Description

Technical Field

[0001] This application relates to the field of mold technology for cable boxes, and particularly to an improved mold for an HZ5-24 cable box. Background Technology

[0002] Safety is an eternal theme in railway transportation. During the operation of railway lines, ensuring railway traffic safety is paramount, especially the safety of the electrical control and turnout interlocking equipment. Currently, the traditional HZ24 series cable boxes used for turnout electric switch machines have several shortcomings. First, the traditional cable boxes lack adequate error-proofing technology for turnout electric switch machine wiring. Defects exist in the connection of cable cores and external wiring of the electric switch machine. During signal engineering construction, maintenance, and troubleshooting, frequent disconnection or interruption of wires can easily lead to incorrect connections of cable cores and external wiring of the electric switch machine, resulting in turnout control and indication circuit malfunctions. Improper handling can easily trigger traffic accidents. Second, for three-phase AC five-wire turnouts with control cables longer than 2km, the distributed capacitance between cable cores poses a safety hazard: the turnout indication relay may not reliably deactivate when X1 is disconnected. Traditional HZ24 cable boxes cannot meet the corresponding wiring requirements.

[0003] Therefore, it is necessary to develop an improved HZ5-24 cable box to solve the problems existing in traditional cable boxes; correspondingly, the existing cable box molds cannot meet the production requirements of the improved cable box.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0024] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0025] According to specific embodiments of this application, such as Figure 1-6 As shown, this application provides an improved mold for an HZ5-24 cable box. The mold includes a box body mold and a box cover mold. The box body mold is used to form the box body of the cable box, and the box cover mold is used to form the box cover of the cable box.

[0026] The box mold includes: The box-shaped cavity plate 2 has a box-shaped cavity groove in its center to form the shape of the box; and multiple positioning grooves 21 are provided around the box-shaped cavity plate 2.

[0027] The core plate 4 has a core component in the center to form the inner cavity of the box. Multiple positioning protrusions 41 are provided around the core plate 4, which are used to be inserted into the positioning grooves 21.

[0028] The core assembly inside the box includes a main core 42, two fixing plate cores 45, and a lead hole core 3; the two fixing plate cores 45 are located on the left and right sides of the main core 42, respectively, and the lead hole core 3 is located on the front side of the main core 42; the lead hole core 3 is used to form lead holes on the box body.

[0029] The main core 42 is provided with a second protrusion 47, a first protrusion 43 and a secondary hole protrusion 44 from front to back; the first protrusion 43 is used to form the first main hole on the box body, the second protrusion 47 is used to form the second main hole on the box body, and the secondary hole protrusion 44 is used to form the secondary hole on the box body.

[0030] In this mold, the box body of the cable box is formed by mating the box body cavity plate 2 and the box body core plate 4 in the box body mold; and the box body core plate 4 is provided with a main core 42 and a lead hole core 3. On the main core 42, a first protrusion 43 is located at the center of the main core 42, and a second protrusion 47 is provided close to the lead hole core 3 to form a first main hole, a second main hole, a secondary hole and a lead hole on the box body, thereby forming an improved box body structure, which is conducive to the efficient production of the improved HZ5-24 cable box.

[0031] In the improved HZ5-24 cable box, the first main hole is used to insert the main control cable (X1) from the signal tower or the previous electric switch machine, the second main hole is used to insert the branch cables (X2-X5) from the signal tower or the previous electric switch machine, the auxiliary hole is used to lead out the auxiliary cable, which is used to electrically connect to the next electric switch machine, and the lead wire hole is used to lead out the connecting cable, which is used to electrically connect to the electric switch machine near the cable box. That is, by setting the first main hole, the second main hole, and the auxiliary hole in the cable box, three independent holes can be set up to meet the requirement of simultaneously inserting three cables for long-distance three-phase AC turnout control, as well as the requirement that the indication circuit must be laid out separately with two cables. This allows the main control cable (X1) and the branch cables (X2-X5) to be arranged separately and independently, eliminating the influence of distributed capacitance between cable cores. This eliminates the safety hazard of the turnout indication relay not reliably dropping when the main control cable (X1) breaks, greatly improving the safety of the cable box.

[0032] In this embodiment, four positioning grooves 21 are provided around the box cavity plate 2; four positioning protrusions 41 are provided around the box core plate 4. When the box cavity plate 2 and the box core plate 4 are aligned, the positioning protrusions 41 are inserted into the positioning grooves 21 to achieve precise positioning of the box cavity plate 2 and the box core plate 4.

[0033] In this embodiment, at least one of the box cavity plate 2 and the box core plate 4 is provided with a glue injection hole. A glue injection machine is connected to the glue injection hole for injecting glue into the mold to form the box. In other embodiments, the box cavity plate 2 and the box core plate 4 may not be provided with any glue injection holes. In this case, the molding material can be placed between the box cavity plate 2 and the box core plate 4, and the box is formed directly by pressing the mold through the box cavity plate 2 and the box core plate 4. The specific molding process of the box is not specifically limited here.

[0034] The main core 42 is provided with multiple terminal slots, which are evenly arranged around the first protrusion 43.

[0035] In this embodiment, the terminal slot is used to form a fixing seat in the box body. The fixing seat is used to fix the double-row column magnetic terminals. Setting multiple terminal slots can realize the fixing of multiple double-row column magnetic terminals around the first main hole of the box body.

[0036] The double-row column-type magnetic terminal includes a row of inner chord terminals and a row of outer chord terminals. The row of outer chord terminals is located around the row of inner chord terminals, and adjacent inner and outer chord terminals are electrically connected to each other radially. In the improved HZ5-24 cable box, the double-row column-type magnetic terminal is used. The core wires of the main control cable and branch cables are connected to the inner chord magnetic terminals, while the core wires of the auxiliary cable and connecting cable are connected to the outer chord magnetic terminals. This allows the cable entering the cable box from upstream to the cable box and the cable leading downstream from the cable box to be connected to different magnetic terminals. During construction operations such as checking and confirming the cable core wires and the external lines of the electric switch machine, troubleshooting the turnout control and indication circuits, and tidying up the wiring inside the cable box, only the core wires on the inner or outer chord terminals need to be processed separately. This greatly reduces the probability of wiring errors, giving the cable box better wiring error prevention capabilities and improving the efficiency of its construction operations.

[0037] In this embodiment, four terminal slots are provided, and the four terminal slots are evenly arranged around the first protrusion 43.

[0038] In this embodiment, accessory grooves are also provided on both sides of the secondary hole protrusion 44. The accessory grooves are used to form fixing seats for other accessories in the box and to fix other accessories in the cable box.

[0039] Two embedded parts 46 are provided in each terminal slot. One embedded part 46 is used to form a fixing position for a double row of column magnetic terminals.

[0040] In this embodiment, two embedded parts 46 are provided in each terminal slot, thereby forming two fixed positions on each fixed seat, and the two ends of the double-row column magnetic terminal are respectively fixed on the fixed positions of two adjacent fixed seats.

[0041] The embedded part 46 includes a cylindrical section and a threaded section. A blind hole is provided at the position of the embedded part 46 in the terminal seat groove, and the cylindrical section of the embedded part 46 is movably assembled in the blind hole.

[0042] In this embodiment, the blind hole in the terminal slot is a cylindrical hole. After the cylindrical section of the embedded part 46 is inserted into the blind hole, the embedded part 46 is not completely fixed in the blind hole, but can be guided to move along the blind hole. At this time, the threaded section of the embedded part 46 extends out of the blind hole. When the material is injected into the box mold to form the box, the threaded section of the embedded part 46 is embedded in the box. After the box is taken out of the mold, the embedded part 46 can be removed from the box by rotating the embedded part 46 in the opposite direction, thereby forming a threaded hole on the box. This threaded hole is the fixing position of the double-row column magnetic terminal.

[0043] In this embodiment, a pre-embedded part 46 is also provided in the accessory slot, and a pre-embedded part 46 is also provided on the periphery of the main core 42 on the core plate 4 of the box body. The pre-embedded parts 46 are used to form threaded holes at the corresponding positions of the box body to facilitate the assembly and application of the box body.

[0044] The main core 42 and the two fixing plate cores 45 are all fixed to the core plate 4 of the box body by vertical pins, and the main core 42 and the lead hole core 3 are fixedly connected by horizontal pins.

[0045] In this embodiment, the upper surface of the box core plate 4 is provided with pin holes, and the lower surface of the main core 42 and the lower surface of the fixing plate core 45 are also provided with pin holes. One end of the pin is inserted into the pin hole on the box core plate 4, and the other end is inserted into the pin hole of the main core 42 or the fixing plate core 45, so as to fix the main core 42 and the fixing plate core 45 on the box core plate 4.

[0046] In this embodiment, the cross-sections of the cable box body and the box cover are both elliptical; the cross-section of the main core 42 is also elliptical. The fixing plate core 45 and the main core 42 are manufactured separately, which makes it easier to process and manufacture the main core 42.

[0047] Since the lead hole on the box body is not in the same plane as the first main hole, second main hole, and auxiliary hole on the main core 42, an independent lead hole core 3 is provided. The lead hole core 3 is fixed to the front side of the main core 42 by a horizontal pin, wherein the axis of the horizontal pin is perpendicular to the axis of the vertical pin. Pin holes are provided on one side of the lead hole core 3 and one side of the main core 42, and the pins are inserted into these pin holes to fix the lead hole core 3 and the main core 42 to each other. When demolding after the box body is formed, first separate the box body cavity plate 2 from the box body core plate 4, then remove the lead hole core 3 from the main core 42, and finally push the box body out of the main core 42.

[0048] The core plate 4 of the box body is provided with a guide groove. The extension direction of the guide groove is parallel to the axis of the transverse pin. The lead wire core 3 is guided and assembled in the guide groove.

[0049] In this embodiment, the lead hole core 3 moves along the guide groove. When the lead hole core 3 approaches the main core 42, the lead hole core 3 and the main core 42 are connected by a transverse pin. That is, the lead hole core 3 and the main core 42 are fixedly connected by a transverse pin. At the same time, the core plate 4 of the box body limits the lead hole core 3 by the guide groove, which together ensures the accurate positioning of the lead hole core 3 and the main core 42.

[0050] The box mold also includes a top plate 1, a bottom plate 7, and support blocks 5; the box cavity plate 2 is fixed on the top plate 1; two support blocks 5 are fixed on the bottom plate 7, and the box core plate 4 is fixed on the two support blocks 5.

[0051] In this embodiment, the box cavity plate 2 is installed on the top plate 1, and the box core plate 4 is installed on the bottom plate 7. The opening and closing movements of the box cavity plate 2 and the box core plate 4 can be realized by driving the top plate 1 and the bottom plate 7 to move relative to each other.

[0052] The box mold also includes a push plate 6 and an ejector rod 9. The push plate 6 is located between two support blocks 5. Multiple ejector rods 9 are provided on the push plate 6. The ejector rods 9 pass through the box core plate 4, the main core 42, and the fixing plate core 45.

[0053] In this embodiment, the push plate 6 is located within the space enclosed by the two support blocks 5, the bottom plate 7 and the core plate 4 of the box body. Multiple push rods 9 are provided, and the multiple push rods 9 are evenly distributed on the core plate 4 of the box body. Since the movement direction of the push rod 9 interferes with the installation direction of the lead hole core 3, the push rod 9 is not provided only within the range of the lead hole core 3.

[0054] A clearance hole is provided on the base plate 7. After the box body is formed, the box body cavity plate 2 and the box body core plate 4 move away from each other to open the mold. Then the lead wire hole core 3 is removed from the main core 42. At this time, the push mechanism passes through the clearance hole on the base plate 7 to push the push plate 6 to move. The push plate 6 drives the ejector rod 9 to move to push the formed box body out of the box body core plate 4.

[0055] At least one guide post 8 is provided between the base plate 7 and the core plate 4 of the box body. The push plate 6 is provided with a guide hole. The guide post 8 passes through the guide hole on the push plate 6 so that the push plate 6 moves along the guide post 8. A reset spring (not shown in the figure) is sleeved around the guide post 8. The reset spring is located between the core plate 4 of the box body and the push plate 6.

[0056] In this embodiment, two guide posts 8 are provided between the base plate 7 and the core plate 4 of the box body, and two guide holes are provided on the push plate 6. The two guide posts 8 pass through the two guide holes on the push plate 6 respectively, so that the push plate 6 moves along the two guide posts 8 at the same time, ensuring the stability of the movement of the push plate 6.

[0057] After the box body is removed from the core plate 4, the push mechanism is withdrawn. At this time, under the elastic force of the return spring, the push plate 6 is reset, and the push rod 9 retracts into the core plate 4.

[0058] Box lid mold includes: The lid cavity plate 200 has a lid cavity groove in the center to form the shape of the lid; the lid cavity plate 200 has multiple positioning grooves 21 around its perimeter.

[0059] The lid core plate 400 has a lid inner core at its center to form the inner cavity of the lid; the lid core plate 400 has multiple positioning protrusions 41 around its perimeter, which are used to be inserted into the positioning grooves 21.

[0060] In this embodiment, a mold for forming the cover of a cable box is formed by mating the cover cavity plate 200 and the cover core plate 400. In the cover forming mold, only the forming structure of the cover cavity plate 200 and the cover core plate 400 are different, while the rest of the structure is the same.

[0061] Specifically, the lid forming mold also includes a top plate 1, a bottom plate 7, support blocks 5, a push plate 6, and ejector rods 9; the lid cavity plate 200 is fixed on the top plate 1; two support blocks 5 are fixed on the bottom plate 7, and the lid core plate 400 is fixed on the two support blocks 5; the push plate 6 is located between the two support blocks 5, and multiple ejector rods 9 are provided on the push plate 6, the ejector rods 9 penetrating the lid core plate 400 and the lid inner core; at least one guide post 8 is provided between the bottom plate 7 and the lid core plate 400, and the push plate 6 is provided with a guide hole, the guide post 8 penetrating the guide hole on the push plate 6 to guide the push plate 6 to move along the guide post 8; a return spring is sleeved around the guide post 8, and the return spring is located between the lid core plate 400 and the push plate 6.
