Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to a mold for processing arc-blocking plates. Background Technology

[0002] An arc-extinguishing chamber is a device surrounding the contacts of a switch, used to limit the spatial position of the electric arc and accelerate its extinction. It is a small chamber that can introduce the electric arc and assist in its extinguishing. The arc-extinguishing plate is an important component of the arc-extinguishing chamber. In the existing technology, the arc-extinguishing plate is carried out by the gate during injection molding without the need for ejector pins to eject it from the mold. However, after demolding, a cutting action is still required to separate each arc-extinguishing plate from the material rod, which is labor-intensive, increases labor costs, and has low processing efficiency. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a mold for processing arc-blocking plates that enables fully automated production, saves labor costs, and improves production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mold for processing arc-blocking plates, comprising a moving mold assembly and a stationary mold assembly. The mold assembly and stationary mold assembly have several cavities for forming the arc-blocking plates at their joint. The mold also includes a glue injection channel with several glue injection channels inclined along the direction of the moving mold assembly. Each glue injection channel is connected to a corresponding cavity. A glue outlet is provided at the other end of each glue injection channel facing away from the glue injection channel. The inner diameter of the glue injection channel gradually decreases in size along the direction of the glue outlet, forming a cone shape. The glue outlet connects to the inner wall of the cavity and is located near the bottom center. A pusher assembly is provided on the other side of the moving mold assembly facing away from the stationary mold assembly for ejecting the formed arc-blocking plate from the cavity after mold opening.

[0005] By adopting the above technical solution, during the processing of the arc-blocking plate, the moving mold assembly and the stationary mold assembly are joined together. The injection material first enters the injection channel, and then enters the corresponding cavity through the injection channel and the dispensing port, where it is cooled and formed into an arc-blocking plate. After the arc-blocking plate is formed, the moving mold assembly and the stationary mold assembly move away from each other. Under the action of the pusher assembly, the arc-blocking plate is pushed out of the cavity, realizing fully automatic production. The inner diameter of the injection channel gradually decreases to a tapered shape along the direction of the dispensing port, and the setting of injecting the injection material into the cavity through the dispensing port can reduce the contact area between the finished arc-blocking plate and the dispensing port, eliminating glue dots on the appearance of the finished arc-blocking plate. At the same time, it can promote the automatic separation of the product from the dispensing port during demolding, eliminating the need for manual cutting operations, saving labor costs, and improving production efficiency. The inclined setting of the injection channel along the direction of the moving mold assembly and the setting of the dispensing port connecting to the inner side wall of the cavity and close to the bottom center make the cavity filling more stable and the injection faster and more uniform during injection, further improving the quality of the finished arc-blocking plate.

[0006] The present invention further comprises: the glue injection channel includes a main channel and multiple branch channels, each branch channel being evenly distributed on the left and right sides of the main channel with the main channel as the center, and each branch channel having a branch channel coaxially connected at its upper and lower ends, and the glue inlet channel being symmetrically connected on the left and right sides of each branch channel.

[0007] By adopting the above technical solution, the arrangement is reasonable and the glue injection is more uniform. The preferred glue injection method is a one-out-sixteen-in injection method. Sixteen cavities are set at the mold closing point of the moving mold assembly and the stationary mold assembly, which can form sixteen finished arc-blocking plates in one go. At the same time, four branch channels are distributed on the main channel, which are connected to the corresponding branch channels and glue injection channels respectively. One branch channel connects two vertically symmetrical branch channels, and one branch channel connects two horizontally symmetrical glue injection channels, making the glue injection faster and more uniform, and further improving the processing efficiency of the arc-blocking plates.

[0008] The present invention further comprises: the ejector assembly including a support base, an ejector plate and several ejector rods; the support base is disposed on the other side of the moving mold assembly away from the stationary mold assembly; the support base has a cavity; the ejector plate is slidably disposed in the cavity; the ejector rods are disposed on the ejector plate and are linked to the ejector plate; each ejector rod is evenly distributed at the bottom of each cavity and is connected to the cavity; the ejector plate drives the ejector rods to slide within the cavity.

[0009] By adopting the above technical solution, when the mold is opened, the moving mold assembly moves and separates from the stationary mold assembly. When the moving mold assembly moves to the demolding position, the external driving component causes the push plate to move along the direction of the stationary mold assembly. The ejector rod is linked with the push plate. When the push plate moves, the ejector rod is placed into the cavity along with the movement of the push plate, and pushes out the arc-blocking plate that has been injected into the cavity, thus completing the demolding of the arc-blocking plate. The structure is simple and the operation is convenient.

[0010] The present invention further comprises: a guide assembly is provided at each of the four corners of the push plate; the guide assembly includes a guide rod and a spring; the moving mold assembly is provided with a through channel for the guide rod to slide at the corresponding position of the guide rod; one end of the guide rod is connected to the push plate and the other end is placed in the through channel; the spring is sleeved on the outer periphery of the guide rod; one end of the spring abuts against the push plate and the other end abuts against the moving mold assembly.

[0011] By adopting the above technical solution, the guide component plays a role in moving and guiding. During demolding, the ejector pin is driven by the push plate to move towards the stationary mold assembly, causing it to push the arc-blocking plate in the cavity and detach it from the cavity. While the ejector pin moves, the guide post slides along the through-channel position with the push plate, further improving the stability of the ejector pin movement. The spring is sleeved on the outer periphery of the guide post, which not only stabilizes the structure but also plays a resetting role. When the arc-blocking plate is demolded, the spring causes the push plate to reset, resulting in a reasonable structure.

[0012] The present invention further includes the following: the moving mold assembly has an installation groove on the side facing the push plate, the installation groove is coaxially arranged with the through channel and adapted to the outer diameter of the spring, and the end of the spring facing away from the push plate abuts against the installation groove.

[0013] By adopting the above technical solution, the installation groove provides space for spring compression, further limiting the spring's position and preventing it from shifting during extension and retraction, thus ensuring the spring's usability.

[0014] The present invention further provides that the top and bottom walls of the cavity are both textured surfaces.

[0015] By adopting the above technical solutions, the appearance of the arc-blocking plate product is more aesthetically pleasing. Compared with the smooth surface, it is less prone to scratches, reducing the defect rate. The textured surface of the top and bottom walls is preferably an etched textured surface in the static mold direction and a pulsed textured surface in the moving mold direction. This simplifies processing, facilitates demolding, improves processing efficiency, and further enhances the aesthetics of the appearance. Attached Figure Description

Detailed Implementation

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0023] See appendix Figure 1-5 This utility model discloses a mold for processing arc-blocking plates, including a moving mold assembly 1 and a stationary mold assembly 2. The mold part where the moving mold assembly 1 and the stationary mold assembly 2 are joined is provided with a plurality of cavities 3 for forming arc-blocking plates. It also includes a glue injection channel 4 for injection. The glue injection channel 4 is provided with a plurality of glue injection channels 5 that are inclined along the direction of the moving mold assembly 1. Each glue injection channel 5 is respectively connected to each cavity 3. The other end of the glue injection channel 5 facing away from the glue injection channel 4 is provided with a glue outlet 6. The inner diameter of the glue injection channel 5 gradually decreases and becomes conical along the direction of the glue outlet 6. The glue outlet 6 is connected to the inner wall of the cavity 3 and is close to the bottom center. The other side of the moving mold assembly 1 facing away from the stationary mold assembly 2 is provided with a pusher assembly 7 for ejecting the formed arc-blocking plate out of the cavity 3 after the mold is opened. During the processing of the arc-blocking plate, the moving mold assembly 1 and the stationary mold assembly 2 are closed. The injection material first enters the injection channel 4, and then enters the corresponding cavity 3 through the injection channel 5 and the dispensing port 6, where it cools and solidifies into an arc-blocking plate. After the arc-blocking plate is formed, the moving mold assembly 1 and the stationary mold assembly 2 move away from each other. Under the action of the ejector assembly 7, the arc-blocking plate is pushed out of the cavity 3, realizing fully automated production. The inner diameter of the injection channel 5 gradually decreases to a tapered shape along the direction of the dispensing port 6, and the setting of injecting the injection material into the cavity 3 through the dispensing port 6 reduces the contact area between the finished arc-blocking plate and the dispensing port 6, eliminating glue marks on the appearance of the finished arc-blocking plate. At the same time, it facilitates automatic separation of the product from the dispensing port 6 during demolding, eliminating the need for manual cutting operations and saving labor costs. To improve production efficiency, the glue inlet channel 5 is inclined along the direction of the moving mold assembly 1 and the glue outlet 6 is connected to the inner wall of the cavity 3 and located near the bottom center. This makes the filling of the cavity 3 more stable and the glue inlet faster and more uniform when it is filled, thereby further improving the finished quality of the arc-blocking plate.

[0024] This embodiment further includes the following configuration: the injection channel 4 comprises a main channel 401 and multiple branch channels 402. Each branch channel 402 is evenly distributed on the left and right sides of the main channel 401 with the main channel 401 as the center. The upper and lower ends of each branch channel 402 are coaxially connected to a branch channel 8. The injection channel 5 is symmetrically connected on the left and right sides of each branch channel 8. The arrangement is reasonable, and the injection is more uniform. Preferably, it is a one-outlet-sixteen-inlet injection method. The mold closing point of the moving mold assembly 1 and the stationary mold assembly 2 is provided with sixteen cavities 3, which can form sixteen arc-blocking plate finished products in one step. At the same time, four branch channels 402 are distributed on the main channel 401, which are respectively connected to the corresponding branch channels 8 and injection channels 5. One branch channel 402 is connected to two vertically symmetrical branch channels 8, and one branch channel 8 is connected to two horizontally symmetrical injection channels 5. The injection is faster and more uniform, further improving the processing efficiency of the arc-blocking plate. The number of branch channels 402 can be increased or decreased according to the size of the mold.

[0025] This embodiment further includes the following configuration: the pusher assembly 7 includes a support base 701, a push plate 702, and several push rods 703. The support base 701 is located on the other side of the moving mold assembly 1 facing away from the stationary mold assembly 2. A cavity 9 is provided inside the support base 701. The push plate 702 is slidably fitted inside the cavity 9. The push rods 703 are mounted on the push plate 702 and are linked with the push plate 702. Each push rod 703 is evenly distributed at the bottom of each cavity 3 and is connected to the cavity 3. The push plate 702 drives the push rods 703 to slide within the cavity 3. When the mold is opened, the moving mold assembly 1 moves and separates from the stationary mold assembly 2. When the moving mold assembly 1 moves to the demolding position, the external driving component causes the push plate 702 to move along the direction of the stationary mold assembly 2. The ejector rod 703 is linked with the push plate 702. When the push plate 702 moves, the ejector rod 703 is placed into the cavity 3 along with the movement of the push plate 702, and pushes out the arc partition plate that has been injected into the cavity 3, thus completing the demolding of the arc partition plate. The structure is simple and the operation is convenient.

[0026] This embodiment further includes the following configuration: guide components 10 are respectively provided at the four corners of the push plate 702. Each guide component 10 includes a guide rod 1001 and a spring 1002. The moving mold component 1 is provided with a through channel 11 for the guide rod 1001 to slide at the corresponding position. One end of the guide rod 1001 is connected to the push plate 702, and the other end is placed in the through channel 11. The spring 1002 is sleeved on the outer periphery of the guide rod 1001. One end of the spring 1002 abuts against the push plate 702, and the other end abuts against the moving mold component 1. The guide component 10 serves as a moving guide. During demolding, the ejector pin 703 is driven by the push plate 702 to move towards the stationary mold component 2, causing it to push the arc-blocking plate inside the cavity 3, causing it to detach from the cavity 3. While the ejector pin 703 moves, the guide post slides along the through channel 11 driven by the push plate 702, further improving the stability of the ejector pin 703's movement. The spring 1002 is sleeved on the outer periphery of the guide post, providing structural stability and a reset function. When the arc-blocking plate is demolded, the spring 1002 causes the push plate 702 to reset, resulting in a reasonable structure.

[0027] This embodiment further includes the following configuration: The moving mold assembly 1 has a mounting groove 12 on the side facing the push plate 702. The mounting groove 12 is coaxially aligned with the through channel 11 and is adapted to the outer diameter of the spring 1002. The end of the spring 1002 facing away from the push plate 702 abuts against the mounting groove 12. The mounting groove 12 provides space for the spring 1002 to compress, further limiting its movement and preventing displacement, thus ensuring its usability.

[0028] This embodiment further specifies that the top and bottom walls of the cavity 3 are both textured surfaces. This makes the appearance of the arc-blocking plate product more aesthetically pleasing, less prone to scratches compared to a smooth surface, and reduces the defect rate. Preferably, the textured surfaces of the top and bottom walls are corrosion-textured in the stationary mold direction and pulse-textured in the moving mold direction, simplifying processing, facilitating demolding, improving processing efficiency, and further enhancing the aesthetic appearance.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
