rotary conveyor table continues to rotate and move to the cooling station, and then die-casting is carried out through the forming mold 3. The cooling system on the forming mold 3 is used to cool the die-casting sealing joint, and at the same time, the next forming mold 3 moves to the die-casting station, thereby completing the cycle of the die-casting work;

[0023] Furthermore, the lower mold of the molding mold 3 is fixed on the rotary conveying platform 2, and the molding mold 3 is provided with a docking feed nozzle 6, and the docking feed nozzle 6 is provided with a telescopic feed interface 7; the pressure feeding structure 5 is provided with a liquid injection nozzle 8, and the liquid injection nozzle 8 and the telescopic feed interface 7 of the docking feed nozzle 6 adopt a transition fit, and a heating couple 9 is provided on one side of the liquid injection nozzle 8;

[0024] During the specific implementation process, in order to improve the die-casting efficiency of the forming mold 3 and to avoid the problem of temperature reduction of the molten metal on one side of the pressure feeding structure 5 during the die-casting pause stage, on the one hand, the next forming mold 3 is quickly rotated to the die-casting station corresponding to the pressure feeding structure 5 through the rotary conveyor table 2, and then the telescopic feeding interface 7 on the docking feed nozzle 6 is used to push back and insert the liquid injection nozzle 8 set on the pressure feeding structure 5, so that the liquid injection nozzle 8 is connected with the docking feed nozzle 6, and the forming mold 3 is connected with the pressure feeding structure 5, which facilitates the completion of die-casting. On the other hand, the heating couple 9 at the position of the liquid injection nozzle 8 is used to heat the molten metal at the position of the liquid injection nozzle 8, so as to maintain the temperature and fluidity of the molten metal and ensure the quality of the sealing joint during the casting process.

[0025] As a preferred embodiment, further, a reverse thrust spring 11 is arranged between the telescopic feed interface 7 and the docking feed nozzle 6, and a double-sided slope angle is provided at the end of the telescopic feed interface 7, and a corresponding bevel groove with a matching angle is provided on the corresponding injection nozzle 8. When the docking feed nozzle 6 rotates toward the side of the injection nozzle 8, due to the pushing-away effect of the injection nozzle, the telescopic feed interface 7 on the docking feed nozzle 6 is pushed back under the matching action of the slope angle and the bevel groove. Under the pushing-back action of the telescopic feed interface 7, the telescopic feed interface 7 and the injection nozzle 8 are mutually connected, thereby completing the molding mold 3 and the pressure feeding structure 5. After the die-casting is completed, the rotary conveying table drives the molding mold 3 to rotate away from the side of the pressure feeding structure 5, and the double-sided slope angle on the docking feed nozzle 6 and the bevel groove of the injection nozzle 8 are staggered and separated, thereby pushing the docking feed nozzle 6 back again.

[0026] As a preferred solution, further, control valves are provided on both the docking feed nozzle 6 and the injection nozzle 8. After the docking feed nozzle 6 and the injection nozzle 8 are engaged with each other, the control valves of the two are opened, otherwise the control valves are in a closed state to avoid the control valves.

[0027] As a preferred solution, further, a plurality of cooling systems are arranged on the plurality of molding dies, and the plurality of cooling systems cool the inside of the molding dies 3 .

[0028] As a preferred solution, further, the outside of the heating couple 9 is wrapped with an insulation sleeve, and a detection point is set on one side of the heating couple 9, and a temperature detector 12 is set on the detection point. While the insulation sleeve is used to wrap and protect the heating couple 9, the heat loss of the heating couple 9 is prevented, and then the internal metal melt flow at the position of the injection nozzle 8 is detected by using the temperature detector 12 at the detection point.

[0029] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the pressure feeding structure 5 includes a feeding pipe 501, which is connected to the injection nozzle 8, a feeding hopper 502 is connected to one side of the feeding pipe 501, and a die-cast feeding piston rod 503 is axially mounted in the feeding pipe 501;

[0030] In the specific implementation process, molten metal is added to the feeding pipe 501 through the feeding hopper 502. After the molten metal enters the feeding pipe 501, the die-casting feeding piston rod 503 pushes the molten metal to run to the side of the injection nozzle 8, and is injected into the molding mold 3 from the injection nozzle 8 under pressure.

[0031] From the above, it can be generally known that the molding equipment for processing sealing joints adopts a rotary conveyor table to carry multiple molding molds 3, and the molding molds 3 are circulated between the workstations of the rotary conveyor table. The docking feed nozzle 6 with a telescopic feed interface 7 and the injection nozzle 8 are used to complete automatic docking, thereby completing the die-casting work of the sealing joint, and the docking of the molding mold 3 and the pressure feeding structure 5 is quickly switched by rotating work, thereby quickly completing the switching of the molding mold 3, and the heating couple 9 on the injection nozzle 8 is used to heat and keep the metal molten flow warm, so that the sealing joint molding efficiency is higher and the quality is better.
