[0004] However, in the aforementioned patent application, the mold used to produce communication base station substrates generally has a positioning post between the upper and lower molds to ensure the accuracy of the fit between the upper and lower molds. However, if it is used for a long time and is not lubricated in time, wear will occur between the positioning post and the upper mold, resulting in a decrease in positioning accuracy, which will affect the normal production of communication base station substrates. Utility Model Content

[0005] The purpose of this utility model is to provide a mold for producing communication base station cover plates, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A mold for producing a cover plate for a communication base station includes a lower mold and an upper mold. A connecting plate is fixedly installed on the upper surface of the upper mold, and a top cover is fixedly installed on the upper surface of the connecting plate. A nozzle is fixedly installed on the upper surface of the top cover. Two positioning posts are inserted near both sides of the upper surface of the lower mold, and the bottom ends of the four positioning posts are fixedly connected to the lower mold. A lubrication mechanism is provided on each of the four positioning posts. A straightening mechanism is provided near the four corners of the outer wall of the lower mold.

[0008] The lubrication mechanism includes an oil reservoir and a movable plate. The oil reservoir is fixedly installed at the top of the positioning column, and the movable plate is movably inserted into the outer wall of the positioning column. A push plate is slidably connected to one side of the oil reservoir.

[0009] Preferably, one end of the movable plate is fixedly connected to the push plate, and two return springs are fixedly connected to the outer wall of the oil storage box, with one end of each return spring fixedly connected to the movable plate.

[0010] A refueling pipe is fixedly connected to the upper surface of the positioning post, and the bottom end of the refueling pipe is fixedly connected to the oil storage box. A pipe cap is fitted onto the upper end of the refueling pipe.

[0011] Preferably, a sponge block is inserted inside the oil storage box, a connecting pipe is fixedly connected to the bottom of the oil storage box, a number of diversion pipes are fixedly connected to the bottom of the connecting pipe, and a number of leakage holes are opened through the outer wall of the positioning column.

[0012] Preferably, the plurality of the leak holes are distributed at equal distances, and the end of the diversion pipe away from the connecting pipe is fixedly inserted into the leak hole.

[0013] Preferably, the correction mechanism includes a limiting plate, which is fixedly connected to the outer wall of the lower mold. A fixing plate is fixedly installed on the outer wall of the limiting plate, and two pressure plates are movably inserted into the limiting plate.

[0014] Preferably, screws are inserted into both sides of the fixing plate, and one end of each screw is fixedly connected to one of the two pressure plates, and a circular plate is fixedly connected to one end of each screw.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, during demolding, the upper mold moves upward along each positioning post and passes through the movable plate, causing the movable plate to be squeezed and moved into the interior of the positioning post. This drives the push plate to move along the interior of the oil storage box, squeezing the sponge block and causing the lubricating oil cup adsorbed on the sponge block to be squeezed out. Under the action of gravity, the oil flows through the connecting pipe into each distribution pipe, flows out through each drain hole, and flows along the outer wall of the positioning post, automatically lubricating the positioning post. Similarly, after the upper mold and lower mold are closed, the positioning post is also automatically lubricated by the movable plate, avoiding insufficient lubrication of the positioning post and friction damage with the upper mold, which would affect the guiding accuracy of the upper and lower molds. This prevents the upper mold and lower mold from shifting when they are closed, thus affecting the yield of the communication base station cover.

[0018] 2. In this utility model, by rotating the nut, the screw is moved, which in turn moves the pressure plate closer to the outer wall of the upper and lower molds. Similarly, another pressure plate moves closer to the outer wall of the upper and lower molds at the same time. The same operation is performed on the other correction mechanisms, which can further correct and align the position between the lower and upper molds to avoid misalignment and affect the production effect.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A mold for producing cover plates for communication base stations, such as Figures 1-4As shown, the mold includes a lower mold 1 and an upper mold 2. A connecting plate 19 is fixedly installed on the upper surface of the upper mold 2. A top cover 3 is fixedly installed on the upper surface of the connecting plate 19. A nozzle 4 is fixedly installed on the upper surface of the top cover 3. Two positioning pins 5 are inserted near both sides of the upper surface of the lower mold 1, and the bottom ends of the four positioning pins 5 are fixedly connected to the lower mold 1. A lubrication mechanism is provided on each of the four positioning pins 5. A straightening mechanism is provided near the four corners of the outer wall of the lower mold 1. The lubrication mechanism includes an oil storage box 12 and a movable plate 14. The oil storage box 12 is fixedly installed at the top of the inside of the positioning pin 5. The movable plate 14 is movably inserted into the outer wall of the positioning pin 5. A push plate 13 is slidably connected to one side of the inside of the oil storage box 12.

[0028] One end of the movable plate 14 is fixedly connected to the push plate 13. Two return springs are fixedly connected to the outer wall of the oil storage box 12, and one end of each return spring is fixedly connected to the movable plate 14. An oil filling pipe 18 is fixedly connected to the upper surface of the positioning column 5, and the bottom end of the oil filling pipe 18 is fixedly connected to the oil storage box 12. A pipe cap is fitted on the upper end of the oil filling pipe 18. The pipe cap is removed from the oil filling pipe 18, and lubricating oil can be added to the oil storage box 12 through the oil filling pipe 18. The added lubricating oil is absorbed and stored by the sponge block 15. When the movable plate 14 is squeezed and moves into the positioning column 5, the two return springs are squeezed and contracted at the same time. After the squeezing of the movable plate 14 is released, the movable plate 14 can be moved to the initial position under the action of the return spring.

[0029] A sponge block 15 is inserted inside the oil storage box 12. A connecting pipe 16 is fixedly connected to the bottom of the oil storage box 12. Several diversion pipes 17 are fixedly connected to the bottom of the connecting pipe 16. Several leakage holes 22 are opened through the outer wall of the positioning column 5. The leakage holes 22 are evenly distributed. The end of the diversion pipe 17 away from the connecting pipe 16 is fixedly inserted into the leakage hole 22.

[0030] In use, the raw material is injected into the mold through the nozzle 4 and cooled, and then the mold is formed to produce the communication base station cover plate. This is existing technology and will not be described in detail.

[0031] After molding, an external cylinder moves the top cover 3 upward, thereby moving the top cover 3, connecting plate 19, and upper mold 2 upward for demolding. As the upper mold 2 moves upward, it moves along each positioning post 5 and passes the movable plate 14, moving along the inclined surface of the movable plate 14. This allows the movable plate 14 to be squeezed and moved into the interior of the positioning posts 5, causing the push plate 13 to move along the interior of the oil storage box 12, squeezing the sponge block 15. This squeezes out the lubricating oil absorbed on the sponge block 15, and under the action of gravity, it flows out through... The fluid is diverted through the connecting pipe 16 into each diversion pipe 17, and finally flows out through each drain hole 22, flowing along the outer wall of the positioning post 5 to automatically lubricate the positioning post 5. Similarly, after the upper mold 2 and the lower mold 1 are closed, the positioning post 5 is also automatically lubricated by the movable plate 14 to avoid insufficient lubrication of the positioning post 5, which could cause friction damage to the upper mold 2 and affect the guiding accuracy of the upper mold 2 and the lower mold 1. This prevents the upper mold 2 and the lower mold 1 from shifting when they are closed, thus affecting the yield of the communication base station cover.

[0032] like Figure 1 and Figure 4 As shown, the correction mechanism includes a limiting plate 6, which is fixedly connected to the outer wall of the lower mold 1. A fixing plate 20 is fixedly installed on the outer wall of the limiting plate 6. Two pressure plates 7 are movably inserted inside the limiting plate 6. Screws 8 are inserted into both sides of the fixing plate 20, and one end of each screw 8 is fixedly connected to the two pressure plates 7. A circular plate 21 is fixedly connected to one end of each screw 8.

[0033] Two positioning rods 9 are inserted into the outer wall of the circular plate 21, and one end of each positioning rod 9 is fixedly connected to the fixed plate 20. A nut 10 is sleeved on the outside of the screw 8. A limiting shell 11 is fixedly installed on the outer wall of the fixed plate 20 and located outside the nut 10. The circular plate 21 moves along the positioning rods 9 following the screw 8, which can limit the movement position of the screw 8. The inner wall of the nut 10 is provided with a thread that matches the screw 8. When the nut 10 rotates inside the limiting shell 11, it can drive the screw 8 to move under the cooperation of the thread.

[0034] Specifically, after the upper mold 2 and the lower mold 1 are closed, the nut 10 is rotated inside the limiting shell 11, causing the screw 8 to move. The circular plate 21 follows the screw 8 and moves along the positioning rod 9, which can limit the movement position of the screw 8. This causes the pressure plate 7 to move closer to the outer wall of the upper mold 2 and the lower mold 1. Similarly, another pressure plate 7 moves closer to the outer wall of the upper mold 2 and the lower mold 1 at the same time. The same operation is performed on the other correction mechanisms to further correct and align the position between the lower mold 1 and the upper mold 2, avoiding misalignment and affecting the production effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
