Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to a prefabricated mold for a prefabricated ring main unit. Background Technology
[0002] Ring main units (RNUs), as common power distribution equipment in power systems, are widely used in power substations, distribution stations, and other locations, undertaking functions such as protection, control, and monitoring of power equipment. RNUs are typically installed outdoors and require strong pressure resistance, corrosion resistance, and stability. Therefore, the foundation structure design of RNUs has a significant impact on their service life, stability, and construction efficiency. The foundation prefabricated components of RNUs are manufactured using molds.
[0003] Existing technologies disclose several utility model patents in the field of mold processing. Among them, utility model patent application number CN114603688 A discloses a mold comprising two halves, each half including a mold body, a feed inlet, and a mold groove. The feed inlet is located at the top of the mold body, and the mold groove is located inside the mold body, with the bottom of the feed inlet connected to the mold groove. A movable plate is used in conjunction with a push plate, so that when the two halves of the mold separate, the movement of the push plate scrapes off the residual cement and dust in the mold groove, preventing the residual cement and dust from affecting the subsequent molding of cement precast parts. It also allows for timely cleaning of the cement in the mold groove, preventing the cement from corroding the mold due to prolonged uncleaning or becoming impossible to clean after prolonged solidification. This effectively increases the service life of the mold, eliminates the time required for manual cleaning, reduces the workload of workers, increases the efficiency of mold use and demolding, and reduces the demolding time and workload of workers.
[0004] However, the above method still has the following drawbacks in actual use: although it can clean the inside of the mold and ensure the demolding effect of the mold, most molds do not have a self-locking structure, which means that manual pressing is required for a long time during operation. This not only increases the subsequent operation process, but also affects the overall quality of the preform and reduces the flexibility of the mold. Utility Model Content
[0005] The purpose of this utility model is to provide a prefabricated mold for the foundation of a prefabricated ring main unit, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated mold for a prefabricated ring main unit foundation, comprising a lower mold body, an upper mold body overlapping the upper part of the lower mold body, a positioning structure provided inside the lower mold body, the positioning structure being engaged with the upper mold body, a positioning plate connected to the outer surface of the upper mold body, a locking structure fixedly connected to the outer surface of the lower mold body, a slot provided inside the positioning plate, a beveled edge below the positioning plate, the locking structure being engaged in the slot, the locking structure comprising a sleeve plate, a fixing plate and a spring, a slidably connected inside the sleeve plate, a connecting plate fixedly connected above the beveled plate, and a moving rod fixedly connected to one side of the connecting plate.
[0007] As a further preferred embodiment of this technical solution, the lower mold body has a threaded hole at its bottom and a mold groove at its top.
[0008] As a further preferred embodiment of this technical solution, the positioning structure includes a positioning rod and an auxiliary plate. The positioning rod is fixedly connected above the auxiliary plate and is engaged in the lower mold body. The upper mold body is slidably connected to the outer surface of the positioning rod.
[0009] As a further preferred embodiment of this technical solution, the auxiliary plate is snapped onto the lower mold body, and a mounting plate is fixedly connected to the surface of the auxiliary plate. The mounting plate is provided with bolts, and the mounting plate is threadedly connected to the lower mold body through the bolts.
[0010] As a further preferred embodiment of this technical solution, the sleeve is fixedly connected to the front side of the lower mold body, and the spring is sleeved on the outer surface of the moving rod.
[0011] As a further preferred embodiment of this technical solution, one side of the fixed plate is connected to the movable rod, and the movable rod is slidably connected inside the sleeve.
[0012] As a further preferred embodiment of this technical solution, the fixed plate is connected to the sleeve plate by a spring, and the inclined plate is engaged in the slot.
[0013] This utility model provides a prefabricated mold for the foundation of a prefabricated ring main unit, which has the following advantages:
[0014] (1) By setting a positioning plate, locking structure, slot and bevel, the upper mold body will move closer to the lower mold body when it moves. After the bevel contacts the inclined plate, it will drive the moving rod to slide in the sleeve plate. When the fixed plate moves, it will drive the spring to deform. When the upper mold body and the lower mold body are completely in contact, the bevel will separate from the inclined plate. After the inclined plate is reset, it will be locked in the slot. The mold can achieve automatic locking function between the lower mold body and the upper mold body through the cooperation between the inclined plate, spring and slot, reducing the need for manual pressing, ensuring that the mold remains stable during operation, reducing the size deviation of the preform caused by unstable manual pressing, improving the accuracy and quality of the product, and ensuring the flexibility of the mold.
[0015] (2) By setting a positioning structure and threaded holes, the auxiliary plate is inserted into the lower mold body through the positioning rod. The auxiliary plate will be snapped into the bottom of the lower mold body, and the mounting plate will contact the threaded hole. Then the mounting plate is threaded into the threaded hole through the bolt. The upper mold body is then inserted into the positioning rod, thereby achieving precise alignment of the upper mold body and the lower mold body. Precise alignment ensures the production accuracy of the prefabricated parts, reduces dimensional errors, and improves the product qualification rate. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figure 1 andFigure 4 As shown in this embodiment, a prefabricated mold for a prefabricated ring main unit includes a lower mold body 1, an upper mold body 2 overlapping the lower mold body 1, a positioning structure 5 inside the lower mold body 1, the positioning structure 5 being snapped into the upper mold body 2, a positioning plate 3 connected to the outer surface of the upper mold body 2, a locking structure 6 fixedly connected to the outer surface of the lower mold body 1, a slot 8 inside the positioning plate 3, a bevel 9 below the positioning plate 3, the locking structure 6 being snapped into the slot 8, the locking structure 6 including a sleeve plate 601, a fixing plate 605 and a spring 606, a slidably connected to the sleeve plate 601, a connecting plate 603 fixedly connected above the bevel 602, and a moving rod 604 fixedly connected to one side of the connecting plate 603.
[0023] like Figure 1 and Figure 3 As shown, a threaded hole 7 is provided at the bottom of the lower mold body 1, and a mold groove 4 is provided at the top of the lower mold body 1. The positioning structure 5 includes a positioning rod 501 and an auxiliary plate 502. The positioning rod 501 is fixedly connected to the top of the auxiliary plate 502 and is snapped into the lower mold body 1. The upper mold body 2 is slidably connected to the outer surface of the positioning rod 501. The auxiliary plate 502 is snapped into the bottom of the lower mold body 1. An mounting plate 503 is fixedly connected to the surface of the auxiliary plate 502. A bolt 504 is provided in the mounting plate 503. The mounting plate 503 is threadedly connected to the lower mold body 1 through the bolt 504.
[0024] By setting the mounting plate 503 and bolts 504, when the positioning rod 501 is inserted into the lower mold body 1, the auxiliary plate 502 will overlap the bottom of the lower mold body 1, and then the mounting plate 503 will be threadedly connected to the lower mold body 1 through the bolts 504, so that the positioning structure 5 and the lower mold body 1 can achieve the function of quick assembly, which facilitates the replacement and maintenance of the positioning structure 5 in the future, and ensures the applicability of the mold.
[0025] like Figure 4 As shown, the sleeve plate 601 is fixedly connected to the front of the lower mold body 1, the spring 606 is sleeved on the outer surface of the moving rod 604, one side of the fixed plate 605 is connected to the moving rod 604, the moving rod 604 is slidably connected inside the sleeve plate 601, the fixed plate 605 is connected to the sleeve plate 601 through the spring 606, and the inclined plate 602 is snapped into the slot 8.
[0026] By setting spring 606, when the inclined side 9 contacts the inclined plate 602, it will drive the moving rod 604 to slide within the sleeve 601. When the fixed plate 605 moves, it will cause the spring 606 to deform, so that the spring 606 provides a certain support for the movement of the inclined plate 602. When the inclined plate 602 loses resistance, it will be reset by the spring 606, thus preventing the inclined plate 602 from jamming during movement.
[0027] This utility model provides a prefabricated mold for the foundation of a prefabricated ring main unit. The specific working principle is as follows:
[0028] When the mold is used to produce prefabricated components for the ring main unit, the auxiliary plate 502 can be inserted into the lower mold body 1 through the positioning rod 501. The auxiliary plate 502 will be snapped into the bottom of the lower mold body 1, and the mounting plate 503 will contact the threaded hole 7. Then the mounting plate 503 will be threaded into the threaded hole 7 through the bolt 504. The upper mold body 2 will be inserted into the positioning rod 501. After the material is placed into the mold groove 4, a pushing force will be applied to the upper mold body 2, and the upper mold body 2 will slide on the surface of the positioning rod 501.
[0029] When the upper mold body 2 moves, it will approach the lower mold body 1, and the inclined edge 9 below the positioning plate 3 will contact the inclined plate 602. When the inclined plate 602 is pushed, it will drive the moving rod 604 to slide in the sleeve plate 601. When the fixed plate 605 moves, it will drive the spring 606 to deform. When the upper mold body 2 and the lower mold body 1 are completely in contact, the inclined edge 9 will disengage from the inclined plate 602. When the inclined plate 602 loses resistance, it will be reset by the spring 606. After being reset, the inclined plate 602 will be locked in the slot 8.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
