Description

Technical Field

[0001] This utility model relates to the field of centralizer mold technology, specifically a multi-hole centralizer mold. Background Technology

[0002] Cable straighteners are devices that play an important role in fields such as oil extraction. They are mainly used to straighten cables in oil wells, ensuring that the cables are in the correct position. Their structure is usually adapted to the environment of oil wells. Through specific design, they hold the cables in place, preventing them from shifting or sticking to the well wall downhole. This helps ensure the normal operation of cable-related equipment in various downhole operations, such as logging instruments, which can work smoothly along the cable, thus improving the accuracy, safety, and efficiency of downhole operations.

[0003] In the existing technology, centralizers are usually made of polymer materials such as nylon, which have good wear resistance and corrosion resistance, and can meet the requirements of centralizers in different environments. Generally speaking, centralizers are produced by injection molding. However, injection molds are usually difficult to change, and a set of molds can only injection mold a single style of centralizer, which is difficult to meet the needs of producing different centralizers.

[0004] Therefore, this utility model provides a multi-hole centralizer mold to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a multi-hole centralizer mold, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a first membrane shell 1, a second membrane shell 2 on one side of the first membrane shell 1, a first mounting groove 3 on the side of the first membrane shell 1 near the second membrane shell 2, a first limiting post 4 fixedly connected inside the first mounting groove 3, a punch 5 fitted on the side surface of the first limiting post 4, the side surface of the punch 5 fitting against the inner wall of the first mounting groove 3, a second mounting groove 6 and a groove 14 respectively on the side of the second membrane shell 2 near the first membrane shell 1, a second limiting post 7 fixedly connected inside the second mounting groove 6, a die 8 fitted on the side surface of the second limiting post 7, the side surface of the die 8 fitting against the inner wall of the second mounting groove 6, the groove 14 communicating with the second mounting groove 6, a boss 13 adapted to the groove 14 on the side of the first membrane shell 1 near the second membrane shell 2, and a baffle 25 fixedly connected to the top of the second membrane shell 2.

[0026] During the injection molding production of the centralizer, the matching punch 5 and die 8 need to be installed inside the first diaphragm housing 1 and the second diaphragm housing 2, respectively. The setting of the first limiting post 4 and the second limiting post 7 can provide a limiting effect for the punch 5 and die 8, so that the punch 5 and die 8 can be accurately installed inside the first mounting groove 3 and the second mounting groove 6. At the same time, it can also ensure the stability of the punch 5 and die 8. After the punch 5 and die 8 are installed, the first diaphragm housing 1 and the second diaphragm housing 2 can be merged together to carry out the injection molding production of the centralizer. The setting of the baffle 25 can reduce the possibility of liquid raw material splashing.

[0027] Furthermore, to facilitate the replacement of punch 5 by the staff, such as... Figure 2 , Figure 3 and Figure 6 As shown, an auxiliary groove 9 is provided on one side of the punch 5. Several rotating shafts are fixedly connected inside the auxiliary groove 9. A roller 10 is rotatably connected to the side surface of each rotating shaft. The side surface of the roller 10 is in contact with the inner wall of one side of the first mounting groove 3.

[0028] When replacing the punch 5, the punch 5 inside the first mounting slot 3 needs to be removed first. During the movement of the punch 5, the roller 10 will also rotate on the shaft due to the influence of friction to assist the movement of the punch 5, effectively reducing the friction when the punch 5 moves, thus making it easier for the staff to replace the punch 5.

[0029] Furthermore, to facilitate the replacement of die 8 by staff, such as... Figure 1 , Figure 2 and Figure 4 As shown, a bracket 21 is fixedly connected to the side of the second membrane shell 2 away from the first membrane shell 1. A push rod 22 is slidably connected to the bracket 21. One end of the push rod 22 extends into the interior of the second mounting groove 6. A limit ring 23 is fixedly connected to the side surface of the push rod 22. A spring 24 is sleeved on the side surface of the push rod 22.

[0030] One end of the spring 24 is fixedly connected to one side of the limiting ring 23, and the other end of the spring 24 is fixedly connected to the side of the second diaphragm 2 away from the first diaphragm 1. The side of the limiting ring 23 away from the spring 24 is in contact with the side of the bracket 21.

[0031] When replacing the die 8, the die 8 inside the current second mounting slot 6 must be removed first. At this time, simply press the push rod 22. The end of the push rod 22 that extends into the second mounting slot 6 can push the die 8 out of the second mounting slot 6, so that the staff can replace the die 8. When the push rod 22 is pressed and moved, the limiting ring 23 can move synchronously and compress the spring 24. After the pressure of the push rod 22 is released, the spring 24 can drive the reset push rod 22 through the limiting ring 23.

[0032] It should be noted that, in order to improve the stability of the first membrane shell 1 and the second membrane shell 2 after they are bonded together, such as... Figure 1 , Figure 2 and Figure 5 As shown, a calibration column 11 and a calibration strip 12 are fixedly connected to the side of the second membrane shell 2 near the first membrane shell 1, a calibration hole 16 adapted to the calibration column 11 is provided on the first membrane shell 1, and a calibration groove 15 adapted to the calibration strip 12 is provided on the side of the first membrane shell 1 near the second membrane shell 2.

[0033] A second fixing block 20 is provided on one side of the first membrane shell 1, and a first fixing block 17 is provided on one side of the second membrane shell 2. A screw 18 is rotatably connected inside the first fixing block 17, and a nut 19 is screwed onto the screw 18.

[0034] During mold closing, the alignment pin 11 and alignment strip 12 need to be inserted into the alignment hole 16 and alignment groove 15 respectively. The alignment pin 11 and alignment strip 12 are set to improve the accuracy of mold closing. After the mold closing is completed, the screw 18 can be rotated so that the screw 18 enters the second fixing block 20. Then, the nut 19 is rotated so that the nut 19 is tightly attached to the second fixing block 20, so that the first membrane shell 1 and the second membrane shell 2 are tightly attached together, which improves the stability of the first membrane shell 1 and the second membrane shell 2 after they are attached together.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
