Description

Technical Field

[0001] This utility model relates to the field of insulating shaft / rod manufacturing technology, specifically to a multi-cavity insulating shaft / rod mold. Background Technology

[0002] Insulating shafts / rods play a crucial role in insulation and transmission in switchgear. Due to their unique structure and large quantity usage, single-cavity molds currently face several shortcomings in producing these components: Firstly, production efficiency is low. A single mold contains only one gate, producing only one product at a time, resulting in a large workload for pouring and demolding. Secondly, consistent process control for shafts / rods is difficult; single-cavity molds are more susceptible to fluctuations in process parameters such as temperature, affecting product stability. Finally, single-cavity molds have low overall efficiency, low capacity per unit volume, require significant space, cannot be integrated with demolding machines for mechanized operations, and repeated mold opening and closing accelerates wear, leading to high long-term maintenance costs. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a multi-cavity mold for insulating shafts and rods, used for the multi-cavity production of insulating shafts / rods. It can be used with a demolding machine to achieve mechanized assembly and disassembly operations, reducing manual labor, greatly improving production efficiency, and lowering maintenance costs.

[0004] This utility model is achieved through the following technical solution: a multi-cavity insulating shaft mold, comprising a left module, a center module, and a right module arranged in sequence, wherein the left module, center module, and right module are detachably fixedly connected, and several mold cavity groups are provided between the left module and the center module, and between the right module and the center module. Each mold cavity group includes a pouring channel and multiple mold cavities. The tail of the pouring channel has multiple branch channels, each branch channel connecting to a mold cavity. The mold cavity includes a fixed half-mold cavity opened on the side wall of the center module, and a movable half-mold cavity opened on the inner side wall of the left module or the right module. Insert positioning blocks are installed at both ends inside the mold cavity.

[0005] This solution uses left and right modules that interface with the central module to create multiple mold cavity groups, increasing mold production capacity. Each mold cavity group contains multiple mold cavities, achieving multi-cavity molds and further increasing production output. Operators can mold multiple products in a single setup, reducing manual labor, significantly improving production efficiency, and lowering maintenance costs.

[0006] As an optimization, each mold cavity group includes two mold cavities arranged horizontally, with the casting channel located between the two mold cavities. This optimized solution improves uniformity by placing the casting channel between the two mold cavities, allowing the casting liquid to flow evenly into the mold cavities on both sides.

[0007] As an optimization, two mold cavity groups are provided between the left module and the center module, and between the right module and the center module, with the two mold cavity groups arranged horizontally. This optimization further improves the production efficiency of the mold.

[0008] As an optimization, handles are installed on the outer walls of both the left and right modules. This optimization allows for convenient adjustment of the mold position and facilitates the movement of the left and right modules.

[0009] As an optimization, several gating boxes are installed on the outer walls of both the left and right modules. The number of gating boxes is the same as the number of mold cavity groups, and the positions of the gating boxes correspond to the gating channels of the mold cavity groups. The gating boxes are opened on the side facing the left or right module, and water injection holes are provided on the gating boxes. This optimization scheme injects room temperature water into the gating boxes, keeping the temperature near the gating channels relatively low, thereby delaying the curing of epoxy resin near the gating gate and facilitating shrinkage compensation in other areas.

[0010] As an optimization, grooves are formed on the outer walls of the left and right modules opposite to the inner cavity of the gating box. This optimization reduces the distance between the inner cavity of the gating box and the pouring channel by forming grooves, and increases the volume of the gating box, further improving the delay effect.

[0011] As an optimization, the center module has pry openings on the edges of its two side walls facing the left and right modules. In this optimized design, when disassembling the left and right modules from the center module, the pry openings are used to separate the left and right modules, improving disassembly efficiency and convenience.

[0012] As an optimization, positioning pins are installed on the two side walls of the central module facing the left and right modules, and positioning holes that mate with the positioning pins are provided on the inner side walls of the left and right modules. In this optimized solution, when the left and right modules are molded with the central module, the positioning pins and positioning holes work together to accurately position the modules, ensuring the accuracy of mold closing and improving mold closing efficiency.

[0013] The beneficial effects of this invention are as follows: By connecting and cooperating the left and right modules with the central module, the mold forms multiple mold cavity groups, increasing the mold's production capacity. Each mold cavity group contains multiple mold cavities, achieving a multi-cavity mold and further increasing production capacity. Operators can mold multiple products in a single mold setup, reducing manpower workload, greatly improving production efficiency, reducing space occupation, and lowering maintenance costs.

[0015] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0016] like Figures 1-6 As shown, a multi-cavity insulating shaft mold includes a left module 1, a center module 2, and a right module 3 arranged in sequence, wherein the left module 1, the center module 2, and the right module 3 are detachably fixed together.

[0017] Specifically, the left module 1, the center module 2, and the right module 3 are connected by mold-closing fixing bolts 9. Each of the left module 1, center module 2, and right module 3 has bolt holes 91 for the mold-closing fixing bolts 9 to pass through. In this embodiment, the left module 1, center module 2, and right module 3 are detachably fixed together by six evenly distributed mold-closing fixing bolts 9 to ensure a secure connection.

[0018] Several mold cavity groups 4 are provided between the left module 1 and the center module 2, and between the right module 3 and the center module 2. Each mold cavity group 4 includes a pouring channel 42 and multiple mold cavities 41. The tail of the pouring channel 42 has multiple branch channels 43. The number of branch channels 43 is the same as the number of mold cavities. Each branch channel 43 is connected to a mold cavity 41.

[0019] By connecting and cooperating with the left module 1 and right module 3 respectively with the central module 2, mold cavity groups 4 are formed on both sides of the central module 2, thereby increasing the mold's production capacity. Each mold cavity group 4 contains multiple mold cavities 41, realizing a single mold with multiple cavities, thus further increasing mold production capacity. Operators can mold multiple products in one mold setup, reducing manpower workload, greatly improving production efficiency, and reducing maintenance costs.

[0020] In this embodiment, two mold cavity groups 4 are provided between the left module 1 and the central module 2, and between the right module 3 and the central module 2, respectively. The two mold cavity groups 4 are arranged horizontally. Each mold cavity group 4 includes two mold cavities 41, which are arranged horizontally, and the pouring channel is located between the two mold cavities 41. By placing the pouring channel 42 between the two mold cavities 41, the pouring liquid flows evenly into the mold cavities 41 on both sides, improving uniformity.

[0021] Specifically, the mold cavity 41 includes a fixed half-mold cavity 411 opened on the side wall of the central module 2, and a movable half-mold cavity 412 opened on the inner side wall of the left module 1 or the right module 3. Insert positioning blocks 5 are installed at both ends inside the mold cavity 41.

[0022] In this embodiment, fixed half-mold cavities 411 are formed on the left and right side walls of the central module 2, and movable half-mold cavities 412 are formed on the right side wall of the left module 1 and the left side wall of the right module 3. When the left module 1 and the right module 3 are connected to the central module 2, the movable half-mold cavity 412 and the fixed half-mold cavity 411 are connected to form a mold cavity 41. The upper and lower ends of the mold cavity 41 are externally connected. The upper and lower ends of the mold cavity 41 are respectively sealed by two insert positioning blocks 5, so that the inner cavity of the mold cavity 41 forms a casting cavity that matches the shape of the insulating shaft. Epoxy resin is injected into the casting cavity through the casting channel 42.

[0023] To improve the sealing performance of the insert positioning block 5, a sealing ring is fixed to the outer wall of the insert positioning block 5 to prevent epoxy resin leakage.

[0024] Specifically, the gating channel 42 is located at the top of the mold and extends downwards. Two branch channels 43 branch off at the bottom of the gating channel 42, each communicating with one of the two gating cavities. The gating channel 42 includes a fixed half-channel 421 and a movable half-channel 422. The fixed half-channel 421 is located on the side wall of the central module 2 and communicates with the fixed half-mold cavity 411. The movable half-channel 422 is located on the inner side wall of the left module 1 or the right module 3 and communicates with the movable half-mold cavity 412.

[0025] Handles 8 are installed on the outer walls of both the left module 1 and the right module 3. The handles 8 facilitate the adjustment of the mold position and the movement of the left module 1 and the right module 3.

[0026] In this embodiment, three handles 8 are installed on the outer walls of both the left module 1 and the right module 3, and the three handles 8 are evenly distributed.

[0027] Both the left module 1 and the right module 3 have several gating boxes 7 installed on their outer side walls. The number of gating boxes 7 is the same as that of the mold cavity group 4, and the positions of the gating boxes 7 correspond to the gating channels 42 of the mold cavity group 4. The gating boxes 7 are opened on the side facing the left module 1 or the right module 3, and each gating box 7 has a water injection hole 71. By injecting room temperature water into the gating boxes 7, the temperature near the gating channels 42 is kept relatively low, thereby delaying the curing of the epoxy resin near the gating channels and facilitating shrinkage compensation in other areas.

[0028] The left module 1 and right module 3 have recessed grooves 12 on their outer side walls opposite to the inner cavity of the pouring water box 7. By creating the recessed grooves 12, the distance from the inner cavity of the pouring water box 7 to the pouring channel 42 is reduced, thereby increasing the volume of the pouring water box and further improving the delay effect.

[0029] In this embodiment, there are two mold cavity groups 4 between the left module 1 and the central module 2, so two gating boxes 7 are installed on the outer wall of the left module 1. There are also two mold cavity groups 4 between the right module 3 and the central module 2, so two gating boxes 7 are installed on the outer wall of the right module 3.

[0030] Preferably, the pouring water box 7 is detachably fixed to the left module 1 or the right module 3 by bolts.

[0031] The central module 2 has pry holes 6 on the edges of its two side walls facing the left module 1 and the right module 3. In this optimized solution, when the left module 1 and the right module 3 are demolded from the central module 2, the pry holes 6 are used to pry the left module 1 and the right module 3 apart from the central module 2, thereby improving demolding efficiency and convenience.

[0032] As an optimization, positioning pins 10 are installed on the two side walls of the central module 2 facing the left module 1 and the right module 3, and positioning holes 101 that cooperate with the positioning pins 10 are provided on the inner side walls of the left module 1 and the right module 3. In this optimized solution, when the left module 1 and the right module 3 are molded with the central module 2, the positioning pins 10 and the positioning holes 101 cooperate to accurately position them, ensuring the accuracy of mold closing and improving mold closing efficiency.

[0033] Positioning pins 10 are installed on the two side walls of the central module 2 facing the left module 1 and the right module 3. Positioning holes 101 that cooperate with the positioning pins 10 are provided on the inner side walls of the left module 1 and the right module 3. When the left module 1 and the right module 3 are molded with the central module 2, the positioning pins 10 and the positioning holes 101 cooperate to accurately position the mold, ensuring the accuracy of mold closing and improving the efficiency of mold closing.

[0034] The central module 2 has pry holes 6 on the edges of its two side walls facing the left module 1 and the right module 3. When the left module 1 and the right module 3 are molded from the central module 2, the pry holes 6 are used to pry the left module 1 and the right module 3 apart from the central module 2, improving the efficiency and convenience of mold disassembly.

[0035] In this embodiment, both the left module 1 and the right module 3 are threaded with set screws (not shown in the figure). The set screws pass through the left module 1 or the right module 3 and contact the side wall of the center module 2. When the left module 1, the right module 3 and the center module 2 are to be opened, the set screws are rotated to push the left module 1 or the right module 3 open, which is convenient and labor-saving.

[0036] In this embodiment, lifting rings 11 are fixed to the circumferential edges of the left module 1, the central module 2, and the right module 3 for hoisting the mold to the demolding machine for fixation, thereby achieving mechanized demolding. The installation of the demolding machine and the mold is existing technology and will not be described in detail here.

[0037] Working principle: During mold assembly, the mold is first fixed on the demolding machine. The left and right half molds are moved parallel to open the mold. After the inserts are installed, the mold is closed horizontally, and the mold closing fixing bolts 9 are tightened to fix the left module 1, center module 2, and right module 3 into a whole. Room temperature water is injected into the sprue water box 7 through the water injection hole 71 to keep the area near the gating channel 42 at a relatively low temperature. Epoxy resin is injected into the mold cavity 41 through the gating channel 42. During demolding, the mold is fixed on the demolding machine, and the left module 1, right module 3 and center module 2 are separated. After the product is removed, the mold is reassembled for the next round of production.

Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
